     ville@badger[~]|2> %store A\\
     ville@badger[~]|3> Exit

     ville@badger[~]|1> print A
     
     ['hello', 10, 'world']
     
     Usage:
     
     %store          - Show list of all variables and their current values\\
     %store <var>    - Store the *current* value of the variable to disk\\
     %store -d <var> - Remove the variable and its value from storage\\
     %store -z       - Remove all variables from storage\\
     %store -r       - Refresh all variables from store (delete current vals)\\
     %store foo >a.txt  - Store value of foo to new file a.txt\\
     %store foo >>a.txt - Append value of foo to file a.txt\\   
     
     It should be noted that if you change the value of a variable, you
     need to %store it again if you want to persist the new value.
     
     Note also that the variables will need to be pickleable; most basic
     python types can be safely %stored.
     
     Also aliases can be %store'd across sessions.

[phone]  Ville Vainio <[e-mail]>
+
+	* ipython.rst, ipython.1: remove -twisted from man page,
+	add -pydb to both man page and manual.
+
+	* pspersistence.py: report UsageError on %store -w w/o arg,
+	and other usage pattern errors. Bug report by Johann Cohen-Tanugi.
+
 2008-06-02  Fernando Perez  <[e-mail]>
 
 	* IPython/Shell.py (MatplotlibShellBase._matplotlib_config): add
 	numpy/np/pyplot/plt imports according to new conventions we're
 	trying to standardize on.  This only affects the -pylab mode.
 
[phone]  Fernando Perez  <[e-mail]>
+
+	* IPython/ipmaker.py (make_IPython): The -twisted option is fully
+	disabled.
+
 2008-05-31  *** Released version 0.8.4
 
 2008-05-31  Fernando Perez  <[e-mail]>
 
 	* IPython/ipmaker.py (make_IPython): The -twisted option is fully
 	disabled.
 
 	* IPython/Shell.py (_select_shell): completely disable -twisted.
 	This code is of dubious quality and  normal users should not
 	encounter it until we can clarify things further, even under
 	win32.  Since we need a quick emergency 0.8.4 release, it is now
 	disabled completely.  Users who want to run it can use the
 	following command (it's easy to put it in an alias or script):
 	
 	python -c"from IPython import twshell;twshell.IPShellTwisted().mainloop()"
 
 2008-05-30  Ville Vainio <[e-mail]>
 
 	* shell.py: disable -twisted on non-win32 platforms.
 	import sets module on python 2.3.
 
 	* ipy_profile_sh.py: disable ipy_signals. Now, ipython
 	is verified to work with python 2.3
 	
 	* Release.py: update version to 0.8.4 for quick point fix
 
 2008-05-28  *** Released version 0.8.3
 
 2008-05-28  Fernando Perez  <[e-mail]>
 
 	* ../win32_manual_post_install.py (run): Fix the windows installer
 	so the links to the docs are correct.
 
 	* IPython/ultraTB.py: flush stderr after writing to it to fix
 	problems with exception traceback ordering in some platforms.
 	Thanks to a report/fix by Jie Tang <jietang86-AT-gmail.com>.
 
 	* IPython/Magic.py (magic_cpaste): add stripping of continuation
 	prompts, feature requested by Stefan vdW.
 
 	* ../setup.py: updates to build and release tools in preparation
 	for 0.8.3 release.
 
 2008-05-27  Ville Vainio <[e-mail]>
 
 	* iplib.py, ipmaker.py: survive lack of doctest and site._Helper
 	for minimal environments (e.g. Maemo sdk python)
 
 	* Magic.py: cpaste strips whitespace before >>> (allow pasting
 	doctests)
 
 	* ipy_completers.py: cd completer now does recursive path expand
 	(old behaviour is buggy on some readline versions)
 
 2008-05-14  Ville Vainio <[e-mail]>
 
 	* Extensions/ipy_greedycompleter.py: 
 	New extension that enables a bit more "relaxed" tab 
 	completer that evaluates code without safety checks
 	(i.e. there can be side effects like function calls)
 
 2008-04-20  Ville Vainio <[e-mail]>
 
 	* Extensions/ipy_lookfor.py: add %lookfor magic command
 	(search docstrings for words) by Pauli Virtanen. Close #245.
 
 	* Extension/ipy_jot.py: %jot and %read magics, analogous
 	to %store but you can specify some notes. Not read 
 	in automatically on startup, you need %read.
 	Contributed by Yichun Wei.
 
 2008-04-18  Fernando Perez  <[e-mail]>
 
 	* IPython/genutils.py (page): apply workaround to curses bug that
 	can leave terminal corrupted after a call to initscr().
 
 2008-04-15  Ville Vainio <[e-mail]>
 
 	* genutils.py: SList.grep supports 'field' argument
 
 	* ipy_completers.py: module completer looks inside
 	.egg zip files (patch by mc). Close #196.
 
 2008-04-09  Ville Vainio <[e-mail]>
 
 	* deep_reload.py: do not crash on from __future__ import 
 	absolute_import. Close #244.
 
 2008-04-02  Ville Vainio <[e-mail]>
 
 	* ipy_winpdb.py: New extension for winpdb integration.  %wdb
 	test.py is winpdb equivalent of %run -d test.py.  winpdb is a
 	crossplatform remote GUI debugger based on wxpython.
 
 2008-03-29  Ville Vainio <[e-mail]>
 
 	* ipython.rst, do_sphinx.py: New documentation base, based on
 	reStucturedText and Sphinx (html/pdf generation).  The old Lyx
 	based documentation will not be updated anymore.
 
 	* jobctrl.py: Use shell in Popen for 'start' command (in windows).
 
 2008-03-24  Ville Vainio <[e-mail]>
 
 	* ipython.rst, do_sphinx.py: New documentation base, based on
 	reStucturedText and Sphinx (html/pdf generation).  The old Lyx
 	based documentation will not be updated anymore.
 
 	ipython.rst has up to date documentation on matters that were not
 	documented at all, and it also removes various
 	misdocumented/deprecated features.
 	
 2008-03-22  Ville Vainio <[e-mail]>
 
 	* Shell.py: Merge mtexp branch:
 	https://code.launchpad.net/~ipython/ipython/mtexp
 
 	Privides simpler and more robust MTInteractiveShell that won't
 	deadlock, even when the worker thread (GUI) stops doing runcode()
 	regularly. r71.
 
 2008-03-20  Ville Vainio <[e-mail]>
 
 	* twshell.py: New shell that runs IPython code in Twisted reactor.
 	Launch by doing ipython -twisted. r67.
 
 2008-03-19  Ville Vainio <[e-mail]>
 
 	* Magic.py: %rehashx works correctly when shadowed system commands
 	have upper case characters (e.g. Print.exe). r64.
 
 	* ipy_bzr.py, ipy_app_completers.py: new bzr completer that also
 	knows options to commands, based on bzrtools. Uses bzrlib
 	directly. r66.
 
 2008-03-16  Ville Vainio <[e-mail]>
 
 	* make_tarball.py: Fixed for bzr.
 
 	* ipapi.py: Better _ip.runlines() script cleanup. r56,r79.
 
 	 * ipy_vimserver.py, ipy.vim: New extension for vim server mode,
 	 by Erich Heine.
 
 2008-03-12  Ville Vainio <[e-mail]>
 
 	* ipmaker.py: Force (reload?) import of ipy_user_conf and
 	ipy_profile_foo, so that embedded instances can be relaunched and
 	configuration is still done. r50
 
 	* ipapi.py, test_embed.py: Allow specifying shell class in
 	launch_new_instance & make_new instance. Use this in
 	test_embed.py. r51.
 
 	test_embed.py is also a good and simple demo of embedding IPython.
 	
 
 2008-03-10  Ville Vainio <[e-mail]>
 
 	* tool/update_revnum.py: Change to bzr revisioning scheme in 
 	revision numbers.
 
 	* Shell.py: Threading improvements:
 
 	In multithreaded shells, do not hang on macros and o.autoexec
 	commands (or anything executed with _ip.runlines()) anymore. Allow
 	recursive execution of IPython code in
 	MTInteractiveShell.runsource by checking if we are already in
 	worker thread, and execute code directly if we are. r48.
 
 	MTInteractiveShell.runsource: execute code directly if worker
 	thread is not running yet (this is the case in config files). r49.
 
 2008-03-09  Ville Vainio <[e-mail]>
 
 	* ipy_profile_sh.py: You can now use $LA or LA() to refer to last
 	argument of previous command in sh profile. Similar to bash '!$'.
 	LA(3) or $LA(3) stands for last argument of input history command 
 	3.
 
 	* Shell.py: -pylab names don't clutter %whos listing.
 
 2008-03-07  Ville Vainio <[e-mail]>
 
 	* ipy_autoreload.py: new extension (by Pauli Virtanen) for 
 	autoreloading modules; try %autoreload and %aimport. Close #154.
 	Uses the new pre_runcode_hook.
 
 2008-02-24  Ville Vainio <[e-mail]>
 
 	* platutils_posix.py: freeze_term_title works
 
 2008-02-21  Ville Vainio <[e-mail]>
 
 	* Magic.py: %quickref does not crash with empty docstring
 
 2008-02-20  Ville Vainio <[e-mail]>
 
 	* completer.py: do not treat [](){} as protectable chars anymore,
 	close #233.
 
 	* completer.py: do not treat [](){} as protectable chars anymore
 	
 	* magic.py, test_cpaste.py: Allow different prefix for pasting 
 	from email
 
 2008-02-17  Ville Vainio <[e-mail]>
 
 	* Switched over to Launchpad/bzr as primary VCS.
 
 2008-02-14  Ville Vainio <[e-mail]>
 
 	* ipapi.py: _ip.runlines() is now much more liberal about 
 	indentation - it cleans up the scripts it gets
 	
 2008-02-14  Ville Vainio <[e-mail]>
 
 	* Extensions/ipy_leo.py: created 'ILeo' IPython-Leo bridge.
 	Changes to it (later on) are too numerous to list in ChangeLog
 	until it stabilizes
 	
 2008-02-07  Darren Dale <[e-mail]>
 
 	* IPython/Shell.py: Call QtCore.pyqtRemoveInputHook() when creating
 	an IPShellQt4. PyQt4-4.2.1 and later uses PyOS_InputHook to improve 
 	interaction in the interpreter (like Tkinter does), but it seems to 
 	partially interfere with the IPython implementation and exec_()
 	still seems to block. So we disable the PyQt implementation and
 	stick with the IPython one for now.
 
 2008-02-02  Walter Doerwald  <[e-mail]>
 
 	* ipipe.py: A new ipipe table has been added: ialias produces all
 	entries from IPython's alias table.
 	
 2008-02-01  Fernando Perez  <[e-mail]>
 
 	* IPython/Shell.py (MTInteractiveShell.runcode): Improve handling
 	of KBINT in threaded shells.  After code provided by Marc in #212.
 
 2008-01-30  Fernando Perez  <[e-mail]>
 
 	* IPython/Shell.py (MTInteractiveShell.__init__): Fixed deadlock
 	that could occur due to a race condition in threaded shells.
 	Thanks to code provided by Marc, as #210.
 
 2008-01-29  Fernando Perez  <[e-mail]>
 
 	* IPython/Magic.py (magic_doctest_mode): respect the user's
 	settings for input separators rather than overriding them.  After
 	a report by Jeff Kowalczyk <jtk-AT-yahoo.com>
 
 	* IPython/history.py (magic_history): Add support for declaring an
 	output file directly from the history command.
 
 2008-01-21  Walter Doerwald  <[e-mail]>
 
 	* ipipe.py: Register ipipe's displayhooks via the generic function
 	generics.result_display() instead of using ipapi.set_hook().
 	
 2008-01-19  Walter Doerwald  <[e-mail]>
 
 	* ibrowse.py, igrid.py, ipipe.py:
 	The input object can now be passed to the constructor of the display classes.
 	This makes it possible to use them with objects that implement __or__.
 	Use this constructor in the displayhook instead of piping.
 
 	* ipipe.py: Importing astyle.py is done as late as possible to
 	avoid problems with circular imports.
 	
 2008-01-19 Ville Vainio  <[e-mail]>
 
 	* hooks.py, iplib.py: Added 'shell_hook' to customize how
 	IPython calls shell.
 
 	* hooks.py, iplib.py: Added 'show_in_pager' hook to specify
 	how IPython pages text (%page, %pycat, %pdoc etc.)
 
 	* Extensions/jobctrl.py: Use shell_hook. New magics: '%tasks'
 	and '%kill' to kill hanging processes that won't obey ctrl+C.
 
 2008-01-16 Ville Vainio  <[e-mail]>
 
 	* ipy_completers.py: pyw extension support for %run completer.
 
 2008-01-11 Ville Vainio  <[e-mail]>
 
 	* iplib.py, ipmaker.py: new rc option - autoexec. It's a list 
 	of ipython commands to be run when IPython has started up
 	(just before running the scripts and -c arg on command line).
 	
 	* ipy_user_conf.py: Added an example on how to change term 
 	colors in config file (through using autoexec).
 
 	* completer.py, test_completer.py: Ability to specify custom
 	get_endidx to replace readline.get_endidx. For emacs users.
 	
 2008-01-10 Ville Vainio  <[e-mail]>
 
 	* Prompts.py (set_p_str): do not crash on illegal prompt strings
 
 2008-01-08 Ville Vainio  <[e-mail]>
 
 	* '%macro -r' (raw mode) is now default in sh profile.
 
 2007-12-31  Ville Vainio  <[e-mail]>
 
 	* completer.py: custom completer matching is now case sensitive
 	(#207).
 	
 	* ultraTB.py, iplib.py: Add some KeyboardInterrupt catching in
 	an attempt to prevent occasional crashes.
 	
 	* CrashHandler.py: Crash log dump now asks user to press enter
 	before exiting.
 	
 	* Store _ip in user_ns instead of __builtin__, enabling safer
 	coexistence of multiple IPython instances in the same python
 	interpreter (#197).
 	
 	* Debugger.py, ipmaker.py: Need to add '-pydb' command line
 	switch to enable pydb in post-mortem debugging and %run -d.
 
 2007-12-28  Ville Vainio  <[e-mail]>
 
 	* ipy_server.py: TCP socket server for "remote control" of an IPython 
 	instance.
 	
 	* Debugger.py: Change to PSF license
 	
 	* simplegeneric.py: Add license & author notes.
 	
 	* ipy_fsops.py: Added PathObj and FileObj, an object-oriented way 
 	to navigate file system with a custom completer. Run 
 	ipy_fsops.test_pathobj() to play with it.
 
 2007-12-28  Fernando Perez  <[e-mail]>
 
 	* IPython/dtutils.py: Add utilities for interactively running
 	doctests.  Still needs work to more easily handle the namespace of
 	the package one may be working on, but the basics are in place.
 
 2007-12-27  Ville Vainio  <[e-mail]>
 
 	* ipy_completers.py: Applied arno's patch to get proper list of 
 	packages in import completer. Closes #196.

 	See generics.py / my_demo_complete_object
 
 2007-12-13  Fernando Perez  <[e-mail]>
 
 	* IPython/Prompts.py (BasePrompt.__nonzero__): add proper boolean
 	behavior to prompt objects, useful for display hooks to adjust
 	themselves depending on whether prompts will be there or not.
 
 2007-12-13  Ville Vainio  <[e-mail]>
 
 	* iplib.py(raw_input): unix readline does not allow unicode in
 	history, encode to normal string. After patch by Tiago.
 	Close #201
 
 2007-12-12  Ville Vainio  <[e-mail]>
 
 	* genutils.py (abbrev_cwd): Terminal title now shows 2 levels of 
 	current directory.
 	
 2007-12-12  Fernando Perez  <[e-mail]>
 
 	* IPython/Shell.py (_select_shell): add support for controlling
 	the pylab threading mode directly at the command line, without
 	having to modify MPL config files.  Added unit tests for this
 	feature, though manual/docs update is still pending, will do later.
 
 2007-12-11  Ville Vainio  <[e-mail]>
 
 	* ext_rescapture.py: var = !cmd is no longer verbose (to facilitate
 	use in scripts)
 
 2007-12-07  Ville Vainio  <[e-mail]>
 
 	* iplib.py, ipy_profile_sh.py: Do not escape # on command lines 
 	anymore (to \#) - even if it is a comment char that is implicitly 
 	escaped in some unix shells in interactive mode, it is ok to leave
 	it in IPython as such.
 
 
 2007-12-01  Robert Kern  <[e-mail]>
 
 	* IPython/ultraTB.py (findsource): Improve the monkeypatch to
 	inspect.findsource(). It can now find source lines inside zipped
 	packages.
 	
 	* IPython/ultraTB.py: When constructing tracebacks, try to use __file__
 	in the frame's namespace before trusting the filename in the code object
 	which created the frame.

 	method to fully stop the logger, along with a corresponding
 	%logstop magic for interactive use.
 
 	* IPython/Extensions/ipy_host_completers.py: added new host
 	completers functionality, contributed by Gael Pasgrimaud
 	<gawel-AT-afpy.org>.
 
 2007-11-24  Fernando Perez  <[e-mail]>
 
 	* IPython/DPyGetOpt.py (ArgumentError): Apply patch by Paul Mueller
 	<gakusei-AT-dakotacom.net>, to fix deprecated string exceptions in
 	options handling.  Unicode fix in %whos (committed a while ago)
 	was also contributed by Paul.
 
 2007-11-23  Darren Dale <[e-mail]>
         * ipy_traits_completer.py: let traits_completer respect the user's
         readline_omit__names setting.
 
 2007-11-08  Ville Vainio  <[e-mail]>
 
 	* ipy_completers.py (import completer): assume 'xml' module exists.
 	Do not add every module twice anymore. Closes #196.
 
 	* ipy_completers.py, ipy_app_completers.py: Add proper apt-get
 	completer that uses apt-cache to search for existing packages.
 
 2007-11-06  Ville Vainio  <[e-mail]>
 
 	* Prompts.py: Do not update _oh and _123 when do_full_cache is not
 	true. Closes #194.
 
 2007-11-01  Brian Granger <[e-mail]>
 
 	* iplib.py, rlineimpl.py: Applied Body Water's patches to get IPython
 	working with OS X 10.5 libedit implementation of readline.
 
 2007-10-24  Ville Vainio  <[e-mail]>
 
 	* iplib.py(user_setup): To route around buggy installations where
 	UserConfig is not available, create a minimal _ipython.
 
 	* iplib.py: Unicode fixes from Jorgen.
 
 	* genutils.py: Slist now has new method 'fields()' for extraction of
 	whitespace-separated fields from line-oriented data.
 
 2007-10-15  Fernando Perez  <[e-mail]>
 
 	* IPython/OInspect.py (Inspector.pinfo): fix bug that could arise
 	when querying objects with no __class__ attribute (such as
 	f2py-generated modules).
 
 2007-10-09  Fernando Perez  <[e-mail]>
 
 	* IPython/Magic.py (magic_time): track compilation time and report
 	it if longer than 0.1s (fix done to %time and %timeit).  After a
 	SAGE bug report: http://trac.sagemath.org/sage_trac/ticket/632.
 
 2007-09-18  Ville Vainio  <[e-mail]>
 
 	* genutils.py(make_quoted_expr): Do not use Itpl, it does
         not support unicode at the moment. Fixes (many) magic calls with
         special characters.
 
 2007-09-14  Fernando Perez  <[e-mail]>
 
 	* IPython/genutils.py (doctest_reload): expose the doctest
 	reloader to the user so that people can easily reset doctest while
 	using it interactively.  Fixes a problem reported by Jorgen.
 
 	* IPython/iplib.py (InteractiveShell.__init__): protect the
 	FakeModule instances used for __main__ in %run calls from
 	deletion, so that user code defined in them isn't left with
 	dangling references due to the Python module deletion machinery.
 	This should fix the problems reported by Darren.
 
 2007-09-10  Darren Dale  <[e-mail]>
 
         * Cleanup of IPShellQt and IPShellQt4
 
 2007-09-09  Fernando Perez  <[e-mail]>
 
 	* IPython/FakeModule.py (FakeModule.__init__): further fixes for
 	doctest support.  
 
 	* IPython/iplib.py (safe_execfile): minor docstring improvements.
 
 2007-09-08  Ville Vainio  <[e-mail]>
 
 	* Magic.py (%pushd, %popd, %dirs): Fix dir stack - push *current*
 	directory, not the target directory.
 
 	* ipapi.py, Magic.py, iplib.py: Add ipapi.UsageError, a lighter weight
 	exception that won't print the tracebacks. Switched many magics to
 	raise them on error situations, also GetoptError is not printed
 	anymore.
 
 2007-09-07  Ville Vainio  <[e-mail]>
 
 	* iplib.py: do not auto-alias "dir", it screws up other dir auto
         aliases.
 
 	* genutils.py: SList.grep() implemented.
         
 	* ipy_editors.py, UserConfig/ipy_user_conf.py: Add some editors
 	for easy "out of the box" setup of several common editors, so that
 	e.g. '%edit os.path.isfile' will jump to the correct line
 	automatically. Contributions for command lines of your favourite
 	editors welcome.
         
 2007-09-07  Fernando Perez  <[e-mail]>
 
 	* IPython/OInspect.py (Inspector.pinfo): fixed bug that was
 	preventing source display in certain cases.  In reality I think
 	the problem is with Ubuntu's Python build, but this change works
 	around the issue in some cases (not in all, unfortunately).  I'd
 	filed a Python bug on this with more details, but in the change of
 	bug trackers it seems to have been lost.
 
 	* IPython/Magic.py (magic_dhist): restore %dhist. No, cd -TAB is
 	not the same, it's not self-documenting, doesn't allow range
 	selection, and sorts alphabetically instead of numerically.
 	(magic_r): restore %r.  No, "up + enter. One char magic" is not
 	the same thing, since %r takes parameters to allow fast retrieval
 	of old commands.  I've received emails from users who use this a
 	LOT, so it stays.
 	(magic_automagic): restore %automagic.  "use _ip.option.automagic"
 	is not a valid replacement b/c it doesn't provide an complete
 	explanation (which the automagic docstring does).
 	(magic_autocall): restore %autocall, with improved docstring.
 	Same argument as for others, "use _ip.options.autocall" is not a
 	valid replacement.
 	(magic_pdef): restore %pdef & friends.  Used widely, mentioned in
 	tutorials and online docs.
 
 2007-09-06  Fernando Perez  <[e-mail]>
 
 	* IPython/usage.py (quick_reference): mention magics in quickref,
 	modified main banner to mention %quickref.
 
 	* IPython/FakeModule.py (FakeModule): fixes for doctest compatibility.
 
 2007-09-06  Ville Vainio  <[e-mail]>
 
 	* ipy_rehashdir.py, ipy_workdir.py, ipy_fsops.py, iplib.py:
 	Callable aliases now pass the _ip as first arg. This breaks 
 	compatibility with earlier 0.8.2.svn series! (though they should
 	not have been in use yet outside these few extensions)
 
 2007-09-05  Ville Vainio  <[e-mail]>
 
 	* external/mglob.py: expand('dirname') => ['dirname'], instead
 	of ['dirname/foo','dirname/bar', ...].
         
 	* Extensions/ipy_fsops.py: added, has usefull shell utils for plain
 	win32 installations: icp, imv, imkdir, igrep, irm, collect (collect
 	is useful for others as well).
 
 	* iplib.py: on callable aliases (as opposed to old style aliases),
 	do var_expand() immediately, and use make_quoted_expr instead
 	of hardcoded r"""
 
 	* Extensions/ipy_profile_sh.py: Try to detect cygwin on win32,
 	if not available load ipy_fsops.py for cp, mv, etc. replacements
 
 	* OInspect.py, ipy_which.py: improve %which and obj? for callable
 	aliases
         
 2007-09-04  Ville Vainio  <[e-mail]>
 
 	* ipy_profile_zope.py: add zope profile, by Stefan Eletzhofer.
 	Relicensed under BSD with the authors approval.
         
 	* ipmaker.py, usage.py: Remove %magic from default banner, improve
 	%quickref        
 
 2007-09-03  Ville Vainio  <[e-mail]>
 
 	* Magic.py: %time now passes expression through prefilter,
 	allowing IPython syntax.
 
 2007-09-01  Ville Vainio  <[e-mail]>
 
 	* ipmaker.py: Always show full traceback when newstyle config fails
 
 2007-08-27  Ville Vainio  <[e-mail]>
 
 	* Magic.py: fix %cd for nonexistent dir when dhist is empty, close #180
 
 2007-08-26  Ville Vainio  <[e-mail]>
 
 	* ipmaker.py: Command line args have the highest priority again
 	
 	* iplib.py, ipmaker.py: -i command line argument now behaves as in
 	normal python, i.e. leaves the IPython session running after -c
 	command or running a batch file from command line.
     
 2007-08-22  Ville Vainio  <[e-mail]>
 
 	* iplib.py: no extra empty (last) line in raw hist w/ multiline
 	statements
 	
 	* logger.py: Fix bug where blank lines in history were not
 	added until AFTER adding the current line; translated and raw
 	history should finally be in sync with prompt now.
 	
 	* ipy_completers.py: quick_completer now makes it easy to create
 	trivial custom completers
 	
 	* clearcmd.py: shadow history compression & erasing, fixed input hist
 	clearing.
 	
 	* envpersist.py, history.py: %env (sh profile only), %hist completers
 	
 	* genutils.py, Prompts.py, Magic.py: win32 - prompt (with \yDEPTH) and
 	term title now include the drive letter, and always use / instead of
 	os.sep (as per recommended approach for win32 ipython in general).
 	
 	* ipykit.py, ipy_kitcfg.py: special launcher for ipykit. Allows running
 	plain python scripts from ipykit command line by running
 	"py myscript.py", even w/o installed python.
 
 2007-08-21  Ville Vainio  <[e-mail]>
 
 	* ipmaker.py: finding ipythonrc-PROF now skips ipy_profile_PROF.
 	(for backwards compatibility)
 	
 	* history.py: switch back to %hist -t from %hist -r as default.
 	At least until raw history is fixed for good.
 
 2007-08-20  Ville Vainio  <[e-mail]>
 
 	* ipapi.py, iplib.py: DebugTools accessible via _ip.dbg, to catch &
 	locate alias redeclarations etc. Also, avoid handling
 	_ip.IP.alias_table directly, prefer using _ip.defalias.
 	
 
 2007-08-15  Ville Vainio  <[e-mail]>
 
 	* prefilter.py: ! is now always served first
 
 2007-08-15  Fernando Perez  <[e-mail]>
 
 	* IPython/iplib.py (safe_execfile): fix the SystemExit
 	auto-suppression code to work in Python2.4 (the internal structure
 	of that exception changed and I'd only tested the code with 2.5).
 	Bug reported by a SciPy attendee.
 
 2007-08-13  Ville Vainio  <[e-mail]>
 
 	* prefilter.py: reverted !c:/bin/foo fix, made % in
         multiline specials work again
 
 2007-08-13  Ville Vainio  <[e-mail]>
 
 	* prefilter.py: Take more care to special-case !, so that
         !c:/bin/foo.exe works.
         
         * setup.py: if we are building eggs, strip all docs and
         examples (it doesn't make sense to bytecompile examples,
         and docs would be in an awkward place anyway).
         
         * Ryan Krauss' patch fixes start menu shortcuts when IPython
         is installed into a directory that has spaces in the name.
 
 2007-08-13  Fernando Perez  <[e-mail]>
 
 	* IPython/Magic.py (magic_doctest_mode): fix prompt separators in
 	doctest profile and %doctest_mode, so they actually generate the
 	blank lines needed by doctest to separate individual tests.
 
 	* IPython/iplib.py (safe_execfile): modify so that running code
 	which calls sys.exit(0) (or equivalently, raise SystemExit(0))
 	doesn't get a printed traceback.  Any other value in sys.exit(),
 	including the empty call, still generates a traceback.  This
 	enables use of %run without having to pass '-e' for codes that
 	correctly set the exit status flag.
 
 2007-08-12  Fernando Perez  <[e-mail]>
 
 	* IPython/iplib.py (InteractiveShell.post_config_initialization):
 	fix problems with doctests failing when run inside IPython due to
 	IPython's modifications of sys.displayhook.
 
 2007-8-9  Fernando Perez  <[e-mail]>
 
         * IPython/ipapi.py (to_user_ns): update to accept a dict as well as
           a string with names.
 
 2007-08-09  Fernando Perez  <[e-mail]>
 
 	* IPython/Magic.py (magic_doctest_mode): added new %doctest_mode
 	magic to toggle on/off the doctest pasting support without having
 	to leave a session to switch to a separate profile.
 
 2007-08-08  Fernando Perez  <[e-mail]>
 
 	* IPython/Extensions/ipy_profile_doctest.py (main): fix prompt to
 	introduce a blank line between inputs, to conform to doctest
 	requirements.
 
 	* IPython/OInspect.py (Inspector.pinfo): fix another part where
 	auto-generated docstrings for new-style classes were showing up.
 
 2007-08-07  Fernando Perez  <[e-mail]>
 
 	* api_changes: Add new file to track backward-incompatible
 	user-visible changes.
 
 2007-08-06  Ville Vainio  <[e-mail]>
 
 	* ipmaker.py: fix bug where user_config_ns didn't exist at all
 	before all the config files were handled.
 
 2007-08-04  Fernando Perez  <[e-mail]>
 
 	* IPython/irunner.py (RunnerFactory): Add new factory class for
 	creating reusable runners based on filenames.
 
 	* IPython/Extensions/ipy_profile_doctest.py: New profile for
 	doctest support.  It sets prompts/exceptions as similar to
 	standard Python as possible, so that ipython sessions in this
 	profile can be easily pasted as doctests with minimal
 	modifications.  It also enables pasting of doctests from external
 	sources (even if they have leading whitespace), so that you can
 	rerun doctests from existing sources.
 
 	* IPython/iplib.py (_prefilter): fix a buglet where after entering
 	some whitespace, the prompt would become a continuation prompt
 	with no way of exiting it other than Ctrl-C.  This fix brings us
 	into conformity with how the default python prompt works.
 
 	* IPython/Extensions/InterpreterPasteInput.py (prefilter_paste):
 	Add support for pasting not only lines that start with '>>>', but
 	also with ' >>>'.  That is, arbitrary whitespace can now precede
 	the prompts.  This makes the system useful for pasting doctests
 	from docstrings back into a normal session.
 
 2007-08-02  Fernando Perez  <[e-mail]>
 
 	* IPython/Shell.py (IPShellEmbed.__call__): fix bug introduced in
 	r1357, which had killed multiple invocations of an embedded
 	ipython (this means that example-embed has been broken for over 1
 	year!!!).  Rather than possibly breaking the batch stuff for which
 	the code in iplib.py/interact was introduced, I worked around the
 	problem in the embedding class in Shell.py.  We really need a
 	bloody test suite for this code, I'm sick of finding stuff that
 	used to work breaking left and right every time I use an old
 	feature I hadn't touched in a few months.
 	(kill_embedded): Add a new magic that only shows up in embedded
 	mode, to allow users to permanently deactivate an embedded instance.
 
 2007-08-01  Ville Vainio  <[e-mail]>
 
 	* iplib.py, ipy_profile_sh.py (runlines): Fix the bug where raw
         history gets out of sync on runlines (e.g. when running macros).
 
 2007-07-31  Fernando Perez  <[e-mail]>
 
 	* IPython/Magic.py (magic_colors): fix win32-related error message
 	that could appear under *nix when readline was missing.  Patch by
 	Scott Jackson, closes #175.
 
 2007-07-29  Fernando Perez  <[e-mail]>
 
 	* IPython/Extensions/ipy_traits_completer.py: Add a new custom
 	completer that it traits-aware, so that traits objects don't show
 	all of their internal attributes all the time.
 
 	* IPython/genutils.py (dir2): moved this code from inside
 	completer.py to expose it publicly, so I could use it in the
 	wildcards bugfix.
 
 	* IPython/wildcard.py (NameSpace.__init__): fix a bug reported by
 	Stefan with Traits.
 
 	* IPython/completer.py (Completer.attr_matches): change internal
 	var name from 'object' to 'obj', since 'object' is now a builtin
 	and this can lead to weird bugs if reusing this code elsewhere.
 
 2007-07-25  Fernando Perez  <[e-mail]>
 
 	* IPython/OInspect.py (Inspector.pinfo): fix small glitches in
 	'foo?' and update the code to prevent printing of default
 	docstrings that started appearing after I added support for
 	new-style classes.  The approach I'm using isn't ideal (I just
 	special-case those strings) but I'm not sure how to more robustly
 	differentiate between truly user-written strings and Python's
 	automatic ones.
 
 2007-07-09  Ville Vainio  <[e-mail]>
 
 	* completer.py: Applied Matthew Neeley's patch:
         Dynamic attributes from trait_names and _getAttributeNames are added
         to the list of tab completions, but when this happens, the attribute
         list is turned into a set, so the attributes are unordered when
         printed, which makes it hard to find the right completion. This patch
         turns this set back into a list and sort it.
 
 2007-07-06  Fernando Perez  <[e-mail]>
 
 	* IPython/OInspect.py (Inspector.pinfo): Add support for new-style
 	classes in various inspector functions.
 
 2007-06-28  Ville Vainio  <[e-mail]>
 
 	* shadowns.py, iplib.py, ipapi.py, OInspect.py:
         Implement "shadow" namespace, and callable aliases that reside there.
         Use them by:
         
         _ip.defalias('foo',myfunc) # creates _sh.foo that points to myfunc
         
         foo hello world
          (gets translated to:)
         _sh.foo(r"""hello world""")
 
         In practice, this kind of alias can take the role of a magic function        
 
         * New generic inspect_object, called on obj? and obj??
 
 2007-06-15  Fernando Perez  <[e-mail]>
 
 	* IPython/ultraTB.py (findsource): fix a problem with
 	inspect.getfile that can cause crashes during traceback construction.
 
 2007-06-14  Ville Vainio  <[e-mail]>
 
 	* iplib.py (handle_auto): Try to use ascii for printing "--->"
         autocall rewrite indication, becausesometimes unicode fails to print
         properly (and you get ' - - - '). Use plain uncoloured ---> for
         unicode.
         
         * shadow history. Usable through "%hist -g <pat>" and "%rep 0123".
         
         . pickleshare 'hash' commands (hget, hset, hcompress,
         hdict) for efficient shadow history storage.
 
 2007-06-13  Ville Vainio  <[e-mail]>
 
 	* ipapi.py: _ip.to_user_ns(vars, interactive = True).
         Added kw arg 'interactive', tell whether vars should be visible
         with %whos.
 
 2007-06-11  Ville Vainio  <[e-mail]>
 
 	* pspersistence.py, Magic.py, iplib.py: directory history now saved 
 	to db
     
 	* iplib.py: "ipython -c <cmd>" now passes the command through prefilter.
 	Also, it exits IPython immediately after evaluating the command (just like 
 	std python)
 
 2007-06-05  Walter Doerwald  <[e-mail]>
 
 	* IPython/Extensions/ipipe.py: Added a new table icap, which executes a
 	Python string and captures the output. (Idea and original patch by
 	Stefan van der Walt)
 
 2007-06-01  Fernando Perez  <[e-mail]>
 
 	* IPython/ultraTB.py (VerboseTB.text): update printing of
 	exception types for Python 2.5 (now all exceptions in the stdlib
 	are new-style classes).
 
 2007-05-31  Walter Doerwald  <[e-mail]>
 
 	* IPython/Extensions/igrid.py: Add new commands refresh and
 	refresh_timer (mapped to "R"/"F5" and to the menu) which restarts
 	the iterator once (refresh) or after every x seconds (refresh_timer).
 	Add a working implementation of "searchexpression", where the text
 	entered is not the text to search for, but an expression that must
 	be true. Added display of shortcuts to the menu. Added commands "pickinput"
 	and "pickinputattr" that put the object or attribute under the cursor
 	in the input line. Split the statusbar to be able to display the currently
 	active refresh interval. (Patch by Nik Tautenhahn)
 
 2007-05-29  Jorgen Stenarson  <[e-mail]>
 	
 	* fixing set_term_title to use ctypes as default
 
 	* fixing set_term_title fallback to work when curent dir 
 	  is on a windows network share
 
 2007-05-28  Ville Vainio  <[e-mail]>
 
 	* %cpaste: strip + with > from left (diffs).
         
         * iplib.py: Fix crash when readline not installed
 
 2007-05-26  Ville Vainio  <[e-mail]>
 
 	* generics.py: introduce easy to extend result_display generic
         function (using simplegeneric.py).
         
         * Fixed the append functionality of %set.
 
 2007-05-25  Ville Vainio  <[e-mail]>
 
 	* New magic: %rep (fetch / run old commands from history)
         
         * New extension: mglob (%mglob magic), for powerful glob / find /filter
         like functionality
         
         % maghistory.py: %hist -g PATTERM greps the history for pattern
 
 2007-05-24  Walter Doerwald  <[e-mail]>
 
 	* IPython/Extensions/ipipe.py: Added a Table ihist that can be used to
 	browse the IPython input history
 
 	* IPython/Extensions/ibrowse.py: Added two command to ibrowse: pickinput
 	(mapped to "i") can be used to put the object under the curser in the input
 	line. pickinputattr (mapped to "I") does the same for the attribute under
 	the cursor.
 
 2007-05-24  Ville Vainio  <[e-mail]>
 
 	* Grand magic cleansing (changeset [2380]):
         
         * Introduce ipy_legacy.py where the following magics were
         moved:
         
         pdef pdoc psource pfile rehash dhist Quit p r automagic autocall
         
         If you need them, either use default profile or "import ipy_legacy"
         in your ipy_user_conf.py
         
         * Move sh and scipy profile to Extensions from UserConfig. this implies
         you should not edit them, but you don't need to run %upgrade when
         upgrading IPython anymore.
         
         * %hist/%history now operates in "raw" mode by default. To get the old
         behaviour, run '%hist -n' (native mode).
         
         * split ipy_stock_completers.py to ipy_stock_completers.py and
         ipy_app_completers.py. Stock completers (%cd, import, %run) are now
         installed as default.
         
         * sh profile now installs ipy_signals.py, for (hopefully) better ctrl+c
         handling.
         
         * iplib.py, ipapi.py: _ip.set_next_input(s) sets the next ("default")
         input if readline is available.
 	
 2007-05-23  Ville Vainio  <[e-mail]>
 
 	* macro.py: %store uses __getstate__ properly
 	
 	* exesetup.py: added new setup script for creating
 	standalone IPython executables with py2exe (i.e.
 	no python installation required).
 	
 	* Removed ipythonrc-scipy, ipy_profile_scipy.py takes
 	its place.
         
         * rlineimpl.py, genutils.py (get_home_dir): py2exe support
 	
 2007-05-21  Ville Vainio  <[e-mail]>
 
 	* platutil_win32.py (set_term_title): handle
 	failure of 'title' system call properly.
 
 2007-05-17  Walter Doerwald  <[e-mail]>
 
 	* IPython/Extensions/ipipe.py: Fix xrepr for ifiles.
 	(Bug detected by Paul Mueller).
 
 2007-05-16  Ville Vainio  <[e-mail]>
 
 	* ipy_profile_sci.py, ipython_win_post_install.py: Create
 	new "sci" profile, effectively a modern version of the old
 	"scipy" profile (which is now slated for deprecation).
 
 2007-05-15  Ville Vainio  <[e-mail]>
 
 	* pycolorize.py, pycolor.1: Paul Mueller's patches that
 	make pycolorize read input from stdin when run without arguments.
 	
 	* Magic.py: do not require 'PATH' in %rehash/%rehashx. Closes #155
 	
 	* ipy_rehashdir.py: rename ext_rehashdir to ipy_rehashdir, import
 	it in sh profile (instead of ipy_system_conf.py).
 
 	* Magic.py, ipy_rehashdir.py, ipy_profile_sh.py: System command
 	aliases are now lower case on windows (MyCommand.exe => mycommand).
 	
 	* macro.py, ipapi.py, iplib.py, Prompts.py: Macro system rehaul.
 	Macros are now callable objects that inherit from ipapi.IPyAutocall,
 	i.e. get autocalled regardless of system autocall setting.
 
 2007-05-10  Fernando Perez  <[e-mail]>
 
 	* IPython/rlineimpl.py: check for clear_history in readline and
 	make it a dummy no-op if not available.  This function isn't
 	guaranteed to be in the API and appeared in Python 2.4, so we need
 	to check it ourselves.  Also, clean up this file quite a bit.
 
 	* ipython.1: update man page and full manual with information
 	about threads (remove outdated warning).  Closes #151.
 
 2007-05-09  Fernando Perez  <[e-mail]>
 
 	* IPython/Extensions/ipy_constants.py: Add Gael's constants module
 	in trunk (note that this made it into the 0.8.1 release already,
 	but the changelogs didn't get coordinated).  Many thanks to Gael
 	Varoquaux <gael.varoquaux-AT-normalesup.org>
 
 2007-05-09  *** Released version 0.8.1
 
 2007-05-10  Walter Doerwald  <[e-mail]>
 
 	* IPython/Extensions/igrid.py: Incorporate html help into
 	the module, so we don't have to search for the file.
 
 2007-05-02  Fernando Perez  <[e-mail]>
 
 	* test/test_irunner.py (RunnerTestCase._test_runner): Close #147.
 
 2007-04-30  Ville Vainio  <[e-mail]>
 
 	* iplib.py: (pre_config_initialization) Catch UnicodeDecodeError if the
 	user has illegal (non-ascii) home directory name
 
 2007-04-27  Ville Vainio  <[e-mail]>
 
 	* platutils_win32.py: implement set_term_title for windows
 	
 	* Update version number
 	
 	* ipy_profile_sh.py: more informative prompt (2 dir levels)
 
 2007-04-26  Walter Doerwald  <[e-mail]>
 
 	* IPython/Extensions/igrid.py: (igrid) Fix bug that surfaced
 	when the igrid input raised an exception. (Patch by Nik Tautenhahn,
 	bug discovered by Ville).
 
 2007-04-26  Ville Vainio  <[e-mail]>
 
 	* Extensions/ipy_completers.py: Olivier's module completer now
 	saves the list of root modules if it takes > 4 secs on the first run.
 	
 	* Magic.py (%rehashx): %rehashx now clears the completer cache
 	
 
 2007-04-26  Fernando Perez  <[e-mail]>
 
 	* ipython.el: fix incorrect color scheme, reported by Stefan.
 	Closes #149.
 
 	* IPython/PyColorize.py (Parser.format2): fix state-handling
 	logic.  I still don't like how that code handles state, but at
 	least now it should be correct, if inelegant.  Closes #146.
 
 2007-04-25  Ville Vainio  <[e-mail]>
 
 	* Extensions/ipy_which.py: added extension for %which magic, works
 	a lot like unix 'which' but also finds and expands aliases, and
 	allows wildcards.
 
 	* ipapi.py (expand_alias): Now actually *return* the expanded alias,
 	as opposed to returning nothing.
 	
 	* UserConfig/ipy_user_conf.py, ipy_profile_sh.py: do not import
 	ipy_stock_completers on default profile, do import on sh profile.
 
 2007-04-22  Jorgen Stenarson  <[e-mail]>
 
 	* Fix bug in iplib.py/safe_execfile when launching ipython with a script
 	like ipython.py foo.py which raised a IndexError.
 
 2007-04-21  Ville Vainio  <[e-mail]>
 
 	* Extensions/ipy_extutil.py: added extension to manage other ipython
 	extensions. Now only supports 'ls' == list extensions.
 
 2007-04-20  Fernando Perez  <[e-mail]>
 
 	* IPython/Debugger.py (BdbQuit_excepthook): fix small bug that
 	would prevent use of the exception system outside of a running
 	IPython instance.
 
 2007-04-20  Ville Vainio  <[e-mail]>
 
 	* Extensions/ipy_render.py: added extension for easy
 	interactive text template rendering (to clipboard). Uses Ka-Ping Yee's
 	'Iptl' template notation, 
 	
 	* Extensions/ipy_completers.py: introduced Olivier Lauzanne's
 	safer & faster 'import' completer.
 	
 	* ipapi.py: Introduced new ipapi methods, _ip.defmacro(name, value)
 	and _ip.defalias(name, command).
 	
 	* Extensions/ipy_exportdb.py: New extension for exporting all the
 	%store'd data in a portable format (normal ipapi calls like
 	defmacro() etc.)
 	
 2007-04-19  Ville Vainio  <[e-mail]>
 
 	* upgrade_dir.py: skip junk files like *.pyc
 	
 	* Release.py: version number to 0.8.1
 
 2007-04-18  Ville Vainio  <[e-mail]>
 
 	* iplib.py (safe_execfile): make "ipython foo.py" work with 2.5.1c1
 	and later on win32.
 
 2007-04-16  Ville Vainio  <[e-mail]>
 
 	* iplib.py (showtraceback): Do not crash when running w/o readline.
 
 2007-04-12  Walter Doerwald  <[e-mail]>
 
 	* IPython/Extensions/ipipe.py: (ils) Directoy listings are now
 	sorted (case sensitive with files and dirs mixed).
 
 2007-04-10  Fernando Perez  <[e-mail]>
 
 	* IPython/Release.py (version): Open trunk for 0.8.1 development.
 
 2007-04-10  *** Released version 0.8.0
 
 2007-04-07  Fernando Perez  <[e-mail]>
 
 	* Tag 0.8.0 for release.
 	
 	* IPython/iplib.py (reloadhist): add API function to cleanly
 	reload the readline history, which was growing inappropriately on
 	every %run call.
 
 	* win32_manual_post_install.py (run): apply last part of Nicolas
 	Pernetty's patch (I'd accidentally applied it in a different
 	directory and this particular file didn't get patched).
 
 2007-04-05  Fernando Perez  <[e-mail]>
 
 	* IPython/Shell.py (MAIN_THREAD_ID): get rid of my stupid hack to
 	find the main thread id and use the proper API call.  Thanks to
 	Stefan for the fix.
 
 	* test/test_prefilter.py (esc_handler_tests): udpate one of Dan's
 	unit tests to reflect fixed ticket #52, and add more tests sent by
 	him.
 
 	* IPython/iplib.py (raw_input): restore the readline completer
 	state on every input, in case third-party code messed it up.
 	(_prefilter): revert recent addition of early-escape checks which
 	prevent many valid alias calls from working.
 
 	* IPython/Shell.py (MTInteractiveShell.runcode): add a tracking
 	flag for sigint handler so we don't run a full signal() call on
 	each runcode access.
 
 	* IPython/Magic.py (magic_whos): small improvement to diagnostic
 	message.
 
 2007-04-04  Fernando Perez  <[e-mail]>
 
 	* IPython/Shell.py (sigint_handler): I *THINK* I finally got
 	asynchronous exceptions working, i.e., Ctrl-C can actually
 	interrupt long-running code in the multithreaded shells.
 
 	This is using Tomer Filiba's great ctypes-based trick:
 	http://sebulba.wikispaces.com/recipe+thread2.  I'd already tried
 	this in the past, but hadn't been able to make it work before.  So
 	far it looks like it's actually running, but this needs more
 	testing.  If it really works, I'll be *very* happy, and we'll owe
 	a huge thank you to Tomer.  My current implementation is ugly,
 	hackish and uses nasty globals, but I don't want to try and clean
 	anything up until we know if it actually works.
 
 	NOTE: this feature needs ctypes to work.  ctypes is included in
 	Python2.5, but 2.4 users will need to manually install it.  This
 	feature makes multi-threaded shells so much more usable that it's
 	a minor price to pay (ctypes is very easy to install, already a
 	requirement for win32 and available in major linux distros).
 
 2007-04-04  Ville Vainio  <[e-mail]>
 
 	* Extensions/ipy_completers.py, ipy_stock_completers.py:
 	Moved implementations of 'bundled' completers to ipy_completers.py,
 	they are only enabled in ipy_stock_completers.py.
 
 2007-04-04  Fernando Perez  <[e-mail]>
 
 	* IPython/PyColorize.py (Parser.format2): Fix identation of
 	colorzied output and return early if color scheme is NoColor, to
 	avoid unnecessary and expensive tokenization.  Closes #131.
 
 2007-04-03  Fernando Perez  <[e-mail]>
 
 	* IPython/Debugger.py: disable the use of pydb version 1.17.  It
 	has a critical bug (a missing import that makes post-mortem not
 	work at all).  Unfortunately as of this time, this is the version
 	shipped with Ubuntu Edgy, so quite a few people have this one.  I
 	hope Edgy will update to a more recent package.
 
 2007-04-02  Fernando Perez  <[e-mail]>
 
 	* IPython/iplib.py (_prefilter): close #52, second part of a patch
 	set by Stefan (only the first part had been applied before).
 
 	* IPython/Extensions/ipy_stock_completers.py (module_completer):
 	remove usage of the dangerous pkgutil.walk_packages().  See
 	details in comments left in the code.
 
 	* IPython/Magic.py (magic_whos): add support for numpy arrays
 	similar to what we had for Numeric.
 
 	* IPython/completer.py (IPCompleter.complete): extend the
 	complete() call API to support completions by other mechanisms
 	than readline.  Closes #109.
 
 	* IPython/iplib.py (safe_execfile): add a safeguard under Win32 to
 	protect against a bug in Python's execfile().  Closes #123.
 
 2007-04-01  Fernando Perez  <[e-mail]>
 
 	* IPython/iplib.py (split_user_input): ensure that when splitting
 	user input, the part that can be treated as a python name is pure
 	ascii (Python identifiers MUST be pure ascii).  Part of the
 	ongoing Unicode support work.
 
 	* IPython/Prompts.py (prompt_specials_color): Add \N for the
 	actual prompt number, without any coloring.  This allows users to
 	produce numbered prompts with their own colors.  Added after a
 	report/request by Thorsten Kampe <thorsten-AT-thorstenkampe.de>.
 
 2007-03-31  Walter Doerwald  <[e-mail]>
 
 	* IPython/Extensions/igrid.py: Map the return key
 	to enter() and shift-return to enterattr().
 
 2007-03-30  Fernando Perez  <[e-mail]>
 
 	* IPython/Magic.py (magic_psearch): add unicode support by
 	encoding to ascii the input, since this routine also only deals
 	with valid Python names.  Fixes a bug reported by Stefan.
 
 2007-03-29  Fernando Perez  <[e-mail]>
 
 	* IPython/Magic.py (_inspect): convert unicode input into ascii
 	before trying to evaluate it as a Python identifier.  This fixes a
 	problem that the new unicode support had introduced when analyzing
 	long definition lines for functions.
 
 2007-03-24  Walter Doerwald  <[e-mail]>
 
 	* IPython/Extensions/igrid.py: Fix picking. Using
 	igrid with wxPython 2.6 and -wthread should work now.
 	igrid.display() simply tries to create a frame without
 	an application. Only if this fails an application is created.
 
 2007-03-23  Walter Doerwald  <[e-mail]>
 
 	* IPython/Extensions/path.py: Updated to version 2.2.
 
 2007-03-23  Ville Vainio  <[e-mail]>
 
 	* iplib.py: recursive alias expansion now works better, so that
 	cases like 'top' -> 'd:/cygwin/top' -> 'ls :/cygwin/top'
 	doesn't trip up the process, if 'd' has been aliased to 'ls'.
 	
 	* Extensions/ipy_gnuglobal.py added, provides %global magic
 	for users of http://www.gnu.org/software/global
 	
 	* iplib.py: '!command /?' now doesn't invoke IPython's help system.
 	Closes #52. Patch by Stefan van der Walt.
 
 2007-03-23  Fernando Perez  <[e-mail]>
 
 	* IPython/FakeModule.py (FakeModule.__init__): Small fix to
 	respect the __file__ attribute when using %run.  Thanks to a bug
 	report by Sebastian Rooks <sebastian.rooks-AT-free.fr>.
 
 2007-03-22  Fernando Perez  <[e-mail]>
 
 	* IPython/iplib.py (raw_input): Fix mishandling of unicode at
 	input.  Patch sent by Stefan.
 
 2007-03-20  Jorgen Stenarson  <[e-mail]>
 	* IPython/Extensions/ipy_stock_completer.py
 	shlex_split, fix bug in shlex_split. len function
 	call was missing an if statement. Caused shlex_split to
 	sometimes return "" as last element.
 
 2007-03-18  Fernando Perez  <[e-mail]>
 
 	* IPython/completer.py
 	(IPCompleter.file_matches.single_dir_expand): fix a problem
 	reported by Stefan, where directories containign a single subdir
 	would be completed too early.
 
 	* IPython/Shell.py (_load_pylab): Make the execution of 'from
 	pylab import *' when -pylab is given be optional.  A new flag,
 	pylab_import_all controls this behavior, the default is True for
 	backwards compatibility.
 
 	* IPython/ultraTB.py (_formatTracebackLines): Added (slightly
 	modified) R. Bernstein's patch for fully syntax highlighted
 	tracebacks.  The functionality is also available under ultraTB for
 	non-ipython users (someone using ultraTB but outside an ipython
 	session).  They can select the color scheme by setting the
 	module-level global DEFAULT_SCHEME.  The highlight functionality
 	also works when debugging.
 
 	* IPython/genutils.py (IOStream.close): small patch by
 	R. Bernstein for improved pydb support.
 
 	* IPython/Debugger.py (Pdb.format_stack_entry): Added patch by
 	DaveS <[e-mail]> to improve support of debugging under
 	NTEmacs, including improved pydb behavior.
 
 	* IPython/Magic.py (magic_prun): Fix saving of profile info for
 	Python 2.5, where the stats object API changed a little.  Thanks
 	to a bug report by Paul Smith <paul.smith-AT-catugmt.com>.
 	
 	* IPython/ColorANSI.py (InputTermColors.Normal): applied Nicolas
 	Pernetty's patch to improve support for (X)Emacs under Win32.
 
 2007-03-17  Fernando Perez  <[e-mail]>
 
 	* IPython/Shell.py (hijack_wx): ipmort WX with current semantics
 	to quiet a deprecation warning that fires with Wx 2.8.  Thanks to
 	a report by Nik Tautenhahn.
 
 2007-03-16  Walter Doerwald  <[e-mail]>
 
 	* setup.py: Add the igrid help files to the list of data files
 	to be installed alongside igrid.
 	* IPython/Extensions/igrid.py: (Patch by Nik Tautenhahn)
 	Show the input object of the igrid browser as the window tile.
 	Show the object the cursor is on in the statusbar.
 
 2007-03-15  Ville Vainio  <[e-mail]>
 
 	* Extensions/ipy_stock_completers.py: Fixed exception
         on mismatching quotes in %run completer. Patch by
         Jorgen Stenarson. Closes #127.
 
 2007-03-14  Ville Vainio  <[e-mail]>
 
 	* Extensions/ext_rehashdir.py: Do not do auto_alias
         in %rehashdir, it clobbers %store'd aliases.
         
         * UserConfig/ipy_profile_sh.py: envpersist.py extension
         (beefed up %env) imported for sh profile.
 
 2007-03-10  Walter Doerwald  <[e-mail]>
 
 	* IPython/Extensions/ipipe.py: Prefer ibrowse over igrid
 	as the default browser.
 	* IPython/Extensions/igrid.py: Make a few igrid attributes private.
 	As igrid displays all attributes it ever encounters, fetch() (which has
 	been renamed to _fetch()) doesn't have to recalculate the display attributes
 	every time a new item is fetched. This should speed up scrolling.
 
 2007-03-10  Fernando Perez  <[e-mail]>
 
 	* IPython/iplib.py (InteractiveShell.__init__): fix for Alex
 	Schmolck's recently reported tab-completion bug (my previous one
 	had a problem).  Patch by Dan Milstein <danmil-AT-comcast.net>.
 
 2007-03-09  Walter Doerwald  <[e-mail]>
 
 	* IPython/Extensions/igrid.py: Patch by Nik Tautenhahn:
 	Close help window if exiting igrid.
 
 2007-03-02  Jorgen Stenarson  <[e-mail]>
 
 	* IPython/Extensions/ipy_defaults.py: Check if readline is available
 	before calling functions from readline.
 
 2007-03-02  Walter Doerwald  <[e-mail]>
 
 	* IPython/Extensions/igrid.py: Add Nik Tautenhahns igrid extension.
 	igrid is a wxPython-based display object for ipipe. If your system has
 	wx installed igrid will be the default display. Without wx ipipe falls
 	back to ibrowse (which needs curses). If no curses is installed ipipe
 	falls back to idump.
 
 2007-03-01  Fernando Perez  <[e-mail]>
 
 	* IPython/iplib.py (split_user_inputBROKEN): temporarily disable
 	my changes from yesterday, they introduced bugs.  Will reactivate
 	once I get a correct solution, which will be much easier thanks to
 	Dan Milstein's new prefilter test suite.
 
 2007-02-28  Fernando Perez  <[e-mail]>
 
 	* IPython/iplib.py (split_user_input): fix input splitting so we
 	don't attempt attribute accesses on things that can't possibly be
 	valid Python attributes.  After a bug report by Alex Schmolck.
 	(InteractiveShell.__init__): brown-paper bag fix; regexp broke
 	%magic with explicit % prefix.
 
 2007-02-27  Fernando Perez  <[e-mail]>
 
 	* IPython/Shell.py (IPShellGTK.mainloop): update threads calls to
 	avoid a DeprecationWarning from GTK.
 
 2007-02-22  Fernando Perez  <[e-mail]>
 
 	* IPython/genutils.py (clock): I modified clock() to return total
 	time, user+system.  This is a more commonly needed metric.  I also
 	introduced the new clocku/clocks to get only user/system time if
 	one wants those instead.
 	
 	***WARNING: API CHANGE*** clock() used to return only user time,
 	so if you want exactly the same results as before, use clocku
 	instead.
 
 2007-02-22  Ville Vainio  <[e-mail]>
 
 	* IPython/Extensions/ipy_p4.py: Extension for improved
         p4 (perforce version control system) experience.
         Adds %p4 magic with p4 command completion and
         automatic -G argument (marshall output as python dict)
 
 2007-02-19  Fernando Perez  <[e-mail]>
 
 	* IPython/demo.py (Demo.re_stop): make dashes optional in demo
 	stop marks. 
 	(ClearingMixin): a simple mixin to easily make a Demo class clear
 	the screen in between blocks and have empty marquees. The
 	ClearDemo and ClearIPDemo classes that use it are included.
 
 2007-02-18  Fernando Perez  <[e-mail]>
 
 	* IPython/irunner.py (pexpect_monkeypatch): patch pexpect to
 	protect against exceptions at Python shutdown time.  Patch
 	sumbmitted to upstream.
 
 2007-02-14  Walter Doerwald  <[e-mail]>
 
 	* IPython/Extensions/ibrowse.py: If entering the first object level
 	(i.e. the object for which the browser has been started) fails,
 	now the error is raised directly (aborting the browser) instead of
 	running into an empty levels list later.
 
 2007-02-03  Walter Doerwald  <[e-mail]>
 
 	* IPython/Extensions/ipipe.py: Add an xrepr implementation
 	for the noitem object.
 
 2007-01-31  Fernando Perez  <[e-mail]>
 
 	* IPython/completer.py (Completer.attr_matches): Fix small
 	tab-completion bug with Enthought Traits objects with units.
 	Thanks to a bug report by Tom Denniston
 	<tom.denniston-AT-alum.dartmouth.org>.
 
 2007-01-27  Fernando Perez  <[e-mail]>
 
 	* IPython/Extensions/ipy_stock_completers.py (runlistpy): fix a
 	bug where only .ipy or .py would be completed.  Once the first
 	argument to %run has been given, all completions are valid because
 	they are the arguments to the script, which may well be non-python
 	filenames.
 
 	* IPython/irunner.py (InteractiveRunner.run_source): major updates
 	to irunner to allow it to correctly support real doctesting of
 	out-of-process ipython code.
 
 	* IPython/Magic.py (magic_cd): Make the setting of the terminal
 	title an option (-noterm_title) because it completely breaks
 	doctesting.
 
 	* IPython/demo.py: fix IPythonDemo class that was not actually working.
 
 2007-01-24  Fernando Perez  <[e-mail]>
 
 	* IPython/irunner.py (main): fix small bug where extensions were
 	not being correctly recognized.
 
 2007-01-23  Walter Doerwald  <[e-mail]>
 
 	* IPython/Extensions/ipipe.py (xiter): Make sure that iterating
 	a string containing a single line yields the string itself as the
 	only item.
 
 	* IPython/Extensions/ibrowse.py (ibrowse): Avoid entering an
 	object if it's the same as the one on the last level (This avoids
 	infinite recursion for one line strings).
 
 2007-01-17  Fernando Perez  <[e-mail]>
 
 	* IPython/ultraTB.py (AutoFormattedTB.__call__): properly flush
 	all output streams before printing tracebacks.  This ensures that
 	user output doesn't end up interleaved with traceback output.
 
 2007-01-10  Ville Vainio  <[e-mail]>
 
 	* Extensions/envpersist.py: Turbocharged %env that remembers
 	env vars across sessions; e.g. "%env PATH+=;/opt/scripts" or
 	"%env VISUAL=jed".
 
 2007-01-05  Fernando Perez  <[e-mail]>
 
 	* IPython/iplib.py (showtraceback): ensure that we correctly call
 	custom handlers in all cases (some with pdb were slipping through,
 	but I'm not exactly sure why).
 
 	* IPython/Debugger.py (Tracer.__init__): added new class to
 	support set_trace-like usage of IPython's enhanced debugger.
 
 2006-12-24  Ville Vainio  <[e-mail]>
 
 	* ipmaker.py: more informative message when ipy_user_conf
 	import fails (suggest running %upgrade).
 	
 	* tools/run_ipy_in_profiler.py: Utility to see where
 	the time during IPython startup is spent.
 	
 2006-12-20  Ville Vainio  <[e-mail]>
 
 	* 0.7.3 is out - merge all from 0.7.3 branch to trunk
 
 	* ipapi.py: Add new ipapi method, expand_alias.
 	
 	* Release.py: Bump up version to 0.7.4.svn
 
 2006-12-17  Ville Vainio  <[e-mail]>
 
 	* Extensions/jobctrl.py: Fixed &cmd arg arg... 
 	to work properly on posix too
 	
 	* Release.py: Update revnum (version is still just 0.7.3).
 
 2006-12-15  Ville Vainio  <[e-mail]>
 
 	* scripts/ipython_win_post_install: create ipython.py in
 	prefix + "/scripts".
 	
 	* Release.py: Update version to 0.7.3.
     
 2006-12-14  Ville Vainio  <[e-mail]>
 
 	* scripts/ipython_win_post_install: Overwrite old shortcuts
 	if they already exist
 
 	* Release.py: release 0.7.3rc2
     
 2006-12-13  Ville Vainio  <[e-mail]>
 
 	* Branch and update Release.py for 0.7.3rc1
 
 2006-12-13  Fernando Perez  <[e-mail]>
 
 	* IPython/Shell.py (IPShellWX): update for current WX naming
 	conventions, to avoid a deprecation warning with current WX
 	versions.  Thanks to a report by Danny Shevitz.
 
 2006-12-12  Ville Vainio  <[e-mail]>
 
 	* ipmaker.py: apply david cournapeau's patch to make
 	import_some work properly even when ipythonrc does 
 	import_some on empty list (it was an old bug!).
 
 	* UserConfig/ipy_user_conf.py, UserConfig/ipythonrc:
 	Add deprecation note to ipythonrc and a url to wiki
 	in ipy_user_conf.py
 
 		 
 	* Magic.py (%run): %run myscript.ipy now runs myscript.ipy
 	as if it was typed on IPython command prompt, i.e.
 	as IPython script.
 	
 	* example-magic.py, magic_grepl.py: remove outdated examples
 
 2006-12-11  Fernando Perez  <[e-mail]>
 
         * IPython/iplib.py (debugger): prevent a nasty traceback if %debug
         is called before any exception has occurred.
 	
