+IDLEfork ChangeLog
+==================
+
+2001-07-20 11:35  elguavas
+
+	* README.txt, NEWS.txt: bring up to date for 0.8.1 release
+
+2001-07-19 16:40  elguavas
+
+	* IDLEFORK.html: replaced by IDLEFORK-index.html
+
+2001-07-19 16:39  elguavas
+
+	* IDLEFORK-index.html: updated placeholder idlefork homepage
+
+2001-07-19 14:49  elguavas
+
+	* ChangeLog, EditorWindow.py, INSTALLATION, NEWS.txt, README.txt,
+	TODO.txt, idlever.py:
+	minor tidy-ups ready for 0.8.1 alpha tarball release
+
+2001-07-17 15:12  kbk
+
+	* INSTALLATION, setup.py: INSTALLATION: Remove the coexist.patch
+	instructions
+
+	**************** setup.py:
+
+	Remove the idles script, add some words on IDLE Fork to the
+	long_description, and clean up some line spacing.
+
+2001-07-17 15:01  kbk
+
+	* coexist.patch: Put this in the attic, at least for now...
+
+2001-07-17 14:59  kbk
+
+	* PyShell.py, idle, idles: Implement idle command interface as
+	suggested by GvR [idle-dev] 16 July **************** PyShell: Added
+	functionality:
+
+	usage: idle.py [-c command] [-d] [-i] [-r script] [-s] [-t title]
+	[arg] ...
+
+	idle file(s)	(without options) edit the file(s)
+
+	-c cmd	   run the command in a shell -d	 enable the
+	debugger -i	    open an interactive shell -i file(s) open a
+	shell and also an editor window for each file -r script  run a file
+	as a script in a shell -s	  run $IDLESTARTUP or
+	$PYTHONSTARTUP before anything else -t title   set title of shell
+	window
+
+	Remaining arguments are applied to the command (-c) or script (-r).
+
+	****************** idles: Removed the idles script, not needed
+
+	****************** idle:  Removed the IdleConf references, not
+	required anymore
+
+2001-07-16 17:08  kbk
+
+	* INSTALLATION, coexist.patch: Added installation instructions.
+
+	Added a patch which modifies idlefork so that it can co-exist with
+	"official" IDLE in the site-packages directory. This patch is not
+	necessary if only idlefork IDLE is installed. See INSTALLATION for
+	further details.
+
+2001-07-16 15:50  kbk
+
+	* idles: Add a script "idles" which opens a Python Shell window.
+
+	The default behaviour of idlefork idle is to open an editor window
+	instead of a shell. Complex expressions may be run in a fresh
+	environment by selecting "run".  There are times, however, when a
+	shell is desired.  Though one can be started by "idle -t 'foo'",
+	this script is more convenient.  In addition, a shell and an editor
+	window can be started in parallel by "idles -e foo.py".
+
+2001-07-16 15:25  kbk
+
+	* PyShell.py: Call out IDLE Fork in startup message.
+
+2001-07-16 14:00  kbk
+
+	* PyShell.py, setup.py: Add a script "idles" which opens a Python
+	Shell window.

+
+2001-07-15 03:06  kbk
+
+	* pyclbr.py, tabnanny.py: tabnanny and pyclbr are now found in /Lib
+
+2001-07-15 02:29  kbk
+
+	* BrowserControl.py: Remove, was retained for 1.5.2 support
+
+2001-07-14 15:48  kbk
+
+	* setup.py: Installing Idle to site-packages via Distutils does not
+	copy the Idle help.txt file.
+
+	Ref SF Python Patch 422471
+
+2001-07-14 15:26  kbk
+
+	* keydefs.py: py-cvs-2001_07_13 (Rev 1.3) merge
+
+	"Make copy, cut and paste events case insensitive.  Reported by
+	Patrick K. O'Brien on idle-dev. (Should other bindings follow
+	suit?)" --GvR
+
+2001-07-14 15:21  kbk
+
+	* idle.py: py-cvs-2001_07_13 (Rev 1.4) merge
+
+	"Move the action of loading the configuration to the IdleConf
+	module rather than the idle.py script.	This has advantages and
+	disadvantages; the biggest advantage being that we can more easily
+	have an alternative main program."  --GvR
+
+2001-07-14 15:18  kbk
+
+	* extend.txt: py-cvs-2001_07_13 (Rev 1.4) merge
+
+	"Quick update to the extension mechanism (extend.py is gone, long
+	live config.txt)" --GvR
+
+2001-07-14 15:15  kbk
+
+	* StackViewer.py: py-cvs-2001_07_13 (Rev 1.16) merge
+
+	"Refactored, with some future plans in mind. This now uses the new
+	gotofileline() method defined in FileList.py"  --GvR
+
+2001-07-14 15:10  kbk
+
+	* PyShell.py: py-cvs-2001_07_13 (Rev 1.34) merge
+
+	"Amazing.  A very subtle change in policy in descr-branch actually
+	found a bug here.  Here's the deal: Class PyShell derives from
+	class OutputWindow.  Method PyShell.close() wants to invoke its
+	parent method, but because PyShell long ago was inherited from
+	class PyShellEditorWindow, it invokes
+	PyShelEditorWindow.close(self).  Now, class PyShellEditorWindow
+	itself derives from class OutputWindow, and inherits the close()
+	method from there without overriding it.  Under the old rules,
+	PyShellEditorWindow.close would return an unbound method restricted
+	to the class that defined the implementation of close(), which was
+	OutputWindow.close.  Under the new rules, the unbound method is
+	restricted to the class whose method was requested, that is
+	PyShellEditorWindow, and this was correctly trapped as an error."
+	--GvR
+
+2001-07-14 14:59  kbk
+
+	* PyParse.py: py-cvs-2001_07_13 (Rel 1.9) merge
+
+	"Taught IDLE's autoident parser that "yield" is a keyword that
+	begins a stmt.	Along w/ the preceding change to keyword.py, making
+	all this work w/ a future-stmt just looks harder and harder."
+	--tim_one
+
+	(From Rel 1.8: "Hack to make this still work with Python 1.5.2.
+	;-( " --fdrake)
+
+2001-07-14 14:51  kbk
+
+	* IdleConf.py: py-cvs-2001_07_13 (Rel 1.7) merge
+
+	"Move the action of loading the configuration to the IdleConf
+	module rather than the idle.py script.	This has advantages and
+	disadvantages; the biggest advantage being that we can more easily
+	have an alternative main program." --GvR
+
+2001-07-14 14:45  kbk
+
+	* FileList.py: py-cvs-2000_07_13 (Rev 1.9) merge
+
+	"Delete goodname() method, which is unused. Add gotofileline(), a
+	convenience method which I intend to use in a variant. Rename
+	test() to _test()."  --GvR
+
+	This was an interesting merge. The join completely missed removing
+	goodname(), which was adjacent, but outside of, a small conflict.
+	I only caught it by comparing the 1.1.3.2/1.1.3.3 diff.  CVS ain't
+	infallible.
+
+2001-07-14 13:58  kbk
+
+	* EditorWindow.py: py-cvs-2000_07_13 (Rev 1.38) merge "Remove
+	legacy support for the BrowserControl module; the webbrowser module
+	has been included since Python 2.0, and that is the preferred
+	interface." --fdrake
+
+2001-07-14 13:32  kbk
+
+	* EditorWindow.py, FileList.py, IdleConf.py, PyParse.py,
+	PyShell.py, StackViewer.py, extend.txt, idle.py, keydefs.py: Import
+	the 2001 July 13 23:59 GMT version of Python CVS IDLE on the
+	existing 1.1.3 vendor branch named py-cvs-vendor-branch. Release
+	tag is py-cvs-2001_07_13.

+
+	VP IDLE version depended on VP's ExecBinding.py and spawn.py to get
+	the path to the Windows Doc directory (relative to python.exe).
+	Removed this conflicting code in favor of py-cvs updates which on
+	Windows use a hard coded path relative to the location of this
+	module. py-cvs updates include support for webbrowser.py.  Module
+	still has BrowserControl.py for 1.5.2 support.
+
+	At this point, the differences wrt py-cvs relate to menu
+	functionality.

