Guido van Rossum, as well as being the creator of the Python language, is the
original creator of IDLE. Other contributors prior to Version 0.8 include
Mark Hammond, Jeremy Hylton, Tim Peters, and Moshe Zadka.
Until Python 2.3, IDLE's development was carried out in the SF IDLEfork project. The
objective was to develop a version of IDLE which had an execution environment
which could be initialized prior to each run of user code.
IDLefork was merged into the Python code base in 2003.
The IDLEfork project was initiated by David Scherer, with some help from Peter
Schneider-Kamp and Nicholas Riley. David wrote the first version of the RPC
code and designed a fast turn-around environment for VPython. Guido developed
the RPC code and Remote Debugger currently integrated in IDLE. Bruce Sherwood
contributed considerable time testing and suggesting improvements.
Besides David and Guido, the main developers who were active on IDLEfork
are Stephen M. Gava, who implemented the configuration GUI, the new
configuration system, and the About dialog, and Kurt B. Kaiser, who completed
the integration of the RPC and remote debugger, implemented the threaded
subprocess, and made a number of usability enhancements.
Other contributors include Raymond Hettinger, Tony Lownds (Mac integration),
Neal Norwitz (code check and clean-up), Ronald Oussoren (Mac integration),
Noam Raphael (Code Context, Call Tips, many other patches), and Chui Tey (RPC
integration, debugger integration and persistent breakpoints).
Scott David Daniels, Tal Einat, Hernan Foffani, Christos Georgiou,
Jim Jewett, Martin v. Löwis, Jason Orendorff, Guilherme Polo, Josh Robb,
Nigel Rowe, Bruce Sherwood, Jeff Shute, and Weeble have submitted useful
patches. Thanks, guys!

IDLE History
============
This file contains the release messages for previous IDLE releases.
As you read on you go back to the dark ages of IDLE's history.
What's New in IDLEfork 0.8.1?
=============================
*Release date: 22-Jul-2001*
- New tarball released as a result of the 'revitalisation' of the IDLEfork
project.
- This release requires python 2.1 or better. Compatibility with earlier
versions of python (especially ancient ones like 1.5x) is no longer a
priority in IDLEfork development.
- This release is based on a merging of the earlier IDLE fork work with current
cvs IDLE (post IDLE version 0.8), with some minor additional coding by Kurt
B. Kaiser and Stephen M. Gava.
- This release is basically functional but also contains some known breakages,
particularly with running things from the shell window. Also the debugger is
not working, but I believe this was the case with the previous IDLE fork
release (0.7.1) as well.
- This release is being made now to mark the point at which IDLEfork is
launching into a new stage of development.
- IDLEfork CVS will now be branched to enable further development and
exploration of the two "execution in a remote process" patches submitted by
David Scherer (David's is currently in IDLEfork) and GvR, while stabilisation
and development of less heavyweight improvements (like user customisation)
can continue on the trunk.
What's New in IDLEfork 0.7.1?
==============================
*Release date: 15-Aug-2000*
- First project tarball released.
- This was the first release of IDLE fork, which at this stage was a
combination of IDLE 0.5 and the VPython idle fork, with additional changes
coded by David Scherer, Peter Schneider-Kamp and Nicholas Riley.
IDLEfork 0.7.1 - 29 May 2000
-----------------------------
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 - Release Notes
----------------------------------------
This is an early release of IDLE, my own attempt at a Tkinter-based
IDE for Python.
(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).
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.

- Allow multiple IDLE GUI/subprocess pairs to exist simultaneously. Thanks to
David Scherer for suggesting the use of an ephemeral port for the GUI.
Patch 1529142 Weeble.
- Remove port spec from run.py and fix bug where subprocess fails to
extract port from command line when warnings are present.
- Tk 8.5 Text widget requires 'wordprocessor' tabstyle attr to handle
mixed space/tab properly. Issue 5129, patch by Guilherme Polo.
- Issue #3549: On MacOS the preferences menu was not present
- IDLE would print a "Unhandled server exception!" message when internal
debugging is enabled.