 2006-12-08  Ville Vainio  <[e-mail]>
 
 	* Extensions/ipy_stock_completers.py: fix cd completer 
 	to translate /'s to \'s again.
 	
 	* completer.py: prevent traceback on file completions w/ 
 	backslash.
 	
 	* Release.py: Update release number to 0.7.3b3 for release
 
 2006-12-07  Ville Vainio  <[e-mail]>
 
 	* Extensions/ipy_signals.py: Ignore ctrl+C in IPython process
 	while executing external code. Provides more shell-like behaviour
 	and overall better response to ctrl + C / ctrl + break.
 
 	* tools/make_tarball.py: new script to create tarball straight from svn
 	(setup.py sdist doesn't work on win32).
 
 	* Extensions/ipy_stock_completers.py: fix cd completer to give up
 	on dirnames with spaces and use the default completer instead.
 
 	* Revision.py: Change version to 0.7.3b2 for release.
 
 2006-12-05  Ville Vainio  <[e-mail]>
 
 	* Magic.py, iplib.py, completer.py: Apply R. Bernstein's
 	pydb patch 4 (rm debug printing, py 2.5 checking)
 
 2006-11-30  Walter Doerwald  <[e-mail]>
 	* IPython/Extensions/ibrowse.py: Add two new commands to ibrowse:
 	"refresh" (mapped to "r") refreshes the screen by restarting the iterator.
 	"refreshfind" (mapped to "R") does the same but tries to go back to the same
 	object the cursor was on before the refresh. The command "markrange" is
 	mapped to "%" now.
 	* IPython/Extensions/ibrowse.py: Make igrpentry and ipwdentry comparable.
 
 2006-11-29  Fernando Perez  <[e-mail]>
 
 	* IPython/Magic.py (magic_debug): new %debug magic to activate the
 	interactive debugger on the last traceback, without having to call
 	%pdb and rerun your code.  Made minor changes in various modules,
 	should automatically recognize pydb if available.
 
 2006-11-28  Ville Vainio  <[e-mail]>
 
 	* completer.py: If the text start with !, show file completions
 	properly. This helps when trying to complete command name
 	for shell escapes.
 
 2006-11-27  Ville Vainio  <[e-mail]>
 
 	* ipy_stock_completers.py: bzr completer submitted by Stefan van 
 	der Walt. Clean up svn and hg completers by using a common 
 	vcs_completer. 
 	
 2006-11-26  Ville Vainio  <[e-mail]>
 
 	* Remove ipconfig and %config; you should use _ip.options structure
 	directly instead!
 	
 	* genutils.py: add wrap_deprecated function for deprecating callables
 	
 	* iplib.py: deprecate ipmagic, ipsystem, ipalias. Use _ip.magic and
 	_ip.system instead. ipalias is redundant.
 	
 	* Magic.py: %rehashdir no longer aliases 'cmdname' to 'cmdname.exe' on 
 	win32, but just 'cmdname'. Other extensions (non-'exe') are still made 
 	explicit.
 
 	* ipy_stock_completers.py: 'hg' (mercurial VCS) now has a custom 
 	completer. Try it by entering 'hg ' and pressing tab.
 
 	* macro.py: Give Macro a useful __repr__ method
 	
 	* Magic.py: %whos abbreviates the typename of Macro for brevity.
 	
 2006-11-24  Walter Doerwald  <[e-mail]>
 	* IPython/Extensions/astyle.py: Do a relative import of ipipe, so that
 	we don't get a duplicate ipipe module, where registration of the xrepr
 	implementation for Text is useless.
 
 	* IPython/Extensions/ipipe.py: Fix __xrepr__() implementation for ils.
 
 	* IPython/Extensions/ibrowse.py: Fix keymapping for the enter command.
 
 2006-11-24  Ville Vainio  <[e-mail]>
 
 	* Magic.py, manual_base.lyx: Kirill Smelkov patch: 
 	try to use "cProfile" instead of the slower pure python
 	"profile"
 
 2006-11-23  Ville Vainio  <[e-mail]>
 
 	* manual_base.lyx: Kirill Smelkov patch: Fix wrong 
 	Qt+IPython+Designer link in documentation.
 	
 	* Extensions/ipy_pydb.py: R. Bernstein's patch for passing 
 	correct Pdb object to %pydb.
 
 
 2006-11-22  Walter Doerwald  <[e-mail]>
 	* IPython/Extensions/astyle.py: Text needs it's own implemenation of the
 	generic xrepr(), otherwise the list implementation would kick in.
 
 2006-11-21  Ville Vainio  <[e-mail]>
 
 	* upgrade_dir.py: Now actually overwrites a nonmodified user file
 	with one from UserConfig.
 	
 	* ipy_profile_sh.py: Add dummy "depth" to var_expand lambda, 
 	it was missing which broke the sh profile.
 	
 	* completer.py: file completer now uses explicit '/' instead
 	of os.path.join, expansion of 'foo' was broken on win32 
 	if there was one directory with name 'foobar'. 
 
 	* A bunch of patches from Kirill Smelkov:
 	
 	* [patch 9/9] doc: point bug-tracker URL to IPythons trac-tickets.
 
 	* [patch 7/9] Implement %page -r (page in raw mode) - 
 
 	* [patch 5/9] ScientificPython webpage has moved
 
 	* [patch 4/9] The manual mentions %ds, should be %dhist
 
 	* [patch 3/9] Kill old bits from %prun doc.
 
 	* [patch 1/9] Fix typos here and there.
 
 2006-11-08  Ville Vainio  <[e-mail]>
 
 	* completer.py (attr_matches): catch all exceptions raised 
 	by eval of expr with dots.
 
 2006-11-07  Fernando Perez  <[e-mail]>
 
 	* IPython/iplib.py (runsource): Prepend an 'if 1:' to the user
 	input if it starts with whitespace.  This allows you to paste
 	indented input from any editor without manually having to type in
 	the 'if 1:', which is convenient when working interactively.
 	Slightly modifed version of a patch by Bo Peng
 	<bpeng-AT-rice.edu>.
 
 2006-11-03  Fernando Perez  <[e-mail]>
 
 	* IPython/irunner.py (main): modified irunner so it automatically
 	recognizes the right runner to use based on the extension (.py for
 	python, .ipy for ipython and .sage for sage).
 
 	* IPython/iplib.py (InteractiveShell.ipconfig): new builtin, also
 	visible in ipapi as ip.config(), to programatically control the
 	internal rc object.  There's an accompanying %config magic for
 	interactive use, which has been enhanced to match the
 	funtionality in ipconfig.
 
 	* IPython/Magic.py (magic_system_verbose): Change %system_verbose
 	so it's not just a toggle, it now takes an argument.  Add support
 	for a customizable header when making system calls, as the new
 	system_header variable in the ipythonrc file.
 
 2006-11-03  Walter Doerwald  <[e-mail]>
 
 	* IPython/Extensions/ipipe.py: xrepr(), xiter() and xattrs() are now
 	generic functions (using Philip J. Eby's simplegeneric package).
 	This makes it possible to customize the display of third-party classes
 	without having to monkeypatch them. xiter() no longer supports a mode
 	argument and the XMode class has been removed. The same functionality can
 	be implemented via IterAttributeDescriptor and IterMethodDescriptor.
 	One consequence of the switch to generic functions is that xrepr() and
 	xattrs() implementation must define the default value for the mode
 	argument themselves and xattrs() implementations must return real
 	descriptors.
 
 	* IPython/external: This new subpackage will contain all third-party
 	packages that are bundled with IPython. (The first one is simplegeneric).
 
 	* IPython/Extensions/ipipe.py (ifile/ils): Readd output of the parent
 	directory which as been dropped in r1703.
 
 	* IPython/Extensions/ipipe.py (iless): Fixed.
 
 	* IPython/Extensions/ibrowse: Fixed sorting under Python 2.3.
 
 2006-11-03  Fernando Perez  <[e-mail]>
 
 	* IPython/iplib.py (InteractiveShell.var_expand): fix stack
 	handling in variable expansion so that shells and magics recognize
 	function local scopes correctly.  Bug reported by Brian.
 
 	* scripts/ipython: remove the very first entry in sys.path which
 	Python auto-inserts for scripts, so that sys.path under IPython is
 	as similar as possible to that under plain Python.
 
 	* IPython/completer.py (IPCompleter.file_matches): Fix
 	tab-completion so that quotes are not closed unless the completion
 	is unambiguous.  After a request by Stefan.  Minor cleanups in
 	ipy_stock_completers.
 
 2006-11-02  Ville Vainio  <[e-mail]>
 
 	* ipy_stock_completers.py: Add %run and %cd completers.
 	
 	* completer.py: Try running custom completer for both 
 	"foo" and "%foo" if the command is just "foo". Ignore case
 	when filtering possible completions.
 	
 	* UserConfig/ipy_user_conf.py: install stock completers as default	
 	
 	* iplib.py (history_saving_wrapper), debugger(), ipy_pydb.py:
 	simplified readline history save / restore through a wrapper 
 	function
 	
 	
 2006-10-31  Ville Vainio  <[e-mail]>
 
 	* strdispatch.py, completer.py, ipy_stock_completers.py:
 	Allow str_key ("command") in completer hooks. Implement 
 	trivial completer for 'import' (stdlib modules only). Rename 
 	ipy_linux_package_managers.py to ipy_stock_completers.py.
 	SVN completer.
 	
 	* Extensions/ledit.py: %magic line editor for easily and
 	incrementally manipulating lists of strings. The magic command
 	name is %led.
 
 2006-10-30  Ville Vainio  <[e-mail]>
 
 	* Debugger.py, iplib.py (debugger()): Add last set of Rocky 
 	Bernsteins's patches for pydb integration.
 	http://bashdb.sourceforge.net/pydb/
 	
 	* strdispatch.py, iplib.py, completer.py, IPython/__init__.py,
 	Extensions/ipy_linux_package_managers.py, hooks.py: Implement 
 	custom completer hook to allow the users to implement their own 
 	completers. See ipy_linux_package_managers.py for example. The 
 	hook name is 'complete_command'. 
 
 2006-10-28  Fernando Perez  <[e-mail]>
 
 	* IPython/UserConfig/ipythonrc-scipy: minor cleanups to remove old
 	Numeric leftovers.
 
 	* ipython.el (py-execute-region): apply Stefan's patch to fix
 	garbled results if the python shell hasn't been previously started.
 
 	* IPython/genutils.py (arg_split): moved to genutils, since it's a
 	pretty generic function and useful for other things.
 
 	* IPython/OInspect.py (getsource): Add customizable source
 	extractor.  After a request/patch form W. Stein (SAGE).
 
 	* IPython/irunner.py (InteractiveRunner.run_source): reset tty
 	window size to a more reasonable value from what pexpect does,
 	since their choice causes wrapping bugs with long input lines.
 
 2006-10-28  Ville Vainio  <[e-mail]>
 
 	* Magic.py (%run): Save and restore the readline history from 
 	file around %run commands to prevent side effects from 
 	%runned programs that might use readline (e.g. pydb).
 
 	* extensions/ipy_pydb.py: Adds %pydb magic when imported, for 
 	invoking the pydb enhanced debugger.
 
 2006-10-23  Walter Doerwald  <[e-mail]>
 
 	* IPython/Extensions/ipipe.py (ifile): Remove all methods that
 	call the base class method and propagate the return value to
 	ifile. This is now done by path itself.
 
 2006-10-15  Fernando Perez  <[e-mail]>
 
 	* IPython/ipapi.py (IPApi.__init__): Added new entry to public
 	api: set_crash_handler(), to expose the ability to change the
 	internal crash handler.
 
 	* IPython/CrashHandler.py (CrashHandler.__init__): abstract out
 	the various parameters of the crash handler so that apps using
 	IPython as their engine can customize crash handling.  Ipmlemented
 	at the request of SAGE.
 
 2006-10-14  Ville Vainio  <[e-mail]>
 
 	* Magic.py, ipython.el: applied first "safe" part of Rocky 
 	Bernstein's patch set for pydb integration.
 
 	* Magic.py (%unalias, %alias): %store'd aliases can now be
 	removed with '%unalias'. %alias w/o args now shows most 
 	interesting (stored / manually defined) aliases last
 	where they catch the eye w/o scrolling.
 
 	* Magic.py (%rehashx), ext_rehashdir.py: files with
 	'py' extension are always considered executable, even
 	when not in PATHEXT environment variable.
 
 2006-10-12  Ville Vainio  <[e-mail]>
 
 	* jobctrl.py: Add new "jobctrl" extension for spawning background
 	processes with "&find /". 'import jobctrl' to try it out. Requires
 	'subprocess' module, standard in python 2.4+.
 	
 	* iplib.py (expand_aliases, handle_alias): Aliases expand transitively, 
 	so if foo -> bar and bar -> baz, then foo -> baz.
 
 2006-10-09  Fernando Perez  <[e-mail]>
 
 	* IPython/Magic.py (Magic.parse_options): add a new posix option
 	to allow parsing of input args in magics that doesn't strip quotes
 	(if posix=False).  This also closes %timeit bug reported by
 	Stefan.
 
 2006-10-03  Ville Vainio  <[e-mail]>
 
 	* iplib.py (raw_input, interact): Return ValueError catching for 
 	raw_input. Fixes infinite loop for sys.stdin.close() or 
 	sys.stdout.close().
 
 2006-09-27  Fernando Perez  <[e-mail]>
 
 	* IPython/irunner.py (InteractiveRunner.run_source): small fixes
 	to help in handling doctests.  irunner is now pretty useful for
 	running standalone scripts and simulate a full interactive session
 	in a format that can be then pasted as a doctest.
 
 	* IPython/iplib.py (InteractiveShell.__init__): Install exit/quit
 	on top of the default (useless) ones.  This also fixes the nasty
 	way in which 2.5's Quitter() exits (reverted [1785]).
 
 	* IPython/Debugger.py (Pdb.__init__): Fix ipdb to work with python
 	2.5.
 
 	* IPython/ultraTB.py (TBTools.set_colors): Make sure that ipdb
 	color scheme is updated as well when color scheme is changed
 	interactively. 
 
 2006-09-27  Ville Vainio  <[e-mail]>
 
 	* iplib.py (raw_input): python 2.5 closes stdin on quit -> avoid
     infinite loop and just exit. It's a hack, but will do for a while.
 
 2006-08-25  Walter Doerwald  <[e-mail]>
 
 	* IPython/Extensions/ipipe.py (ils): Add arguments dirs and files to
 	the constructor, this makes it possible to get a list of only directories
 	or only files.
 
 2006-08-12  Ville Vainio  <[e-mail]>
 
 	* Fakemodule.py, OInspect.py: Reverted 2006-08-11 mods,
 	they broke unittest 
 
 2006-08-11  Ville Vainio  <[e-mail]>
 
 	* Fakemodule.py, OInspect.py: remove 2006-08-09 monkepatch
 	by resolving issue properly, i.e. by inheriting FakeModule
 	from types.ModuleType. Pickling ipython interactive data
 	should still work as usual (testing appreciated).
 
 2006-08-09  Fernando Perez  <[e-mail]>
 
 	* IPython/OInspect.py: monkeypatch inspect from the stdlib if
 	running under python 2.3 with code from 2.4 to fix a bug with
 	help().  Reported by the Debian maintainers, Norbert Tretkowski
 	<norbert-AT-tretkowski.de> and Alexandre Fayolle
 	<afayolle-AT-debian.org>.
 
 2006-08-04  Walter Doerwald  <[e-mail]>
 
 	* IPython/Extensions/ibrowse.py: Fixed the help message in the footer
 	(which was displaying "quit" twice).
 
 2006-07-28  Walter Doerwald  <[e-mail]>
 
 	* IPython/Extensions/ipipe.py: Fix isort.__iter__() (was still using
 	the mode argument).
 
 2006-07-27  Walter Doerwald  <[e-mail]>
 
 	* IPython/Extensions/ipipe.py: Fix getglobals() if we're
 	not running under IPython.
 
 	* IPython/Extensions/ipipe.py: Rename XAttr to AttributeDetail
 	and make it iterable (iterating over the attribute itself). Add two new
 	magic strings for __xattrs__(): If the string starts with "-", the attribute
 	will not be displayed in ibrowse's detail view (but it can still be
 	iterated over). This makes it possible to add attributes that are large
 	lists or generator methods to the detail view. Replace magic attribute names
 	and _attrname() and _getattr() with "descriptors": For each type of magic
 	attribute name there's a subclass of Descriptor: None -> SelfDescriptor();
 	"foo" -> AttributeDescriptor("foo"); "foo()" -> MethodDescriptor("foo");
 	"-foo" -> IterAttributeDescriptor("foo"); "-foo()" -> IterMethodDescriptor("foo");
 	foo() -> FunctionDescriptor(foo). Magic strings returned from __xattrs__()
 	are still supported.
 
 	* IPython/Extensions/ibrowse.py: If fetching the next row from the input
 	fails in ibrowse.fetch(), the exception object is added as the last item
 	and item fetching is canceled. This prevents ibrowse from aborting if e.g.
 	a generator throws an exception midway through execution.
 
 	* IPython/Extensions/ipipe.py: Turn ifile's properties mimetype and
 	encoding into methods.
 
 2006-07-26  Ville Vainio  <[e-mail]>
 
 	* iplib.py: history now stores multiline input as single
 	history entries. Patch by Jorgen Cederlof.
 
 2006-07-18  Walter Doerwald  <[e-mail]>
 
 	* IPython/Extensions/ibrowse.py: Make cursor visible over
 	non existing attributes.
 
 2006-07-14  Walter Doerwald  <[e-mail]>
 
 	* IPython/Extensions/ipipe.py (ix): Use os.popen4() so that the
 	error output of the running command doesn't mess up the screen.
 
 2006-07-13  Walter Doerwald  <[e-mail]>
 
 	* IPython/Extensions/ipipe.py (isort): Make isort usable without
 	argument. This sorts the items themselves.
 
 2006-07-12  Walter Doerwald  <[e-mail]>
 
 	* IPython/Extensions/ipipe.py (eval, ifilter, isort, ieval):
 	Compile expression strings into code objects. This should speed
 	up ifilter and friends somewhat.
 
 2006-07-08  Ville Vainio  <[e-mail]>
 
 	* Magic.py: %cpaste now strips > from the beginning of lines
 	to ease pasting quoted code from emails. Contributed by 
 	Stefan van der Walt.
 
 2006-06-29  Ville Vainio  <[e-mail]>
 
 	* ipmaker.py, Shell.py: qt4agg matplotlib backend support for pylab
 	mode, patch contributed by Darren Dale. NEEDS TESTING! 
 
 2006-06-28  Walter Doerwald  <[e-mail]>
 
 	* IPython/Extensions/ibrowse.py: Give the ibrowse cursor row
 	a blue background. Fix fetching new display rows when the browser
 	scrolls more than a screenful (e.g. by using the goto command).
 
 2006-06-27  Ville Vainio  <[e-mail]>
 
 	* Magic.py (_inspect, _ofind) Apply David Huard's 
 	patch for displaying the correct docstring for 'property' 
 	attributes.
 
 2006-06-23  Walter Doerwald  <[e-mail]>
 
 	* IPython/Extensions/ibrowse.py: Put the documentation of the keyboard
 	commands into the methods implementing them.
 
 2006-06-22  Fernando Perez  <[e-mail]>
 
 	* ipython.el (ipython-indentation-hook): cleanup patch, submitted
 	by Kov Chai <tchaikov-AT-gmail.com>.  He notes that the original
 	autoindent support was authored by Jin Liu.
 
 2006-06-22  Walter Doerwald  <[e-mail]>
 
 	* IPython/Extensions/ibrowse.py: Replace the plain dictionaries used
 	for keymaps with a custom class that simplifies handling.
 
 2006-06-19  Walter Doerwald  <[e-mail]>
 
 	* IPython/Extensions/ibrowse.py: ibrowse now properly handles terminal
 	resizing. This requires Python 2.5 to work.
 
 2006-06-16  Walter Doerwald  <[e-mail]>
 
 	* IPython/Extensions/ibrowse.py: Add two new commands to
 	ibrowse: "hideattr" (mapped to "h") hides the attribute under
 	the cursor. "unhiderattrs" (mapped to "H") reveals all hidden
 	attributes again. Remapped the help command to "?". Display
 	keycodes in the range 0x01-0x1F as CTRL-xx. Add CTRL-a and CTRL-e
 	as keys for the "home" and "end" commands. Add three new commands
 	to the input mode for "find" and friends: "delend" (CTRL-K)
 	deletes to the end of line. "incsearchup" searches upwards in the
 	command history for an input that starts with the text before the cursor.
 	"incsearchdown" does the same downwards. Removed a bogus mapping of
 	the x key to "delete".
 
 2006-06-15  Ville Vainio  <[e-mail]>
 
 	* iplib.py, hooks.py: Added new generate_prompt hook that can be
 	used to create prompts dynamically, instead of the "old" way of
 	assigning "magic" strings to prompt_in1 and prompt_in2. The old
 	way still works (it's invoked by the default hook), of course.
 	
 	* Prompts.py: added generate_output_prompt hook for altering output
 	prompt
 
 	* Release.py: Changed version string to 0.7.3.svn.
 	
 2006-06-15  Walter Doerwald  <[e-mail]>
 
 	* IPython/Extensions/ibrowse.py: Change _BrowserLevel.moveto() so that
 	the call to fetch() always tries to fetch enough data for at least one
 	full screen. This makes it possible to simply call moveto(0,0,True) in
 	the constructor. Fix typos and removed the obsolete goto attribute.
 
 2006-06-12  Ville Vainio  <[e-mail]>
 
 	* ipy_profile_sh.py: applied Krisha Mohan Gundu's patch for
 	allowing $variable interpolation within multiline statements,
 	though so far only with "sh" profile for a testing period.
 	The patch also enables splitting long commands with \ but it
 	doesn't work properly yet.
 
 2006-06-12  Walter Doerwald  <[e-mail]>
 
 	* IPython/Extensions/ibrowse.py (_dodisplay): Display the length of the
 	input history and the position of the cursor in the input history for
 	the find, findbackwards and goto command.
 
 2006-06-10  Walter Doerwald  <[e-mail]>
 
 	* IPython/Extensions/ibrowse.py: Add a class _CommandInput that
 	implements the basic functionality of browser commands that require
 	input. Reimplement the goto, find and findbackwards commands as
 	subclasses of _CommandInput. Add an input history and keymaps to those
 	commands. Add "\r" as a keyboard shortcut for the enterdefault and
 	execute commands.
 
 2006-06-07  Ville Vainio  <[e-mail]>
 
 	* iplib.py: ipython mybatch.ipy exits ipython immediately after
 	running the batch files instead of leaving the session open.
 
 2006-06-07  Fernando Perez  <[e-mail]>
 
 	* IPython/iplib.py (InteractiveShell.__init__): update BSD fix, as
 	the original fix was incomplete.  Patch submitted by W. Maier.
 
 2006-06-07  Ville Vainio  <[e-mail]>
 
 	* iplib.py,Magic.py, ipmaker.py (magic_rehashx):
 	Confirmation prompts can be supressed by 'quiet' option.
 	_ip.options.quiet = 1 means "assume yes for all yes/no queries".
 
 2006-06-06  *** Released version 0.7.2
 
 2006-06-06  Fernando Perez  <[e-mail]>
 
 	* IPython/Release.py (version): Made 0.7.2 final for release.
 	Repo tagged and release cut.
 
 2006-06-05  Ville Vainio  <[e-mail]>
 
 	* Magic.py (magic_rehashx): Honor no_alias list earlier in
 	%rehashx, to avoid clobbering builtins in ipy_profile_sh.py
 	
 	* upgrade_dir.py: try import 'path' module a bit harder
 	(for %upgrade)
 
 2006-06-03  Fernando Perez  <[e-mail]>
 
 	* IPython/genutils.py (ask_yes_no): treat EOF as a default answer
 	instead of looping 20 times.
 
 	* IPython/ipmaker.py (make_IPython): honor -ipythondir flag
 	correctly at initialization time.  Bug reported by Krishna Mohan
 	Gundu <gkmohan-AT-gmail.com> on the user list.
 
 	* IPython/Release.py (version): Mark 0.7.2 version to start
 	testing for release on 06/06.
 
 2006-05-31  Fernando Perez  <[e-mail]>
 
 	* scripts/irunner: thin script interface so users don't have to
 	find the module and call it as an executable, since modules rarely
 	live in people's PATH.
 
 	* IPython/irunner.py (InteractiveRunner.__init__): added
 	delaybeforesend attribute to control delays with newer versions of
 	pexpect.  Thanks to detailed help from pexpect's author, Noah
 	Spurrier <noah-AT-noah.org>.  Noted how to use the SAGE runner
 	correctly (it works in NoColor mode).
 
 	* IPython/iplib.py (handle_normal): fix nasty crash reported on
 	SAGE list, from improper log() calls.
 
 2006-05-31  Ville Vainio  <[e-mail]>
 
 	* upgrade_dir.py, Magic.py (magic_upgrade): call upgrade_dir
 	with args in parens to work correctly with dirs that have spaces.
 
 2006-05-30  Fernando Perez  <[e-mail]>
 
 	* IPython/Logger.py (Logger.logstart): add option to log raw input
 	instead of the processed one.  A -r flag was added to the
 	%logstart magic used for controlling logging.
 
 2006-05-29  Fernando Perez  <[e-mail]>
 
 	* IPython/iplib.py (InteractiveShell.__init__): add check for the
 	*BSDs to omit --color from all 'ls' aliases, since *BSD ls doesn't
 	recognize the option.  After a bug report by Will Maier.  This
 	closes #64 (will do it after confirmation from W. Maier).
 
 	* IPython/irunner.py: New module to run scripts as if manually
 	typed into an interactive environment, based on pexpect.  After a
 	submission by Ken Schutte <kschutte-AT-csail.mit.edu> on the
 	ipython-user list.  Simple unittests in the tests/ directory.
 
 	* tools/release: add Will Maier, OpenBSD port maintainer, to
 	recepients list.  We are now officially part of the OpenBSD ports:
 	http://www.openbsd.org/ports.html !  Many thanks to Will for the
 	work.
 
 2006-05-26  Fernando Perez  <[e-mail]>
 
 	* IPython/ipmaker.py (make_IPython): modify sys.argv fix (below)
 	so that it doesn't break tkinter apps.
 	
 	* IPython/iplib.py (_prefilter): fix bug where aliases would
 	shadow variables when autocall was fully off.  Reported by SAGE
 	author William Stein.
 
 	* IPython/OInspect.py (Inspector.__init__): add a flag to control
 	at what detail level strings are computed when foo? is requested.
 	This allows users to ask for example that the string form of an
 	object is only computed when foo?? is called, or even never, by
 	setting the object_info_string_level >= 2 in the configuration
 	file.  This new option has been added and documented.  After a
 	request by SAGE to be able to control the printing of very large
 	objects more easily.
 
 2006-05-25  Fernando Perez  <[e-mail]>
 
 	* IPython/ipmaker.py (make_IPython): remove the ipython call path
 	from sys.argv, to be 100% consistent with how Python itself works
 	(as seen for example with python -i file.py).  After a bug report
 	by Jeffrey Collins.
 
 	* IPython/Shell.py (MatplotlibShellBase._matplotlib_config): Fix
 	nasty bug which was preventing custom namespaces with -pylab,
 	reported by M. Foord.  Minor cleanup, remove old matplotlib.matlab
 	compatibility (long gone from mpl).
 
 	* IPython/ipapi.py (make_session): name change: create->make.  We
 	use make in other places (ipmaker,...), it's shorter and easier to
 	type and say, etc.  I'm trying to clean things before 0.7.2 so
 	that I can keep things stable wrt to ipapi in the chainsaw branch.
 
 	* ipython.el: fix the py-pdbtrack-input-prompt variable so that
 	python-mode recognizes our debugger mode.  Add support for
 	autoindent inside (X)emacs.  After a patch sent in by Jin Liu
 	<m.liu.jin-AT-gmail.com> originally written by
 	doxgen-AT-newsmth.net (with minor modifications for xemacs
 	compatibility)
 
 	* IPython/Debugger.py (Pdb.format_stack_entry): fix formatting of
 	tracebacks when walking the stack so that the stack tracking system
 	in emacs' python-mode can identify the frames correctly.
 
 	* IPython/ipmaker.py (make_IPython): make the internal (and
 	default config) autoedit_syntax value false by default.  Too many
 	users have complained to me (both on and off-list) about problems
 	with this option being on by default, so I'm making it default to
 	off.  It can still be enabled by anyone via the usual mechanisms.
 
 	* IPython/completer.py (Completer.attr_matches): add support for
 	PyCrust-style _getAttributeNames magic method.  Patch contributed
 	by <mscott-AT-goldenspud.com>.  Closes #50.
 
 	* IPython/iplib.py (InteractiveShell.__init__): remove the
 	deletion of exit/quit from __builtin__, which can break
 	third-party tools like the Zope debugging console.  The
 	%exit/%quit magics remain.  In general, it's probably a good idea
 	not to delete anything from __builtin__, since we never know what
 	that will break.  In any case, python now (for 2.5) will support
 	'real' exit/quit, so this issue is moot.  Closes #55.
 
 	* IPython/genutils.py (with_obj): rename the 'with' function to
 	'withobj' to avoid incompatibilities with Python 2.5, where 'with'
 	becomes a language keyword.  Closes #53.
 
 	* IPython/FakeModule.py (FakeModule.__init__): add a proper
 	__file__ attribute to this so it fools more things into thinking
 	it is a real module.  Closes #59.
 
 	* IPython/Magic.py (magic_edit): add -n option to open the editor
 	at a specific line number.  After a patch by Stefan van der Walt.
 
 2006-05-23  Fernando Perez  <[e-mail]>
 
 	* IPython/iplib.py (edit_syntax_error): fix crash when for some
 	reason the file could not be opened.  After automatic crash
 	reports sent by James Graham <jgraham-AT-ast.cam.ac.uk> and
 	Charles Dolan <charlespatrickdolan-AT-yahoo.com>.
 	(_should_recompile): Don't fire editor if using %bg, since there
 	is no file in the first place.  From the same report as above.
 	(raw_input): protect against faulty third-party prefilters.  After
 	an automatic crash report sent by Dirk Laurie <dirk-AT-sun.ac.za>
 	while running under SAGE.
 
 2006-05-23  Ville Vainio  <[e-mail]>
 
 	* ipapi.py: Stripped down ip.to_user_ns() to work only as
 	ip.to_user_ns("x1 y1"), which exposes vars x1 and y1. ipapi.get()
 	now returns None (again), unless dummy is specifically allowed by
 	ipapi.get(allow_dummy=True).
 
 2006-05-18  Fernando Perez  <[e-mail]>
 
 	* IPython: remove all 2.2-compatibility objects and hacks from
 	everywhere, since we only support 2.3 at this point.  Docs
 	updated.
 
 	* IPython/ipapi.py (IPApi.__init__): Cleanup of all getters.
 	Anything requiring extra validation can be turned into a Python
 	property in the future.  I used a property for the db one b/c
 	there was a nasty circularity problem with the initialization
 	order, which right now I don't have time to clean up.
 
 	* IPython/Shell.py (MTInteractiveShell.runcode): Fix, I think,
 	another locking bug reported by Jorgen.  I'm not 100% sure though,
 	so more testing is needed...
 
 2006-05-17  Fernando Perez  <[e-mail]>
 
 	* IPython/ipapi.py (IPApi.to_user_ns): New function to inject
 	local variables from any routine in user code (typically executed
 	with %run) directly into the interactive namespace.  Very useful
 	when doing complex debugging.
 	(IPythonNotRunning): Changed the default None object to a dummy
 	whose attributes can be queried as well as called without
 	exploding, to ease writing code which works transparently both in
 	and out of ipython and uses some of this API.
 
 2006-05-16  Fernando Perez  <[e-mail]>
 
 	* IPython/hooks.py (result_display): Fix the fact that our display
 	hook was using str() instead of repr(), as the default python
 	console does.  This had gone unnoticed b/c it only happened if
 	%Pprint was off, but the inconsistency was there.
 
 2006-05-15  Ville Vainio  <[e-mail]>
 
 	* Oinspect.py: Only show docstring for nonexisting/binary files
 	when doing object??, closing ticket #62
 
 2006-05-13  Fernando Perez  <[e-mail]>
 
 	* IPython/Shell.py (MTInteractiveShell.runsource): Fix threading
 	bug, closes http://www.scipy.net/roundup/ipython/issue55.  A lock
 	was being released in a routine which hadn't checked if it had
 	been the one to acquire it.
 
 2006-05-07  Fernando Perez  <[e-mail]>
 
 	* IPython/Release.py (version): put out 0.7.2.rc1 for testing.
 
 2006-04-11  Ville Vainio  <[e-mail]>
 
 	* iplib.py, ipmaker.py: .ipy extension now means "ipython batch file"
 	in command line. E.g. "ipython test.ipy" runs test.ipy with ipython
 	prefilters, allowing stuff like magics and aliases in the file.
 	
 	* Prompts.py, Extensions/clearcmd.py, ipy_system_conf.py: %clear magic
 	added. Supported now are "%clear in" and "%clear out" (clear input and
 	output history, respectively). Also fixed CachedOutput.flush to
 	properly flush the output cache.
 	
 	* Extensions/pspersistence.py: Fix %store to avoid "%store obj.attr"
 	half-success (and fail explicitly).
 
 2006-03-28  Ville Vainio  <[e-mail]>
 
 	* iplib.py: Fix quoting of aliases so that only argless ones
 	are quoted
 
 2006-03-28  Ville Vainio  <[e-mail]>
 
 	* iplib.py: Quote aliases with spaces in the name.
 	"c:\program files\blah\bin" is now legal alias target.
 	
 	* ext_rehashdir.py: Space no longer allowed as arg
 	separator, since space is legal in path names.
 	
 2006-03-16  Ville Vainio  <[e-mail]>
 
 	* upgrade_dir.py: Take path.py from Extensions, correcting
 	%upgrade magic
 	
 	* ipmaker.py: Suggest using %upgrade if ipy_user_conf.py isn't found.
 	
 	* hooks.py: Only enclose editor binary in quotes if legal and
 	necessary (space in the name, and is an existing file). Fixes a bug
 	reported by Zachary Pincus.
 
 2006-03-13  Fernando Perez  <[e-mail]>
 
 	* Manual: thanks to a tip on proper color handling for Emacs, by
 	Eric J Haywiser <ejh1-AT-MIT.EDU>.
 	
 	* ipython.el: close http://www.scipy.net/roundup/ipython/issue57
 	by applying the provided patch.  Thanks to Liu Jin
 	<m.liu.jin-AT-gmail.com> for the contribution.  No problems under
 	XEmacs/Linux, I'm trusting the submitter that it actually helps
 	under win32/GNU Emacs.  Will revisit if any problems are reported.
 
 2006-03-12  Fernando Perez  <[e-mail]>
 
 	* IPython/Gnuplot2.py (_FileClass): update for current Gnuplot.py
 	from SVN, thanks to a patch by Ryan Woodard <[e-mail]>.
 
 2006-03-12  Ville Vainio  <[e-mail]>
 
 	* Magic.py (magic_timeit): Added %timeit magic, contributed by
 	Torsten Marek.
 
 2006-03-12  Fernando Perez  <[e-mail]>
 
 	* IPython/Magic.py (magic_macro): fix so that the n1-n2 syntax for
 	line ranges works again.
 
 2006-03-11  Fernando Perez  <[e-mail]>
 
 	* IPython/iplib.py (showtraceback): add back sys.last_traceback
 	and friends, after a discussion with Zach Pincus on ipython-user.
 	I'm not 100% sure, but after thinking about it quite a bit, it may
 	be OK.  Testing with the multithreaded shells didn't reveal any
 	problems, but let's keep an eye out.
 
 	In the process, I fixed a few things which were calling
 	self.InteractiveTB() directly (like safe_execfile), which is a
 	mistake: ALL exception reporting should be done by calling
 	self.showtraceback(), which handles state and tab-completion and
 	more.
 
 2006-03-01  Ville Vainio  <[e-mail]>
 
 	* Extensions/ipipe.py: Added Walter Doerwald's "ipipe" module.
 	To use, do "from ipipe import *".
 
 2006-02-24  Ville Vainio  <[e-mail]>
 
 	* Magic.py, upgrade_dir.py: %upgrade magic added. Does things more
 	"cleanly" and safely than the older upgrade mechanism.
 
 2006-02-21  Ville Vainio  <[e-mail]>
 
 	* Magic.py: %save works again.
 
 2006-02-15  Ville Vainio  <[e-mail]>
 
 	* Magic.py: %Pprint works again
 	
 	* Extensions/ipy_sane_defaults.py: Provide everything provided
 	in default ipythonrc, to make it possible to have a completely empty
 	ipythonrc (and thus completely rc-file free configuration)
 
 2006-02-11  Fernando Perez  <[e-mail]>
 
 	* IPython/hooks.py (editor): quote the call to the editor command,
 	to allow commands with spaces in them.  Problem noted by watching
 	Ian Oswald's video about textpad under win32 at
 	http://showmedo.com/videoListPage?listKey=PythonIPythonSeries
 
 	* IPython/UserConfig/ipythonrc: Replace @ signs with % when
 	describing magics (we haven't used @ for a loong time).
 
 	* IPython/ultraTB.py (VerboseTB.text.text_repr): Added patch
 	contributed by marienz to close
 	http://www.scipy.net/roundup/ipython/issue53.
 
 2006-02-10  Ville Vainio  <[e-mail]>
 
 	* genutils.py: getoutput now works in win32 too
 	
 	* completer.py: alias and magic completion only invoked
 	at the first "item" in the line, to avoid "cd %store"
 	nonsense.
 	
 2006-02-09  Ville Vainio  <[e-mail]>
 
 	* test/*: Added a unit testing framework (finally).
 	'%run runtests.py' to run test_*.
 	
 	* ipapi.py: Exposed runlines and set_custom_exc
 
 2006-02-07  Ville Vainio  <[e-mail]>
 
 	* iplib.py: don't split "f 1 2" to "f(1,2)" in autocall,
 	instead use "f(1 2)" as before.
 
 2006-02-05  Fernando Perez  <[e-mail]>
 
 	* IPython/demo.py (IPythonDemo): Add new classes to the demo
 	facilities, for demos processed by the IPython input filter
 	(IPythonDemo), and for running a script one-line-at-a-time as a
 	demo, both for pure Python (LineDemo) and for IPython-processed
 	input (IPythonLineDemo).  After a request by Dave Kohel, from the
 	SAGE team.
 	(Demo.edit): added an edit() method to the demo objects, to edit
 	the in-memory copy of the last executed block.
 
 	* IPython/Magic.py (magic_edit): add '-r' option for 'raw'
 	processing to %edit, %macro and %save.  These commands can now be
 	invoked on the unprocessed input as it was typed by the user
 	(without any prefilters applied).  After requests by the SAGE team
 	at SAGE days 2006: http://modular.ucsd.edu/sage/days1/schedule.html.
 
 2006-02-01  Ville Vainio  <[e-mail]>
 
 	* setup.py, eggsetup.py: easy_install ipython==dev works
 	correctly now (on Linux)
 	
 	* ipy_user_conf,ipmaker: user config changes, removed spurious
 	warnings
 	
 	* iplib: if rc.banner is string, use it as is.
 	
 	* Magic: %pycat accepts a string argument and pages it's contents.
 
 
 2006-01-30  Ville Vainio  <[e-mail]>
 
 	* pickleshare,pspersistence,ipapi,Magic: persistence overhaul.
 	Now %store and bookmarks work through PickleShare, meaning that
 	concurrent access is possible and all ipython sessions see the
 	same database situation all the time, instead of snapshot of
 	the situation when the session was started. Hence, %bookmark
 	results are immediately accessible from othes sessions. The database
 	is also available for use by user extensions. See:
 	http://www.python.org/pypi/pickleshare
 	
 	* hooks.py: Two new hooks, 'shutdown_hook' and 'late_startup_hook'.
 	
 	* aliases can now be %store'd
 	
 	* path.py moved to Extensions so that pickleshare does not need
 	IPython-specific import. Extensions added to pythonpath right
 	at __init__.
 	
 	* iplib.py: ipalias deprecated/redundant; aliases are converted and
 	called with _ip.system and the pre-transformed command string.
 
 2006-01-29  Fernando Perez  <[e-mail]>
 
 	* IPython/iplib.py (interact): Fix that we were not catching
 	KeyboardInterrupt exceptions properly.  I'm not quite sure why the
 	logic here had to change, but it's fixed now.
 
 2006-01-29  Ville Vainio  <[e-mail]>
 
 	* iplib.py: Try to import pyreadline on Windows.
 
 2006-01-27  Ville Vainio  <[e-mail]>
 
 	* iplib.py: Expose ipapi as _ip in builtin namespace.
 	Makes ipmagic (-> _ip.magic), ipsystem (-> _ip.system)
 	and ip_set_hook (-> _ip.set_hook) redundant. % and !
 	syntax now produce _ip.* variant of the commands.
 	
 	* "_ip.options().autoedit_syntax = 2" automatically throws
 	user to editor for syntax error correction without prompting.
 
 2006-01-27  Ville Vainio  <[e-mail]>
 
 	* ipmaker.py: Give "realistic" sys.argv for scripts (without
 	'ipython' at argv[0]) executed through command line.
 	NOTE: this DEPRECATES calling ipython with multiple scripts
 	("ipython a.py b.py c.py")
 	
 	* iplib.py, hooks.py: Added configurable input prefilter,
 	named 'input_prefilter'. See ext_rescapture.py for example
 	usage.
 	
 	* ext_rescapture.py, Magic.py: Better system command output capture
 	through 'var = !ls' (deprecates user-visible %sc). Same notation
 	applies for magics, 'var = %alias' assigns alias list to var.
 	
 	* ipapi.py: added meta() for accessing extension-usable data store.
 	
 	* iplib.py: added InteractiveShell.getapi(). New magics should be
 	written doing self.getapi() instead of using the shell directly.
 	
 	* Magic.py: %store now allows doing %store foo > ~/myfoo.txt and
 	%store foo >> ~/myfoo.txt to store variables to files (in clean
 	textual form, not a restorable pickle).
 	
 	* ipmaker.py: now import ipy_profile_PROFILENAME automatically
 	
 	* usage.py, Magic.py: added %quickref
 	
 	* iplib.py: ESC_PAREN fixes: /f 1 2 -> f(1,2), not f(1 2).
 	
 	* GetoptErrors when invoking magics etc. with wrong args
 	are now more helpful:
 	GetoptError: option -l not recognized (allowed: "qb" )
 
 2006-01-25  Fernando Perez  <[e-mail]>
 
 	* IPython/demo.py (Demo.show): Flush stdout after each block, so
 	computationally intensive blocks don't appear to stall the demo.
 
 2006-01-24  Ville Vainio  <[e-mail]>
 
 	* iplib.py, hooks.py: 'result_display' hook can return a non-None
 	value to manipulate resulting history entry.
 	
 	* ipapi.py: Moved TryNext here from hooks.py. Moved functions
 	to instance methods of IPApi class, to make extending an embedded
 	IPython feasible. See ext_rehashdir.py for example usage.
 	
 	* Merged 1071-1076 from branches/0.7.1
 
 
 2006-01-23  Fernando Perez  <[e-mail]>
 
 	* tools/release (daystamp): Fix build tools to use the new
 	eggsetup.py script to build lightweight eggs.
 
 	* Applied changesets 1062 and 1064 before 0.7.1 release.
 	
 	* IPython/Magic.py (magic_history): Add '-r' option to %hist, to
 	see the raw input history (without conversions like %ls ->
 	ipmagic("ls")).  After a request from W. Stein, SAGE
 	(http://modular.ucsd.edu/sage) developer.  This information is
 	stored in the input_hist_raw attribute of the IPython instance, so
 	developers can access it if needed (it's an InputList instance).
 	
 	* Versionstring = 0.7.2.svn
 	
 	* eggsetup.py: A separate script for constructing eggs, creates
 	proper launch scripts even on Windows (an .exe file in
 	\python24\scripts).
 	
 	* ipapi.py: launch_new_instance, launch entry point needed for the
 	egg.
 
 2006-01-23  Ville Vainio  <[e-mail]>
 
 	* Added %cpaste magic for pasting python code
 
 2006-01-22  Ville Vainio  <[e-mail]>
 
 	* Merge from branches/0.7.1 into trunk, revs 1052-1057
 	
 	* Versionstring = 0.7.2.svn
 	
 	* eggsetup.py: A separate script for constructing eggs, creates
 	proper launch scripts even on Windows (an .exe file in
 	\python24\scripts).
 	
 	* ipapi.py: launch_new_instance, launch entry point needed for the
 	egg.
 
 2006-01-22  Fernando Perez  <[e-mail]>
 
 	* IPython/OInspect.py (Inspector.pinfo): fix bug where foo?? or
 	%pfile foo would print the file for foo even if it was a binary.
 	Now, extensions '.so' and '.dll' are skipped.
 
 	* IPython/Shell.py (MTInteractiveShell.__init__): Fix threading
 	bug, where macros would fail in all threaded modes.  I'm not 100%
 	sure, so I'm going to put out an rc instead of making a release
 	today, and wait for feedback for at least a few days.
 
 	* IPython/iplib.py (handle_normal): fix (finally? somehow I doubt
 	it...) the handling of pasting external code with autoindent on.
 	To get out of a multiline input, the rule will appear for most
 	users unchanged: two blank lines or change the indent level
 	proposed by IPython.  But there is a twist now: you can
 	add/subtract only *one or two spaces*.  If you add/subtract three
 	or more (unless you completely delete the line), IPython will
 	accept that line, and you'll need to enter a second one of pure
 	whitespace.  I know it sounds complicated, but I can't find a
 	different solution that covers all the cases, with the right
 	heuristics.  Hopefully in actual use, nobody will really notice
 	all these strange rules and things will 'just work'.
 
 2006-01-21  Fernando Perez  <[e-mail]>
 
 	* IPython/iplib.py (interact): catch exceptions which can be
 	triggered asynchronously by signal handlers.  Thanks to an
 	automatic crash report, submitted by Colin Kingsley
 	<tercel-AT-gentoo.org>.
 	
 2006-01-20  Ville Vainio  <[e-mail]>
 
 	* Ipython/Extensions/ext_rehashdir.py: Created a usable example
 	(%rehashdir, very useful, try it out) of how to extend ipython
 	with new magics. Also added Extensions dir to pythonpath to make
 	importing extensions easy.
 	
 	* %store now complains when trying to store interactively declared
 	classes / instances of those classes.
 	
 	* Extensions/ipy_system_conf.py, UserConfig/ipy_user_conf.py,
 	ipmaker.py: Config rehaul. Now ipy_..._conf.py are always imported
 	if they exist, and ipy_user_conf.py with some defaults is created for
 	the user.
 	
 	* Startup rehashing done by the config file, not InterpreterExec.
 	This means system commands are available even without selecting the
 	pysh profile. It's the sensible default after all.
 
 2006-01-20  Fernando Perez  <[e-mail]>
 
 	* IPython/iplib.py (raw_input): I _think_ I got the pasting of
 	multiline code with autoindent on working.  But I am really not
 	sure, so this needs more testing.  Will commit a debug-enabled
 	version for now, while I test it some more, so that Ville and
 	others may also catch any problems.  Also made
 	self.indent_current_str() a method, to ensure that there's no
 	chance of the indent space count and the corresponding string
 	falling out of sync.  All code needing the string should just call
 	the method.
 
 2006-01-18  Fernando Perez  <[e-mail]>
 
 	* IPython/Magic.py (magic_edit): fix check for when users don't
 	save their output files, the try/except was in the wrong section.
 
 2006-01-17  Fernando Perez  <[e-mail]>
 
 	* IPython/Magic.py (magic_run): fix __file__ global missing from
 	script's namespace when executed via %run.  After a report by
 	Vivian.
 
 	* IPython/Debugger.py (Pdb.__init__): Fix breakage with '%run -d'
 	when using python 2.4.  The parent constructor changed in 2.4, and
 	we need to track it directly (we can't call it, as it messes up
 	readline and tab-completion inside our pdb would stop working).
 	After a bug report by R. Bernstein <rocky-AT-panix.com>.
 
 2006-01-16  Ville Vainio  <[e-mail]>
 
 	* Ipython/magic.py: Reverted back to old %edit functionality
 	that returns file contents on exit.
 	
 	* IPython/path.py: Added Jason Orendorff's "path" module to
 	IPython tree, http://www.jorendorff.com/articles/python/path/.
 	You can get path objects conveniently through %sc, and !!, e.g.:
 	 sc files=ls
 	 for p in files.paths: # or files.p
 	     print p,p.mtime
 	
 	* Ipython/iplib.py:"," and ";" autoquoting-upon-autocall
 	now work again without considering the exclusion regexp -
 	hence, things like ',foo my/path' turn to 'foo("my/path")'
 	instead of syntax error.
 	
 
 2006-01-14  Ville Vainio  <[e-mail]>
 
 	* IPython/ipapi.py (ashook, asmagic, options): Added convenience
 	ipapi decorators for python 2.4 users, options() provides access to rc
 	data.
 	
 	* IPython/Magic.py (magic_cd): %cd now accepts backslashes
 	as path separators (even on Linux ;-). Space character after
 	backslash (as yielded by tab completer) is still space;
 	"%cd long\ name" works as expected.
 
 	* IPython/ipapi.py,hooks.py,iplib.py: Hooks now implemented
 	as "chain of command", with priority. API stays the same,
 	TryNext exception raised by a hook function signals that
 	current hook failed and next hook should try handling it, as
 	suggested by Walter Dörwald <[e-mail]>. Walter also
 	requested configurable display hook, which is now implemented.
 
 2006-01-13  Ville Vainio  <[e-mail]>
 
 	* IPython/platutils*.py: platform specific utility functions,
 	so far only set_term_title is implemented (change terminal
 	label in windowing systems). %cd now changes the title to
 	current dir.
 
 	* IPython/Release.py: Added myself to "authors" list,
 	had to create new files.
 	
 	* IPython/iplib.py (handle_shell_escape): fixed logical flaw in
 	shell escape; not a known bug but had potential to be one in the
 	future.
 
 	* IPython/ipapi.py (added),OInspect.py,iplib.py: "Public"
 	extension API for IPython! See the module for usage example. Fix
 	OInspect for docstring-less magic functions.
 	
 
 2006-01-13  Fernando Perez  <[e-mail]>
 
 	* IPython/iplib.py (raw_input): temporarily deactivate all
 	attempts at allowing pasting of code with autoindent on.  It
 	introduced bugs (reported by Prabhu) and I can't seem to find a
 	robust combination which works in all cases.  Will have to revisit
 	later.
 
 	* IPython/genutils.py: remove isspace() function.  We've dropped
 	2.2 compatibility, so it's OK to use the string method.
 
 2006-01-12  Fernando Perez  <[e-mail]>
 
 	* IPython/iplib.py (InteractiveShell.__init__): fix regexp
 	matching what NOT to autocall on, to include all python binary
 	operators (including things like 'and', 'or', 'is' and 'in').
 	Prompted by a bug report on 'foo & bar', but I realized we had
 	many more potential bug cases with other operators.  The regexp is
 	self.re_exclude_auto, it's fairly commented.
 
 2006-01-12  Ville Vainio  <[e-mail]>
 
 	* IPython/iplib.py (make_quoted_expr,handle_shell_escape):
 	Prettified and hardened string/backslash quoting with ipsystem(),
 	ipalias() and ipmagic(). Now even \ characters are passed to
 	%magics, !shell escapes and aliases exactly as they are in the
 	ipython command line. Should improve backslash experience,
 	particularly in Windows (path delimiter for some commands that
 	won't understand '/'), but Unix benefits as well (regexps). %cd
 	magic still doesn't support backslash path delimiters, though. Also
 	deleted all pretense of supporting multiline command strings in
 	!system or %magic commands. Thanks to Jerry McRae for suggestions.
 	
 	* doc/build_doc_instructions.txt added. Documentation on how to
 	use doc/update_manual.py, added yesterday. Both files contributed
 	by Jörgen Stenarson <jorgen.stenarson-AT-bostream.nu>. This slates
 	doc/*.sh for deprecation at a later date.
 	
 	* /ipython.py Added ipython.py to root directory for
 	zero-installation (tar xzvf ipython.tgz; cd ipython; python
 	ipython.py) and development convenience (no need to keep doing
 	"setup.py install" between changes).
 	
 	* Made ! and !! shell escapes work (again) in multiline expressions:
 	  if 1:
 	      !ls
 	      !!ls
 
 2006-01-12  Fernando Perez  <[e-mail]>
 
 	* IPython/ipstruct.py (Struct): Rename IPython.Struct to
 	IPython.ipstruct, to avoid local shadowing of the stdlib 'struct'
 	module in case-insensitive installation.  Was causing crashes
 	under win32.  Closes http://www.scipy.net/roundup/ipython/issue49.
 
 	* IPython/Magic.py (magic_pycat): Fix pycat, patch by Marien Zwart
 	<marienz-AT-gentoo.org>, closes
 	http://www.scipy.net/roundup/ipython/issue51.
 
 2006-01-11  Fernando Perez  <[e-mail]>
 
 	* IPython/Shell.py (IPShellGTK.on_timer): Finally fix the
 	problem of excessive CPU usage under *nix and keyboard lag under
 	win32.
 
 2006-01-10  *** Released version 0.7.0
 
 2006-01-10  Fernando Perez  <[e-mail]>
 
 	* IPython/Release.py (revision): tag version number to 0.7.0,
 	ready for release.
 
 	* IPython/Magic.py (magic_edit): Add print statement to %edit so
 	it informs the user of the name of the temp. file used.  This can
 	help if you decide later to reuse that same file, so you know
 	where to copy the info from.
 
 2006-01-09  Fernando Perez  <[e-mail]>
 
 	* setup_bdist_egg.py: little script to build an egg.  Added
 	support in the release tools as well.
 
 2006-01-08  Fernando Perez  <[e-mail]>
 
 	* IPython/Shell.py (IPShellWX.__init__): add support for WXPython
 	version selection (new -wxversion command line and ipythonrc
 	parameter).  Patch contributed by Arnd Baecker
 	<arnd.baecker-AT-web.de>.
 
 	* IPython/iplib.py (embed_mainloop): fix tab-completion in
 	embedded instances, for variables defined at the interactive
 	prompt of the embedded ipython.  Reported by Arnd.
 
 	* IPython/Magic.py (magic_autocall): Fix %autocall magic.  Now
 	it can be used as a (stateful) toggle, or with a direct parameter.
 
 	* IPython/ultraTB.py (_fixed_getinnerframes): remove debug assert which
 	could be triggered in certain cases and cause the traceback
 	printer not to work.
 
 2006-01-07  Fernando Perez  <[e-mail]>
 
 	* IPython/iplib.py (_should_recompile): Small fix, closes
 	http://www.scipy.net/roundup/ipython/issue48.  Patch by Scott.
 
 2006-01-04  Fernando Perez  <[e-mail]>
 
 	* IPython/Shell.py (IPShellGTK.mainloop): fix bug in the GTK
 	backend for matplotlib (100% cpu utiliziation).  Thanks to Charlie
 	Moad for help with tracking it down.
 
 	* IPython/iplib.py (handle_auto): fix autocall handling for
 	objects which support BOTH __getitem__ and __call__ (so that f [x]
 	is left alone, instead of becoming f([x]) automatically).
 
 	* IPython/Magic.py (magic_cd): fix crash when cd -b was used.
 	Ville's patch.
 
 2006-01-03  Fernando Perez  <[e-mail]>
 
 	* IPython/iplib.py (handle_auto): changed autocall semantics to
 	include 'smart' mode, where the autocall transformation is NOT
 	applied if there are no arguments on the line.  This allows you to
 	just type 'foo' if foo is a callable to see its internal form,
 	instead of having it called with no arguments (typically a
 	mistake).  The old 'full' autocall still exists: for that, you
 	need to set the 'autocall' parameter to 2 in your ipythonrc file.
 
 	* IPython/completer.py (Completer.attr_matches): add
 	tab-completion support for Enthoughts' traits.  After a report by
 	Arnd and a patch by Prabhu.
 
 2006-01-02  Fernando Perez  <[e-mail]>
 
 	* IPython/ultraTB.py (_fixed_getinnerframes): added Alex
 	Schmolck's patch to fix inspect.getinnerframes().
 
 	* IPython/iplib.py (InteractiveShell.__init__): significant fixes
 	for embedded instances, regarding handling of namespaces and items
 	added to the __builtin__ one.  Multiple embedded instances and
 	recursive embeddings should work better now (though I'm not sure
 	I've got all the corner cases fixed, that code is a bit of a brain
 	twister).
 
 	* IPython/Magic.py (magic_edit): added support to edit in-memory
 	macros (automatically creates the necessary temp files).  %edit
 	also doesn't return the file contents anymore, it's just noise.
 
 	* IPython/completer.py (Completer.attr_matches): revert change to
 	complete only on attributes listed in __all__.  I realized it
 	cripples the tab-completion system as a tool for exploring the
 	internals of unknown libraries (it renders any non-__all__
 	attribute off-limits).  I got bit by this when trying to see
 	something inside the dis module.
 
 2005-12-31  Fernando Perez  <[e-mail]>
 
 	* IPython/iplib.py (InteractiveShell.__init__): add .meta
 	namespace for users and extension writers to hold data in.  This
 	follows the discussion in
 	http://projects.scipy.org/ipython/ipython/wiki/RefactoringIPython.
 
 	* IPython/completer.py (IPCompleter.complete): small patch to help
 	tab-completion under Emacs, after a suggestion by John Barnard
 	<barnarj-AT-ccf.org>.
 
 	* IPython/Magic.py (Magic.extract_input_slices): added support for
 	the slice notation in magics to use N-M to represent numbers N...M
 	(closed endpoints).  This is used by %macro and %save.
 
 	* IPython/completer.py (Completer.attr_matches): for modules which
 	define __all__, complete only on those.  After a patch by Jeffrey
 	Collins <jcollins_boulder-AT-earthlink.net>.  Also, clean up and
 	speed up this routine.
 
 	* IPython/Logger.py (Logger.log): fix a history handling bug.  I
 	don't know if this is the end of it, but the behavior now is
 	certainly much more correct.  Note that coupled with macros,
 	slightly surprising (at first) behavior may occur: a macro will in
 	general expand to multiple lines of input, so upon exiting, the
 	in/out counters will both be bumped by the corresponding amount
 	(as if the macro's contents had been typed interactively).  Typing
 	%hist will reveal the intermediate (silently processed) lines.
 
 	* IPython/Magic.py (magic_run): fix a subtle bug which could cause
 	pickle to fail (%run was overwriting __main__ and not restoring
 	it, but pickle relies on __main__ to operate).
 
 	* IPython/iplib.py (InteractiveShell): fix pdb calling: I'm now
 	using properties, but forgot to make the main InteractiveShell
 	class a new-style class.  Properties fail silently, and
 	mysteriously, with old-style class (getters work, but
 	setters don't do anything).
 
 2005-12-30  Fernando Perez  <[e-mail]>
 
 	* IPython/Magic.py (magic_history): fix history reporting bug (I
 	know some nasties are still there, I just can't seem to find a
 	reproducible test case to track them down; the input history is
 	falling out of sync...)
 
 	* IPython/iplib.py (handle_shell_escape): fix bug where both
 	aliases and system accesses where broken for indented code (such
 	as loops).
 
 	* IPython/genutils.py (shell): fix small but critical bug for
 	win32 system access.
 
 2005-12-29  Fernando Perez  <[e-mail]>
 
 	* IPython/iplib.py (showtraceback): remove use of the
 	sys.last_{type/value/traceback} structures, which are non
 	thread-safe.
 	(_prefilter): change control flow to ensure that we NEVER
 	introspect objects when autocall is off.  This will guarantee that
 	having an input line of the form 'x.y', where access to attribute
 	'y' has side effects, doesn't trigger the side effect TWICE.  It
 	is important to note that, with autocall on, these side effects
 	can still happen.
 	(ipsystem): new builtin, to complete the ip{magic/alias/system}
 	trio.  IPython offers these three kinds of special calls which are
 	not python code, and it's a good thing to have their call method
 	be accessible as pure python functions (not just special syntax at
 	the command line).  It gives us a better internal implementation
 	structure, as well as exposing these for user scripting more
 	cleanly.
 
 	* IPython/macro.py (Macro.__init__): moved macros to a standalone
 	file.  Now that they'll be more likely to be used with the
 	persistance system (%store), I want to make sure their module path
 	doesn't change in the future, so that we don't break things for
 	users' persisted data.
 
 	* IPython/iplib.py (autoindent_update): move indentation
 	management into the _text_ processing loop, not the keyboard
 	interactive one.  This is necessary to correctly process non-typed
 	multiline input (such as macros).
 
 	* IPython/Magic.py (Magic.format_latex): patch by Stefan van der
 	Walt <stefan-AT-sun.ac.za> to fix latex formatting of docstrings,
 	which was producing problems in the resulting manual.
 	(magic_whos): improve reporting of instances (show their class,
 	instead of simply printing 'instance' which isn't terribly
 	informative).
 
 	* IPython/genutils.py (shell): commit Jorgen Stenarson's patch
 	(minor mods) to support network shares under win32.
 
 	* IPython/winconsole.py (get_console_size): add new winconsole
 	module and fixes to page_dumb() to improve its behavior under
 	win32.  Contributed by Alexander Belchenko <bialix-AT-ukr.net>.
 
 	* IPython/Magic.py (Macro): simplified Macro class to just
 	subclass list.  We've had only 2.2 compatibility for a very long
 	time, yet I was still avoiding subclassing the builtin types.  No
 	more (I'm also starting to use properties, though I won't shift to
 	2.3-specific features quite yet).
 	(magic_store): added Ville's patch for lightweight variable
 	persistence, after a request on the user list by Matt Wilkie
 	<maphew-AT-gmail.com>.  The new %store magic's docstring has full
 	details.
 
 	* IPython/iplib.py (InteractiveShell.post_config_initialization):
 	changed the default logfile name from 'ipython.log' to
 	'ipython_log.py'.  These logs are real python files, and now that
 	we have much better multiline support, people are more likely to
 	want to use them as such.  Might as well name them correctly.
 
 	* IPython/Magic.py: substantial cleanup.  While we can't stop
 	using magics as mixins, due to the existing customizations 'out
 	there' which rely on the mixin naming conventions, at least I
 	cleaned out all cross-class name usage.  So once we are OK with
 	breaking compatibility, the two systems can be separated.
 
 	* IPython/Logger.py: major cleanup.  This one is NOT a mixin
 	anymore, and the class is a fair bit less hideous as well.  New
 	features were also introduced: timestamping of input, and logging
 	of output results.  These are user-visible with the -t and -o
 	options to %logstart.  Closes
 	http://www.scipy.net/roundup/ipython/issue11 and a request by
 	William Stein (SAGE developer - http://modular.ucsd.edu/sage).
 
 2005-12-28  Fernando Perez  <[e-mail]>
 
 	* IPython/iplib.py (handle_shell_escape): add Ville's patch to
 	better handle backslashes in paths.  See the thread 'More Windows
 	questions part 2 - \/ characters revisited' on the iypthon user
 	list:
 	http://scipy.net/pipermail/ipython-user/2005-June/000907.html
 
 	(InteractiveShell.__init__): fix tab-completion bug in threaded shells.
 
 	(InteractiveShell.__init__): change threaded shells to not use the
 	ipython crash handler.  This was causing more problems than not,
 	as exceptions in the main thread (GUI code, typically) would
 	always show up as a 'crash', when they really weren't.
 
 	The colors and exception mode commands (%colors/%xmode) have been
 	synchronized to also take this into account, so users can get
 	verbose exceptions for their threaded code as well.  I also added
 	support for activating pdb inside this exception handler as well,
 	so now GUI authors can use IPython's enhanced pdb at runtime.
 