+original IDLE ChangeLog:
+========================
+
+Tue Feb 15 18:08:19 2000  Guido van Rossum  <guido@cnri.reston.va.us>
+
+	* NEWS.txt: Notice status bar and stack viewer.
+
+	* EditorWindow.py: Support for Moshe's status bar.
+
+	* MultiStatusBar.py: Status bar code -- by Moshe Zadka.
+
+	* OldStackViewer.py:
+	Adding the old stack viewer implementation back, for the debugger.
+
+	* StackViewer.py: New stack viewer, uses a tree widget.
+	(XXX: the debugger doesn't yet use this.)
+
+	* WindowList.py:
+	Correct a typo and remove an unqualified except that was hiding the error.
+
+	* ClassBrowser.py: Add an XXX comment about the ClassBrowser AIP.
+
+	* ChangeLog: Updated change log.
+
+	* NEWS.txt: News update.  Probably incomplete; what else is new?
+
+	* README.txt:
+	Updated for pending IDLE 0.5 release (still very rough -- just getting
+	it out in a more convenient format than CVS).
+
+	* TODO.txt: Tiny addition.
+
+Thu Sep  9 14:16:02 1999  Guido van Rossum  <guido@cnri.reston.va.us>
+
+	* TODO.txt: A few new TODO entries.
+
+Thu Aug 26 23:06:22 1999  Guido van Rossum  <guido@cnri.reston.va.us>
+
+	* Bindings.py: Add Python Documentation entry to Help menu.
+
+	* EditorWindow.py:
+	Find the help.txt file relative to __file__ or ".", not in sys.path.
+	(Suggested by Moshe Zadka, but implemented differently.)
+
+	Add <<python-docs>> event which, on Unix, brings up Netscape pointing
+	to http://www.python.doc/current/ (a local copy would be nice but its
+	location can't be predicted).  Windows solution TBD.
+
+Wed Aug 11 14:55:43 1999  Guido van Rossum  <guido@cnri.reston.va.us>
+
+	* TreeWidget.py:
+	Moshe noticed an inconsistency in his comment, so I'm rephrasing it to
+	be clearer.
+
+	* TreeWidget.py:
+	Patch inspired by Moshe Zadka to search for the Icons directory in the
+	same directory as __file__, rather than searching for it along sys.path.
+	This works better when idle is a package.
+
+Thu Jul 15 13:11:02 1999  Guido van Rossum  <guido@cnri.reston.va.us>
+
+	* TODO.txt: New wishes.
+
+Sat Jul 10 13:17:35 1999  Guido van Rossum  <guido@cnri.reston.va.us>
+
+	* IdlePrefs.py:
+	Make the color for stderr red (i.e. the standard warning/danger/stop
+	color) rather than green.  Suggested by Sam Schulenburg.
+
+Fri Jun 25 17:26:34 1999  Guido van Rossum  <guido@cnri.reston.va.us>
+
+	* PyShell.py: Close debugger when closing.  This may break a cycle.
+
+	* Debugger.py: Break cycle on close.
+
+	* ClassBrowser.py: Destroy the tree when closing.
+
+	* TreeWidget.py: Add destroy() method to recursively destroy a tree.
+
+	* PyShell.py: Extend _close() to break cycles.
+	Break some other cycles too (and destroy the root when done).
+
+	* EditorWindow.py:
+	Add _close() method that does the actual cleanup (close() asks the
+	user what they want first if there's unsaved stuff, and may cancel).
+	It closes more than before.
+
+	Add unload_extensions() method to unload all extensions; called from
+	_close().  It calls an extension's close() method if it has one.
+
+	* Percolator.py: Add close() method that breaks cycles.
+
+	* WidgetRedirector.py: Add unregister() method.
+	Unregister everything at closing.
+	Don't call close() in __del__, rely on explicit call to close().
+
+	* IOBinding.py, FormatParagraph.py, CallTips.py:
+	Add close() method that breaks a cycle.
+
+Fri Jun 11 15:03:00 1999  Guido van Rossum  <guido@cnri.reston.va.us>
+
+	* AutoIndent.py, EditorWindow.py, FormatParagraph.py:
+	Tim Peters smart.patch:
+
+	EditorWindow.py:
+
+	+ Added get_tabwidth & set_tabwidth "virtual text" methods, that get/set the
+	widget's view of what a tab means.
+
+	+ Moved TK_TABWIDTH_DEFAULT here from AutoIndent.
+
+	+ Renamed Mark's get_selection_index to get_selection_indices (sorry, Mark,
+	but the name was plain wrong <wink>).
+
+	FormatParagraph.py:  renamed use of get_selection_index.
+
+	AutoIndent.py:
+
+	+ Moved TK_TABWIDTH_DEFAULT to EditorWindow.
+
+	+ Rewrote set_indentation_params to use new VTW get/set_tabwidth methods.
+
+	+ Changed smart_backspace_event to delete whitespace back to closest
+	preceding virtual tab stop or real character (note that this may require
+	inserting characters if backspacing over a tab!).
+
+	+ Nuked almost references to the selection tag, in favor of using
+	get_selection_indices.  The sole exception is in set_region, for which no
+	"set_selection" abstraction has yet been agreed upon.
+
+	+ Had too much fun using the spiffy new features of the format-paragraph
+	cmd.
+
+Thu Jun 10 17:48:02 1999  Guido van Rossum  <guido@cnri.reston.va.us>
+
+	* FormatParagraph.py:
+	Code by Mark Hammond to format paragraphs embedded in comments.
+	Read the comments (which I reformatted using the new feature :-)
+	for some limitations.
+
+	* EditorWindow.py:
+	Added abstraction get_selection_index() (Mark Hammond).  Also
+	reformatted some comment blocks to show off a cool feature I'm about
+	to check in next.
+
+	* ClassBrowser.py:
+	Adapt to the new pyclbr's support of listing top-level functions.  If
+	this functionality is not present (e.g. when used with a vintage
+	Python 1.5.2 installation) top-level functions are not listed.
+
+	(Hmm...  Any distribution of IDLE 0.5 should probably include a copy
+	of the new pyclbr.py!)
+
+	* AutoIndent.py:
+	Fix off-by-one error in Tim's recent change to comment_region(): the
+	list of lines returned by get_region() contains an empty line at the
+	end representing the start of the next line, and this shouldn't be
+	commented out!
+
+	* CallTips.py:
+	Mark Hammond writes: Here is another change that allows it to work for
+	class creation - tries to locate an __init__ function.  Also updated
+	the test code to reflect your new "***" change.
+
+	* CallTipWindow.py:
+	Mark Hammond writes: Tim's suggestion of copying the font for the
+	CallTipWindow from the text control makes sense, and actually makes
+	the control look better IMO.
+
+Wed Jun  9 20:34:57 1999  Guido van Rossum  <guido@cnri.reston.va.us>
+
+	* CallTips.py:
+	Append "..." if the appropriate flag (for varargs) in co_flags is set.
+	Ditto "***" for kwargs.
+
+Tue Jun  8 13:06:07 1999  Guido van Rossum  <guido@cnri.reston.va.us>
+
+	* ReplaceDialog.py:
+	Hmm...  Tim didn't turn "replace all" into a single undo block.
+	I think I like it better if it os, so here.
+
+	* ReplaceDialog.py: Tim Peters: made replacement atomic for undo/redo.
+
+	* AutoIndent.py: Tim Peters:
+
+	+ Set usetabs=1.  Editing pyclbr.py was driving me nuts <0.6 wink>.
+	usetabs=1 is the Emacs pymode default too, and thanks to indentwidth !=
+	tabwidth magical usetabs disabling, new files are still created with tabs
+	turned off.  The only implication is that if you open a file whose first
+	indent is a single tab, IDLE will now magically use tabs for that file (and
+	set indentwidth to 8).  Note that the whole scheme doesn't work right for
+	PythonWin, though, since Windows users typically set tabwidth to 4; Mark
+	probably has to hide the IDLE algorithm from them (which he already knows).
+
+	+ Changed comment_region_event to stick "##" in front of every line.  The
+	"holes" previously left on blank lines were visually confusing (made it
+	needlessly hard to figure out what to uncomment later).
+
+Mon Jun  7 15:38:40 1999  Guido van Rossum  <guido@cnri.reston.va.us>
+
+	* TreeWidget.py, ObjectBrowser.py:
+	Remove unnecessary reference to pyclbr from test() code.
+
+	* PyParse.py: Tim Peters:
+
+	Smarter logic for finding a parse synch point.
+
+	Does a half to a fifth the work in normal cases; don't notice the speedup,
+	but makes  more breathing room for other extensions.
+
+	Speeds terrible cases by at least a factor of 10. "Terrible" == e.g. you put
+	""" at the start of Tkinter.py, undo it, zoom to the bottom, and start
+	typing in code.  Used to take about 8 seconds for ENTER to respond, now some
+	large fraction of a second.  The new code gets indented correctly, despite
+	that it all remains "string colored" until the colorizer catches up (after
+	which, ENTER appears instantaneous again).
+
+Fri Jun  4 19:21:19 1999  Guido van Rossum  <guido@cnri.reston.va.us>
+
+	* extend.py: Might as well enable CallTips by default.
+	If there are too many complaints I'll remove it again or fix it.
+
+Thu Jun  3 14:32:16 1999  Guido van Rossum  <guido@cnri.reston.va.us>
+
+	* AutoIndent.py, EditorWindow.py, PyParse.py:
+	New offerings by Tim Peters; he writes:
+
+	IDLE is now the first Python editor in the Universe not confused by my
+	doctest.py <wink>.
+
+	As threatened, this defines IDLE's is_char_in_string function as a
+	method of EditorWindow.  You just need to define one similarly in
+	whatever it is you pass as editwin to AutoIndent; looking at the
+	EditorWindow.py part of the patch should make this clear.
+
+	* GrepDialog.py: Enclose pattern in quotes in status message.
+
+	* CallTips.py:
+	Mark Hammond fixed some comments and improved the way the tip text is
+	constructed.
+
+Wed Jun  2 18:18:57 1999  Guido van Rossum  <guido@cnri.reston.va.us>
+
+	* CallTips.py:
+	My fix to Mark's code: restore the universal check on <KeyRelease>.
+	Always cancel on <Key-Escape> or <ButtonPress>.
+
+	* CallTips.py:
+	A version that Mark Hammond posted to the newsgroup.  Has some newer
+	stuff for getting the tip.  Had to fix the Key-( and Key-) events
+	for Unix.  Will have to re-apply my patch for catching KeyRelease and
+	ButtonRelease events.
+
+	* CallTipWindow.py, CallTips.py:
+	Call tips by Mark Hammond (plus tiny fix by me.)
+
+	* IdleHistory.py:
+	Changes by Mark Hammond: (1) support optional output_sep argument to
+	the constructor so he can eliminate the sys.ps2 that PythonWin leaves
+	in the source; (2) remove duplicate history items.
+
+	* AutoIndent.py:
+	Changes by Mark Hammond to allow using IDLE extensions in PythonWin as
+	well: make three dialog routines instance variables.
+
+	* EditorWindow.py:
+	Change by Mark Hammond to allow using IDLE extensions in PythonWin as
+	well: make three dialog routines instance variables.
+
+Tue Jun  1 20:06:44 1999  Guido van Rossum  <guido@cnri.reston.va.us>
+
+	* AutoIndent.py: Hah!  A fix of my own to Tim's code!
+	Unix bindings for <<toggle-tabs>> and <<change-indentwidth>> were
+	missing, and somehow that meant the events were never generated,
+	even though they were in the menu.  The new Unix bindings are now
+	the same as the Windows bindings (M-t and M-u).
+
+	* AutoIndent.py, PyParse.py, PyShell.py: Tim Peters again:
+
+	The new version (attached) is fast enough all the time in every real module
+	I have <whew!>.  You can make it slow by, e.g., creating an open list with
+	5,000 90-character identifiers (+ trailing comma) each on its own line, then
+	adding an item to the end -- but that still consumes less than a second on
+	my P5-166.  Response time in real code appears instantaneous.
+
+	Fixed some bugs.
+
+	New feature:  when hitting ENTER and the cursor is beyond the line's leading
+	indentation, whitespace is removed on both sides of the cursor; before
+	whitespace was removed only on the left; e.g., assuming the cursor is
+	between the comma and the space:
+
+	def something(arg1, arg2):
+	                   ^ cursor to the left of here, and hit ENTER
+	               arg2):   # new line used to end up here
+	              arg2):    # but now lines up the way you expect
+
+	New hack:  AutoIndent has grown a context_use_ps1 Boolean config option,
+	defaulting to 0 (false) and set to 1 (only) by PyShell.  Reason:  handling
+	the fancy stuff requires looking backward for a parsing synch point; ps1
+	lines are the only sensible thing to look for in a shell window, but are a
+	bad thing to look for in a file window (ps1 lines show up in my module
+	docstrings often).  PythonWin's shell should set this true too.
+
+	Persistent problem:  strings containing def/class can still screw things up
+	completely.  No improvement.  Simplest workaround is on the user's head, and
+	consists of inserting e.g.
+
+	def _(): pass
+
+	(or any other def/class) after the end of the multiline string that's
+	screwing them up.  This is especially irksome because IDLE's syntax coloring
+	is *not* confused, so when this happens the colors don't match the
+	indentation behavior they see.
+
+	* AutoIndent.py: Tim Peters again:
+
+	[Tim, after adding some bracket smarts to AutoIndent.py]
+	> ...
+	> What it can't possibly do without reparsing large gobs of text is
+	> suggest a reasonable indent level after you've *closed* a bracket
+	> left open on some previous line.
+	> ...
+
+	The attached can, and actually fast enough to use -- most of the time.  The
+	code is tricky beyond belief to achieve that, but it works so far; e.g.,
+
+	        return len(string.expandtabs(str[self.stmt_start :
+	                                         ^ indents to caret
+	                                         i],
+	                                     ^ indents to caret
+	                                     self.tabwidth)) + 1
+	    ^ indents to caret
+
+	It's about as smart as pymode now, wrt both bracket and backslash
+	continuation rules.  It does require reparsing large gobs of text, and if it
+	happens to find something that looks like a "def" or "class" or sys.ps1
+	buried in a multiline string, but didn't suck up enough preceding text to
+	see the start of the string, it's completely hosed.  I can't repair that --
+	it's just too slow to reparse from the start of the file all the time.
+
+	AutoIndent has grown a new num_context_lines tuple attribute that controls
+	how far to look back, and-- like other params --this could/should be made
+	user-overridable at startup and per-file on the fly.
+
+	* PyParse.py: New file by Tim Peters:
+
+	One new file in the attached, PyParse.py.  The LineStudier (whatever it was
+	called <wink>) class was removed from AutoIndent; PyParse subsumes its
+	functionality.
+
+	* AutoIndent.py: Tim Peters keeps revising this module (more to come):
+
+	Removed "New tabwidth" menu binding.
+
+	Added "a tab means how many spaces?" dialog to block tabify and untabify.  I
+	think prompting for this is good now:  they're usually at-most-once-per-file
+	commands, and IDLE can't let them change tabwidth from the Tk default
+	anymore, so IDLE can no longer presume to have any idea what a tab means.
+
+	Irony:  for the purpose of keeping comments aligned via tabs, Tk's
+	non-default approach is much nicer than the Emacs/Notepad/Codewright/vi/etc
+	approach.
+
+	* EditorWindow.py:
+	1. Catch NameError on import (could be raised by case mismatch on Windows).
+	2. No longer need to reset pyclbr cache and show watch cursor when calling
+	   ClassBrowser -- the ClassBrowser takes care of pyclbr and the TreeWidget
+	   takes care of the watch cursor.
+	3. Reset the focus to the current window after error message about class
+	   browser on buffer without filename.
+
+	* Icons/minusnode.gif, Icons/plusnode.gif: Missed a few.
+
+	* ClassBrowser.py, PathBrowser.py: Rewritten based on TreeWidget.py
+
+	* ObjectBrowser.py: Object browser, based on TreeWidget.py.
+
+	* TreeWidget.py: Tree widget done right.
+
+	* ToolTip.py: As yet unused code for tool tips.
+
+	* ScriptBinding.py:
+	Ensure sys.argv[0] is the script name on Run Script.
+
+	* ZoomHeight.py: Move zoom height functionality to separate function.
+
+	* Icons/folder.gif, Icons/openfolder.gif, Icons/python.gif, Icons/tk.gif:
+	A few icons used by ../TreeWidget.py and its callers.
+
+	* AutoIndent.py: New version by Tim Peters improves block opening test.
+
+Fri May 21 04:46:17 1999  Guido van Rossum  <guido@cnri.reston.va.us>
+
+	* Attic/History.py, PyShell.py: Rename History to IdleHistory.
+	Add isatty() to pseudo files.
+
+	* StackViewer.py: Make initial stack viewer wider
+
+	* TODO.txt: New wishes
+
+	* AutoIndent.py, EditorWindow.py, PyShell.py:
+	Much improved autoindent and handling of tabs,
+	by Tim Peters.
+
+Mon May  3 15:49:52 1999  Guido van Rossum  <guido@cnri.reston.va.us>
+
+	* AutoIndent.py, EditorWindow.py, FormatParagraph.py, UndoDelegator.py:
+	Tim Peters writes:
+
+	I'm still unsure, but couldn't stand the virtual event trickery so tried a
+	different sin (adding undo_block_start/stop methods to the Text instance in
+	EditorWindow.py).  Like it or not, it's efficient and works <wink>.  Better
+	idea?
+
+	Give the attached a whirl.  Even if you hate the implementation, I think
+	you'll like the results.  Think I caught all the "block edit" cmds,
+	including Format Paragraph, plus subtler ones involving smart indents and
+	backspacing.
+
+	* WidgetRedirector.py: Tim Peters writes:
+
+	[W]hile trying to dope out how redirection works, stumbled into two
+	possible glitches.  In the first, it doesn't appear to make sense to try to
+	rename a command that's already been destroyed; in the second, the name
+	"previous" doesn't really bring to mind "ignore the previous value" <wink>.
+
+Fri Apr 30 19:39:25 1999  Guido van Rossum  <guido@cnri.reston.va.us>
+
+	* __init__.py: Support for using idle as a package.
+
+	* PathBrowser.py:
+	Avoid listing files more than once (e.g. foomodule.so has two hits:
+	once for foo + module.so, once for foomodule + .so).
+
+Mon Apr 26 22:20:38 1999  Guido van Rossum  <guido@cnri.reston.va.us>
+
+	* ChangeLog, ColorDelegator.py, PyShell.py: Tim Peters strikes again:
+
+	Ho ho ho -- that's trickier than it sounded!  The colorizer is working with
+	"line.col" strings instead of Text marks, and the absolute coordinates of
+	the point of interest can change across the self.update call (voice of
+	baffled experience, when two quick backspaces no longer fooled it, but a
+	backspace followed by a quick ENTER did <wink>).
+
+	Anyway, the attached appears to do the trick.  CPU usage goes way up when
+	typing quickly into a long triple-quoted string, but the latency is fine for
+	me (a relatively fast typist on a relatively slow machine).  Most of the
+	changes here are left over from reducing the # of vrbl names to help me
+	reason about the logic better; I hope the code is a *little* easier to
+
+Fri Apr 23 14:01:25 1999  Guido van Rossum  <guido@cnri.reston.va.us>
+
+	* EditorWindow.py:
+	Provide full arguments to __import__ so it works in packagized IDLE.
+
+Thu Apr 22 23:20:17 1999  Guido van Rossum  <guido@cnri.reston.va.us>
+
+        * help.txt:
+        Bunch of updates necessary due to recent changes; added docs for File
+        menu, command line and color preferences.
+
+        * Bindings.py: Remove obsolete 'script' menu.
+
+	* TODO.txt: Several wishes fulfilled.
+
+	* OutputWindow.py:
+	Moved classes OnDemandOutputWindow and PseudoFile here,
+	from ScriptBinding.py where they are no longer needed.
+
+	* ScriptBinding.py:
+	Mostly rewritten.  Instead of the old Run module and Debug module,
+	there are two new commands:
+
+	Import module (F5) imports or reloads the module and also adds its
+	name to the __main__ namespace.  This gets executed in the PyShell
+	window under control of its debug settings.
+
+	Run script (Control-F5) is similar but executes the contents of the
+	file directly in the __main__ namespace.
+
+	* PyShell.py: Nits: document use of $IDLESTARTUP; display idle version
+
+	* idlever.py: New version to celebrate new command line
+
+	* OutputWindow.py: Added flush(), for completeness.
+
+	* PyShell.py:
+	A lot of changes to make the command line more useful.  You can now do:
+	  idle.py -e file ...    -- to edit files
+	  idle.py script arg ... -- to run a script
+	  idle.py -c cmd arg ... -- to run a command
+	Other options, see also the usage message (also new!) for more details:
+	  -d       -- enable debugger
+	  -s       -- run $IDLESTARTUP or $PYTHONSTARTUP
+	  -t title -- set Python Shell window's title
+	sys.argv is set accordingly, unless -e is used.
+	sys.path is absolutized, and all relevant paths are inserted into it.
+
+	Other changes:
+	- the environment in which commands are executed is now the
+	  __main__ module
+	- explicitly save sys.stdout etc., don't restore from sys.__stdout__
+	- new interpreter methods execsource(), execfile(), stuffsource()
+	- a few small nits
+
+	* TODO.txt:
+	Some more TODO items.  Made up my mind about command line args,
+	Run/Import, __main__.
+
+	* ColorDelegator.py:
+	Super-elegant patch by Tim Peters that speeds up colorization
+	dramatically (up to 15 times he claims).  Works by reading more than
+	one line at a time, up to 100-line chunks (starting with one line and
+	then doubling up to the limit).  On a typical machine (e.g. Tim's
+	P5-166) this doesn't reduce interactive responsiveness in a noticeable
+	way.
+
+Wed Apr 21 15:49:34 1999  Guido van Rossum  <guido@cnri.reston.va.us>
+
+	* ColorDelegator.py:
+	Patch by Tim Peters to speed up colorizing of big multiline strings.
+
+Tue Apr 20 17:32:52 1999  Guido van Rossum  <guido@cnri.reston.va.us>
+
+	* extend.txt:
+	For an event 'foo-bar', the corresponding method must be called
+	foo_bar_event().  Therefore, fix the references to zoom_height() in
+	the example.
+
+	* IdlePrefs.py: Restored the original IDLE color scheme.
+
+	* PyShell.py, IdlePrefs.py, ColorDelegator.py, EditorWindow.py:
+	Color preferences code by Loren Luke (massaged by me somewhat)
+
+	* SearchEngine.py:
+	Patch by Mark Favas: it fixes the search engine behaviour where an
+	unsuccessful search wraps around and re-searches that part of the file
+	between the start of the search and the end of the file - only really
+	an issue for very large files, but... (also removes a redundant
+	m.span() call).
+
+Mon Apr 19 16:26:02 1999  Guido van Rossum  <guido@cnri.reston.va.us>
+
+	* TODO.txt: A few wishes are now fulfilled.
+
+	* AutoIndent.py: Tim Peters implements some of my wishes:
+
+	o Makes the tab key intelligently insert spaces when appropriate
+	(see Help list banter twixt David Ascher and me; idea stolen from
+	every other editor on earth <wink>).
+
+	o newline_and_indent_event trims trailing whitespace on the old
+	line (pymode and Codewright).
+
+	o newline_and_indent_event no longer fooled by trailing whitespace or
+	comment after ":" (pymode, PTUI).
+
+	o newline_and_indent_event now reduces the new line's indentation after
+	return, break, continue, raise and pass stmts (pymode).
+
+	The last two are easy to fool in the presence of strings &
+	continuations, but pymode requires Emacs's high-powered C parsing
+	functions to avoid that in finite time.
+
+======================================================================
+	Python release 1.5.2c1, IDLE version 0.4
+======================================================================
+
+Wed Apr  7 18:41:59 1999  Guido van Rossum  <guido@cnri.reston.va.us>
+
+	* README.txt, NEWS.txt: New version.
+
+	* idlever.py: Version bump awaiting impending new release.
+	(Not much has changed :-( )
+
+Mon Mar 29 14:52:28 1999  Guido van Rossum  <guido@cnri.reston.va.us>
+
+	* ScriptBinding.py, PyShell.py:
+	At Tim Peters' recommendation, add a dummy flush() method to
+	PseudoFile.
+
+Thu Mar 11 23:21:23 1999  Guido van Rossum  <guido@cnri.reston.va.us>
+
+	* PathBrowser.py: Don't crash when sys.path contains an empty string.
+
+	* Attic/Outline.py: This file was never supposed to be part of IDLE.
+
+	* PathBrowser.py:
+	- Don't crash in the case where a superclass is a string instead of a
+	pyclbr.Class object; this can happen when the superclass is
+	unrecognizable (to pyclbr), e.g. when module renaming is used.
+
+	- Show a watch cursor when calling pyclbr (since it may take a while
+	recursively parsing imported modules!).
+
+Wed Mar 10 05:18:02 1999  Guido van Rossum  <guido@cnri.reston.va.us>
+
+	* EditorWindow.py, Bindings.py: Add PathBrowser to File module
+
+	* PathBrowser.py: "Path browser" - 4 scrolled lists displaying:
+	    directories on sys.path
+	    modules in selected directory
+	    classes in selected module
+	    methods of selected class
+
+	Single clicking in a directory, module or class item updates the next
+	column with info about the selected item.  Double clicking in a
+	module, class or method item opens the file (and selects the clicked
+	item if it is a class or method).
+
+	I guess eventually I should be using a tree widget for this, but the
+	ones I've seen don't work well enough, so for now I use the old
+	Smalltalk or NeXT style multi-column hierarchical browser.
+
+	* MultiScrolledLists.py:
+	New utility: multiple scrolled lists in parallel
+
+	* ScrolledList.py: - White background.
+	- Display "(None)" (or text of your choosing) when empty.
+	- Don't set the focus.
+