in config-main.cfg remains unchanged: if set, registered exit functions will
be cleared before IDLE exits.
What's New in IDLE 2.6
======================
*Release date: 01-Oct-2008*, merged into 3.0 releases detailed above (3.0rc2)
- Issue #2665: On Windows, an IDLE installation upgraded from an old version

- 'syntax' patch adds improved calltips and a new class attribute listbox.
MultiCall module allows binding multiple actions to an event.
Patch 906702 Noam Raphael
- Better indentation after first line of string continuation.
IDLEfork Patch 681992, Noam Raphael
- Fixed CodeContext alignment problem, following suggestion from Tal Einat.
- Increased performance in CodeContext extension Patch 936169 Noam Raphael
- Mac line endings were incorrect when pasting code from some browsers
when using X11 and the Fink distribution. Python Bug 1263656.
- <Enter> when cursor is on a previous command retrieves that command. Instead
of replacing the input line, the previous command is now appended to the
input line. Indentation is preserved, and undo is enabled.
Patch 1196917 Jeff Shute
- Clarify "tab/space" Error Dialog and "Tab Width" Dialog associated with
the Untabify command.
- Corrected "tab/space" Error Dialog to show correct menu for Untabify.
Patch 1196980 Jeff Shute
- New files are colorized by default, and colorizing is removed when
saving as non-Python files. Patch 1196895 Jeff Shute
Closes Python Bugs 775012 and 800432, partial fix IDLEfork 763524
- Improve subprocess link error notification.
- run.py: use Queue's blocking feature instead of sleeping in the main
loop. Patch # 1190163 Michiel de Hoon
- Add config-main option to make the 'history' feature non-cyclic.
Default remains cyclic. Python Patch 914546 Noam Raphael.
- Removed ability to configure tabs indent from Options dialog. This 'feature'
has never worked and no one has complained. It is still possible to set a
default tabs (v. spaces) indent 'manually' via config-main.def (or to turn on
tabs for the current EditorWindow via the Format menu) but IDLE will
encourage indentation via spaces.
- Enable setting the indentation width using the Options dialog.
Bug # 783877
- Add keybindings for del-word-left and del-word-right.
- Discourage using an indent width other than 8 when using tabs to indent
Python code.
- Restore use of EditorWindow.set_indentation_params(), was dead code since
Autoindent was merged into EditorWindow. This allows IDLE to conform to the
indentation width of a loaded file. (But it still will not switch to tabs
even if the file uses tabs.) Any change in indent width is local to that
window.
- Add Tabnanny check before Run/F5, not just when Checking module.
- If an extension can't be loaded, print warning and skip it instead of
erroring out.
- Improve error handling when .idlerc can't be created (warn and exit).
- The GUI was hanging if the shell window was closed while a raw_input()
was pending. Restored the quit() of the readline() mainloop().
http://mail.python.org/pipermail/idle-dev/2004-December/002307.html
- The remote procedure call module rpc.py can now access data attributes of
remote registered objects. Changes to these attributes are local, however.
What's New in IDLE 1.1?
=======================
*Release date: 30-NOV-2004*
- On OpenBSD, terminating IDLE with ctrl-c from the command line caused a
stuck subprocess MainThread because only the SocketThread was exiting.
- Saving a Keyset w/o making changes (by using the "Save as New Custom Key Set"
button) caused IDLE to fail on restart (no new keyset was created in
config-keys.cfg). Also true for Theme/highlights. Python Bug 1064535.
- A change to the linecache.py API caused IDLE to exit when an exception was
raised while running without the subprocess (-n switch). Python Bug 1063840.
- When paragraph reformat width was made configurable, a bug was
introduced that caused reformatting of comment blocks to ignore how
far the block was indented, effectively adding the indentation width
to the reformat width. This has been repaired, and the reformat
width is again a bound on the total width of reformatted lines.
- Improve keyboard focus binding, especially in Windows menu. Improve
window raising, especially in the Windows menu and in the debugger.
