-
- * 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
-

-
- * AutoIndent.py, EditorWindow.py, PyShell.py:

- Tim Peters writes:

- 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>.

-
- * __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.

-
- * 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
-
- 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.

-
- * 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.

-
- * 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).

- 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:
- 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.
-
- * 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).
-
-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:
- Fix the class browser to work even when the file is not on sys.path.

-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/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.

-
- * 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.
-

-
- * 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.)

-# Extension to format a paragraph
-
-# Does basic, standard text formatting, and also understands Python
-# comment blocks. Thus, for editing Python source code, this
-# extension is really only suitable for reformatting these comment
-# blocks or triple-quoted strings.
-
-# Known problems with comment reformatting:
-# * 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
-# applied.
-# * If a comment block has leading whitespace that mixes tabs and
-# spaces, they will not be considered part of the same block.
-# * Fancy comments, like this bulleted list, arent handled :-)

-
-----------------------------------------------------------------------
-
-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.

-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 or later, so it is currently only usable
-with a Python 1.5.2 (or later) 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
-
-For feedback, please use the Python Bugs List
-(http://www.python.org/search/search_bugs.html).

-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
- - more object inspection to stack viewer, e.g. to view all array items
-- 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)
-
-- GUI form designer to kick VB's butt. (Robert Geiger)
-
-- Printing! Possibly via generation of PDF files which the user must
-then send to the printer separately. (Dinu Gherman)

-# - popup menu
-# - support partial or total redisplay
-# - key bindings (instead of quick-n-dirty bindings on Canvas):
-# - up/down arrow keys to move focus around
-# - ditto for page up/down, home/end
-# - left/right arrows to expand/collapse & move out/in
-# - more doc strings
-# - add icons for "file", "module", "class", "method"; better "python" icon
-# - callback for selection???
-# - multiple-item selection
-# - tooltips
-# - redo geometry without magic numbers
-# - keep track of object ids to allow more careful cleaning
-# - optimize tree redraw after expand of subnode

-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.txt; 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>>'),
- ])
- ]
-
- windows_keydefs = {
- '<<zoom-height>>': ['<Alt-F2>'],
- }
- unix_keydefs = {
- '<<zoom-height>>': ['<Control-z><Control-z>'],
- }
-
- def __init__(self, editwin):
- self.editwin = editwin
-
- def zoom_height_event(self, event):
- "...Do what you want here..."
-
-The final piece of the puzzle is the file "config.txt", which is used
-to to configure the loading of extensions. For each extension,
-you must include a section in config.txt (or in any of the other
-configuration files that are consulted at startup: config-unix.txt,
-config-win.txt, or ~/.idle). A section is headed by the module name
-in square brackets, e.g.
-
- [ZoomHeight]
-
-The section may be empty, or it may define configuration options for
-the extension. (See ParenMatch.py for an example.) A special option
-is 'enable': including
-
- enable = 0
-
-in a section disables that extension. More than one configuration
-file may specify options for the same extension, so a user may disable
-an extension that is loaded by default, or enable an extension that is
-disabled by default.
-
-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.

-[See end for tips.]
-
-Click on the dotted line at the top of a menu to "tear it off": a
-separate window containing the menu is created.
-
-File menu:
-
- New window -- create a new editing window
- Open... -- open an existing file
- Open module... -- open an existing module (searches sys.path)
- Class browser -- show classes and methods in current file
- Path browser -- show sys.path directories, modules, classes
- and methods
- ---
- Save -- save current window to the associated file (unsaved
- windows have a * before and after the window title)
-
- Save As... -- save current window to new file, which becomes
- the associated file
- Save Copy As... -- save current window to different file
- without changing the associated file
- ---
- Close -- close current window (asks to save if unsaved)
- Exit -- close all windows and quit IDLE (asks to save if unsaved)
-
-Edit menu:
-
- Undo -- Undo last change to current window (max 1000 changes)
- Redo -- Redo last undone change to current window
- ---
- Cut -- Copy selection into system-wide clipboard; then delete selection
- Copy -- Copy selection into system-wide clipboard
- Paste -- Insert system-wide clipboard into window
- Select All -- Select the entire contents of the edit buffer
- ---
- Find... -- Open a search dialog box with many options
- Find again -- Repeat last search
- Find selection -- Search for the string in the selection
- Find in Files... -- Open a search dialog box for searching files
- Replace... -- Open a search-and-replace dialog box
- Go to line -- Ask for a line number and show that line
- ---
- Indent region -- Shift selected lines right 4 spaces
- Dedent region -- Shift selected lines left 4 spaces
- Comment out region -- Insert ## in front of selected lines
- Uncomment region -- Remove leading # or ## from selected lines
- Tabify region -- Turns *leading* stretches of spaces into tabs
- Untabify region -- Turn *all* tabs into the right number of spaces
- Expand word -- Expand the word you have typed to match another
- word in the same buffer; repeat to get a different expansion
- Format Paragraph -- Reformat the current blank-line-separated paragraph
- ---
- Import module -- Import or reload the current module
- Run script -- Execute the current file in the __main__ namespace
-
-Windows menu:
-
- Zoom Height -- toggles the window between normal size (24x80)
- and maximum height.
- ---
- The rest of this menu lists the names of all open windows;
- select one to bring it to the foreground (deiconifying it if
- necessary).
-
-Debug menu (in the Python Shell window only):
-
- Go to file/line -- look around the insert point for a filename
- and linenumber, open the file, and show the line
- Open stack viewer -- show the stack traceback of the last exception
- Debugger toggle -- Run commands in the shell under the debugger
- JIT Stack viewer toggle -- Open stack viewer on traceback
-
-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 [Colors] section in config.txt (or add a
- [Colors] section to ~/.idle).
-
- 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:
-
- Most preferences can be changed by editing one of the
- configuration text files: config.txt (generic) or one of
- config-unix.txt, config-win.txt, config.mac.txt (platform
- specific). User-specific preferences can be stored in
- $HOME/.idle, which overrides the config*.txt files.
-
- 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.
