+
+ * 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.

+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.

+
+Wed Apr 7 18:41:59 1999 Guido van Rossum <guido@cnri.reston.va.us>

+
+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
+
+ Sinlge 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.

+
+ * 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.

+
+ * 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.

+ * ZoomHeight.py: Typo in Win specific height setting.
+
+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).

+

+ 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:
+ Fix the class browser to work even when the file is not on sys.path.
+
+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>
+

+
+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.
+
+ * Attic/PopupMenu.py: Pass a root to the help window.
+
+ * SearchBinding.py:
+ Add parent argument to 'to 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.

+"""Configuration file parser.
+
+A setup file consists of sections, lead by a "[section]" header,
+and followed by "name: value" entries, with continuations and such in
+the style of RFC 822.
+
+The option values can contain format strings which refer to other values in
+the same section, or values in a special [DEFAULT] section.
+
+For example:
+
+ something: %(dir)s/whatever
+
+would resolve the "%(dir)s" to the value of dir. All reference
+expansions are done late, on demand.
+
+Intrinsic defaults can be specified by passing them into the
+ConfigParser constructor as a dictionary.
+
+class:
+
+ConfigParser -- responsible for for parsing a list of
+ configuration files, and managing the parsed database.
+
+ methods:
+
+ __init__(defaults=None)
+ create the parser and specify a dictionary of intrinsic defaults. The
+ keys must be strings, the values must be appropriate for %()s string
+ interpolation. Note that `__name__' is always an intrinsic default;
+ it's value is the section's name.
+
+ sections()
+ return all the configuration section names, sans DEFAULT
+
+ has_section(section)
+ return whether the given section exists
+
+ options(section)
+ return list of configuration options for the named section
+
+ has_option(section, option)
+ return whether the given section has the given option
+
+ read(filenames)
+ read and parse the list of named configuration files, given by
+ name. A single filename is also allowed. Non-existing files
+ are ignored.
+
+ readfp(fp, filename=None)
+ read and parse one configuration file, given as a file object.
+ The filename defaults to fp.name; it is only used in error
+ messages (if fp has no `name' attribute, the string `<???>' is used).
+
+ get(section, option, raw=0, vars=None)
+ return a string value for the named option. All % interpolations are
+ expanded in the return values, based on the defaults passed into the
+ constructor and the DEFAULT section. Additional substitutions may be
+ provided using the `vars' argument, which must be a dictionary whose
+ contents override any pre-existing defaults.
+
+ getint(section, options)
+ like get(), but convert value to an integer
+
+ getfloat(section, options)
+ like get(), but convert value to a float
+

+"""Extension to execute a script in a separate process
+
+David Scherer <dscherer@cmu.edu>
+
+ The ExecBinding module, a replacement for ScriptBinding, executes
+ programs in a separate process. Unlike previous versions, this version
+ communicates with the user process via an RPC protocol (see the 'protocol'
+ module). The user program is loaded by the 'loader' and 'Remote'
+ modules. Its standard output and input are directed back to the
+ ExecBinding class through the RPC mechanism and implemented here.
+
+ A "stop program" command is provided and bound to control-break. Closing
+ the output window also stops the running program.

+# * If there is a selection marked, and the first line of the
+# selection is not complete, the block will probably not be detected
+# as comments, and will have the normal "text formatting" rules