+======================================================================
+
+Wed Feb 17 22:47:41 1999  Guido van Rossum  <guido@cnri.reston.va.us>
+
+	* NEWS.txt: News in 0.3.
+
+	* README.txt, idlever.py: Bump version to 0.3.
+
+	* EditorWindow.py:
+	After all, we don't need to call the callbacks ourselves!
+
+	* WindowList.py:
+	When deleting, call the callbacks *after* deleting the window from our list!
+
+	* EditorWindow.py:
+	Fix up the Windows menu via the new callback mechanism instead of
+	depending on menu post commands (which don't work when the menu is
+	torn off).
+
+	* WindowList.py:
+	Support callbacks to patch up Windows menus everywhere.
+
+	* ChangeLog: Oh, why not.  Checking in the Emacs-generated change log.
+
+Tue Feb 16 22:34:17 1999  Guido van Rossum  <guido@cnri.reston.va.us>
+
+	* ScriptBinding.py:
+	Only pop up the stack viewer when requested in the Debug menu.
+
+Mon Feb  8 22:27:49 1999  Guido van Rossum  <guido@cnri.reston.va.us>
+
+	* WindowList.py: Don't crash if a window no longer exists.
+
+	* TODO.txt: Restructured a bit.
+
+Mon Feb  1 23:06:17 1999  Guido van Rossum  <guido@cnri.reston.va.us>
+
+	* PyShell.py: Add current dir or paths of file args to sys.path.
+
+	* Debugger.py: Add canonic() function -- for brand new bdb.py feature.
+
+	* StackViewer.py: Protect against accessing an empty stack.
+
+Fri Jan 29 20:44:45 1999  Guido van Rossum  <guido@cnri.reston.va.us>
+
+	* ZoomHeight.py:
+	Use only the height to decide whether to zoom in or out.
+
+Thu Jan 28 22:24:30 1999  Guido van Rossum  <guido@cnri.reston.va.us>
+
+	* EditorWindow.py, FileList.py:
+	Make sure the Tcl variables are shared between windows.
+
+	* PyShell.py, EditorWindow.py, Bindings.py:
+	Move menu/key binding code from Bindings.py to EditorWindow.py,
+	with changed APIs -- it makes much more sense there.
+	Also add a new feature: if the first character of a menu label is
+	a '!', it gets a checkbox.  Checkboxes are bound to Boolean Tcl variables
+	that can be accessed through the new getvar/setvar/getrawvar API;
+	the variable is named after the event to which the menu is bound.
+
+	* Debugger.py: Add Quit button to the debugger window.
+
+	* SearchDialog.py:
+	When find_again() finds exactly the current selection, it's a failure.
+
+	* idle.py, Attic/idle: Rename idle -> idle.py
+
+Mon Jan 18 15:18:57 1999  Guido van Rossum  <guido@cnri.reston.va.us>
+
+	* EditorWindow.py, WindowList.py: Only deiconify when iconic.
+
+	* TODO.txt: Misc
+
+Tue Jan 12 22:14:34 1999  Guido van Rossum  <guido@cnri.reston.va.us>
+
+	* testcode.py, Attic/test.py:
+	Renamed test.py to testcode.py so one can import Python's
+	test package from inside IDLE.  (Suggested by Jack Jansen.)
+
+	* EditorWindow.py, ColorDelegator.py:
+	Hack to close a window that is colorizing.
+
+	* Separator.py: Vladimir Marangozov's patch:
+	The separator dances too much and seems to jump by arbitrary amounts
+	in arbitrary directions when I try to move it for resizing the frames.
+	This patch makes it more quiet.
+
+Mon Jan 11 14:52:40 1999  Guido van Rossum  <guido@cnri.reston.va.us>
+
+	* TODO.txt: Some requests have been fulfilled.
+
+	* EditorWindow.py:
+	Set the cursor to a watch when opening the class browser (which may
+	take quite a while, browsing multiple files).
+
+	Newer, better center() -- but assumes no wrapping.
+
+	* SearchBinding.py:
+	Got rid of debug print statement in goto_line_event().
+
+	* ScriptBinding.py:
+	I think I like it better if it prints the traceback even when it displays
+	the stack viewer.
+
+	* Debugger.py: Bind ESC to close-window.
+
+	* ClassBrowser.py: Use a HSeparator between the classes and the items.
+	Make the list of classes wider by default (40 chars).
+	Bind ESC to close-window.
+
+	* Separator.py:
+	Separator classes (draggable divider between two panes).
+
+Sat Jan  9 22:01:33 1999  Guido van Rossum  <guido@cnri.reston.va.us>
+
+	* WindowList.py:
+	Don't traceback when wakeup() is called when the window has been destroyed.
+	This can happen when a torn-of Windows menu references closed windows.
+	And Tim Peters claims that the Windows menu is his favorite to tear off...
+
+	* EditorWindow.py: Allow tearing off of the Windows menu.
+
+	* StackViewer.py: Close on ESC.
+
+	* help.txt: Updated a bunch of things (it was mostly still 0.1!)
+
+	* extend.py: Added ScriptBinding to standard bindings.
+
+	* ScriptBinding.py:
+	This now actually works.  See doc string.  It can run a module (i.e.
+	import or reload) or debug it (same with debugger control).  Output
+	goes to a fresh output window, only created when needed.