 	* IPython/ipmaker.py (make_IPython): make the autoedit_syntax flag
 	true by default, and add it to the shipped ipythonrc file.  Since
 	this asks the user before proceeding, I think it's OK to make it
 	true by default.
 
 	* IPython/Magic.py (magic_exit): make new exit/quit magics instead
 	of the previous special-casing of input in the eval loop.  I think
 	this is cleaner, as they really are commands and shouldn't have
 	a special role in the middle of the core code.
 
 2005-12-27  Fernando Perez  <[e-mail]>
 
 	* IPython/iplib.py (edit_syntax_error): added support for
 	automatically reopening the editor if the file had a syntax error
 	in it.  Thanks to scottt who provided the patch at:
 	http://www.scipy.net/roundup/ipython/issue36 (slightly modified
 	version committed).
 
 	* IPython/iplib.py (handle_normal): add suport for multi-line
 	input with emtpy lines.  This fixes
 	http://www.scipy.net/roundup/ipython/issue43 and a similar
 	discussion on the user list.
 
 	WARNING: a behavior change is necessarily introduced to support
 	blank lines: now a single blank line with whitespace does NOT
 	break the input loop, which means that when autoindent is on, by
 	default hitting return on the next (indented) line does NOT exit.
 
 	Instead, to exit a multiline input you can either have:
 
 	  - TWO whitespace lines (just hit return again), or
 	  - a single whitespace line of a different length than provided
 	by the autoindent (add or remove a space).
 
 	* IPython/completer.py (MagicCompleter.__init__): new 'completer'
 	module to better organize all readline-related functionality.
 	I've deleted FlexCompleter and put all completion clases here.
 
 	* IPython/iplib.py (raw_input): improve indentation management.
 	It is now possible to paste indented code with autoindent on, and
 	the code is interpreted correctly (though it still looks bad on
 	screen, due to the line-oriented nature of ipython).
 	(MagicCompleter.complete): change behavior so that a TAB key on an
 	otherwise empty line actually inserts a tab, instead of completing
 	on the entire global namespace.  This makes it easier to use the
 	TAB key for indentation.  After a request by Hans Meine
 	<hans_meine-AT-gmx.net>
 	(_prefilter): add support so that typing plain 'exit' or 'quit'
 	does a sensible thing.  Originally I tried to deviate as little as
 	possible from the default python behavior, but even that one may
 	change in this direction (thread on python-dev to that effect).
 	Regardless, ipython should do the right thing even if CPython's
 	'>>>' prompt doesn't.
 	(InteractiveShell): removed subclassing code.InteractiveConsole
 	class.  By now we'd overridden just about all of its methods: I've
 	copied the remaining two over, and now ipython is a standalone
 	class.  This will provide a clearer picture for the chainsaw
 	branch refactoring.
 
 2005-12-26  Fernando Perez  <[e-mail]>
 
 	* IPython/ultraTB.py (VerboseTB.text): harden reporting against
 	failures for objects which break when dir() is called on them.
 
 	* IPython/FlexCompleter.py (Completer.__init__): Added support for
 	distinct local and global namespaces in the completer API.  This
 	change allows us to properly handle completion with distinct
 	scopes, including in embedded instances (this had never really
 	worked correctly).
 
 	Note: this introduces a change in the constructor for
 	MagicCompleter, as a new global_namespace parameter is now the
 	second argument (the others were bumped one position).
 
 2005-12-25  Fernando Perez  <[e-mail]>
 
 	* IPython/iplib.py (embed_mainloop): fix tab-completion in
 	embedded instances (which can be done now thanks to Vivian's
 	frame-handling fixes for pdb).
 	(InteractiveShell.__init__): Fix namespace handling problem in
 	embedded instances.  We were overwriting __main__ unconditionally,
 	and this should only be done for 'full' (non-embedded) IPython;
 	embedded instances must respect the caller's __main__.  Thanks to
 	a bug report by Yaroslav Bulatov <yaroslavvb-AT-gmail.com>
 
 2005-12-24  Fernando Perez  <[e-mail]>
 
 	* setup.py: added download_url to setup().  This registers the
 	download address at PyPI, which is not only useful to humans
 	browsing the site, but is also picked up by setuptools (the Eggs
 	machinery).  Thanks to Ville and R. Kern for the info/discussion
 	on this.
 
 2005-12-23  Fernando Perez  <[e-mail]>
 
 	* IPython/Debugger.py (Pdb.__init__): Major pdb mode enhancements.
 	This brings a lot of nice functionality to the pdb mode, which now
 	has tab-completion, syntax highlighting, and better stack handling
 	than before.  Many thanks to Vivian De Smedt
 	<vivian-AT-vdesmedt.com> for the original patches.
 
 2005-12-08  Fernando Perez  <[e-mail]>
 
 	* IPython/Shell.py (IPShellGTK.mainloop): fix mainloop() calling
 	sequence to consistently accept the banner argument.  The
 	inconsistency was tripping SAGE, thanks to Gary Zablackis
 	<gzabl-AT-yahoo.com> for the report.
 
 2005-11-15  Fernando Perez  <[e-mail]>
 
 	* IPython/iplib.py (InteractiveShell.post_config_initialization):
 	Fix bug where a naked 'alias' call in the ipythonrc file would
 	cause a crash.  Bug reported by Jorgen Stenarson.
 
 2005-11-15  Fernando Perez  <[e-mail]>
 
 	* IPython/ipmaker.py (make_IPython): cleanups which should improve
 	startup time.
 
 	* IPython/iplib.py (runcode): my globals 'fix' for embedded
 	instances had introduced a bug with globals in normal code.  Now
 	it's working in all cases.
 
 	* IPython/Magic.py (magic_psearch): Finish wildcard cleanup and
 	API changes.  A new ipytonrc option, 'wildcards_case_sensitive'
 	has been introduced to set the default case sensitivity of the
 	searches.  Users can still select either mode at runtime on a
 	per-search basis.
 
 2005-11-13 Fernando Perez   <[e-mail]>
 
 	* IPython/wildcard.py (NameSpace.__init__): fix resolution of
 	attributes in wildcard searches for subclasses.  Modified version
 	of a patch by Jorgen.
 
 2005-11-12 Fernando Perez   <[e-mail]>
 
 	* IPython/iplib.py (embed_mainloop): Fix handling of globals for
 	embedded instances.  I added a user_global_ns attribute to the
 	InteractiveShell class to handle this.
 
 2005-10-31  Fernando Perez  <[e-mail]>
 
 	* IPython/Shell.py (IPShellGTK.mainloop): Change timeout_add to
 	idle_add, which fixes horrible keyboard lag problems under gtk 2.6
 	(reported under win32, but may happen also in other platforms).
 	Bug report and fix courtesy of Sean Moore <smm-AT-logic.bm>
 
 2005-10-15  Fernando Perez  <[e-mail]>
 
 	* IPython/Magic.py (magic_psearch): new support for wildcard
 	patterns.  Now, typing ?a*b will list all names which begin with a
 	and end in b, for example.  The %psearch magic has full
 	docstrings.  Many thanks to Jörgen Stenarson
 	<jorgen.stenarson-AT-bostream.nu>, author of the patches
 	implementing this functionality.
 
 2005-09-27  Fernando Perez  <[e-mail]>
 
 	* Manual: fixed long-standing annoyance of double-dashes (as in
 	--prefix=~, for example) being stripped in the HTML version.  This
 	is a latex2html bug, but a workaround was provided.  Many thanks
 	to George K. Thiruvathukal <gthiruv-AT-luc.edu> for the detailed
 	help, and Michael Tobis <mtobis-AT-gmail.com> for getting the ball
 	rolling.  This seemingly small issue had tripped a number of users
 	when first installing, so I'm glad to see it gone.
 	
 2005-09-27  Fernando Perez  <[e-mail]>
 
 	* IPython/Extensions/numeric_formats.py: fix missing import,
 	reported by Stephen Walton.
 
 2005-09-24  Fernando Perez  <[e-mail]>
 
 	* IPython/demo.py: finish demo module, fully documented now.
 
 	* IPython/genutils.py (file_read): simple little utility to read a
 	file and ensure it's closed afterwards.
 
 2005-09-23  Fernando Perez  <[e-mail]>
 
 	* IPython/demo.py (Demo.__init__): added support for individually
 	tagging blocks for automatic execution.
 
 	* IPython/Magic.py (magic_pycat): new %pycat magic for showing
 	syntax-highlighted python sources, requested by John.
 
 2005-09-22  Fernando Perez  <[e-mail]>
 
 	* IPython/demo.py (Demo.again): fix bug where again() blocks after
 	finishing.
 
 	* IPython/genutils.py (shlex_split): moved from Magic to here,
 	where all 2.2 compatibility stuff lives.  I needed it for demo.py.
 
 	* IPython/demo.py (Demo.__init__): added support for silent
 	blocks, improved marks as regexps, docstrings written.
 	(Demo.__init__): better docstring, added support for sys.argv.
 
 	* IPython/genutils.py (marquee): little utility used by the demo
 	code, handy in general.
 
 	* IPython/demo.py (Demo.__init__): new class for interactive
 	demos.  Not documented yet, I just wrote it in a hurry for
 	scipy'05.  Will docstring later.
 
 2005-09-20  Fernando Perez  <[e-mail]>
 
 	* IPython/Shell.py (sigint_handler): Drastic simplification which
 	also seems to make Ctrl-C work correctly across threads!  This is
 	so simple, that I can't beleive I'd missed it before.  Needs more
 	testing, though.
 	(KBINT): Never mind, revert changes.  I'm sure I'd tried something
 	like this before...
 
 	* IPython/genutils.py (get_home_dir): add protection against
 	non-dirs in win32 registry.
 
 	* IPython/iplib.py (InteractiveShell.alias_table_validate): fix
 	bug where dict was mutated while iterating (pysh crash).
 
 2005-09-06  Fernando Perez  <[e-mail]>
 
 	* IPython/iplib.py (handle_auto): Fix inconsistency arising from
 	spurious newlines added by this routine.  After a report by
 	F. Mantegazza.
 
 2005-09-05  Fernando Perez  <[e-mail]>
 
 	* IPython/Shell.py (hijack_gtk): remove pygtk.require("2.0")
 	calls.  These were a leftover from the GTK 1.x days, and can cause
 	problems in certain cases (after a report by John Hunter).
 
 	* IPython/iplib.py (InteractiveShell.__init__): Trap exception if
 	os.getcwd() fails at init time.  Thanks to patch from David Remahl
 	<chmod007-AT-mac.com>.
 	(InteractiveShell.__init__): prevent certain special magics from
 	being shadowed by aliases.  Closes
 	http://www.scipy.net/roundup/ipython/issue41.
 
 2005-08-31  Fernando Perez  <[e-mail]>
 
 	* IPython/iplib.py (InteractiveShell.complete): Added new
 	top-level completion method to expose the completion mechanism
 	beyond readline-based environments.
 
 2005-08-19  Fernando Perez  <[e-mail]>
 
 	* tools/ipsvnc (svnversion): fix svnversion capture.
 
 	* IPython/iplib.py (InteractiveShell.__init__): Add has_readline
 	attribute to self, which was missing.  Before, it was set by a
 	routine which in certain cases wasn't being called, so the
 	instance could end up missing the attribute.  This caused a crash.
 	Closes http://www.scipy.net/roundup/ipython/issue40.
 
 2005-08-16  Fernando Perez  <[e-mail]>
 
 	* IPython/ultraTB.py (VerboseTB.text): don't crash if object
 	contains non-string attribute.  Closes
 	http://www.scipy.net/roundup/ipython/issue38.
 
 2005-08-14  Fernando Perez  <[e-mail]>
 
 	* tools/ipsvnc: Minor improvements, to add changeset info.
 
 2005-08-12  Fernando Perez  <[e-mail]>
 
 	* IPython/iplib.py (runsource): remove self.code_to_run_src
 	attribute.  I realized this is nothing more than
 	'\n'.join(self.buffer), and having the same data in two different
 	places is just asking for synchronization bugs.  This may impact
 	people who have custom exception handlers, so I need to warn

 	* IPython/genutils.py: fix 2.2 compatibility (generators)
 
 2005-07-18  Fernando Perez  <[e-mail]>
 
 	* IPython/genutils.py (get_home_dir): fix to help users with
 	invalid $HOME under win32.
 
 2005-07-17  Fernando Perez  <[e-mail]>
 
 	* IPython/Prompts.py (str_safe): Make unicode-safe.  Also remove
 	some old hacks and clean up a bit other routines; code should be
 	simpler and a bit faster.
 
 	* IPython/iplib.py (interact): removed some last-resort attempts
 	to survive broken stdout/stderr.  That code was only making it
 	harder to abstract out the i/o (necessary for gui integration),
 	and the crashes it could prevent were extremely rare in practice
 	(besides being fully user-induced in a pretty violent manner).
 
 	* IPython/genutils.py (IOStream.__init__): Simplify the i/o stuff.
 	Nothing major yet, but the code is simpler to read; this should
 	make it easier to do more serious modifications in the future.
 
 	* IPython/Extensions/InterpreterExec.py: Fix auto-quoting in pysh,
 	which broke in .15 (thanks to a report by Ville).
 
 	* IPython/Itpl.py (Itpl.__init__): add unicode support (it may not
 	be quite correct, I know next to nothing about unicode).  This
 	will allow unicode strings to be used in prompts, amongst other
 	cases.  It also will prevent ipython from crashing when unicode
 	shows up unexpectedly in many places.  If ascii encoding fails, we
 	assume utf_8.  Currently the encoding is not a user-visible
 	setting, though it could be made so if there is demand for it.
 
 	* IPython/ipmaker.py (make_IPython): remove old 2.1-specific hack.
 
 	* IPython/Struct.py (Struct.merge): switch keys() to iterator.
 
 	* IPython/background_jobs.py: moved 2.2 compatibility to genutils.
 
 	* IPython/genutils.py: Add 2.2 compatibility here, so all other
 	code can work transparently for 2.2/2.3.
 
 2005-07-16  Fernando Perez  <[e-mail]>
 
 	* IPython/ultraTB.py (ExceptionColors): Make a global variable
 	out of the color scheme table used for coloring exception
 	tracebacks.  This allows user code to add new schemes at runtime.
 	This is a minimally modified version of the patch at
 	http://www.scipy.net/roundup/ipython/issue35, many thanks to pabw
 	for the contribution.
 
 	* IPython/FlexCompleter.py (Completer.attr_matches): Add a
 	slightly modified version of the patch in
 	http://www.scipy.net/roundup/ipython/issue34, which also allows me
 	to remove the previous try/except solution (which was costlier).
 	Thanks to Gaetan Lehmann <gaetan.lehmann-AT-jouy.inra.fr> for the fix.
 
 2005-06-08  Fernando Perez  <[e-mail]>
 
 	* IPython/iplib.py (write/write_err): Add methods to abstract all
 	I/O a bit more.
 
 	* IPython/Shell.py (IPShellGTK.mainloop): Fix GTK deprecation
 	warning, reported by Aric Hagberg, fix by JD Hunter.
 
 2005-06-02  *** Released version 0.6.15
 
 2005-06-01  Fernando Perez  <[e-mail]>
 
 	* IPython/iplib.py (MagicCompleter.file_matches): Fix
 	tab-completion of filenames within open-quoted strings.  Note that
 	this requires that in ~/.ipython/ipythonrc, users change the
 	readline delimiters configuration to read:
 
 	readline_remove_delims -/~
 	
 
 2005-05-31  *** Released version 0.6.14
 
 2005-05-29  Fernando Perez  <[e-mail]>
 
 	* IPython/ultraTB.py (VerboseTB.text): Fix crash for tracebacks
 	with files not on the filesystem.  Reported by Eliyahu Sandler
 	<[e-mail]>
 
 2005-05-22  Fernando Perez  <[e-mail]>
 
 	* IPython/iplib.py: Fix a few crashes in the --upgrade option.
 	After an initial report by LUK ShunTim <[e-mail]>.
 
 2005-05-19  Fernando Perez  <[e-mail]>
 
 	* IPython/iplib.py (safe_execfile): close a file which could be
 	left open (causing problems in win32, which locks open files).
 	Thanks to a bug report by D Brown <[e-mail]>.
 
 2005-05-18  Fernando Perez  <[e-mail]>
 
 	* IPython/Shell.py (MatplotlibShellBase.mplot_exec): pass all
 	keyword arguments correctly to safe_execfile().
 
 2005-05-13  Fernando Perez  <[e-mail]>
 
 	* ipython.1: Added info about Qt to manpage, and threads warning
 	to usage page (invoked with --help).
 
 	* IPython/iplib.py (MagicCompleter.python_func_kw_matches): Added
 	new matcher (it goes at the end of the priority list) to do
 	tab-completion on named function arguments.  Submitted by George
 	Sakkis <gsakkis-AT-eden.rutgers.edu>.  See the thread at
 	http://www.scipy.net/pipermail/ipython-dev/2005-April/000436.html
 	for more details.
 
 	* IPython/Magic.py (magic_run): Added new -e flag to ignore
 	SystemExit exceptions in the script being run.  Thanks to a report
 	by danny shevitz <danny_shevitz-AT-yahoo.com>, about this
 	producing very annoying behavior when running unit tests.
 
 2005-05-12  Fernando Perez  <[e-mail]>
 
 	* IPython/iplib.py (handle_auto): fixed auto-quoting and parens,
 	which I'd broken (again) due to a changed regexp.  In the process,
 	added ';' as an escape to auto-quote the whole line without
 	splitting its arguments.  Thanks to a report by Jerry McRae
 	<qrs0xyc02-AT-sneakemail.com>.
 
 	* IPython/ultraTB.py (VerboseTB.text): protect against rare but
 	possible crashes caused by a TokenError.  Reported by Ed Schofield
 	<schofield-AT-ftw.at>.
 	
 2005-05-06  Fernando Perez  <[e-mail]>
 
 	* IPython/Shell.py (hijack_wx): Fix to work with WX v.2.6.
 
 2005-04-29  Fernando Perez  <[e-mail]>
 
 	* IPython/Shell.py (IPShellQt): Thanks to Denis Rivière
 	<nudz-AT-free.fr>, Yann Cointepas <yann-AT-sapetnioc.org> and Benjamin
 	Thyreau <Benji2-AT-decideur.info>, we now have a -qthread option
 	which provides support for Qt interactive usage (similar to the
 	existing one for WX and GTK).  This had been often requested.
 
 2005-04-14  *** Released version 0.6.13
 
 2005-04-08  Fernando Perez  <[e-mail]>
 
 	* IPython/Magic.py (Magic._ofind): remove docstring evaluation
 	from _ofind, which gets called on almost every input line.  Now,
 	we only try to get docstrings if they are actually going to be
 	used (the overhead of fetching unnecessary docstrings can be
 	noticeable for certain objects, such as Pyro proxies).
 
 	* IPython/iplib.py (MagicCompleter.python_matches): Change the API
 	for completers.  For some reason I had been passing them the state
 	variable, which completers never actually need, and was in
 	conflict with the rlcompleter API.  Custom completers ONLY need to
 	take the text parameter.
 
 	* IPython/Extensions/InterpreterExec.py: Fix regexp so that magics
 	work correctly in pysh.  I've also moved all the logic which used
 	to be in pysh.py here, which will prevent problems with future
 	upgrades.  However, this time I must warn users to update their
 	pysh profile to include the line
 
 	import_all IPython.Extensions.InterpreterExec
 
 	because otherwise things won't work for them.  They MUST also
 	delete pysh.py and the line
 
 	execfile pysh.py
 
 	from their ipythonrc-pysh.
 
 	* IPython/FlexCompleter.py (Completer.attr_matches): Make more
 	robust in the face of objects whose dir() returns non-strings
 	(which it shouldn't, but some broken libs like ITK do).  Thanks to
 	a patch by John Hunter (implemented differently, though).  Also
 	minor improvements by using .extend instead of + on lists.
 
 	* pysh.py: 
 
 2005-04-06  Fernando Perez  <[e-mail]>
 
 	* IPython/ipmaker.py (make_IPython): Make multi_line_specials on
 	by default, so that all users benefit from it.  Those who don't
 	want it can still turn it off.
 
 	* IPython/UserConfig/ipythonrc: Add multi_line_specials to the
 	config file, I'd forgotten about this, so users were getting it
 	off by default.
 
 	* IPython/iplib.py (ipmagic): big overhaul of the magic system for
 	consistency.  Now magics can be called in multiline statements,
 	and python variables can be expanded in magic calls via $var.
 	This makes the magic system behave just like aliases or !system
 	calls.
 
 2005-03-28  Fernando Perez  <[e-mail]>
 
 	* IPython/iplib.py (handle_auto): cleanup to use %s instead of
 	expensive string additions for building command.  Add support for
 	trailing ';' when autocall is used.
 
 2005-03-26  Fernando Perez  <[e-mail]>
 
 	* ipython.el: Fix http://www.scipy.net/roundup/ipython/issue31.
 	Bugfix by A. Schmolck, the ipython.el maintainer.  Also make
 	ipython.el robust against prompts with any number of spaces
 	(including 0) after the ':' character.
 
 	* IPython/Prompts.py (Prompt2.set_p_str): Fix spurious space in
 	continuation prompt, which misled users to think the line was
 	already indented.  Closes debian Bug#300847, reported to me by
 	Norbert Tretkowski <tretkowski-AT-inittab.de>.
 
 2005-03-23  Fernando Perez  <[e-mail]>
 
 	* IPython/Prompts.py (Prompt1.__str__): Make sure that prompts are
 	properly aligned if they have embedded newlines.
 
 	* IPython/iplib.py (runlines): Add a public method to expose
 	IPython's code execution machinery, so that users can run strings
 	as if they had been typed at the prompt interactively.
 	(InteractiveShell.__init__): Added getoutput() to the __IPYTHON__
 	methods which can call the system shell, but with python variable
 	expansion.  The three such methods are: __IPYTHON__.system,
 	.getoutput and .getoutputerror.  These need to be documented in a
 	'public API' section (to be written) of the manual.
 
 2005-03-20  Fernando Perez  <[e-mail]>
 
 	* IPython/iplib.py (InteractiveShell.set_custom_exc): new system
 	for custom exception handling.  This is quite powerful, and it
 	allows for user-installable exception handlers which can trap
 	custom exceptions at runtime and treat them separately from
 	IPython's default mechanisms.  At the request of Frédéric
 	Mantegazza <mantegazza-AT-ill.fr>.
 	(InteractiveShell.set_custom_completer): public API function to
 	add new completers at runtime.
 
 2005-03-19  Fernando Perez  <[e-mail]>
 
 	* IPython/OInspect.py (getdoc): Add a call to obj.getdoc(), to
 	allow objects which provide their docstrings via non-standard
 	mechanisms (like Pyro proxies) to still be inspected by ipython's
 	? system.
 
 	* IPython/iplib.py (InteractiveShell.__init__): back off the _o/_e
 	automatic capture system.  I tried quite hard to make it work
 	reliably, and simply failed.  I tried many combinations with the
 	subprocess module, but eventually nothing worked in all needed
 	cases (not blocking stdin for the child, duplicating stdout
 	without blocking, etc).  The new %sc/%sx still do capture to these
 	magical list/string objects which make shell use much more
 	conveninent, so not all is lost.
 
 	XXX - FIX MANUAL for the change above!
 
 	(runsource): I copied code.py's runsource() into ipython to modify
 	it a bit.  Now the code object and source to be executed are
 	stored in ipython.  This makes this info accessible to third-party
 	tools, like custom exception handlers.  After a request by Frédéric
 	Mantegazza <mantegazza-AT-ill.fr>.
 
 	* IPython/UserConfig/ipythonrc: Add up/down arrow keys to
 	history-search via readline (like C-p/C-n).  I'd wanted this for a
 	long time, but only recently found out how to do it.  For users
 	who already have their ipythonrc files made and want this, just
 	add:
 
 	readline_parse_and_bind "\e[A": history-search-backward
 	readline_parse_and_bind "\e[B": history-search-forward
 
 2005-03-18  Fernando Perez  <[e-mail]>
 
 	* IPython/Magic.py (magic_sc): %sc and %sx now use the fancy
 	LSString and SList classes which allow transparent conversions
 	between list mode and whitespace-separated string.
 	(magic_r): Fix recursion problem in %r.
 
 	* IPython/genutils.py (LSString): New class to be used for
 	automatic storage of the results of all alias/system calls in _o
 	and _e (stdout/err).  These provide a .l/.list attribute which
 	does automatic splitting on newlines.  This means that for most
 	uses, you'll never need to do capturing of output with %sc/%sx
 	anymore, since ipython keeps this always done for you.  Note that
 	only the LAST results are stored, the _o/e variables are
 	overwritten on each call.  If you need to save their contents
 	further, simply bind them to any other name.
 
 2005-03-17  Fernando Perez  <[e-mail]>
 
 	* IPython/Prompts.py (BasePrompt.cwd_filt): a few more fixes for
 	prompt namespace handling.
 
 2005-03-16  Fernando Perez  <[e-mail]>
 
 	* IPython/Prompts.py (CachedOutput.__init__): Fix default and
 	classic prompts to be '>>> ' (final space was missing, and it
 	trips the emacs python mode).
 	(BasePrompt.__str__): Added safe support for dynamic prompt
 	strings.  Now you can set your prompt string to be '$x', and the
 	value of x will be printed from your interactive namespace.  The
 	interpolation syntax includes the full Itpl support, so
 	${foo()+x+bar()} is a valid prompt string now, and the function
 	calls will be made at runtime.
 
 2005-03-15  Fernando Perez  <[e-mail]>
 
 	* IPython/Magic.py (magic_history): renamed %hist to %history, to
 	avoid name clashes in pylab.  %hist still works, it just forwards
 	the call to %history.
 
 2005-03-02  *** Released version 0.6.12
 
 2005-03-02  Fernando Perez  <[e-mail]>
 
 	* IPython/iplib.py (handle_magic): log magic calls properly as
 	ipmagic() function calls.
 
 	* IPython/Magic.py (magic_time): Improved %time to support
 	statements and provide wall-clock as well as CPU time.
 
 2005-02-27  Fernando Perez  <[e-mail]>
 
 	* IPython/hooks.py: New hooks module, to expose user-modifiable
 	IPython functionality in a clean manner.  For now only the editor
 	hook is actually written, and other thigns which I intend to turn
 	into proper hooks aren't yet there.  The display and prefilter
 	stuff, for example, should be hooks.  But at least now the
 	framework is in place, and the rest can be moved here with more
 	time later.  IPython had had a .hooks variable for a long time for
 	this purpose, but I'd never actually used it for anything.
 
 2005-02-26  Fernando Perez  <[e-mail]>
 
 	* IPython/ipmaker.py (make_IPython): make the default ipython
 	directory be called _ipython under win32, to follow more the
 	naming peculiarities of that platform (where buggy software like
 	Visual Sourcesafe breaks with .named directories).  Reported by
 	Ville Vainio.
 
 2005-02-23  Fernando Perez  <[e-mail]>
 
 	* IPython/iplib.py (InteractiveShell.__init__): removed a few
 	auto_aliases for win32 which were causing problems.  Users can
 	define the ones they personally like.
 
 2005-02-21  Fernando Perez  <[e-mail]>
 
 	* IPython/Magic.py (magic_time): new magic to time execution of
 	expressions.  After a request by Charles Moad <cmoad-AT-indiana.edu>.
 
 2005-02-19  Fernando Perez  <[e-mail]>
 
 	* IPython/ConfigLoader.py (ConfigLoader.load): Allow empty strings
 	into keys (for prompts, for example).
 
 	* IPython/Prompts.py (BasePrompt.set_p_str): Fix to allow empty
 	prompts in case users want them.  This introduces a small behavior
 	change: ipython does not automatically add a space to all prompts
 	anymore.  To get the old prompts with a space, users should add it
 	manually to their ipythonrc file, so for example prompt_in1 should
 	now read 'In [\#]: ' instead of 'In [\#]:'.
 	(BasePrompt.__init__): New option prompts_pad_left (only in rc
 	file) to control left-padding of secondary prompts.
 
 	* IPython/Magic.py (Magic.profile_missing_notice): Don't crash if
 	the profiler can't be imported.  Fix for Debian, which removed
 	profile.py because of License issues.  I applied a slightly
 	modified version of the original Debian patch at
 	http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=294500.
 
 2005-02-17  Fernando Perez  <[e-mail]>
 
 	* IPython/genutils.py (native_line_ends): Fix bug which would
 	cause improper line-ends under win32 b/c I was not opening files
 	in binary mode.  Bug report and fix thanks to Ville.
 
 	* IPython/iplib.py (handle_auto): Fix bug which I introduced when
 	trying to catch spurious foo[1] autocalls.  My fix actually broke
 	',/' autoquote/call with explicit escape (bad regexp).
 
 2005-02-15  *** Released version 0.6.11
 
 2005-02-14  Fernando Perez  <[e-mail]>
 
 	* IPython/background_jobs.py: New background job management
 	subsystem.  This is implemented via a new set of classes, and
 	IPython now provides a builtin 'jobs' object for background job
 	execution.  A convenience %bg magic serves as a lightweight
 	frontend for starting the more common type of calls.  This was
 	inspired by discussions with B. Granger and the BackgroundCommand
 	class described in the book Python Scripting for Computational
 	Science, by H. P. Langtangen: http://folk.uio.no/hpl/scripting
 	(although ultimately no code from this text was used, as IPython's
 	system is a separate implementation).
 
 	* IPython/iplib.py (MagicCompleter.python_matches): add new option
 	to control the completion of single/double underscore names
 	separately.  As documented in the example ipytonrc file, the
 	readline_omit__names variable can now be set to 2, to omit even
 	single underscore names.  Thanks to a patch by Brian Wong
 	<BrianWong-AT-AirgoNetworks.Com>.
 	(InteractiveShell.__init__): Fix bug which would cause foo[1] to
 	be autocalled as foo([1]) if foo were callable.  A problem for
 	things which are both callable and implement __getitem__.
 	(init_readline): Fix autoindentation for win32.  Thanks to a patch
 	by Vivian De Smedt <vivian-AT-vdesmedt.com>.
 
 2005-02-12  Fernando Perez  <[e-mail]>
 
 	* IPython/ipmaker.py (make_IPython): Disabled the stout traps
 	which I had written long ago to sort out user error messages which
 	may occur during startup.  This seemed like a good idea initially,
 	but it has proven a disaster in retrospect.  I don't want to
 	change much code for now, so my fix is to set the internal 'debug'
 	flag to true everywhere, whose only job was precisely to control
 	this subsystem.  This closes issue 28 (as well as avoiding all
 	sorts of strange hangups which occur from time to time).
 
 2005-02-07  Fernando Perez  <[e-mail]>
 
 	* IPython/Magic.py (magic_edit): Fix 'ed -p' not working when the
 	previous call produced a syntax error.
 
 	* IPython/OInspect.py (Inspector.pinfo): Fix crash when inspecting
 	classes without constructor.
 
 2005-02-06  Fernando Perez  <[e-mail]>
 
 	* IPython/iplib.py (MagicCompleter.complete): Extend the list of
 	completions with the results of each matcher, so we return results
 	to the user from all namespaces.  This breaks with ipython
 	tradition, but I think it's a nicer behavior.  Now you get all
 	possible completions listed, from all possible namespaces (python,
 	filesystem, magics...)  After a request by John Hunter
 	<jdhunter-AT-nitace.bsd.uchicago.edu>.
 
 2005-02-05  Fernando Perez  <[e-mail]>
 
 	* IPython/Magic.py (magic_prun): Fix bug where prun would fail if
 	the call had quote characters in it (the quotes were stripped).
 
 2005-01-31  Fernando Perez  <[e-mail]>
 
 	* IPython/iplib.py (InteractiveShell.__init__): reduce reliance on
 	Itpl.itpl() to make the code more robust against psyco
 	optimizations.
 
 	* IPython/Itpl.py (Itpl.__str__): Use a _getframe() call instead
 	of causing an exception.  Quicker, cleaner.
 
 2005-01-28  Fernando Perez  <[e-mail]>
 
 	* scripts/ipython_win_post_install.py (install): hardcode
 	sys.prefix+'python.exe' as the executable path.  It turns out that
 	during the post-installation run, sys.executable resolves to the
 	name of the binary installer!  I should report this as a distutils
 	bug, I think.  I updated the .10 release with this tiny fix, to
 	avoid annoying the lists further.
 
 2005-01-27  *** Released version 0.6.10
 
 2005-01-27  Fernando Perez  <[e-mail]>
 
 	* IPython/numutils.py (norm): Added 'inf' as optional name for
 	L-infinity norm, included references to mathworld.com for vector
 	norm definitions.
 	(amin/amax): added amin/amax for array min/max.  Similar to what
 	pylab ships with after the recent reorganization of names.
 	(spike/spike_odd): removed deprecated spike/spike_odd functions.
 
 	* ipython.el: committed Alex's recent fixes and improvements.
 	Tested with python-mode from CVS, and it looks excellent.  Since
 	python-mode hasn't released anything in a while, I'm temporarily
 	putting a copy of today's CVS (v 4.70) of python-mode in:
 	  http://ipython.scipy.org/tmp/python-mode.el
 
 	* scripts/ipython_win_post_install.py (install): Win32 fix to use
 	sys.executable for the executable name, instead of assuming it's
 	called 'python.exe' (the post-installer would have produced broken
 	setups on systems with a differently named python binary).
 
 	* IPython/PyColorize.py (Parser.__call__): change explicit '\n'
 	references to os.linesep, to make the code more
 	platform-independent.  This is also part of the win32 coloring
 	fixes.
 
 	* IPython/genutils.py (page_dumb): Remove attempts to chop long
 	lines, which actually cause coloring bugs because the length of
 	the line is very difficult to correctly compute with embedded
 	escapes.  This was the source of all the coloring problems under
 	Win32.  I think that _finally_, Win32 users have a properly
 	working ipython in all respects.  This would never have happened
 	if not for Gary Bishop and Viktor Ransmayr's great help and work.
 
 2005-01-26  *** Released version 0.6.9
 
 2005-01-25  Fernando Perez  <[e-mail]>
 
 	* setup.py: finally, we have a true Windows installer, thanks to
 	the excellent work of Viktor Ransmayr
 	<viktor.ransmayr-AT-t-online.de>.  The docs have been updated for
 	Windows users.  The setup routine is quite a bit cleaner thanks to
 	this, and the post-install script uses the proper functions to
 	allow a clean de-installation using the standard Windows Control
 	Panel.
 	
 	* IPython/genutils.py (get_home_dir): changed to use the $HOME
 	environment variable under all OSes (including win32) if
 	available.  This will give consistency to win32 users who have set
 	this variable for any reason.  If os.environ['HOME'] fails, the
 	previous policy of using HOMEDRIVE\HOMEPATH kicks in.
 
 2005-01-24  Fernando Perez  <[e-mail]>
 
 	* IPython/numutils.py (empty_like): add empty_like(), similar to
 	zeros_like() but taking advantage of the new empty() Numeric routine.
 
 2005-01-23  *** Released version 0.6.8
 
 2005-01-22  Fernando Perez  <[e-mail]>
 
 	* IPython/Shell.py (MatplotlibShellBase.mplot_exec): I removed the
 	automatic show() calls.  After discussing things with JDH, it
 	turns out there are too many corner cases where this can go wrong.
 	It's best not to try to be 'too smart', and simply have ipython
 	reproduce as much as possible the default behavior of a normal
 	python shell.
 
 	* IPython/iplib.py (InteractiveShell.__init__): Modified the
 	line-splitting regexp and _prefilter() to avoid calling getattr()
 	on assignments.  This closes
 	http://www.scipy.net/roundup/ipython/issue24.  Note that Python's
 	readline uses getattr(), so a simple <TAB> keypress is still
 	enough to trigger getattr() calls on an object.
 
 2005-01-21  Fernando Perez  <[e-mail]>
 
 	* IPython/Shell.py (MatplotlibShellBase.magic_run): Fix the %run
 	docstring under pylab so it doesn't mask the original.
 
 2005-01-21  *** Released version 0.6.7
 
 2005-01-21  Fernando Perez  <[e-mail]>
 
 	* IPython/Shell.py (MTInteractiveShell.runcode): Trap a crash with
 	signal handling for win32 users in multithreaded mode.
 
 2005-01-17  Fernando Perez  <[e-mail]>
 
 	* IPython/OInspect.py (Inspector.pinfo): Fix crash when inspecting
 	instances with no __init__.  After a crash report by Norbert Nemec
 	<Norbert-AT-nemec-online.de>.
 
 2005-01-14  Fernando Perez  <[e-mail]>
 
 	* IPython/ultraTB.py (VerboseTB.text): Fix bug in reporting of
 	names for verbose exceptions, when multiple dotted names and the
 	'parent' object were present on the same line.
 
 2005-01-11  Fernando Perez  <[e-mail]>
 
 	* IPython/genutils.py (flag_calls): new utility to trap and flag
 	calls in functions.  I need it to clean up matplotlib support.
 	Also removed some deprecated code in genutils.
 
 	* IPython/Shell.py (MatplotlibShellBase.mplot_exec): small fix so
 	that matplotlib scripts called with %run, which don't call show()
 	themselves, still have their plotting windows open.
 
 2005-01-05  Fernando Perez  <[e-mail]>
 
 	* IPython/Shell.py (IPShellGTK.__init__): Patch by Andrew Straw
 	<astraw-AT-caltech.edu>, to fix gtk deprecation warnings.
 
 2004-12-19  Fernando Perez  <[e-mail]>
 
 	* IPython/Shell.py (MTInteractiveShell.runcode): Get rid of
 	parent_runcode, which was an eyesore.  The same result can be
 	obtained with Python's regular superclass mechanisms.
 
 2004-12-17  Fernando Perez  <[e-mail]>
 
 	* IPython/Magic.py (Magic.magic_sc): Fix quote stripping problem
 	reported by Prabhu.
 	(Magic.magic_sx): direct all errors to Term.cerr (defaults to
 	sys.stderr) instead of explicitly calling sys.stderr.  This helps
 	maintain our I/O abstractions clean, for future GUI embeddings.
 
 	* IPython/genutils.py (info): added new utility for sys.stderr
 	unified info message handling (thin wrapper around warn()).
 
 	* IPython/ultraTB.py (VerboseTB.text): Fix misreported global
 	composite (dotted) names on verbose exceptions.
 	(VerboseTB.nullrepr): harden against another kind of errors which
 	Python's inspect module can trigger, and which were crashing
 	IPython.  Thanks to a report by Marco Lombardi
 	<mlombard-AT-ma010192.hq.eso.org>.
 
 2004-12-13  *** Released version 0.6.6
 
 2004-12-12  Fernando Perez  <[e-mail]>
 
 	* IPython/Shell.py (IPShellGTK.mainloop): catch RuntimeErrors
 	generated by pygtk upon initialization if it was built without
 	threads (for matplotlib users).  After a crash reported by
 	Leguijt, Jaap J SIEP-EPT-RES <Jaap.Leguijt-AT-shell.com>.
 
 	* IPython/ipmaker.py (make_IPython): fix small bug in the
 	import_some parameter for multiple imports.
 
 	* IPython/iplib.py (ipmagic): simplified the interface of
 	ipmagic() to take a single string argument, just as it would be
 	typed at the IPython cmd line.
 	(ipalias): Added new ipalias() with an interface identical to
 	ipmagic().  This completes exposing a pure python interface to the
 	alias and magic system, which can be used in loops or more complex
 	code where IPython's automatic line mangling is not active.
 
 	* IPython/genutils.py (timing): changed interface of timing to
 	simply run code once, which is the most common case.  timings()
 	remains unchanged, for the cases where you want multiple runs.
 
 	* IPython/Shell.py (MatplotlibShellBase._matplotlib_config): Fix a
 	bug where Python2.2 crashes with exec'ing code which does not end
 	in a single newline.  Python 2.3 is OK, so I hadn't noticed this
 	before.
 
 2004-12-10  Fernando Perez  <[e-mail]>
 
 	* IPython/Magic.py (Magic.magic_prun): changed name of option from
 	-t to -T, to accomodate the new -t flag in %run (the %run and
 	%prun options are kind of intermixed, and it's not easy to change
 	this with the limitations of python's getopt).
 
 	* IPython/Magic.py (Magic.magic_run): Added new -t option to time
 	the execution of scripts.  It's not as fine-tuned as timeit.py,
 	but it works from inside ipython (and under 2.2, which lacks
 	timeit.py).  Optionally a number of runs > 1 can be given for
 	timing very short-running code.
 
 	* IPython/genutils.py (uniq_stable): new routine which returns a
 	list of unique elements in any iterable, but in stable order of
 	appearance.  I needed this for the ultraTB fixes, and it's a handy
 	utility.
 
 	* IPython/ultraTB.py (VerboseTB.text): Fix proper reporting of
 	dotted names in Verbose exceptions.  This had been broken since
 	the very start, now x.y will properly be printed in a Verbose
 	traceback, instead of x being shown and y appearing always as an
 	'undefined global'.  Getting this to work was a bit tricky,
 	because by default python tokenizers are stateless.  Saved by
 	python's ability to easily add a bit of state to an arbitrary
 	function (without needing to build a full-blown callable object).
 
 	Also big cleanup of this code, which had horrendous runtime
 	lookups of zillions of attributes for colorization.  Moved all
 	this code into a few templates, which make it cleaner and quicker.
 
 	Printout quality was also improved for Verbose exceptions: one
 	variable per line, and memory addresses are printed (this can be
 	quite handy in nasty debugging situations, which is what Verbose
 	is for).
 
 	* IPython/ipmaker.py (make_IPython): Do NOT execute files named in
 	the command line as scripts to be loaded by embedded instances.
 	Doing so has the potential for an infinite recursion if there are
 	exceptions thrown in the process.  This fixes a strange crash
 	reported by Philippe MULLER <muller-AT-irit.fr>.
 
 2004-12-09  Fernando Perez  <[e-mail]>
 
 	* IPython/Shell.py (MatplotlibShellBase.use): Change pylab support
 	to reflect new names in matplotlib, which now expose the
 	matlab-compatible interface via a pylab module instead of the
 	'matlab' name.  The new code is backwards compatible, so users of
 	all matplotlib versions are OK.  Patch by J. Hunter.
 
 	* IPython/OInspect.py (Inspector.pinfo): Add to object? printing
 	of __init__ docstrings for instances (class docstrings are already
 	automatically printed).  Instances with customized docstrings
 	(indep. of the class) are also recognized and all 3 separate
 	docstrings are printed (instance, class, constructor).  After some
 	comments/suggestions by J. Hunter.
 
 2004-12-05  Fernando Perez  <[e-mail]>
 
 	* IPython/iplib.py (MagicCompleter.complete): Remove annoying
 	warnings when tab-completion fails and triggers an exception.
 
 2004-12-03  Fernando Perez  <[e-mail]>
 
 	* IPython/Magic.py (magic_prun): Fix bug where an exception would
 	be triggered when using 'run -p'.  An incorrect option flag was
 	being set ('d' instead of 'D').
 	(manpage): fix missing escaped \- sign.
 
 2004-11-30  *** Released version 0.6.5
 
 2004-11-30  Fernando Perez  <[e-mail]>
 
 	* IPython/Magic.py (Magic.magic_run): Fix bug in breakpoint
 	setting with -d option.
 
 	* setup.py (docfiles): Fix problem where the doc glob I was using
 	was COMPLETELY BROKEN.  It was giving the right files by pure
 	accident, but failed once I tried to include ipython.el.  Note:
 	glob() does NOT allow you to do exclusion on multiple endings!
 
 2004-11-29  Fernando Perez  <[e-mail]>
 
 	* IPython/usage.py (__doc__): cleaned up usage docstring, by using
 	the manpage as the source.  Better formatting & consistency.
 
 	* IPython/Magic.py (magic_run): Added new -d option, to run
 	scripts under the control of the python pdb debugger.  Note that
 	this required changing the %prun option -d to -D, to avoid a clash
 	(since %run must pass options to %prun, and getopt is too dumb to
 	handle options with string values with embedded spaces).  Thanks
 	to a suggestion by Matthew Arnison <maffew-AT-cat.org.au>.
 	(magic_who_ls): added type matching to %who and %whos, so that one
 	can filter their output to only include variables of certain
 	types.  Another suggestion by Matthew.
 	(magic_whos): Added memory summaries in kb and Mb for arrays.
 	(magic_who): Improve formatting (break lines every 9 vars).
 
 2004-11-28  Fernando Perez  <[e-mail]>
 
 	* IPython/Logger.py (Logger.log): Fix bug in syncing the input
 	cache when empty lines were present.
 
 2004-11-24  Fernando Perez  <[e-mail]>
 
 	* IPython/usage.py (__doc__): document the re-activated threading
 	options for WX and GTK.
 
 2004-11-23  Fernando Perez  <[e-mail]>
 
 	* IPython/Shell.py (start): Added Prabhu's big patch to reactivate
 	the -wthread and -gthread options, along with a new -tk one to try
 	and coordinate Tk threading with wx/gtk.  The tk support is very
 	platform dependent, since it seems to require Tcl and Tk to be
 	built with threads (Fedora1/2 appears NOT to have it, but in
 	Prabhu's Debian boxes it works OK).  But even with some Tk
 	limitations, this is a great improvement.
 
 	* IPython/Prompts.py (prompt_specials_color): Added \t for time
 	info in user prompts.  Patch by Prabhu.
 
 2004-11-18  Fernando Perez  <[e-mail]>
 
 	* IPython/genutils.py (ask_yes_no): Add check for a max of 20
 	EOFErrors and bail, to avoid infinite loops if a non-terminating
 	file is fed into ipython.  Patch submitted in issue 19 by user,
 	many thanks.
 
 	* IPython/iplib.py (InteractiveShell.handle_auto): do NOT trigger
 	autoquote/parens in continuation prompts, which can cause lots of
 	problems.  Closes roundup issue 20.
 
 2004-11-17  Fernando Perez  <[e-mail]>
 
 	* debian/control (Build-Depends-Indep): Fix dpatch dependency,
 	reported as debian bug #280505.  I'm not sure my local changelog
 	entry has the proper debian format (Jack?).
 
 2004-11-08  *** Released version 0.6.4
 
 2004-11-08  Fernando Perez  <[e-mail]>
 
 	* IPython/iplib.py (init_readline): Fix exit message for Windows
 	when readline is active.  Thanks to a report by Eric Jones
 	<eric-AT-enthought.com>.
 
 2004-11-07  Fernando Perez  <[e-mail]>
 
 	* IPython/genutils.py (page): Add a trap for OSError exceptions,
 	sometimes seen by win2k/cygwin users.
 
 2004-11-06  Fernando Perez  <[e-mail]>
 
 	* IPython/iplib.py (interact): Change the handling of %Exit from
 	trying to propagate a SystemExit to an internal ipython flag.
 	This is less elegant than using Python's exception mechanism, but
 	I can't get that to work reliably with threads, so under -pylab
 	%Exit was hanging IPython.  Cross-thread exception handling is
 	really a bitch.  Thaks to a bug report by Stephen Walton
 	<stephen.walton-AT-csun.edu>.
 
 2004-11-04  Fernando Perez  <[e-mail]>
 
 	* IPython/iplib.py (raw_input_original): store a pointer to the
 	true raw_input to harden against code which can modify it
 	(wx.py.PyShell does this and would otherwise crash ipython).
 	Thanks to a bug report by Jim Flowers <james.flowers-AT-lgx.com>.
 
 	* IPython/Shell.py (MTInteractiveShell.runsource): Cleaner fix for
 	Ctrl-C problem, which does not mess up the input line.
 
 2004-11-03  Fernando Perez  <[e-mail]>
 
 	* IPython/Release.py: Changed licensing to BSD, in all files.
 	(name): lowercase name for tarball/RPM release.
 
 	* IPython/OInspect.py (getdoc): wrap inspect.getdoc() safely for
 	use throughout ipython.
 
 	* IPython/Magic.py (Magic._ofind): Switch to using the new
 	OInspect.getdoc() function.
 
 	* IPython/Shell.py (sigint_handler): Hack to ignore the execution
 	of the line currently being canceled via Ctrl-C.  It's extremely
 	ugly, but I don't know how to do it better (the problem is one of
 	handling cross-thread exceptions).
 
 2004-10-28  Fernando Perez  <[e-mail]>
 
 	* IPython/Shell.py (signal_handler): add signal handlers to trap
 	SIGINT and SIGSEGV in threaded code properly.  Thanks to a bug
 	report by Francesc Alted.
 
 2004-10-21  Fernando Perez  <[e-mail]>
 
 	* IPython/Extensions/InterpreterExec.py (prefilter_shell): Fix @
 	to % for pysh syntax extensions.
 
 2004-10-09  Fernando Perez  <[e-mail]>
 
 	* IPython/Magic.py (Magic.magic_whos): modify output of Numeric
 	arrays to print a more useful summary, without calling str(arr).
 	This avoids the problem of extremely lengthy computations which
 	occur if arr is large, and appear to the user as a system lockup
 	with 100% cpu activity.  After a suggestion by Kristian Sandberg
 	<[e-mail]>.
 	(Magic.__init__): fix bug in global magic escapes not being
 	correctly set.
 
 2004-10-08  Fernando Perez  <[e-mail]>
 
 	* IPython/Magic.py (__license__): change to absolute imports of
 	ipython's own internal packages, to start adapting to the absolute
 	import requirement of PEP-328.
 
 	* IPython/genutils.py (__author__): Fix coding to utf-8 on all
 	files, and standardize author/license marks through the Release
 	module instead of having per/file stuff (except for files with
 	particular licenses, like the MIT/PSF-licensed codes).
 
 	* IPython/Debugger.py: remove dead code for python 2.1
 
 2004-10-04  Fernando Perez  <[e-mail]>
 
 	* IPython/iplib.py (ipmagic): New function for accessing magics
 	via a normal python function call.
 
 	* IPython/Magic.py (Magic.magic_magic): Change the magic escape
 	from '@' to '%', to accomodate the new @decorator syntax of python
 	2.4.
 
 2004-09-29  Fernando Perez  <[e-mail]>
 
 	* IPython/Shell.py (MatplotlibShellBase.use): Added a wrapper to
 	matplotlib.use to prevent running scripts which try to switch
 	interactive backends from within ipython.  This will just crash
 	the python interpreter, so we can't allow it (but a detailed error
 	is given to the user).
 	
 2004-09-28  Fernando Perez  <[e-mail]>
 
 	* IPython/Shell.py (MatplotlibShellBase.mplot_exec):
 	matplotlib-related fixes so that using @run with non-matplotlib
 	scripts doesn't pop up spurious plot windows.  This requires
 	matplotlib >= 0.63, where I had to make some changes as well.
 
 	* IPython/ipmaker.py (make_IPython): update version requirement to
 	python 2.2.
 
 	* IPython/iplib.py (InteractiveShell.mainloop): Add an optional
 	banner arg for embedded customization.
 
 	* IPython/Magic.py (Magic.__init__): big cleanup to remove all
 	explicit uses of __IP as the IPython's instance name.  Now things
 	are properly handled via the shell.name value.  The actual code
 	is a bit ugly b/c I'm doing it via a global in Magic.py, but this
 	is much better than before.  I'll clean things completely when the
 	magic stuff gets a real overhaul.
 
 	* ipython.1: small fixes, sent in by Jack Moffit.  He also sent in
 	minor changes to debian dir.
 
 	* IPython/iplib.py (InteractiveShell.__init__): Fix adding a
 	pointer to the shell itself in the interactive namespace even when
 	a user-supplied dict is provided.  This is needed for embedding
 	purposes (found by tests with Michel Sanner).
 
 2004-09-27  Fernando Perez  <[e-mail]>
 
 	* IPython/UserConfig/ipythonrc: remove []{} from
 	readline_remove_delims, so that things like [modname.<TAB> do
 	proper completion.  This disables [].TAB, but that's a less common
 	case than module names in list comprehensions, for example.
 	Thanks to a report by Andrea Riciputi.
 
 2004-09-09  Fernando Perez  <[e-mail]>
 
 	* IPython/Shell.py (IPShellGTK.mainloop): reorder to avoid
 	blocking problems in win32 and osx.  Fix by John.
 
 2004-09-08  Fernando Perez  <[e-mail]>
 
 	* IPython/Shell.py (IPShellWX.OnInit): Fix output redirection bug
 	for Win32 and OSX.  Fix by John Hunter.
 
 2004-08-30  *** Released version 0.6.3
 
 2004-08-30  Fernando Perez  <[e-mail]>
 
 	* setup.py (isfile): Add manpages to list of dependent files to be
 	updated.
 
 2004-08-27  Fernando Perez  <[e-mail]>
 
 	* IPython/Shell.py (start): I've disabled -wthread and -gthread
 	for now.  They don't really work with standalone WX/GTK code
 	(though matplotlib IS working fine with both of those backends).
 	This will neeed much more testing.  I disabled most things with
 	comments, so turning it back on later should be pretty easy.
 
 	* IPython/iplib.py (InteractiveShell.__init__): Fix accidental
 	autocalling of expressions like r'foo', by modifying the line
 	split regexp.  Closes
 	http://www.scipy.net/roundup/ipython/issue18, reported by Nicholas
 	Riley <ipythonbugs-AT-sabi.net>.
 	(InteractiveShell.mainloop): honor --nobanner with banner
 	extensions.
 
 	* IPython/Shell.py: Significant refactoring of all classes, so
 	that we can really support ALL matplotlib backends and threading
 	models (John spotted a bug with Tk which required this).  Now we
 	should support single-threaded, WX-threads and GTK-threads, both
 	for generic code and for matplotlib.
 
 	* IPython/ipmaker.py (__call__): Changed -mpthread option to
 	-pylab, to simplify things for users.  Will also remove the pylab
 	profile, since now all of matplotlib configuration is directly
 	handled here.  This also reduces startup time.
 
 	* IPython/Shell.py (IPShellGTK.run): Fixed bug where mainloop() of
 	shell wasn't being correctly called.  Also in IPShellWX.
 
 	* IPython/iplib.py (InteractiveShell.__init__): Added option to
 	fine-tune banner.
 
 	* IPython/numutils.py (spike): Deprecate these spike functions,
 	delete (long deprecated) gnuplot_exec handler.
 
 2004-08-26  Fernando Perez  <[e-mail]>
 
 	* ipython.1: Update for threading options, plus some others which
 	were missing.
 
 	* IPython/ipmaker.py (__call__): Added -wthread option for
 	wxpython thread handling.  Make sure threading options are only
 	valid at the command line.
 
 	* scripts/ipython: moved shell selection into a factory function
 	in Shell.py, to keep the starter script to a minimum.
 
 2004-08-25  Fernando Perez  <[e-mail]>
 
 	* IPython/Shell.py (IPShellWX.wxexit): fixes to WX threading, by
 	John.  Along with some recent changes he made to matplotlib, the
 	next versions of both systems should work very well together.
 
 2004-08-24  Fernando Perez  <[e-mail]>
 
 	* IPython/Magic.py (Magic.magic_prun): cleanup some dead code.  I
 	tried to switch the profiling to using hotshot, but I'm getting
 	strange errors from prof.runctx() there.  I may be misreading the
 	docs, but it looks weird.  For now the profiling code will
 	continue to use the standard profiler.
 
 2004-08-23  Fernando Perez  <[e-mail]>
 
 	* IPython/Shell.py (IPShellWX.__init__): Improvements to the WX
 	threaded shell, by John Hunter.  It's not quite ready yet, but
 	close.
 
 2004-08-22  Fernando Perez  <[e-mail]>
 
 	* IPython/iplib.py (InteractiveShell.interact): tab cleanups, also
 	in Magic and ultraTB.
 
 	* ipython.1: document threading options in manpage.
 
 	* scripts/ipython: Changed name of -thread option to -gthread,
 	since this is GTK specific.  I want to leave the door open for a
 	-wthread option for WX, which will most likely be necessary.  This
 	change affects usage and ipmaker as well.
 
 	* IPython/Shell.py (matplotlib_shell): Add a factory function to
 	handle the matplotlib shell issues.  Code by John Hunter
 	<jdhunter-AT-nitace.bsd.uchicago.edu>.
 	(IPShellMatplotlibWX.__init__): Rudimentary WX support.  It's
 	broken (and disabled for end users) for now, but it puts the
 	infrastructure in place.
 
 2004-08-21  Fernando Perez  <[e-mail]>
 
 	* ipythonrc-pylab: Add matplotlib support.
 
 	* matplotlib_config.py: new files for matplotlib support, part of
 	the pylab profile.
 
 	* IPython/usage.py (__doc__): documented the threading options.
 
 2004-08-20  Fernando Perez  <[e-mail]>
 
 	* ipython: Modified the main calling routine to handle the -thread
 	and -mpthread options.  This needs to be done as a top-level hack,
 	because it determines which class to instantiate for IPython
 	itself.
 
 	* IPython/Shell.py (MTInteractiveShell.__init__): New set of
 	classes to support multithreaded GTK operation without blocking,
 	and matplotlib with all backends.  This is a lot of still very
 	experimental code, and threads are tricky.  So it may still have a
 	few rough edges...  This code owes a lot to
 	http://aspn.activestate.com/ASPN/Cookbook/Python/Recipe/65109, by
 	Brian # McErlean and John Finlay, to Antoon Pardon for fixes, and
 	to John Hunter for all the matplotlib work.
 
 	* IPython/ipmaker.py (__call__): Added -thread and -mpthread
 	options for gtk thread and matplotlib support.
 
 2004-08-16  Fernando Perez  <[e-mail]>
 
 	* IPython/iplib.py (InteractiveShell.__init__): don't trigger
 	autocall for things like p*q,p/q,p+q,p-q, when p is callable.  Bug
 	reported by Stephen Walton <stephen.walton-AT-csun.edu>.
 
 2004-08-11  Fernando Perez  <[e-mail]>
 
 	* setup.py (isfile): Fix build so documentation gets updated for
 	rpms (it was only done for .tgz builds).
 
 2004-08-10  Fernando Perez  <[e-mail]>
 
 	* genutils.py (Term): Fix misspell of stdin stream (sin->cin).
 
 	* iplib.py : Silence syntax error exceptions in tab-completion.
 	
 2004-08-05  Fernando Perez  <[e-mail]>
 
 	* IPython/Prompts.py (Prompt2.set_colors): Fix incorrectly set
 	'color off' mark for continuation prompts.  This was causing long
 	continuation lines to mis-wrap.
 
 2004-08-01  Fernando Perez  <[e-mail]>
 
 	* IPython/ipmaker.py (make_IPython): Allow the shell class used
 	for building ipython to be a parameter.  All this is necessary
 	right now to have a multithreaded version, but this insane
 	non-design will be cleaned up soon.  For now, it's a hack that
 	works.
 
 	* IPython/Shell.py (IPShell.__init__): Stop using mutable default
 	args in various places.  No bugs so far, but it's a dangerous
 	practice.
 
 2004-07-31  Fernando Perez  <[e-mail]>
 
 	* IPython/iplib.py (complete): ignore SyntaxError exceptions to
 	fix completion of files with dots in their names under most
 	profiles (pysh was OK because the completion order is different).
 
 2004-07-27  Fernando Perez  <[e-mail]>
 
 	* IPython/iplib.py (InteractiveShell.__init__): build dict of
 	keywords manually, b/c the one in keyword.py was removed in python
 	2.4.  Patch by Anakim Border <aborder-AT-users.sourceforge.net>.
 	This is NOT a bug under python 2.3 and earlier.
 
 2004-07-26  Fernando Perez  <[e-mail]>
 
 	* IPython/ultraTB.py (VerboseTB.text): Add another
 	linecache.checkcache() call to try to prevent inspect.py from
 	crashing under python 2.3.  I think this fixes
 	http://www.scipy.net/roundup/ipython/issue17.
 
 2004-07-26  *** Released version 0.6.2
 
 2004-07-26  Fernando Perez  <[e-mail]>
 
 	* IPython/Magic.py (Magic.magic_cd): Fix bug where 'cd -N' would
 	fail for any number.
 	(Magic.magic_bookmark): Fix bug where 'bookmark -l' would fail for
 	empty bookmarks.
 
 2004-07-26  *** Released version 0.6.1
 
 2004-07-26  Fernando Perez  <[e-mail]>
 
 	* ipython_win_post_install.py (run): Added pysh shortcut for Windows.
 
 	* IPython/iplib.py (protect_filename): Applied Ville's patch for
 	escaping '()[]{}' in filenames.
 
 	* IPython/Magic.py (shlex_split): Fix handling of '*' and '?' for
 	Python 2.2 users who lack a proper shlex.split.
 
 2004-07-19  Fernando Perez  <[e-mail]>
 
 	* IPython/iplib.py (InteractiveShell.init_readline): Add support
 	for reading readline's init file.  I follow the normal chain:
 	$INPUTRC is honored, otherwise ~/.inputrc is used.  Thanks to a
 	report by Mike Heeter.  This closes
 	http://www.scipy.net/roundup/ipython/issue16.
 
 2004-07-18  Fernando Perez  <[e-mail]>
 
 	* IPython/iplib.py (__init__): Add better handling of '\' under
 	Win32 for filenames.  After a patch by Ville.
 
 2004-07-17  Fernando Perez  <[e-mail]>
 
 	* IPython/iplib.py (InteractiveShell._prefilter): fix bug where
 	autocalling would be triggered for 'foo is bar' if foo is
 	callable.  I also cleaned up the autocall detection code to use a
 	regexp, which is faster.  Bug reported by Alexander Schmolck.
 
 	* IPython/Magic.py (Magic.magic_pinfo): Fix bug where strings with
 	'?' in them would confuse the help system.  Reported by Alex
 	Schmolck.
 
 2004-07-16  Fernando Perez  <[e-mail]>
 
 	* IPython/GnuplotInteractive.py (__all__): added plot2.
 
 	* IPython/Gnuplot2.py (Gnuplot.plot2): added new function for
 	plotting dictionaries, lists or tuples of 1d arrays.
 
 	* IPython/Magic.py (Magic.magic_hist): small clenaups and
 	optimizations.
 
 	* IPython/iplib.py:Remove old Changelog info for cleanup.  This is
 	the information which was there from Janko's original IPP code:
 
 	03.05.99 20:53 porto.ifm.uni-kiel.de
 	--Started changelog.
 	--make clear do what it say it does
 	--added pretty output of lines from inputcache
 	--Made Logger a mixin class, simplifies handling of switches
 	--Added own completer class. .string<TAB> expands to last history
 	line which starts with string.  The new expansion is also present
 	with Ctrl-r from the readline library.  But this shows, who this
 	can be done for other cases.
 	--Added convention that all shell functions should accept a
 	parameter_string This opens the door for different behaviour for
 	each function. @cd is a good example of this.
 
 	04.05.99 12:12 porto.ifm.uni-kiel.de
 	--added logfile rotation
 	--added new mainloop method which freezes first the namespace
 
 	07.05.99 21:24 porto.ifm.uni-kiel.de
 	--added the docreader classes. Now there is a help system.
 	-This is only a first try. Currently it's not easy to put new
 	stuff in the indices. But this is the way to go. Info would be
 	better, but HTML is every where and not everybody has an info
 	system installed and it's not so easy to change html-docs to info.
 	--added global logfile option
 	--there is now a hook for object inspection method pinfo needs to
 	be provided for this. Can be reached by two '??'.
 
 	08.05.99 20:51 porto.ifm.uni-kiel.de
 	--added a README
 	--bug in rc file. Something has changed so functions in the rc
 	file need to reference the shell and not self. Not clear if it's a
 	bug or feature.
 	--changed rc file for new behavior
 
 2004-07-15  Fernando Perez  <[e-mail]>
 
 	* IPython/Logger.py (Logger.log): fixed recent bug where the input
 	cache was falling out of sync in bizarre manners when multi-line
 	input was present.  Minor optimizations and cleanup.
 
