    103 
    104 - Configured selection highlighting colors were ignored; updating highlighting

    137 - OSX: Avoid crash for those versions of Tcl/Tk which don't have a console
    138 
    139 - Bug in idlelib.MultiCall: Options dialog was crashing IDLE if there was an
    140   option in config-extensions w/o a value. Patch #1672481, Tal Einat
    141 
    142 - Corrected some bugs in AutoComplete.  Also, Page Up/Down in ACW implemented;
    143   mouse and cursor selection in ACWindow implemented; double Tab inserts
    144   current selection and closes ACW (similar to double-click and Return); scroll
    145   wheel now works in ACW.  Added AutoComplete instructions to IDLE Help.
    146 
    147 - AutoCompleteWindow moved below input line, will move above if there
    148   isn't enough space.  Patch 1621265 Tal Einat
    149 
    150 - Calltips now 'handle' tuples in the argument list (display '<tuple>' :)
    151   Suggested solution by Christos Georgiou, Bug 791968.
    152 
    153 - Add 'raw' support to configHandler. Patch 1650174 Tal Einat.

    156

    161   is started with that option.
    162 
    163 - Honor the "Cancel" action in the save dialog (Debian bug #299092)
    164 
    165 - Some syntax errors were being caught by tokenize during the tabnanny
    166   check, resulting in obscure error messages.  Do the syntax check
    167   first.  Bug 1562716, 1562719
    168 
    169 - IDLE's version number takes a big jump to match the version number of
    170   the Python release of which it's a part.
    171 
    172

    195   (since 1.2a1) Patch 1528468 Tal Einat.
    196 
    197 - Changing tokenize (39046) to detect dedent broke tabnanny check (since 1.2a1)
    198 
    199 - ToggleTab dialog was setting indent to 8 even if cancelled (since 1.2a1).
    200 
    201 - When used w/o subprocess, all exceptions were preceded by an error
    202   message claiming they were IDLE internal errors (since 1.2a1).
    203 
    204 What's New in IDLE 1.2b3?
    205 =========================
    206 
    207 *Release date: 03-AUG-2006*
    208 
    209 - Bug #1525817: Don't truncate short lines in IDLE's tool tips.
    210

    231 
    232 What's New in IDLE 1.2b2?