+# * If a comment block has leading whitespace that mixes tabs and

+(For a more detailed change log, see the file ChangeLog.)
+
+----------------------------------------------------------------------
+
+New in IDLE 0.5 (2/15/2000)
+-------------------------
+
+Tons of stuff, much of it contributed by Tim Peters and Mark Hammond:
+
+- Status bar, displaying current line/column (Moshe Zadka).
+
+- Better stack viewer, using tree widget. (XXX Only used by Stack
+Viewer menu, not by the debugger.)
+
+- Format paragraph now recognizes Python block comments and reformats
+them correctly (MH)
+
+- New version of pyclbr.py parses top-level functions and understands
+much more of Python's syntax; this is reflected in the class and path
+browsers (TP)
+
+- Much better auto-indent; knows how to indent the insides of
+multi-line statements (TP)
+
+- Call tip window pops up when you type the name of a known function
+followed by an open parenthesis. Hit ESC or click elsewhere in the
+window to close the tip window (MH)
+
+- Comment out region now inserts ## to make it stand out more (TP)
+
+- New path and class browsers based on a tree widget that looks
+familiar to Windows users
+
+- Reworked script running commands to be more intuitive: I/O now
+always goes to the *Python Shell* window, and raw_input() works
+correctly. You use F5 to import/reload a module: this adds the module
+name to the __main__ namespace. You use Control-F5 to run a script:
+this runs the script *in* the __main__ namespace. The latter also
+sets sys.argv[] to the script name
+
+New in IDLE 0.4 (4/7/99)
+------------------------
+
+Most important change: a new menu entry "File -> Path browser", shows
+a 4-column hierarchical browser which lets you browse sys.path,
+directories, modules, and classes. Yes, it's a superset of the Class
+browser menu entry. There's also a new internal module,
+MultiScrolledLists.py, which provides the framework for this dialog.
+
+New in IDLE 0.3 (2/17/99)
+-------------------------
+
+Most important changes:
+
+- Enabled support for running a module, with or without the debugger.
+Output goes to a new window. Pressing F5 in a module is effectively a
+reload of that module; Control-F5 loads it under the debugger.
+
+- Re-enable tearing off the Windows menu, and make a torn-off Windows
+menu update itself whenever a window is opened or closed.
+
+- Menu items can now be have a checkbox (when the menu label starts
+with "!"); use this for the Debugger and "Auto-open stack viewer"
+(was: JIT stack viewer) menu items.
+
+- Added a Quit button to the Debugger API.
+
+- The current directory is explicitly inserted into sys.path.
+
+- Fix the debugger (when using Python 1.5.2b2) to use canonical
+filenames for breakpoints, so these actually work. (There's still a
+lot of work to be done to the management of breakpoints in the
+debugger though.)
+
+- Closing a window that is still colorizing now actually works.
+
+- Allow dragging of the separator between the two list boxes in the
+class browser.
+
+- Bind ESC to "close window" of the debugger, stack viewer and class
+browser. It removes the selection highlighting in regular text
+windows. (These are standard Windows conventions.)
+
+----------------------------------------------------------------------
+
+New in IDLE 0.2 (1/8/99)
+------------------------
+
+Lots of changes; here are the highlights:
+
+General:
+
+- You can now write and configure your own IDLE extension modules; see
+extend.txt.
+
+
+File menu:
+
+The command to open the Python shell window is now in the File menu.
+
+
+Edit menu:
+
+New Find dialog with more options; replace dialog; find in files dialog.
+
+Commands to tabify or untabify a region.
+
+Command to format a paragraph.
+
+
+Debug menu:
+
+JIT (Just-In-Time) stack viewer toggle -- if set, the stack viewer
+automaticall pops up when you get a traceback.
+
+Windows menu:
+
+Zoom height -- make the window full height.
+
+
+Help menu:
+
+The help text now show up in a regular window so you can search and
+even edit it if you like.
+
+----------------------------------------------------------------------
+
+IDLE 0.1 was distributed with the Python 1.5.2b1 release on 12/22/98.