 	(Logger): Remove old Changelog info for cleanup.  This is the
 	information which was there from Janko's original code:
 
 	Changes to Logger: - made the default log filename a parameter
 
 	- put a check for lines beginning with !@? in log(). Needed
 	(even if the handlers properly log their lines) for mid-session
 	logging activation to work properly. Without this, lines logged
 	in mid session, which get read from the cache, would end up
 	'bare' (with !@? in the open) in the log. Now they are caught
 	and prepended with a #.
 
 	* IPython/iplib.py (InteractiveShell.init_readline): added check
 	in case MagicCompleter fails to be defined, so we don't crash.
 
 2004-07-13  Fernando Perez  <[e-mail]>
 
 	* IPython/Gnuplot2.py (Gnuplot.hardcopy): add automatic generation
 	of EPS if the requested filename ends in '.eps'.
 
 2004-07-04  Fernando Perez  <[e-mail]>
 
 	* IPython/iplib.py (InteractiveShell.handle_shell_escape): Fix
 	escaping of quotes when calling the shell.
 
 2004-07-02  Fernando Perez  <[e-mail]>
 
 	* IPython/Prompts.py (CachedOutput.update): Fix problem with
 	gettext not working because we were clobbering '_'.  Fixes
 	http://www.scipy.net/roundup/ipython/issue6.
 
 2004-07-01  Fernando Perez  <[e-mail]>
 
 	* IPython/Magic.py (Magic.magic_cd): integrated bookmark handling
 	into @cd.  Patch by Ville.
 
 	* IPython/iplib.py (InteractiveShell.post_config_initialization):
 	new function to store things after ipmaker runs.  Patch by Ville.
 	Eventually this will go away once ipmaker is removed and the class
 	gets cleaned up, but for now it's ok.  Key functionality here is
 	the addition of the persistent storage mechanism, a dict for
 	keeping data across sessions (for now just bookmarks, but more can
 	be implemented later).
 
 	* IPython/Magic.py (Magic.magic_bookmark): New bookmark system,
 	persistent across sections.  Patch by Ville, I modified it
 	soemwhat to allow bookmarking arbitrary dirs other than CWD.  Also
 	added a '-l' option to list all bookmarks.
 
 	* IPython/iplib.py (InteractiveShell.atexit_operations): new
 	center for cleanup.  Registered with atexit.register().  I moved
 	here the old exit_cleanup().  After a patch by Ville.
 
 	* IPython/Magic.py (get_py_filename): added '~' to the accepted
 	characters in the hacked shlex_split for python 2.2.
 
 	* IPython/iplib.py (file_matches): more fixes to filenames with
 	whitespace in them.  It's not perfect, but limitations in python's
 	readline make it impossible to go further.
 
 2004-06-29  Fernando Perez  <[e-mail]>
 
 	* IPython/iplib.py (file_matches): escape whitespace correctly in
 	filename completions.  Bug reported by Ville.
 
 2004-06-28  Fernando Perez  <[e-mail]>
 
 	* IPython/ipmaker.py (__call__): Added per-profile histories.  Now
 	the history file will be called 'history-PROFNAME' (or just
 	'history' if no profile is loaded).  I was getting annoyed at
 	getting my Numerical work history clobbered by pysh sessions.
 
 	* IPython/iplib.py (InteractiveShell.__init__): Internal
 	getoutputerror() function so that we can honor the system_verbose
 	flag for _all_ system calls.  I also added escaping of #
 	characters here to avoid confusing Itpl.
 
 	* IPython/Magic.py (shlex_split): removed call to shell in
 	parse_options and replaced it with shlex.split().  The annoying
 	part was that in Python 2.2, shlex.split() doesn't exist, so I had
 	to backport it from 2.3, with several frail hacks (the shlex
 	module is rather limited in 2.2).  Thanks to a suggestion by Ville
 	Vainio <[e-mail]>.  For Python 2.3 there should be no
 	problem.
 	
 	(Magic.magic_system_verbose): new toggle to print the actual
 	system calls made by ipython.  Mainly for debugging purposes.
 
 	* IPython/GnuplotRuntime.py (gnu_out): fix bug for cygwin, which
 	doesn't support persistence.  Reported (and fix suggested) by
 	Travis Caldwell <[e-mail]>.
 
 2004-06-26  Fernando Perez  <[e-mail]>
 
 	* IPython/Logger.py (Logger.log): fix to handle correctly empty
 	continue prompts.
 
 	* IPython/Extensions/InterpreterExec.py (pysh): moved the pysh()
 	function (basically a big docstring) and a few more things here to
 	speedup startup. pysh.py is now very lightweight.  We want because
 	it gets execfile'd, while InterpreterExec gets imported, so
 	byte-compilation saves time.
 
 2004-06-25  Fernando Perez  <[e-mail]>
 
 	* IPython/Magic.py (Magic.magic_cd): Fixed to restore usage of 'cd
 	-NUM', which was recently broken.
 
 	* IPython/iplib.py (InteractiveShell.handle_shell_escape): allow !
 	in multi-line input (but not !!, which doesn't make sense there).
 
 	* IPython/UserConfig/ipythonrc: made autoindent on by default.
 	It's just too useful, and people can turn it off in the less
 	common cases where it's a problem.
 
 2004-06-24  Fernando Perez  <[e-mail]>
 
 	* IPython/iplib.py (InteractiveShell._prefilter): big change -
 	special syntaxes (like alias calling) is now allied in multi-line
 	input.  This is still _very_ experimental, but it's necessary for
 	efficient shell usage combining python looping syntax with system
 	calls.  For now it's restricted to aliases, I don't think it
 	really even makes sense to have this for magics.
 
 2004-06-23  Fernando Perez  <[e-mail]>
 
 	* IPython/Extensions/InterpreterExec.py (prefilter_shell): Added
 	$var=cmd <=> @sc var=cmd and  $$var=cmd <=> @sc -l var=cmd.
 
 	* IPython/Magic.py (Magic.magic_rehashx): modified to handle
 	extensions under Windows (after code sent by Gary Bishop).  The
 	extensions considered 'executable' are stored in IPython's rc
 	structure as win_exec_ext.
 
 	* IPython/genutils.py (shell): new function, like system() but
 	without return value.  Very useful for interactive shell work.
 
 	* IPython/Magic.py (Magic.magic_unalias): New @unalias function to
 	delete aliases.
 
 	* IPython/iplib.py (InteractiveShell.alias_table_update): make
 	sure that the alias table doesn't contain python keywords.
 
 2004-06-21  Fernando Perez  <[e-mail]>
 
 	* IPython/Magic.py (Magic.magic_rehash): Fix crash when
 	non-existent items are found in $PATH.  Reported by Thorsten.
 
 2004-06-20  Fernando Perez  <[e-mail]>
 
 	* IPython/iplib.py (complete): modified the completer so that the
 	order of priorities can be easily changed at runtime.
 
 	* IPython/Extensions/InterpreterExec.py (prefilter_shell):
 	Modified to auto-execute all lines beginning with '~', '/' or '.'.
 
 	* IPython/Magic.py (Magic.magic_sx): modified @sc and @sx to
 	expand Python variables prepended with $ in all system calls.  The
 	same was done to InteractiveShell.handle_shell_escape.  Now all
 	system access mechanisms (!, !!, @sc, @sx and aliases) allow the
 	expansion of python variables and expressions according to the
 	syntax of PEP-215 - http://www.python.org/peps/pep-0215.html.
 
 	Though PEP-215 has been rejected, a similar (but simpler) one
 	seems like it will go into Python 2.4, PEP-292 -
 	http://www.python.org/peps/pep-0292.html.
 
 	I'll keep the full syntax of PEP-215, since IPython has since the
 	start used Ka-Ping Yee's reference implementation discussed there
 	(Itpl), and I actually like the powerful semantics it offers.
 
 	In order to access normal shell variables, the $ has to be escaped
 	via an extra $.  For example:
 
 	In [7]: PATH='a python variable'
 
 	In [8]: !echo $PATH
 	a python variable
 
 	In [9]: !echo $$PATH
 	/usr/local/lf9560/bin:/usr/local/intel/compiler70/ia32/bin:...
 
 	(Magic.parse_options): escape $ so the shell doesn't evaluate
 	things prematurely.
 
 	* IPython/iplib.py (InteractiveShell.call_alias): added the
 	ability for aliases to expand python variables via $.
 
 	* IPython/Magic.py (Magic.magic_rehash): based on the new alias
 	system, now there's a @rehash/@rehashx pair of magics.  These work
 	like the csh rehash command, and can be invoked at any time.  They
 	build a table of aliases to everything in the user's $PATH
 	(@rehash uses everything, @rehashx is slower but only adds
 	executable files).  With this, the pysh.py-based shell profile can
 	now simply call rehash upon startup, and full access to all
 	programs in the user's path is obtained.
 
 	* IPython/iplib.py (InteractiveShell.call_alias): The new alias
 	functionality is now fully in place.  I removed the old dynamic
 	code generation based approach, in favor of a much lighter one
 	based on a simple dict.  The advantage is that this allows me to
 	now have thousands of aliases with negligible cost (unthinkable
 	with the old system).
 
 2004-06-19  Fernando Perez  <[e-mail]>
 
 	* IPython/iplib.py (__init__): extended MagicCompleter class to
 	also complete (last in priority) on user aliases.
 
 	* IPython/Itpl.py (Itpl.__str__): fixed order of globals/locals in
 	call to eval.
 	(ItplNS.__init__): Added a new class which functions like Itpl,
 	but allows configuring the namespace for the evaluation to occur
 	in.
 
 2004-06-18  Fernando Perez  <[e-mail]>
 
 	* IPython/iplib.py (InteractiveShell.runcode): modify to print a
 	better message when 'exit' or 'quit' are typed (a common newbie
 	confusion).
 
 	* IPython/Magic.py (Magic.magic_colors): Added the runtime color
 	check for Windows users.
 
 	* IPython/iplib.py (InteractiveShell.user_setup): removed
 	disabling of colors for Windows.  I'll test at runtime and issue a
 	warning if Gary's readline isn't found, as to nudge users to
 	download it.
 
 2004-06-16  Fernando Perez  <[e-mail]>
 
 	* IPython/genutils.py (Stream.__init__): changed to print errors
 	to sys.stderr.  I had a circular dependency here.  Now it's
 	possible to run ipython as IDLE's shell (consider this pre-alpha,
 	since true stdout things end up in the starting terminal instead
 	of IDLE's out).
 
 	* IPython/Prompts.py (Prompt2.set_colors): prevent crashes for
 	users who haven't # updated their prompt_in2 definitions.  Remove
 	eventually.
 	(multiple_replace): added credit to original ASPN recipe.
 
 2004-06-15  Fernando Perez  <[e-mail]>
 
 	* IPython/iplib.py (InteractiveShell.__init__): add 'cp' to the
 	list of auto-defined aliases.
 
 2004-06-13  Fernando Perez  <[e-mail]>
 
 	* setup.py (scriptfiles): Don't trigger win_post_install unless an
 	install was really requested (so setup.py can be used for other
 	things under Windows).
 
 2004-06-10  Fernando Perez  <[e-mail]>
 
 	* IPython/Logger.py (Logger.create_log): Manually remove any old
 	backup, since os.remove may fail under Windows.  Fixes bug
 	reported by Thorsten.
 
 2004-06-09  Fernando Perez  <[e-mail]>
 
 	* examples/example-embed.py: fixed all references to %n (replaced
 	with \\# for ps1/out prompts and with \\D for ps2 prompts).  Done
 	for all examples and the manual as well.
 
 2004-06-08  Fernando Perez  <[e-mail]>
 
 	* IPython/Prompts.py (Prompt2.set_p_str): fixed all prompt
 	alignment and color management.  All 3 prompt subsystems now
 	inherit from BasePrompt.
 
 	* tools/release: updates for windows installer build and tag rpms
 	with python version (since paths are fixed).
 
 	* IPython/UserConfig/ipythonrc: modified to use \# instead of %n,
 	which will become eventually obsolete.  Also fixed the default
 	prompt_in2 to use \D, so at least new users start with the correct
 	defaults.
 	WARNING: Users with existing ipythonrc files will need to apply
 	this fix manually!
 
 	* setup.py: make windows installer (.exe).  This is finally the
 	integration of an old patch by Cory Dodt <dodt-AT-fcoe.k12.ca.us>,
 	which I hadn't included because it required Python 2.3 (or recent
 	distutils).
 
 	* IPython/usage.py (__doc__): update docs (and manpage) to reflect
 	usage of new '\D' escape.
 
 	* IPython/Prompts.py (ROOT_SYMBOL): Small fix for Windows (which
 	lacks os.getuid())
 	(CachedOutput.set_colors): Added the ability to turn coloring
 	on/off with @colors even for manually defined prompt colors.  It
 	uses a nasty global, but it works safely and via the generic color
 	handling mechanism.
 	(Prompt2.__init__): Introduced new escape '\D' for continuation
 	prompts. It represents the counter ('\#') as dots.
 	*** NOTE *** THIS IS A BACKWARDS-INCOMPATIBLE CHANGE.  Users will
 	need to update their ipythonrc files and replace '%n' with '\D' in
 	their prompt_in2 settings everywhere.  Sorry, but there's
 	otherwise no clean way to get all prompts to properly align.  The
 	ipythonrc shipped with IPython has been updated.
 
 2004-06-07  Fernando Perez  <[e-mail]>
 
 	* setup.py (isfile): Pass local_icons option to latex2html, so the
 	resulting HTML file is self-contained.  Thanks to
 	dryice-AT-liu.com.cn for the tip.
 
 	* pysh.py: I created a new profile 'shell', which implements a
 	_rudimentary_ IPython-based shell.  This is in NO WAY a realy
 	system shell, nor will it become one anytime soon.  It's mainly
 	meant to illustrate the use of the new flexible bash-like prompts.
 	I guess it could be used by hardy souls for true shell management,
 	but it's no tcsh/bash...  pysh.py is loaded by the 'shell'
 	profile.  This uses the InterpreterExec extension provided by
 	W.J. van der Laan <gnufnork-AT-hetdigitalegat.nl>
 
 	* IPython/Prompts.py (PromptOut.__str__): now it will correctly
 	auto-align itself with the length of the previous input prompt
 	(taking into account the invisible color escapes).
 	(CachedOutput.__init__): Large restructuring of this class.  Now
 	all three prompts (primary1, primary2, output) are proper objects,
 	managed by the 'parent' CachedOutput class.  The code is still a
 	bit hackish (all prompts share state via a pointer to the cache),
 	but it's overall far cleaner than before.
 
 	* IPython/genutils.py (getoutputerror): modified to add verbose,
 	debug and header options.  This makes the interface of all getout*
 	functions uniform.
 	(SystemExec.getoutputerror): added getoutputerror to SystemExec.
 
 	* IPython/Magic.py (Magic.default_option): added a function to
 	allow registering default options for any magic command.  This
 	makes it easy to have profiles which customize the magics globally
 	for a certain use.  The values set through this function are
 	picked up by the parse_options() method, which all magics should
 	use to parse their options.
 
 	* IPython/genutils.py (warn): modified the warnings framework to
 	use the Term I/O class.  I'm trying to slowly unify all of
 	IPython's I/O operations to pass through Term.
 
 	* IPython/Prompts.py (Prompt2._str_other): Added functionality in
 	the secondary prompt to correctly match the length of the primary
 	one for any prompt.  Now multi-line code will properly line up
 	even for path dependent prompts, such as the new ones available
 	via the prompt_specials.
 
 2004-06-06  Fernando Perez  <[e-mail]>
 
 	* IPython/Prompts.py (prompt_specials): Added the ability to have
 	bash-like special sequences in the prompts, which get
 	automatically expanded.  Things like hostname, current working
 	directory and username are implemented already, but it's easy to
 	add more in the future.  Thanks to a patch by W.J. van der Laan
 	<gnufnork-AT-hetdigitalegat.nl>
 	(prompt_specials): Added color support for prompt strings, so
 	users can define arbitrary color setups for their prompts.
 
 2004-06-05  Fernando Perez  <[e-mail]>
 
 	* IPython/genutils.py (Term.reopen_all): Added Windows-specific
 	code to load Gary Bishop's readline and configure it
 	automatically.  Thanks to Gary for help on this.
 
 2004-06-01  Fernando Perez  <[e-mail]>
 
 	* IPython/Logger.py (Logger.create_log): fix bug for logging
 	with no filename (previous fix was incomplete).
 
 2004-05-25  Fernando Perez  <[e-mail]>
 
 	* IPython/Magic.py (Magic.parse_options): fix bug where naked
 	parens would get passed to the shell.
 
 2004-05-20  Fernando Perez  <[e-mail]>
 
 	* IPython/Magic.py (Magic.magic_prun): changed default profile
 	sort order to 'time' (the more common profiling need).
 
 	* IPython/OInspect.py (Inspector.pinfo): flush the inspect cache
 	so that source code shown is guaranteed in sync with the file on
 	disk (also changed in psource).  Similar fix to the one for
 	ultraTB on 2004-05-06.  Thanks to a bug report by Yann Le Du
 	<yann.ledu-AT-noos.fr>.
 	
 	* IPython/Magic.py (Magic.parse_options): Fixed bug where commands
 	with a single option would not be correctly parsed. Closes
 	http://www.scipy.net/roundup/ipython/issue14.  This bug had been
 	introduced in 0.6.0 (on 2004-05-06).
 
 2004-05-13  *** Released version 0.6.0
 
 2004-05-13  Fernando Perez  <[e-mail]>
 
 	* debian/: Added debian/ directory to CVS, so that debian support
 	is publicly accessible.  The debian package is maintained by Jack
 	Moffit <jack-AT-xiph.org>.
 
 	* Documentation: included the notes about an ipython-based system
 	shell (the hypothetical 'pysh') into the new_design.pdf document,
 	so that these ideas get distributed to users along with the
 	official documentation.
 
 2004-05-10  Fernando Perez  <[e-mail]>
 
 	* IPython/Logger.py (Logger.create_log): fix recently introduced
 	bug (misindented line) where logstart would fail when not given an
 	explicit filename.
 
 2004-05-09  Fernando Perez  <[e-mail]>
 
 	* IPython/Magic.py (Magic.parse_options): skip system call when
 	there are no options to look for.  Faster, cleaner for the common
 	case.
 
 	* Documentation: many updates to the manual: describing Windows
 	support better, Gnuplot updates, credits, misc small stuff.  Also
 	updated the new_design doc a bit.
 
 2004-05-06  *** Released version 0.6.0.rc1
 
 2004-05-06  Fernando Perez  <[e-mail]>
 
 	* IPython/ultraTB.py (ListTB.text): modified a ton of string +=
 	operations to use the vastly more efficient list/''.join() method.
 	(FormattedTB.text): Fix
 	http://www.scipy.net/roundup/ipython/issue12 - exception source
 	extract not updated after reload.  Thanks to Mike Salib
 	<msalib-AT-mit.edu> for pinning the source of the problem.
 	Fortunately, the solution works inside ipython and doesn't require
 	any changes to python proper.
 
 	* IPython/Magic.py (Magic.parse_options): Improved to process the
 	argument list as a true shell would (by actually using the
 	underlying system shell).  This way, all @magics automatically get
 	shell expansion for variables.  Thanks to a comment by Alex
 	Schmolck.
 
 2004-04-04  Fernando Perez  <[e-mail]>
 
 	* IPython/iplib.py (InteractiveShell.interact): Added a special
 	trap for a debugger quit exception, which is basically impossible
 	to handle by normal mechanisms, given what pdb does to the stack.
 	This fixes a crash reported by <fgibbons-AT-llama.med.harvard.edu>.
 
 2004-04-03  Fernando Perez  <[e-mail]>
 
 	* IPython/genutils.py (Term): Standardized the names of the Term
 	class streams to cin/cout/cerr, following C++ naming conventions
 	(I can't use in/out/err because 'in' is not a valid attribute
 	name).
 
 	* IPython/iplib.py (InteractiveShell.interact): don't increment
 	the prompt if there's no user input.  By Daniel 'Dang' Griffith
 	<pythondev-dang-AT-lazytwinacres.net>, after a suggestion from
 	Francois Pinard.
 
 2004-04-02  Fernando Perez  <[e-mail]>
 
 	* IPython/genutils.py (Stream.__init__): Modified to survive at
 	least importing in contexts where stdin/out/err aren't true file
 	objects, such as PyCrust (they lack fileno() and mode).  However,
 	the recovery facilities which rely on these things existing will
 	not work.
 
 2004-04-01  Fernando Perez  <[e-mail]>
 
 	* IPython/Magic.py (Magic.magic_sx): modified (as well as @sc) to
 	use the new getoutputerror() function, so it properly
 	distinguishes stdout/err.
 
 	* IPython/genutils.py (getoutputerror): added a function to
 	capture separately the standard output and error of a command.
 	After a comment from dang on the mailing lists.  This code is
 	basically a modified version of commands.getstatusoutput(), from
 	the standard library.
 
 	* IPython/iplib.py (InteractiveShell.handle_shell_escape): added
 	'!!' as a special syntax (shorthand) to access @sx.
 
 	* IPython/Magic.py (Magic.magic_sx): new magic, to execute a shell
 	command and return its output as a list split on '\n'.
 
 2004-03-31  Fernando Perez  <[e-mail]>
 
 	* IPython/FakeModule.py (FakeModule.__init__): added __nonzero__
 	method to dictionaries used as FakeModule instances if they lack
 	it.  At least pydoc in python2.3 breaks for runtime-defined
 	functions without this hack.  At some point I need to _really_
 	understand what FakeModule is doing, because it's a gross hack.
 	But it solves Arnd's problem for now...
 
 2004-02-27  Fernando Perez  <[e-mail]>
 
 	* IPython/Logger.py (Logger.create_log): Fix bug where 'rotate'
 	mode would behave erratically.  Also increased the number of
 	possible logs in rotate mod to 999.  Thanks to Rod Holland
 	<[e-mail]> for the report and fixes.

 	* IPython/genutils.py (page): Check that the curses module really
 	has the initscr attribute before trying to use it.  For some
 	reason, the Solaris curses module is missing this.  I think this
 	should be considered a Solaris python bug, but I'm not sure.
 
 2004-01-17  Fernando Perez  <[e-mail]>
 
 	* IPython/genutils.py (Stream.__init__): Changes to try to make
 	ipython robust against stdin/out/err being closed by the user.
 	This is 'user error' (and blocks a normal python session, at least
 	the stdout case).  However, Ipython should be able to survive such
 	instances of abuse as gracefully as possible.  To simplify the
 	coding and maintain compatibility with Gary Bishop's Term
 	contributions, I've made use of classmethods for this.  I think
 	this introduces a dependency on python 2.2.
 
 2004-01-13  Fernando Perez  <[e-mail]>
 
 	* IPython/numutils.py (exp_safe): simplified the code a bit and
 	removed the need for importing the kinds module altogether.
 
 2004-01-06  Fernando Perez  <[e-mail]>
 
 	* IPython/Magic.py (Magic.magic_sc): Made the shell capture system
 	a magic function instead, after some community feedback.  No
 	special syntax will exist for it, but its name is deliberately
 	very short.
 
 2003-12-20  Fernando Perez  <[e-mail]>
 
 	* IPython/iplib.py (InteractiveShell.handle_shell_assign): Added
 	new functionality, to automagically assign the result of a shell
 	command to a variable.  I'll solicit some community feedback on
 	this before making it permanent.
 
 	* IPython/OInspect.py (Inspector.pinfo): Fix crash when info was
 	requested about callables for which inspect couldn't obtain a
 	proper argspec.  Thanks to a crash report sent by Etienne
 	Posthumus <etienne-AT-apple01.cs.vu.nl>.
 
 2003-12-09  Fernando Perez  <[e-mail]>
 
 	* IPython/genutils.py (page): patch for the pager to work across
 	various versions of Windows.  By Gary Bishop.
 
 2003-12-04  Fernando Perez  <[e-mail]>
 
 	* IPython/Gnuplot2.py (PlotItems): Fixes for working with
 	Gnuplot.py version 1.7, whose internal names changed quite a bit.
 	While I tested this and it looks ok, there may still be corner
 	cases I've missed.
 
 2003-12-01  Fernando Perez  <[e-mail]>
 
 	* IPython/iplib.py (InteractiveShell._prefilter): Fixed a bug
 	where a line like 'p,q=1,2' would fail because the automagic
 	system would be triggered for @p.
 
 	* IPython/DPyGetOpt.py (DPyGetOpt.processArguments): Tab-related
 	cleanups, code unmodified.
 
 	* IPython/genutils.py (Term): added a class for IPython to handle
 	output.  In most cases it will just be a proxy for stdout/err, but
 	having this allows modifications to be made for some platforms,
 	such as handling color escapes under Windows.  All of this code
 	was contributed by Gary Bishop, with minor modifications by me.
 	The actual changes affect many files.
 
 2003-11-30  Fernando Perez  <[e-mail]>
 
 	* IPython/iplib.py (file_matches): new completion code, courtesy
 	of Jeff Collins.  This enables filename completion again under
 	python 2.3, which disabled it at the C level.
 
 2003-11-11  Fernando Perez  <[e-mail]>
 
 	* IPython/numutils.py (amap): Added amap() fn.  Simple shorthand
 	for Numeric.array(map(...)), but often convenient.
 
 2003-11-05  Fernando Perez  <[e-mail]>
 
 	* IPython/numutils.py (frange): Changed a call from int() to
 	int(round()) to prevent a problem reported with arange() in the
 	numpy list.
 
 2003-10-06  Fernando Perez  <[e-mail]>
 
 	* IPython/DPyGetOpt.py (DPyGetOpt.processArguments): changed to
 	prevent crashes if sys lacks an argv attribute (it happens with
 	embedded interpreters which build a bare-bones sys module).
 	Thanks to a report/bugfix by Adam Hupp <hupp-AT-cs.wisc.edu>.
 
 2003-09-24  Fernando Perez  <[e-mail]>
 
 	* IPython/Magic.py (Magic._ofind): blanket except around getattr()
 	to protect against poorly written user objects where __getattr__
 	raises exceptions other than AttributeError.  Thanks to a bug
 	report by Oliver Sander <osander-AT-gmx.de>.
 
 	* IPython/FakeModule.py (FakeModule.__repr__): this method was
 	missing.  Thanks to bug report by Ralf Schmitt <ralf-AT-brainbot.com>.
 
 2003-09-09  Fernando Perez  <[e-mail]>
 
 	* IPython/iplib.py (InteractiveShell._prefilter): fix bug where
 	unpacking a list whith a callable as first element would
 	mistakenly trigger autocalling.  Thanks to a bug report by Jeffery
 	Collins.
 
 2003-08-25  *** Released version 0.5.0
 
 2003-08-22  Fernando Perez  <[e-mail]>
 
 	* IPython/ultraTB.py (VerboseTB.linereader): Improved handling of
 	improperly defined user exceptions.  Thanks to feedback from Mark
 	Russell <mrussell-AT-verio.net>.
 	
 2003-08-20  Fernando Perez  <[e-mail]>
 
 	* IPython/OInspect.py (Inspector.pinfo): changed String Form
 	printing so that it would print multi-line string forms starting
 	with a new line.  This way the formatting is better respected for
 	objects which work hard to make nice string forms.
 
 	* IPython/iplib.py (InteractiveShell.handle_auto): Fix bug where
 	autocall would overtake data access for objects with both
 	__getitem__ and __call__.
 
 2003-08-19  *** Released version 0.5.0-rc1
 
 2003-08-19  Fernando Perez  <[e-mail]>
 
 	* IPython/deep_reload.py (load_tail): single tiny change here
 	seems to fix the long-standing bug of dreload() failing to work
 	for dotted names.  But this module is pretty tricky, so I may have
 	missed some subtlety.  Needs more testing!.
 
 	* IPython/ultraTB.py (VerboseTB.linereader): harden against user
 	exceptions which have badly implemented __str__ methods.
 	(VerboseTB.text): harden against inspect.getinnerframes crashing,
 	which I've been getting reports about from Python 2.3 users.  I
 	wish I had a simple test case to reproduce the problem, so I could
 	either write a cleaner workaround or file a bug report if
 	necessary.
 
 	* IPython/Magic.py (Magic.magic_edit): fixed bug where after
 	making a class 'foo', file 'foo.py' couldn't be edited.  Thanks to
 	a bug report by Tjabo Kloppenburg.
 
 	* IPython/ultraTB.py (VerboseTB.debugger): hardened against pdb
 	crashes.  Wrapped the pdb call in a blanket try/except, since pdb
 	seems rather unstable.  Thanks to a bug report by Tjabo
 	Kloppenburg <tjabo.kloppenburg-AT-unix-ag.uni-siegen.de>.
 
 	* IPython/Release.py (version): release 0.5.0-rc1.  I want to put
 	this out soon because of the critical fixes in the inner loop for
 	generators.
 
 	* IPython/Magic.py (Magic.getargspec): removed.  This (and
 	_get_def) have been obsoleted by OInspect for a long time, I
 	hadn't noticed that they were dead code.
 	(Magic._ofind): restored _ofind functionality for a few literals
 	(those in ["''",'""','[]','{}','()']).  But it won't work anymore
 	for things like "hello".capitalize?, since that would require a
 	potentially dangerous eval() again.
 
 	* IPython/iplib.py (InteractiveShell._prefilter): reorganized the
 	logic a bit more to clean up the escapes handling and minimize the
 	use of _ofind to only necessary cases.  The interactive 'feel' of
 	IPython should have improved quite a bit with the changes in
 	_prefilter and _ofind (besides being far safer than before).
 
 	* IPython/Magic.py (Magic.magic_edit): Fixed old bug (but rather
 	obscure, never reported).  Edit would fail to find the object to
 	edit under some circumstances.
 	(Magic._ofind): CRITICAL FIX.  Finally removed the eval() calls
 	which were causing double-calling of generators.  Those eval calls
 	were _very_ dangerous, since code with side effects could be
 	triggered.  As they say, 'eval is evil'...  These were the
 	nastiest evals in IPython.  Besides, _ofind is now far simpler,
 	and it should also be quite a bit faster.  Its use of inspect is
 	also safer, so perhaps some of the inspect-related crashes I've
 	seen lately with Python 2.3 might be taken care of.  That will
 	need more testing.
 
 2003-08-17  Fernando Perez  <[e-mail]>
 
 	* IPython/iplib.py (InteractiveShell._prefilter): significant
 	simplifications to the logic for handling user escapes.  Faster
 	and simpler code.
 
 2003-08-14  Fernando Perez  <[e-mail]>
 
         * IPython/numutils.py (sum_flat): rewrote to be non-recursive.
         Now it requires O(N) storage (N=size(a)) for non-contiguous input,
         but it should be quite a bit faster.  And the recursive version
         generated O(log N) intermediate storage for all rank>1 arrays,
         even if they were contiguous.
         (l1norm): Added this function.
         (norm):  Added this function for arbitrary norms (including
         l-infinity).  l1 and l2 are still special cases for convenience
         and speed.
 	
 2003-08-03  Fernando Perez  <[e-mail]>
 
 	* IPython/Magic.py (Magic.magic_edit): Removed all remaining string
 	exceptions, which now raise PendingDeprecationWarnings in Python
 	2.3.  There were some in Magic and some in Gnuplot2.
 
 2003-06-30  Fernando Perez  <[e-mail]>
 
 	* IPython/genutils.py (page): modified to call curses only for
 	terminals where TERM=='xterm'.  After problems under many other
 	terminals were reported by Keith Beattie <KSBeattie-AT-lbl.gov>.
 
 	* IPython/iplib.py (complete): removed spurious 'print "IE"' which
 	would be triggered when readline was absent.  This was just an old
 	debugging statement I'd forgotten to take out.
 
 2003-06-20  Fernando Perez  <[e-mail]>
 
 	* IPython/genutils.py (clock): modified to return only user time
 	(not counting system time), after a discussion on scipy.  While
 	system time may be a useful quantity occasionally, it may much
 	more easily be skewed by occasional swapping or other similar
 	activity.
 
 2003-06-05  Fernando Perez  <[e-mail]>
 
 	* IPython/numutils.py (identity): new function, for building
 	arbitrary rank Kronecker deltas (mostly backwards compatible with
 	Numeric.identity)
 
 2003-06-03  Fernando Perez  <[e-mail]>
 
 	* IPython/iplib.py (InteractiveShell.handle_magic): protect
 	arguments passed to magics with spaces, to allow trailing '\' to
 	work normally (mainly for Windows users).
 
 2003-05-29  Fernando Perez  <[e-mail]>
 
 	* IPython/ipmaker.py (make_IPython): Load site._Helper() as help
 	instead of pydoc.help.  This fixes a bizarre behavior where
 	printing '%s' % locals() would trigger the help system.  Now
 	ipython behaves like normal python does.  
 
 	Note that if one does 'from pydoc import help', the bizarre
 	behavior returns, but this will also happen in normal python, so
 	it's not an ipython bug anymore (it has to do with how pydoc.help
 	is implemented).
 
 2003-05-22  Fernando Perez  <[e-mail]>
 
 	* IPython/FlexCompleter.py (Completer.attr_matches): fixed to
 	return [] instead of None when nothing matches, also match to end
 	of line.  Patch by Gary Bishop.
 
 	* IPython/ipmaker.py (make_IPython): Added same sys.excepthook
 	protection as before, for files passed on the command line.  This
 	prevents the CrashHandler from kicking in if user files call into
 	sys.excepthook (such as PyQt and WxWindows have a nasty habit of
 	doing).  After a report by Kasper Souren <Kasper.Souren-AT-ircam.fr>
 
 2003-05-20  *** Released version 0.4.0
 
 2003-05-20  Fernando Perez  <[e-mail]>
 
 	* setup.py: added support for manpages.  It's a bit hackish b/c of
 	a bug in the way the bdist_rpm distutils target handles gzipped
 	manpages, but it works.  After a patch by Jack.
 
 2003-05-19  Fernando Perez  <[e-mail]>
 
 	* IPython/numutils.py: added a mockup of the kinds module, since
 	it was recently removed from Numeric.  This way, numutils will
 	work for all users even if they are missing kinds.
 
 	* IPython/Magic.py (Magic._ofind): Harden against an inspect
 	failure, which can occur with SWIG-wrapped extensions.  After a
 	crash report from Prabhu.
 
 2003-05-16  Fernando Perez  <[e-mail]>
 
 	* IPython/iplib.py (InteractiveShell.excepthook): New method to
 	protect ipython from user code which may call directly
 	sys.excepthook (this looks like an ipython crash to the user, even
 	when it isn't).  After a patch by Gary Bishop <gb-AT-cs.unc.edu>.
 	This is especially important to help users of WxWindows, but may
 	also be useful in other cases.
 
 	* IPython/ultraTB.py (AutoFormattedTB.__call__): Changed to allow
 	an optional tb_offset to be specified, and to preserve exception
 	info if given.  After a patch by Gary Bishop <gb-AT-cs.unc.edu>.
 
 	* ipython.1 (Default): Thanks to Jack's work, we now have manpages!
 
 2003-05-15  Fernando Perez  <[e-mail]>
 
 	* IPython/iplib.py (InteractiveShell.user_setup): Fix crash when
 	installing for a new user under Windows.
 
 2003-05-12  Fernando Perez  <[e-mail]>
 
 	* IPython/iplib.py (InteractiveShell.handle_emacs): New line
 	handler for Emacs comint-based lines.  Currently it doesn't do
 	much (but importantly, it doesn't update the history cache).  In
 	the future it may be expanded if Alex needs more functionality
 	there.
 
 	* IPython/CrashHandler.py (CrashHandler.__call__): Added platform
 	info to crash reports.
 
 	* IPython/iplib.py (InteractiveShell.mainloop): Added -c option,
 	just like Python's -c.  Also fixed crash with invalid -color
 	option value at startup. Thanks to Will French
 	<wfrench-AT-bestweb.net> for the bug report.
 
 2003-05-09  Fernando Perez  <[e-mail]>
 
 	* IPython/genutils.py (EvalDict.__getitem__): Renamed EvalString
 	to EvalDict (it's a mapping, after all) and simplified its code
 	quite a bit, after a nice discussion on c.l.py where Gustavo
 	Córdova <gcordova-AT-sismex.com> suggested the new version.
 
 2003-04-30  Fernando Perez  <[e-mail]>
 
 	* IPython/genutils.py (timings_out): modified it to reduce its
 	overhead in the common reps==1 case.
 
 2003-04-29  Fernando Perez  <[e-mail]>
 
 	* IPython/genutils.py (timings_out): Modified to use the resource
 	module, which avoids the wraparound problems of time.clock().
 
 2003-04-17  *** Released version 0.2.15pre4
 
 2003-04-17  Fernando Perez  <[e-mail]>
 
 	* setup.py (scriptfiles): Split windows-specific stuff over to a
 	separate file, in an attempt to have a Windows GUI installer.
 	That didn't work, but part of the groundwork is done.
 
 	* IPython/UserConfig/ipythonrc: Added M-i, M-o and M-I for
 	indent/unindent with 4 spaces.  Particularly useful in combination
 	with the new auto-indent option.
 
 2003-04-16  Fernando Perez  <[e-mail]>
 
 	* IPython/Magic.py: various replacements of self.rc for
 	self.shell.rc.  A lot more remains to be done to fully disentangle
 	this class from the main Shell class.
 
 	* IPython/GnuplotRuntime.py: added checks for mouse support so
 	that we don't try to enable it if the current gnuplot doesn't
 	really support it.  Also added checks so that we don't try to
 	enable persist under Windows (where Gnuplot doesn't recognize the
 	option).
 
 	* IPython/iplib.py (InteractiveShell.interact): Added optional
 	auto-indenting code, after a patch by King C. Shu
 	<kingshu-AT-myrealbox.com>. It's off by default because it doesn't
 	get along well with pasting indented code.  If I ever figure out
 	how to make that part go well, it will become on by default.
 
 	* IPython/Prompts.py (Prompt1.auto_rewrite): Fixed bug which would
 	crash ipython if there was an unmatched '%' in the user's prompt
 	string.  Reported by Thorsten Kampe <thorsten-AT-thorstenkampe.de>.
 	
 	* IPython/iplib.py (InteractiveShell.interact): removed the
 	ability to ask the user whether he wants to crash or not at the
 	'last line' exception handler.  Calling functions at that point
 	changes the stack, and the error reports would have incorrect
 	tracebacks.
 
 	* IPython/Magic.py (Magic.magic_page): Added new @page magic, to
 	pass through a peger a pretty-printed form of any object.  After a
 	contribution by Olivier Aubert <oaubert-AT-bat710.univ-lyon1.fr>
 
 2003-04-14  Fernando Perez  <[e-mail]>
 
 	* IPython/iplib.py (InteractiveShell.user_setup): Fixed bug where
 	all files in ~ would be modified at first install (instead of
 	~/.ipython).  This could be potentially disastrous, as the
 	modification (make line-endings native) could damage binary files.
 	
 2003-04-10  Fernando Perez  <[e-mail]>
 
 	* IPython/iplib.py (InteractiveShell.handle_help): Modified to
 	handle only lines which are invalid python.  This now means that
 	lines like 'x=1 #?' execute properly.  Thanks to Jeffery Collins
 	for the bug report.
 
 2003-04-01  Fernando Perez  <[e-mail]>
 
 	* IPython/iplib.py (InteractiveShell.showtraceback): Fixed bug
 	where failing to set sys.last_traceback would crash pdb.pm().
 	Thanks to Jeffery D. Collins <Jeff.Collins-AT-vexcel.com> for the bug
 	report.
 
 2003-03-25  Fernando Perez  <[e-mail]>
 
 	* IPython/Magic.py (Magic.magic_prun): rstrip() output of profiler
 	before printing it (it had a lot of spurious blank lines at the
 	end).
 
 	* IPython/Gnuplot2.py (Gnuplot.hardcopy): fixed bug where lpr
 	output would be sent 21 times!  Obviously people don't use this
 	too often, or I would have heard about it.
 
 2003-03-24  Fernando Perez  <[e-mail]>
 
 	* setup.py (scriptfiles): renamed the data_files parameter from
 	'base' to 'data' to fix rpm build issues.  Thanks to Ralf Ahlbrink
 	for the patch.
 
 2003-03-20  Fernando Perez  <[e-mail]>
 
 	* IPython/genutils.py (error): added error() and fatal()
 	functions.
 
 2003-03-18  *** Released version 0.2.15pre3
 
 2003-03-18  Fernando Perez  <[e-mail]>
 
 	* setupext/install_data_ext.py
 	(install_data_ext.initialize_options): Class contributed by Jack
 	Moffit for fixing the old distutils hack.  He is sending this to
 	the distutils folks so in the future we may not need it as a
 	private fix.
 
 	* MANIFEST.in: Extensive reorganization, based on Jack Moffit's
 	changes for Debian packaging.  See his patch for full details.
 	The old distutils hack of making the ipythonrc* files carry a
 	bogus .py extension is gone, at last.  Examples were moved to a
 	separate subdir under doc/, and the separate executable scripts
 	now live in their own directory.  Overall a great cleanup.  The
 	manual was updated to use the new files, and setup.py has been
 	fixed for this setup.
 
 	* IPython/PyColorize.py (Parser.usage): made non-executable and
 	created a pycolor wrapper around it to be included as a script.
 
 2003-03-12  *** Released version 0.2.15pre2
 
 2003-03-12  Fernando Perez  <[e-mail]>
 
 	* IPython/ColorANSI.py (make_color_table): Finally fixed the
 	long-standing problem with garbage characters in some terminals.
 	The issue was really that the \001 and \002 escapes must _only_ be
 	passed to input prompts (which call readline), but _never_ to
 	normal text to be printed on screen.  I changed ColorANSI to have
 	two classes: TermColors and InputTermColors, each with the
 	appropriate escapes for input prompts or normal text.  The code in
 	Prompts.py got slightly more complicated, but this very old and
 	annoying bug is finally fixed.  
 
 	All the credit for nailing down the real origin of this problem
 	and the correct solution goes to Jack Moffit <jack-AT-xiph.org>.
 	*Many* thanks to him for spending quite a bit of effort on this.
 
 2003-03-05  *** Released version 0.2.15pre1
 
 2003-03-03  Fernando Perez  <[e-mail]>
 
 	* IPython/FakeModule.py: Moved the former _FakeModule to a
 	separate file, because it's also needed by Magic (to fix a similar
 	pickle-related issue in @run).
 
 2003-03-02  Fernando Perez  <[e-mail]>
 
 	* IPython/Magic.py (Magic.magic_autocall): new magic to control
 	the autocall option at runtime.
 	(Magic.magic_dhist): changed self.user_ns to self.shell.user_ns
 	across Magic.py to start separating Magic from InteractiveShell.
 	(Magic._ofind): Fixed to return proper namespace for dotted
 	names. Before, a dotted name would always return 'not currently
 	defined', because it would find the 'parent'. s.x would be found,
 	but since 'x' isn't defined by itself, it would get confused.
 	(Magic.magic_run): Fixed pickling problems reported by Ralf
 	Ahlbrink <RAhlbrink-AT-RosenInspection.net>.  The fix was similar to
 	that I'd used when Mike Heeter reported similar issues at the
 	top-level, but now for @run.  It boils down to injecting the
 	namespace where code is being executed with something that looks
 	enough like a module to fool pickle.dump().  Since a pickle stores
 	a named reference to the importing module, we need this for
 	pickles to save something sensible.
 
 	* IPython/ipmaker.py (make_IPython): added an autocall option.
 
 	* IPython/iplib.py (InteractiveShell._prefilter): reordered all of
 	the auto-eval code.  Now autocalling is an option, and the code is
 	also vastly safer.  There is no more eval() involved at all.
 
 2003-03-01  Fernando Perez  <[e-mail]>
 
 	* IPython/Magic.py (Magic._ofind): Changed interface to return a
 	dict with named keys instead of a tuple.
 
 	* IPython: Started using CVS for IPython as of 0.2.15pre1.
 
 	* setup.py (make_shortcut): Fixed message about directories
 	created during Windows installation (the directories were ok, just
 	the printed message was misleading).  Thanks to Chris Liechti
 	<cliechti-AT-gmx.net> for the heads up.
 
 2003-02-21  Fernando Perez  <[e-mail]>
 
 	* IPython/iplib.py (InteractiveShell._prefilter): Fixed catching
 	of ValueError exception when checking for auto-execution.  This
 	one is raised by things like Numeric arrays arr.flat when the
 	array is non-contiguous.
 
 2003-01-31  Fernando Perez  <[e-mail]>
 
 	* IPython/genutils.py (SystemExec.bq): Fixed bug where bq would
 	not return any value at all (even though the command would get
 	executed).
 	(xsys): Flush stdout right after printing the command to ensure
 	proper ordering of commands and command output in the total
 	output.
 	(SystemExec/xsys/bq): Switched the names of xsys/bq and
 	system/getoutput as defaults.  The old ones are kept for
 	compatibility reasons, so no code which uses this library needs
 	changing.
 
 2003-01-27  *** Released version 0.2.14
 
 2003-01-25  Fernando Perez  <[e-mail]>
 
 	* IPython/Magic.py (Magic.magic_edit): Fixed problem where
 	functions defined in previous edit sessions could not be re-edited
 	(because the temp files were immediately removed).  Now temp files
 	are removed only at IPython's exit.
 	(Magic.magic_run): Improved @run to perform shell-like expansions
 	on its arguments (~users and $VARS).  With this, @run becomes more
 	like a normal command-line.
 
 	* IPython/Shell.py (IPShellEmbed.__call__): Fixed a bunch of small
 	bugs related to embedding and cleaned up that code.  A fairly
 	important one was the impossibility to access the global namespace
 	through the embedded IPython (only local variables were visible).
 
 2003-01-14  Fernando Perez  <[e-mail]>
 
 	* IPython/iplib.py (InteractiveShell._prefilter): Fixed
 	auto-calling to be a bit more conservative.  Now it doesn't get
 	triggered if any of '!=()<>' are in the rest of the input line, to
 	allow comparing callables.  Thanks to Alex for the heads up.
 
 2003-01-07  Fernando Perez  <[e-mail]>
 
 	* IPython/genutils.py (page): fixed estimation of the number of
 	lines in a string to be paged to simply count newlines. This
 	prevents over-guessing due to embedded escape sequences. A better
 	long-term solution would involve stripping out the control chars
 	for the count, but it's potentially so expensive I just don't
 	think it's worth doing.
 
 2002-12-19  *** Released version 0.2.14pre50
 
 2002-12-19  Fernando Perez  <[e-mail]>
 
 	* tools/release (version): Changed release scripts to inform
 	Andrea and build a NEWS file with a list of recent changes.
 
 	* IPython/ColorANSI.py (__all__): changed terminal detection
 	code. Seems to work better for xterms without breaking
 	konsole. Will need more testing to determine if WinXP and Mac OSX
 	also work ok.
 
 2002-12-18  *** Released version 0.2.14pre49
 
 2002-12-18  Fernando Perez  <[e-mail]>
 
 	* Docs: added new info about Mac OSX, from Andrea.
 
 	* IPython/Gnuplot2.py (String): Added a String PlotItem class to
 	allow direct plotting of python strings whose format is the same
 	of gnuplot data files.
 
 2002-12-16  Fernando Perez  <[e-mail]>
 
 	* IPython/iplib.py (InteractiveShell.interact): fixed default (y)
 	value of exit question to be acknowledged.
 
 2002-12-03  Fernando Perez  <[e-mail]>
 
 	* IPython/ipmaker.py: removed generators, which had been added
 	by mistake in an earlier debugging run. This was causing trouble
 	to users of python 2.1.x. Thanks to Abel Daniel <abli-AT-freemail.hu>
 	for pointing this out.
 
 2002-11-17  Fernando Perez  <[e-mail]>
 
 	* Manual: updated the Gnuplot section.
 
 	* IPython/GnuplotRuntime.py: refactored a lot all this code, with
 	a much better split of what goes in Runtime and what goes in
 	Interactive.
 
 	* IPython/ipmaker.py: fixed bug where import_fail_info wasn't
 	being imported from iplib.
 
 	* IPython/GnuplotInteractive.py (magic_gpc): renamed @gp to @gpc
 	for command-passing. Now the global Gnuplot instance is called
 	'gp' instead of 'g', which was really a far too fragile and
 	common name.
 
 	* IPython/Gnuplot2.py (eps_fix_bbox): added this to fix broken
 	bounding boxes generated by Gnuplot for square plots.
 
 	* IPython/genutils.py (popkey): new function added. I should
 	suggest this on c.l.py as a dict method, it seems useful.
 
 	* IPython/Gnuplot2.py (Gnuplot.plot): Overhauled plot and replot
 	to transparently handle PostScript generation. MUCH better than
 	the previous plot_eps/replot_eps (which I removed now). The code
 	is also fairly clean and well documented now (including
 	docstrings).
 
 2002-11-13  Fernando Perez  <[e-mail]>
 
 	* IPython/Magic.py (Magic.magic_edit): fixed docstring
 	(inconsistent with options).
 
 	* IPython/Gnuplot2.py (Gnuplot.hardcopy): hardcopy had been
 	manually disabled, I don't know why. Fixed it.
 	(Gnuplot._plot_eps): added new plot_eps/replot_eps to get directly
 	eps output.
 
 2002-11-12  Fernando Perez  <[e-mail]>
 
 	* IPython/genutils.py (ask_yes_no): trap EOF and ^C so that they
 	don't propagate up to caller. Fixes crash reported by François
 	Pinard.
 
 2002-11-09  Fernando Perez  <[e-mail]>
 
 	* IPython/ipmaker.py (make_IPython): fixed problem with writing
 	history file for new users.
 	(make_IPython): fixed bug where initial install would leave the
 	user running in the .ipython dir.
 	(make_IPython): fixed bug where config dir .ipython would be
 	created regardless of the given -ipythondir option. Thanks to Cory
 	Dodt <cdodt-AT-fcoe.k12.ca.us> for the bug report.
 
 	* IPython/genutils.py (ask_yes_no): new function for asking yes/no
 	type confirmations. Will need to use it in all of IPython's code
 	consistently.
 	
 	* IPython/CrashHandler.py (CrashHandler.__call__): changed the
 	context to print 31 lines instead of the default 5. This will make
 	the crash reports extremely detailed in case the problem is in
 	libraries I don't have access to.
 
 	* IPython/iplib.py (InteractiveShell.interact): changed the 'last
 	line of defense' code to still crash, but giving users fair
 	warning. I don't want internal errors to go unreported: if there's
 	an internal problem, IPython should crash and generate a full
 	report.
 
 2002-11-08  Fernando Perez  <[e-mail]>
 
 	* IPython/iplib.py (InteractiveShell.interact): added code to trap
 	otherwise uncaught exceptions which can appear if people set
 	sys.stdout to something badly broken. Thanks to a crash report
 	from henni-AT-mail.brainbot.com.
 
 2002-11-04  Fernando Perez  <[e-mail]>
 
 	* IPython/iplib.py (InteractiveShell.interact): added
 	__IPYTHON__active to the builtins. It's a flag which goes on when
 	the interaction starts and goes off again when it stops. This
 	allows embedding code to detect being inside IPython. Before this
 	was done via __IPYTHON__, but that only shows that an IPython
 	instance has been created.
 
 	* IPython/Magic.py (Magic.magic_env): I realized that in a
 	UserDict, instance.data holds the data as a normal dict. So I
 	modified @env to return os.environ.data instead of rebuilding a
 	dict by hand.
 
 2002-11-02  Fernando Perez  <[e-mail]>
 
 	* IPython/genutils.py (warn): changed so that level 1 prints no
 	header. Level 2 is now the default (with 'WARNING' header, as
 	before). I think I tracked all places where changes were needed in
 	IPython, but outside code using the old level numbering may have
 	broken.
 
 	* IPython/iplib.py (InteractiveShell.runcode): added this to
 	handle the tracebacks in SystemExit traps correctly. The previous
 	code (through interact) was printing more of the stack than
 	necessary, showing IPython internal code to the user.
 
 	* IPython/UserConfig/ipythonrc.py: Made confirm_exit 1 by
 	default. Now that the default at the confirmation prompt is yes,
 	it's not so intrusive. François' argument that ipython sessions
 	tend to be complex enough not to lose them from an accidental C-d,
 	is a valid one.
 
 	* IPython/iplib.py (InteractiveShell.interact): added a
 	showtraceback() call to the SystemExit trap, and modified the exit
 	confirmation to have yes as the default.
 
 	* IPython/UserConfig/ipythonrc.py: removed 'session' option from
 	this file. It's been gone from the code for a long time, this was
 	simply leftover junk.
 
 2002-11-01  Fernando Perez  <[e-mail]>
 
 	* IPython/UserConfig/ipythonrc.py: new confirm_exit option
 	added. If set, IPython now traps EOF and asks for
 	confirmation. After a request by François Pinard.
 
 	* IPython/Magic.py (Magic.magic_Exit): New @Exit and @Quit instead
 	of @abort, and with a new (better) mechanism for handling the
 	exceptions.
 
 2002-10-27  Fernando Perez  <[e-mail]>
 
 	* IPython/usage.py (__doc__): updated the --help information and
 	the ipythonrc file to indicate that -log generates
 	./ipython.log. Also fixed the corresponding info in @logstart.
 	This and several other fixes in the manuals thanks to reports by
 	François Pinard <pinard-AT-iro.umontreal.ca>.
 	
 	* IPython/Logger.py (Logger.switch_log): Fixed error message to
 	refer to @logstart (instead of @log, which doesn't exist).
 
 	* IPython/iplib.py (InteractiveShell._prefilter): fixed
 	AttributeError crash. Thanks to Christopher Armstrong
 	<radix-AT-twistedmatrix.com> for the report/fix. This bug had been
 	introduced recently (in 0.2.14pre37) with the fix to the eval
 	problem mentioned below.
 	
 2002-10-17  Fernando Perez  <[e-mail]>
 
 	* IPython/ConfigLoader.py (ConfigLoader.load): Fixes for Windows
 	installation. Thanks to Leonardo Santagada <retype-AT-terra.com.br>.
 
 	* IPython/iplib.py (InteractiveShell._prefilter): Many changes to
 	this function to fix a problem reported by Alex Schmolck. He saw
 	it with list comprehensions and generators, which were getting
 	called twice. The real problem was an 'eval' call in testing for
 	automagic which was evaluating the input line silently. 
 
 	This is a potentially very nasty bug, if the input has side
 	effects which must not be repeated. The code is much cleaner now,
 	without any blanket 'except' left and with a regexp test for
 	actual function names. 
 
 	But an eval remains, which I'm not fully comfortable with. I just
 	don't know how to find out if an expression could be a callable in
 	the user's namespace without doing an eval on the string. However
 	that string is now much more strictly checked so that no code
 	slips by, so the eval should only happen for things that can
 	really be only function/method names.
 
 2002-10-15  Fernando Perez  <[e-mail]>
 
 	* Updated LyX to 1.2.1 so I can work on the docs again. Added Mac
 	OSX information to main manual, removed README_Mac_OSX file from
 	distribution. Also updated credits for recent additions.
 
 2002-10-10  Fernando Perez  <[e-mail]>
 
 	* README_Mac_OSX: Added a README for Mac OSX users for fixing
 	terminal-related issues. Many thanks to Andrea Riciputi
 	<andrea.riciputi-AT-libero.it> for writing it.
 
 	* IPython/UserConfig/ipythonrc.py: Fixes to various small issues,
 	thanks to Thorsten Kampe <thorsten-AT-thorstenkampe.de>.
 
 	* setup.py (make_shortcut): Fixes for Windows installation. Thanks
 	to Fredrik Kant <fredrik.kant-AT-front.com> and Syver Enstad
 	<syver-en-AT-online.no> who both submitted patches for this problem.
 
 	* IPython/iplib.py (InteractiveShell.embed_mainloop): Patch for
 	global embedding to make sure that things don't overwrite user
 	globals accidentally. Thanks to Richard <rxe-AT-renre-europe.com>
 
 	* IPython/Gnuplot2.py (gp): Patch for Gnuplot.py 1.6
 	compatibility. Thanks to Hayden Callow
 	<h.callow-AT-elec.canterbury.ac.nz>
 
 2002-10-04  Fernando Perez  <[e-mail]>
 
 	* IPython/Gnuplot2.py (PlotItem): Added 'index' option for
 	Gnuplot.File objects.
 	      
 2002-07-23  Fernando Perez  <[e-mail]>
 
 	* IPython/genutils.py (timing): Added timings() and timing() for
 	quick access to the most commonly needed data, the execution
 	times. Old timing() renamed to timings_out().
 
 2002-07-18  Fernando Perez  <[e-mail]>
 
 	* IPython/Shell.py (IPShellEmbed.restore_system_completer): fixed
 	bug with nested instances disrupting the parent's tab completion.
 
 	* IPython/iplib.py (all_completions): Added Alex Schmolck's
 	all_completions code to begin the emacs integration.
 
 	* IPython/Gnuplot2.py (zip_items): Added optional 'titles'
 	argument to allow titling individual arrays when plotting.
 
 2002-07-15  Fernando Perez  <[e-mail]>
 
 	* setup.py (make_shortcut): changed to retrieve the value of
 	'Program Files' directory from the registry (this value changes in
 	non-english versions of Windows). Thanks to Thomas Fanslau
 	<tfanslau-AT-gmx.de> for the report.
 
 2002-07-10  Fernando Perez  <[e-mail]>
 
 	* IPython/ultraTB.py (VerboseTB.debugger): enabled workaround for
 	a bug in pdb, which crashes if a line with only whitespace is
 	entered. Bug report submitted to sourceforge.
 
 2002-07-09  Fernando Perez  <[e-mail]>
 
 	* IPython/ultraTB.py (VerboseTB.nullrepr): fixed rare crash when
 	reporting exceptions (it's a bug in inspect.py, I just set a
 	workaround).
 
 2002-07-08  Fernando Perez  <[e-mail]>
 
 	* IPython/iplib.py (InteractiveShell.__init__): fixed reference to
 	__IPYTHON__ in __builtins__ to show up in user_ns.
 
 2002-07-03  Fernando Perez  <[e-mail]>
 
 	* IPython/GnuplotInteractive.py (magic_gp_set_default): changed
 	name from @gp_set_instance to @gp_set_default.
 
 	* IPython/ipmaker.py (make_IPython): default editor value set to
 	'0' (a string), to match the rc file. Otherwise will crash when
 	.strip() is called on it.
 	
 
 2002-06-28  Fernando Perez  <[e-mail]>
 
 	* IPython/iplib.py (InteractiveShell.safe_execfile): fix importing
 	of files in current directory when a file is executed via
 	@run. Patch also by RA <ralf_ahlbrink-AT-web.de>.
 
 	* setup.py (manfiles): fix for rpm builds, submitted by RA
 	<ralf_ahlbrink-AT-web.de>. Now we have RPMs!
 
 	* IPython/ipmaker.py (make_IPython): fixed lookup of default
 	editor when set to '0'. Problem was, '0' evaluates to True (it's a
 	string!). A. Schmolck caught this one.
 
 2002-06-27  Fernando Perez  <[e-mail]>
 
 	* IPython/ipmaker.py (make_IPython): fixed bug when running user
 	defined files at the cmd line. __name__ wasn't being set to
 	__main__.
 
 	* IPython/Gnuplot2.py (zip_items): improved it so it can plot also
 	regular lists and tuples besides Numeric arrays.
 
 	* IPython/Prompts.py (CachedOutput.__call__): Added output
 	supression for input ending with ';'. Similar to Mathematica and
 	Matlab. The _* vars and Out[] list are still updated, just like
 	Mathematica behaves.
 
 2002-06-25  Fernando Perez  <[e-mail]>
 
 	* IPython/ConfigLoader.py (ConfigLoader.load): fixed checking of
 	.ini extensions for profiels under Windows.
 
 	* IPython/OInspect.py (Inspector.pinfo): improved alignment of
 	string form. Fix contributed by Alexander Schmolck
 	<a.schmolck-AT-gmx.net>
 
 	* IPython/GnuplotRuntime.py (gp_new): new function. Returns a
 	pre-configured Gnuplot instance.
 
 2002-06-21  Fernando Perez  <[e-mail]>
 
 	* IPython/numutils.py (exp_safe): new function, works around the
 	underflow problems in Numeric.
 	(log2): New fn. Safe log in base 2: returns exact integer answer
 	for exact integer powers of 2.
 
 	* IPython/Magic.py (get_py_filename): fixed it not expanding '~'
 	properly.
 
 2002-06-20  Fernando Perez  <[e-mail]>
 
 	* IPython/genutils.py (timing): new function like
 	Mathematica's. Similar to time_test, but returns more info.
 
 2002-06-18  Fernando Perez  <[e-mail]>
 
 	* IPython/Magic.py (Magic.magic_save): modified @save and @r
 	according to Mike Heeter's suggestions.
 
 2002-06-16  Fernando Perez  <[e-mail]>
 
 	* IPython/GnuplotRuntime.py: Massive overhaul to the Gnuplot
 	system. GnuplotMagic is gone as a user-directory option. New files
 	make it easier to use all the gnuplot stuff both from external
 	programs as well as from IPython. Had to rewrite part of
 	hardcopy() b/c of a strange bug: often the ps files simply don't
 	get created, and require a repeat of the command (often several
 	times).
 
 	* IPython/ultraTB.py (AutoFormattedTB.__call__): changed to
 	resolve output channel at call time, so that if sys.stderr has
 	been redirected by user this gets honored.
 
 2002-06-13  Fernando Perez  <[e-mail]>
 
 	* IPython/Shell.py (IPShell.__init__): Changed IPythonShell to
 	IPShell. Kept a copy with the old names to avoid breaking people's
 	embedded code.
 
 	* IPython/ipython: simplified it to the bare minimum after
 	Holger's suggestions. Added info about how to use it in
 	PYTHONSTARTUP.
 
 	* IPython/Shell.py (IPythonShell): changed the options passing
 	from a string with funky %s replacements to a straight list. Maybe
 	a bit more typing, but it follows sys.argv conventions, so there's
 	less special-casing to remember.
 
 2002-06-12  Fernando Perez  <[e-mail]>
 
 	* IPython/Magic.py (Magic.magic_r): new magic auto-repeat
 	command. Thanks to a suggestion by Mike Heeter.
 	(Magic.magic_pfile): added behavior to look at filenames if given
 	arg is not a defined object.
 	(Magic.magic_save): New @save function to save code snippets. Also
 	a Mike Heeter idea.
 
 	* IPython/UserConfig/GnuplotMagic.py (plot): Improvements to
 	plot() and replot(). Much more convenient now, especially for
 	interactive use.
 
 	* IPython/Magic.py (Magic.magic_run): Added .py automatically to
 	filenames.
 
 2002-06-02  Fernando Perez  <[e-mail]>
 
 	* IPython/Struct.py (Struct.__init__): modified to admit
 	initialization via another struct.
 
 	* IPython/genutils.py (SystemExec.__init__): New stateful
 	interface to xsys and bq. Useful for writing system scripts.
 
 2002-05-30  Fernando Perez  <[e-mail]>
 
 	* MANIFEST.in: Changed docfile selection to exclude all the lyx
 	documents. This will make the user download smaller (it's getting
 	too big).
 
 2002-05-29  Fernando Perez  <[e-mail]>
 
 	* IPython/iplib.py (_FakeModule.__init__): New class introduced to
 	fix problems with shelve and pickle. Seems to work, but I don't
 	know if corner cases break it. Thanks to Mike Heeter
 	<korora-AT-SDF.LONESTAR.ORG> for the bug reports and test cases.
 
 2002-05-24  Fernando Perez  <[e-mail]>
 
 	* IPython/Magic.py (Macro.__init__): fixed magics embedded in
 	macros having broken.
 