+
+Thu Jan  7 00:12:15 1999  Guido van Rossum  <guido@cnri.reston.va.us>
+
+	* FormatParagraph.py:
+	Change paragraph width limit to 70 (like Emacs M-Q).
+
+	* README.txt:
+	Separating TODO from README.  Slight reformulation of features.  No
+	exact release date.
+
+	* TODO.txt: Separating TODO from README.
+
+Mon Jan  4 21:19:09 1999  Guido van Rossum  <guido@cnri.reston.va.us>
+
+	* FormatParagraph.py:
+	Hm.  There was a boundary condition error at the end of the file too.
+
+	* SearchBinding.py: Hm.  Add Unix binding for replace, too.
+
+	* keydefs.py: Ran eventparse.py again.
+
+	* FormatParagraph.py: Added Unix Meta-q key binding;
+	fix find_paragraph when at start of file.
+
+	* AutoExpand.py: Added Meta-/ binding for Unix as alt for Alt-/.
+
+	* SearchBinding.py:
+	Add unix binding for grep (otherwise the menu entry doesn't work!)
+
+	* ZoomHeight.py: Adjusted Unix height to work with fvwm96. :=(
+
+	* GrepDialog.py: Need to import sys!
+
+	* help.txt, extend.txt, README.txt: Formatted some paragraphs
+
+	* extend.py, FormatParagraph.py:
+	Add new extension to reformat a (text) paragraph.
+

+
+Sun Jan  3 00:47:35 1999  Guido van Rossum  <guido@cnri.reston.va.us>
+
+	* AutoIndent.py: Added something like Tim Peters' backspace patch.
+
+	* ZoomHeight.py: Adapted to Unix (i.e., more hardcoded constants).
+
+Sat Jan  2 21:28:54 1999  Guido van Rossum  <guido@cnri.reston.va.us>
+
+	* keydefs.py, idlever.py, idle.pyw, idle.bat, help.txt, extend.txt, extend.py, eventparse.py, ZoomHeight.py, WindowList.py, UndoDelegator.py, StackViewer.py, SearchEngine.py, SearchDialogBase.py, SearchDialog.py, ScrolledList.py, SearchBinding.py, ScriptBinding.py, ReplaceDialog.py, Attic/README, README.txt, PyShell.py, Attic/PopupMenu.py, OutputWindow.py, IOBinding.py, Attic/HelpWindow.py, History.py, GrepDialog.py, FileList.py, FrameViewer.py, EditorWindow.py, Debugger.py, Delegator.py, ColorDelegator.py, Bindings.py, ClassBrowser.py, AutoExpand.py, AutoIndent.py:
+	Checking in IDLE 0.2.
+
+	Much has changed -- too much, in fact, to write down.
+	The big news is that there's a standard way to write IDLE extensions;
+	see extend.txt.  Some sample extensions have been provided, and
+	some existing code has been converted to extensions.  Probably the
+	biggest new user feature is a new search dialog with more options,
+	search and replace, and even search in files (grep).
+
+	This is exactly as downloaded from my laptop after returning
+	from the holidays -- it hasn't even been tested on Unix yet.
+
+Fri Dec 18 15:52:54 1998  Guido van Rossum  <guido@cnri.reston.va.us>
+
+	* FileList.py, ClassBrowser.py:

+
+Tue Dec  8 20:39:36 1998  Guido van Rossum  <guido@cnri.reston.va.us>
+
+	* Attic/turtle.py: Moved to Python 1.5.2/Lib
+
+Fri Nov 27 03:19:20 1998  Guido van Rossum  <guido@cnri.reston.va.us>
+
+	* help.txt: Typo
+
+	* EditorWindow.py, FileList.py: Support underlining of menu labels
+
+	* Bindings.py:
+	New approach, separate tables for menus (platform-independent) and key
+	definitions (platform-specific), and generating accelerator strings
+	automatically from the key definitions.
+
+Mon Nov 16 18:37:42 1998  Guido van Rossum  <guido@cnri.reston.va.us>
+
+	* Attic/README: Clarify portability and main program.
+
+	* Attic/README: Added intro for 0.1 release and append Grail notes.
+
+Mon Oct 26 18:49:00 1998  Guido van Rossum  <guido@cnri.reston.va.us>

+	* Attic/turtle.py: root is now a global called _root
+
+Sat Oct 24 16:38:38 1998  Guido van Rossum  <guido@cnri.reston.va.us>
+
+	* Attic/turtle.py: Raise the root window on reset().
+	Different action on WM_DELETE_WINDOW is more likely to do the right thing,
+	allowing us to destroy old windows.
+
+	* Attic/turtle.py:
+	Split the goto() function in two: _goto() is the internal one,
+	using Canvas coordinates, and goto() uses turtle coordinates
+	and accepts variable argument lists.
+
+	* Attic/turtle.py: Cope with destruction of the window
+
+	* Attic/turtle.py: Turtle graphics
+
+	* Debugger.py: Use of Breakpoint class should be bdb.Breakpoint.
+
+Mon Oct 19 03:33:40 1998  Guido van Rossum  <guido@cnri.reston.va.us>
+
+	* SearchBinding.py:
+	Speed up the search a bit -- don't drag a mark around...
+
+	* PyShell.py:
+	Change our special entries from <console#N> to <pyshell#N>.
+	Patch linecache.checkcache() to keep our special entries alive.
+	Add popup menu to all editor windows to set a breakpoint.
+
+	* Debugger.py:
+	Use and pass through the 'force' flag to set_dict() where appropriate.
+	Default source and globals checkboxes to false.
+	Don't interact in user_return().
+	Add primitive set_breakpoint() method.
+
+	* ColorDelegator.py:
+	Raise priority of 'sel' tag so its foreground (on Windows) will take
+	priority over text colorization (which on Windows is almost the
+	same color as the selection background).
+
+	Define a tag and color for breakpoints ("BREAK").
+
+	* Attic/PopupMenu.py: Disable "Open stack viewer" and "help" commands.
+
+	* StackViewer.py:
+	Add optional 'force' argument (default 0) to load_dict().
+	If set, redo the display even if it's the same dict.
+
+Fri Oct 16 21:10:12 1998  Guido van Rossum  <guido@cnri.reston.va.us>
+
+	* StackViewer.py: Do nothing when loading the same dict as before.
+
+	* PyShell.py: Details for debugger interface.
+
+	* Debugger.py:
+	Restructured and more consistent.  Save checkboxes across instantiations.
+
+	* EditorWindow.py, Attic/README, Bindings.py:
+	Get rid of conflicting ^X binding.  Use ^W.
+
+	* Debugger.py, StackViewer.py:
+	Debugger can now show local and global variables.
+
+	* Debugger.py: Oops
+
+	* Debugger.py, PyShell.py: Better debugger support (show stack etc).
+
+	* Attic/PopupMenu.py: Follow renames in StackViewer module
+
+	* StackViewer.py:
+	Rename classes to StackViewer (the widget) and StackBrowser (the toplevel).
+
+	* ScrolledList.py: Add close() method
+
+	* EditorWindow.py: Clarify 'Open Module' dialog text
+
+	* StackViewer.py: Restructured into a browser and a widget.
+
+Thu Oct 15 23:27:08 1998  Guido van Rossum  <guido@cnri.reston.va.us>
+
+	* ClassBrowser.py, ScrolledList.py:
+	Generalized the scrolled list which is the base for the class and
+	method browser into a separate class in its own module.
+
+	* Attic/test.py: Cosmetic change
+
+	* Debugger.py: Don't show function name if there is none
+
+Wed Oct 14 03:43:05 1998  Guido van Rossum  <guido@cnri.reston.va.us>
+
+	* Debugger.py, PyShell.py: Polish the Debugger GUI a bit.
+	Closing it now also does the right thing.
+
+Tue Oct 13 23:51:13 1998  Guido van Rossum  <guido@cnri.reston.va.us>
+
+	* Debugger.py, PyShell.py, Bindings.py:
+	Ad primitive debugger interface (so far it will step and show you the
+	source, but it doesn't yet show the stack).
+
+	* Attic/README: Misc
+
+	* StackViewer.py: Whoops -- referenced self.top before it was set.
+
+	* help.txt: Added history and completion commands.
+
+	* help.txt: Updated
+
+	* FileList.py: Add class browser functionality.
+
+	* StackViewer.py:
+	Add a close() method and bind to WM_DELETE_WINDOW protocol
+
+	* PyShell.py: Clear the linecache before printing a traceback
+
+	* Bindings.py: Added class browser binding.
+
+	* ClassBrowser.py: Much improved, much left to do.
+
+	* PyShell.py: Make the return key do what I mean more often.
+
+	* ClassBrowser.py:
+	Adding the beginnings of a Class browser.  Incomplete, yet.
+
+	* EditorWindow.py, Bindings.py:
+	Add new command, "Open module".  You select or type a module name,
+	and it opens the source.
+
+Mon Oct 12 23:59:27 1998  Guido van Rossum  <guido@cnri.reston.va.us>
+
+	* PyShell.py: Subsume functionality from Popup menu in Debug menu.
+	Other stuff so the PyShell window can be resurrected from the Windows menu.
+
+	* FileList.py: Get rid of PopUp menu.
+	Create a simple Windows menu.  (Imperfect when Untitled windows exist.)
+	Add wakeup() method: deiconify, raise, focus.
+
+	* EditorWindow.py: Generalize menu creation.
+
+	* Bindings.py: Add Debug and Help menu items.
+
+	* EditorWindow.py: Added a menu bar to every window.
+
+	* Bindings.py: Add menu configuration to the event configuration.
+