    239 
    240 *Release date: 20-JUN-2006*

    243 =========================
    244 
    245 *Release date: 27-APR-2006*
    246 
    247 What's New in IDLE 1.2a1?
    248 =========================
    249 
    250 *Release date: 05-APR-2006*
    251 
    252 - Patch #1162825: Support non-ASCII characters in IDLE window titles.
    253 
    254 - Source file f.flush() after writing; trying to avoid lossage if user
    255   kills GUI.
    256 
    257 - Options / Keys / Advanced dialog made functional.  Also, allow binding
    258   of 'movement' keys.
    259 
    260 - 'syntax' patch adds improved calltips and a new class attribute listbox.
    261   MultiCall module allows binding multiple actions to an event.
    262   Patch 906702 Noam Raphael
    263 
    264 - Better indentation after first line of string continuation.
    265   IDLEfork Patch 681992, Noam Raphael
    266 
    267 - Fixed CodeContext alignment problem, following suggestion from Tal Einat.
    268 
    269 - Increased performance in CodeContext extension  Patch 936169 Noam Raphael
    270 
    271 - Mac line endings were incorrect when pasting code from some browsers
    272   when using X11 and the Fink distribution.  Python Bug 1263656.
    273 
    274 - <Enter> when cursor is on a previous command retrieves that command.  Instead
    275   of replacing the input line, the previous command is now appended to the
    276   input line. Indentation is preserved, and undo is enabled.
    277   Patch 1196917  Jeff Shute
    278 
    279 - Clarify "tab/space" Error Dialog and "Tab Width" Dialog associated with
    280   the Untabify command.
    281 
    282 - Corrected "tab/space" Error Dialog to show correct menu for Untabify.
    283   Patch 1196980 Jeff Shute
    284 
    285 - New files are colorized by default, and colorizing is removed when
    286   saving as non-Python files. Patch 1196895 Jeff Shute
    287   Closes Python Bugs 775012 and 800432, partial fix IDLEfork 763524
    288 
    289 - Improve subprocess link error notification.
    290 
    291 - run.py: use Queue's blocking feature instead of sleeping in the main
    292   loop.  Patch # 1190163 Michiel de Hoon
    293 
    294 - Add config-main option to make the 'history' feature non-cyclic.
    295   Default remains cyclic.  Python Patch 914546 Noam Raphael.
    296 
    297 - Removed ability to configure tabs indent from Options dialog.  This 'feature'
    298   has never worked and no one has complained.  It is still possible to set a
    299   default tabs (v. spaces) indent 'manually' via config-main.def (or to turn on
    300   tabs for the current EditorWindow via the Format menu) but IDLE will
    301   encourage indentation via spaces.
    302 
    303 - Enable setting the indentation width using the Options dialog.
    304   Bug # 783877
    305 
    306 - Add keybindings for del-word-left and del-word-right.
    307 
    308 - Discourage using an indent width other than 8 when using tabs to indent
    309   Python code.
    310 
    311 - Restore use of EditorWindow.set_indentation_params(), was dead code since
    312   Autoindent was merged into EditorWindow.  This allows IDLE to conform to the
    313   indentation width of a loaded file.  (But it still will not switch to tabs
    314   even if the file uses tabs.)  Any change in indent width is local to that
    315   window.
    316 
    317 - Add Tabnanny check before Run/F5, not just when Checking module.
    318 
    319 - If an extension can't be loaded, print warning and skip it instead of
    320   erroring out.
    321 
    322 - Improve error handling when .idlerc can't be created (warn and exit).
    323 
    324 - The GUI was hanging if the shell window was closed while a raw_input()
    325   was pending.  Restored the quit() of the readline() mainloop().
    326   http://mail.python.org/pipermail/idle-dev/2004-December/002307.html
    327 
    328 - The remote procedure call module rpc.py can now access data attributes of
    329   remote registered objects.  Changes to these attributes are local, however.
    330 
    331 What's New in IDLE 1.1?
    332 =======================
    333 
    334 *Release date: 30-NOV-2004*
    335 
    336 - On OpenBSD, terminating IDLE with ctrl-c from the command line caused a
    337   stuck subprocess MainThread because only the SocketThread was exiting.
    338 
    339 What's New in IDLE 1.1b3/rc1?
    340 =============================
    341 
    342 *Release date: 18-NOV-2004*
    343 
    344 - Saving a Keyset w/o making changes (by using the "Save as New Custom Key Set"
    345   button) caused IDLE to fail on restart (no new keyset was created in
    346   config-keys.cfg).  Also true for Theme/highlights.  Python Bug 1064535.
    347 
    348 - A change to the linecache.py API caused IDLE to exit when an exception was
    349   raised while running without the subprocess (-n switch).  Python Bug 1063840.
    350 
    351 What's New in IDLE 1.1b2?
    352 =========================
    353 
    354 *Release date: 03-NOV-2004*
    355 
    356 - When paragraph reformat width was made configurable, a bug was
    357   introduced that caused reformatting of comment blocks to ignore how
    358   far the block was indented, effectively adding the indentation width
    359   to the reformat width.  This has been repaired, and the reformat
    360   width is again a bound on the total width of reformatted lines.
    361 
    362 What's New in IDLE 1.1b1?
    363 =========================
    364