 2002-05-21  Fernando Perez  <[e-mail]>
 
 	* IPython/Magic.py (Magic.magic_logstart): fixed recently
 	introduced logging bug: all history before logging started was
 	being written one character per line! This came from the redesign
 	of the input history as a special list which slices to strings,
 	not to lists.
 
 2002-05-20  Fernando Perez  <[e-mail]>
 
 	* IPython/Prompts.py (CachedOutput.__init__): made the color table
 	be an attribute of all classes in this module. The design of these
 	classes needs some serious overhauling.
 
 	* IPython/DPyGetOpt.py (DPyGetOpt.setPosixCompliance): fixed bug
 	which was ignoring '_' in option names.
 
 	* IPython/ultraTB.py (FormattedTB.__init__): Changed
 	'Verbose_novars' to 'Context' and made it the new default. It's a
 	bit more readable and also safer than verbose.
 
 	* IPython/PyColorize.py (Parser.__call__): Fixed coloring of
 	triple-quoted strings.
 
 	* IPython/OInspect.py (__all__): new module exposing the object
 	introspection facilities. Now the corresponding magics are dummy
 	wrappers around this. Having this module will make it much easier
 	to put these functions into our modified pdb.
 	This new object inspector system uses the new colorizing module,
 	so source code and other things are nicely syntax highlighted.
 
 2002-05-18  Fernando Perez  <[e-mail]>
 
 	* IPython/ColorANSI.py: Split the coloring tools into a separate
 	module so I can use them in other code easier (they were part of
 	ultraTB).
 
 2002-05-17  Fernando Perez  <[e-mail]>
 
 	* IPython/UserConfig/GnuplotMagic.py (magic_gp_set_instance):
 	fixed it to set the global 'g' also to the called instance, as
 	long as 'g' was still a gnuplot instance (so it doesn't overwrite
 	user's 'g' variables).
 
 	* IPython/iplib.py (InteractiveShell.__init__): Added In/Out
 	global variables (aliases to _ih,_oh) so that users which expect
 	In[5] or Out[7] to work aren't unpleasantly surprised.
 	(InputList.__getslice__): new class to allow executing slices of
 	input history directly. Very simple class, complements the use of
 	macros.
 
 2002-05-16  Fernando Perez  <[e-mail]>
 
 	* setup.py (docdirbase): make doc directory be just doc/IPython
 	without version numbers, it will reduce clutter for users.
 
 	* IPython/Magic.py (Magic.magic_run): Add explicit local dict to
 	execfile call to prevent possible memory leak. See for details:
 	http://mail.python.org/pipermail/python-list/2002-February/088476.html
 
 2002-05-15  Fernando Perez  <[e-mail]>
 
 	* IPython/Magic.py (Magic.magic_psource): made the object
 	introspection names be more standard: pdoc, pdef, pfile and
 	psource. They all print/page their output, and it makes
 	remembering them easier. Kept old names for compatibility as
 	aliases.
 
 2002-05-14  Fernando Perez  <[e-mail]>
 
 	* IPython/UserConfig/GnuplotMagic.py: I think I finally understood
 	what the mouse problem was. The trick is to use gnuplot with temp
 	files and NOT with pipes (for data communication), because having
 	both pipes and the mouse on is bad news.
 
 2002-05-13  Fernando Perez  <[e-mail]>
 
 	* IPython/Magic.py (Magic._ofind): fixed namespace order search
 	bug. Information would be reported about builtins even when
 	user-defined functions overrode them.
 
 2002-05-11  Fernando Perez  <[e-mail]>
 
 	* IPython/__init__.py (__all__): removed FlexCompleter from
 	__all__ so that things don't fail in platforms without readline.
 
 2002-05-10  Fernando Perez  <[e-mail]>
 
 	* IPython/__init__.py (__all__): removed numutils from __all__ b/c
 	it requires Numeric, effectively making Numeric a dependency for
 	IPython.
 
 	* Released 0.2.13
 
 	* IPython/Magic.py (Magic.magic_prun): big overhaul to the
 	profiler interface. Now all the major options from the profiler
 	module are directly supported in IPython, both for single
 	expressions (@prun) and for full programs (@run -p).
 
 2002-05-09  Fernando Perez  <[e-mail]>
 
 	* IPython/Magic.py (Magic.magic_doc): fixed to show docstrings of
 	magic properly formatted for screen.
 
 	* setup.py (make_shortcut): Changed things to put pdf version in
 	doc/ instead of doc/manual (had to change lyxport a bit).
 
 	* IPython/Magic.py (Profile.string_stats): made profile runs go
 	through pager (they are long and a pager allows searching, saving,
 	etc.)
 
 2002-05-08  Fernando Perez  <[e-mail]>
 
 	* Released 0.2.12
 
 2002-05-06  Fernando Perez  <[e-mail]>
 
 	* IPython/Magic.py (Magic.magic_hist): small bug fixed (recently
 	introduced); 'hist n1 n2' was broken.
 	(Magic.magic_pdb): added optional on/off arguments to @pdb
 	(Magic.magic_run): added option -i to @run, which executes code in
 	the IPython namespace instead of a clean one. Also added @irun as
 	an alias to @run -i.
 
 	* IPython/UserConfig/GnuplotMagic.py (magic_gp_set_instance):
 	fixed (it didn't really do anything, the namespaces were wrong).
 
 	* IPython/Debugger.py (__init__): Added workaround for python 2.1
 
 	* IPython/__init__.py (__all__): Fixed package namespace, now
 	'import IPython' does give access to IPython.<all> as
 	expected. Also renamed __release__ to Release.
 
 	* IPython/Debugger.py (__license__): created new Pdb class which
 	functions like a drop-in for the normal pdb.Pdb but does NOT
 	import readline by default. This way it doesn't muck up IPython's
 	readline handling, and now tab-completion finally works in the
 	debugger -- sort of. It completes things globally visible, but the
 	completer doesn't track the stack as pdb walks it. That's a bit
 	tricky, and I'll have to implement it later.
 
 2002-05-05  Fernando Perez  <[e-mail]>
 
 	* IPython/Magic.py (Magic.magic_oinfo): fixed formatting bug for
 	magic docstrings when printed via ? (explicit \'s were being
 	printed).
 
 	* IPython/ipmaker.py (make_IPython): fixed namespace
 	identification bug. Now variables loaded via logs or command-line
 	files are recognized in the interactive namespace by @who.
 
 	* IPython/iplib.py (InteractiveShell.safe_execfile): Fixed bug in
 	log replay system stemming from the string form of Structs.
 
 	* IPython/Magic.py (Macro.__init__): improved macros to properly
 	handle magic commands in them.
 	(Magic.magic_logstart): usernames are now expanded so 'logstart
 	~/mylog' now works.
 
 	* IPython/iplib.py (complete): fixed bug where paths starting with
 	'/' would be completed as magic names.
 
 2002-05-04  Fernando Perez  <[e-mail]>
 
 	* IPython/Magic.py (Magic.magic_run): added options -p and -f to
 	allow running full programs under the profiler's control.
 
 	* IPython/ultraTB.py (FormattedTB.__init__): Added Verbose_novars
 	mode to report exceptions verbosely but without formatting
 	variables. This addresses the issue of ipython 'freezing' (it's
 	not frozen, but caught in an expensive formatting loop) when huge
 	variables are in the context of an exception.
 	(VerboseTB.text): Added '--->' markers at line where exception was
 	triggered. Much clearer to read, especially in NoColor modes.
 
 	* IPython/Magic.py (Magic.magic_run): bugfix: -n option had been
 	implemented in reverse when changing to the new parse_options().
 
 2002-05-03  Fernando Perez  <[e-mail]>
 
 	* IPython/Magic.py (Magic.parse_options): new function so that
 	magics can parse options easier.
 	(Magic.magic_prun): new function similar to profile.run(),
 	suggested by Chris Hart.
 	(Magic.magic_cd): fixed behavior so that it only changes if
 	directory actually is in history.
 
 	* IPython/usage.py (__doc__): added information about potential
 	slowness of Verbose exception mode when there are huge data
 	structures to be formatted (thanks to Archie Paulson).
 
 	* IPython/ipmaker.py (make_IPython): Changed default logging
 	(when simply called with -log) to use curr_dir/ipython.log in
 	rotate mode. Fixed crash which was occuring with -log before
 	(thanks to Jim Boyle).
 
 2002-05-01  Fernando Perez  <[e-mail]>
 
 	* Released 0.2.11 for these fixes (mainly the ultraTB one which
 	was nasty -- though somewhat of a corner case).
 
 	* IPython/ultraTB.py (AutoFormattedTB.text): renamed __text to
 	text (was a bug).
 
 2002-04-30  Fernando Perez  <[e-mail]>
 
 	* IPython/UserConfig/GnuplotMagic.py (magic_gp): Minor fix to add
 	a print after ^D or ^C from the user so that the In[] prompt
 	doesn't over-run the gnuplot one.
 
 2002-04-29  Fernando Perez  <[e-mail]>
 
 	* Released 0.2.10
 
 	* IPython/__release__.py (version): get date dynamically.
 
 	* Misc. documentation updates thanks to Arnd's comments. Also ran
 	a full spellcheck on the manual (hadn't been done in a while).
 
 2002-04-27  Fernando Perez  <[e-mail]>
 
 	* IPython/Magic.py (Magic.magic_logstart): Fixed bug where
 	starting a log in mid-session would reset the input history list.
 
 2002-04-26  Fernando Perez  <[e-mail]>
 
 	* IPython/iplib.py (InteractiveShell.wait): Fixed bug where not
 	all files were being included in an update. Now anything in
 	UserConfig that matches [A-Za-z]*.py will go (this excludes
 	__init__.py)
 
 2002-04-25  Fernando Perez  <[e-mail]>
 
 	* IPython/iplib.py (InteractiveShell.__init__): Added __IPYTHON__
 	to __builtins__ so that any form of embedded or imported code can
 	test for being inside IPython.
 
 	* IPython/UserConfig/GnuplotMagic.py: (magic_gp_set_instance):
 	changed to GnuplotMagic because it's now an importable module,
 	this makes the name follow that of the standard Gnuplot module.
 	GnuplotMagic can now be loaded at any time in mid-session.
 
 2002-04-24  Fernando Perez  <[e-mail]>
 
 	* IPython/numutils.py: removed SIUnits. It doesn't properly set
 	the globals (IPython has its own namespace) and the
 	PhysicalQuantity stuff is much better anyway.
 
 	* IPython/UserConfig/example-gnuplot.py (g2): Added gnuplot
 	embedding example to standard user directory for
 	distribution. Also put it in the manual.
 
 	* IPython/numutils.py (gnuplot_exec): Changed to take a gnuplot
 	instance as first argument (so it doesn't rely on some obscure
 	hidden global).
 
 	* IPython/UserConfig/ipythonrc.py: put () back in accepted
 	delimiters. While it prevents ().TAB from working, it allows
 	completions in open (... expressions. This is by far a more common
 	case.
 
 2002-04-23  Fernando Perez  <[e-mail]>
 
 	* IPython/Extensions/InterpreterPasteInput.py: new
 	syntax-processing module for pasting lines with >>> or ... at the
 	start.
 
 	* IPython/Extensions/PhysicalQ_Interactive.py
 	(PhysicalQuantityInteractive.__int__): fixed to work with either
 	Numeric or math.
 
 	* IPython/UserConfig/ipythonrc-numeric.py: reorganized the
 	provided profiles. Now we have:
 	-math -> math module as * and cmath with its own namespace.
 	-numeric -> Numeric as *, plus gnuplot & grace
 	-physics -> same as before
 
 	* IPython/Magic.py (Magic.magic_magic): Fixed bug where
 	user-defined magics wouldn't be found by @magic if they were
 	defined as class methods. Also cleaned up the namespace search
 	logic and the string building (to use %s instead of many repeated
 	string adds).
 
 	* IPython/UserConfig/example-magic.py (magic_foo): updated example
 	of user-defined magics to operate with class methods (cleaner, in
 	line with the gnuplot code).
 
 2002-04-22  Fernando Perez  <[e-mail]>
 
 	* setup.py: updated dependency list so that manual is updated when
 	all included files change.
 
 	* IPython/ipmaker.py (make_IPython): Fixed bug which was ignoring
 	the delimiter removal option (the fix is ugly right now).
 
 	* IPython/UserConfig/ipythonrc-physics.py: simplified not to load
 	all of the math profile (quicker loading, no conflict between
 	g-9.8 and g-gnuplot).
 
 	* IPython/CrashHandler.py (CrashHandler.__call__): changed default
 	name of post-mortem files to IPython_crash_report.txt.
 
 	* Cleanup/update of the docs. Added all the new readline info and
 	formatted all lists as 'real lists'.
 
 	* IPython/ipmaker.py (make_IPython): removed now-obsolete
 	tab-completion options, since the full readline parse_and_bind is
 	now accessible.
 
 	* IPython/iplib.py (InteractiveShell.init_readline): Changed
 	handling of readline options. Now users can specify any string to
 	be passed to parse_and_bind(), as well as the delimiters to be
 	removed.
 	(InteractiveShell.__init__): Added __name__ to the global
 	namespace so that things like Itpl which rely on its existence
 	don't crash.
 	(InteractiveShell._prefilter): Defined the default with a _ so
 	that prefilter() is easier to override, while the default one
 	remains available.
 
 2002-04-18  Fernando Perez  <[e-mail]>
 
 	* Added information about pdb in the docs.
 
 2002-04-17  Fernando Perez  <[e-mail]>
 
 	* IPython/ipmaker.py (make_IPython): added rc_override option to
 	allow passing config options at creation time which may override
 	anything set in the config files or command line. This is
 	particularly useful for configuring embedded instances.
 
 2002-04-15  Fernando Perez  <[e-mail]>
 
 	* IPython/Logger.py (Logger.log): Fixed a nasty bug which could
 	crash embedded instances because of the input cache falling out of
 	sync with the output counter.
 
 	* IPython/Shell.py (IPythonShellEmbed.__init__): added a debug
 	mode which calls pdb after an uncaught exception in IPython itself.
 
 2002-04-14  Fernando Perez  <[e-mail]>
 
 	* IPython/iplib.py (InteractiveShell.showtraceback): pdb mucks up
 	readline, fix it back after each call.
 
 	* IPython/ultraTB.py (AutoFormattedTB.__text): made text a private
 	method to force all access via __call__(), which guarantees that
 	traceback references are properly deleted.
 
 	* IPython/Prompts.py (CachedOutput._display): minor fixes to
 	improve printing when pprint is in use.
 
 2002-04-13  Fernando Perez  <[e-mail]>
 
 	* IPython/Shell.py (IPythonShellEmbed.__call__): SystemExit
 	exceptions aren't caught anymore. If the user triggers one, he
 	should know why he's doing it and it should go all the way up,
 	just like any other exception. So now @abort will fully kill the
 	embedded interpreter and the embedding code (unless that happens
 	to catch SystemExit).
 
 	* IPython/ultraTB.py (VerboseTB.__init__): added a call_pdb flag
 	and a debugger() method to invoke the interactive pdb debugger
 	after printing exception information. Also added the corresponding
 	-pdb option and @pdb magic to control this feature, and updated
 	the docs. After a suggestion from Christopher Hart
 	(hart-AT-caltech.edu).
 
 2002-04-12  Fernando Perez  <[e-mail]>
 
 	* IPython/Shell.py (IPythonShellEmbed.__init__): modified to use
 	the exception handlers defined by the user (not the CrashHandler)
 	so that user exceptions don't trigger an ipython bug report.
 
 	* IPython/ultraTB.py (ColorTB.__init__): made the color scheme
 	configurable (it should have always been so).
 
 2002-03-26  Fernando Perez  <[e-mail]>
 
 	* IPython/Shell.py (IPythonShellEmbed.__call__): many changes here
 	and there to fix embedding namespace issues. This should all be
 	done in a more elegant way.
 
 2002-03-25  Fernando Perez  <[e-mail]>
 
 	* IPython/genutils.py (get_home_dir): Try to make it work under
 	win9x also.
 
 2002-03-20  Fernando Perez  <[e-mail]>
 
 	* IPython/Shell.py (IPythonShellEmbed.__init__): leave
 	sys.displayhook untouched upon __init__.
 
 2002-03-19  Fernando Perez  <[e-mail]>
 
 	* Released 0.2.9 (for embedding bug, basically).
 
 	* IPython/Shell.py (IPythonShellEmbed.__call__): Trap SystemExit
 	exceptions so that enclosing shell's state can be restored.
 
 	* Changed magic_gnuplot.py to magic-gnuplot.py to standardize
 	naming conventions in the .ipython/ dir.
 
 	* IPython/iplib.py (InteractiveShell.init_readline): removed '-'
 	from delimiters list so filenames with - in them get expanded.
 
 	* IPython/Shell.py (IPythonShellEmbed.__call__): fixed bug with
 	sys.displayhook not being properly restored after an embedded call.
 
  2002-03-18  Fernando Perez  <[e-mail]>
 
 	* Released 0.2.8
 
 	* IPython/iplib.py (InteractiveShell.user_setup): fixed bug where
 	some files weren't being included in a -upgrade.
 	(InteractiveShell.init_readline): Added 'set show-all-if-ambiguous
 	on' so that the first tab completes.
 	(InteractiveShell.handle_magic): fixed bug with spaces around
 	quotes breaking many magic commands.
 
 	* setup.py: added note about ignoring the syntax error messages at
 	installation.
 
 	* IPython/UserConfig/magic_gnuplot.py (magic_gp): finished
 	streamlining the gnuplot interface, now there's only one magic @gp.
 
 2002-03-17  Fernando Perez  <[e-mail]>
 
 	* IPython/UserConfig/magic_gnuplot.py: new name for the
 	example-magic_pm.py file. Much enhanced system, now with a shell
 	for communicating directly with gnuplot, one command at a time.
 
 	* IPython/Magic.py (Magic.magic_run): added option -n to prevent
 	setting __name__=='__main__'.
 
 	* IPython/UserConfig/example-magic_pm.py (magic_pm): Added
 	mini-shell for accessing gnuplot from inside ipython. Should
 	extend it later for grace access too. Inspired by Arnd's
 	suggestion.
 
 	* IPython/iplib.py (InteractiveShell.handle_magic): fixed bug when
 	calling magic functions with () in their arguments. Thanks to Arnd
 	Baecker for pointing this to me.
 
 	* IPython/numutils.py (sum_flat): fixed bug. Would recurse
 	infinitely for integer or complex arrays (only worked with floats).
 
 2002-03-16  Fernando Perez  <[e-mail]>
 
 	* setup.py: Merged setup and setup_windows into a single script
 	which properly handles things for windows users.
 
 2002-03-15  Fernando Perez  <[e-mail]>
 
 	* Big change to the manual: now the magics are all automatically
 	documented. This information is generated from their docstrings
 	and put in a latex file included by the manual lyx file. This way
 	we get always up to date information for the magics. The manual
 	now also has proper version information, also auto-synced.
 
 	For this to work, an undocumented --magic_docstrings option was added.
 
 2002-03-13  Fernando Perez  <[e-mail]>
 
 	* IPython/ultraTB.py (TermColors): fixed problem with dark colors
 	under CDE terminals. An explicit ;2 color reset is needed in the escapes.
 
 2002-03-12  Fernando Perez  <[e-mail]>
 
 	* IPython/ultraTB.py (TermColors): changed color escapes again to
 	fix the (old, reintroduced) line-wrapping bug. Basically, if
 	\001..\002 aren't given in the color escapes, lines get wrapped
 	weirdly. But giving those screws up old xterms and emacs terms. So
 	I added some logic for emacs terms to be ok, but I can't identify old
 	xterms separately ($TERM=='xterm' for many terminals, like konsole).
 
 2002-03-10  Fernando Perez  <[e-mail]>
 
 	* IPython/usage.py (__doc__): Various documentation cleanups and
 	updates, both in usage docstrings and in the manual.
 
 	* IPython/Prompts.py (CachedOutput.set_colors): cleanups for
 	handling of caching. Set minimum acceptabe value for having a
 	cache at 20 values.
 
 	* IPython/iplib.py (InteractiveShell.user_setup): moved the
 	install_first_time function to a method, renamed it and added an
 	'upgrade' mode. Now people can update their config directory with
 	a simple command line switch (-upgrade, also new).
 
 	* IPython/Magic.py (Magic.magic_pfile): Made @pfile an alias to
 	@file (convenient for automagic users under Python >= 2.2). 
 	Removed @files (it seemed more like a plural than an abbrev. of
 	'file show').
 
 	* IPython/iplib.py (install_first_time): Fixed crash if there were
 	backup files ('~') in .ipython/ install directory.
 
 	* IPython/ipmaker.py (make_IPython): fixes for new prompt
 	system. Things look fine, but these changes are fairly
 	intrusive. Test them for a few days.
 
 	* IPython/Prompts.py (CachedOutput.__init__): Massive rewrite of
 	the prompts system. Now all in/out prompt strings are user
 	controllable. This is particularly useful for embedding, as one
 	can tag embedded instances with particular prompts. 
 
 	Also removed global use of sys.ps1/2, which now allows nested
 	embeddings without any problems. Added command-line options for
 	the prompt strings.
 
 2002-03-08  Fernando Perez  <[e-mail]>
 
 	* IPython/UserConfig/example-embed-short.py (ipshell): added
 	example file with the bare minimum code for embedding.
 
 	* IPython/Shell.py (IPythonShellEmbed.set_dummy_mode): added
 	functionality for the embeddable shell to be activated/deactivated
 	either globally or at each call.
 
 	* IPython/Prompts.py (Prompt1.auto_rewrite): Fixes the problem of
 	rewriting the prompt with '--->' for auto-inputs with proper
 	coloring. Now the previous UGLY hack in handle_auto() is gone, and
 	this is handled by the prompts class itself, as it should.
 
 2002-03-05  Fernando Perez  <[e-mail]>
 
 	* IPython/Magic.py (Magic.magic_logstart): Changed @log to
 	@logstart to avoid name clashes with the math log function.
 
 	* Big updates to X/Emacs section of the manual.
 
 	* Removed ipython_emacs. Milan explained to me how to pass
 	arguments to ipython through Emacs. Some day I'm going to end up
 	learning some lisp...
 
 2002-03-04  Fernando Perez  <[e-mail]>
 
 	* IPython/ipython_emacs: Created script to be used as the
 	py-python-command Emacs variable so we can pass IPython
 	parameters. I can't figure out how to tell Emacs directly to pass
 	parameters to IPython, so a dummy shell script will do it.
 
 	Other enhancements made for things to work better under Emacs'
 	various types of terminals. Many thanks to Milan Zamazal
 	<pdm-AT-zamazal.org> for all the suggestions and pointers.
 
 2002-03-01  Fernando Perez  <[e-mail]>
 
 	* IPython/ipmaker.py (make_IPython): added a --readline! option so
 	that loading of readline is now optional. This gives better
 	control to emacs users.
 
 	* IPython/ultraTB.py (__date__): Modified color escape sequences
 	and now things work fine under xterm and in Emacs' term buffers
 	(though not shell ones). Well,  in emacs you get colors, but all
 	seem to be 'light' colors (no difference between dark and light
 	ones). But the garbage chars are gone, and also in xterms. It
 	seems that now I'm using 'cleaner' ansi sequences.
 
 2002-02-21  Fernando Perez  <[e-mail]>
 
 	* Released 0.2.7 (mainly to publish the scoping fix).
 	
 	* IPython/Logger.py (Logger.logstate): added. A corresponding
 	@logstate magic was created.
 
 	* IPython/Magic.py: fixed nested scoping problem under Python
 	2.1.x (automagic wasn't working).
 
 2002-02-20  Fernando Perez  <[e-mail]>
 
 	* Released 0.2.6.
 
 	* IPython/OutputTrap.py (OutputTrap.__init__): added a 'quiet'
 	option so that logs can come out without any headers at all.
 
 	* IPython/UserConfig/ipythonrc-scipy.py: created a profile for
 	SciPy.
 
 	* IPython/iplib.py (InteractiveShell.embed_mainloop): Changed so
 	that embedded IPython calls don't require vars() to be explicitly
 	passed. Now they are extracted from the caller's frame (code
 	snatched from Eric Jones' weave). Added better documentation to
 	the section on embedding and the example file.
 
 	* IPython/genutils.py (page): Changed so that under emacs, it just
 	prints the string. You can then page up and down in the emacs
 	buffer itself. This is how the builtin help() works.
 
 	* IPython/Prompts.py (CachedOutput.__call__): Fixed issue with
 	macro scoping: macros need to be executed in the user's namespace
 	to work as if they had been typed by the user.
 
 	* IPython/Magic.py (Magic.magic_macro): Changed macros so they
 	execute automatically (no need to type 'exec...'). They then
 	behave like 'true macros'. The printing system was also modified
 	for this to work.
 
 2002-02-19  Fernando Perez  <[e-mail]>
 
 	* IPython/genutils.py (page_file): new function for paging files
 	in an OS-independent way. Also necessary for file viewing to work
 	well inside Emacs buffers.
 	(page): Added checks for being in an emacs buffer.
 	(page): fixed bug for Windows ($TERM isn't set in Windows). Fixed
 	same bug in iplib.
 
 2002-02-18  Fernando Perez  <[e-mail]>
 
 	* IPython/iplib.py (InteractiveShell.init_readline): modified use
 	of readline so that IPython can work inside an Emacs buffer.
 
 	* IPython/ultraTB.py (AutoFormattedTB.__call__): some fixes to
 	method signatures (they weren't really bugs, but it looks cleaner
 	and keeps PyChecker happy).
 
 	* IPython/ipmaker.py (make_IPython): added hooks Struct to __IP
 	for implementing various user-defined hooks. Currently only
 	display is done.
 
 	* IPython/Prompts.py (CachedOutput._display): changed display
 	functions so that they can be dynamically changed by users easily.
 
 	* IPython/Extensions/numeric_formats.py (num_display): added an
 	extension for printing NumPy arrays in flexible manners. It
 	doesn't do anything yet, but all the structure is in
 	place. Ultimately the plan is to implement output format control
 	like in Octave.
 
 	* IPython/Magic.py (Magic.lsmagic): changed so that bound magic
 	methods are found at run-time by all the automatic machinery.
 
 2002-02-17  Fernando Perez  <[e-mail]>
 
 	* setup_Windows.py (make_shortcut): documented. Cleaned up the
 	whole file a little.
 
 	* ToDo: closed this document. Now there's a new_design.lyx
 	document for all new ideas. Added making a pdf of it for the
 	end-user distro.
 
 	* IPython/Logger.py (Logger.switch_log): Created this to replace
 	logon() and logoff(). It also fixes a nasty crash reported by 
 	Philip Hisley <compsys-AT-starpower.net>. Many thanks to him.
 
 	* IPython/iplib.py (complete): got auto-completion to work with
 	automagic (I had wanted this for a long time).
 
 	* IPython/Magic.py (Magic.magic_files): Added @files as an alias
 	to @file, since file() is now a builtin and clashes with automagic
 	for @file.
 
 	* Made some new files: Prompts, CrashHandler, Magic, Logger. All
 	of this was previously in iplib, which had grown to more than 2000
 	lines, way too long. No new functionality, but it makes managing
 	the code a bit easier.
 
 	* IPython/iplib.py (IPythonCrashHandler.__call__): Added version
 	information to crash reports.
 
 2002-02-12  Fernando Perez  <[e-mail]>
 
 	* Released 0.2.5.
 
 2002-02-11  Fernando Perez  <[e-mail]>
 
 	* Wrote a relatively complete Windows installer. It puts
 	everything in place, creates Start Menu entries and fixes the
 	color issues. Nothing fancy, but it works.
 
 2002-02-10  Fernando Perez  <[e-mail]>
 
 	* IPython/iplib.py (InteractiveShell.safe_execfile): added an
 	os.path.expanduser() call so that we can type @run ~/myfile.py and
 	have thigs work as expected.
 
 	* IPython/genutils.py (page): fixed exception handling so things
 	work both in Unix and Windows correctly. Quitting a pager triggers
 	an IOError/broken pipe in Unix, and in windows not finding a pager
 	is also an IOError, so I had to actually look at the return value
 	of the exception, not just the exception itself. Should be ok now.
 
 	* IPython/ultraTB.py (ColorSchemeTable.set_active_scheme):
 	modified to allow case-insensitive color scheme changes.
 
 2002-02-09  Fernando Perez  <[e-mail]>
 
 	* IPython/genutils.py (native_line_ends): new function to leave
 	user config files with os-native line-endings.
 
 	* README and manual updates.
 
 	* IPython/genutils.py: fixed unicode bug: use types.StringTypes
 	instead of StringType to catch Unicode strings.
 
 	* IPython/genutils.py (filefind): fixed bug for paths with
 	embedded spaces (very common in Windows).
 
 	* IPython/ipmaker.py (make_IPython): added a '.ini' to the rc
 	files under Windows, so that they get automatically associated
 	with a text editor. Windows makes it a pain to handle
 	extension-less files.
 
 	* IPython/iplib.py (InteractiveShell.init_readline): Made the
 	warning about readline only occur for Posix. In Windows there's no
 	way to get readline, so why bother with the warning.
 
 	* IPython/Struct.py (Struct.__str__): fixed to use self.__dict__
 	for __str__ instead of dir(self), since dir() changed in 2.2.
 
 	* Ported to Windows! Tested on XP, I suspect it should work fine
 	on NT/2000, but I don't think it will work on 98 et al. That
 	series of Windows is such a piece of junk anyway that I won't try
 	porting it there. The XP port was straightforward, showed a few
 	bugs here and there (fixed all), in particular some string
 	handling stuff which required considering Unicode strings (which
 	Windows uses). This is good, but hasn't been too tested :) No
 	fancy installer yet, I'll put a note in the manual so people at
 	least make manually a shortcut.
 
 	* IPython/iplib.py (Magic.magic_colors): Unified the color options
 	into a single one, "colors". This now controls both prompt and
 	exception color schemes, and can be changed both at startup
 	(either via command-line switches or via ipythonrc files) and at
 	runtime, with @colors.
 	(Magic.magic_run): renamed @prun to @run and removed the old
 	@run. The two were too similar to warrant keeping both.
 
 2002-02-03  Fernando Perez  <[e-mail]>
 
 	* IPython/iplib.py (install_first_time): Added comment on how to
 	configure the color options for first-time users. Put a <return>
 	request at the end so that small-terminal users get a chance to
 	read the startup info.
 
 2002-01-23  Fernando Perez  <[e-mail]>
 
 	* IPython/iplib.py (CachedOutput.update): Changed output memory
 	variable names from _o,_oo,_ooo,_o<n> to simply _,__,___,_<n>. For
 	input history we still use _i. Did this b/c these variable are
 	very commonly used in interactive work, so the less we need to
 	type the better off we are.
 	(Magic.magic_prun): updated @prun to better handle the namespaces
 	the file will run in, including a fix for __name__ not being set
 	before.
 
 2002-01-20  Fernando Perez  <[e-mail]>
 
 	* IPython/ultraTB.py (VerboseTB.linereader): Fixed printing of
 	extra garbage for Python 2.2. Need to look more carefully into
 	this later.
 
 2002-01-19  Fernando Perez  <[e-mail]>
 
 	* IPython/iplib.py (InteractiveShell.showtraceback): fixed to
 	display SyntaxError exceptions properly formatted when they occur
 	(they can be triggered by imported code).
 
 2002-01-18  Fernando Perez  <[e-mail]>
 
 	* IPython/iplib.py (InteractiveShell.safe_execfile): now
 	SyntaxError exceptions are reported nicely formatted, instead of
 	spitting out only offset information as before.
 	(Magic.magic_prun): Added the @prun function for executing
 	programs with command line args inside IPython.
 
 2002-01-16  Fernando Perez  <[e-mail]>
 
 	* IPython/iplib.py (Magic.magic_hist): Changed @hist and @dhist
 	to *not* include the last item given in a range. This brings their
 	behavior in line with Python's slicing: 
 	  a[n1:n2] -> a[n1]...a[n2-1]
 	It may be a bit less convenient, but I prefer to stick to Python's
 	conventions *everywhere*, so users never have to wonder.
 	(Magic.magic_macro): Added @macro function to ease the creation of
 	macros.
 
 2002-01-05  Fernando Perez  <[e-mail]>
 
 	* Released 0.2.4.
 
 	* IPython/iplib.py (Magic.magic_pdef): 
 	(InteractiveShell.safe_execfile): report magic lines and error
 	lines without line numbers so one can easily copy/paste them for
 	re-execution.
 
 	* Updated manual with recent changes.
 
 	* IPython/iplib.py (Magic.magic_oinfo): added constructor
 	docstring printing when class? is called. Very handy for knowing
 	how to create class instances (as long as __init__ is well
 	documented, of course :)
 	(Magic.magic_doc): print both class and constructor docstrings.
 	(Magic.magic_pdef): give constructor info if passed a class and
 	__call__ info for callable object instances.
 
 2002-01-04  Fernando Perez  <[e-mail]>
 
 	* Made deep_reload() off by default. It doesn't always work
 	exactly as intended, so it's probably safer to have it off. It's
 	still available as dreload() anyway, so nothing is lost.
 
 2002-01-02  Fernando Perez  <[e-mail]>
 
 	* Released 0.2.3 (contacted R.Singh at CU about biopython course,
 	so I wanted an updated release).
 
 2001-12-27  Fernando Perez  <[e-mail]>
 
 	* IPython/iplib.py (InteractiveShell.interact): Added the original
 	code from 'code.py' for this module in order to change the
 	handling of a KeyboardInterrupt. This was necessary b/c otherwise
 	the history cache would break when the user hit Ctrl-C, and
 	interact() offers no way to add any hooks to it.
 
 2001-12-23  Fernando Perez  <[e-mail]>
 
 	* setup.py: added check for 'MANIFEST' before trying to remove
 	it. Thanks to Sean Reifschneider.
 
 2001-12-22  Fernando Perez  <[e-mail]>
 
 	* Released 0.2.2.
 
 	* Finished (reasonably) writing the manual. Later will add the
 	python-standard navigation stylesheets, but for the time being
 	it's fairly complete. Distribution will include html and pdf
 	versions.
 
 	* Bugfix: '.' wasn't being added to sys.path. Thanks to Prabhu
 	(MayaVi author).
 
 2001-12-21  Fernando Perez  <[e-mail]>
 
 	* Released 0.2.1. Barring any nasty bugs, this is it as far as a
 	good public release, I think (with the manual and the distutils
 	installer). The manual can use some work, but that can go
 	slowly. Otherwise I think it's quite nice for end users. Next
 	summer, rewrite the guts of it...
 
 	* Changed format of ipythonrc files to use whitespace as the
 	separator instead of an explicit '='. Cleaner.
 
 2001-12-20  Fernando Perez  <[e-mail]>
 
 	* Started a manual in LyX. For now it's just a quick merge of the
 	various internal docstrings and READMEs. Later it may grow into a
 	nice, full-blown manual.
 
 	* Set up a distutils based installer. Installation should now be
 	trivially simple for end-users.
 
 2001-12-11  Fernando Perez  <[e-mail]>
 
 	* Released 0.2.0. First public release, announced it at
 	comp.lang.python. From now on, just bugfixes...
 
 	* Went through all the files, set copyright/license notices and
 	cleaned up things. Ready for release.
 
 2001-12-10  Fernando Perez  <[e-mail]>
 
 	* Changed the first-time installer not to use tarfiles. It's more
 	robust now and less unix-dependent. Also makes it easier for
 	people to later upgrade versions.
 
 	* Changed @exit to @abort to reflect the fact that it's pretty
 	brutal (a sys.exit()). The difference between @abort and Ctrl-D
 	becomes significant only when IPyhton is embedded: in that case,
 	C-D closes IPython only, but @abort kills the enclosing program
 	too (unless it had called IPython inside a try catching
 	SystemExit).
 
 	* Created Shell module which exposes the actuall IPython Shell
 	classes, currently the normal and the embeddable one. This at
 	least offers a stable interface we won't need to change when
 	(later) the internals are rewritten. That rewrite will be confined
 	to iplib and ipmaker, but the Shell interface should remain as is.
 
 	* Added embed module which offers an embeddable IPShell object,
 	useful to fire up IPython *inside* a running program. Great for
 	debugging or dynamical data analysis.
 
 2001-12-08  Fernando Perez  <[e-mail]>
 
 	* Fixed small bug preventing seeing info from methods of defined
 	objects (incorrect namespace in _ofind()).
 
 	* Documentation cleanup. Moved the main usage docstrings to a
 	separate file, usage.py (cleaner to maintain, and hopefully in the
 	future some perlpod-like way of producing interactive, man and
 	html docs out of it will be found).
 
 	* Added @profile to see your profile at any time.
 
 	* Added @p as an alias for 'print'. It's especially convenient if
 	using automagic ('p x' prints x).
 
 	* Small cleanups and fixes after a pychecker run.
 
 	* Changed the @cd command to handle @cd - and @cd -<n> for
 	visiting any directory in _dh.
 
 	* Introduced _dh, a history of visited directories. @dhist prints
 	it out with numbers.
 
 2001-12-07  Fernando Perez  <[e-mail]>
 
 	* Released 0.1.22
 
 	* Made initialization a bit more robust against invalid color
 	options in user input (exit, not traceback-crash).
 
 	* Changed the bug crash reporter to write the report only in the
 	user's .ipython directory. That way IPython won't litter people's
 	hard disks with crash files all over the place. Also print on
 	screen the necessary mail command.
 
 	* With the new ultraTB, implemented LightBG color scheme for light
 	background terminals. A lot of people like white backgrounds, so I
 	guess we should at least give them something readable.
 
 2001-12-06  Fernando Perez  <[e-mail]>
 
 	* Modified the structure of ultraTB. Now there's a proper class
 	for tables of color schemes which allow adding schemes easily and
 	switching the active scheme without creating a new instance every
 	time (which was ridiculous). The syntax for creating new schemes
 	is also cleaner. I think ultraTB is finally done, with a clean
 	class structure. Names are also much cleaner (now there's proper
 	color tables, no need for every variable to also have 'color' in
 	its name).
 
 	* Broke down genutils into separate files. Now genutils only
 	contains utility functions, and classes have been moved to their
 	own files (they had enough independent functionality to warrant
 	it): ConfigLoader, OutputTrap, Struct.
 
 2001-12-05  Fernando Perez  <[e-mail]>
 
 	* IPython turns 21! Released version 0.1.21, as a candidate for
 	public consumption. If all goes well, release in a few days.
 
 	* Fixed path bug (files in Extensions/ directory wouldn't be found
 	unless IPython/ was explicitly in sys.path).
 
 	* Extended the FlexCompleter class as MagicCompleter to allow
 	completion of @-starting lines.
 
 	* Created __release__.py file as a central repository for release
 	info that other files can read from.
 
 	* Fixed small bug in logging: when logging was turned on in
 	mid-session, old lines with special meanings (!@?) were being
 	logged without the prepended comment, which is necessary since
 	they are not truly valid python syntax. This should make session
 	restores produce less errors.
 
 	* The namespace cleanup forced me to make a FlexCompleter class
 	which is nothing but a ripoff of rlcompleter, but with selectable
 	namespace (rlcompleter only works in __main__.__dict__). I'll try
 	to submit a note to the authors to see if this change can be
 	incorporated in future rlcompleter releases (Dec.6: done)
 
 	* More fixes to namespace handling. It was a mess! Now all
 	explicit references to __main__.__dict__ are gone (except when
 	really needed) and everything is handled through the namespace
 	dicts in the IPython instance. We seem to be getting somewhere
 	with this, finally...
 
 	* Small documentation updates.
 
 	* Created the Extensions directory under IPython (with an
 	__init__.py). Put the PhysicalQ stuff there. This directory should
 	be used for all special-purpose extensions.
 
 	* File renaming:
 	  ipythonlib --> ipmaker
 	  ipplib     --> iplib
 	This makes a bit more sense in terms of what these files actually do.
 
 	* Moved all the classes and functions in ipythonlib to ipplib, so
 	now ipythonlib only has make_IPython(). This will ease up its
 	splitting in smaller functional chunks later.
 
 	* Cleaned up (done, I think) output of @whos. Better column
 	formatting, and now shows str(var) for as much as it can, which is
 	typically what one gets with a 'print var'.
 
 2001-12-04  Fernando Perez  <[e-mail]>
 
 	* Fixed namespace problems. Now builtin/IPyhton/user names get
 	properly reported in their namespace. Internal namespace handling
 	is finally getting decent (not perfect yet, but much better than
 	the ad-hoc mess we had).
 
 	* Removed -exit option. If people just want to run a python
 	script, that's what the normal interpreter is for. Less
 	unnecessary options, less chances for bugs.
 
 	* Added a crash handler which generates a complete post-mortem if
 	IPython crashes. This will help a lot in tracking bugs down the
 	road.
 
 	* Fixed nasty bug in auto-evaluation part of prefilter(). Names
 	which were boud to functions being reassigned would bypass the
 	logger, breaking the sync of _il with the prompt counter. This
 	would then crash IPython later when a new line was logged.
 
 2001-12-02  Fernando Perez  <[e-mail]>
 
 	* Made IPython a package. This means people don't have to clutter
 	their sys.path with yet another directory. Changed the INSTALL
 	file accordingly.
 
 	* Cleaned up the output of @who_ls, @who and @whos. @who_ls now
 	sorts its output (so @who shows it sorted) and @whos formats the
 	table according to the width of the first column. Nicer, easier to
 	read. Todo: write a generic table_format() which takes a list of
 	lists and prints it nicely formatted, with optional row/column
 	separators and proper padding and justification. 
 
 	* Released 0.1.20
 
 	* Fixed bug in @log which would reverse the inputcache list (a
 	copy operation was missing).
 
 	* Code cleanup. @config was changed to use page(). Better, since
 	its output is always quite long.
 
 	* Itpl is back as a dependency. I was having too many problems
 	getting the parametric aliases to work reliably, and it's just
 	easier to code weird string operations with it than playing %()s
 	games. It's only ~6k, so I don't think it's too big a deal.
 
 	* Found (and fixed) a very nasty bug with history. !lines weren't
 	getting cached, and the out of sync caches would crash
 	IPython. Fixed it by reorganizing the prefilter/handlers/logger
 	division of labor a bit better. Bug fixed, cleaner structure.
 
 2001-12-01  Fernando Perez  <[e-mail]>
 
 	* Released 0.1.19
 
 	* Added option -n to @hist to prevent line number printing. Much
 	easier to copy/paste code this way.
 
 	* Created global _il to hold the input list. Allows easy
 	re-execution of blocks of code by slicing it (inspired by Janko's
 	comment on 'macros').
 
 	* Small fixes and doc updates.
 
 	* Rewrote @history function (was @h). Renamed it to @hist, @h is
 	much too fragile with automagic. Handles properly multi-line
 	statements and takes parameters.
 
 2001-11-30  Fernando Perez  <[e-mail]>
 
 	* Version 0.1.18 released.
 
 	* Fixed nasty namespace bug in initial module imports.
 
 	* Added copyright/license notes to all code files (except
 	DPyGetOpt). For the time being, LGPL. That could change.
 
 	* Rewrote a much nicer README, updated INSTALL, cleaned up
 	ipythonrc-* samples.
 
 	* Overall code/documentation cleanup. Basically ready for
 	release. Only remaining thing: licence decision (LGPL?).
 
 	* Converted load_config to a class, ConfigLoader. Now recursion
 	control is better organized. Doesn't include the same file twice.
 
 2001-11-29  Fernando Perez  <[e-mail]>
 
 	* Got input history working. Changed output history variables from
 	_p to _o so that _i is for input and _o for output. Just cleaner
 	convention.
 
 	* Implemented parametric aliases. This pretty much allows the
 	alias system to offer full-blown shell convenience, I think.
 
 	* Version 0.1.17 released, 0.1.18 opened.
 
 	* dot_ipython/ipythonrc (alias): added documentation.
 	(xcolor): Fixed small bug (xcolors -> xcolor)
 
 	* Changed the alias system. Now alias is a magic command to define
 	aliases just like the shell. Rationale: the builtin magics should
 	be there for things deeply connected to IPython's
 	architecture. And this is a much lighter system for what I think
 	is the really important feature: allowing users to define quickly
 	magics that will do shell things for them, so they can customize
 	IPython easily to match their work habits. If someone is really
 	desperate to have another name for a builtin alias, they can
 	always use __IP.magic_newname = __IP.magic_oldname. Hackish but
 	works.
 
 2001-11-28  Fernando Perez  <[e-mail]>
 
 	* Changed @file so that it opens the source file at the proper
 	line. Since it uses less, if your EDITOR environment is
 	configured, typing v will immediately open your editor of choice
 	right at the line where the object is defined. Not as quick as
 	having a direct @edit command, but for all intents and purposes it
 	works. And I don't have to worry about writing @edit to deal with
 	all the editors, less does that.
 
 	* Version 0.1.16 released, 0.1.17 opened.
 
 	* Fixed some nasty bugs in the page/page_dumb combo that could
 	crash IPython.
 
 2001-11-27  Fernando Perez  <[e-mail]>
 
 	* Version 0.1.15 released, 0.1.16 opened.
 
 	* Finally got ? and ?? to work for undefined things: now it's
 	possible to type {}.get? and get information about the get method
 	of dicts, or os.path? even if only os is defined (so technically
 	os.path isn't). Works at any level. For example, after import os,
 	os?, os.path?, os.path.abspath? all work. This is great, took some
 	work in _ofind.
 
 	* Fixed more bugs with logging. The sanest way to do it was to add
 	to @log a 'mode' parameter. Killed two in one shot (this mode
 	option was a request of Janko's). I think it's finally clean
 	(famous last words).
 
 	* Added a page_dumb() pager which does a decent job of paging on
 	screen, if better things (like less) aren't available. One less
 	unix dependency (someday maybe somebody will port this to
 	windows).
 
 	* Fixed problem in magic_log: would lock of logging out if log
 	creation failed (because it would still think it had succeeded).
 
 	* Improved the page() function using curses to auto-detect screen
 	size. Now it can make a much better decision on whether to print
 	or page a string. Option screen_length was modified: a value 0
 	means auto-detect, and that's the default now.
 
 	* Version 0.1.14 released, 0.1.15 opened. I think this is ready to
 	go out. I'll test it for a few days, then talk to Janko about
 	licences and announce it.
 
 	* Fixed the length of the auto-generated ---> prompt which appears
 	for auto-parens and auto-quotes. Getting this right isn't trivial,
 	with all the color escapes, different prompt types and optional
 	separators. But it seems to be working in all the combinations.
 
 2001-11-26  Fernando Perez  <[e-mail]>
 
 	* Wrote a regexp filter to get option types from the option names
 	string. This eliminates the need to manually keep two duplicate
 	lists.
 
 	* Removed the unneeded check_option_names. Now options are handled
 	in a much saner manner and it's easy to visually check that things
 	are ok.
 
 	* Updated version numbers on all files I modified to carry a
 	notice so Janko and Nathan have clear version markers.
 
 	* Updated docstring for ultraTB with my changes. I should send
 	this to Nathan.
 
 	* Lots of small fixes. Ran everything through pychecker again.
 
 	* Made loading of deep_reload an cmd line option. If it's not too
 	kosher, now people can just disable it. With -nodeep_reload it's
 	still available as dreload(), it just won't overwrite reload().
 
 	* Moved many options to the no| form (-opt and -noopt
 	accepted). Cleaner.
 
 	* Changed magic_log so that if called with no parameters, it uses
 	'rotate' mode. That way auto-generated logs aren't automatically
 	over-written. For normal logs, now a backup is made if it exists
 	(only 1 level of backups). A new 'backup' mode was added to the
 	Logger class to support this. This was a request by Janko.
 
 	* Added @logoff/@logon to stop/restart an active log.
 
 	* Fixed a lot of bugs in log saving/replay. It was pretty
 	broken. Now special lines (!@,/) appear properly in the command
 	history after a log replay.
 
 	* Tried and failed to implement full session saving via pickle. My
 	idea was to pickle __main__.__dict__, but modules can't be
 	pickled. This would be a better alternative to replaying logs, but
 	seems quite tricky to get to work. Changed -session to be called
 	-logplay, which more accurately reflects what it does. And if we
 	ever get real session saving working, -session is now available.
 
 	* Implemented color schemes for prompts also. As for tracebacks,
 	currently only NoColor and Linux are supported. But now the
 	infrastructure is in place, based on a generic ColorScheme
 	class. So writing and activating new schemes both for the prompts
 	and the tracebacks should be straightforward.
 
 	* Version 0.1.13 released, 0.1.14 opened.
 
 	* Changed handling of options for output cache. Now counter is
 	hardwired starting at 1 and one specifies the maximum number of
 	entries *in the outcache* (not the max prompt counter). This is
 	much better, since many statements won't increase the cache
 	count. It also eliminated some confusing options, now there's only
 	one: cache_size.
 
 	* Added 'alias' magic function and magic_alias option in the
 	ipythonrc file. Now the user can easily define whatever names he
 	wants for the magic functions without having to play weird
 	namespace games. This gives IPython a real shell-like feel.
 
 	* Fixed doc/?/?? for magics. Now all work, in all forms (explicit
 	@ or not).
 
 	This was one of the last remaining 'visible' bugs (that I know
 	of). I think if I can clean up the session loading so it works
 	100% I'll release a 0.2.0 version on c.p.l (talk to Janko first
 	about licensing).	
 
 2001-11-25  Fernando Perez  <[e-mail]>
 
 	* Rewrote somewhat oinfo (?/??). Nicer, now uses page() and
 	there's a cleaner distinction between what ? and ?? show.
 
 	* Added screen_length option. Now the user can define his own
 	screen size for page() operations.
 
 	* Implemented magic shell-like functions with automatic code
 	generation. Now adding another function is just a matter of adding
 	an entry to a dict, and the function is dynamically generated at
 	run-time. Python has some really cool features!
 
 	* Renamed many options to cleanup conventions a little. Now all
 	are lowercase, and only underscores where needed. Also in the code
 	option name tables are clearer.
 
 	* Changed prompts a little. Now input is 'In [n]:' instead of
 	'In[n]:='. This allows it the numbers to be aligned with the
 	Out[n] numbers, and removes usage of ':=' which doesn't exist in
 	Python (it was a Mathematica thing). The '...' continuation prompt
 	was also changed a little to align better.
 
 	* Fixed bug when flushing output cache. Not all _p<n> variables
 	exist, so their deletion needs to be wrapped in a try:
 
 	* Figured out how to properly use inspect.formatargspec() (it
 	requires the args preceded by *). So I removed all the code from
 	_get_pdef in Magic, which was just replicating that.
 
 	* Added test to prefilter to allow redefining magic function names
 	as variables. This is ok, since the @ form is always available,
 	but whe should allow the user to define a variable called 'ls' if
 	he needs it.
 
 	* Moved the ToDo information from README into a separate ToDo.
 
 	* General code cleanup and small bugfixes. I think it's close to a
 	state where it can be released, obviously with a big 'beta'
 	warning on it.
 
 	* Got the magic function split to work. Now all magics are defined
 	in a separate class. It just organizes things a bit, and now
 	Xemacs behaves nicer (it was choking on InteractiveShell b/c it
 	was too long).
 
 	* Changed @clear to @reset to avoid potential confusions with
 	the shell command clear. Also renamed @cl to @clear, which does
 	exactly what people expect it to from their shell experience.
 
 	Added a check to the @reset command (since it's so
 	destructive, it's probably a good idea to ask for confirmation).
 	But now reset only works for full namespace resetting. Since the
 	del keyword is already there for deleting a few specific
 	variables, I don't see the point of having a redundant magic
 	function for the same task.
 
 2001-11-24  Fernando Perez  <[e-mail]>
 
 	* Updated the builtin docs (esp. the ? ones).
 
 	* Ran all the code through pychecker. Not terribly impressed with
 	it: lots of spurious warnings and didn't really find anything of
 	substance (just a few modules being imported and not used).
 
 	* Implemented the new ultraTB functionality into IPython. New
 	option: xcolors. This chooses color scheme. xmode now only selects
 	between Plain and Verbose. Better orthogonality.
 
 	* Large rewrite of ultraTB. Much cleaner now, with a separation of
 	mode and color scheme for the exception handlers. Now it's
 	possible to have the verbose traceback with no coloring.
 
 2001-11-23  Fernando Perez  <[e-mail]>
 
 	* Version 0.1.12 released, 0.1.13 opened.
 
 	* Removed option to set auto-quote and auto-paren escapes by
 	user. The chances of breaking valid syntax are just too high. If
 	someone *really* wants, they can always dig into the code.
 
 	* Made prompt separators configurable.
 
 2001-11-22  Fernando Perez  <[e-mail]>
 
 	* Small bugfixes in many places.
 
 	* Removed the MyCompleter class from ipplib. It seemed redundant
 	with the C-p,C-n history search functionality. Less code to
 	maintain.
 
 	* Moved all the original ipython.py code into ipythonlib.py. Right
 	now it's just one big dump into a function called make_IPython, so
 	no real modularity has been gained. But at least it makes the
 	wrapper script tiny, and since ipythonlib is a module, it gets
 	compiled and startup is much faster.
 
 	This is a reasobably 'deep' change, so we should test it for a
 	while without messing too much more with the code.
 
 2001-11-21  Fernando Perez  <[e-mail]>
 
 	* Version 0.1.11 released, 0.1.12 opened for further work.
 
 	* Removed dependency on Itpl. It was only needed in one place. It
 	would be nice if this became part of python, though. It makes life
 	*a lot* easier in some cases.
 
 	* Simplified the prefilter code a bit. Now all handlers are
 	expected to explicitly return a value (at least a blank string).
 
 	* Heavy edits in ipplib. Removed the help system altogether. Now
 	obj?/?? is used for inspecting objects, a magic @doc prints
 	docstrings, and full-blown Python help is accessed via the 'help'
 	keyword. This cleans up a lot of code (less to maintain) and does
 	the job. Since 'help' is now a standard Python component, might as
 	well use it and remove duplicate functionality.
 
 	Also removed the option to use ipplib as a standalone program. By
 	now it's too dependent on other parts of IPython to function alone.
 
 	* Fixed bug in genutils.pager. It would crash if the pager was
 	exited immediately after opening (broken pipe).
 
 	* Trimmed down the VerboseTB reporting a little. The header is
 	much shorter now and the repeated exception arguments at the end
 	have been removed. For interactive use the old header seemed a bit
 	excessive.
 
 	* Fixed small bug in output of @whos for variables with multi-word
 	types (only first word was displayed).
 
 2001-11-17  Fernando Perez  <[e-mail]>
 
 	* Version 0.1.10 released, 0.1.11 opened for further work.
 
 	* Modified dirs and friends. dirs now *returns* the stack (not
 	prints), so one can manipulate it as a variable. Convenient to
 	travel along many directories.
 
 	* Fixed bug in magic_pdef: would only work with functions with
 	arguments with default values.
 
 2001-11-14  Fernando Perez  <[e-mail]>
 
 	* Added the PhysicsInput stuff to dot_ipython so it ships as an
 	example with IPython. Various other minor fixes and cleanups.
 
 	* Version 0.1.9 released, 0.1.10 opened for further work.
 
 	* Added sys.path to the list of directories searched in the
 	execfile= option. It used to be the current directory and the
 	user's IPYTHONDIR only.
 
 2001-11-13  Fernando Perez  <[e-mail]>
 
 	* Reinstated the raw_input/prefilter separation that Janko had
 	initially. This gives a more convenient setup for extending the
 	pre-processor from the outside: raw_input always gets a string,
 	and prefilter has to process it. We can then redefine prefilter
 	from the outside and implement extensions for special
 	purposes.
 
 	Today I got one for inputting PhysicalQuantity objects
 	(from Scientific) without needing any function calls at
 	all. Extremely convenient, and it's all done as a user-level
 	extension (no IPython code was touched). Now instead of:
 		a = PhysicalQuantity(4.2,'m/s**2')
 	one can simply say
 		a = 4.2 m/s**2
 	or even
 		a = 4.2 m/s^2
 	
 	I use this, but it's also a proof of concept: IPython really is
 	fully user-extensible, even at the level of the parsing of the
 	command line. It's not trivial, but it's perfectly doable.
 
 	* Added 'add_flip' method to inclusion conflict resolver. Fixes
 	the problem of modules being loaded in the inverse order in which
 	they were defined in 
 
 	* Version 0.1.8 released, 0.1.9 opened for further work.
 
 	* Added magics pdef, source and file. They respectively show the
 	definition line ('prototype' in C), source code and full python
 	file for any callable object. The object inspector oinfo uses
 	these to show the same information.
 
 	* Version 0.1.7 released, 0.1.8 opened for further work.
 
 	* Separated all the magic functions into a class called Magic. The
 	InteractiveShell class was becoming too big for Xemacs to handle
 	(de-indenting a line would lock it up for 10 seconds while it
 	backtracked on the whole class!)
 
 	FIXME: didn't work. It can be done, but right now namespaces are
 	all messed up. Do it later (reverted it for now, so at least
 	everything works as before).
 
 	* Got the object introspection system (magic_oinfo) working! I
 	think this is pretty much ready for release to Janko, so he can
 	test it for a while and then announce it. Pretty much 100% of what
 	I wanted for the 'phase 1' release is ready. Happy, tired.
 
 2001-11-12  Fernando Perez  <[e-mail]>
 
 	* Version 0.1.6 released, 0.1.7 opened for further work.
 
 	* Fixed bug in printing: it used to test for truth before
 	printing, so 0 wouldn't print. Now checks for None.
 
 	* Fixed bug where auto-execs increase the prompt counter by 2 (b/c
 	they have to call len(str(sys.ps1)) ). But the fix is ugly, it
 	reaches by hand into the outputcache. Think of a better way to do
 	this later.
 
 	* Various small fixes thanks to Nathan's comments.
 
 	* Changed magic_pprint to magic_Pprint. This way it doesn't
 	collide with pprint() and the name is consistent with the command
 	line option.
 
 	* Changed prompt counter behavior to be fully like
 	Mathematica's. That is, even input that doesn't return a result
 	raises the prompt counter. The old behavior was kind of confusing
 	(getting the same prompt number several times if the operation
 	didn't return a result).
 
 	* Fixed Nathan's last name in a couple of places (Gray, not Graham).
 
 	* Fixed -Classic mode (wasn't working anymore).
 
 	* Added colored prompts using Nathan's new code. Colors are
 	currently hardwired, they can be user-configurable. For
 	developers, they can be chosen in file ipythonlib.py, at the
 	beginning of the CachedOutput class def.
 
 2001-11-11  Fernando Perez  <[e-mail]>
 
 	* Version 0.1.5 released, 0.1.6 opened for further work.
 
 	* Changed magic_env to *return* the environment as a dict (not to
 	print it). This way it prints, but it can also be processed.
 
 	* Added Verbose exception reporting to interactive
 	exceptions. Very nice, now even 1/0 at the prompt gives a verbose
 	traceback. Had to make some changes to the ultraTB file. This is
 	probably the last 'big' thing in my mental todo list.  This ties
 	in with the next entry:
 
 	* Changed -Xi and -Xf to a single -xmode option. Now all the user
 	has to specify is Plain, Color or Verbose for all exception
 	handling.
 
 	* Removed ShellServices option. All this can really be done via
 	the magic system. It's easier to extend, cleaner and has automatic
 	namespace protection and documentation.
 
 2001-11-09  Fernando Perez  <[e-mail]>
 
 	* Fixed bug in output cache flushing (missing parameter to
 	__init__). Other small bugs fixed (found using pychecker).
 
 	* Version 0.1.4 opened for bugfixing.
 
 2001-11-07  Fernando Perez  <[e-mail]>
 
 	* Version 0.1.3 released, mainly because of the raw_input bug.
 
 	* Fixed NASTY bug in raw_input: input line wasn't properly parsed
 	and when testing for whether things were callable, a call could
 	actually be made to certain functions. They would get called again
 	once 'really' executed, with a resulting double call. A disaster
 	in many cases (list.reverse() would never work!).
 
 	* Removed prefilter() function, moved its code to raw_input (which
 	after all was just a near-empty caller for prefilter). This saves
 	a function call on every prompt, and simplifies the class a tiny bit.
 
 	* Fix _ip to __ip name in magic example file.
 
 	* Changed 'tar -x -f' to 'tar xvf' in auto-installer. This should
 	work with non-gnu versions of tar.
 
 2001-11-06  Fernando Perez  <[e-mail]>
 
 	* Version 0.1.2. Just to keep track of the recent changes.
 
 	* Fixed nasty bug in output prompt routine. It used to check 'if
 	arg != None...'. Problem is, this fails if arg implements a
 	special comparison (__cmp__) which disallows comparing to
 	None. Found it when trying to use the PhysicalQuantity module from
 	ScientificPython.
 
 2001-11-05  Fernando Perez  <[e-mail]>
 
 	* Also added dirs. Now the pushd/popd/dirs family functions
 	basically like the shell, with the added convenience of going home
 	when called with no args.
 
 	* pushd/popd slightly modified to mimic shell behavior more
 	closely.
 
 	* Added env,pushd,popd from ShellServices as magic functions. I
 	think the cleanest will be to port all desired functions from
 	ShellServices as magics and remove ShellServices altogether. This
 	will provide a single, clean way of adding functionality
 	(shell-type or otherwise) to IP.
 
 2001-11-04  Fernando Perez  <[e-mail]>
 
 	* Added .ipython/ directory to sys.path. This way users can keep
 	customizations there and access them via import.
 
 2001-11-03  Fernando Perez  <[e-mail]>
 
 	* Opened version 0.1.1 for new changes.
 
 	* Changed version number to 0.1.0: first 'public' release, sent to
 	Nathan and Janko.
 
 	* Lots of small fixes and tweaks.
 
 	* Minor changes to whos format. Now strings are shown, snipped if
 	too long.
 
 	* Changed ShellServices to work on __main__ so they show up in @who
 
 	* Help also works with ? at the end of a line:
 		?sin and sin?
 	both produce the same effect. This is nice, as often I use the
 	tab-complete to find the name of a method, but I used to then have
 	to go to the beginning of the line to put a ? if I wanted more
 	info. Now I can just add the ? and hit return. Convenient.
 
 2001-11-02  Fernando Perez  <[e-mail]>
 
 	* Python version check (>=2.1) added.
 
 	* Added LazyPython documentation. At this point the docs are quite
 	a mess. A cleanup is in order.
 
 	* Auto-installer created. For some bizarre reason, the zipfiles
 	module isn't working on my system. So I made a tar version
 	(hopefully the command line options in various systems won't kill
 	me).
 
 	* Fixes to Struct in genutils. Now all dictionary-like methods are
 	protected (reasonably).
 
 	* Added pager function to genutils and changed ? to print usage
 	note through it (it was too long).
 
 	* Added the LazyPython functionality. Works great! I changed the
 	auto-quote escape to ';', it's on home row and next to '. But
 	both auto-quote and auto-paren (still /) escapes are command-line
 	parameters.
 	
 
 2001-11-01  Fernando Perez  <[e-mail]>
 
 	* Version changed to 0.0.7. Fairly large change: configuration now
 	is all stored in a directory, by default .ipython. There, all
 	config files have normal looking names (not .names)
 
 	* Version 0.0.6 Released first to Lucas and Archie as a test
 	run. Since it's the first 'semi-public' release, change version to
 	> 0.0.6 for any changes now.
 
 	* Stuff I had put in the ipplib.py changelog:
 	
 	Changes to InteractiveShell:
 	
 	- Made the usage message a parameter.
 	
 	- Require the name of the shell variable to be given. It's a bit
 	of a hack, but allows the name 'shell' not to be hardwired in the
 	magic (@) handler, which is problematic b/c it requires
 	polluting the global namespace with 'shell'. This in turn is
 	fragile: if a user redefines a variable called shell, things
 	break.
 