+
+	* SearchBinding.py:
+	Add parent argument to 'go to line number' dialog box.
+
+Sat Oct 10 19:15:32 1998  Guido van Rossum  <guido@cnri.reston.va.us>
+
+	* StackViewer.py:
+	Add a label at the top showing (very basic) help for the stack viewer.
+	Add a label at the bottom showing the exception info.
+
+	* Attic/test.py, Attic/idle: Add Unix main script and test program.
+
+	* idle.pyw, help.txt, WidgetRedirector.py, UndoDelegator.py, StackViewer.py, SearchBinding.py, Attic/README, PyShell.py, Attic/PopupMenu.py, Percolator.py, Outline.py, IOBinding.py, History.py, Attic/HelpWindow.py, FrameViewer.py, FileList.py, EditorWindow.py, Delegator.py, ColorDelegator.py, Bindings.py, AutoIndent.py, AutoExpand.py:
+	Initial checking of Tk-based Python IDE.
+	Features: text editor with syntax coloring and undo;
+	subclassed into interactive Python shell which adds history.

+What's New in IDLE 3.10.z
+after 3.10.0 until 3.10.10?
+Released 2023-04-03?
+=========================
+
+
+gh-97527: Fix a bug in the previous bugfix that caused IDLE to not
+start when run with 3.10.8, 3.12.0a1, and at least Microsoft Python
+3.10.2288.0 installed without the Lib/test package.  3.11.0 was never
+affected.
+
+gh-65802: Document handling of extensions in Save As dialogs.
+
+gh-95191: Include prompts when saving Shell (interactive input/output).
+
+gh-95511: Fix the Shell context menu copy-with-prompts bug of copying
+an extra line when one selects whole lines.
+
+gh-95471: Tweak Edit menu. Move 'Select All' above 'Cut' as it is used
+with 'Cut' and 'Copy' but not 'Paste'.  Add a separator between 'Replace'
+and 'Go to Line' to help IDLE issue triagers.
+
+gh-95411: Enable using IDLE's module browser with .pyw files.
+
+gh-89610: Add .pyi as a recognized extension for IDLE on macOS.  This allows
+opening stub files by double clicking on them in the Finder.
+
+bpo-28950: Apply IDLE syntax highlighting to `.pyi` files.  Add util.py
+for common components.  Patch by Alex Waygood and Terry Jan Reedy.
+
+bpo-46630: Make query dialogs on Windows start with a cursor in the
+entry box.
+
+bpo-46591: Make the IDLE doc URL on the About IDLE dialog clickable.
+
+bpo-45296: Clarify close, quit, and exit in IDLE.  In the File menu,
+'Close' and 'Exit' are now 'Close Window' (the current one) and 'Exit'
+is now 'Exit IDLE' (by closing all windows).  In Shell, 'quit()' and
+'exit()' mean 'close Shell'.  If there are no other windows,
+this also exits IDLE.
+
+bpo-45495: Add context keywords 'case' and 'match' to completions list.
+
+bpo-45296: On Windows, change exit/quit message to suggest Ctrl-D, which
+works, instead of <Ctrl-Z Return>, which does not work in IDLE.
+
+
+What's New in IDLE 3.10.0
+(since 3.9.0)
+Released on 2021-10-04
+=========================
+
+bpo-45193: Make completion boxes appear on Ubuntu again.
+
+bpo-40128: Mostly fix completions on macOS when not using tcl/tk 8.6.11
+(as with 3.9).
+
+bpo-33962: Move the indent space setting from the Font tab to the new Windows
+tab. Patch by Mark Roseman and Terry Jan Reedy.
+
+bpo-40468: Split the settings dialog General tab into Windows and Shell/Ed
+tabs. Move help sources, which extend the Help menu, to the Extensions tab.
+Make space for new options and shorten the dialog. The latter makes the
+dialog better fit small screens.
+
+bpo-44010: Highlight the new match statement's soft keywords: match, case,
+and _. This highlighting is not perfect and will be incorrect in some rare
+cases, especially for some _s in case patterns.
+
+bpo-44026: Include interpreter's typo fix suggestions in message line
+for NameErrors and AttributeErrors.  Patch by E. Paine.
+
+bpo-41611: Avoid occasional uncaught exceptions and freezing when using
+completions on macOS.
+
+bpo-37903: Add mouse actions to the shell sidebar.  Left click and
+optional drag selects one or more lines of text, as with the
+editor line number sidebar.  Right click after selecting text lines
+displays a context menu with 'copy with prompts'.  This zips together
+prompts from the sidebar with lines from the selected text.  This option
+also appears on the context menu for the text.
+
+bpo-43981: Fix reference leaks in test_sidebar and test_squeezer.
+Patches by Terry Jan Reedy and Pablo Galindo

+masquerade rules or failure displaying complex colored (non-ascii) characters.
+
+bpo-43283: Document why printing to IDLE's Shell is often slower than
+printing to a system terminal and that it can be made faster by
+pre-formatting a single string before printing.
+
+bpo-23544: Disable Debug=>Stack Viewer when user code is running or
+Debugger is active, to prevent hang or crash.  Patch by Zackery Spytz.
+

+
+bpo-42416: Display docstrings in IDLE calltips in more cases,
+by using inspect.getdoc.
+
+bpo-33987: Mostly finish using ttk widgets, mainly for editor,
+settings, and searches.  Some patches by Mark Roseman.
+
+bpo-40511: Stop unnecessary "flashing" when typing opening and closing
+parentheses inside the parentheses of a function call.
+
+bpo-38439: Add a 256x256 pixel IDLE icon to the Windows .ico file. Created by

+
+What's New in IDLE 3.9.0 (since 3.8.0)
+Released on 2020-10-05?
+======================================
+
+bpo-41468: Improve IDLE run crash error message (which users should
+never see).
+
+bpo-41373: Save files loaded with no line ending, as when blank, or
+different line endings, by setting its line ending to the system
+default. Fix regression in 3.8.4 and 3.9.0b4.
+
+bpo-41300: Save files with non-ascii chars.  Fix regression in
+3.9.0b4 and 3.8.4.
+
+bpo-37765: Add keywords to module name completion list.  Rewrite
+Completions section of IDLE doc.
+
+bpo-41152: The encoding of ``stdin``, ``stdout`` and ``stderr`` in IDLE
+is now always UTF-8.
+
+bpo-41144: Make Open Module open a special module such as os.path.
+
+bpo-40723: Make test_idle pass when run after import.
+Patch by Florian Dahlitz.
+
+bpo-38689: IDLE will no longer freeze when inspect.signature fails
+when fetching a calltip.
+
+bpo-27115: For 'Go to Line', use a Query entry box subclass with
+IDLE standard behavior and improved error checking.
+
+bpo-39885: When a context menu is invoked by right-clicking outside
+of a selection, clear the selection and move the cursor.  Cut and
+Copy require that the click be within the selection.
+
+bpo-39852: Edit "Go to line" now clears any selection, preventing
+accidental deletion.  It also updates Ln and Col on the status bar.
+
+bpo-39781: Selecting code context lines no longer causes a jump.
+
+bpo-39663: Add tests for pyparse find_good_parse_start().
+
+bpo-39600: Remove duplicate font names from configuration list.
+
+bpo-38792: Close a shell calltip if a :exc:`KeyboardInterrupt`