IDLEfork 763524.
- If user passes a non-existent filename on the commandline, just
open a new file, don't raise a dialog. IDLEfork 854928.
- EditorWindow.py was not finding the .chm help file on Windows. Typo
at Rev 1.54. Python Bug 990954
- checking sys.platform for substring 'win' was breaking IDLE docs on Mac
(darwin). Also, Mac Safari browser requires full file:// URIs. SF 900580.
- Redirect the warning stream to the shell during the ScriptBinding check of
user code and format the warning similarly to an exception for both that
check and for runtime warnings raised in the subprocess.
- CodeContext hint pane visibility state is now persistent across sessions.
The pane no longer appears in the shell window. Added capability to limit
extensions to shell window or editor windows. Noam Raphael addition
to Patch 936169.
- Paragraph reformat width is now a configurable parameter in the
Options GUI.
- New Extension: CodeContext. Provides block structuring hints for code
which has scrolled above an edit window. Patch 936169 Noam Raphael.
- If nulls somehow got into the strings in recent-files.lst
EditorWindow.update_recent_files_list() was failing. Python Bug 931336.
- If the normal background is changed via Configure/Highlighting, it will
update immediately, thanks to the previously mentioned patch by Nigel Rowe.
- Add a highlight theme for builtin keywords. Python Patch 805830 Nigel Rowe
This also fixed IDLEfork bug [ 693418 ] Normal text background color not
refreshed and Python bug [897872 ] Unknown color name on HP-UX
- rpc.py:SocketIO - Large modules were generating large pickles when downloaded
to the execution server. The return of the OK response from the subprocess
initialization was interfering and causing the sending socket to be not
ready. Add an IO ready test to fix this. Moved the polling IO ready test
into pollpacket().
- Fix typo in rpc.py, s/b "pickle.PicklingError" not "pickle.UnpicklingError".
- Added a Tk error dialog to run.py inform the user if the subprocess can't
connect to the user GUI process. Added a timeout to the GUI's listening
socket. Added Tk error dialogs to PyShell.py to announce a failure to bind
the port or connect to the subprocess. Clean up error handling during
connection initiation phase. This is an update of Python Patch 778323.
- Print correct exception even if source file changed since shell was
restarted. IDLEfork Patch 869012 Noam Raphael
- Keybindings with the Shift modifier now work correctly. So do bindings which
use the Space key. Limit unmodified user keybindings to the function keys.
Python Bug 775353, IDLEfork Bugs 755647, 761557
- After an exception, run.py was not setting the exception vector. Noam
Raphael suggested correcting this so pdb's postmortem pm() would work.
IDLEfork Patch 844675
- IDLE now does not fail to save the file anymore if the Tk buffer is not a
Unicode string, yet eol_convention is. Python Bugs 774680, 788378
- IDLE didn't start correctly when Python was installed in "Program Files" on
W2K and XP. Python Bugs 780451, 784183
- config-main.def documentation incorrectly referred to idle- instead of
config- filenames. SF 782759 Also added note about .idlerc location.
What's New in IDLE 1.0?
=======================
*Release date: 29-Jul-2003*
- Added a banner to the shell discussing warnings possibly raised by personal
firewall software. Added same comment to README.txt.
- Calltip error when docstring was None Python Bug 775541
- Updated extend.txt, help.txt, and config-extensions.def to correctly
reflect the current status of the configuration system. Python Bug 768469
- Fixed: Call Tip Trimming May Loop Forever. Python Patch 769142 (Daniels)
- Replaced apply(f, args, kwds) with f(*args, **kwargs) to improve performance
Python Patch 768187
- Break or continue statements outside a loop were causing IDLE crash
Python Bug 767794
- Convert Unicode strings from readline to IOBinding.encoding. Also set
sys.std{in|out|err}.encoding, for both the local and the subprocess case.
SF IDLEfork patch 682347.
- Extend AboutDialog.ViewFile() to support file encodings. Make the CREDITS
file Latin-1.