 	- magic @: all functions available through @ need to be defined
 	as magic_<name>, even though they can be called simply as
 	@<name>. This allows the special command @magic to gather
 	information automatically about all existing magic functions,
 	even if they are run-time user extensions, by parsing the shell
 	instance __dict__ looking for special magic_ names.
 
 	- mainloop: added *two* local namespace parameters. This allows
 	the class to differentiate between parameters which were there
 	before and after command line initialization was processed. This
 	way, later @who can show things loaded at startup by the
 	user. This trick was necessary to make session saving/reloading
 	really work: ideally after saving/exiting/reloading a session,
 	*everything* should look the same, including the output of @who. I
 	was only able to make this work with this double namespace
 	trick.
 
 	- added a header to the logfile which allows (almost) full
 	session restoring.
 
 	- prepend lines beginning with @ or !, with a and log
 	them. Why?  !lines: may be useful to know what you did @lines:
 	they may affect session state. So when restoring a session, at
 	least inform the user of their presence. I couldn't quite get
 	them to properly re-execute, but at least the user is warned.
 
 	* Started ChangeLog.

 .SH NAME
 ipython \- An Enhanced Interactive Python
 .SH SYNOPSIS
 .B ipython
 .RI [ options ] " files" ...
 .SH DESCRIPTION
 An interactive Python shell with automatic history (input and output),
 dynamic object introspection, easier configuration, command
 completion, access to the system shell, integration with numerical and
 scientific computing tools, and more.
 .SH SPECIAL THREADING OPTIONS
 The following special options are ONLY valid at the beginning of the command
 line, and not later.  This is because they control the initialization of
 ipython itself, before the normal option-handling mechanism is active.
 .TP
-.B \-gthread, \-qthread, \-q4thread, \-wthread, \-pylab, \-twisted
+.B \-gthread, \-qthread, \-q4thread, \-wthread, \-pylab
 Only ONE of these can be given, and it can only be given as the first option
 passed to IPython (it will have no effect in any other position).  They provide
 threading support for the GTK, QT3, QT4 and WXWidgets toolkits, for the
 matplotlib library and Twisted reactor.
 .br
 .sp 1
 With any of the first four options, IPython starts running a separate thread
 for the graphical toolkit's operation, so that you can open and control
 graphical elements from within an IPython command line, without blocking.  All
 four provide essentially the same functionality, respectively for GTK, QT3, QT4
 and WXWidgets (via their Python interfaces).
 .br
 .sp 1
 Note that with \-wthread, you can additionally use the \-wxversion option to
 request a specific version of wx to be used.  This requires that you have the
 'wxversion' Python module installed, which is part of recent wxPython
 distributions.
 .br
 .sp 1
-If \-twisted is given, IPython start a Twisted reactor and runs IPython mainloop
-in a dedicated thread, passing commands to be run inside the Twisted reactor. 
-.br
-.sp 1
 If \-pylab is given, IPython loads special support for the matplotlib library
 (http://matplotlib.sourceforge.net), allowing interactive usage of any of its
 backends as defined in the user's .matplotlibrc file.  It automatically
 activates GTK, QT or WX threading for IPyhton if the choice of matplotlib
 backend requires it.  It also modifies the %run command to correctly execute
 (without blocking) any matplotlib-based script which calls show() at the end.
 .TP
 .B \-tk
 The \-g/q/q4/wthread options, and \-pylab (if matplotlib is configured to use
 GTK, QT or WX), will normally block Tk graphical interfaces.  This means that
 when GTK, QT or WX threading is active, any attempt to open a Tk GUI will
 result in a dead window, and possibly cause the Python interpreter to crash.
 An extra option, \-tk, is available to address this issue.  It can ONLY be
 given as a SECOND option after any of the above (\-gthread, \-qthread,
 \-wthread or \-pylab).
 .br
 .sp 1
 If \-tk is given, IPython will try to coordinate Tk threading with GTK, QT or
 WX.  This is however potentially unreliable, and you will have to test on your
 platform and Python configuration to determine whether it works for you.
 Debian users have reported success, apparently due to the fact that Debian
 builds all of Tcl, Tk, Tkinter and Python with pthreads support.  Under other
 Linux environments (such as Fedora Core 2), this option has caused random
 crashes and lockups of the Python interpreter.  Under other operating systems
 (Mac OSX and Windows), you'll need to try it to find out, since currently no
 user reports are available.
 .br
 .sp 1
 There is unfortunately no way for IPython to determine at runtime whether \-tk
 will work reliably or not, so you will need to do some experiments before
 relying on it for regular work.
 .
 .SH REGULAR OPTIONS
 After the above threading options have been given, regular options can follow
 in any order.  All options can be abbreviated to their shortest non-ambiguous
 form and are case-sensitive.  One or two dashes can be used.  Some options
 have an alternate short form, indicated after a |.
 .br
 .sp 1
 Most options can also be set from your ipythonrc configuration file.
 See the provided examples for assistance.  Options given on the
 commandline override the values set in the ipythonrc file.
 .br
 .sp 1
 All options with a [no] prepended can be specified in negated form
 (\-nooption instead of \-option) to turn the feature off.
 .TP
 .B \-h, \-\-help
 Show summary of options.
 .TP
 .B \-autocall <val>
 Make IPython automatically call any callable object even if you didn't type
 explicit parentheses. For example, 'str 43' becomes
 'str(43)' automatically.  The value can be '0' to disable the
 feature, '1' for 'smart' autocall, where it is not applied if
 there are no more arguments on the line, and '2' for 'full'
 autocall, where all callable objects are automatically called
 (even if no arguments are present).  The default is '1'.
 .TP
 .B \-[no]autoindent
 Turn automatic indentation on/off.
 .TP
 .B \-[no]automagic
 Make magic commands automatic (without needing their first character
 to be %).  Type %magic at the IPython prompt for more information.
 .TP
 .B \-[no]autoedit_syntax
 When a syntax error occurs after editing a file, automatically open the file
 to the trouble causing line for convenient fixing.
 .TP
 .B \-[no]banner
 Print the intial information banner (default on).
 .TP
 .B \-c <command>
 Execute the given command string, and set sys.argv to ['c'].  This is similar
 to the \-c option in the normal Python interpreter.
 .TP
 .B \-cache_size|cs <n>
 Size of the output cache (maximum number of entries to hold in
 memory).  The default is 1000, you can change it permanently in your
 config file.  Setting it to 0 completely disables the caching system,
 and the minimum value accepted is 20 (if you provide a value less than
 20, it is reset to 0 and a warning is issued).  This limit is defined
 because otherwise you'll spend more time re-flushing a too small cache
 than working.
 .TP
 .B \-classic|cl
 Gives IPython a similar feel to the classic Python prompt.
 .TP
 .B \-colors <scheme>
 Color scheme for prompts and exception reporting.  Currently
 implemented: NoColor, Linux, and LightBG.
 .TP
 .B \-[no]color_info
 IPython can display information about objects via a set of functions,
 and optionally can use colors for this, syntax highlighting source
 code and various other elements.  However, because this information is
 passed through a pager (like 'less') and many pagers get confused with
 color codes, this option is off by default.  You can test it and turn
 it on permanently in your ipythonrc file if it works for you.  As a
 reference, the 'less' pager supplied with Mandrake 8.2 works ok, but
 that in RedHat 7.2 doesn't.
 .br
 .sp 1
 Test it and turn it on permanently if it works with your system.  The
 magic function @color_info allows you to toggle this interactively for
 testing.
 .TP
 .B \-[no]confirm_exit
 Set to confirm when you try to exit IPython with an EOF (Control-D in
 Unix, Control-Z/Enter in Windows). Note that using the magic functions
 @Exit or @Quit you can force a direct exit, bypassing any
 confirmation.
 .TP
 .B \-[no]debug
 Show information about the loading process. Very useful to pin down
 problems with your configuration files or to get details about session
 restores.
 .TP
 .B \-[no]deep_reload
 IPython can use the deep_reload module which reloads changes in
 modules recursively (it replaces the reload() function, so you don't
 need to change anything to use it). deep_reload() forces a full reload
 of modules whose code may have changed, which the default reload()
 function does not.
 .br
 .sp 1
 When deep_reload is off, IPython will use the normal reload(), but
 deep_reload will still be available as dreload(). This feature is off
 by default [which means that you have both normal reload() and
 dreload()].
 .TP
 .B \-editor <name>
 Which editor to use with the @edit command. By default, IPython will
 honor your EDITOR environment variable (if not set, vi is the Unix
 default and notepad the Windows one). Since this editor is invoked on
 the fly by IPython and is meant for editing small code snippets, you
 may want to use a small, lightweight editor here (in case your default
 EDITOR is something like Emacs).
 .TP
 .B \-ipythondir <name>
 The name of your IPython configuration directory IPYTHONDIR.  This can
 also be specified through the environment variable IPYTHONDIR.
 .TP
 .B \-log|l
 Generate a log file of all input. The file is named ipython_log.py in your
 current directory (which prevents logs from multiple IPython sessions from
 trampling each other). You can use this to later restore a session by loading
 your logfile as a file to be executed with option -logplay (see below).
 .TP
 .B \-logfile|lf
 Specify the name of your logfile.
 .TP
 .B \-logplay|lp
 Replay a previous log. For restoring a session as close as possible to
 the state you left it in, use this option (don't just run the
 logfile). With \-logplay, IPython will try to reconstruct the previous
 working environment in full, not just execute the commands in the
 logfile.
 .br
 .sh 1
 When a session is restored, logging is automatically turned on again
 with the name of the logfile it was invoked with (it is read from the
 log header). So once you've turned logging on for a session, you can
 quit IPython and reload it as many times as you want and it will
 continue to log its history and restore from the beginning every time.
 .br
 .sp 1
 Caveats: there are limitations in this option. The history variables
 _i*,_* and _dh don't get restored properly. In the future we will try
 to implement full session saving by writing and retrieving a
 'snapshot' of the memory state of IPython. But our first attempts
 failed because of inherent limitations of Python's Pickle module, so
 this may have to wait.
 .TP
 .B \-[no]messages
 Print messages which IPython collects about its startup process
 (default on).
 .TP
 .B \-[no]pdb
 Automatically call the pdb debugger after every uncaught exception. If
 you are used to debugging using pdb, this puts you automatically
 inside of it after any call (either in IPython or in code called by
 it) which triggers an exception which goes uncaught.
 .TP
+.B \-pydb
+Makes IPython use the third party "pydb" package as debugger,
+instead of pdb. Requires that pydb is installed.
+.TP
 .B \-[no]pprint
 IPython can optionally use the pprint (pretty printer) module for
 displaying results. pprint tends to give a nicer display of nested
 data structures. If you like it, you can turn it on permanently in
 your config file (default off).
 .TP
 .B \-profile|p <name>
 Assume that your config file is ipythonrc-<name> (looks in current dir
 first, then in IPYTHONDIR). This is a quick way to keep and load
 multiple config files for different tasks, especially if you use the
 include option of config files. You can keep a basic
 IPYTHONDIR/ipythonrc file and then have other 'profiles' which include
 this one and load extra things for particular tasks. For example:
 .br
 .sp 1
 1) $HOME/.ipython/ipythonrc : load basic things you always want.
 .br
 2) $HOME/.ipython/ipythonrc-math : load (1) and basic math-related
 modules.
 .br
 3) $HOME/.ipython/ipythonrc-numeric : load (1) and Numeric and
 plotting modules.
 .br
 .sp 1
 Since it is possible to create an endless loop by having circular file
 inclusions, IPython will stop if it reaches 15 recursive inclusions.
 .TP
 .B \-prompt_in1|pi1 <string>
 Specify the string used for input prompts. Note that if you are using
 numbered prompts, the number is represented with a '\\#' in the
 string. Don't forget to quote strings with spaces embedded in
 them. Default: 'In [\\#]: '.
 .br
 .sp 1
 Most bash-like escapes can be used to customize IPython's prompts, as well as
 a few additional ones which are IPython-specific.  All valid prompt escapes
 are described in detail in the Customization section of the IPython HTML/PDF
 manual.
 .TP
 .B \-prompt_in2|pi2 <string>
 Similar to the previous option, but used for the continuation prompts. The
 special sequence '\\D' is similar to '\\#', but with all digits replaced dots
 (so you can have your continuation prompt aligned with your input
 prompt). Default: '   .\\D.: ' (note three spaces at the start for alignment
 with 'In [\\#]').
 .TP
 .B \-prompt_out|po <string>
 String used for output prompts, also uses numbers like prompt_in1.
 Default: 'Out[\\#]:'.
 .TP
 .B \-quick
 Start in bare bones mode (no config file loaded).
 .TP
 .B \-rcfile <name>
 Name of your IPython resource configuration file.  normally IPython
 loads ipythonrc (from current directory) or IPYTHONDIR/ipythonrc.  If
 the loading of your config file fails, IPython starts with a bare
 bones configuration (no modules loaded at all).
 .TP
 .B \-[no]readline
 Use the readline library, which is needed to support name completion
 and command history, among other things. It is enabled by default, but
 may cause problems for users of X/Emacs in Python comint or shell
 buffers.
 .br
 .sp 1
 Note that emacs 'eterm' buffers (opened with M-x term) support
 IPython's readline and syntax coloring fine, only 'emacs' (M-x shell
 and C-c !)  buffers do not.
 .TP
 .B \-screen_length|sl <n>
 Number of lines of your screen.  This is used to control printing of
 very long strings.  Strings longer than this number of lines will be
 sent through a pager instead of directly printed.
 .br
 .sp 1
 The default value for this is 0, which means IPython will auto-detect
 your screen size every time it needs to print certain potentially long
 strings (this doesn't change the behavior of the 'print' keyword, it's
 only triggered internally). If for some reason this isn't working well
 (it needs curses support), specify it yourself. Otherwise don't change
 the default.
 .TP
 .B \-separate_in|si <string>
 Separator before input prompts.  Default '\n'.
 .TP
 .B \-separate_out|so <string>
 Separator before output prompts.  Default: 0 (nothing).
 .TP
 .B \-separate_out2|so2 <string>
 Separator after output prompts.  Default: 0 (nothing).
 .TP
 .B \-nosep
 Shorthand for '\-separate_in 0 \-separate_out 0 \-separate_out2 0'.
 Simply removes all input/output separators.
 .TP
 .B \-upgrade
 Allows you to upgrade your IPYTHONDIR configuration when you install a
 new version of IPython.  Since new versions may include new command
 lines options or example files, this copies updated ipythonrc-type
 files.  However, it backs up (with a .old extension) all files which
 it overwrites so that you can merge back any custimizations you might
 have in your personal files.
 .TP
 .B \-Version
 Print version information and exit.
 .TP
 .B -wxversion <string>
 Select a specific version of wxPython (used in conjunction with
 \-wthread). Requires the wxversion module, part of recent wxPython
 distributions.
 .TP
 .B \-xmode <modename>
 Mode for exception reporting.  The valid modes are Plain, Context, and
 Verbose.
 .br
 .sp 1
 \- Plain: similar to python's normal traceback printing.
 .br
 .sp 1
 \- Context: prints 5 lines of context source code around each line in the
 traceback.
 .br
 .sp 1
 \- Verbose: similar to Context, but additionally prints the variables
 currently visible where the exception happened (shortening their strings if
 too long).  This can potentially be very slow, if you happen to have a huge
 data structure whose string representation is complex to compute.  Your
 computer may appear to freeze for a while with cpu usage at 100%.  If this
 occurs, you can cancel the traceback with Ctrl-C (maybe hitting it more than
 once).
 .
 .SH EMBEDDING
 It is possible to start an IPython instance inside your own Python
 programs.  In the documentation example files there are some
 illustrations on how to do this.
 .br
 .sp 1
 This feature allows you to evalutate dynamically the state of your
 code, operate with your variables, analyze them, etc.  Note however
 that any changes you make to values while in the shell do NOT
 propagate back to the running code, so it is safe to modify your
 values because you won't break your code in bizarre ways by doing so.

 Introduction
 ============
 
 This is the official documentation for IPython 0.x series (i.e. what
 we are used to refer to just as "IPython"). The original text of the
 manual (most of which is still in place) has been authored by Fernando
 Perez, but as recommended usage patterns and new features have
 emerged, this manual has been updated to reflect that fact. Most of
 the additions have been authored by Ville M. Vainio.
 
 The manual has been generated from reStructuredText source markup with
 Sphinx, which should make it much easier to keep it up-to-date in the
 future. Some reST artifacts and bugs may still be apparent in the
 documentation, but this should improve as the toolchain matures.
 
 Overview
 ========
 
 One of Python's most useful features is its interactive interpreter.
 This system allows very fast testing of ideas without the overhead of
 creating test files as is typical in most programming languages.
 However, the interpreter supplied with the standard Python distribution
 is somewhat limited for extended interactive use.
 
 IPython is a free software project (released under the BSD license)
 which tries to:
 
    1. Provide an interactive shell superior to Python's default. IPython
       has many features for object introspection, system shell access,
       and its own special command system for adding functionality when
       working interactively. It tries to be a very efficient environment
       both for Python code development and for exploration of problems
       using Python objects (in situations like data analysis).
    2. Serve as an embeddable, ready to use interpreter for your own
       programs. IPython can be started with a single call from inside
       another program, providing access to the current namespace. This
       can be very useful both for debugging purposes and for situations
       where a blend of batch-processing and interactive exploration are
       needed.
    3. Offer a flexible framework which can be used as the base
       environment for other systems with Python as the underlying
       language. Specifically scientific environments like Mathematica,
       IDL and Matlab inspired its design, but similar ideas can be
       useful in many fields.
    4. Allow interactive testing of threaded graphical toolkits. IPython
       has support for interactive, non-blocking control of GTK, Qt and
       WX applications via special threading flags. The normal Python
       shell can only do this for Tkinter applications.
 
 
 Main features
 -------------
 
 * Dynamic object introspection. One can access docstrings, function
   definition prototypes, source code, source files and other details
   of any object accessible to the interpreter with a single
   keystroke ('?', and using '??' provides additional detail).
 * Searching through modules and namespaces with '*' wildcards, both
   when using the '?' system and via the %psearch command.
 * Completion in the local namespace, by typing TAB at the prompt.
   This works for keywords, modules, methods, variables and files in the
   current directory. This is supported via the readline library, and
   full access to configuring readline's behavior is provided. 
   Custom completers can be implemented easily for different purposes
   (system commands, magic arguments etc.)
 * Numbered input/output prompts with command history (persistent
   across sessions and tied to each profile), full searching in this
   history and caching of all input and output.
 * User-extensible 'magic' commands. A set of commands prefixed with
   % is available for controlling IPython itself and provides
   directory control, namespace information and many aliases to
   common system shell commands.
 * Alias facility for defining your own system aliases.
 * Complete system shell access. Lines starting with ! are passed
   directly to the system shell, and using !! or var = !cmd 
   captures shell output into python variables for further use.
 * Background execution of Python commands in a separate thread.
   IPython has an internal job manager called jobs, and a
   conveninence backgrounding magic function called %bg.
 * The ability to expand python variables when calling the system
   shell. In a shell command, any python variable prefixed with $ is
   expanded. A double $$ allows passing a literal $ to the shell (for
   access to shell and environment variables like $PATH).
 * Filesystem navigation, via a magic %cd command, along with a
   persistent bookmark system (using %bookmark) for fast access to
   frequently visited directories.
 * A lightweight persistence framework via the %store command, which
   allows you to save arbitrary Python variables. These get restored
   automatically when your session restarts.
 * Automatic indentation (optional) of code as you type (through the
   readline library).
 * Macro system for quickly re-executing multiple lines of previous
   input with a single name. Macros can be stored persistently via
   %store and edited via %edit.
 * Session logging (you can then later use these logs as code in your
   programs). Logs can optionally timestamp all input, and also store
   session output (marked as comments, so the log remains valid
   Python source code).
 * Session restoring: logs can be replayed to restore a previous
   session to the state where you left it.
 * Verbose and colored exception traceback printouts. Easier to parse
   visually, and in verbose mode they produce a lot of useful
   debugging information (basically a terminal version of the cgitb
   module).
 * Auto-parentheses: callable objects can be executed without
   parentheses: 'sin 3' is automatically converted to 'sin(3)'.
 * Auto-quoting: using ',' or ';' as the first character forces
   auto-quoting of the rest of the line: ',my_function a b' becomes
   automatically 'my_function("a","b")', while ';my_function a b'
   becomes 'my_function("a b")'.
 * Extensible input syntax. You can define filters that pre-process
   user input to simplify input in special situations. This allows
   for example pasting multi-line code fragments which start with
   '>>>' or '...' such as those from other python sessions or the
   standard Python documentation.
 * Flexible configuration system. It uses a configuration file which
   allows permanent setting of all command-line options, module
   loading, code and file execution. The system allows recursive file
   inclusion, so you can have a base file with defaults and layers
   which load other customizations for particular projects.
 * Embeddable. You can call IPython as a python shell inside your own
   python programs. This can be used both for debugging code or for
   providing interactive abilities to your programs with knowledge
   about the local namespaces (very useful in debugging and data
   analysis situations).
 * Easy debugger access. You can set IPython to call up an enhanced
   version of the Python debugger (pdb) every time there is an
   uncaught exception. This drops you inside the code which triggered
   the exception with all the data live and it is possible to
   navigate the stack to rapidly isolate the source of a bug. The
   %run magic command -with the -d option- can run any script under
   pdb's control, automatically setting initial breakpoints for you.
   This version of pdb has IPython-specific improvements, including
   tab-completion and traceback coloring support. For even easier
   debugger access, try %debug after seeing an exception. winpdb is 
   also supported, see ipy_winpdb extension.
 * Profiler support. You can run single statements (similar to
   profile.run()) or complete programs under the profiler's control.
   While this is possible with standard cProfile or profile modules,
   IPython wraps this functionality with magic commands (see '%prun'
   and '%run -p') convenient for rapid interactive work.
 * Doctest support. The special %doctest_mode command toggles a mode
   that allows you to paste existing doctests (with leading '>>>'
   prompts and whitespace) and uses doctest-compatible prompts and
   output, so you can use IPython sessions as doctest code.
 
 
 Portability and Python requirements
 -----------------------------------
 
 Python requirements: IPython requires with Python version 2.3 or newer.
 If you are still using Python 2.2 and can not upgrade, the last version
 of IPython which worked with Python 2.2 was 0.6.15, so you will have to
 use that.
 
 IPython is developed under Linux, but it should work in any reasonable
 Unix-type system (tested OK under Solaris and the BSD family, for which
 a port exists thanks to Dryice Liu).
 
 Mac OS X: it works, apparently without any problems (thanks to Jim Boyle
 at Lawrence Livermore for the information). Thanks to Andrea Riciputi,
 Fink support is available.
 
 CygWin: it works mostly OK, though some users have reported problems
 with prompt coloring. No satisfactory solution to this has been found so
 far, you may want to disable colors permanently in the ipythonrc
 configuration file if you experience problems. If you have proper color
 support under cygwin, please post to the IPython mailing list so this
 issue can be resolved for all users.
 
 Windows: it works well under Windows Vista/XP/2k, and I suspect NT should
 behave similarly. Section "Installation under windows" describes
 installation details for Windows, including some additional tools needed
 on this platform.
 
 Windows 9x support is present, and has been reported to work fine (at
 least on WinME).
 
 Location
 --------
 
 IPython is generously hosted at http://ipython.scipy.org by the
 Enthought, Inc and the SciPy project. This site offers downloads,
 subversion access, mailing lists and a bug tracking system. I am very
 grateful to Enthought (http://www.enthought.com) and all of the SciPy
 team for their contribution.
 
 Installation
 ============
 
 Instant instructions
 --------------------
 
 If you are of the impatient kind, under Linux/Unix simply untar/unzip
 the download, then install with 'python setup.py install'. Under
 Windows, double-click on the provided .exe binary installer.
 
 Then, take a look at Customization_ section for configuring things
 optimally and `Quick tips`_ for quick tips on efficient use of
 IPython. You can later refer to the rest of the manual for all the
 gory details.
 
 See the notes in upgrading_ section for upgrading IPython versions.
 
 
     Detailed Unix instructions (Linux, Mac OS X, etc.)
 
 For RPM based systems, simply install the supplied package in the usual
 manner. If you download the tar archive, the process is:
 
    1. Unzip/untar the ipython-XXX.tar.gz file wherever you want (XXX is
       the version number). It will make a directory called ipython-XXX.
       Change into that directory where you will find the files README
       and setup.py. Once you've completed the installation, you can
       safely remove this directory.
    2. If you are installing over a previous installation of version
       0.2.0 or earlier, first remove your $HOME/.ipython directory,
       since the configuration file format has changed somewhat (the '='
       were removed from all option specifications). Or you can call
       ipython with the -upgrade option and it will do this automatically
       for you.
    3. IPython uses distutils, so you can install it by simply typing at
       the system prompt (don't type the $)::
       
       	$ python setup.py install
       	
       Note that this assumes you have root access to your machine. If
       you don't have root access or don't want IPython to go in the
       default python directories, you'll need to use the ``--home`` option
       (or ``--prefix``). For example::
       
       	$ python setup.py install --home $HOME/local
       	
       will install IPython into $HOME/local and its subdirectories
       (creating them if necessary).
       You can type::
       
       	$ python setup.py --help
       	
       for more details.
       
       Note that if you change the default location for ``--home`` at
       installation, IPython may end up installed at a location which is
       not part of your $PYTHONPATH environment variable. In this case,
       you'll need to configure this variable to include the actual
       directory where the IPython/ directory ended (typically the value
       you give to ``--home`` plus /lib/python).
 
 
 Mac OSX information
 -------------------
 
 Under OSX, there is a choice you need to make. Apple ships its own build
 of Python, which lives in the core OSX filesystem hierarchy. You can
 also manually install a separate Python, either purely by hand
 (typically in /usr/local) or by using Fink, which puts everything under
 /sw. Which route to follow is a matter of personal preference, as I've
 seen users who favor each of the approaches. Here I will simply list the
 known installation issues under OSX, along with their solutions.
 
 This page: http://geosci.uchicago.edu/~tobis/pylab.html contains
 information on this topic, with additional details on how to make
 IPython and matplotlib play nicely under OSX.
 
 To run IPython and readline on OSX "Leopard" system python, see the 
 wiki page at http://ipython.scipy.org/moin/InstallationOSXLeopard
 
 
 GUI problems
 ------------
 
 The following instructions apply to an install of IPython under OSX from
 unpacking the .tar.gz distribution and installing it for the default
 Python interpreter shipped by Apple. If you are using a fink install,
 fink will take care of these details for you, by installing IPython
 against fink's Python.
 
 IPython offers various forms of support for interacting with graphical
 applications from the command line, from simple Tk apps (which are in
 principle always supported by Python) to interactive control of WX, Qt
 and GTK apps. Under OSX, however, this requires that ipython is
 installed by calling the special pythonw script at installation time,
 which takes care of coordinating things with Apple's graphical environment.
 
 So when installing under OSX, it is best to use the following command:: 
 
 	$ sudo pythonw setup.py install --install-scripts=/usr/local/bin
 
 or
 
 	$ sudo pythonw setup.py install --install-scripts=/usr/bin
 	
 depending on where you like to keep hand-installed executables.
 
 The resulting script will have an appropriate shebang line (the first
 line in the script whic begins with #!...) such that the ipython
 interpreter can interact with the OS X GUI. If the installed version
 does not work and has a shebang line that points to, for example, just
 /usr/bin/python, then you might have a stale, cached version in your
 build/scripts-<python-version> directory. Delete that directory and
 rerun the setup.py.
 
 It is also a good idea to use the special flag ``--install-scripts`` as
 indicated above, to ensure that the ipython scripts end up in a location
 which is part of your $PATH. Otherwise Apple's Python will put the
 scripts in an internal directory not available by default at the command
 line (if you use /usr/local/bin, you need to make sure this is in your
 $PATH, which may not be true by default).
 
 
 Readline problems
 -----------------
 
 By default, the Python version shipped by Apple does not include the
 readline library, so central to IPython's behavior. If you install
 IPython against Apple's Python, you will not have arrow keys, tab
 completion, etc. For Mac OSX 10.3 (Panther), you can find a prebuilt
 readline library here:
 http://pythonmac.org/packages/readline-5.0-py2.3-macosx10.3.zip
 
 If you are using OSX 10.4 (Tiger), after installing this package you
 need to either:
 
    1. move readline.so from /Library/Python/2.3 to
       /Library/Python/2.3/site-packages, or
    2. install http://pythonmac.org/packages/TigerPython23Compat.pkg.zip
 
 Users installing against Fink's Python or a properly hand-built one
 should not have this problem.
 
 
 DarwinPorts
 -----------
 
 I report here a message from an OSX user, who suggests an alternative
 means of using IPython under this operating system with good results.
 Please let me know of any updates that may be useful for this section.
 His message is reproduced verbatim below:
 
     From: Markus Banfi <markus.banfi-AT-mospheira.net> 
 
     As a MacOS X (10.4.2) user I prefer to install software using
     DawinPorts instead of Fink. I had no problems installing ipython
     with DarwinPorts. It's just: 
 
     sudo port install py-ipython 
 
     It automatically resolved all dependencies (python24, readline,
     py-readline). So far I did not encounter any problems with the
     DarwinPorts port of ipython. 
 
 
 
 Windows instructions
 --------------------
 
 Some of IPython's very useful features are:
 
     * Integrated readline support (Tab-based file, object and attribute
       completion, input history across sessions, editable command line,
       etc.)
     * Coloring of prompts, code and tracebacks.
 
 .. _pyreadline:
 
 These, by default, are only available under Unix-like operating systems.
 However, thanks to Gary Bishop's work, Windows XP/2k users can also
 benefit from them. His readline library originally implemented both GNU
 readline functionality and color support, so that IPython under Windows
 XP/2k can be as friendly and powerful as under Unix-like environments.
 
 This library, now named PyReadline, has been absorbed by the IPython
 team (Jörgen Stenarson, in particular), and it continues to be developed
 with new features, as well as being distributed directly from the
 IPython site.
 
 The PyReadline extension requires CTypes and the windows IPython
 installer needs PyWin32, so in all you need:
 
    1. PyWin32 from http://sourceforge.net/projects/pywin32.
    2. PyReadline for Windows from
       http://ipython.scipy.org/moin/PyReadline/Intro. That page contains
       further details on using and configuring the system to your liking.
    3. Finally, only if you are using Python 2.3 or 2.4, you need CTypes
       from http://starship.python.net/crew/theller/ctypes(you must use
       version 0.9.1 or newer). This package is included in Python 2.5,
       so you don't need to manually get it if your Python version is 2.5
       or newer.
 
 Warning about a broken readline-like library: several users have
 reported problems stemming from using the pseudo-readline library at
 http://newcenturycomputers.net/projects/readline.html. This is a broken
 library which, while called readline, only implements an incomplete
 subset of the readline API. Since it is still called readline, it fools
 IPython's detection mechanisms and causes unpredictable crashes later.
 If you wish to use IPython under Windows, you must NOT use this library,
 which for all purposes is (at least as of version 1.6) terminally broken.
 
 
 Installation procedure
 ----------------------
 
 Once you have the above installed, from the IPython download directory
 grab the ipython-XXX.win32.exe file, where XXX represents the version
 number. This is a regular windows executable installer, which you can
 simply double-click to install. It will add an entry for IPython to your
 Start Menu, as well as registering IPython in the Windows list of
 applications, so you can later uninstall it from the Control Panel.
 
 IPython tries to install the configuration information in a directory
 named .ipython (_ipython under Windows) located in your 'home'
 directory. IPython sets this directory by looking for a HOME environment
 variable; if such a variable does not exist, it uses HOMEDRIVE\HOMEPATH
 (these are always defined by Windows). This typically gives something
 like C:\Documents and Settings\YourUserName, but your local details may
 vary. In this directory you will find all the files that configure
 IPython's defaults, and you can put there your profiles and extensions.
 This directory is automatically added by IPython to sys.path, so
 anything you place there can be found by import statements.
 
 
 Upgrading
 ---------
 
 For an IPython upgrade, you should first uninstall the previous version.
 This will ensure that all files and directories (such as the
 documentation) which carry embedded version strings in their names are
 properly removed.
 
 
 Manual installation under Win32
 -------------------------------
 
 In case the automatic installer does not work for some reason, you can
 download the ipython-XXX.tar.gz file, which contains the full IPython
 source distribution (the popular WinZip can read .tar.gz files). After
 uncompressing the archive, you can install it at a command terminal just
 like any other Python module, by using 'python setup.py install'.
 
 After the installation, run the supplied win32_manual_post_install.py
 script, which creates the necessary Start Menu shortcuts for you.
 
 
 .. upgrading:
 
 Upgrading from a previous version
 ---------------------------------
 
 If you are upgrading from a previous version of IPython, you may want
 to upgrade the contents of your ~/.ipython directory. Just run
 %upgrade, look at the diffs and delete the suggested files manually,
 if you think you can lose the old versions. %upgrade will never
 overwrite or delete anything.
 
 Initial configuration of your environment
 =========================================
 
 This section will help you set various things in your environment for
 your IPython sessions to be as efficient as possible. All of IPython's
 configuration information, along with several example files, is stored
 in a directory named by default $HOME/.ipython. You can change this by
 defining the environment variable IPYTHONDIR, or at runtime with the
 command line option -ipythondir.
 
 If all goes well, the first time you run IPython it should
 automatically create a user copy of the config directory for you,
 based on its builtin defaults. You can look at the files it creates to
 learn more about configuring the system. The main file you will modify
 to configure IPython's behavior is called ipythonrc (with a .ini
 extension under Windows), included for reference in `ipythonrc`_ 
 section. This file is very commented and has many variables you can
 change to suit your taste, you can find more details in
 Sec. customization_. Here we discuss the basic things you will want to
 make sure things are working properly from the beginning.
 
 
 .. _Accessing help:
 
 Access to the Python help system
 --------------------------------
 
 This is true for Python in general (not just for IPython): you should
 have an environment variable called PYTHONDOCS pointing to the directory
 where your HTML Python documentation lives. In my system it's
 /usr/share/doc/python-docs-2.3.4/html, check your local details or ask
 your systems administrator.
 
 This is the directory which holds the HTML version of the Python
 manuals. Unfortunately it seems that different Linux distributions
 package these files differently, so you may have to look around a bit.
 Below I show the contents of this directory on my system for reference::
 
     [html]> ls 
     about.dat acks.html dist/ ext/ index.html lib/ modindex.html
     stdabout.dat tut/ about.html api/ doc/ icons/ inst/ mac/ ref/ style.css
 
 You should really make sure this variable is correctly set so that
 Python's pydoc-based help system works. It is a powerful and convenient
 system with full access to the Python manuals and all modules accessible
 to you.
 
 Under Windows it seems that pydoc finds the documentation automatically,
 so no extra setup appears necessary.
 
 
 Editor
 ------
 
 The %edit command (and its alias %ed) will invoke the editor set in your
 environment as EDITOR. If this variable is not set, it will default to
 vi under Linux/Unix and to notepad under Windows. You may want to set
 this variable properly and to a lightweight editor which doesn't take
 too long to start (that is, something other than a new instance of
 Emacs). This way you can edit multi-line code quickly and with the power
 of a real editor right inside IPython.
 
 If you are a dedicated Emacs user, you should set up the Emacs server so
 that new requests are handled by the original process. This means that
 almost no time is spent in handling the request (assuming an Emacs
 process is already running). For this to work, you need to set your
 EDITOR environment variable to 'emacsclient'. The code below, supplied
 by Francois Pinard, can then be used in your .emacs file to enable the
 server::
 
     (defvar server-buffer-clients) 
     (when (and (fboundp 'server-start) (string-equal (getenv "TERM") 'xterm)) 
       (server-start) 
       (defun fp-kill-server-with-buffer-routine () 
         (and server-buffer-clients (server-done))) 
       (add-hook 'kill-buffer-hook 'fp-kill-server-with-buffer-routine))
 
 You can also set the value of this editor via the commmand-line option
 '-editor' or in your ipythonrc file. This is useful if you wish to use
 specifically for IPython an editor different from your typical default
 (and for Windows users who tend to use fewer environment variables).
 
 
 Color
 -----
 
 The default IPython configuration has most bells and whistles turned on
 (they're pretty safe). But there's one that may cause problems on some
 systems: the use of color on screen for displaying information. This is
 very useful, since IPython can show prompts and exception tracebacks
 with various colors, display syntax-highlighted source code, and in
 general make it easier to visually parse information.
 
 The following terminals seem to handle the color sequences fine:
 
     * Linux main text console, KDE Konsole, Gnome Terminal, E-term,
       rxvt, xterm.
     * CDE terminal (tested under Solaris). This one boldfaces light colors.
     * (X)Emacs buffers. See the emacs_ section for more details on
       using IPython with (X)Emacs.
     * A Windows (XP/2k) command prompt with pyreadline_.
     * A Windows (XP/2k) CygWin shell. Although some users have reported
       problems; it is not clear whether there is an issue for everyone
       or only under specific configurations. If you have full color
       support under cygwin, please post to the IPython mailing list so
       this issue can be resolved for all users.
 
 These have shown problems:
 
     * Windows command prompt in WinXP/2k logged into a Linux machine via
       telnet or ssh.
     * Windows native command prompt in WinXP/2k, without Gary Bishop's
       extensions. Once Gary's readline library is installed, the normal
       WinXP/2k command prompt works perfectly.
 
 Currently the following color schemes are available:
 
     * NoColor: uses no color escapes at all (all escapes are empty '' ''
       strings). This 'scheme' is thus fully safe to use in any terminal.
     * Linux: works well in Linux console type environments: dark
       background with light fonts. It uses bright colors for
       information, so it is difficult to read if you have a light
       colored background.
     * LightBG: the basic colors are similar to those in the Linux scheme
       but darker. It is easy to read in terminals with light backgrounds.
 
 IPython uses colors for two main groups of things: prompts and
 tracebacks which are directly printed to the terminal, and the object
 introspection system which passes large sets of data through a pager.
 
 
 Input/Output prompts and exception tracebacks
 ---------------------------------------------
 
 You can test whether the colored prompts and tracebacks work on your
 system interactively by typing '%colors Linux' at the prompt (use
 '%colors LightBG' if your terminal has a light background). If the input
 prompt shows garbage like::
 
     [0;32mIn [[1;32m1[0;32m]: [0;00m
                                
 instead of (in color) something like::
     
     In [1]:
         
 this means that your terminal doesn't properly handle color escape
 sequences. You can go to a 'no color' mode by typing '%colors NoColor'.
 
 You can try using a different terminal emulator program (Emacs users,
 see below). To permanently set your color preferences, edit the file
 $HOME/.ipython/ipythonrc and set the colors option to the desired value.
 
 
 Object details (types, docstrings, source code, etc.)
 -----------------------------------------------------
 
 IPython has a set of special functions for studying the objects you
 are working with, discussed in detail in Sec. `dynamic object
 information`_. But this system relies on passing information which is
 longer than your screen through a data pager, such as the common Unix
 less and more programs. In order to be able to see this information in
 color, your pager needs to be properly configured. I strongly
 recommend using less instead of more, as it seems that more simply can
 not understand colored text correctly.
 
 In order to configure less as your default pager, do the following:
 
    1. Set the environment PAGER variable to less.
    2. Set the environment LESS variable to -r (plus any other options
       you always want to pass to less by default). This tells less to
       properly interpret control sequences, which is how color
       information is given to your terminal.
 
 For the csh or tcsh shells, add to your ~/.cshrc file the lines::
 
     setenv PAGER less 
     setenv LESS -r
 
 There is similar syntax for other Unix shells, look at your system
 documentation for details.
 
 If you are on a system which lacks proper data pagers (such as Windows),
 IPython will use a very limited builtin pager.
 
 .. _emacs:
 
 (X)Emacs configuration
 ----------------------
 
 Thanks to the work of Alexander Schmolck and Prabhu Ramachandran,
 currently (X)Emacs and IPython get along very well.
 
 Important note: You will need to use a recent enough version of
 python-mode.el, along with the file ipython.el. You can check that the
 version you have of python-mode.el is new enough by either looking at
 the revision number in the file itself, or asking for it in (X)Emacs via
 M-x py-version. Versions 4.68 and newer contain the necessary fixes for
 proper IPython support.
 
 The file ipython.el is included with the IPython distribution, in the
 documentation directory (where this manual resides in PDF and HTML
 formats).
 
 Once you put these files in your Emacs path, all you need in your .emacs
 file is::
 
     (require 'ipython) 
 
 This should give you full support for executing code snippets via
 IPython, opening IPython as your Python shell via C-c !, etc.
 
 If you happen to get garbage instead of colored prompts as described in
 the previous section, you may need to set also in your .emacs file::
 
     (setq ansi-color-for-comint-mode t) 
 
 
 Notes:
 
     * There is one caveat you should be aware of: you must start the
       IPython shell before attempting to execute any code regions via
       ``C-c |``. Simply type C-c ! to start IPython before passing any code
       regions to the interpreter, and you shouldn't experience any
       problems.
       This is due to a bug in Python itself, which has been fixed for
       Python 2.3, but exists as of Python 2.2.2 (reported as SF bug [
       737947 ]).
     * The (X)Emacs support is maintained by Alexander Schmolck, so all
       comments/requests should be directed to him through the IPython
       mailing lists.
     * This code is still somewhat experimental so it's a bit rough
       around the edges (although in practice, it works quite well).
     * Be aware that if you customize py-python-command previously, this
       value will override what ipython.el does (because loading the
       customization variables comes later).

 Quick tips
 ==========
 
 IPython can be used as an improved replacement for the Python prompt,
 and for that you don't really need to read any more of this manual. But
 in this section we'll try to summarize a few tips on how to make the
 most effective use of it for everyday Python development, highlighting
 things you might miss in the rest of the manual (which is getting long).
 We'll give references to parts in the manual which provide more detail
 when appropriate.
 
 The following article by Jeremy Jones provides an introductory tutorial
 about IPython:
 http://www.onlamp.com/pub/a/python/2005/01/27/ipython.html
 
     * The TAB key. TAB-completion, especially for attributes, is a
       convenient way to explore the structure of any object you're
       dealing with. Simply type object_name.<TAB> and a list of the
       object's attributes will be printed (see readline_ for
       more). Tab completion also works on
       file and directory names, which combined with IPython's alias
       system allows you to do from within IPython many of the things you
       normally would need the system shell for.
     * Explore your objects. Typing object_name? will print all sorts of
       details about any object, including docstrings, function
       definition lines (for call arguments) and constructor details for
       classes. The magic commands %pdoc, %pdef, %psource and %pfile will
       respectively print the docstring, function definition line, full
       source code and the complete file for any object (when they can be
       found). If automagic is on (it is by default), you don't need to
       type the '%' explicitly. See sec. `dynamic object information`_
       for more.
     * The %run magic command allows you to run any python script and
       load all of its data directly into the interactive namespace.
       Since the file is re-read from disk each time, changes you make to
       it are reflected immediately (in contrast to the behavior of
       import). I rarely use import for code I am testing, relying on
       %run instead. See magic_ section for more on this
       and other magic commands, or type the name of any magic command
       and ? to get details on it. See also sec. dreload_ for a
       recursive reload command.
       %run also has special flags for timing the execution of your
       scripts (-t) and for executing them under the control of either
       Python's pdb debugger (-d) or profiler (-p). With all of these,
       %run can be used as the main tool for efficient interactive
       development of code which you write in your editor of choice.
     * Use the Python debugger, pdb. The %pdb
       command allows you to toggle on and off the automatic invocation
       of an IPython-enhanced pdb debugger (with coloring, tab completion
       and more) at any uncaught exception. The advantage of this is that
       pdb starts inside the function where the exception occurred, with
       all data still available. You can print variables, see code,
       execute statements and even walk up and down the call stack to
       track down the true source of the problem (which often is many
       layers in the stack above where the exception gets triggered).
       Running programs with %run and pdb active can be an efficient to
       develop and debug code, in many cases eliminating the need for
       print statements or external debugging tools. I often simply put a
       1/0 in a place where I want to take a look so that pdb gets
       called, quickly view whatever variables I need to or test various
       pieces of code and then remove the 1/0.
       Note also that '%run -d' activates pdb and automatically sets
       initial breakpoints for you to step through your code, watch
       variables, etc. See Sec. `Output caching`_ for
       details.
     * Use the output cache. All output results are automatically stored
       in a global dictionary named Out and variables named _1, _2, etc.
       alias them. For example, the result of input line 4 is available
       either as Out[4] or as _4. Additionally, three variables named _,
       __ and ___ are always kept updated with the for the last three
       results. This allows you to recall any previous result and further
       use it for new calculations. See Sec. `Output caching`_ for more.
     * Put a ';' at the end of a line to supress the printing of output.
       This is useful when doing calculations which generate long output
       you are not interested in seeing. The _* variables and the Out[]
       list do get updated with the contents of the output, even if it is
       not printed. You can thus still access the generated results this
       way for further processing.
     * A similar system exists for caching input. All input is stored in
       a global list called In , so you can re-execute lines 22 through
       28 plus line 34 by typing 'exec In[22:29]+In[34]' (using Python
       slicing notation). If you need to execute the same set of lines
       often, you can assign them to a macro with the %macro function.
       See sec. `Input caching`_ for more.
     * Use your input history. The %hist command can show you all
       previous input, without line numbers if desired (option -n) so you
       can directly copy and paste code either back in IPython or in a
       text editor. You can also save all your history by turning on
       logging via %logstart; these logs can later be either reloaded as
       IPython sessions or used as code for your programs.
     * Define your own system aliases. Even though IPython gives you
       access to your system shell via the ! prefix, it is convenient to
       have aliases to the system commands you use most often. This
       allows you to work seamlessly from inside IPython with the same
       commands you are used to in your system shell.
       IPython comes with some pre-defined aliases and a complete system
       for changing directories, both via a stack (see %pushd, %popd and
       %dhist) and via direct %cd. The latter keeps a history of visited
       directories and allows you to go to any previously visited one.
     * Use Python to manipulate the results of system commands. The '!!'
       special syntax, and the %sc and %sx magic commands allow you to
       capture system output into Python variables.
     * Expand python variables when calling the shell (either via '!' and
       '!!' or via aliases) by prepending a $ in front of them. You can
       also expand complete python expressions. See 
       `System shell access`_ for more.
     * Use profiles to maintain different configurations (modules to
       load, function definitions, option settings) for particular tasks.
       You can then have customized versions of IPython for specific
       purposes. See sec. profiles_ for more.
     * Embed IPython in your programs. A few lines of code are enough to
       load a complete IPython inside your own programs, giving you the
       ability to work with your data interactively after automatic
       processing has been completed. See sec. embedding_
       for more.
     * Use the Python profiler. When dealing with performance issues, the
       %run command with a -p option allows you to run complete programs
       under the control of the Python profiler. The %prun command does a
       similar job for single Python expressions (like function calls).
     * Use the IPython.demo.Demo class to load any Python script as an
       interactive demo. With a minimal amount of simple markup, you can
       control the execution of the script, stopping as needed. See
       sec. `interactive demos`_ for more.
     * Run your doctests from within IPython for development and
       debugging. The special %doctest_mode command toggles a mode where
       the prompt, output and exceptions display matches as closely as
       possible that of the default Python interpreter. In addition, this
       mode allows you to directly paste in code that contains leading
       '>>>' prompts, even if they have extra leading whitespace (as is
       common in doctest files). This combined with the '%history -tn'
       call to see your translated history (with these extra prompts
       removed and no line numbers) allows for an easy doctest workflow,
       where you can go from doctest to interactive execution to pasting
       into valid Python code as needed.
 
 
 Source code handling tips
 -------------------------
 
 IPython is a line-oriented program, without full control of the
 terminal. Therefore, it doesn't support true multiline editing. However,
 it has a number of useful tools to help you in dealing effectively with
 more complex editing.
 
 The %edit command gives a reasonable approximation of multiline editing,
 by invoking your favorite editor on the spot. IPython will execute the
 code you type in there as if it were typed interactively. Type %edit?
 for the full details on the edit command.
 
 If you have typed various commands during a session, which you'd like to
 reuse, IPython provides you with a number of tools. Start by using %hist
 to see your input history, so you can see the line numbers of all input.
 Let us say that you'd like to reuse lines 10 through 20, plus lines 24
 and 28. All the commands below can operate on these with the syntax::
 
     %command 10-20 24 28 
 
 where the command given can be:
 
     * %macro <macroname>: this stores the lines into a variable which,
       when called at the prompt, re-executes the input. Macros can be
       edited later using '%edit macroname', and they can be stored
       persistently across sessions with '%store macroname' (the storage
       system is per-profile). The combination of quick macros,
       persistent storage and editing, allows you to easily refine
       quick-and-dirty interactive input into permanent utilities, always
       available both in IPython and as files for general reuse.
     * %edit: this will open a text editor with those lines pre-loaded
       for further modification. It will then execute the resulting
       file's contents as if you had typed it at the prompt.
     * %save <filename>: this saves the lines directly to a named file on
       disk.
 
 While %macro saves input lines into memory for interactive re-execution,
 sometimes you'd like to save your input directly to a file. The %save
 magic does this: its input sytnax is the same as %macro, but it saves
 your input directly to a Python file. Note that the %logstart command
 also saves input, but it logs all input to disk (though you can
 temporarily suspend it and reactivate it with %logoff/%logon); %save
 allows you to select which lines of input you need to save.
 
 
 Lightweight 'version control'
 -----------------------------
 
 When you call %edit with no arguments, IPython opens an empty editor
 with a temporary file, and it returns the contents of your editing
 session as a string variable. Thanks to IPython's output caching
 mechanism, this is automatically stored::
 
     In [1]: %edit
 
     IPython will make a temporary file named: /tmp/ipython_edit_yR-HCN.py
 
     Editing... done. Executing edited code...
 
     hello - this is a temporary file
 
     Out[1]: "print 'hello - this is a temporary file'\n"
 
 Now, if you call '%edit -p', IPython tries to open an editor with the
 same data as the last time you used %edit. So if you haven't used %edit
 in the meantime, this same contents will reopen; however, it will be
 done in a new file. This means that if you make changes and you later
 want to find an old version, you can always retrieve it by using its
 output number, via '%edit _NN', where NN is the number of the output
 prompt.
 
 Continuing with the example above, this should illustrate this idea::
 
     In [2]: edit -p
 
     IPython will make a temporary file named: /tmp/ipython_edit_nA09Qk.py
 
     Editing... done. Executing edited code...
 
     hello - now I made some changes
 
     Out[2]: "print 'hello - now I made some changes'\n"
 
     In [3]: edit _1
 
     IPython will make a temporary file named: /tmp/ipython_edit_gy6-zD.py
 
     Editing... done. Executing edited code...
 
     hello - this is a temporary file
 
     IPython version control at work :)
 
     Out[3]: "print 'hello - this is a temporary file'\nprint 'IPython version control at work :)'\n"
 
 
 This section was written after a contribution by Alexander Belchenko on
 the IPython user list.
 
 
 Effective logging
 -----------------
 
 A very useful suggestion sent in by Robert Kern follows:
 
 I recently happened on a nifty way to keep tidy per-project log files. I
 made a profile for my project (which is called "parkfield").
 
     include ipythonrc
 
     # cancel earlier logfile invocation:
 
     logfile ''
 
     execute import time
 
     execute __cmd = '/Users/kern/research/logfiles/parkfield-%s.log rotate'
 
     execute __IP.magic_logstart(__cmd % time.strftime('%Y-%m-%d'))
 
 I also added a shell alias for convenience:
 
     alias parkfield="ipython -pylab -profile parkfield" 
 
 Now I have a nice little directory with everything I ever type in,
 organized by project and date.
 
 Contribute your own: If you have your own favorite tip on using IPython
 efficiently for a certain task (especially things which can't be done in
 the normal Python interpreter), don't hesitate to send it!
 
 .. _Command line options:
 
 Command-line use
 ================
 
 You start IPython with the command::
 
     $ ipython [options] files
 
 If invoked with no options, it executes all the files listed in sequence
 and drops you into the interpreter while still acknowledging any options
 you may have set in your ipythonrc file. This behavior is different from
 standard Python, which when called as python -i will only execute one
 file and ignore your configuration setup.
 
 Please note that some of the configuration options are not available at
 the command line, simply because they are not practical here. Look into
 your ipythonrc configuration file for details on those. This file
 typically installed in the $HOME/.ipython directory. For Windows users,
 $HOME resolves to C:\\Documents and Settings\\YourUserName in most
 instances. In the rest of this text, we will refer to this directory as
 IPYTHONDIR.
 
 .. _Threading options:
 
 
 Special Threading Options
 -------------------------
 
 The following special options are ONLY valid at the beginning of the
 command line, and not later. This is because they control the initial-
 ization of ipython itself, before the normal option-handling mechanism
 is active.
 
     -gthread, -qthread, -q4thread, -wthread, -pylab: 
 	Only one of these can be given, and it can only be given as
 	the first option passed to IPython (it will have no effect in
 	any other position).  They provide threading support for the
 	GTK, Qt (versions 3 and 4) and WXPython toolkits, and for the
 	matplotlib library.
 
 	With any of the first four options, IPython starts running a
 	separate thread for the graphical toolkit's operation, so that
 	you can open and control graphical elements from within an
 	IPython command line, without blocking. All four provide
 	essentially the same functionality, respectively for GTK, Qt3,
 	Qt4 and WXWidgets (via their Python interfaces).
 
 	Note that with -wthread, you can additionally use the
 	-wxversion option to request a specific version of wx to be
 	used.  This requires that you have the wxversion Python module
 	installed, which is part of recent wxPython distributions.
 
 	If -pylab is given, IPython loads special support for the mat
 	plotlib library (http://matplotlib.sourceforge.net), allowing
 	interactive usage of any of its backends as defined in the
 	user's ~/.matplotlib/matplotlibrc file. It automatically
 	activates GTK, Qt or WX threading for IPyhton if the choice of
 	matplotlib backend requires it. It also modifies the %run
 	command to correctly execute (without blocking) any
 	matplotlib-based script which calls show() at the end.
 
     -tk
 	The -g/q/q4/wthread options, and -pylab (if matplotlib is
 	configured to use GTK, Qt3, Qt4 or WX), will normally block Tk
 	graphical interfaces. This means that when either GTK, Qt or WX
 	threading is active, any attempt to open a Tk GUI will result in a
 	dead window, and possibly cause the Python interpreter to crash.
 	An extra option, -tk, is available to address this issue. It can
 	only be given as a second option after any of the above (-gthread,
 	-wthread or -pylab).
 
 	If -tk is given, IPython will try to coordinate Tk threading
 	with GTK, Qt or WX. This is however potentially unreliable, and
 	you will have to test on your platform and Python configuration to
 	determine whether it works for you. Debian users have reported
 	success, apparently due to the fact that Debian builds all of Tcl,
 	Tk, Tkinter and Python with pthreads support. Under other Linux
 	environments (such as Fedora Core 2/3), this option has caused
 	random crashes and lockups of the Python interpreter. Under other
 	operating systems (Mac OSX and Windows), you'll need to try it to
 	find out, since currently no user reports are available.
     
 	There is unfortunately no way for IPython to determine at run time
 	whether -tk will work reliably or not, so you will need to do some
 	experiments before relying on it for regular work.
 
 
 
 Regular Options
 ---------------
 
 After the above threading options have been given, regular options can
 follow in any order. All options can be abbreviated to their shortest
 non-ambiguous form and are case-sensitive. One or two dashes can be
 used. Some options have an alternate short form, indicated after a ``|``.
 
 Most options can also be set from your ipythonrc configuration file. See
 the provided example for more details on what the options do. Options
 given at the command line override the values set in the ipythonrc file.
 
 All options with a [no] prepended can be specified in negated form
 (-nooption instead of -option) to turn the feature off.
 
     -help  print a help message and exit.
 
     -pylab
 	this can only be given as the first option passed to IPython
 	(it will have no effect in any other position). It adds
 	special support for the matplotlib library
 	(http://matplotlib.sourceforge.ne), allowing interactive usage
 	of any of its backends as defined in the user's .matplotlibrc
 	file.  It automatically activates GTK or WX threading for
 	IPyhton if the choice of matplotlib backend requires it. It
 	also modifies the %run command to correctly execute (without
 	blocking) any matplotlib-based script which calls show() at
 	the end. See `Matplotlib support`_ for more details.
 
     -autocall <val>
 	Make IPython automatically call any callable object even if you
 	didn't type explicit parentheses. For example, 'str 43' becomes
 	'str(43)' automatically. The value can be '0' to disable the feature,
 	'1' for smart autocall, where it is not applied if there are no more
 	arguments on the line, and '2' for full autocall, where all callable
 	objects are automatically called (even if no arguments are
 	present). The default is '1'.
 
     -[no]autoindent    
 	Turn automatic indentation on/off.
 
     -[no]automagic 
 	make magic commands automatic (without needing their first character
 	to be %). Type %magic at the IPython prompt for more information.
 
     -[no]autoedit_syntax 
 	When a syntax error occurs after editing a file, automatically
 	open the file to the trouble causing line for convenient
 	fixing.
 
     -[no]banner		Print the initial information banner (default on).
 
     -c <command>
 	execute the given command string. This is similar to the -c
 	option in the normal Python interpreter.
 
     -cache_size, cs <n> 
 	size of the output cache (maximum number of entries to hold in
 	memory). The default is 1000, you can change it permanently in your
 	config file. Setting it to 0 completely disables the caching system,
 	and the minimum value accepted is 20 (if you provide a value less than
 	20, it is reset to 0 and a warning is issued) This limit is defined
 	because otherwise you'll spend more time re-flushing a too small cache
 	than working.
 
     -classic, cl 
 	Gives IPython a similar feel to the classic Python
 	prompt.
 
     -colors <scheme> 
 	Color scheme for prompts and exception reporting. Currently
 	implemented: NoColor, Linux and LightBG.
 
     -[no]color_info 
 	IPython can display information about objects via a set of functions,
 	and optionally can use colors for this, syntax highlighting source
 	code and various other elements.  However, because this information is
 	passed through a pager (like 'less') and many pagers get confused with
 	color codes, this option is off by default. You can test it and turn
 	it on permanently in your ipythonrc file if it works for you. As a
 	reference, the 'less' pager supplied with Mandrake 8.2 works ok, but
 	that in RedHat 7.2 doesn't.
 
 	Test it and turn it on permanently if it works with your
 	system. The magic function %color_info allows you to toggle this
 	interactively for testing.
 
     -[no]debug 
 	Show information about the loading process. Very useful to pin down
 	problems with your configuration files or to get details about
 	session restores.
 
     -[no]deep_reload: 
 	IPython can use the deep_reload module which reloads changes in
 	modules recursively (it replaces the reload() function, so you don't
 	need to change anything to use it).  deep_reload() forces a full
 	reload of modules whose code may have changed, which the default
 	reload() function does not.
 
 	When deep_reload is off, IPython will use the normal reload(),
 	but deep_reload will still be available as dreload(). This
 	feature is off by default [which means that you have both
 	normal reload() and dreload()].
 
     -editor <name>
 	Which editor to use with the %edit command. By default,
 	IPython will honor your EDITOR environment variable (if not
 	set, vi is the Unix default and notepad the Windows one).
 	Since this editor is invoked on the fly by IPython and is
 	meant for editing small code snippets, you may want to use a
 	small, lightweight editor here (in case your default EDITOR is
 	something like Emacs).
 
     -ipythondir <name> 
 	name of your IPython configuration directory IPYTHONDIR. This
 	can also be specified through the environment variable
 	IPYTHONDIR.
 
     -log, l 
 	generate a log file of all input. The file is named
 	ipython_log.py in your current directory (which prevents logs
 	from multiple IPython sessions from trampling each other). You
 	can use this to later restore a session by loading your
 	logfile as a file to be executed with option -logplay (see
 	below).
 
     -logfile, lf <name>   specify the name of your logfile.
 
     -logplay, lp <name> 
 
       you can replay a previous log. For restoring a session as close as
       possible to the state you left it in, use this option (don't just run
       the logfile). With -logplay, IPython will try to reconstruct the
       previous working environment in full, not just execute the commands in
       the logfile.
 
       When a session is restored, logging is automatically turned on
       again with the name of the logfile it was invoked with (it is
       read from the log header). So once you've turned logging on for
       a session, you can quit IPython and reload it as many times as
       you want and it will continue to log its history and restore
       from the beginning every time.
       
       Caveats: there are limitations in this option. The history
       variables _i*,_* and _dh don't get restored properly. In the
       future we will try to implement full session saving by writing
       and retrieving a 'snapshot' of the memory state of IPython. But
       our first attempts failed because of inherent limitations of
       Python's Pickle module, so this may have to wait.
 
     -[no]messages   
 	Print messages which IPython collects about its startup
 	process (default on).
 
     -[no]pdb
 	Automatically call the pdb debugger after every uncaught
 	exception. If you are used to debugging using pdb, this puts
 	you automatically inside of it after any call (either in
 	IPython or in code called by it) which triggers an exception
 	which goes uncaught.
 
+    -pydb
+	Makes IPython use the third party "pydb" package as debugger,
+	instead of pdb. Requires that pydb is installed.
+	
     -[no]pprint
 	ipython can optionally use the pprint (pretty printer) module
 	for displaying results. pprint tends to give a nicer display
 	of nested data structures. If you like it, you can turn it on
 	permanently in your config file (default off).
 
     -profile, p <name>
 
 	assume that your config file is ipythonrc-<name> or
 	ipy_profile_<name>.py (looks in current dir first, then in
 	IPYTHONDIR).  This is a quick way to keep and load multiple
 	config files for different tasks, especially if you use the
 	include option of config files. You can keep a basic
 	IPYTHONDIR/ipythonrc file and then have other 'profiles' which
 	include this one and load extra things for particular
 	tasks. For example:
 
 	1. $HOME/.ipython/ipythonrc : load basic things you always want.
 	2. $HOME/.ipython/ipythonrc-math : load (1) and basic math-related modules.
 	3. $HOME/.ipython/ipythonrc-numeric : load (1) and Numeric and plotting modules.
 
 	Since it is possible to create an endless loop by having
 	circular file inclusions, IPython will stop if it reaches 15
 	recursive inclusions.
 
     -prompt_in1, pi1 <string>
 	Specify the string used for input prompts. Note that if you
 	are using numbered prompts, the number is represented with a
 	'\#' in the string. Don't forget to quote strings with spaces
 	embedded in them. Default: 'In [\#]:'.  Sec. Prompts_
 	discusses in detail all the available escapes to customize
 	your prompts.
 
     -prompt_in2, pi2 <string>
 	Similar to the previous option, but used for the continuation
 	prompts. The special sequence '\D' is similar to '\#', but
 	with all digits replaced dots (so you can have your
 	continuation prompt aligned with your input prompt).  Default:
 	' .\D.:' (note three spaces at the start for alignment with
 	'In [\#]').
 
     -prompt_out,po <string> 
 	String used for output prompts, also uses numbers like
 	prompt_in1. Default: 'Out[\#]:'
 
     -quick   start in bare bones mode (no config file loaded).
 
     -rcfile <name>   
 	name of your IPython resource configuration file. Normally
 	IPython loads ipythonrc (from current directory) or
 	IPYTHONDIR/ipythonrc.
 
 	If the loading of your config file fails, IPython starts with
 	a bare bones configuration (no modules loaded at all).
 
     -[no]readline
 	use the readline library, which is needed to support name
 	completion and command history, among other things.  It is
 	enabled by default, but may cause problems for users of
 	X/Emacs in Python comint or shell buffers.
 
 	Note that X/Emacs 'eterm' buffers (opened with M-x term) support
 	IPython's readline and syntax coloring fine, only 'emacs' (M-x
 	shell and C-c !) buffers do not.
 