+EXPERIMENTAL LOADER IDLE 2000-05-29
+-----------------------------------
+
+ David Scherer <dscherer@cmu.edu>
+
+This is a modification of the CVS version of IDLE 0.5, updated as of
+2000-03-09. It is alpha software and might be unstable. If it breaks,
+you get to keep both pieces.
+
+If you have problems or suggestions, you should either contact me or
+post to the list at http://www.python.org/mailman/listinfo/idle-dev
+(making it clear that you are using this modified version of IDLE).
+
+Changes:
+
+ The ExecBinding module, a replacement for ScriptBinding, executes
+ programs in a separate process, piping standard I/O through an RPC
+ mechanism to an OnDemandOutputWindow in IDLE. It supports executing
+ unnamed programs (through a temporary file). It does not yet support
+ debugging.
+
+ When running programs with ExecBinding, tracebacks will be clipped
+ to exclude system modules. If, however, a system module calls back
+ into the user program, that part of the traceback will be shown.
+
+ The OnDemandOutputWindow class has been improved. In particular,
+ it now supports a readline() function used to implement user input,
+ and a scroll_clear() operation which is used to hide the output of
+ a previous run by scrolling it out of the window.
+
+ Startup behavior has been changed. By default IDLE starts up with
+ just a blank editor window, rather than an interactive window. Opening
+ a file in such a blank window replaces the (nonexistent) contents of
+ that window instead of creating another window. Because of the need to
+ have a well-known port for the ExecBinding protocol, only one copy of
+ IDLE can be running. Additional invocations use the RPC mechanism to
+ report their command line arguments to the copy already running.
+
+ The menus have been reorganized. In particular, the excessively large
+ 'edit' menu has been split up into 'edit', 'format', and 'run'.
+
+ 'Python Documentation' now works on Windows, if the win32api module is
+ present.
+
+ A few key bindings have been changed: F1 now loads Python Documentation
+ instead of the IDLE help; shift-TAB is now a synonym for unindent.
+
+New modules:
+ ExecBinding.py Executes program through loader
+ loader.py Bootstraps user program
+ protocol.py RPC protocol
+ Remote.py User-process interpreter
+ spawn.py OS-specific code to start programs
+
+Files modified:
+ autoindent.py ( bindings tweaked )
+ bindings.py ( menus reorganized )
+ config.txt ( execbinding enabled )
+ editorwindow.py ( new menus, fixed 'Python Documentation' )
+ filelist.py ( hook for "open in same window" )
+ formatparagraph.py ( bindings tweaked )
+ idle.bat ( removed absolute pathname )
+ idle.pyw ( weird bug due to import with same name? )
+ iobinding.py ( open in same window, EOL convention )
+ keydefs.py ( bindings tweaked )
+ outputwindow.py ( readline, scroll_clear, etc )
+ pyshell.py ( changed startup behavior )
+ readme.txt ( <Recursion on file with id=1234567> )
+
+IDLE 0.5 - February 2000
+------------------------
+
+This is an early release of IDLE, my own attempt at a Tkinter-based
+IDE for Python.
+
+For news about this release, see the file NEWS.txt. (For a more
+detailed change log, see the file ChangeLog.)
+
+FEATURES
+
+IDLE has the following features:
+
+- coded in 100% pure Python, using the Tkinter GUI toolkit (i.e. Tcl/Tk)
+
+- cross-platform: works on Windows and Unix (on the Mac, there are
+currently problems with Tcl/Tk)
+
+- multi-window text editor with multiple undo, Python colorizing
+and many other features, e.g. smart indent and call tips
+
+- Python shell window (a.k.a. interactive interpreter)
+
+- debugger (not complete, but you can set breakpoints, view and step)
+
+USAGE
+
+The main program is in the file "idle.py"; on Unix, you should be able
+to run it by typing "./idle.py" to your shell. On Windows, you can
+run it by double-clicking it; you can use idle.pyw to avoid popping up
+a DOS console. If you want to pass command line arguments on Windows,
+use the batch file idle.bat.
+
+Command line arguments: files passed on the command line are executed,
+not opened for editing, unless you give the -e command line option.
+Try "./idle.py -h" to see other command line options.
+
+IDLE requires Python 1.5.2, so it is currently only usable with a
+Python 1.5.2 distribution. (An older version of IDLE is distributed
+with Python 1.5.2; you can drop this version on top of it.)
+
+COPYRIGHT
+
+IDLE is covered by the standard Python copyright notice
+(http://www.python.org/doc/Copyright.html).
+
+FEEDBACK
+
+(removed, since Guido probably doesn't want complaints about my
+changes)

+"""Remote
+ This module is imported by the loader and serves to control
+ the execution of the user program. It presently executes files
+ and reports exceptions to IDLE. It could be extended to provide
+ other services, such as interactive mode and debugging. To that
+ end, it could be a subclass of e.g. InteractiveInterpreter.
+
+ Two other classes, pseudoIn and pseudoOut, are file emulators also
+ used by loader.

+
+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)
+ - add a button to suppress through a specific module or class or method
+- insert the initial current directory into sys.path
+- 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
+- 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?)
+- 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:
+
+- when there's a selection, left/right arrow should go to either
+ end of the selection
+- ^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
+
+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,
+ 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?
+ - 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)
+
+- Config files still editable outside the preferences dialog.
+(Randall Hopper)
+
+- 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)
+
+- 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)

+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 extend.py; see below for details.
+
+An IDLE extension is defined by a class. Methods of the class define
+actions that are invoked by those 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 guarateed 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 bind key events. Rather, it must define
+one or more virtual events, e.g. <<zoom-height>>, and corresponding
+methods, e.g. zoom_height_event(), and have one or more class (or instance)
+variables that define mappings between virtual events and key sequences,
+e.g. <Alt-F2>. When the extension is loaded, these key sequences will
+be bound to the corresponding virtual events, and the virtual events
+will be bound to the corresponding methods. (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.)
+
+The following class or instance variables are used to define key
+bindings for virtual events:
+
+ keydefs for all platforms
+ mac_keydefs for Macintosh
+ windows_keydefs for Windows
+ unix_keydefs for Unix (and other platforms)
+
+Each of these variables, if it exists, must be a dictionary whose
+keys are virtual events, and whose values are lists of key sequences.
+
+An extension can define menu entries in a similar fashion. This is done
+with a class or instance variable named menudefs; it should be a list of
+pair, 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 the key bindings
+are still applied. (This should probably be refined in the future.)
+
+Here is a complete example example:
+
+class ZoomHeight:
+
+ menudefs = [
+ ('edit', [
+ None, # Separator
+ ('_Zoom Height', '<<zoom-height>>'),
+ ])