- Updated the About dialog to reflect re-integration into Python. Provide
buttons to display Python's NEWS, License, and Credits, plus additional
buttons for IDLE's README and NEWS.
- TextViewer() now has a third parameter which allows inserting text into the
viewer instead of reading from a file.
- (Created the .../Lib/idlelib directory in the Python CVS, which is a clone of
IDLEfork modified to install in the Python environment. The code in the
interrupt module has been moved to thread.interrupt_main(). )
- Printing the Shell window was failing if it was not saved first SF 748975
- When using the Search in Files dialog, if the user had a selection
highlighted in his Editor window, insert it into the dialog search field.
- The Python Shell entry was disappearing from the Windows menu.
- Update the Windows file list when a file name change occurs
- Change to File / Open Module: always pop up the dialog, using the current
selection as the default value. This is easier to use habitually.
- Avoided a problem with starting the subprocess when 'localhost' doesn't
resolve to the user's loopback interface. SF 747772
- Fixed an issue with highlighted errors never de-colorizing. SF 747677. Also
improved notification of Tabnanny Token Error.
- File / New will by default save in the directory of the Edit window from
which it was initiated. SF 748973 Guido van Rossum patch.
What's New in IDLEfork 0.9b1?
=============================
*Release date: 02-Jun-2003*
- The current working directory of the execution environment (and shell
following completion of execution) is now that of the module being run.
- Added the delete-exitfunc option to config-main.def. (This option is not
included in the Options dialog.) Setting this to True (the default) will
cause IDLE to not run sys.exitfunc/atexit when the subprocess exits.
- IDLE now preserves the line ending codes when editing a file produced on
a different platform. SF 661759, SF 538584
- Reduced default editor font size to 10 point and increased window height
to provide a better initial impression on Windows.
- Options / Fonts/Tabs / Set Base Editor Font: List box was not highlighting
the default font when first installed on Windows. SF 661676
- Added Autosave feature: when user runs code from edit window, if the file
has been modified IDLE will silently save it if Autosave is enabled. The
option is set in the Options dialog, and the default is to prompt the
user to save the file. SF 661318 Bruce Sherwood patch.
- Improved the RESTART annotation in the shell window when the user restarts
the shell while it is generating output. Also improved annotation when user
repeatedly hammers the Ctrl-F6 restart.
- Allow IDLE to run when not installed and cwd is not the IDLE directory
SF Patch 686254 "Run IDLEfork from any directory without set-up" - Raphael
- When a module is run from an EditorWindow: if its directory is not in
sys.path, prepend it. This allows the module to import other modules in
the same directory. Do the same for a script run from the command line.
- Correctly restart the subprocess if it is running user code and the user
attempts to run some other module or restarts the shell. Do the same if
the link is broken and it is possible to restart the subprocess and re-
connect to the GUI. SF RFE 661321.
- Improved exception reporting when running commands or scripts from the
command line.
- Added a -n command line switch to start IDLE without the subprocess.
Removed the Shell menu when running in that mode. Updated help messages.
- Added a comment to the shell startup header to indicate when IDLE is not
using the subprocess.
- Restore the ability to run without the subprocess. This can be important for
some platforms or configurations. (Running without the subprocess allows the
debugger to trace through parts of IDLE itself, which may or may not be
desirable, depending on your point of view. In addition, the traditional
reload/import tricks must be use if user source code is changed.) This is
helpful for developing IDLE using IDLE, because one instance can be used to
edit the code and a separate instance run to test changes. (Multiple
concurrent IDLE instances with subprocesses is a future feature)
- Improve the error message a user gets when saving a file with non-ASCII
characters and no source encoding is specified. Done by adding a dialog
'EncodingMessage', which contains the line to add in a fixed-font entry
widget, and which has a button to add that line to the file automatically.
Also, add a configuration option 'EditorWindow/encoding', which has three
possible values: none, utf-8, and locale. None is the default: IDLE will show
this dialog when non-ASCII characters are encountered. utf-8 means that files
with non-ASCII characters are saved as utf-8-with-bom. locale means that
files are saved in the locale's encoding; the dialog is only displayed if the
source contains characters outside the locale's charset. SF 710733 - Loewis
- Improved I/O response by tweaking the wait parameter in various
calls to signal.signal().