+functions (default shortcuts Alt-T and Alt-U) were mistakenly disabled
+in 3.7.5 and 3.8.0.
+
+bpo-4630: Add an option to toggle IDLE's cursor blink for shell,
+editor, and output windows.  See Settings, General, Window Preferences,
+Cursor Blink.  Patch by Zackery Spytz.
+
+bpo-26353: Stop adding newline when saving an IDLE shell window.
+
+bpo-38598: Do not try to compile IDLE shell or output windows.
+
+
+What's New in IDLE 3.8.0 (since 3.7.0)
+Released on 2019-10-14
+======================================
+
+bpo-36698: IDLE no longer fails when writing non-encodable characters
+to stderr.  It now escapes them with a backslash, like the regular
+Python interpreter.  Add an errors field to the standard streams.
+
+bpo-13153: Improve tkinter's handing of non-BMP (astral) unicode
+characters, such as 'rocket \U0001f680'.  Whether a proper glyph or
+replacement char is displayed depends on the OS and font.  For IDLE,
+astral chars in code interfere with editing.
+
+bpo-35379: When exiting IDLE, catch any AttributeError.  One happens
+when EditorWindow.close is called twice.  Printing a traceback, when
+IDLE is run from a terminal, is useless and annoying.
+
+bpo-38183: To avoid test issues, test_idle ignores the user config
+directory.  It no longer tries to create or access .idlerc or any files
+within.  Users must run IDLE to discover problems with saving settings.
+
+bpo-38077: IDLE no longer adds 'argv' to the user namespace when
+initializing it.  This bug only affected 3.7.4 and 3.8.0b2 to 3.8.0b4.
+
+bpo-38401: Shell restart lines now fill the window width, always start
+with '=', and avoid wrapping unnecessarily. The line will still wrap
+if the included file name is long relative to the width.
+
+bpo-37092: Add mousewheel scrolling for IDLE module, path, and stack
+browsers.  Patch by George Zhang.
+
+bpo-35771: To avoid occasional spurious test_idle failures on slower
+machines, increase the ``hover_delay`` in test_tooltip.
+
+bpo-37824: Properly handle user input warnings in IDLE shell.
+Cease turning SyntaxWarnings into SyntaxErrors.
+
+bpo-37929: IDLE Settings dialog now closes properly when there is no
+shell window.
+
+bpo-37849: Fix completions list appearing too high or low when shown
+above the current line.
+
+bpo-36419: Refactor autocompete and improve testing.
+
+bpo-37748: Reorder the Run menu.  Put the most common choice,
+Run Module, at the top.
+
+bpo-37692: Improve highlight config sample with example shell
+interaction and better labels for shell elements.
+
+bpo-37628: Settings dialog no longer expands with font size.
+The font and highlight sample boxes gain scrollbars instead.
+
+bpo-17535: Add optional line numbers for IDLE editor windows.
+
+bpo-37627: Initialize the Customize Run dialog with the command line
+arguments most recently entered before.  The user can optionally edit
+before submitting them.
+
+bpo-33610: Code context always shows the correct context when toggled on.
+
+bpo-36390: Gather Format menu functions into format.py.  Combine
+paragraph.py, rstrip.py, and format methods from editor.py.
+
+bpo-37530: Optimize code context to reduce unneeded background activity.
+Font and highlight changes now occur along with text changes instead
+of after a random delay.
+
+bpo-27452: Cleanup config.py by inlining RemoveFile and simplifying
+the handling of __file__ in CreateConfigHandlers/
+
+bpo-26806: To compensate for stack frames added by IDLE and avoid
+possible problems with low recursion limits, add 30 to limits in the
+user code execution process.  Subtract 30 when reporting recursion
+limits to make this addition mostly transparent.
+
+bpo-37325: Fix tab focus traversal order for help source and custom
+run dialogs.
+
+bpo-37321: Both subprocess connection error messages now refer to
+the 'Startup failure' section of the IDLE doc.
+
+bpo-37177: Properly attach search dialogs to their main window so
+that they behave like other dialogs and do not get hidden behind
+their main window.
+
+bpo-37039: Adjust "Zoom Height" to individual screens by momentarily
+maximizing the window on first use with a particular screen.  Changing
+screen settings may invalidate the saved height.  While a window is
+maximized, "Zoom Height" has no effect.
+
+bpo-35763: Make calltip reminder about '/' meaning positional-only less
+obtrusive by only adding it when there is room on the first line.
+
+bpo-5680: Add 'Run Customized' to the Run menu to run a module with
+customized settings. Any command line arguments entered are added
+to sys.argv. One can suppress the normal Shell main module restart.
+
+bpo-35610: Replace now redundant editor.context_use_ps1 with
+.prompt_last_line.  This finishes change started in bpo-31858.
+
+bpo-32411: Stop sorting dict created with desired line order.
+
+bpo-37038: Make idlelib.run runnable; add test clause.
+
+bpo-36958: Print any argument other than None or int passed to
+SystemExit or sys.exit().
+
+bpo-36807: When saving a file, call file.flush() and os.fsync()
+so bits are flushed to e.g. a USB drive.
+
+bpo-36429: Fix starting IDLE with pyshell.
+Add idlelib.pyshell alias at top; remove pyshell alias at bottom.
+Remove obsolete __name__=='__main__' command.
+
+bpo-30348: Increase test coverage of idlelib.autocomplete by 30%.
+Patch by Louie Lu.
+
+bpo-23205: Add tests and refactor grep's findfiles.
+
+bpo-36405: Use dict unpacking in idlelib.
+
+bpo-36396: Remove fgBg param of idlelib.config.GetHighlight().
+This param was only used twice and changed the return type.
+
+bpo-23216: IDLE: Add docstrings to search modules.
+
+bpo-36176: Fix IDLE autocomplete & calltip popup colors.
+Prevent conflicts with Linux dark themes
+(and slightly darken calltip background).
+
+bpo-36152: Remove colorizer.ColorDelegator.close_when_done and the
+corresponding argument of .close().  In IDLE, both have always been
+None or False since 2007.
+
+bpo-36096: Make colorizer state variables instance-only.
+
+bpo-32129: Avoid blurry IDLE application icon on macOS with Tk 8.6.
+Patch by Kevin Walzer.
+
+bpo-24310: Document settings dialog font tab sample.
+
+bpo-35689: Add docstrings and tests for colorizer.
+
+bpo-35833: Revise IDLE doc for control codes sent to Shell.
+Add a code example block.
+
+bpo-35770: IDLE macosx deletes Options => Configure IDLE.
+It previously deleted Window => Zoom Height by mistake.
+(Zoom Height is now on the Options menu).  On Mac, the settings
+dialog is accessed via Preferences on the IDLE menu.
+
+bpo-35769: Change new file name from 'Untitled' to 'untitled'.
+
+bpo-35660: Fix imports in window module.
+
+bpo-35641: Properly format calltip for function without docstring.
+
+bpo-33987: Use ttk Frame for ttk widgets.
+
+bpo-34055: Fix erroneous 'smart' indents and newlines in IDLE Shell.
+
+bpo-28097: Add Previous/Next History entries to Shell menu.
+
+bpo-35591: Find Selection now works when selection not found.
+
+bpo-35598: Update config_key: use PEP 8 names and ttk widgets,
+make some objects global, and add tests.
+
+bpo-35196: Speed up squeezer line counting.
+
+bpo-35208: Squeezer now counts wrapped lines before newlines.
+
+bpo-35555: Gray out Code Context menu entry when it's not applicable.
+
+bpo-22703: Improve the Code Context and Zoom Height menu labels.
+The Code Context menu label now toggles between Show/Hide Code Context.
+The Zoom Height menu now toggles between Zoom/Restore Height.
+Zoom Height has moved from the Window menu to the Options menu.
+
+bpo-35521: Document the editor code context feature.
+Add some internal references within the IDLE doc.
+
+bpo-34864: When starting IDLE on MacOS, warn if the system setting
+"Prefer tabs when opening documents" is "Always".  As previous
+documented for this issue, running IDLE with this setting causes
+problems.  If the setting is changed while IDLE is running,
+there will be no warning until IDLE is restarted.
+
+bpo-35213: Where appropriate, use 'macOS' in idlelib.
+
+bpo-34864: Document two IDLE on MacOS issues.  The System Preferences
+Dock "prefer tabs always" setting disables some IDLE features.
+Menus are a bit different than as described for Windows and Linux.
+
+bpo-35202: Remove unused imports in idlelib.
+
+bpo-33000: Document that IDLE's shell has no line limit.
+A program that runs indefinitely can overfill memory.
+
+bpo-23220: Explain how IDLE's Shell displays output.
+Add new subsection "User output in Shell".
+
+bpo-35099: Improve the doc about IDLE running user code.
+"IDLE -- console differences" is renamed "Running user code".
+It mostly covers the implications of using custom sys.stdxxx objects.
+
+bpo-35097: Add IDLE doc subsection explaining editor windows.
+Topics include opening, title and status bars, .py* extension, and running.
+
+Issue 35093: Document the IDLE document viewer in the IDLE doc.
+Add a paragraph in "Help and preferences", "Help sources" subsection.
+
+bpo-1529353: Explain Shell text squeezing in the IDLE doc.
+
+bpo-35088: Update idlelib.help.copy_string docstring.
+We now use git and backporting instead of hg and forward merging.
+
+bpo-35087: Update idlelib help files for the current doc build.
+The main change is the elimination of chapter-section numbers.
+
+bpo-1529353: Output over N lines (50 by default) is squeezed down to a button.
+N can be changed in the PyShell section of the General page of the
+Settings dialog.  Fewer, but possibly extra long, lines can be squeezed by
+right clicking on the output.  Squeezed output can be expanded in place
+by double-clicking the button or into the clipboard or a separate window
+by right-clicking the button.
+
+bpo-34548: Use configured color theme for read-only text views.
+
+bpo-33839: Refactor ToolTip and CallTip classes; add documentation
+and tests.
+
+bpo-34047: Fix mouse wheel scrolling direction on macOS.
+
+bpo-34275: Make calltips always visible on Mac.
+Patch by Kevin Walzer.
+
+bpo-34120: Fix freezing after closing some dialogs on Mac.
+This is one of multiple regressions from using newer tcl/tk.
+
+bpo-33975: Avoid small type when running htests.
+Since part of the purpose of human-viewed tests is to determine that
+widgets look right, it is important that they look the same for
+testing as when running IDLE.
+
+bpo-33905: Add test for idlelib.stackview.StackBrowser.
+
+bpo-33924: Change mainmenu.menudefs key 'windows' to 'window'.
+Every other menudef key is the lowercase version of the
+corresponding main menu entry (in this case, 'Window').
+
+bpo-33906: Rename idlelib.windows as window
+Match Window on the main menu and remove last plural module name.
+Change imports, test, and attribute references to match new name.
+
+bpo-33917: Fix and document idlelib/idle_test/template.py.
+The revised file compiles, runs, and tests OK.  idle_test/README.txt
+explains how to use it to create new IDLE test files.
+
+bpo-33904: In rstrip module, rename class RstripExtension as Rstrip.
+
+bpo-33907: For consistency and clarity, rename calltip objects.
+Module calltips and its class CallTips are now calltip and Calltip.
+In module calltip_w, class CallTip is now CalltipWindow.
+
+bpo-33855: Minimally test all IDLE modules.
+Standardize the test file format.  Add missing test files that import
+the tested module and perform at least one test.  Check and record the
+coverage of each test.
+
+bpo-33856: Add 'help' to Shell's initial welcome message.
+
+
+What's New in IDLE 3.7.0 (since 3.6.0)
+Released on 2018-06-27
+======================================
+
+bpo-33656: On Windows, add API call saying that tk scales for DPI.
+On Windows 8.1+ or 10, with DPI compatibility properties of the Python
+binary unchanged, and a monitor resolution greater than 96 DPI, this
+should make text and lines sharper and some colors brighter.
+On other systems, it should have no effect.  If you have a custom theme,
+you may want to adjust a color or two.  If perchance it make text worse
+on your monitor, you can disable the ctypes.OleDLL call near the top of
+pyshell.py and report the problem on python-list or idle-dev@python.org.
+
+bpo-33768: Clicking on a context line moves that line to the top
+of the editor window.
+
+bpo-33763: Replace the code context label widget with a text widget.
+
+bpo-33664: Scroll IDLE editor text by lines.
+(Previously, the mouse wheel and scrollbar slider moved text by a fixed
+number of pixels, resulting in partial lines at the top of the editor
+box.)  This change also applies to the shell and grep output windows,
+but currently not to read-only text views.
+
+bpo-33679: Enable theme-specific color configuration for Code Context.
+(Previously, there was one code context foreground and background font
+color setting, default or custom, on the extensions tab, that applied
+to all themes.)  For built-in themes, the foreground is the same as
+normal text and the background is a contrasting gray.  Context colors for
+custom themes are set on the Hightlights tab along with other colors.
+When one starts IDLE from a console and loads a custom theme without
+definitions for 'context', one will see a warning message on the
+console.
+
+bpo-33642: Display up to maxlines non-blank lines for Code Context.
+If there is no current context, show a single blank line.  (Previously,
+the Code Contex had numlines lines, usually with some blank.)  The use
+of a new option, 'maxlines' (default 15), avoids possible interference
+with user settings of the old option, 'numlines' (default 3).
+
+bpo-33628: Cleanup codecontext.py and its test.
+
+bpo-32831: Add docstrings and tests for codecontext.py.
+Coverage is 100%.  Patch by Cheryl Sabella.
+
+bpo-33564: Code context now recognizes async as a block opener.
+
+bpo-21474: Update word/identifier definition from ascii to unicode.
+In text and entry boxes, this affects selection by double-click,
+movement left/right by control-left/right, and deletion left/right
+by control-BACKSPACE/DEL.
+
+bpo-33204: Consistently color invalid string prefixes.
+A 'u' string prefix cannot be paired with either 'r' or 'f'.
+IDLE now consistently colors as much of the prefix, starting at the
+right, as is valid.  Revise and extend colorizer test.
+
+bpo-32984: Set __file__ while running a startup file.
+Like Python, IDLE optionally runs 1 startup file in the Shell window
+before presenting the first interactive input prompt.  For IDLE,
+option -s runs a file named in environmental variable IDLESTARTUP or
+PYTHONSTARTUP; -r file runs file.  Python sets __file__ to the startup
+file name before running the file and unsets it before the first
+prompt.  IDLE now does the same when run normally, without the -n
+option.
+
+bpo-32940: Replace StringTranslatePseudoMapping with faster code.
+
+bpo-32916: Change 'str' to 'code' in idlelib.pyparse and users.
+
+bpo-32905: Remove unused code in pyparse module.
+
+bpo-32874: IDLE - add pyparse tests with 97% coverage.
+
+bpo-32837: IDLE - require encoding argument for textview.view_file.
+Using the system and place-dependent default encoding for open()
+is a bad idea for IDLE's system and location-independent files.
+
+bpo-32826: Add "encoding=utf-8" to open() in IDLE's test_help_about.
+GUI test test_file_buttons() only looks at initial ascii-only lines,
+but failed on systems where open() defaults to 'ascii' because
+readline() internally reads and decodes far enough ahead to encounter
+a non-ascii character in CREDITS.txt.
+
+bpo-32765: Update configdialog General tab create page docstring.
+Add new widgets to the widget list.
+
+bpo-32207: Improve tk event exception tracebacks in IDLE.
+When tk event handling is driven by IDLE's run loop, a confusing
+and distracting queue.EMPTY traceback context is no longer added
+to tk event exception tracebacks.  The traceback is now the same
+as when event handling is driven by user code.  Patch based on
+a suggestion by Serhiy Storchaka.
+
+bpo-32164: Delete unused file idlelib/tabbedpages.py.
+Use of TabbedPageSet in configdialog was replaced by ttk.Notebook.
+
+bpo-32100: Fix old and new bugs in pathbrowser; improve tests.
+Patch mostly by Cheryl Sabella.
+
+bpo-31860: The font sample in the settings dialog is now editable.
+Edits persist while IDLE remains open.
+Patch by Serhiy Storchake and Terry Jan Reedy.
+
+bpo-31858: Restrict shell prompt manipulation to the shell.
+Editor and output windows only see an empty last prompt line.  This
+simplifies the code and fixes a minor bug when newline is inserted.
+Sys.ps1, if present, is read on Shell start-up, but is not set or changed.
+Patch by Terry Jan Reedy.
+
+bpo-28603: Fix a TypeError that caused a shell restart when printing
+a traceback that includes an exception that is unhashable.
+Patch by Zane Bitter.
+
+bpo-13802: Use non-Latin characters in the Font settings sample.
+Even if one selects a font that defines a limited subset of the unicode
+Basic Multilingual Plane, tcl/tk will use other fonts that define a
+character.  The expanded example give users of non-Latin characters
+a better idea of what they might see in the shell and editors.
+
+To make room for the expanded sample, frames on the Font tab are
+re-arranged.  The Font/Tabs help explains a bit about the additions.
+Patch by Terry Jan Reedy
+
+bpo-31460: Simplify the API of IDLE's Module Browser.
+Passing a widget instead of an flist with a root widget opens the
+option of creating a browser frame that is only part of a window.
+Passing a full file name instead of pieces assumed to come from a
+.py file opens the possibility of browsing python files that do not
+end in .py.
+
+bpo-31649: Make _htest and _utest parameters keyword-only.
+These are used to adjust code for human and unit tests.
+
+bpo-31459: Rename module browser from Class Browser to Module Browser.
+The original module-level class and method browser became a module
+browser, with the addition of module-level functions, years ago.
+Nested classes and functions were added yesterday.  For back-
+compatibility, the virtual event <<open-class-browser>>, which
+appears on the Keys tab of the Settings dialog, is not changed.
+Patch by Cheryl Sabella.
+
+bpo-1612262: Module browser now shows nested classes and functions.
+Original patches for code and tests by Guilherme Polo and
+Cheryl Sabella, respectively.  Revisions by Terry Jan Reedy.
+
+bpo-31500: Tk's default fonts now are scaled on HiDPI displays.
+This affects all dialogs.  Patch by Serhiy Storchaka.
+
+bpo-31493: Fix code context update and font update timers.
+Canceling timers prevents a warning message when test_idle completes.
+
+bpo-31488: Update non-key options in former extension classes.
+When applying configdialog changes, call .reload for each feature class.
+Change ParenMatch so updated options affect existing instances attached
+to existing editor windows.
+
+bpo-31477: Improve rstrip entry in IDLE doc.
+Strip Trailing Whitespace strips more than blank spaces.
+Multiline string literals are not skipped.
+
+bpo-31480: fix tests to pass with zzdummy extension disabled. (#3590)
+To see the example in action, enable it on options extensions tab.
+
+bpo-31421: Document how IDLE runs tkinter programs.
+IDLE calls tcl/tk update in the background in order to make live
+interaction and experimentation with tkinter applications much easier.
+
+bpo-31414: Fix tk entry box tests by deleting first.
+Adding to an int entry is not the same as deleting and inserting
+because int('') will fail.  Patch by Terry Jan Reedy.
+
+bpo-27099: Convert IDLE's built-in 'extensions' to regular features.
+  About 10 IDLE features were implemented as supposedly optional
+extensions.  Their different behavior could be confusing or worse for
+users and not good for maintenance.  Hence the conversion.
+  The main difference for users is that user configurable key bindings
+for builtin features are now handled uniformly.  Now, editing a binding
+in a keyset only affects its value in the keyset.  All bindings are
+defined together in the system-specific default keysets in config-
+extensions.def.  All custom keysets are saved as a whole in config-
+extension.cfg.  All take effect as soon as one clicks Apply or Ok.
+   The affected events are '<<force-open-completions>>',
+'<<expand-word>>', '<<force-open-calltip>>', '<<flash-paren>>',
+'<<format-paragraph>>', '<<run-module>>', '<<check-module>>', and