    374   window raising, especially in the Windows menu and in the debugger.
    375   IDLEfork 763524.
    376 
    377 - If user passes a non-existent filename on the commandline, just
    378   open a new file, don't raise a dialog.  IDLEfork 854928.
    379 
    380 
    381 What's New in IDLE 1.1a2?
    382 =========================
    383 
    384 *Release date: 05-AUG-2004*
    385 
    386 - EditorWindow.py was not finding the .chm help file on Windows.  Typo
    387   at Rev 1.54.  Python Bug 990954
    388 
    389 - checking sys.platform for substring 'win' was breaking IDLE docs on Mac
    390   (darwin).  Also, Mac Safari browser requires full file:// URIs.  SF 900580.
    391 
    392 
    393 What's New in IDLE 1.1a1?
    394 =========================
    395 
    396 *Release date: 08-JUL-2004*
    397 
    398 - Redirect the warning stream to the shell during the ScriptBinding check of
    399   user code and format the warning similarly to an exception for both that
    400   check and for runtime warnings raised in the subprocess.
    401 
    402 - CodeContext hint pane visibility state is now persistent across sessions.
    403   The pane no longer appears in the shell window.  Added capability to limit
    404   extensions to shell window or editor windows.  Noam Raphael addition
    405   to Patch 936169.
    406 
    407 - Paragraph reformat width is now a configurable parameter in the
    408   Options GUI.
    409 
    410 - New Extension: CodeContext.  Provides block structuring hints for code
    411   which has scrolled above an edit window. Patch 936169 Noam Raphael.
    412 
    413 - If nulls somehow got into the strings in recent-files.lst
    414   EditorWindow.update_recent_files_list() was failing.  Python Bug 931336.
    415 
    416 - If the normal background is changed via Configure/Highlighting, it will
    417   update immediately, thanks to the previously mentioned patch by Nigel Rowe.
    418 
    419 - Add a highlight theme for builtin keywords.  Python Patch 805830 Nigel Rowe
    420   This also fixed IDLEfork bug [ 693418 ] Normal text background color not
    421   refreshed and Python bug [897872 ] Unknown color name on HP-UX
    422 
    423 - rpc.py:SocketIO - Large modules were generating large pickles when downloaded
    424   to the execution server.  The return of the OK response from the subprocess
    425   initialization was interfering and causing the sending socket to be not
    426   ready.  Add an IO ready test to fix this.  Moved the polling IO ready test
    427   into pollpacket().
    428 
    429 - Fix typo in rpc.py, s/b "pickle.PicklingError" not "pickle.UnpicklingError".
    430 
    431 - Added a Tk error dialog to run.py inform the user if the subprocess can't
    432   connect to the user GUI process.  Added a timeout to the GUI's listening
    433   socket.  Added Tk error dialogs to PyShell.py to announce a failure to bind
    434   the port or connect to the subprocess.  Clean up error handling during
    435   connection initiation phase.  This is an update of Python Patch 778323.
    436 
    437 - Print correct exception even if source file changed since shell was
    438   restarted.  IDLEfork Patch 869012 Noam Raphael
    439 
    440 - Keybindings with the Shift modifier now work correctly.  So do bindings which
    441   use the Space key.  Limit unmodified user keybindings to the function keys.
    442   Python Bug 775353, IDLEfork Bugs 755647, 761557
    443 
    444 - After an exception, run.py was not setting the exception vector. Noam
    445   Raphael suggested correcting this so pdb's postmortem pm() would work.
    446   IDLEfork Patch 844675
    447 
    448 - IDLE now does not fail to save the file anymore if the Tk buffer is not a
    449   Unicode string, yet eol_convention is.  Python Bugs 774680, 788378
    450 
    451 - IDLE didn't start correctly when Python was installed in "Program Files" on
    452   W2K and XP.  Python Bugs 780451, 784183
    453 
    454 - config-main.def documentation incorrectly referred to idle- instead of
    455   config-  filenames.  SF 782759  Also added note about .idlerc location.