- Implemented a threaded subprocess which allows interrupting a pass
loop in user code using the 'interrupt' extension. User code runs
in MainThread, while the RPCServer is handled by SockThread. This is
necessary because Windows doesn't support signals.
- Implemented the 'interrupt' extension module, which allows a subthread
to raise a KeyboardInterrupt in the main thread.
- Attempting to save the shell raised an error related to saving
breakpoints, which are not implemented in the shell
- Provide a correct message when 'exit' or 'quit' are entered at the
IDLE command prompt SF 695861
- Eliminate extra blank line in shell output caused by not flushing
stdout when user code ends with an unterminated print. SF 695861
- Moved responsibility for exception formatting (i.e. pruning IDLE internal
calls) out of rpc.py into the client and server.
- Exit IDLE cleanly even when doing subprocess I/O
- Handle subprocess interrupt with an RPC message.
- Restart the subprocess if it terminates itself. (VPython programs do that)
- Support subclassing of exceptions, including in the shell, by moving the
exception formatting to the subprocess.
What's New in IDLEfork 0.9 Alpha 2?
===================================
*Release date: 27-Jan-2003*
- Updated INSTALL.txt to claify use of the python2 rpm.
- Improved formatting in IDLE Help.
- Run menu: Replace "Run Script" with "Run Module".
- Code encountering an unhandled exception under the debugger now shows
the correct traceback, with IDLE internal levels pruned out.
- If an exception occurs entirely in IDLE, don't prune the IDLE internal
modules from the traceback displayed.
- Class Browser and Path Browser now use Alt-Key-2 for vertical zoom.
- IDLE icons will now install correctly even when setup.py is run from the
build directory
- Class Browser now compatible with Python2.3 version of pyclbr.py
- Left cursor move in presence of selected text now moves from left end
of the selection.
- Add Meta keybindings to "IDLE Classic Windows" to handle reversed
Alt/Meta on some Linux distros.
- Change default: IDLE now starts with Python Shell.
- Removed the File Path from the Additional Help Sources scrolled list.
- Add capability to access Additional Help Sources on the web if the
Help File Path begins with //http or www. (Otherwise local path is
validated, as before.)
- Additional Help Sources were not being posted on the Help menu in the
order entered. Implement sorting the list by [HelpFiles] 'option'
number.
- Add Browse button to New Help Source dialog. Arrange to start in
Python/Doc if platform is Windows, otherwise start in current directory.
- Put the Additional Help Sources directly on the Help menu instead of in
an Extra Help cascade menu. Rearrange the Help menu so the Additional
Help Sources come last. Update help.txt appropriately.
- Fix Tk root pop-ups in configSectionNameDialog.py and configDialog.py
- Uniform capitalization in General tab of ConfigDialog, update the doc string.
- Fix bug in ConfigDialog where SaveAllChangedConfig() was unexpectedly
deleting Additional Help Sources from the user's config file.
- Make configHelpSourceEdit OK button the default and bind <Return>
- Fix Tk root pop-ups in configHelpSourceEdit: error dialogs not attached
to parents.
- Use os.startfile() to open both Additional Help and Python Help on the
Windows platform. The application associated with the file type will act as
the viewer. Windows help files (.chm) are now supported via the
Settings/General/Additional Help facility.
- If Python Help files are installed locally on Linux, use them instead of
accessing python.org.
- Make the methods for finding the Python help docs more robust, and make
them work in the installed configuration, also.
- On the Save Before Run dialog, make the OK button the default. One
less mouse action!
- Add a method: EditorWindow.get_geometry() for future use in implementing
window location persistence.
- Removed the "Help/Advice" menu entry. Thanks, David! We'll remember!
- Change the "Classic Windows" theme's paste key to be <ctrl-v>.
- Rearrange the Shell menu to put Stack Viewer entries adjacent.
