2007-03-02  J�rgen 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).
