+
+ * 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.
+

+
+ * 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.