- Add the ability to restart the subprocess interpreter from the shell window;
add an associated menu entry "Shell/Restart" with binding Control-F6. Update
IDLE help.
- Upon a restart, annotate the shell window with a "restart boundary". Add a
shell window menu "Shell/View Restart" with binding F6 to jump to the most
recent restart boundary.
- Add Shell menu to Python Shell; change "Settings" to "Options".
- Remove incorrect comment in setup.py: IDLEfork is now installed as a package.
- Add INSTALL.txt, HISTORY.txt, NEWS.txt to installed configuration.
- In installer text, fix reference to Visual Python, should be VPython.
Properly credit David Scherer.
- Modified idle, idle.py, idle.pyw to improve exception handling.
What's New in IDLEfork 0.9 Alpha 1?
===================================
*Release date: 31-Dec-2002*
- First release of major new functionality. For further details refer to
Idle-dev and/or the Sourceforge CVS.
- Adapted to the Mac platform.
- Overhauled the IDLE startup options and revised the idle -h help message,
which provides details of command line usage.
- Multiple bug fixes and usability enhancements.
- Introduced the new RPC implementation, which includes a debugger. The output
of user code is to the shell, and the shell may be used to inspect the
environment after the run has finished. (In version 0.8.1 the shell
environment was separate from the environment of the user code.)
- Introduced the configuration GUI and a new About dialog.
- Removed David Scherer's Remote Procedure Call code and replaced with Guido
van Rossum's. GvR code has support for the IDLE debugger and uses the shell
to inspect the environment of code Run from an Edit window. Files removed:
ExecBinding.py, loader.py, protocol.py, Remote.py, spawn.py

IDLE MENUS
==========
Top level items and most submenu items are defined in mainmenu.
Extensions add submenu items when active. The names given are
found, quoted, in one of these modules, paired with a '<<pseudoevent>>'.
Each pseudoevent is bound to an event handler. Some event handlers
call another function that does the actual work. The annotations below
are intended to at least give the module where the actual work is done.

OTHER TOPICS
============
Generally use PEP 8.
import statements
-----------------
Put imports at the top, unless there is a good reason otherwise.
PEP 8 says to group stdlib, 3rd-party dependencies, and package imports.
For idlelib, the groups are general stdlib, tkinter, and idlelib.
Sort modules within each group, except that tkinter.ttk follows tkinter.
Sort 'from idlelib import mod1' and 'from idlelib.mod2 import object'
together by module, ignoring within module objects.
Put 'import __main__' after other idlelib imports.
Imports only needed for testing are put not at the top but in an
htest function def or "if __name__ == '__main__'" clause.
Within module imports like "from idlelib.mod import class" may cause
circular imports to deadlock. Even without this, circular imports may
require at least one of the imports to be delayed until a function call.
What's New entries
------------------
Repository directory Doc/whatsnew/ has a file 3.n.rst for each 3.n
Python version. For the first entry in each file, add subsection
'IDLE and idlelib', in alphabetical position, to the 'Improved Modules'
section. For the rest of cpython, entries to 3.(n+1).rst begin with
the release of 3.n.0b1. For IDLE, entries for features backported from
'main' to '3.n' during its beta period do not got in 3.(n+1).rst. The
latter usually gets its first entry during the 3.n.0 candidate period
or after the 3.n.0 release.
When, as per PEP 434, feature changes are backported, entries are placed
in the 3.n.rst file *in the main branch* for each Python version n that
gets the backport. (Note: the format of entries have varied between
versions.) Add a line "New in 3.n maintenance releases." before the
first back-ported feature after 3.n.0 is released. Since each older
version file gets a different number of backports, it is easiest to
make a separate PR for each file and label it with the backports
needed.
Github repository and issues
----------------------------
The CPython repository is https://github.com/python/cpython. The
IDLE Issues listing is https://github.com/orgs/python/projects/31.
The main classification is by Topic, based on the IDLE menu. View the
topics list by clicking the [<]] button in the upper right.

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