+  Initial patch by Charles Wohlganger, revised by Terry Jan Reedy.

+Patch by Cheryl Sabella.
+
+bpo-19903: Change calltipes to use inspect.signature.
+Idlelib.calltips.get_argspec now uses inspect.signature instead of
+inspect.getfullargspec, like help() does.  This improves the signature
+in the call tip in a few different cases, including builtins converted
+to provide a signature.  A message is added if the object is not
+callable, has an invalid signature, or if it has positional-only
+parameters.  Patch by Louie Lu.

+
+bpo-30853: IDLE -- Factor a VarTrace class out of ConfigDialog.
+Instance tracers manages pairs consisting of a tk variable and a
+callback function.  When tracing is turned on, setting the variable

+Patch by Terry Jan Reedy.
+
+bpo-31003: IDLE: Add more tests for General tab.
+Patch by Terry Jan Reedy.
+
+bpo-30993: IDLE - Improve configdialog font page and tests.

+docstring.  Simplify some attribute names. Move set_samples calls to
+var_changed_font (idea from Cheryl Sabella).  Move related functions to
+positions after the create widgets function.
+* In test_configdialog: Fix test_font_set so not order dependent.  Fix
+renamed test_indent_scale so it tests the widget.  Adjust tests for
+movement of set_samples call.  Add tests for load functions.  Put all
+font tests in one class and tab indent tests in another.  Except for
+two lines, these tests completely cover the related functions.

+
+- Issue #24455: Prevent IDLE from hanging when a) closing the shell while the
+  debugger is active (15347); b) closing the debugger with the [X] button
+  (15348); and c) activating the debugger when already active (24455).
+  The patch by Mark Roseman does this by making two changes.

+  Strings, comments, keywords, ... are still green, red, orange, ... .
+  To use it with IDLEs released before November 2015, hit the
+  'Save as New Custom Theme' button and enter a new name,
+  such as 'Custom Dark'.  The custom theme will work with any IDLE
+  release, and can be modified.
+
+- Issue #25224: README.txt is now an idlelib index for IDLE developers and
+  curious users.  The previous user content is now in the IDLE doc chapter.

+  at the top of the screen.

+Original IDLE todo, much of it now outdated:
+============================================
+TO DO:
+
+- improve debugger:
+    - manage breakpoints globally, allow bp deletion, tbreak, cbreak etc.
+    - real object browser
+    - help on how to use it (a simple help button will do wonders)
+    - performance?  (updates of large sets of locals are slow)
+    - better integration of "debug module"
+    - debugger should be global resource (attached to flist, not to shell)
+    - fix the stupid bug where you need to step twice
+    - display class name in stack viewer entries for methods
+    - suppress tracing through IDLE internals (e.g. print) DONE
+    - add a button to suppress through a specific module or class or method
+    - more object inspection to stack viewer, e.g. to view all array items
+- insert the initial current directory into sys.path DONE
+- default directory attribute for each window instead of only for windows
+  that have an associated filename
+- command expansion from keywords, module contents, other buffers, etc.
+- "Recent documents" menu item DONE
+- Filter region command
+- Optional horizontal scroll bar
+- more Emacsisms:
+    - ^K should cut to buffer
+    - M-[, M-] to move by paragraphs
+    - incremental search?
+- search should indicate wrap-around in some way
+- restructure state sensitive code to avoid testing flags all the time
+- persistent user state (e.g. window and cursor positions, bindings)
+- make backups when saving
+- check file mtimes at various points
+- Pluggable interface with RCS/CVS/Perforce/Clearcase
+- better help?
+- don't open second class browser on same module (nor second path browser)
+- unify class and path browsers
+- Need to define a standard way whereby one can determine one is running
+  inside IDLE (needed for Tk mainloop, also handy for $PYTHONSTARTUP)
+- Add more utility methods for use by extensions (a la get_selection)
+- Way to run command in totally separate interpreter (fork+os.system?) DONE
+- Way to find definition of fully-qualified name:
+  In other words, select "UserDict.UserDict", hit some magic key and
+  it loads up UserDict.py and finds the first def or class for UserDict.
+- need a way to force colorization on/off
+- need a way to force auto-indent on/off
+
+Details:
+
+- ^O (on Unix -- open-line) should honor autoindent
+- after paste, show end of pasted text
+- on Windows, should turn short filename to long filename (not only in argv!)
+  (shouldn't this be done -- or undone -- by ntpath.normpath?)
+- new autoindent after colon even indents when the colon is in a comment!
+- sometimes forward slashes in pathname remain
+- sometimes star in window name remains in Windows menu
+- With unix bindings, ESC by itself is ignored
+- Sometimes for no apparent reason a selection from the cursor to the
+  end of the command buffer appears, which is hard to get rid of
+  because it stays when you are typing!
+- The Line/Col in the status bar can be wrong initially in PyShell DONE
+
+Structural problems:
+
+- too much knowledge in FileList about EditorWindow (for example)
+- should add some primitives for accessing the selection etc.
+  to repeat cumbersome code over and over
+
+======================================================================
+
+Jeff Bauer suggests:
+
+- Open Module doesn't appear to handle hierarchical packages.
+- Class browser should also allow hierarchical packages.
+- Open and Open Module could benefit from a history, DONE
+  either command line style, or Microsoft recent-file
+  style.
+- Add a Smalltalk-style inspector  (i.e. Tkinspect)
+
+The last suggestion is already a reality, but not yet
+integrated into IDLE.  I use a module called inspector.py,
+that used to be available from python.org(?)  It no longer
+appears to be in the contributed section, and the source
+has no author attribution.
+
+In any case, the code is useful for visually navigating
+an object's attributes, including its container hierarchy.
+
+    >>> from inspector import Tkinspect
+    >>> Tkinspect(None, myObject)
+
+Tkinspect could probably be extended and refined to
+integrate better into IDLE.
+
+======================================================================
+
+Comparison to PTUI
+------------------
+
++ PTUI's help is better (HTML!)
+
++ PTUI can attach a shell to any module
+
++ PTUI has some more I/O commands:
+  open multiple
+  append
+  examine (what's that?)
+
+======================================================================
+
+Notes after trying to run Grail
+-------------------------------
+
+- Grail does stuff to sys.path based on sys.argv[0]; you must set
+sys.argv[0] to something decent first (it is normally set to the path of
+the idle script).
+
+- Grail must be exec'ed in __main__ because that's imported by some
+other parts of Grail.
+
+- Grail uses a module called History and so does idle :-(
+
+======================================================================
+
+Robin Friedrich's items:
+
+Things I'd like to see:
+    - I'd like support for shift-click extending the selection. There's a
+      bug now that it doesn't work the first time you try it.
+    - Printing is needed. How hard can that be on Windows? FIRST CUT DONE
+    - The python-mode trick of autoindenting a line with <tab> is neat and
+      very handy.
+    - (someday) a spellchecker for docstrings and comments.
+    - a pagedown/up command key which moves to next class/def statement (top
+      level)
+    - split window capability
+    - DnD text relocation/copying
+
+Things I don't want to see.
+    - line numbers...  will probably slow things down way too much.
+    - Please use another icon for the tree browser leaf. The small snake
+      isn't cutting it.
+
+----------------------------------------------------------------------
+
+- Customizable views (multi-window or multi-pane).  (Markus Gritsch)
+
+- Being able to double click (maybe double right click) on a callable
+object in the editor which shows the source of the object, if
+possible.  (Gerrit Holl)
+
+- Hooks into the guts, like in Emacs.  (Mike Romberg)
+
+- Sharing the editor with a remote tutor.  (Martijn Faassen)
+
+- Multiple views on the same file.  (Tony J Ibbs)
+
+- Store breakpoints in a global (per-project) database (GvR); Dirk
+Heise adds: save some space-trimmed context and search around when
+reopening a file that might have been edited by someone else.
+
+- Capture menu events in extensions without changing the IDLE source.
+(Matthias Barmeier)
+
+- Use overlapping panels (a "notebook" in MFC terms I think) for info
+that doesn't need to be accessible simultaneously (e.g. HTML source
+and output).  Use multi-pane windows for info that does need to be
+shown together (e.g. class browser and source).  (Albert Brandl)
+
+- A project should invisibly track all symbols, for instant search,
+replace and cross-ref.  Projects should be allowed to span multiple
+directories, hosts, etc.  Project management files are placed in a
+directory you specify.  A global mapping between project names and
+project directories should exist [not so sure --GvR].  (Tim Peters)
+
+- Merge attr-tips and auto-expand.  (Mark Hammond, Tim Peters)
+
+- Python Shell should behave more like a "shell window" as users know
+it -- i.e. you can only edit the current command, and the cursor can't
+escape from the command area.  (Albert Brandl)
+
+- Set X11 class to "idle/Idle", set icon and title to something
+beginning with "idle" -- for window manangers.  (Randall Hopper)
+
+- Config files editable through a preferences dialog.  (me) DONE
+
+- Config files still editable outside the preferences dialog.
+(Randall Hopper) DONE
+
+- When you're editing a command in PyShell, and there are only blank
+lines below the cursor, hitting Return should ignore or delete those
+blank lines rather than deciding you're not on the last line.  (me)
+
+- Run command (F5 c.s.) should be more like Pythonwin's Run -- a
+dialog with options to give command line arguments, run the debugger,
+etc.  (me)
+
+- Shouldn't be able to delete part of the prompt (or any text before
+it) in the PyShell.  (Martijn Faassen)   DONE
+
+- Emacs style auto-fill (also smart about comments and strings).
+(Jeremy Hylton)
+
+- Output of Run Script should go to a separate output window, not to
+the shell window.  Output of separate runs should all go to the same
+window but clearly delimited.  (David Scherer) REJECT FIRST, LATTER DONE
+
+- GUI form designer to kick VB's butt.  (Robert Geiger) THAT'S NOT IDLE
+
+- Printing!  Possibly via generation of PDF files which the user must
+then send to the printer separately.  (Dinu Gherman)  FIRST CUT