     -screen_length, sl <n>
 	number of lines of your screen. This is used to control
 	printing of very long strings. Strings longer than this number
 	of lines will be sent through a pager instead of directly
 	printed.
 
 	The default value for this is 0, which means IPython will
 	auto-detect your screen size every time it needs to print certain
 	potentially long strings (this doesn't change the behavior of the
 	'print' keyword, it's only triggered internally). If for some
 	reason this isn't working well (it needs curses support), specify
 	it yourself. Otherwise don't change the default.
 
     -separate_in, si <string>
 
 	separator before input prompts.
 	Default: '\n'
 
     -separate_out, so <string>  
         separator before output prompts.
         Default: nothing.
 
     -separate_out2, so2
 	separator after output prompts.
 	Default: nothing.
 	For these three options, use the value 0 to specify no separator.
 
     -nosep   
 	shorthand for '-SeparateIn 0 -SeparateOut 0 -SeparateOut2
 	0'. Simply removes all input/output separators.
 
     -upgrade 
 	allows you to upgrade your IPYTHONDIR configuration when you
 	install a new version of IPython. Since new versions may
 	include new command line options or example files, this copies
 	updated ipythonrc-type files. However, it backs up (with a
 	.old extension) all files which it overwrites so that you can
 	merge back any customizations you might have in your personal
 	files. Note that you should probably use %upgrade instead,
 	it's a safer alternative.
 
 
     -Version    print version information and exit.
 
     -wxversion <string> 
 	Select a specific version of wxPython (used in conjunction
 	with -wthread). Requires the wxversion module, part of recent
 	wxPython distributions
 
     -xmode <modename>
 
 	Mode for exception reporting.
 
 	Valid modes: Plain, Context and Verbose.
 
 	* Plain: similar to python's normal traceback printing.
 	* Context: prints 5 lines of context source code around each
 	  line in the traceback.
 	* Verbose: similar to Context, but additionally prints the
 	  variables currently visible where the exception happened
 	  (shortening their strings if too long). This can potentially be
 	  very slow, if you happen to have a huge data structure whose
 	  string representation is complex to compute. Your computer may
 	  appear to freeze for a while with cpu usage at 100%. If this
 	  occurs, you can cancel the traceback with Ctrl-C (maybe hitting it
 	  more than once).
 
 Interactive use
 ===============
 
 Warning: IPython relies on the existence of a global variable called
 _ip which controls the shell itself. If you redefine _ip to anything,
 bizarre behavior will quickly occur.
 
 Other than the above warning, IPython is meant to work as a drop-in
 replacement for the standard interactive interpreter. As such, any code
 which is valid python should execute normally under IPython (cases where
 this is not true should be reported as bugs). It does, however, offer
 many features which are not available at a standard python prompt. What
 follows is a list of these.
 
 
 Caution for Windows users
 -------------------------
 
 Windows, unfortunately, uses the '\' character as a path
 separator. This is a terrible choice, because '\' also represents the
 escape character in most modern programming languages, including
 Python. For this reason, using '/' character is recommended if you
 have problems with ``\``.  However, in Windows commands '/' flags
 options, so you can not use it for the root directory. This means that
 paths beginning at the root must be typed in a contrived manner like:
 ``%copy \opt/foo/bar.txt \tmp``
 
 .. _magic:
 
 Magic command system
 --------------------
 
 IPython will treat any line whose first character is a % as a special
 call to a 'magic' function. These allow you to control the behavior of
 IPython itself, plus a lot of system-type features. They are all
 prefixed with a % character, but parameters are given without
 parentheses or quotes.
 
 Example: typing '%cd mydir' (without the quotes) changes you working
 directory to 'mydir', if it exists.
 
 If you have 'automagic' enabled (in your ipythonrc file, via the command
 line option -automagic or with the %automagic function), you don't need
 to type in the % explicitly. IPython will scan its internal list of
 magic functions and call one if it exists. With automagic on you can
 then just type 'cd mydir' to go to directory 'mydir'. The automagic
 system has the lowest possible precedence in name searches, so defining
 an identifier with the same name as an existing magic function will
 shadow it for automagic use. You can still access the shadowed magic
 function by explicitly using the % character at the beginning of the line.
 
 An example (with automagic on) should clarify all this::
 
     In [1]: cd ipython # %cd is called by automagic
 
     /home/fperez/ipython
 
     In [2]: cd=1 # now cd is just a variable
 
     In [3]: cd .. # and doesn't work as a function anymore
 
     ------------------------------
 
         File "<console>", line 1
 
           cd ..
 
               ^
 
     SyntaxError: invalid syntax
 
     In [4]: %cd .. # but %cd always works
 
     /home/fperez
 
     In [5]: del cd # if you remove the cd variable
 
     In [6]: cd ipython # automagic can work again
 
     /home/fperez/ipython
 
 You can define your own magic functions to extend the system. The
 following example defines a new magic command, %impall::
 
     import IPython.ipapi 
 
     ip = IPython.ipapi.get()
 
     def doimp(self, arg):
 
         ip = self.api
 
         ip.ex("import %s; reload(%s); from %s import *" % (
 
         arg,arg,arg)
 
         )
 
     ip.expose_magic('impall', doimp)
 
 You can also define your own aliased names for magic functions. In your
 ipythonrc file, placing a line like:
 
 execute __IP.magic_cl = __IP.magic_clear
 
 will define %cl as a new name for %clear.
 
 Type %magic for more information, including a list of all available
 magic functions at any time and their docstrings. You can also type
 %magic_function_name? (see sec. 6.4 <#sec:dyn-object-info> for
 information on the '?' system) to get information about any particular
 magic function you are interested in.
 
 
 Magic commands
 --------------
 
 The rest of this section is automatically generated for each release
 from the docstrings in the IPython code. Therefore the formatting is
 somewhat minimal, but this method has the advantage of having
 information always in sync with the code.
 
 A list of all the magic commands available in IPython's default
 installation follows. This is similar to what you'll see by simply
 typing %magic at the prompt, but that will also give you information
 about magic commands you may have added as part of your personal
 customizations.
 
 .. magic_start
 
 **%Exit**::
 
 	Exit IPython without confirmation.
 
 **%Pprint**::
 
 	Toggle pretty printing on/off.
 
 **%alias**::
 
 	Define an alias for a system command.
 
         '%alias alias_name cmd' defines 'alias_name' as an alias for 'cmd'
 
         Then, typing 'alias_name params' will execute the system command 'cmd
         params' (from your underlying operating system).
 
         Aliases have lower precedence than magic functions and Python normal
         variables, so if 'foo' is both a Python variable and an alias, the
         alias can not be executed until 'del foo' removes the Python variable.
 
         You can use the %l specifier in an alias definition to represent the
         whole line when the alias is called.  For example:
 
           In [2]: alias all echo "Input in brackets: <%l>"\
           In [3]: all hello world\
           Input in brackets: <hello world>
 
         You can also define aliases with parameters using %s specifiers (one
         per parameter):
         
           In [1]: alias parts echo first %s second %s\
           In [2]: %parts A B\
           first A second B\
           In [3]: %parts A\
           Incorrect number of arguments: 2 expected.\
           parts is an alias to: 'echo first %s second %s'
 
         Note that %l and %s are mutually exclusive.  You can only use one or
         the other in your aliases.
 
         Aliases expand Python variables just like system calls using ! or !! 
         do: all expressions prefixed with '$' get expanded.  For details of
         the semantic rules, see PEP-215:
         http://www.python.org/peps/pep-0215.html.  This is the library used by
         IPython for variable expansion.  If you want to access a true shell
         variable, an extra $ is necessary to prevent its expansion by IPython:
 
         In [6]: alias show echo\
         In [7]: PATH='A Python string'\
         In [8]: show $PATH\
         A Python string\
         In [9]: show $$PATH\
         /usr/local/lf9560/bin:/usr/local/intel/compiler70/ia32/bin:...
 
         You can use the alias facility to acess all of $PATH.  See the %rehash
         and %rehashx functions, which automatically create aliases for the
         contents of your $PATH.
 
         If called with no parameters, %alias prints the current alias table.
 
 **%autocall**::
 
 	Make functions callable without having to type parentheses.
 
         Usage:
 
            %autocall [mode]
 
         The mode can be one of: 0->Off, 1->Smart, 2->Full.  If not given, the
         value is toggled on and off (remembering the previous state).
 
         In more detail, these values mean:
 
         0 -> fully disabled
 
         1 -> active, but do not apply if there are no arguments on the line.
 
         In this mode, you get:
 
         In [1]: callable
         Out[1]: <built-in function callable>
 
         In [2]: callable 'hello'
         ------> callable('hello')
         Out[2]: False
 
         2 -> Active always.  Even if no arguments are present, the callable
         object is called:
 
         In [4]: callable
         ------> callable()
 
         Note that even with autocall off, you can still use '/' at the start of
         a line to treat the first argument on the command line as a function
         and add parentheses to it:
 
         In [8]: /str 43
         ------> str(43)
         Out[8]: '43'
 
 **%autoindent**::
 
 	Toggle autoindent on/off (if available).
 
 **%automagic**::
 
 	Make magic functions callable without having to type the initial %.
 
         Without argumentsl toggles on/off (when off, you must call it as
         %automagic, of course).  With arguments it sets the value, and you can
         use any of (case insensitive):
 
          - on,1,True: to activate
 
          - off,0,False: to deactivate.
 
         Note that magic functions have lowest priority, so if there's a
         variable whose name collides with that of a magic fn, automagic won't
         work for that function (you get the variable instead). However, if you
         delete the variable (del var), the previously shadowed magic function
         becomes visible to automagic again.
 
 **%bg**::
 
 	Run a job in the background, in a separate thread.
 
         For example,
 
           %bg myfunc(x,y,z=1)
 
         will execute 'myfunc(x,y,z=1)' in a background thread.  As soon as the
         execution starts, a message will be printed indicating the job
         number.  If your job number is 5, you can use
 
           myvar = jobs.result(5)  or  myvar = jobs[5].result
 
         to assign this result to variable 'myvar'.
 
         IPython has a job manager, accessible via the 'jobs' object.  You can
         type jobs? to get more information about it, and use jobs.<TAB> to see
         its attributes.  All attributes not starting with an underscore are
         meant for public use.
 
         In particular, look at the jobs.new() method, which is used to create
         new jobs.  This magic %bg function is just a convenience wrapper
         around jobs.new(), for expression-based jobs.  If you want to create a
         new job with an explicit function object and arguments, you must call
         jobs.new() directly.
 
         The jobs.new docstring also describes in detail several important
         caveats associated with a thread-based model for background job
         execution.  Type jobs.new? for details.
 
         You can check the status of all jobs with jobs.status().
 
         The jobs variable is set by IPython into the Python builtin namespace.
         If you ever declare a variable named 'jobs', you will shadow this
         name.  You can either delete your global jobs variable to regain
         access to the job manager, or make a new name and assign it manually
         to the manager (stored in IPython's namespace).  For example, to
         assign the job manager to the Jobs name, use:
 
           Jobs = __builtins__.jobs
 
 **%bookmark**::
 
 	Manage IPython's bookmark system.
 
         %bookmark <name>       - set bookmark to current dir
         %bookmark <name> <dir> - set bookmark to <dir>
         %bookmark -l           - list all bookmarks
         %bookmark -d <name>    - remove bookmark
         %bookmark -r           - remove all bookmarks
 
         You can later on access a bookmarked folder with:
           %cd -b <name>
         or simply '%cd <name>' if there is no directory called <name> AND
         there is such a bookmark defined.
 
         Your bookmarks persist through IPython sessions, but they are
         associated with each profile.
 
 **%cd**::
 
 	Change the current working directory.
 
         This command automatically maintains an internal list of directories
         you visit during your IPython session, in the variable _dh. The
         command %dhist shows this history nicely formatted. You can also
         do 'cd -<tab>' to see directory history conveniently.
 
         Usage:
 
           cd 'dir': changes to directory 'dir'.
 
           cd -: changes to the last visited directory.
 
           cd -<n>: changes to the n-th directory in the directory history.
 
           cd -b <bookmark_name>: jump to a bookmark set by %bookmark
              (note: cd <bookmark_name> is enough if there is no
               directory <bookmark_name>, but a bookmark with the name exists.)
               'cd -b <tab>' allows you to tab-complete bookmark names. 
 
         Options:
 
         -q: quiet.  Do not print the working directory after the cd command is
         executed.  By default IPython's cd command does print this directory,
         since the default prompts do not display path information.
         
         Note that !cd doesn't work for this purpose because the shell where
         !command runs is immediately discarded after executing 'command'.
 
 **%clear**::
 
 	 Clear various data (e.g. stored history data)
     
     %clear out - clear output history
     %clear in  - clear input history
     %clear shadow_compress - Compresses shadow history (to speed up ipython)
     %clear shadow_nuke - permanently erase all entries in shadow history
     %clear dhist - clear dir history
 
 **%color_info**::
 
 	Toggle color_info.
 
         The color_info configuration parameter controls whether colors are
         used for displaying object details (by things like %psource, %pfile or
         the '?' system). This function toggles this value with each call.
 
         Note that unless you have a fairly recent pager (less works better
         than more) in your system, using colored object information displays
         will not work properly. Test it and see.
 
 **%colors**::
 
 	Switch color scheme for prompts, info system and exception handlers.
 
         Currently implemented schemes: NoColor, Linux, LightBG.
 
         Color scheme names are not case-sensitive.
 
 **%cpaste**::
 
 	Allows you to paste & execute a pre-formatted code block from clipboard
         
         You must terminate the block with '--' (two minus-signs) alone on the
         line. You can also provide your own sentinel with '%paste -s %%' ('%%' 
         is the new sentinel for this operation)
         
         The block is dedented prior to execution to enable execution of method
         definitions. '>' and '+' characters at the beginning of a line are
         ignored, to allow pasting directly from e-mails or diff files. The
         executed block is also assigned to variable named 'pasted_block' for
         later editing with '%edit pasted_block'.
         
         You can also pass a variable name as an argument, e.g. '%cpaste foo'.
         This assigns the pasted block to variable 'foo' as string, without 
         dedenting or executing it.
         
         Do not be alarmed by garbled output on Windows (it's a readline bug). 
         Just press enter and type -- (and press enter again) and the block 
         will be what was just pasted.
         
         IPython statements (magics, shell escapes) are not supported (yet).
 
 **%debug**::
 
 	Activate the interactive debugger in post-mortem mode.
 
         If an exception has just occurred, this lets you inspect its stack
         frames interactively.  Note that this will always work only on the last
         traceback that occurred, so you must call this quickly after an
         exception that you wish to inspect has fired, because if another one
         occurs, it clobbers the previous one.
 
         If you want IPython to automatically do this on every exception, see
         the %pdb magic for more details.
 
 **%dhist**::
 
 	Print your history of visited directories.
 
         %dhist       -> print full history\
         %dhist n     -> print last n entries only\
         %dhist n1 n2 -> print entries between n1 and n2 (n1 not included)\
 
         This history is automatically maintained by the %cd command, and
         always available as the global list variable _dh. You can use %cd -<n>
         to go to directory number <n>.
         
         Note that most of time, you should view directory history by entering
         cd -<TAB>.
 
 **%dirs**::
 
 	Return the current directory stack.
 
 **%doctest_mode**::
 
 	Toggle doctest mode on and off.
 
         This mode allows you to toggle the prompt behavior between normal
         IPython prompts and ones that are as similar to the default IPython
         interpreter as possible.
 
         It also supports the pasting of code snippets that have leading '>>>'
         and '...' prompts in them.  This means that you can paste doctests from
         files or docstrings (even if they have leading whitespace), and the
         code will execute correctly.  You can then use '%history -tn' to see
         the translated history without line numbers; this will give you the
         input after removal of all the leading prompts and whitespace, which
         can be pasted back into an editor.
 
         With these features, you can switch into this mode easily whenever you
         need to do testing and changes to doctests, without having to leave
         your existing IPython session.
 
 **%ed**::
 
 	Alias to %edit.
 
 **%edit**::
 
 	Bring up an editor and execute the resulting code.
 
         Usage:
           %edit [options] [args]
 
         %edit runs IPython's editor hook.  The default version of this hook is
         set to call the __IPYTHON__.rc.editor command.  This is read from your
         environment variable $EDITOR.  If this isn't found, it will default to
         vi under Linux/Unix and to notepad under Windows.  See the end of this
         docstring for how to change the editor hook.
 
         You can also set the value of this editor via the command line option
         '-editor' or in your ipythonrc file. This is useful if you wish to use
         specifically for IPython an editor different from your typical default
         (and for Windows users who typically don't set environment variables).
 
         This command allows you to conveniently edit multi-line code right in
         your IPython session.
         
         If called without arguments, %edit opens up an empty editor with a
         temporary file and will execute the contents of this file when you
         close it (don't forget to save it!).
 
 
         Options:
 
         -n <number>: open the editor at a specified line number.  By default,
         the IPython editor hook uses the unix syntax 'editor +N filename', but
         you can configure this by providing your own modified hook if your
         favorite editor supports line-number specifications with a different
         syntax.
         
         -p: this will call the editor with the same data as the previous time
         it was used, regardless of how long ago (in your current session) it
         was.
 
         -r: use 'raw' input.  This option only applies to input taken from the
         user's history.  By default, the 'processed' history is used, so that
         magics are loaded in their transformed version to valid Python.  If
         this option is given, the raw input as typed as the command line is
         used instead.  When you exit the editor, it will be executed by
         IPython's own processor.
         
         -x: do not execute the edited code immediately upon exit. This is
         mainly useful if you are editing programs which need to be called with
         command line arguments, which you can then do using %run.
 
 
         Arguments:
 
         If arguments are given, the following possibilites exist:
 
         - The arguments are numbers or pairs of colon-separated numbers (like
         1 4:8 9). These are interpreted as lines of previous input to be
         loaded into the editor. The syntax is the same of the %macro command.
 
         - If the argument doesn't start with a number, it is evaluated as a
         variable and its contents loaded into the editor. You can thus edit
         any string which contains python code (including the result of
         previous edits).
 
         - If the argument is the name of an object (other than a string),
         IPython will try to locate the file where it was defined and open the
         editor at the point where it is defined. You can use `%edit function`
         to load an editor exactly at the point where 'function' is defined,
         edit it and have the file be executed automatically.
 
         If the object is a macro (see %macro for details), this opens up your
         specified editor with a temporary file containing the macro's data.
         Upon exit, the macro is reloaded with the contents of the file.
 
         Note: opening at an exact line is only supported under Unix, and some
         editors (like kedit and gedit up to Gnome 2.8) do not understand the
         '+NUMBER' parameter necessary for this feature. Good editors like
         (X)Emacs, vi, jed, pico and joe all do.
 
         - If the argument is not found as a variable, IPython will look for a
         file with that name (adding .py if necessary) and load it into the
         editor. It will execute its contents with execfile() when you exit,
         loading any code in the file into your interactive namespace.
 
         After executing your code, %edit will return as output the code you
         typed in the editor (except when it was an existing file). This way
         you can reload the code in further invocations of %edit as a variable,
         via _<NUMBER> or Out[<NUMBER>], where <NUMBER> is the prompt number of
         the output.
 
         Note that %edit is also available through the alias %ed.
 
         This is an example of creating a simple function inside the editor and
         then modifying it. First, start up the editor:
 
         In [1]: ed\
         Editing... done. Executing edited code...\
         Out[1]: 'def foo():\n    print "foo() was defined in an editing session"\n'
 
         We can then call the function foo():
         
         In [2]: foo()\
         foo() was defined in an editing session
 
         Now we edit foo.  IPython automatically loads the editor with the
         (temporary) file where foo() was previously defined:
         
         In [3]: ed foo\
         Editing... done. Executing edited code...
 
         And if we call foo() again we get the modified version:
         
         In [4]: foo()\
         foo() has now been changed!
 
         Here is an example of how to edit a code snippet successive
         times. First we call the editor:
 
         In [8]: ed\
         Editing... done. Executing edited code...\
         hello\
         Out[8]: "print 'hello'\n"
 
         Now we call it again with the previous output (stored in _):
 
         In [9]: ed _\
         Editing... done. Executing edited code...\
         hello world\
         Out[9]: "print 'hello world'\n"
 
         Now we call it with the output #8 (stored in _8, also as Out[8]):
 
         In [10]: ed _8\
         Editing... done. Executing edited code...\
         hello again\
         Out[10]: "print 'hello again'\n"
 
 
         Changing the default editor hook:
 
         If you wish to write your own editor hook, you can put it in a
         configuration file which you load at startup time.  The default hook
         is defined in the IPython.hooks module, and you can use that as a
         starting example for further modifications.  That file also has
         general instructions on how to set a new hook for use once you've
         defined it.
 
 **%env**::
 
 	List environment variables.
 
 **%exit**::
 
 	Exit IPython, confirming if configured to do so.
 
         You can configure whether IPython asks for confirmation upon exit by
         setting the confirm_exit flag in the ipythonrc file.
 
 **%hist**::
 
 	Alternate name for %history.
 
 **%history**::
 
 	Print input history (_i<n> variables), with most recent last.
     
     %history       -> print at most 40 inputs (some may be multi-line)\
     %history n     -> print at most n inputs\
     %history n1 n2 -> print inputs between n1 and n2 (n2 not included)\
     
     Each input's number <n> is shown, and is accessible as the
     automatically generated variable _i<n>.  Multi-line statements are
     printed starting at a new line for easy copy/paste.
     
 
     Options:
 
       -n: do NOT print line numbers. This is useful if you want to get a
       printout of many lines which can be directly pasted into a text
       editor.
 
       This feature is only available if numbered prompts are in use.
 
       -t: (default) print the 'translated' history, as IPython understands it.
       IPython filters your input and converts it all into valid Python source
       before executing it (things like magics or aliases are turned into
       function calls, for example). With this option, you'll see the native
       history instead of the user-entered version: '%cd /' will be seen as
       '_ip.magic("%cd /")' instead of '%cd /'.
       
       -r: print the 'raw' history, i.e. the actual commands you typed.
       
       -g: treat the arg as a pattern to grep for in (full) history.
       This includes the "shadow history" (almost all commands ever written).
       Use '%hist -g' to show full shadow history (may be very long).
       In shadow history, every index nuwber starts with 0.
 
       -f FILENAME: instead of printing the output to the screen, redirect it to
        the given file.  The file is always overwritten, though IPython asks for
        confirmation first if it already exists.
 
 **%logoff**::
 
 	Temporarily stop logging.
 
         You must have previously started logging.
 
 **%logon**::
 
 	Restart logging.
 
         This function is for restarting logging which you've temporarily
         stopped with %logoff. For starting logging for the first time, you
         must use the %logstart function, which allows you to specify an
         optional log filename.
 
 **%logstart**::
 
 	Start logging anywhere in a session.
 
         %logstart [-o|-r|-t] [log_name [log_mode]]
 
         If no name is given, it defaults to a file named 'ipython_log.py' in your
         current directory, in 'rotate' mode (see below).
 
         '%logstart name' saves to file 'name' in 'backup' mode.  It saves your
         history up to that point and then continues logging.
 
         %logstart takes a second optional parameter: logging mode. This can be one
         of (note that the modes are given unquoted):\
           append: well, that says it.\
           backup: rename (if exists) to name~ and start name.\
           global: single logfile in your home dir, appended to.\
           over  : overwrite existing log.\
           rotate: create rotating logs name.1~, name.2~, etc.
 
         Options:
 
           -o: log also IPython's output.  In this mode, all commands which
           generate an Out[NN] prompt are recorded to the logfile, right after
           their corresponding input line.  The output lines are always
           prepended with a '#[Out]# ' marker, so that the log remains valid
           Python code.
 
           Since this marker is always the same, filtering only the output from
           a log is very easy, using for example a simple awk call:
 
             awk -F'#\[Out\]# ' '{if($2) {print $2}}' ipython_log.py
 
           -r: log 'raw' input.  Normally, IPython's logs contain the processed
           input, so that user lines are logged in their final form, converted
           into valid Python.  For example, %Exit is logged as
           '_ip.magic("Exit").  If the -r flag is given, all input is logged
           exactly as typed, with no transformations applied.
 
           -t: put timestamps before each input line logged (these are put in
           comments).
 
 **%logstate**::
 
 	Print the status of the logging system.
 
 **%logstop**::
 
 	Fully stop logging and close log file.
 
         In order to start logging again, a new %logstart call needs to be made,
         possibly (though not necessarily) with a new filename, mode and other
         options.
 
 **%lsmagic**::
 
 	List currently available magic functions.
 
 **%macro**::
 
 	Define a set of input lines as a macro for future re-execution.
 
         Usage:\
           %macro [options] name n1-n2 n3-n4 ... n5 .. n6 ...
 
         Options:
         
           -r: use 'raw' input.  By default, the 'processed' history is used,
           so that magics are loaded in their transformed version to valid
           Python.  If this option is given, the raw input as typed as the
           command line is used instead.
 
         This will define a global variable called `name` which is a string
         made of joining the slices and lines you specify (n1,n2,... numbers
         above) from your input history into a single string. This variable
         acts like an automatic function which re-executes those lines as if
         you had typed them. You just type 'name' at the prompt and the code
         executes.
 
         The notation for indicating number ranges is: n1-n2 means 'use line
         numbers n1,...n2' (the endpoint is included).  That is, '5-7' means
         using the lines numbered 5,6 and 7.
 
         Note: as a 'hidden' feature, you can also use traditional python slice
         notation, where N:M means numbers N through M-1.
 
         For example, if your history contains (%hist prints it):
         
           44: x=1\
           45: y=3\
           46: z=x+y\
           47: print x\
           48: a=5\
           49: print 'x',x,'y',y\
 
         you can create a macro with lines 44 through 47 (included) and line 49
         called my_macro with:
 
           In [51]: %macro my_macro 44-47 49
 
         Now, typing `my_macro` (without quotes) will re-execute all this code
         in one pass.
 
         You don't need to give the line-numbers in order, and any given line
         number can appear multiple times. You can assemble macros with any
         lines from your input history in any order.
 
         The macro is a simple object which holds its value in an attribute,
         but IPython's display system checks for macros and executes them as
         code instead of printing them when you type their name.
 
         You can view a macro's contents by explicitly printing it with:
         
           'print macro_name'.
 
         For one-off cases which DON'T contain magic function calls in them you
         can obtain similar results by explicitly executing slices from your
         input history with:
 
           In [60]: exec In[44:48]+In[49]
 
 **%magic**::
 
 	Print information about the magic function system.
 
 **%mglob**::
 
 	    This program allows specifying filenames with "mglob" mechanism.
     Supported syntax in globs (wilcard matching patterns)::
     
      *.cpp ?ellowo*                
          - obvious. Differs from normal glob in that dirs are not included.
            Unix users might want to write this as: "*.cpp" "?ellowo*"
      rec:/usr/share=*.txt,*.doc    
          - get all *.txt and *.doc under /usr/share, 
            recursively
      rec:/usr/share
          - All files under /usr/share, recursively
      rec:*.py
          - All .py files under current working dir, recursively
      foo                           
          - File or dir foo
      !*.bak readme*                   
          - readme*, exclude files ending with .bak
      !.svn/ !.hg/ !*_Data/ rec:.
          - Skip .svn, .hg, foo_Data dirs (and their subdirs) in recurse.
            Trailing / is the key, \ does not work!
      dir:foo                       
          - the directory foo if it exists (not files in foo)
      dir:*                         
          - all directories in current folder
      foo.py bar.* !h* rec:*.py
          - Obvious. !h* exclusion only applies for rec:*.py.
            foo.py is *not* included twice.
      @filelist.txt
          - All files listed in 'filelist.txt' file, on separate lines.
 
 **%page**::
 
 	Pretty print the object and display it through a pager.
         
         %page [options] OBJECT
 
         If no object is given, use _ (last output).
         
         Options:
 
           -r: page str(object), don't pretty-print it.
 
 **%pdb**::
 
 	Control the automatic calling of the pdb interactive debugger.
 
         Call as '%pdb on', '%pdb 1', '%pdb off' or '%pdb 0'. If called without
         argument it works as a toggle.
 
         When an exception is triggered, IPython can optionally call the
         interactive pdb debugger after the traceback printout. %pdb toggles
         this feature on and off.
 
         The initial state of this feature is set in your ipythonrc
         configuration file (the variable is called 'pdb').
 
         If you want to just activate the debugger AFTER an exception has fired,
         without having to type '%pdb on' and rerunning your code, you can use
         the %debug magic.
 
 **%pdef**::
 
 	Print the definition header for any callable object.
 
         If the object is a class, print the constructor information.
 
 **%pdoc**::
 
 	Print the docstring for an object.
 
         If the given object is a class, it will print both the class and the
         constructor docstrings.
 
 **%pfile**::
 
 	Print (or run through pager) the file where an object is defined.
 
         The file opens at the line where the object definition begins. IPython
         will honor the environment variable PAGER if set, and otherwise will
         do its best to print the file in a convenient form.
 
         If the given argument is not an object currently defined, IPython will
         try to interpret it as a filename (automatically adding a .py extension
         if needed). You can thus use %pfile as a syntax highlighting code
         viewer.
 
 **%pinfo**::
 
 	Provide detailed information about an object.
     
         '%pinfo object' is just a synonym for object? or ?object.
 
 **%popd**::
 
 	Change to directory popped off the top of the stack.
 
 **%profile**::
 
 	Print your currently active IPyhton profile.
 
 **%prun**::
 
 	Run a statement through the python code profiler.
 
         Usage:\
           %prun [options] statement
 
         The given statement (which doesn't require quote marks) is run via the
         python profiler in a manner similar to the profile.run() function.
         Namespaces are internally managed to work correctly; profile.run
         cannot be used in IPython because it makes certain assumptions about
         namespaces which do not hold under IPython.
 
         Options:
 
         -l <limit>: you can place restrictions on what or how much of the
         profile gets printed. The limit value can be:
 
           * A string: only information for function names containing this string
           is printed.
 
           * An integer: only these many lines are printed.
 
           * A float (between 0 and 1): this fraction of the report is printed
           (for example, use a limit of 0.4 to see the topmost 40% only).
 
         You can combine several limits with repeated use of the option. For
         example, '-l __init__ -l 5' will print only the topmost 5 lines of
         information about class constructors.
 
         -r: return the pstats.Stats object generated by the profiling. This
         object has all the information about the profile in it, and you can
         later use it for further analysis or in other functions.
 
        -s <key>: sort profile by given key. You can provide more than one key
         by using the option several times: '-s key1 -s key2 -s key3...'. The
         default sorting key is 'time'.
 
         The following is copied verbatim from the profile documentation
         referenced below:
 
         When more than one key is provided, additional keys are used as
         secondary criteria when the there is equality in all keys selected
         before them.
         
         Abbreviations can be used for any key names, as long as the
         abbreviation is unambiguous.  The following are the keys currently
         defined:
 
                 Valid Arg       Meaning\
                   "calls"      call count\
                   "cumulative" cumulative time\
                   "file"       file name\
                   "module"     file name\
                   "pcalls"     primitive call count\
                   "line"       line number\
                   "name"       function name\
                   "nfl"        name/file/line\
                   "stdname"    standard name\
                   "time"       internal time
 
         Note that all sorts on statistics are in descending order (placing
         most time consuming items first), where as name, file, and line number
         searches are in ascending order (i.e., alphabetical). The subtle
         distinction between "nfl" and "stdname" is that the standard name is a
         sort of the name as printed, which means that the embedded line
         numbers get compared in an odd way.  For example, lines 3, 20, and 40
         would (if the file names were the same) appear in the string order
         "20" "3" and "40".  In contrast, "nfl" does a numeric compare of the
         line numbers.  In fact, sort_stats("nfl") is the same as
         sort_stats("name", "file", "line").
 
         -T <filename>: save profile results as shown on screen to a text
         file. The profile is still shown on screen.
 
         -D <filename>: save (via dump_stats) profile statistics to given
         filename. This data is in a format understod by the pstats module, and
         is generated by a call to the dump_stats() method of profile
         objects. The profile is still shown on screen.
 
         If you want to run complete programs under the profiler's control, use
         '%run -p [prof_opts] filename.py [args to program]' where prof_opts
         contains profiler specific options as described here.
         
         You can read the complete documentation for the profile module with:\
           In [1]: import profile; profile.help()
 
 **%psearch**::
 
 	Search for object in namespaces by wildcard.
 
         %psearch [options] PATTERN [OBJECT TYPE]
 
         Note: ? can be used as a synonym for %psearch, at the beginning or at
         the end: both a*? and ?a* are equivalent to '%psearch a*'.  Still, the
         rest of the command line must be unchanged (options come first), so
         for example the following forms are equivalent
 
         %psearch -i a* function
         -i a* function?
         ?-i a* function
 
         Arguments:
         
           PATTERN
 
           where PATTERN is a string containing * as a wildcard similar to its
           use in a shell.  The pattern is matched in all namespaces on the
           search path. By default objects starting with a single _ are not
           matched, many IPython generated objects have a single
           underscore. The default is case insensitive matching. Matching is
           also done on the attributes of objects and not only on the objects
           in a module.
 
           [OBJECT TYPE]
 
           Is the name of a python type from the types module. The name is
           given in lowercase without the ending type, ex. StringType is
           written string. By adding a type here only objects matching the
           given type are matched. Using all here makes the pattern match all
           types (this is the default).
 
         Options:
 
           -a: makes the pattern match even objects whose names start with a
           single underscore.  These names are normally ommitted from the
           search.
 
           -i/-c: make the pattern case insensitive/sensitive.  If neither of
           these options is given, the default is read from your ipythonrc
           file.  The option name which sets this value is
           'wildcards_case_sensitive'.  If this option is not specified in your
           ipythonrc file, IPython's internal default is to do a case sensitive
           search.
 
           -e/-s NAMESPACE: exclude/search a given namespace.  The pattern you
           specifiy can be searched in any of the following namespaces:
           'builtin', 'user', 'user_global','internal', 'alias', where
           'builtin' and 'user' are the search defaults.  Note that you should
           not use quotes when specifying namespaces.
 
           'Builtin' contains the python module builtin, 'user' contains all
           user data, 'alias' only contain the shell aliases and no python
           objects, 'internal' contains objects used by IPython.  The
           'user_global' namespace is only used by embedded IPython instances,
           and it contains module-level globals.  You can add namespaces to the
           search with -s or exclude them with -e (these options can be given
           more than once).
     
         Examples:
        
         %psearch a*            -> objects beginning with an a
         %psearch -e builtin a* -> objects NOT in the builtin space starting in a
         %psearch a* function   -> all functions beginning with an a
         %psearch re.e*         -> objects beginning with an e in module re
         %psearch r*.e*         -> objects that start with e in modules starting in r
         %psearch r*.* string   -> all strings in modules beginning with r
 
         Case sensitve search:
        
         %psearch -c a*         list all object beginning with lower case a
 
         Show objects beginning with a single _:
        
         %psearch -a _*         list objects beginning with a single underscore
 
 **%psource**::
 
 	Print (or run through pager) the source code for an object.
 
 **%pushd**::
 
 	Place the current dir on stack and change directory.
         
         Usage:\
           %pushd ['dirname']
 
 **%pwd**::
 
 	Return the current working directory path.
 
 **%pycat**::
 
 	Show a syntax-highlighted file through a pager.
 
         This magic is similar to the cat utility, but it will assume the file
         to be Python source and will show it with syntax highlighting.
 
 **%quickref**::
 
 	 Show a quick reference sheet
 
 **%quit**::
 
 	Exit IPython, confirming if configured to do so (like %exit)
 
 **%r**::
 
 	Repeat previous input.
 
         Note: Consider using the more powerfull %rep instead!
         
         If given an argument, repeats the previous command which starts with
         the same string, otherwise it just repeats the previous input.
 
         Shell escaped commands (with ! as first character) are not recognized
         by this system, only pure python code and magic commands.
 
 **%rehashdir**::
 
 	 Add executables in all specified dirs to alias table
      
     Usage:
 
     %rehashdir c:/bin;c:/tools
       - Add all executables under c:/bin and c:/tools to alias table, in 
       order to make them directly executable from any directory.
         
       Without arguments, add all executables in current directory.
 
 **%rehashx**::
 
 	Update the alias table with all executable files in $PATH.
 
         This version explicitly checks that every entry in $PATH is a file
         with execute access (os.X_OK), so it is much slower than %rehash.
 
         Under Windows, it checks executability as a match agains a
         '|'-separated string of extensions, stored in the IPython config
         variable win_exec_ext.  This defaults to 'exe|com|bat'.
         
         This function also resets the root module cache of module completer,
         used on slow filesystems.
 
 **%rep**::
 
 	 Repeat a command, or get command to input line for editing
 
     - %rep (no arguments):
     
     Place a string version of last computation result (stored in the special '_'
     variable) to the next input prompt. Allows you to create elaborate command
     lines without using copy-paste::
     
         $ l = ["hei", "vaan"]       
         $ "".join(l)        
         ==> heivaan        
         $ %rep        
         $ heivaan_ <== cursor blinking    
     
     %rep 45
     
     Place history line 45 to next input prompt. Use %hist to find out the
     number.
     
     %rep 1-4 6-7 3
     
     Repeat the specified lines immediately. Input slice syntax is the same as
     in %macro and %save.
     
     %rep foo
     
     Place the most recent line that has the substring "foo" to next input.
     (e.g. 'svn ci -m foobar').
 
 **%reset**::
 
 	Resets the namespace by removing all names defined by the user.
 
         Input/Output history are left around in case you need them.
 
 **%run**::
 
 	Run the named file inside IPython as a program.
 
         Usage:\
           %run [-n -i -t [-N<N>] -d [-b<N>] -p [profile options]] file [args]
         
         Parameters after the filename are passed as command-line arguments to
         the program (put in sys.argv). Then, control returns to IPython's
         prompt.
 
         This is similar to running at a system prompt:\
           $ python file args\
         but with the advantage of giving you IPython's tracebacks, and of
         loading all variables into your interactive namespace for further use
         (unless -p is used, see below).
 
         The file is executed in a namespace initially consisting only of
         __name__=='__main__' and sys.argv constructed as indicated. It thus
         sees its environment as if it were being run as a stand-alone program
         (except for sharing global objects such as previously imported
         modules). But after execution, the IPython interactive namespace gets
         updated with all variables defined in the program (except for __name__
         and sys.argv). This allows for very convenient loading of code for
         interactive work, while giving each program a 'clean sheet' to run in.
 
         Options:
         
         -n: __name__ is NOT set to '__main__', but to the running file's name
         without extension (as python does under import).  This allows running
         scripts and reloading the definitions in them without calling code
         protected by an ' if __name__ == "__main__" ' clause.
 
         -i: run the file in IPython's namespace instead of an empty one. This
         is useful if you are experimenting with code written in a text editor
         which depends on variables defined interactively.
 
         -e: ignore sys.exit() calls or SystemExit exceptions in the script
         being run.  This is particularly useful if IPython is being used to
         run unittests, which always exit with a sys.exit() call.  In such
         cases you are interested in the output of the test results, not in
         seeing a traceback of the unittest module.
 
         -t: print timing information at the end of the run.  IPython will give
         you an estimated CPU time consumption for your script, which under
         Unix uses the resource module to avoid the wraparound problems of
         time.clock().  Under Unix, an estimate of time spent on system tasks
         is also given (for Windows platforms this is reported as 0.0).
 
         If -t is given, an additional -N<N> option can be given, where <N>
         must be an integer indicating how many times you want the script to
         run.  The final timing report will include total and per run results.
 
         For example (testing the script uniq_stable.py):
 
             In [1]: run -t uniq_stable
 
             IPython CPU timings (estimated):\
               User  :    0.19597 s.\
               System:        0.0 s.\
 
             In [2]: run -t -N5 uniq_stable
 
             IPython CPU timings (estimated):\
             Total runs performed: 5\
               Times :      Total       Per run\
               User  :   0.910862 s,  0.1821724 s.\
               System:        0.0 s,        0.0 s.
 
         -d: run your program under the control of pdb, the Python debugger.
         This allows you to execute your program step by step, watch variables,
         etc.  Internally, what IPython does is similar to calling:
         
           pdb.run('execfile("YOURFILENAME")')
 
         with a breakpoint set on line 1 of your file.  You can change the line
         number for this automatic breakpoint to be <N> by using the -bN option
         (where N must be an integer).  For example:
 
           %run -d -b40 myscript
 
         will set the first breakpoint at line 40 in myscript.py.  Note that
         the first breakpoint must be set on a line which actually does
         something (not a comment or docstring) for it to stop execution.
 
         When the pdb debugger starts, you will see a (Pdb) prompt.  You must
         first enter 'c' (without qoutes) to start execution up to the first
         breakpoint.
 
         Entering 'help' gives information about the use of the debugger.  You
         can easily see pdb's full documentation with "import pdb;pdb.help()"
         at a prompt.
 
         -p: run program under the control of the Python profiler module (which
         prints a detailed report of execution times, function calls, etc).
 
         You can pass other options after -p which affect the behavior of the
         profiler itself. See the docs for %prun for details.
 
         In this mode, the program's variables do NOT propagate back to the
         IPython interactive namespace (because they remain in the namespace
         where the profiler executes them).
 
         Internally this triggers a call to %prun, see its documentation for
         details on the options available specifically for profiling.
 
         There is one special usage for which the text above doesn't apply:
         if the filename ends with .ipy, the file is run as ipython script,
         just as if the commands were written on IPython prompt.
 
 **%runlog**::
 
 	Run files as logs.
 
         Usage:\
           %runlog file1 file2 ...
 
         Run the named files (treating them as log files) in sequence inside
         the interpreter, and return to the prompt.  This is much slower than
         %run because each line is executed in a try/except block, but it
         allows running files with syntax errors in them.
 
         Normally IPython will guess when a file is one of its own logfiles, so
         you can typically use %run even for logs. This shorthand allows you to
         force any file to be treated as a log file.
 
 **%save**::
 
 	Save a set of lines to a given filename.
 
         Usage:\
           %save [options] filename n1-n2 n3-n4 ... n5 .. n6 ...
 
         Options:
         
           -r: use 'raw' input.  By default, the 'processed' history is used,
           so that magics are loaded in their transformed version to valid
           Python.  If this option is given, the raw input as typed as the
           command line is used instead.
 
         This function uses the same syntax as %macro for line extraction, but
         instead of creating a macro it saves the resulting string to the
         filename you specify.
 
         It adds a '.py' extension to the file if you don't do so yourself, and
         it asks for confirmation before overwriting existing files.
 
 **%sc**::
 
 	Shell capture - execute a shell command and capture its output.
 
         DEPRECATED. Suboptimal, retained for backwards compatibility.
         
         You should use the form 'var = !command' instead. Example:
          
          "%sc -l myfiles = ls ~" should now be written as
             
          "myfiles = !ls ~"
          
         myfiles.s, myfiles.l and myfiles.n still apply as documented
         below.
 
         --
         %sc [options] varname=command
 
         IPython will run the given command using commands.getoutput(), and
         will then update the user's interactive namespace with a variable
         called varname, containing the value of the call.  Your command can
         contain shell wildcards, pipes, etc.
 
         The '=' sign in the syntax is mandatory, and the variable name you
         supply must follow Python's standard conventions for valid names.
         
         (A special format without variable name exists for internal use)
 
         Options:
 
           -l: list output.  Split the output on newlines into a list before
           assigning it to the given variable.  By default the output is stored
           as a single string.
 
           -v: verbose.  Print the contents of the variable.
 
         In most cases you should not need to split as a list, because the
         returned value is a special type of string which can automatically
         provide its contents either as a list (split on newlines) or as a
         space-separated string.  These are convenient, respectively, either
         for sequential processing or to be passed to a shell command.
 
         For example:
 
             # Capture into variable a
             In [9]: sc a=ls *py
 
             # a is a string with embedded newlines
             In [10]: a
             Out[10]: 'setup.py win32_manual_post_install.py'
 
             # which can be seen as a list:
             In [11]: a.l
             Out[11]: ['setup.py', 'win32_manual_post_install.py']
 
             # or as a whitespace-separated string:
             In [12]: a.s
             Out[12]: 'setup.py win32_manual_post_install.py'
 
             # a.s is useful to pass as a single command line:
             In [13]: !wc -l $a.s
               146 setup.py
               130 win32_manual_post_install.py
               276 total
 
             # while the list form is useful to loop over:
             In [14]: for f in a.l:
                ....:      !wc -l $f
                ....:
             146 setup.py
             130 win32_manual_post_install.py
 
         Similiarly, the lists returned by the -l option are also special, in
         the sense that you can equally invoke the .s attribute on them to
         automatically get a whitespace-separated string from their contents:
 
             In [1]: sc -l b=ls *py
 
             In [2]: b
             Out[2]: ['setup.py', 'win32_manual_post_install.py']
 
             In [3]: b.s
             Out[3]: 'setup.py win32_manual_post_install.py'
 
         In summary, both the lists and strings used for ouptut capture have
         the following special attributes:
 
             .l (or .list) : value as list.
             .n (or .nlstr): value as newline-separated string.
             .s (or .spstr): value as space-separated string.
 
 **%store**::
 
 	Lightweight persistence for python variables.
 
     Example:
     
     ville@badger[~]|1> A = ['hello',10,'world']\
     ville@badger[~]|2> %store A\
     ville@badger[~]|3> Exit
     
     (IPython session is closed and started again...)
     
     ville@badger:~$ ipython -p pysh\
     ville@badger[~]|1> print A
     
     ['hello', 10, 'world']
     
     Usage:
     
     %store          - Show list of all variables and their current values\
     %store <var>    - Store the *current* value of the variable to disk\
     %store -d <var> - Remove the variable and its value from storage\
     %store -z       - Remove all variables from storage\
     %store -r       - Refresh all variables from store (delete current vals)\
     %store foo >a.txt  - Store value of foo to new file a.txt\
     %store foo >>a.txt - Append value of foo to file a.txt\   
     
     It should be noted that if you change the value of a variable, you
     need to %store it again if you want to persist the new value.
     
     Note also that the variables will need to be pickleable; most basic
     python types can be safely %stored.
     
     Also aliases can be %store'd across sessions.
 
 **%sx**::
 
 	Shell execute - run a shell command and capture its output.
 
         %sx command
 
         IPython will run the given command using commands.getoutput(), and
         return the result formatted as a list (split on '\n').  Since the
         output is _returned_, it will be stored in ipython's regular output
         cache Out[N] and in the '_N' automatic variables.
 
         Notes:
 
         1) If an input line begins with '!!', then %sx is automatically
         invoked.  That is, while:
           !ls
         causes ipython to simply issue system('ls'), typing
           !!ls
         is a shorthand equivalent to:
           %sx ls
         
         2) %sx differs from %sc in that %sx automatically splits into a list,
         like '%sc -l'.  The reason for this is to make it as easy as possible
         to process line-oriented shell output via further python commands.
         %sc is meant to provide much finer control, but requires more
         typing.
 
         3) Just like %sc -l, this is a list with special attributes:
 
           .l (or .list) : value as list.
           .n (or .nlstr): value as newline-separated string.
           .s (or .spstr): value as whitespace-separated string.
 
         This is very useful when trying to use such lists as arguments to
         system commands.
 
 **%system_verbose**::
 
 	Set verbose printing of system calls.
 
         If called without an argument, act as a toggle
 
 **%time**::
 
 	Time execution of a Python statement or expression.
 
         The CPU and wall clock times are printed, and the value of the
         expression (if any) is returned.  Note that under Win32, system time
         is always reported as 0, since it can not be measured.
 
         This function provides very basic timing functionality.  In Python
         2.3, the timeit module offers more control and sophistication, so this
         could be rewritten to use it (patches welcome).
         
         Some examples:
 
           In [1]: time 2**128
           CPU times: user 0.00 s, sys: 0.00 s, total: 0.00 s
           Wall time: 0.00
           Out[1]: 340282366920938463463374607431768211456L
 
           In [2]: n = 1000000
 
           In [3]: time sum(range(n))
           CPU times: user 1.20 s, sys: 0.05 s, total: 1.25 s
           Wall time: 1.37
           Out[3]: 499999500000L
 
           In [4]: time print 'hello world'
           hello world
           CPU times: user 0.00 s, sys: 0.00 s, total: 0.00 s
           Wall time: 0.00
 
           Note that the time needed by Python to compile the given expression
           will be reported if it is more than 0.1s.  In this example, the
           actual exponentiation is done by Python at compilation time, so while
           the expression can take a noticeable amount of time to compute, that
           time is purely due to the compilation:
 
           In [5]: time 3**9999;
           CPU times: user 0.00 s, sys: 0.00 s, total: 0.00 s
           Wall time: 0.00 s
 
           In [6]: time 3**999999;
           CPU times: user 0.00 s, sys: 0.00 s, total: 0.00 s
           Wall time: 0.00 s
           Compiler : 0.78 s
 
 **%timeit**::
 
 	Time execution of a Python statement or expression
 
         Usage:\
           %timeit [-n<N> -r<R> [-t|-c]] statement
 
         Time execution of a Python statement or expression using the timeit
         module.
 
         Options:
         -n<N>: execute the given statement <N> times in a loop. If this value
         is not given, a fitting value is chosen. 
         
         -r<R>: repeat the loop iteration <R> times and take the best result.
         Default: 3
         
         -t: use time.time to measure the time, which is the default on Unix.
         This function measures wall time.
         
         -c: use time.clock to measure the time, which is the default on
         Windows and measures wall time. On Unix, resource.getrusage is used
         instead and returns the CPU user time.
 
         -p<P>: use a precision of <P> digits to display the timing result.
         Default: 3
 
         
         Examples:\
           In [1]: %timeit pass
           10000000 loops, best of 3: 53.3 ns per loop
 
           In [2]: u = None
 
           In [3]: %timeit u is None
           10000000 loops, best of 3: 184 ns per loop
 
           In [4]: %timeit -r 4 u == None
           1000000 loops, best of 4: 242 ns per loop
 
           In [5]: import time
 
           In [6]: %timeit -n1 time.sleep(2)
           1 loops, best of 3: 2 s per loop
           
 
         The times reported by %timeit will be slightly higher than those
         reported by the timeit.py script when variables are accessed. This is
         due to the fact that %timeit executes the statement in the namespace
         of the shell, compared with timeit.py, which uses a single setup
         statement to import function or create variables. Generally, the bias
         does not matter as long as results from timeit.py are not mixed with
         those from %timeit.
 
 **%unalias**::
 
 	Remove an alias
 
 **%upgrade**::
 
 	 Upgrade your IPython installation
         
         This will copy the config files that don't yet exist in your 
         ipython dir from the system config dir. Use this after upgrading 
         IPython if you don't wish to delete your .ipython dir.
 
         Call with -nolegacy to get rid of ipythonrc* files (recommended for
         new users)
 
 **%which**::
 
 	 %which <cmd> => search PATH for files matching cmd. Also scans aliases.
 
     Traverses PATH and prints all files (not just executables!) that match the
     pattern on command line. Probably more useful in finding stuff
     interactively than 'which', which only prints the first matching item.
     
     Also discovers and expands aliases, so you'll see what will be executed
     when you call an alias.
     
     Example:
     
     [~]|62> %which d
     d -> ls -F --color=auto
       == c:\cygwin\bin\ls.exe
     c:\cygwin\bin\d.exe
     
     [~]|64> %which diff*
     diff3 -> diff3
       == c:\cygwin\bin\diff3.exe
     diff -> diff
       == c:\cygwin\bin\diff.exe
     c:\cygwin\bin\diff.exe
     c:\cygwin\bin\diff3.exe
 
 **%who**::
 
 	Print all interactive variables, with some minimal formatting.
 
         If any arguments are given, only variables whose type matches one of
         these are printed.  For example:
 
           %who function str
 
         will only list functions and strings, excluding all other types of
         variables.  To find the proper type names, simply use type(var) at a
         command line to see how python prints type names.  For example:
 
           In [1]: type('hello')\
           Out[1]: <type 'str'>
 
         indicates that the type name for strings is 'str'.
 
         %who always excludes executed names loaded through your configuration
         file and things which are internal to IPython.
 
         This is deliberate, as typically you may load many modules and the
         purpose of %who is to show you only what you've manually defined.
 
 **%who_ls**::
 
 	Return a sorted list of all interactive variables.
 
         If arguments are given, only variables of types matching these
         arguments are returned.
 
 **%whos**::
 
 	Like %who, but gives some extra information about each variable.
 
         The same type filtering of %who can be applied here.
 
         For all variables, the type is printed. Additionally it prints:
         
           - For {},[],(): their length.
 
           - For numpy and Numeric arrays, a summary with shape, number of
           elements, typecode and size in memory.
 
           - Everything else: a string representation, snipping their middle if
           too long.
 
 **%xmode**::
 
 	Switch modes for the exception handlers.
 
         Valid modes: Plain, Context and Verbose.
 
         If called without arguments, acts as a toggle.
 
 .. magic_end
 
 Access to the standard Python help
 ----------------------------------
 
 As of Python 2.1, a help system is available with access to object
 docstrings and the Python manuals. Simply type 'help' (no quotes) to
 access it. You can also type help(object) to obtain information about a
 given object, and help('keyword') for information on a keyword. As noted
 in sec. `accessing help`_, you need to properly configure
 your environment variable PYTHONDOCS for this feature to work correctly.
 
 
 Dynamic object information
 --------------------------
 
 Typing ?word or word? prints detailed information about an object. If
 certain strings in the object are too long (docstrings, code, etc.) they
 get snipped in the center for brevity. This system gives access variable
 types and values, full source code for any object (if available),
 function prototypes and other useful information.
 
 Typing ??word or word?? gives access to the full information without
 snipping long strings. Long strings are sent to the screen through the
 less pager if longer than the screen and printed otherwise. On systems
 lacking the less command, IPython uses a very basic internal pager.
 
 The following magic functions are particularly useful for gathering
 information about your working environment. You can get more details by
 typing %magic or querying them individually (use %function_name? with or
 without the %), this is just a summary:
 
     * **%pdoc <object>**: Print (or run through a pager if too long) the
       docstring for an object. If the given object is a class, it will
       print both the class and the constructor docstrings.
     * **%pdef <object>**: Print the definition header for any callable
       object. If the object is a class, print the constructor information.
     * **%psource <object>**: Print (or run through a pager if too long)
       the source code for an object.
     * **%pfile <object>**: Show the entire source file where an object was
       defined via a pager, opening it at the line where the object
       definition begins.
     * **%who/%whos**: These functions give information about identifiers
       you have defined interactively (not things you loaded or defined
       in your configuration files). %who just prints a list of
       identifiers and %whos prints a table with some basic details about
       each identifier.
 
 Note that the dynamic object information functions (?/??, %pdoc, %pfile,
 %pdef, %psource) give you access to documentation even on things which
 are not really defined as separate identifiers. Try for example typing
 {}.get? or after doing import os, type os.path.abspath??.
 
 
 .. _Readline:
 
 Readline-based features
 -----------------------
 
 These features require the GNU readline library, so they won't work if
 your Python installation lacks readline support. We will first describe
 the default behavior IPython uses, and then how to change it to suit
 your preferences.
 
 
 Command line completion
 +++++++++++++++++++++++
 
 At any time, hitting TAB will complete any available python commands or
 variable names, and show you a list of the possible completions if
 there's no unambiguous one. It will also complete filenames in the
 current directory if no python names match what you've typed so far.
 
 
 Search command history
 ++++++++++++++++++++++
 
 IPython provides two ways for searching through previous input and thus
 reduce the need for repetitive typing:
 
    1. Start typing, and then use Ctrl-p (previous,up) and Ctrl-n
       (next,down) to search through only the history items that match
       what you've typed so far. If you use Ctrl-p/Ctrl-n at a blank
       prompt, they just behave like normal arrow keys.
    2. Hit Ctrl-r: opens a search prompt. Begin typing and the system
       searches your history for lines that contain what you've typed so
       far, completing as much as it can.
 
 
 Persistent command history across sessions
 ++++++++++++++++++++++++++++++++++++++++++
 
 IPython will save your input history when it leaves and reload it next
 time you restart it. By default, the history file is named
 $IPYTHONDIR/history, but if you've loaded a named profile,
 '-PROFILE_NAME' is appended to the name. This allows you to keep
 separate histories related to various tasks: commands related to
 numerical work will not be clobbered by a system shell history, for
 example.
 
 
 Autoindent
 ++++++++++
 
 IPython can recognize lines ending in ':' and indent the next line,
 while also un-indenting automatically after 'raise' or 'return'.
 
 This feature uses the readline library, so it will honor your ~/.inputrc
 configuration (or whatever file your INPUTRC variable points to). Adding
 the following lines to your .inputrc file can make indenting/unindenting
 more convenient (M-i indents, M-u unindents)::
 
     $if Python 
     "\M-i": "    "  
     "\M-u": "\d\d\d\d"  
     $endif
 
 Note that there are 4 spaces between the quote marks after "M-i" above.
 
 Warning: this feature is ON by default, but it can cause problems with
 the pasting of multi-line indented code (the pasted code gets
 re-indented on each line). A magic function %autoindent allows you to
 toggle it on/off at runtime. You can also disable it permanently on in
 your ipythonrc file (set autoindent 0).
 
 
 Customizing readline behavior
 +++++++++++++++++++++++++++++
 
 All these features are based on the GNU readline library, which has an
 extremely customizable interface. Normally, readline is configured via a
 file which defines the behavior of the library; the details of the
 syntax for this can be found in the readline documentation available
 with your system or on the Internet. IPython doesn't read this file (if
 it exists) directly, but it does support passing to readline valid
 options via a simple interface. In brief, you can customize readline by
 setting the following options in your ipythonrc configuration file (note
 that these options can not be specified at the command line):
 
     * **readline_parse_and_bind**: this option can appear as many times as
       you want, each time defining a string to be executed via a
       readline.parse_and_bind() command. The syntax for valid commands
       of this kind can be found by reading the documentation for the GNU
       readline library, as these commands are of the kind which readline
       accepts in its configuration file.
     * **readline_remove_delims**: a string of characters to be removed
       from the default word-delimiters list used by readline, so that
       completions may be performed on strings which contain them. Do not
       change the default value unless you know what you're doing.
     * **readline_omit__names**: when tab-completion is enabled, hitting
       <tab> after a '.' in a name will complete all attributes of an
       object, including all the special methods whose names include
       double underscores (like __getitem__ or __class__). If you'd
       rather not see these names by default, you can set this option to
       1. Note that even when this option is set, you can still see those
       names by explicitly typing a _ after the period and hitting <tab>:
       'name._<tab>' will always complete attribute names starting with '_'.
       
       This option is off by default so that new users see all
       attributes of any objects they are dealing with.
 
 You will find the default values along with a corresponding detailed
 explanation in your ipythonrc file.
 
 
 Session logging and restoring
 -----------------------------
 
 You can log all input from a session either by starting IPython with
 the command line switches -log or -logfile (see sec. `command line
 options`_) or by activating the logging at any moment with the magic
 function %logstart.
 
 Log files can later be reloaded with the -logplay option and IPython
 will attempt to 'replay' the log by executing all the lines in it, thus
 restoring the state of a previous session. This feature is not quite
 perfect, but can still be useful in many cases.
 
 The log files can also be used as a way to have a permanent record of
 any code you wrote while experimenting. Log files are regular text files
 which you can later open in your favorite text editor to extract code or
 to 'clean them up' before using them to replay a session.
 
 The %logstart function for activating logging in mid-session is used as
 follows:
 
 %logstart [log_name [log_mode]]
 
 If no name is given, it defaults to a file named 'log' in your
 IPYTHONDIR directory, in 'rotate' mode (see below).
 
 '%logstart name' saves to file 'name' in 'backup' mode. It saves your
 history up to that point and then continues logging.
 
 %logstart takes a second optional parameter: logging mode. This can be
 one of (note that the modes are given unquoted):
 
     * [over:] overwrite existing log_name.
     * [backup:] rename (if exists) to log_name~ and start log_name.
     * [append:] well, that says it.
     * [rotate:] create rotating logs log_name.1~, log_name.2~, etc.
 
 The %logoff and %logon functions allow you to temporarily stop and
 resume logging to a file which had previously been started with
 %logstart. They will fail (with an explanation) if you try to use them
 before logging has been started.
 
 System shell access
 -------------------
 
 Any input line beginning with a ! character is passed verbatim (minus
 the !, of course) to the underlying operating system. For example,
 typing !ls will run 'ls' in the current directory.
 
 Manual capture of command output
 --------------------------------
 
 If the input line begins with two exclamation marks, !!, the command is
 executed but its output is captured and returned as a python list, split
 on newlines. Any output sent by the subprocess to standard error is
 printed separately, so that the resulting list only captures standard
 output. The !! syntax is a shorthand for the %sx magic command.
 
 Finally, the %sc magic (short for 'shell capture') is similar to %sx,
 but allowing more fine-grained control of the capture details, and
 storing the result directly into a named variable. The direct use of 
 %sc is now deprecated, and you should ise the ``var = !cmd`` syntax
 instead.
 
 IPython also allows you to expand the value of python variables when
 making system calls. Any python variable or expression which you prepend
 with $ will get expanded before the system call is made::
 
     In [1]: pyvar='Hello world' 
     In [2]: !echo "A python variable: $pyvar"  
     A python variable: Hello world
 
 If you want the shell to actually see a literal $, you need to type it
 twice::
 
     In [3]: !echo "A system variable: $$HOME"  
     A system variable: /home/fperez
 
 You can pass arbitrary expressions, though you'll need to delimit them
 with {} if there is ambiguity as to the extent of the expression::
 
     In [5]: x=10 
     In [6]: y=20 
     In [13]: !echo $x+y  
     10+y  
     In [7]: !echo ${x+y}  
     30
 
 Even object attributes can be expanded::
 
     In [12]: !echo $sys.argv  
     [/home/fperez/usr/bin/ipython]
 
 
 System command aliases
 ----------------------
 
 The %alias magic function and the alias option in the ipythonrc
 configuration file allow you to define magic functions which are in fact
 system shell commands. These aliases can have parameters.
 
 '%alias alias_name cmd' defines 'alias_name' as an alias for 'cmd'
 
 Then, typing '%alias_name params' will execute the system command 'cmd
 params' (from your underlying operating system).
 
 You can also define aliases with parameters using %s specifiers (one per
 parameter). The following example defines the %parts function as an
 alias to the command 'echo first %s second %s' where each %s will be
 replaced by a positional parameter to the call to %parts::
 
     In [1]: alias parts echo first %s second %s 
     In [2]: %parts A B 
     first A second B  
     In [3]: %parts A  
     Incorrect number of arguments: 2 expected.  
     parts is an alias to: 'echo first %s second %s'
 
 If called with no parameters, %alias prints the table of currently
 defined aliases.
 
 The %rehash/rehashx magics allow you to load your entire $PATH as
 ipython aliases. See their respective docstrings (or sec. 6.2
 <#sec:magic> for further details).
 
 
 .. _dreload:
 
 Recursive reload
 ----------------
 
 The dreload function does a recursive reload of a module: changes made
 to the module since you imported will actually be available without
 having to exit.
 
 
 Verbose and colored exception traceback printouts
 -------------------------------------------------
 
 IPython provides the option to see very detailed exception tracebacks,
 which can be especially useful when debugging large programs. You can
 run any Python file with the %run function to benefit from these
 detailed tracebacks. Furthermore, both normal and verbose tracebacks can
 be colored (if your terminal supports it) which makes them much easier
 to parse visually.
 
 See the magic xmode and colors functions for details (just type %magic).
 
 These features are basically a terminal version of Ka-Ping Yee's cgitb
 module, now part of the standard Python library.
 
 
 .. _Input caching:
 
 Input caching system
 --------------------
 
 IPython offers numbered prompts (In/Out) with input and output caching.
 All input is saved and can be retrieved as variables (besides the usual
 arrow key recall).
 
