doc/ChangeLog

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 aobut 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 and 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 move 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 banches/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 kee 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 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
	misteriously, 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 hadnle 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 top 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-dev about it (F. Mantegazza may use them).

2005-07-29  Fernando Perez  <[e-mail]>

	* 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 in