+
+The final piece of the puzzle is the file "extend.py", which contains a
+simple table used to configure the loading of extensions. This file
+currently contains a single list variable named "standard", which is a
+list of extension names that are to be loaded. (In the future, other
+configuration variables may be added to this module.)
+
+Extensions can define key bindings and menu entries that reference
+events they don't implement (including standard events); however this is
+not recommended (and may be forbidden in the future).
+
+Extensions are not required to define menu entries for all events they
+implement.
+
+Note: in order to change key bindings, you must currently edit the file
+keydefs. It contains two dictionaries named and formatted like the
+keydefs dictionaries described above, one for the Unix bindings and one
+for the Windows bindings. In the future, a better mechanism will be
+provided.

+
+Basic editing and navigation:
+
+ Backspace deletes to the left; DEL deletes to the right
+ Arrow keys and Page Up/Down to move around
+ Home/End go to begin/end of line
+ Control-Home/End go to begin/end of file
+ Some Emacs bindings may also work, e.g. ^B/^P/^A/^E/^D/^L
+
+Automatic indentation:
+
+ After a block-opening statement, the next line is indented by
+ 4 spaces (in the Python Shell window by one tab). After
+ certain keywords (break, return etc.) the next line is
+ dedented. In leading indentation, Backspace deletes up to 4
+ spaces if they are there. Tab inserts 1-4 spaces (in the
+ Python Shell window one tab). See also the indent/dedent
+ region commands in the edit menu.
+
+Python Shell window:
+
+ ^C interrupts executing command
+ ^D sends end-of-file; closes window if typed at >>> prompt
+
+ Command history:
+
+ Alt-p retrieves previous command matching what you have typed
+ Alt-n retrieves next
+ Return while on any previous command retrieves that command
+ Alt-/ (Expand word) is also useful here
+
+Syntax colors:
+
+ The coloring is applied in a background "thread", so you may
+ occasionally see uncolorized text. To change the color
+ scheme, edit the ColorPrefs class in IdlePrefs.py.
+
+ Python syntax colors:
+
+ Keywords orange
+ Strings green
+ Comments red
+ Definitions blue
+
+ Shell colors:
+
+ Console output brown
+ stdout blue
+ stderr dark green
+ stdin black
+
+Other preferences:
+
+ To change the font on Windows, open EditorWindow.py and change
+ text['font'] = ("lucida console", 8)
+ to, e.g.,
+ text['font'] = ("courier new", 10)
+
+ To change keyboard bindings, edit Bindings.py
+
+Command line usage:
+
+ idle.py [-c command] [-d] [-e] [-s] [-t title] [arg] ...
+
+ -c command run this command
+ -d enable debugger
+ -e edit mode; arguments are files to be edited
+ -s run $IDLESTARTUP or $PYTHONSTARTUP first
+ -t title set title of shell window
+
+ If there are arguments:
+
+ If -e is used, arguments are files opened for editing and
+ sys.argv reflects the arguments passed to IDLE itself.
+
+ Otherwise, if -c is used, all arguments are placed in
+ sys.argv[1:...], with sys.argv[0] set to '-c'.
+
+ Otherwise, if neither -e nor -c is used, the first
+ argument is a script which is executed with the remaining
+ arguments in sys.argv[1:...] and sys.argv[0] set to the
+ script name. If the script name is '-', no script is
+ executed but an interactive Python session is started; the
+ arguments are still available in sys.argv.