+Once code has scrolled off the top of a window, it can be difficult to
+determine which block you are in.  This extension implements a pane at the top
+of each IDLE edit window which provides block structure hints.  These hints are
+the lines which contain the block opening keywords, e.g. 'if', for the
+enclosing block.  The number of hint lines is determined by the maxlines
+variable in the codecontext section of config-extensions.def. Lines which do
+not open blocks are not shown in the context hints pane.

+"""idlelib.config -- Manage IDLE configuration information.
+
+The comments at the beginning of config-main.def describe the
+configuration files and the design implemented to update user
+configuration information.  In particular, user configuration choices
+which duplicate the defaults will be removed from the user's
+configuration files, and if a user file becomes empty, it will be
+deleted.
+
+The configuration database maps options to values.  Conceptually, the
+database keys are tuples (config-type, section, item).  As implemented,
+there are  separate dicts for default and user values.  Each has
+config-type keys 'main', 'extensions', 'highlight', and 'keys'.  The
+value for each key is a ConfigParser instance that maps section and item
+to values.  For 'main' and 'extensions', user values override
+default values.  For 'highlight' and 'keys', user sections augment the
+default sections (and must, therefore, have distinct names).
+
+Throughout this module there is an emphasis on returning useable defaults
+when a problem occurs in returning a requested configuration value back to
+idle. This is to allow IDLE to continue to function in spite of errors in
+the retrieval of config information. When a default is returned instead of
+a requested config value, a message is printed to stderr to aid in
+configuration problem notification and resolution.

+Writing an IDLE extension
+=========================
+
+An IDLE extension can define new key bindings and menu entries for IDLE
+edit windows.  There is a simple mechanism to load extensions when IDLE
+starts up and to attach them to each edit window. (It is also possible
+to make other changes to IDLE, but this must be done by editing the IDLE
+source code.)
+
+The list of extensions loaded at startup time is configured by editing
+the file config-extensions.def.  See below for details.
+
+An IDLE extension is defined by a class.  Methods of the class define
+actions that are invoked by event bindings or menu entries. Class (or
+instance) variables define the bindings and menu additions; these are
+automatically applied by IDLE when the extension is linked to an edit
+window.
+
+An IDLE extension class is instantiated with a single argument,
+`editwin', an EditorWindow instance. The extension cannot assume much
+about this argument, but it is guaranteed to have the following instance
+variables:
+
+    text	a Text instance (a widget)
+    io		an IOBinding instance (more about this later)
+    flist	the FileList instance (shared by all edit windows)
+
+(There are a few more, but they are rarely useful.)
+
+The extension class must not directly bind Window Manager (e.g. X) events.
+Rather, it must define one or more virtual events, e.g. <<z-in>>, and
+corresponding methods, e.g. z_in_event().  The virtual events will be
+bound to the corresponding methods, and Window Manager events can then be bound
+to the virtual events. (This indirection is done so that the key bindings can
+easily be changed, and so that other sources of virtual events can exist, such
+as menu entries.)
+
+An extension can define menu entries.  This is done with a class or instance
+variable named menudefs; it should be a list of pairs, where each pair is a
+menu name (lowercase) and a list of menu entries. Each menu entry is either
+None (to insert a separator entry) or a pair of strings (menu_label,
+virtual_event).  Here, menu_label is the label of the menu entry, and
+virtual_event is the virtual event to be generated when the entry is selected.
+An underscore in the menu label is removed; the character following the
+underscore is displayed underlined, to indicate the shortcut character (for
+Windows).
+
+At the moment, extensions cannot define whole new menus; they must define
+entries in existing menus.  Some menus are not present on some windows; such
+entry definitions are then ignored, but key bindings are still applied.  (This
+should probably be refined in the future.)
+
+Extensions are not required to define menu entries for all the events they
+implement.  (They are also not required to create keybindings, but in that
+case there must be empty bindings in cofig-extensions.def)
+
+Here is a partial example from zzdummy.py:
+
+class ZzDummy:
+
+    menudefs = [
+        ('format', [
+            ('Z in', '<<z-in>>'),
+            ('Z out', '<<z-out>>'),
+        ] )
+    ]
+
+    def __init__(self, editwin):
+        self.editwin = editwin
+
+    def z_in_event(self, event=None):
+        "...Do what you want here..."
+
+The final piece of the puzzle is the file "config-extensions.def", which is
+used to configure the loading of extensions and to establish key (or, more
+generally, event) bindings to the virtual events defined in the extensions.
+
+See the comments at the top of config-extensions.def for information.  It's
+currently necessary to manually modify that file to change IDLE's extension
+loading or extension key bindings.
+
+For further information on binding refer to the Tkinter Resources web page at
+python.org and to the Tk Command "bind" man page.

+MultiCall - a class which inherits its methods from a Tkinter widget (Text, for
+example), but enables multiple calls of functions per virtual event - all
+matching events will be called, not only the most specific one. This is done
+by wrapping the event functions - event_add, event_delete and event_info.
+MultiCall recognizes only a subset of legal event sequences. Sequences which
+are not recognized are treated by the original Tk handling mechanism. A
+more-specific event will be called before a less-specific event.
+
+The recognized sequences are complete one-event sequences (no emacs-style
+Ctrl-X Ctrl-C, no shortcuts like <3>), for all types of events.
+Key/Button Press/Release events can have modifiers.
+The recognized modifiers are Shift, Control, Option and Command for Mac, and
+Control, Alt, Shift, Meta/M for other platforms.
+
+For all events which were handled by MultiCall, a new member is added to the
+event instance passed to the binded functions - mc_type. This is one of the
+event type constants defined in this module (such as MC_KEYPRESS).
+For Key/Button events (which are handled by MultiCall and may receive
+modifiers), another member is added - mc_state. This member gives the state
+of the recognized modifiers, as a combination of the modifier constants
+also defined in this module (for example, MC_SHIFT).
+Using these members is absolutely portable.
+
+The order by which events are called is defined by these rules:
+1. A more-specific event will be called before a less-specific event.
+2. A recently-binded event will be called before a previously-binded event,
+   unless this conflicts with the first rule.
+Each function will be called at most once for each event.

+       idle  [-dns] [-t title] (-c cmd | -r file) [arg]*
+       idle  [-dns] [-t title] - [arg]*
+
+  -h         print this help message and exit
+  -n         run IDLE without a subprocess (DEPRECATED,
+             see Help/IDLE Help for details)
+
+The following options will override the IDLE 'settings' configuration:
+
+  -e         open an edit window
+  -i         open a shell window
+
+The following options imply -i and will open a shell:
+
+  -c cmd     run the command in a shell, or
+  -r file    run script from file
+
+  -d         enable the debugger
+  -s         run $IDLESTARTUP or $PYTHONSTARTUP before anything else
+  -t title   set title of shell window
+
+A default edit window will be bypassed when -c, -r, or - are used.
+
+[arg]* are passed to the command (-c) or script (-r) in sys.argv[1:].
+
+Examples:
+
+idle
+        Open an edit window or shell depending on IDLE's configuration.
+
+idle foo.py foobar.py
+        Edit the files, also open a shell if configured to start with shell.
+
+idle -est "Baz" foo.py
+        Run $IDLESTARTUP or $PYTHONSTARTUP, edit foo.py, and open a shell
+        window with the title "Baz".
+
+idle -c "import sys; print(sys.argv)" "foo"
+        Open a shell window and run the command, passing "-c" in sys.argv[0]
+        and "foo" in sys.argv[1].
+
+idle -d -s -r foo.py "Hello World"
+        Open a shell window, run a startup script, enable the debugger, and
+        run foo.py, passing "foo.py" in sys.argv[0] and "Hello World" in
+        sys.argv[1].
+
+echo "import sys; print(sys.argv)" | idle - "foobar"
+        Open a shell window, run the script piped in, passing '' in sys.argv[0]
+        and "foobar" in sys.argv[1].

+    """Support for redirecting arbitrary widget subcommands.
+
+    Some Tk operations don't normally pass through tkinter.  For example, if a
+    character is inserted into a Text widget by pressing a key, a default Tk
+    binding to the widget's 'insert' operation is activated, and the Tk library
+    processes the insert without calling back into tkinter.
+
+    Although a binding to <Key> could be made via tkinter, what we really want
+    to do is to hook the Tk 'insert' operation itself.  For one thing, we want
+    a text.insert call in idle code to have the same effect as a key press.
+
+    When a widget is instantiated, a Tcl command is created whose name is the
+    same as the pathname widget._w.  This command is used to invoke the various
+    widget operations, e.g. insert (for a Text widget). We are going to hook
+    this command and provide a facility ('register') to intercept the widget
+    operation.  We will also intercept method calls on the tkinter class
+    instance that represents the tk widget.
+
+    In IDLE, WidgetRedirector is used in Percolator to intercept Text
+    commands.  The function being registered provides access to the top
+    of a Percolator chain.  At the bottom of the chain is a call to the

+"""An IDLE extension to avoid having very long texts printed in the shell.

+A common problem in IDLE's interactive shell is printing of large amounts of
+text into the shell. This makes looking at the previous history difficult.
+Worse, this can cause IDLE to become very slow, even to the point of being
+completely unusable.
+
+This extension will automatically replace long texts with a small button.
+Double-clicking this button will remove it and insert the original text instead.
+Middle-clicking will copy the text to the clipboard. Right-clicking will open
+the text in a separate viewing window.
+
+Additionally, any output can be manually "squeezed" by the user. This includes
+output written to the standard error stream ("stderr"), such as exception
+messages and their tracebacks.