 The following GLOBAL variables always exist (so don't overwrite them!):
 _i: stores previous input. _ii: next previous. _iii: next-next previous.
 _ih : a list of all input _ih[n] is the input from line n and this list
 is aliased to the global variable In. If you overwrite In with a
 variable of your own, you can remake the assignment to the internal list
 with a simple 'In=_ih'.
 
 Additionally, global variables named _i<n> are dynamically created (<n>
 being the prompt counter), such that
 _i<n> == _ih[<n>] == In[<n>].
 
 For example, what you typed at prompt 14 is available as _i14, _ih[14]
 and In[14].
 
 This allows you to easily cut and paste multi line interactive prompts
 by printing them out: they print like a clean string, without prompt
 characters. You can also manipulate them like regular variables (they
 are strings), modify or exec them (typing 'exec _i9' will re-execute the
 contents of input prompt 9, 'exec In[9:14]+In[18]' will re-execute lines
 9 through 13 and line 18).
 
 You can also re-execute multiple lines of input easily by using the
 magic %macro function (which automates the process and allows
 re-execution without having to type 'exec' every time). The macro system
 also allows you to re-execute previous lines which include magic
 function calls (which require special processing). Type %macro? or see
 sec. 6.2 <#sec:magic> for more details on the macro system.
 
 A history function %hist allows you to see any part of your input
 history by printing a range of the _i variables.
 
 .. _Output caching:
 
 Output caching system
 ---------------------
 
 For output that is returned from actions, a system similar to the input
 cache exists but using _ instead of _i. Only actions that produce a
 result (NOT assignments, for example) are cached. If you are familiar
 with Mathematica, IPython's _ variables behave exactly like
 Mathematica's % variables.
 
 The following GLOBAL variables always exist (so don't overwrite them!):
 
     * [_] (a single underscore) : stores previous output, like Python's
       default interpreter.
     * [__] (two underscores): next previous.
     * [___] (three underscores): next-next previous.
 
 Additionally, global variables named _<n> are dynamically created (<n>
 being the prompt counter), such that the result of output <n> is always
 available as _<n> (don't use the angle brackets, just the number, e.g.
 _21).
 
 These global variables are all stored in a global dictionary (not a
 list, since it only has entries for lines which returned a result)
 available under the names _oh and Out (similar to _ih and In). So the
 output from line 12 can be obtained as _12, Out[12] or _oh[12]. If you
 accidentally overwrite the Out variable you can recover it by typing
 'Out=_oh' at the prompt.
 
 This system obviously can potentially put heavy memory demands on your
 system, since it prevents Python's garbage collector from removing any
 previously computed results. You can control how many results are kept
 in memory with the option (at the command line or in your ipythonrc
 file) cache_size. If you set it to 0, the whole system is completely
 disabled and the prompts revert to the classic '>>>' of normal Python.
 
 
 Directory history
 -----------------
 
 Your history of visited directories is kept in the global list _dh, and
 the magic %cd command can be used to go to any entry in that list. The
 %dhist command allows you to view this history. do ``cd -<TAB`` to
 conventiently view the directory history.
 
 
 Automatic parentheses and quotes
 --------------------------------
 
 These features were adapted from Nathan Gray's LazyPython. They are
 meant to allow less typing for common situations.
 
 
 Automatic parentheses
 ---------------------
 
 Callable objects (i.e. functions, methods, etc) can be invoked like this
 (notice the commas between the arguments)::
 
     >>> callable_ob arg1, arg2, arg3
 
 and the input will be translated to this::
 
     -> callable_ob(arg1, arg2, arg3)
 
 You can force automatic parentheses by using '/' as the first character
 of a line. For example::
 
     >>> /globals # becomes 'globals()'
 
 Note that the '/' MUST be the first character on the line! This won't work::
 
     >>> print /globals # syntax error
 
 In most cases the automatic algorithm should work, so you should rarely
 need to explicitly invoke /. One notable exception is if you are trying
 to call a function with a list of tuples as arguments (the parenthesis
 will confuse IPython)::
 
     In [1]: zip (1,2,3),(4,5,6) # won't work
 
 but this will work::
 
     In [2]: /zip (1,2,3),(4,5,6) 
     ---> zip ((1,2,3),(4,5,6))  
     Out[2]= [(1, 4), (2, 5), (3, 6)]
 
 IPython tells you that it has altered your command line by displaying
 the new command line preceded by ->. e.g.::
 
     In [18]: callable list 
     ----> callable (list)
 
 
 Automatic quoting
 -----------------
 
 You can force automatic quoting of a function's arguments by using ','
 or ';' as the first character of a line. For example::
 
     >>> ,my_function /home/me # becomes my_function("/home/me")
 
 If you use ';' instead, the whole argument is quoted as a single string
 (while ',' splits on whitespace)::
 
     >>> ,my_function a b c # becomes my_function("a","b","c")
 
     >>> ;my_function a b c # becomes my_function("a b c")
 
 Note that the ',' or ';' MUST be the first character on the line! This
 won't work::
 
     >>> x = ,my_function /home/me # syntax error
 
 .. customization:
 
 Customization
 =============
 
 There are 2 ways to configure IPython - the old way of using ipythonrc
 files (an INI-file like format), and the new way that involves editing
 your ipy_user_conf.py. Both configuration systems work at the same
 time, so you can set your options in both, but if you are hesitating
 about which alternative to choose, we recommend the ipy_user_conf.py
 approach, as it will give you more power and control in the long
 run. However, there are few options such as pylab_import_all that can
 only be specified in ipythonrc file or command line - the reason for
 this is that they are needed before IPython has been started up, and
 the IPApi object used in ipy_user_conf.py is not yet available at that
 time. A hybrid approach of specifying a few options in ipythonrc and
 doing the more advanced configuration in ipy_user_conf.py is also
 possible.
 
 The ipythonrc approach
 ----------------------
 
 As we've already mentioned, IPython reads a configuration file which can
 be specified at the command line (-rcfile) or which by default is
 assumed to be called ipythonrc. Such a file is looked for in the current
 directory where IPython is started and then in your IPYTHONDIR, which
 allows you to have local configuration files for specific projects. In
 this section we will call these types of configuration files simply
 rcfiles (short for resource configuration file).
 
 The syntax of an rcfile is one of key-value pairs separated by
 whitespace, one per line. Lines beginning with a # are ignored as
 comments, but comments can not be put on lines with data (the parser is
 fairly primitive). Note that these are not python files, and this is
 deliberate, because it allows us to do some things which would be quite
 tricky to implement if they were normal python files.
 
 First, an rcfile can contain permanent default values for almost all
 command line options (except things like -help or -Version). Sec
 `command line options`_ contains a description of all command-line
 options. However, values you explicitly specify at the command line
 override the values defined in the rcfile.
 
 Besides command line option values, the rcfile can specify values for
 certain extra special options which are not available at the command
 line. These options are briefly described below.
 
 Each of these options may appear as many times as you need it in the file.
 
     * include <file1> <file2> ...: you can name other rcfiles you want
       to recursively load up to 15 levels (don't use the <> brackets in
       your names!). This feature allows you to define a 'base' rcfile
       with general options and special-purpose files which can be loaded
       only when needed with particular configuration options. To make
       this more convenient, IPython accepts the -profile <name> option
       (abbreviates to -p <name>) which tells it to look for an rcfile
       named ipythonrc-<name>.
     * import_mod <mod1> <mod2> ...: import modules with 'import
       <mod1>,<mod2>,...'
     * import_some <mod> <f1> <f2> ...: import functions with 'from
       <mod> import <f1>,<f2>,...'
     * import_all <mod1> <mod2> ...: for each module listed import
       functions with ``from <mod> import *``.
     * execute <python code>: give any single-line python code to be
       executed.
     * execfile <filename>: execute the python file given with an
       'execfile(filename)' command. Username expansion is performed on
       the given names. So if you need any amount of extra fancy
       customization that won't fit in any of the above 'canned' options,
       you can just put it in a separate python file and execute it.
     * alias <alias_def>: this is equivalent to calling
       '%alias <alias_def>' at the IPython command line. This way, from
       within IPython you can do common system tasks without having to
       exit it or use the ! escape. IPython isn't meant to be a shell
       replacement, but it is often very useful to be able to do things
       with files while testing code. This gives you the flexibility to
       have within IPython any aliases you may be used to under your
       normal system shell.

 Sample ipythonrc file
 ---------------------
 
 The default rcfile, called ipythonrc and supplied in your IPYTHONDIR
 directory contains lots of comments on all of these options. We
 reproduce it here for reference::

     #
     # Configuration file for IPython -- ipythonrc format
     #
     # ===========================================================
     # Deprecation note: you should look into modifying ipy_user_conf.py (located 
     # in ~/.ipython or ~/_ipython, depending on your platform) instead, it's a 
     # more flexible and robust (and better supported!) configuration
     # method.
     # ===========================================================
     #
     # The format of this file is simply one of 'key value' lines.
     # Lines containing only whitespace at the beginning and then a # are ignored
     # as comments. But comments can NOT be put on lines with data.
 
     # The meaning and use of each key are explained below.
 
     #---------------------------------------------------------------------------
     # Section: included files
 
     # Put one or more *config* files (with the syntax of this file) you want to
     # include. For keys with a unique value the outermost file has precedence. For
     # keys with multiple values, they all get assembled into a list which then
     # gets loaded by IPython.
 
     # In this file, all lists of things should simply be space-separated.
 
     # This allows you to build hierarchies of files which recursively load
     # lower-level services. If this is your main ~/.ipython/ipythonrc file, you
     # should only keep here basic things you always want available. Then you can
     # include it in every other special-purpose config file you create.
     include 
 
     #---------------------------------------------------------------------------
     # Section: startup setup
 
     # These are mostly things which parallel a command line option of the same
     # name.
 
     # Keys in this section should only appear once. If any key from this section
     # is encountered more than once, the last value remains, all earlier ones get
     # discarded.
 
 
     # Automatic calling of callable objects.  If set to 1 or 2, callable objects
     # are automatically called when invoked at the command line, even if you don't
     # type parentheses.  IPython adds the parentheses for you.  For example:
 
     #In [1]: str 45
     #------> str(45)
     #Out[1]: '45'
 
     # IPython reprints your line with '---->' indicating that it added
     # parentheses.  While this option is very convenient for interactive use, it
     # may occasionally cause problems with objects which have side-effects if
     # called unexpectedly.
 
     # The valid values for autocall are:
 
     # autocall 0 -> disabled (you can toggle it at runtime with the %autocall magic)
 
     # autocall 1 -> active, but do not apply if there are no arguments on the line.
 
     # In this mode, you get:
 
     #In [1]: callable
     #Out[1]: <built-in function callable>
 
     #In [2]: callable 'hello'
     #------> callable('hello')
     #Out[2]: False
 
     # 2 -> Active always.  Even if no arguments are present, the callable object
     # is called:
 
     #In [4]: callable
     #------> callable()
 
     # Note that even with autocall off, you can still use '/' at the start of a
     # line to treat the first argument on the command line as a function and add
     # parentheses to it:
 
     #In [8]: /str 43
     #------> str(43)
     #Out[8]: '43'
 
     autocall 1
 
     # Auto-edit syntax errors.  When you use the %edit magic in ipython to edit
     # source code (see the 'editor' variable below), it is possible that you save
     # a file with syntax errors in it.  If this variable is true, IPython will ask
     # you whether to re-open the editor immediately to correct such an error.
 
     autoedit_syntax 0
 
     # Auto-indent. IPython can recognize lines ending in ':' and indent the next
     # line, while also un-indenting automatically after 'raise' or 'return'.  
 
     # This feature uses the readline library, so it will honor your ~/.inputrc
     # configuration (or whatever file your INPUTRC variable points to).  Adding
     # the following lines to your .inputrc file can make indent/unindenting more
     # convenient (M-i indents, M-u unindents):
 
     #  $if Python
     #  "\M-i": "    "
     #  "\M-u": "\d\d\d\d"
     #  $endif
 
     # The feature is potentially a bit dangerous, because it can cause problems
     # with pasting of indented code (the pasted code gets re-indented on each
     # line).  But it's a huge time-saver when working interactively.  The magic
     # function %autoindent allows you to toggle it on/off at runtime.
 
     autoindent 1
 
     # Auto-magic. This gives you access to all the magic functions without having
     # to prepend them with an % sign. If you define a variable with the same name
     # as a magic function (say who=1), you will need to access the magic function
     # with % (%who in this example). However, if later you delete your variable
     # (del who), you'll recover the automagic calling form.
 
     # Considering that many magic functions provide a lot of shell-like
     # functionality, automagic gives you something close to a full Python+system
     # shell environment (and you can extend it further if you want).

     # Size of the output cache. After this many entries are stored, the cache will
     # get flushed. Depending on the size of your intermediate calculations, you
     # may have memory problems if you make it too big, since keeping things in the
     # cache prevents Python from reclaiming the memory for old results. Experiment
     # with a value that works well for you.
 
     # If you choose cache_size 0 IPython will revert to python's regular >>>
     # unnumbered prompt. You will still have _, __ and ___ for your last three
     # results, but that will be it.  No dynamic _1, _2, etc. will be created. If
     # you are running on a slow machine or with very limited memory, this may
     # help.

     # IPython emulating most of the classic interpreter's behavior.

     # colors - Coloring option for prompts and traceback printouts.
 
     # Currently available schemes: NoColor, Linux, LightBG.
 
     # This option allows coloring the prompts and traceback printouts. This
     # requires a terminal which can properly handle color escape sequences. If you
     # are having problems with this, use the NoColor scheme (uses no color escapes
     # at all).
 
     # The Linux option works well in linux console type environments: dark

     # Section: modules to import some functions from: 'from ... import ...'
 
     # List, one per line, the modules for which you want only to import some
     # functions. Give the module name first and then the name of functions to be
     # imported from that module.
 
     # Example:
 
     # import_some IPython.genutils timing timings
     # will produce internally the statement
     # from IPython.genutils import timing, timings
 
     # timing() and timings() are two IPython utilities for timing the execution of
     # your own functions, which you may find useful.  Just commment out the above
     # line if you want to test them.
 
     # If you have more than one modules_some line, each gets its own try/except
     # block (like modules, see above).
 
     import_some 
 
     #---------------------------------------------------------------------------
     # Section: modules to import all from : 'from ... import *'
 
     # List (same syntax as import_mod above) those modules for which you want to
     # import all functions. Remember, this is a potentially dangerous thing to do,
     # since it is very easy to overwrite names of things you need. Use with
     # caution.
 
     # Example:
     # import_all sys os
     # will produce internally the statements
     # from sys import *
     # from os import *
 
     # As before, each will be called in a separate try/except block.
 
     import_all 
 
     #---------------------------------------------------------------------------
     # Section: Python code to execute.
 
     # Put here code to be explicitly executed (keep it simple!)
     # Put one line of python code per line. All whitespace is removed (this is a
     # feature, not a bug), so don't get fancy building loops here.
     # This is just for quick convenient creation of things you want available.
 
     # Example:
     # execute x = 1
     # execute print 'hello world'; y = z = 'a'
     # will produce internally
     # x = 1
     # print 'hello world'; y = z = 'a'
     # and each *line* (not each statement, we don't do python syntax parsing) is
     # executed in its own try/except block.
 
     execute 
 
     # Note for the adventurous: you can use this to define your own names for the
     # magic functions, by playing some namespace tricks:
 
     # execute __IPYTHON__.magic_pf = __IPYTHON__.magic_profile
 
     # defines %pf as a new name for %profile.
 
     #---------------------------------------------------------------------------
     # Section: Pyhton files to load and execute.
 
     # Put here the full names of files you want executed with execfile(file).  If
     # you want complicated initialization, just write whatever you want in a
     # regular python file and load it from here.
 
     # Filenames defined here (which *must* include the extension) are searched for
     # through all of sys.path. Since IPython adds your .ipython directory to
     # sys.path, they can also be placed in your .ipython dir and will be
     # found. Otherwise (if you want to execute things not in .ipyton nor in
     # sys.path) give a full path (you can use ~, it gets expanded)
 
     # Example:
     # execfile file1.py ~/file2.py
     # will generate
     # execfile('file1.py')
     # execfile('_path_to_your_home/file2.py')
 
     # As before, each file gets its own try/except block.
 
     execfile
 
     # If you are feeling adventurous, you can even add functionality to IPython
     # through here. IPython works through a global variable called __ip which
     # exists at the time when these files are read. If you know what you are doing
     # (read the source) you can add functions to __ip in files loaded here. 
 
     # The file example-magic.py contains a simple but correct example. Try it:
 
     # execfile example-magic.py
 
     # Look at the examples in IPython/iplib.py for more details on how these magic
     # functions need to process their arguments.
 
     #---------------------------------------------------------------------------
     # Section: aliases for system shell commands
 
     # Here you can define your own names for system commands. The syntax is
     # similar to that of the builtin %alias function:
 
     # alias alias_name command_string
 
     # The resulting aliases are auto-generated magic functions (hence usable as
     # %alias_name)
 
     # For example:
 
     # alias myls ls -la
 
     # will define 'myls' as an alias for executing the system command 'ls -la'.
     # This allows you to customize IPython's environment to have the same aliases
     # you are accustomed to from your own shell.
 
     # You can also define aliases with parameters using %s specifiers (one per
     # parameter):
 
     # alias parts echo first %s second %s
 
     # will give you in IPython:
     # >>> %parts A B
     # first A second B
 
     # Use one 'alias' statement per alias you wish to define.
 
     # alias

 ipy_user_conf.py
 ----------------
 
 There should be a simple template ipy_user_conf.py file in your
 ~/.ipython directory. It is a plain python module that is imported
 during IPython startup, so you can do pretty much what you want there
 - import modules, configure extensions, change options, define magic
 commands, put variables and functions in the IPython namespace,
 etc. You use the IPython extension api object, acquired by
 IPython.ipapi.get() and documented in the "IPython extension API"
 chapter, to interact with IPython. A sample ipy_user_conf.py is listed
 below for reference::
 
     # Most of your config files and extensions will probably start
     # with this import
 
     import IPython.ipapi
     ip = IPython.ipapi.get()
 
     # You probably want to uncomment this if you did %upgrade -nolegacy
     # import ipy_defaults    
 
     import os   
 
     def main():   
 
         #ip.dbg.debugmode = True
         ip.dbg.debug_stack()
 
         # uncomment if you want to get ipython -p sh behaviour
         # without having to use command line switches  
         import ipy_profile_sh
         import jobctrl
 
         # Configure your favourite editor?
         # Good idea e.g. for %edit os.path.isfile
 
         #import ipy_editors
 
         # Choose one of these:
 
         #ipy_editors.scite()
         #ipy_editors.scite('c:/opt/scite/scite.exe')
         #ipy_editors.komodo()
         #ipy_editors.idle()
         # ... or many others, try 'ipy_editors??' after import to see them
 
         # Or roll your own:
         #ipy_editors.install_editor("c:/opt/jed +$line $file")
 
 
         o = ip.options
         # An example on how to set options
         #o.autocall = 1
         o.system_verbose = 0
 
         #import_all("os sys")
         #execf('~/_ipython/ns.py')
 
 
         # -- prompt
         # A different, more compact set of prompts from the default ones, that
         # always show your current location in the filesystem:

         #o.autoexec.append('%colors NoColor')
         o.autoexec.append('%colors Linux')

     def import_all(modules):
         """ Usage: import_all("os sys") """ 
         for m in modules.split():
             ip.ex("from %s import *" % m)

         ip.ex('execfile("%s")' % os.path.expanduser(fname))
 
     main()
 
 .. _Prompts:
 
 Fine-tuning your prompt
 -----------------------
 
 IPython's prompts can be customized using a syntax similar to that of
 the bash shell. Many of bash's escapes are supported, as well as a few
 additional ones. We list them below::
 
     \#
         the prompt/history count number. This escape is automatically
         wrapped in the coloring codes for the currently active color scheme. 
     \N
         the 'naked' prompt/history count number: this is just the number
         itself, without any coloring applied to it. This lets you produce
         numbered prompts with your own colors. 
     \D
         the prompt/history count, with the actual digits replaced by dots.
         Used mainly in continuation prompts (prompt_in2) 
     \w
         the current working directory 
     \W
         the basename of current working directory 
     \Xn
         where $n=0\ldots5.$ The current working directory, with $HOME
         replaced by ~, and filtered out to contain only $n$ path elements 
     \Yn
         Similar to \Xn, but with the $n+1$ element included if it is ~ (this
         is similar to the behavior of the %cn escapes in tcsh) 
     \u
         the username of the current user 
     \$
         if the effective UID is 0, a #, otherwise a $ 
     \h
         the hostname up to the first '.' 
     \H
         the hostname 
     \n
         a newline 
     \r
         a carriage return 
     \v
         IPython version string 
 
 In addition to these, ANSI color escapes can be insterted into the
 prompts, as \C_ColorName. The list of valid color names is: Black, Blue,
 Brown, Cyan, DarkGray, Green, LightBlue, LightCyan, LightGray,
 LightGreen, LightPurple, LightRed, NoColor, Normal, Purple, Red, White,
 Yellow.
 
 Finally, IPython supports the evaluation of arbitrary expressions in
 your prompt string. The prompt strings are evaluated through the syntax
 of PEP 215, but basically you can use $x.y to expand the value of x.y,
 and for more complicated expressions you can use braces: ${foo()+x} will
 call function foo and add to it the value of x, before putting the
 result into your prompt. For example, using
 prompt_in1 '${commands.getoutput("uptime")}\nIn [\#]: ' 
 will print the result of the uptime command on each prompt (assuming the
 commands module has been imported in your ipythonrc file).
 
 
       Prompt examples
 
 The following options in an ipythonrc file will give you IPython's
 default prompts::
 
     prompt_in1 'In [\#]:' 
     prompt_in2 '   .\D.:' 
     prompt_out 'Out[\#]:'
 
 which look like this::
 
     In [1]: 1+2 
     Out[1]: 3
 
     In [2]: for i in (1,2,3): 
        ...:    print i, 
        ...: 
     1 2 3
 
 These will give you a very colorful prompt with path information::
 
     #prompt_in1 '\C_Red\u\C_Blue[\C_Cyan\Y1\C_Blue]\C_LightGreen\#>' 
     prompt_in2 ' ..\D>' 
     prompt_out '<\#>'
 
 which look like this::
 
     fperez[~/ipython]1> 1+2 
                     <1> 3 
     fperez[~/ipython]2> for i in (1,2,3): 
                    ...>     print i, 
                    ...> 
     1 2 3
 
 
 .. _Profiles:
 
 IPython profiles
 ----------------
 
 As we already mentioned, IPython supports the -profile command-line
 option (see sec. `command line options`_). A profile is nothing more
 than a particular configuration file like your basic ipythonrc one,
 but with particular customizations for a specific purpose. When you
 start IPython with 'ipython -profile <name>', it assumes that in your
 IPYTHONDIR there is a file called ipythonrc-<name> or
 ipy_profile_<name>.py, and loads it instead of the normal ipythonrc.
 
 This system allows you to maintain multiple configurations which load
 modules, set options, define functions, etc. suitable for different
 tasks and activate them in a very simple manner. In order to avoid
 having to repeat all of your basic options (common things that don't
 change such as your color preferences, for example), any profile can
 include another configuration file. The most common way to use profiles
 is then to have each one include your basic ipythonrc file as a starting
 point, and then add further customizations.
 
 IPython as your default Python environment
 ==========================================
 
 Python honors the environment variable PYTHONSTARTUP and will execute at
 startup the file referenced by this variable. If you put at the end of
 this file the following two lines of code::
 
     import IPython 
     IPython.Shell.IPShell().mainloop(sys_exit=1)
 
 then IPython will be your working environment anytime you start Python.
 The sys_exit=1 is needed to have IPython issue a call to sys.exit() when
 it finishes, otherwise you'll be back at the normal Python '>>>'
 prompt.
 
 This is probably useful to developers who manage multiple Python
 versions and don't want to have correspondingly multiple IPython
 versions. Note that in this mode, there is no way to pass IPython any
 command-line options, as those are trapped first by Python itself.
 
 .. _Embedding:
 
 Embedding IPython
 =================
 
 It is possible to start an IPython instance inside your own Python
 programs. This allows you to evaluate dynamically the state of your
 code, operate with your variables, analyze them, etc. Note however that
 any changes you make to values while in the shell do not propagate back
 to the running code, so it is safe to modify your values because you
 won't break your code in bizarre ways by doing so.
 
 This feature allows you to easily have a fully functional python
 environment for doing object introspection anywhere in your code with a
 simple function call. In some cases a simple print statement is enough,
 but if you need to do more detailed analysis of a code fragment this
 feature can be very valuable.
 
 It can also be useful in scientific computing situations where it is
 common to need to do some automatic, computationally intensive part and
 then stop to look at data, plots, etc.
 Opening an IPython instance will give you full access to your data and
 functions, and you can resume program execution once you are done with
 the interactive part (perhaps to stop again later, as many times as
 needed).
 
 The following code snippet is the bare minimum you need to include in
 your Python programs for this to work (detailed examples follow later)::
 
     from IPython.Shell import IPShellEmbed
 
     ipshell = IPShellEmbed()
 
     ipshell() # this call anywhere in your program will start IPython
 
 You can run embedded instances even in code which is itself being run at
 the IPython interactive prompt with '%run <filename>'. Since it's easy
 to get lost as to where you are (in your top-level IPython or in your
 embedded one), it's a good idea in such cases to set the in/out prompts
 to something different for the embedded instances. The code examples
 below illustrate this.
 
 You can also have multiple IPython instances in your program and open
 them separately, for example with different options for data
 presentation. If you close and open the same instance multiple times,
 its prompt counters simply continue from each execution to the next.
 
 Please look at the docstrings in the Shell.py module for more details on
 the use of this system.
 
 The following sample file illustrating how to use the embedding
 functionality is provided in the examples directory as example-embed.py.
 It should be fairly self-explanatory::
 
 
     #!/usr/bin/env python
 
     """An example of how to embed an IPython shell into a running program.
 
     Please see the documentation in the IPython.Shell module for more details.
 
     The accompanying file example-embed-short.py has quick code fragments for
     embedding which you can cut and paste in your code once you understand how
     things work.
 
     The code in this file is deliberately extra-verbose, meant for learning."""
 
     # The basics to get you going:

     # %run example-embed.py)

     # - A global startup banner.
 
     # - A call-specific header string, which you can use to indicate where in the

 Using the Python debugger (pdb)
 ===============================
 
 Running entire programs via pdb
 -------------------------------
 
 pdb, the Python debugger, is a powerful interactive debugger which
 allows you to step through code, set breakpoints, watch variables,
 etc.  IPython makes it very easy to start any script under the control
 of pdb, regardless of whether you have wrapped it into a 'main()'
 function or not. For this, simply type '%run -d myscript' at an
 IPython prompt. See the %run command's documentation (via '%run?' or
 in Sec. magic_ for more details, including how to control where pdb
 will stop execution first.
 
 For more information on the use of the pdb debugger, read the included
 pdb.doc file (part of the standard Python distribution). On a stock
 Linux system it is located at /usr/lib/python2.3/pdb.doc, but the
 easiest way to read it is by using the help() function of the pdb module
 as follows (in an IPython prompt):
 
 In [1]: import pdb 
 In [2]: pdb.help()
 
 This will load the pdb.doc document in a file viewer for you automatically.
 
 
 Automatic invocation of pdb on exceptions
 -----------------------------------------
 
 IPython, if started with the -pdb option (or if the option is set in
 your rc file) can call the Python pdb debugger every time your code
 triggers an uncaught exception. This feature
 can also be toggled at any time with the %pdb magic command. This can be
 extremely useful in order to find the origin of subtle bugs, because pdb
 opens up at the point in your code which triggered the exception, and
 while your program is at this point 'dead', all the data is still
 available and you can walk up and down the stack frame and understand
 the origin of the problem.
 
 Furthermore, you can use these debugging facilities both with the
 embedded IPython mode and without IPython at all. For an embedded shell
 (see sec. Embedding_), simply call the constructor with
 '-pdb' in the argument string and automatically pdb will be called if an
 uncaught exception is triggered by your code.
 
 For stand-alone use of the feature in your programs which do not use
 IPython at all, put the following lines toward the top of your 'main'
 routine::
 
     import sys,IPython.ultraTB  
     sys.excepthook = IPython.ultraTB.FormattedTB(mode='Verbose',
     color_scheme='Linux', call_pdb=1)
 
 The mode keyword can be either 'Verbose' or 'Plain', giving either very
 detailed or normal tracebacks respectively. The color_scheme keyword can
 be one of 'NoColor', 'Linux' (default) or 'LightBG'. These are the same
 options which can be set in IPython with -colors and -xmode.
 
 This will give any of your programs detailed, colored tracebacks with
 automatic invocation of pdb.
 
 
 Extensions for syntax processing
 ================================
 
 This isn't for the faint of heart, because the potential for breaking
 things is quite high. But it can be a very powerful and useful feature.
 In a nutshell, you can redefine the way IPython processes the user input
 line to accept new, special extensions to the syntax without needing to
 change any of IPython's own code.
 
 In the IPython/Extensions directory you will find some examples
 supplied, which we will briefly describe now. These can be used 'as is'
 (and both provide very useful functionality), or you can use them as a
 starting point for writing your own extensions.
 
 
 Pasting of code starting with '>>> ' or '... '
 ----------------------------------------------
 
 In the python tutorial it is common to find code examples which have
 been taken from real python sessions. The problem with those is that all
 the lines begin with either '>>> ' or '... ', which makes it impossible
 to paste them all at once. One must instead do a line by line manual
 copying, carefully removing the leading extraneous characters.
 
 This extension identifies those starting characters and removes them
 from the input automatically, so that one can paste multi-line examples
 directly into IPython, saving a lot of time. Please look at the file
 InterpreterPasteInput.py in the IPython/Extensions directory for details
 on how this is done.
 
 IPython comes with a special profile enabling this feature, called
 tutorial. Simply start IPython via 'ipython -p tutorial' and the feature
 will be available. In a normal IPython session you can activate the
 feature by importing the corresponding module with:
 In [1]: import IPython.Extensions.InterpreterPasteInput
 
 The following is a 'screenshot' of how things work when this extension
 is on, copying an example from the standard tutorial::
 
     IPython profile: tutorial 
 
     *** Pasting of code with ">>>" or "..." has been enabled. 
 
     In [1]: >>> def fib2(n): # return Fibonacci series up to n 
        ...: ...     """Return a list containing the Fibonacci series up to
     n.""" 
        ...: ...     result = [] 
        ...: ...     a, b = 0, 1 
        ...: ...     while b < n: 
        ...: ...         result.append(b)    # see below 
        ...: ...         a, b = b, a+b 
        ...: ...     return result 
        ...: 
 
     In [2]: fib2(10) 
     Out[2]: [1, 1, 2, 3, 5, 8]
 
 Note that as currently written, this extension does not recognize
 IPython's prompts for pasting. Those are more complicated, since the
 user can change them very easily, they involve numbers and can vary in
 length. One could however extract all the relevant information from the
 IPython instance and build an appropriate regular expression. This is
 left as an exercise for the reader.
 
 
 Input of physical quantities with units
 ---------------------------------------
 
 The module PhysicalQInput allows a simplified form of input for physical
 quantities with units. This file is meant to be used in conjunction with
 the PhysicalQInteractive module (in the same directory) and
 Physics.PhysicalQuantities from Konrad Hinsen's ScientificPython
 (http://dirac.cnrs-orleans.fr/ScientificPython/).
 
 The Physics.PhysicalQuantities module defines PhysicalQuantity objects,
 but these must be declared as instances of a class. For example, to
 define v as a velocity of 3 m/s, normally you would write::
 
     In [1]: v = PhysicalQuantity(3,'m/s')
 
 Using the PhysicalQ_Input extension this can be input instead as: 
 In [1]: v = 3 m/s
 which is much more convenient for interactive use (even though it is
 blatantly invalid Python syntax).
 
 The physics profile supplied with IPython (enabled via 'ipython -p
 physics') uses these extensions, which you can also activate with:
 
 from math import * # math MUST be imported BEFORE PhysicalQInteractive 
 from IPython.Extensions.PhysicalQInteractive import * 
 import IPython.Extensions.PhysicalQInput
 
 
 IPython as a system shell - the 'Sh' profile
 ============================================
 
 The 'sh' profile optimizes IPython for system shell usage. Apart from
 certain job control functionality that is present in unix (ctrl+z does
 "suspend"), the sh profile should provide you with most of the
 functionality you use daily in system shell, and more. Invoke IPython
 in 'sh' profile by doing 'ipython -p sh', or (in win32) by launching
 the "pysh" shortcut in start menu.
 
 If you want to use the features of sh profile as your defaults (which
 might be a good idea if you use other profiles a lot of the time but
 still want the convenience of sh profile), add ``import ipy_profile_sh``
 to your ~/.ipython/ipy_user_conf.py.
 
 The 'sh' profile is different from the default profile in that:
 
  * Prompt shows the current directory
  * Spacing between prompts and input is more compact (no padding with
    empty lines). The startup banner is more compact as well.
  * System commands are directly available (in alias table) without
    requesting %rehashx - however, if you install new programs along
    your PATH, you might want to run %rehashx to update the persistent
    alias table
  * Macros are stored in raw format by default. That is, instead of
    '_ip.system("cat foo"), the macro will contain text 'cat foo')
  * Autocall is in full mode
  * Calling "up" does "cd .."
 
 The 'sh' profile is different from the now-obsolete (and unavailable)
 'pysh' profile in that:
 
  * '$$var = command' and '$var = command' syntax is not supported
  * anymore. Use 'var = !command' instead (incidentally, this is
  * available in all IPython profiles). Note that !!command *will*
  * work.
 
 Aliases
 -------
 
 All of your $PATH has been loaded as IPython aliases, so you should be
 able to type any normal system command and have it executed. See
 %alias?  and %unalias? for details on the alias facilities. See also
 %rehashx? for details on the mechanism used to load $PATH.
 
 
 Directory management
 --------------------
 
 Since each command passed by ipython to the underlying system is executed
 in a subshell which exits immediately, you can NOT use !cd to navigate
 the filesystem.
 
 IPython provides its own builtin '%cd' magic command to move in the
 filesystem (the % is not required with automagic on). It also maintains
 a list of visited directories (use %dhist to see it) and allows direct
 switching to any of them. Type 'cd?' for more details.
 
 %pushd, %popd and %dirs are provided for directory stack handling.
 
 
 Enabled extensions
 ------------------
 
 Some extensions, listed below, are enabled as default in this profile.
 
 envpersist
 ++++++++++
 
 %env can be used to "remember" environment variable manipulations. Examples::
 
 	%env - Show all environment variables
 	%env VISUAL=jed  - set VISUAL to jed
 	%env PATH+=;/foo - append ;foo to PATH
 	%env PATH+=;/bar - also append ;bar to PATH
 	%env PATH-=/wbin; - prepend /wbin; to PATH
 	%env -d VISUAL   - forget VISUAL persistent val
 	%env -p          - print all persistent env modifications
 
 ipy_which
 +++++++++
 
 %which magic command. Like 'which' in unix, but knows about ipython aliases.
 
 Example::
 
  [C:/ipython]|14> %which st
  st -> start .
  [C:/ipython]|15> %which d
  d -> dir /w /og /on
  [C:/ipython]|16> %which cp
  cp -> cp
    == c:\bin\cp.exe
  c:\bin\cp.exe
 
 ipy_app_completers
 ++++++++++++++++++
 
 Custom tab completers for some apps like svn, hg, bzr, apt-get. Try 'apt-get install <TAB>' in debian/ubuntu.
 
 ipy_rehashdir
 +++++++++++++
 
 Allows you to add system command aliases for commands that are not along your path. Let's say that you just installed Putty and want to be able to invoke it without adding it to path, you can create the alias for it with rehashdir::
 
  [~]|22> cd c:/opt/PuTTY/
  [c:opt/PuTTY]|23> rehashdir .
               <23> ['pageant', 'plink', 'pscp', 'psftp', 'putty', 'puttygen', 'unins000']
 
 Now, you can execute any of those commams directly::
 
  [c:opt/PuTTY]|24> cd
  [~]|25> putty
 
 (the putty window opens).
 
 If you want to store the alias so that it will always be available, do '%store putty'. If you want to %store all these aliases persistently, just do it in a for loop::
 
  [~]|27> for a in _23:
     |..>     %store $a
     |..>
     |..>
  Alias stored: pageant (0, 'c:\\opt\\PuTTY\\pageant.exe')
  Alias stored: plink (0, 'c:\\opt\\PuTTY\\plink.exe')
  Alias stored: pscp (0, 'c:\\opt\\PuTTY\\pscp.exe')
  Alias stored: psftp (0, 'c:\\opt\\PuTTY\\psftp.exe')
  ...
 
 mglob
 +++++
 
 Provide the magic function %mglob, which makes it easier (than the 'find' command) to collect (possibly recursive) file lists. Examples::
 
  [c:/ipython]|9> mglob *.py
  [c:/ipython]|10> mglob *.py rec:*.txt
  [c:/ipython]|19> workfiles = %mglob !.svn/ !.hg/ !*_Data/ !*.bak rec:.
 
 Note that the first 2 calls will put the file list in result history (_, _9, _10), and the last one will assign it to 'workfiles'.
 
 
 Prompt customization
 --------------------
 
 The sh profile uses the following prompt configurations::
 
     o.prompt_in1= r'\C_LightBlue[\C_LightCyan\Y2\C_LightBlue]\C_Green|\#>'
     o.prompt_in2= r'\C_Green|\C_LightGreen\D\C_Green>'
 
 You can change the prompt configuration to your liking by editing
 ipy_user_conf.py.  
 
 String lists
 ============
 
 String lists (IPython.genutils.SList) are handy way to process output
 from system commands. They are produced by ``var = !cmd`` syntax.
 
 First, we acquire the output of 'ls -l'::
 
     [Q:doc/examples]|2> lines = !ls -l
      ==
     ['total 23',
      '-rw-rw-rw- 1 ville None 1163 Sep 30  2006 example-demo.py',
      '-rw-rw-rw- 1 ville None 1927 Sep 30  2006 example-embed-short.py',
      '-rwxrwxrwx 1 ville None 4606 Sep  1 17:15 example-embed.py',
      '-rwxrwxrwx 1 ville None 1017 Sep 30  2006 example-gnuplot.py',
      '-rwxrwxrwx 1 ville None  339 Jun 11 18:01 extension.py',
      '-rwxrwxrwx 1 ville None  113 Dec 20  2006 seteditor.py',
      '-rwxrwxrwx 1 ville None  245 Dec 12  2006 seteditor.pyc']
 
 Now, let's take a look at the contents of 'lines' (the first number is
 the list element number)::
 
     [Q:doc/examples]|3> lines
                     <3> SList (.p, .n, .l, .s, .grep(), .fields() available). Value:
 
     0: total 23
     1: -rw-rw-rw- 1 ville None 1163 Sep 30  2006 example-demo.py
     2: -rw-rw-rw- 1 ville None 1927 Sep 30  2006 example-embed-short.py
     3: -rwxrwxrwx 1 ville None 4606 Sep  1 17:15 example-embed.py
     4: -rwxrwxrwx 1 ville None 1017 Sep 30  2006 example-gnuplot.py
     5: -rwxrwxrwx 1 ville None  339 Jun 11 18:01 extension.py
     6: -rwxrwxrwx 1 ville None  113 Dec 20  2006 seteditor.py
     7: -rwxrwxrwx 1 ville None  245 Dec 12  2006 seteditor.pyc
 
 Now, let's filter out the 'embed' lines::
 
     [Q:doc/examples]|4> l2 = lines.grep('embed',prune=1)
     [Q:doc/examples]|5> l2
                     <5> SList (.p, .n, .l, .s, .grep(), .fields() available). Value:
 
     0: total 23
     1: -rw-rw-rw- 1 ville None 1163 Sep 30  2006 example-demo.py
     2: -rwxrwxrwx 1 ville None 1017 Sep 30  2006 example-gnuplot.py
     3: -rwxrwxrwx 1 ville None  339 Jun 11 18:01 extension.py
     4: -rwxrwxrwx 1 ville None  113 Dec 20  2006 seteditor.py
     5: -rwxrwxrwx 1 ville None  245 Dec 12  2006 seteditor.pyc
 
 Now, we want strings having just file names and permissions::
 
     [Q:doc/examples]|6> l2.fields(8,0)
                     <6> SList (.p, .n, .l, .s, .grep(), .fields() available). Value:
 
     0: total
     1: example-demo.py -rw-rw-rw-
     2: example-gnuplot.py -rwxrwxrwx
     3: extension.py -rwxrwxrwx
     4: seteditor.py -rwxrwxrwx
     5: seteditor.pyc -rwxrwxrwx
 
 Note how the line with 'total' does not raise IndexError.
 
 If you want to split these (yielding lists), call fields() without
 arguments::
 
     [Q:doc/examples]|7> _.fields()
                     <7>
     [['total'],
      ['example-demo.py', '-rw-rw-rw-'],
      ['example-gnuplot.py', '-rwxrwxrwx'],
      ['extension.py', '-rwxrwxrwx'],
      ['seteditor.py', '-rwxrwxrwx'],
      ['seteditor.pyc', '-rwxrwxrwx']]
 
 If you want to pass these separated with spaces to a command (typical
 for lists if files), use the .s property::
 
 
     [Q:doc/examples]|13> files = l2.fields(8).s
     [Q:doc/examples]|14> files
                     <14> 'example-demo.py example-gnuplot.py extension.py seteditor.py seteditor.pyc'
     [Q:doc/examples]|15> ls $files
     example-demo.py  example-gnuplot.py  extension.py  seteditor.py  seteditor.pyc
 
 SLists are inherited from normal python lists, so every list method is
 available::
 
     [Q:doc/examples]|21> lines.append('hey')
 
 
 Real world example: remove all files outside version control
 ------------------------------------------------------------
 
 First, capture output of "hg status"::
 
     [Q:/ipython]|28> out = !hg status
      ==
     ['M IPython\\Extensions\\ipy_kitcfg.py',
      'M IPython\\Extensions\\ipy_rehashdir.py',
     ...
      '? build\\lib\\IPython\\Debugger.py',
      '? build\\lib\\IPython\\Extensions\\InterpreterExec.py',
      '? build\\lib\\IPython\\Extensions\\InterpreterPasteInput.py',
     ...
 
 (lines starting with ? are not under version control).
 
 ::
 
     [Q:/ipython]|35> junk = out.grep(r'^\?').fields(1)
     [Q:/ipython]|36> junk
                 <36> SList (.p, .n, .l, .s, .grep(), .fields() availab
     ...
     10: build\bdist.win32\winexe\temp\_ctypes.py
     11: build\bdist.win32\winexe\temp\_hashlib.py
     12: build\bdist.win32\winexe\temp\_socket.py
 
 Now we can just remove these files by doing 'rm $junk.s'. 
 
 The .s, .n, .p properties
 -------------------------
 
 The '.s' property returns one string where lines are separated by
 single space (for convenient passing to system commands). The '.n'
 property return one string where the lines are separated by '\n'
 (i.e. the original output of the function). If the items in string
 list are file names, '.p' can be used to get a list of "path" objects
 for convenient file manipulation.
 
 
 Threading support
 =================
 
 WARNING: The threading support is still somewhat experimental, and it
 has only seen reasonable testing under Linux. Threaded code is
 particularly tricky to debug, and it tends to show extremely
 platform-dependent behavior. Since I only have access to Linux machines,
 I will have to rely on user's experiences and assistance for this area
 of IPython to improve under other platforms.
 
 IPython, via the -gthread , -qthread, -q4thread and -wthread options
 (described in Sec. `Threading options`_), can run in
 multithreaded mode to support pyGTK, Qt3, Qt4 and WXPython applications
 respectively. These GUI toolkits need to control the python main loop of
 execution, so under a normal Python interpreter, starting a pyGTK, Qt3,
 Qt4 or WXPython application will immediately freeze the shell.
 
 IPython, with one of these options (you can only use one at a time),
 separates the graphical loop and IPython's code execution run into
 different threads. This allows you to test interactively (with %run, for
 example) your GUI code without blocking.
 
 A nice mini-tutorial on using IPython along with the Qt Designer
 application is available at the SciPy wiki:
 http://www.scipy.org/Cookbook/Matplotlib/Qt_with_IPython_and_Designer.
 
 
 Tk issues
 ---------
 
 As indicated in Sec. `Threading options`_, a special -tk option is
 provided to try and allow Tk graphical applications to coexist
 interactively with WX, Qt or GTK ones. Whether this works at all,
 however, is very platform and configuration dependent. Please
 experiment with simple test cases before committing to using this
 combination of Tk and GTK/Qt/WX threading in a production environment.
 
 
 I/O pitfalls
 ------------
 
 Be mindful that the Python interpreter switches between threads every
 $N$ bytecodes, where the default value as of Python 2.3 is $N=100.$ This
 value can be read by using the sys.getcheckinterval() function, and it
 can be reset via sys.setcheckinterval(N). This switching of threads can
 cause subtly confusing effects if one of your threads is doing file I/O.
 In text mode, most systems only flush file buffers when they encounter a
 '\n'. An instruction as simple as:: 
 
   print >> filehandle, ''hello world''
 
 actually consists of several bytecodes, so it is possible that the
 newline does not reach your file before the next thread switch.
 Similarly, if you are writing to a file in binary mode, the file won't
 be flushed until the buffer fills, and your other thread may see
 apparently truncated files.
 
 For this reason, if you are using IPython's thread support and have (for
 example) a GUI application which will read data generated by files
 written to from the IPython thread, the safest approach is to open all
 of your files in unbuffered mode (the third argument to the file/open
 function is the buffering value)::
 
   filehandle = open(filename,mode,0)
 
 This is obviously a brute force way of avoiding race conditions with the
 file buffering. If you want to do it cleanly, and you have a resource
 which is being shared by the interactive IPython loop and your GUI
 thread, you should really handle it with thread locking and
 syncrhonization properties. The Python documentation discusses these.
 
 .. _Interactive demos:
 
 Interactive demos with IPython
 ==============================
 
 IPython ships with a basic system for running scripts interactively in
 sections, useful when presenting code to audiences. A few tags embedded
 in comments (so that the script remains valid Python code) divide a file
 into separate blocks, and the demo can be run one block at a time, with
 IPython printing (with syntax highlighting) the block before executing
 it, and returning to the interactive prompt after each block. The
 interactive namespace is updated after each block is run with the
 contents of the demo's namespace.
 
 This allows you to show a piece of code, run it and then execute
 interactively commands based on the variables just created. Once you
 want to continue, you simply execute the next block of the demo. The
 following listing shows the markup necessary for dividing a script into
 sections for execution as a demo::
 
 
     """A simple interactive demo to illustrate the use of IPython's Demo class.
 
     Any python script can be run as a demo, but that does little more than showing
     it on-screen, syntax-highlighted in one shot.  If you add a little simple
     markup, you can stop at specified intervals and return to the ipython prompt,
     resuming execution later.
     """
 
     print 'Hello, welcome to an interactive IPython demo.'
     print 'Executing this block should require confirmation before proceeding,'
     print 'unless auto_all has been set to true in the demo object'
 
     # The mark below defines a block boundary, which is a point where IPython will
     # stop execution and return to the interactive prompt.
     # Note that in actual interactive execution, 
     # <demo> --- stop ---
 
     x = 1
     y = 2
 
     # <demo> --- stop ---
 
     # the mark below makes this block as silent
     # <demo> silent
 
     print 'This is a silent block, which gets executed but not printed.'
 
     # <demo> --- stop ---
     # <demo> auto
     print 'This is an automatic block.'
     print 'It is executed without asking for confirmation, but printed.'
     z = x+y
 
     print 'z=',x
 
     # <demo> --- stop ---
     # This is just another normal block.
     print 'z is now:', z
 
     print 'bye!'
 
 In order to run a file as a demo, you must first make a Demo object out
 of it. If the file is named myscript.py, the following code will make a
 demo::
 
     from IPython.demo import Demo
 
     mydemo = Demo('myscript.py')
 
 This creates the mydemo object, whose blocks you run one at a time by
 simply calling the object with no arguments. If you have autocall active
 in IPython (the default), all you need to do is type::
 
     mydemo 
 
 and IPython will call it, executing each block. Demo objects can be
 restarted, you can move forward or back skipping blocks, re-execute the
 last block, etc. Simply use the Tab key on a demo object to see its
 methods, and call '?' on them to see their docstrings for more usage
 details. In addition, the demo module itself contains a comprehensive
 docstring, which you can access via::
 
     from IPython import demo
 
     demo?
 
 Limitations: It is important to note that these demos are limited to
 fairly simple uses. In particular, you can not put division marks in
 indented code (loops, if statements, function definitions, etc.)
 Supporting something like this would basically require tracking the
 internal execution state of the Python interpreter, so only top-level
 divisions are allowed. If you want to be able to open an IPython
 instance at an arbitrary point in a program, you can use IPython's
 embedding facilities, described in detail in Sec. 9
 
 
 .. _Matplotlib support:
 
 Plotting with matplotlib
 ========================
 
 The matplotlib library (http://matplotlib.sourceforge.net
 http://matplotlib.sourceforge.net) provides high quality 2D plotting for
 Python. Matplotlib can produce plots on screen using a variety of GUI
 toolkits, including Tk, GTK and WXPython. It also provides a number of
 commands useful for scientific computing, all with a syntax compatible
 with that of the popular Matlab program.
 
 IPython accepts the special option -pylab (Sec. `Command line
 options`_). This configures it to support matplotlib, honoring the
 settings in the .matplotlibrc file. IPython will detect the user's
 choice of matplotlib GUI backend, and automatically select the proper
 threading model to prevent blocking. It also sets matplotlib in
 interactive mode and modifies %run slightly, so that any
 matplotlib-based script can be executed using %run and the final
 show() command does not block the interactive shell.
 
 The -pylab option must be given first in order for IPython to
 configure its threading mode. However, you can still issue other
 options afterwards. This allows you to have a matplotlib-based
 environment customized with additional modules using the standard
 IPython profile mechanism (Sec. Profiles_): ''ipython -pylab -p
 myprofile'' will load the profile defined in ipythonrc-myprofile after
 configuring matplotlib.
 
 IPython Extension Api
 =====================
 
 IPython api (defined in IPython/ipapi.py) is the public api that
 should be used for
 
  * Configuration of user preferences (.ipython/ipy_user_conf.py)
  * Creating new profiles (.ipython/ipy_profile_PROFILENAME.py)
  * Writing extensions 
 
 Note that by using the extension api for configuration (editing
 ipy_user_conf.py instead of ipythonrc), you get better validity checks
 and get richer functionality - for example, you can import an
 extension and call functions in it to configure it for your purposes.
 
 For an example extension (the 'sh' profile), see
 IPython/Extensions/ipy_profile_sh.py.
 
 For the last word on what's available, see the source code of
 IPython/ipapi.py.
 
 
 Getting started
 ---------------
 
 If you want to define an extension, create a normal python module that
 can be imported. The module will access IPython functionality through
 the 'ip' object defined below.
 
 If you are creating a new profile (e.g. foobar), name the module as
 'ipy_profile_foobar.py' and put it in your ~/.ipython directory. Then,
 when you start ipython with the '-p foobar' argument, the module is
 automatically imported on ipython startup.
 
 If you are just doing some per-user configuration, you can either 
 
  * Put the commands directly into ipy_user_conf.py. 
 
  * Create a new module with your customization code and import *that*
    module in ipy_user_conf.py. This is preferable to the first approach,
    because now you can reuse and distribute your customization code.
 
 Getting a handle to the api
 ---------------------------
 
 Put this in the start of your module::
 
     #!python
     import IPython.ipapi
     ip = IPython.ipapi.get()
 
 The 'ip' object will then be used for accessing IPython
 functionality. 'ip' will mean this api object in all the following
 code snippets. The same 'ip' that we just acquired is always
 accessible in interactive IPython sessions by the name _ip - play with
 it like this::
 
     [~\_ipython]|81> a = 10
     [~\_ipython]|82> _ip.e
     _ip.ev           _ip.ex           _ip.expose_magic
     [~\_ipython]|82> _ip.ev('a+13')
                 <82> 23
 
 The _ip object is also used in some examples in this document - it can
 be substituted by 'ip' in non-interactive use.
 
 Changing options
 ----------------
 
 The ip object has 'options' attribute that can be used te get/set
 configuration options (just as in the ipythonrc file)::
 
     o = ip.options
     o.autocall = 2
     o.automagic = 1
 
 Executing statements in IPython namespace with 'ex' and 'ev'
 ------------------------------------------------------------
 
 Often, you want to e.g. import some module or define something that
 should be visible in IPython namespace. Use ``ip.ev`` to
 *evaluate* (calculate the value of) expression and ``ip.ex`` to
 '''execute''' a statement::
 
     # path module will be visible to the interactive session
     ip.ex("from path import path" )
 
     # define a handy function 'up' that changes the working directory
 
     ip.ex('import os')
     ip.ex("def up(): os.chdir('..')")
 
 
     # _i2 has the input history entry #2, print its value in uppercase.
     print ip.ev('_i2.upper()')
 
 Accessing the IPython namespace
 -------------------------------
 
 ip.user_ns attribute has a dictionary containing the IPython global
 namespace (the namespace visible in the interactive session).
 
 ::
 
     [~\_ipython]|84> tauno = 555
     [~\_ipython]|85> _ip.user_ns['tauno']
                 <85> 555
 
 Defining new magic commands
 ---------------------------
 
 The following example defines a new magic command, %impall. What the
 command does should be obvious::
 
     def doimp(self, arg):
         ip = self.api
         ip.ex("import %s; reload(%s); from %s import *" % (
         arg,arg,arg)
         )
 
     ip.expose_magic('impall', doimp)
 
 Things to observe in this example:
 
  * Define a function that implements the magic command using the 
    ipapi methods defined in this document
  * The first argument of the function is 'self', i.e. the 
    interpreter object. It shouldn't be used directly. however. 
    The interpreter object is probably *not* going to remain stable 
    through IPython versions.
  * Access the ipapi through 'self.api' instead of the global 'ip' object.
  * All the text following the magic command on the command line is 
    contained in the second argument
  * Expose the magic by ip.expose_magic()
 
 
 Calling magic functions and system commands
 -------------------------------------------
 
 Use ip.magic() to execute a magic function, and ip.system() to execute
 a system command::
 
     # go to a bookmark
     ip.magic('%cd -b relfiles')
 
     # execute 'ls -F' system command. Interchangeable with os.system('ls'), really.
     ip.system('ls -F')
 
 Launching IPython instance from normal python code
 --------------------------------------------------
 
 Use ipapi.launch_new_instance() with an argument that specifies the
 namespace to use. This can be useful for trivially embedding IPython
 into your program. Here's an example of normal python program test.py
 ('''without''' an existing IPython session) that launches an IPython
 interpreter and regains control when the interpreter is exited::
 
     [ipython]|1> cat test.py
     my_ns = dict(
         kissa = 15,
         koira = 16)
     import IPython.ipapi
     print "launching IPython instance"
     IPython.ipapi.launch_new_instance(my_ns)
     print "Exited IPython instance!"
     print "New vals:",my_ns['kissa'], my_ns['koira']
 
 And here's what it looks like when run (note how we don't start it
 from an ipython session)::
 
     Q:\ipython>python test.py
     launching IPython instance
     Py 2.5 (r25:51908, Sep 19 2006, 09:52:17) [MSC v.1310 32 bit (Intel)] IPy 0.7.3b3.r1975
     [ipython]|1> kissa = 444
     [ipython]|2> koira = 555
     [ipython]|3> Exit
     Exited IPython instance!
     New vals: 444 555
 
 Accessing unexposed functionality
 ---------------------------------
 
 There are still many features that are not exposed via the ipapi. If
 you can't avoid using them, you can use the functionality in
 InteractiveShell object (central IPython session class, defined in
 iplib.py) through ip.IP.
 
 For example::
 
     [~]|7> _ip.IP.expand_aliases('np','myfile.py')
        <7> 'c:/opt/Notepad++/notepad++.exe myfile.py'
     [~]|8>
 
 Still, it's preferable that if you encounter such a feature, contact
 the IPython team and request that the functionality be exposed in a
 future version of IPython. Things not in ipapi are more likely to
 change over time.
 
 Provided extensions
 ===================
 
 You can see the list of available extensions (and profiles) by doing
 ``import ipy_<TAB>``. Some extensions don't have the ``ipy_`` prefix in
 module name, so you may need to see the contents of IPython/Extensions
 folder to see what's available.
 
 You can see a brief documentation of an extension by looking at the
 module docstring::
 
     [c:p/ipython_main]|190> import ipy_fsops
     [c:p/ipython_main]|191> ipy_fsops?
 
     ...
 
     Docstring:
         File system operations
 
     Contains: Simple variants of normal unix shell commands (icp, imv, irm,
     imkdir, igrep).
 
 You can also install your own extensions - the recommended way is to
 just copy the module to ~/.ipython. Extensions are typically enabled
 by just importing them (e.g. in ipy_user_conf.py), but some extensions
 require additional steps, for example::
 
     [c:p]|192> import ipy_traits_completer
     [c:p]|193> ipy_traits_completer.activate()    
 
 Note that extensions, even if provided in the stock IPython
 installation, are not guaranteed to have the same requirements as the
 rest of IPython - an extension may require external libraries or a
 newer version of Python than what IPython officially requires. An
 extension may also be under a more restrictive license than IPython
 (e.g. ipy_bzr is under GPL).
 
 Just for reference, the list of bundled extensions at the time of
 writing is below:
 
 astyle.py clearcmd.py envpersist.py ext_rescapture.py ibrowse.py
 igrid.py InterpreterExec.py InterpreterPasteInput.py ipipe.py
 ipy_app_completers.py ipy_autoreload.py ipy_bzr.py ipy_completers.py
 ipy_constants.py ipy_defaults.py ipy_editors.py ipy_exportdb.py
 ipy_extutil.py ipy_fsops.py ipy_gnuglobal.py ipy_kitcfg.py
 ipy_legacy.py ipy_leo.py ipy_p4.py ipy_profile_doctest.py
 ipy_profile_none.py ipy_profile_scipy.py ipy_profile_sh.py
 ipy_profile_zope.py ipy_pydb.py ipy_rehashdir.py ipy_render.py
 ipy_server.py ipy_signals.py ipy_stock_completers.py
 ipy_system_conf.py ipy_traits_completer.py ipy_vimserver.py
 ipy_which.py ipy_workdir.py jobctrl.py ledit.py numeric_formats.py
 PhysicalQInput.py PhysicalQInteractive.py pickleshare.py
 pspersistence.py win32clip.py __init__.py
 
 Reporting bugs
 ==============
 
 Automatic crash reports
 -----------------------
 
 Ideally, IPython itself shouldn't crash. It will catch exceptions
 produced by you, but bugs in its internals will still crash it.
 
 In such a situation, IPython will leave a file named
 IPython_crash_report.txt in your IPYTHONDIR directory (that way if
 crashes happen several times it won't litter many directories, the
 post-mortem file is always located in the same place and new
 occurrences just overwrite the previous one). If you can mail this
 file to the developers (see sec. credits_ for names and addresses), it
 will help us a lot in understanding the cause of the problem and
 fixing it sooner.
 
 
 The bug tracker
 ---------------
 
 IPython also has an online bug-tracker, located at
 http://projects.scipy.org/ipython/ipython/report/1. In addition to
 mailing the developers, it would be a good idea to file a bug report
 here. This will ensure that the issue is properly followed to
 conclusion. To report new bugs you will have to register first.
 
 You can also use this bug tracker to file feature requests.
 
 Brief history
 =============
 
 
 Origins
 -------
 
 The current IPython system grew out of the following three projects:
 
     * [ipython] by Fernando Pérez. I was working on adding
       Mathematica-type prompts and a flexible configuration system
       (something better than $PYTHONSTARTUP) to the standard Python
       interactive interpreter.
     * [IPP] by Janko Hauser. Very well organized, great usability. Had
       an old help system. IPP was used as the 'container' code into
       which I added the functionality from ipython and LazyPython.
     * [LazyPython] by Nathan Gray. Simple but very powerful. The quick
       syntax (auto parens, auto quotes) and verbose/colored tracebacks
       were all taken from here.
 
 When I found out about IPP and LazyPython I tried to join all three
 into a unified system. I thought this could provide a very nice
 working environment, both for regular programming and scientific
 computing: shell-like features, IDL/Matlab numerics, Mathematica-type
 prompt history and great object introspection and help facilities. I
 think it worked reasonably well, though it was a lot more work than I
 had initially planned.
 
 
 Current status
 --------------
 
 The above listed features work, and quite well for the most part. But
 until a major internal restructuring is done (see below), only bug
 fixing will be done, no other features will be added (unless very minor
 and well localized in the cleaner parts of the code).
 
 IPython consists of some 18000 lines of pure python code, of which
 roughly two thirds is reasonably clean. The rest is, messy code which
 needs a massive restructuring before any further major work is done.
 Even the messy code is fairly well documented though, and most of the
 problems in the (non-existent) class design are well pointed to by a
 PyChecker run. So the rewriting work isn't that bad, it will just be
 time-consuming.
 
 
 Future
 ------
 
 See the separate new_design document for details. Ultimately, I would
 like to see IPython become part of the standard Python distribution as a
 'big brother with batteries' to the standard Python interactive
 interpreter. But that will never happen with the current state of the
 code, so all contributions are welcome.

 Credits
 =======
 
 IPython is mainly developed by Fernando Pérez
 <[e-mail]>, but the project was born from mixing in
 Fernando's code with the IPP project by Janko Hauser
 <jhauser-AT-zscout.de> and LazyPython by Nathan Gray
 <n8gray-AT-caltech.edu>. For all IPython-related requests, please
 contact Fernando.
 
 As of early 2006, the following developers have joined the core team:
 
     * [Robert Kern] <rkern-AT-enthought.com>: co-mentored the 2005
       Google Summer of Code project to develop python interactive
       notebooks (XML documents) and graphical interface. This project
       was awarded to the students Tzanko Matev <tsanko-AT-gmail.com> and
       Toni Alatalo <antont-AT-an.org>
     * [Brian Granger] <bgranger-AT-scu.edu>: extending IPython to allow
       support for interactive parallel computing.
     * [Ville Vainio] <vivainio-AT-gmail.com>: Ville is the new
       maintainer for the main trunk of IPython after version 0.7.1.
 
 User or development help should be requested via the IPython mailing lists:
 
 *User list:*
     http://scipy.net/mailman/listinfo/ipython-user 
 *Developer's list:*
     http://scipy.net/mailman/listinfo/ipython-dev 
 
 The IPython project is also very grateful to:
 
 Bill Bumgarner <bbum-AT-friday.com>: for providing the DPyGetOpt module
 which gives very powerful and convenient handling of command-line
 options (light years ahead of what Python 2.1.1's getopt module does).
 
 Ka-Ping Yee <ping-AT-lfw.org>: for providing the Itpl module for
 convenient and powerful string interpolation with a much nicer syntax
 than formatting through the '%' operator.
 
 Arnd Baecker <baecker-AT-physik.tu-dresden.de>: for his many very useful
 suggestions and comments, and lots of help with testing and
 documentation checking. Many of IPython's newer features are a result of
 discussions with him (bugs are still my fault, not his).
 
 Obviously Guido van Rossum and the whole Python development team, that
 goes without saying.
 
 IPython's website is generously hosted at http://ipython.scipy.orgby
 Enthought (http://www.enthought.com). I am very grateful to them and all
 of the SciPy team for their contribution.
 
 Fernando would also like to thank Stephen Figgins <fig-AT-monitor.net>,
 an O'Reilly Python editor. His Oct/11/2001 article about IPP and
 LazyPython, was what got this project started. You can read it at:
 http://www.onlamp.com/pub/a/python/2001/10/11/pythonnews.html.