+"""protocol (David Scherer <dscherer@cmu.edu>)
+
+ This module implements a simple RPC or "distributed object" protocol.
+ I am probably the 100,000th person to write this in Python, but, hey,
+ it was fun.
+
+ Contents:
+
+ connectionLost is an exception that will be thrown by functions in
+ the protocol module or calls to remote methods that fail because
+ the remote program has closed the socket or because no connection
+ could be established in the first place.
+
+ Server( port=None, connection_hook=None ) creates a server on a
+ well-known port, to which clients can connect. When a client
+ connects, a Connection is created for it. If connection_hook
+ is defined, then connection_hook( socket.getpeername() ) is called
+ before a Connection is created, and if it returns false then the
+ connection is refused. connection_hook must be prepared to be
+ called from any thread.
+
+ Client( ip='127.0.0.1', port=None ) returns a Connection to a Server
+ object at a well-known address and port.
+
+ Connection( socket ) creates an RPC connection on an arbitrary socket,
+ which must already be connected to another program. You do not
+ need to use this directly if you are using Client() or Server().
+
+ publish( name, connect_function ) provides an object with the
+ specified name to some or all Connections. When another program
+ calls Connection.getobject() with the specified name, the
+ specified connect_function is called with the arguments
+
+ connect_function( conn, addr )
+
+ where conn is the Connection object to the requesting client and
+ addr is the address returned by socket.getpeername(). If that
+ function returns an object, that object becomes accessible to
+ the caller. If it returns None, the caller's request fails.
+
+ Connection objects:
+
+ .close() refuses additional RPC messages from the peer, and notifies
+ the peer that the connection has been closed. All pending remote
+ method calls in either program will fail with a connectionLost
+ exception. Further remote method calls on this connection will
+ also result in errors.
+
+ .getobject(name) returns a proxy for the remote object with the
+ specified name, if it exists and the peer permits us access.
+ Otherwise, it returns None. It may throw a connectionLost
+ exception. The returned proxy supports basic attribute access
+ and method calls, and its methods have an extra attribute,
+ .void, which is a function that has the same effect but always
+ returns None. This last capability is provided as a performance
+ hack: object.method.void(params) can return without waiting for
+ the remote process to respond, but object.method(params) needs
+ to wait for a return value or exception.
+
+ .rpc_loop(block=0) processes *incoming* messages for this connection.
+ If block=1, it continues processing until an exception or return
+ value is received, which is normally forever. Otherwise it
+ returns when all currently pending messages have been delivered.
+ It may throw a connectionLost exception.
+
+ .set_close_hook(f) specifies a function to be called when the remote
+ object closes the connection during a call to rpc_loop(). This
+ is a good way for servers to be notified when clients disconnect.
+
+ .set_shutdown_hook(f) specifies a function called *immediately* when
+ the receive loop detects that the connection has been lost. The
+ provided function must be prepared to run in any thread.
+
+ Server objects:
+
+ .rpc_loop() processes incoming messages on all connections, and
+ returns when all pending messages have been processed. It will
+ *not* throw connectionLost exceptions; the
+ Connection.set_close_hook() mechanism is much better for servers.

+"""Parse a Python file and retrieve classes and methods.
+
+Parse enough of a Python file to recognize class and method
+definitions and to find out the superclasses of a class.
+
+The interface consists of a single function:
+ readmodule(module, path)
+module is the name of a Python module, path is an optional list of
+directories where the module is to be searched. If present, path is
+prepended to the system search path sys.path.
+The return value is a dictionary. The keys of the dictionary are
+the names of the classes defined in the module (including classes
+that are defined via the from XXX import YYY construct). The values
+are class instances of the class Class defined here.
+
+A class is described by the class Class in this module. Instances
+of this class have the following instance variables:
+ name -- the name of the class
+ super -- a list of super classes (Class instances)
+ methods -- a dictionary of methods
+ file -- the file in which the class was defined
+ lineno -- the line in the file on which the class statement occurred
+The dictionary of methods uses the method names as keys and the line
+numbers on which the method was defined as values.
+If the name of a super class is not recognized, the corresponding
+entry in the list of super classes is not a class instance but a
+string giving the name of the super class. Since import statements
+are recognized and imported modules are scanned as well, this
+shouldn't happen often.
+
+BUGS
+- Continuation lines are not dealt with at all.
+- While triple-quoted strings won't confuse it, lines that look like
+ def, class, import or "from ... import" stmts inside backslash-continued
+ single-quoted strings are treated like code. The expense of stopping
+ that isn't worth it.
+- Code that doesn't pass tabnanny or python -t will confuse it, unless
+ you set the module TABWIDTH vrbl (default 8) to the correct tab width
+ for the file.
+
+PACKAGE RELATED BUGS
+- If you have a package and a module inside that or another package
+ with the same name, module caching doesn't work properly since the
+ key is the base name of the module/package.
+- The only entry that is returned when you readmodule a package is a
+ __path__ whose value is a list which confuses certain class browsers.
+- When code does:
+ from package import subpackage
+ class MyClass(subpackage.SuperClass):
+ ...
+ It can't locate the parent. It probably needs to have the same
+ hairy logic that the import locator already does. (This logic
+ exists coded in Python in the freeze package.)
