[phone]  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