    494 
    495 
    496 What's New in IDLE 1.0b2?
    497 =========================
    498 
    499 *Release date: 29-Jun-2003*
    500 
    501 - Extend AboutDialog.ViewFile() to support file encodings.  Make the CREDITS
    502   file Latin-1.
    503 
    504 - Updated the About dialog to reflect re-integration into Python.  Provide
    505   buttons to display Python's NEWS, License, and Credits, plus additional
    506   buttons for IDLE's README and NEWS.
    507 
    508 - TextViewer() now has a third parameter which allows inserting text into the
    509   viewer instead of reading from a file.
    510 
    511 - (Created the .../Lib/idlelib directory in the Python CVS, which is a clone of
    512   IDLEfork modified to install in the Python environment.  The code in the
    513   interrupt module has been moved to thread.interrupt_main(). )
    514 
    515 - Printing the Shell window was failing if it was not saved first SF 748975
    516 
    517 - When using the Search in Files dialog, if the user had a selection
    518   highlighted in his Editor window, insert it into the dialog search field.
    519 
    520 - The Python Shell entry was disappearing from the Windows menu.
    521 
    522 - Update the Windows file list when a file name change occurs
    523 
    524 - Change to File / Open Module: always pop up the dialog, using the current
    525   selection as the default value.  This is easier to use habitually.
    526 
    527 - Avoided a problem with starting the subprocess when 'localhost' doesn't
    528   resolve to the user's loopback interface.  SF 747772
    529 
    530 - Fixed an issue with highlighted errors never de-colorizing.  SF 747677.  Also
    531   improved notification of Tabnanny Token Error.
    532 
    533 - File / New will by default save in the directory of the Edit window from
    534   which it was initiated.  SF 748973 Guido van Rossum patch.
    535 
    536 
    537 What's New in IDLEfork 0.9b1?
    538 =============================
    539 
    540 *Release date: 02-Jun-2003*
    541 
    542 - The current working directory of the execution environment (and shell
    543   following completion of execution) is now that of the module being run.
    544 
    545 - Added the delete-exitfunc option to config-main.def.  (This option is not
    546   included in the Options dialog.)  Setting this to True (the default) will
    547   cause IDLE to not run sys.exitfunc/atexit when the subprocess exits.
    548 
    549 - IDLE now preserves the line ending codes when editing a file produced on
    550   a different platform. SF 661759,  SF 538584
    551 
    552 - Reduced default editor font size to 10 point and increased window height
    553   to provide a better initial impression on Windows.
    554 
    555 - Options / Fonts/Tabs / Set Base Editor Font: List box was not highlighting
    556   the default font when first installed on Windows.  SF 661676
    557 
    558 - Added Autosave feature: when user runs code from edit window, if the file
    559   has been modified IDLE will silently save it if Autosave is enabled.  The
    560   option is set in the Options dialog, and the default is to prompt the
    561   user to save the file.   SF 661318 Bruce Sherwood patch.
    562 
    563 - Improved the RESTART annotation in the shell window when the user restarts
    564   the shell while it is generating output.  Also improved annotation when user
    565   repeatedly hammers the Ctrl-F6 restart.
    566 
    567 - Allow IDLE to run when not installed and cwd is not the IDLE directory
    568   SF Patch 686254 "Run IDLEfork from any directory without set-up" - Raphael
    569 
    570 - When a module is run from an EditorWindow: if its directory is not in
    571   sys.path, prepend it.  This allows the module to import other modules in
    572   the same directory.  Do the same for a script run from the command line.
    573 
    574 - Correctly restart the subprocess if it is running user code and the user
    575   attempts to run some other module or restarts the shell.  Do the same if
    576   the link is broken and it is possible to restart the subprocess and re-
    577   connect to the GUI.   SF RFE 661321.
    578 
    579 - Improved exception reporting when running commands or scripts from the
    580   command line.
    581 
    582 - Added a -n command line switch to start IDLE without the subprocess.
    583   Removed the Shell menu when running in that mode.  Updated help messages.
    584 
    585 - Added a comment to the shell startup header to indicate when IDLE is not
    586   using the subprocess.
    587 
    588 - Restore the ability to run without the subprocess.  This can be important for
    589   some platforms or configurations.  (Running without the subprocess allows the
    590   debugger to trace through parts of IDLE itself, which may or may not be
    591   desirable, depending on your point of view.  In addition, the traditional
    592   reload/import tricks must be use if user source code is changed.)  This is
    593   helpful for developing IDLE using IDLE, because one instance can be used to
    594   edit the code and a separate instance run to test changes.  (Multiple
    595   concurrent IDLE instances with subprocesses is a future feature)
    596 
    597 - Improve the error message a user gets when saving a file with non-ASCII
    598   characters and no source encoding is specified.  Done by adding a dialog
    599   'EncodingMessage', which contains the line to add in a fixed-font entry
    600   widget, and which has a button to add that line to the file automatically.
    601   Also, add a configuration option 'EditorWindow/encoding', which has three
    602   possible values: none, utf-8, and locale. None is the default: IDLE will show
    603   this dialog when non-ASCII characters are encountered. utf-8 means that files
    604   with non-ASCII characters are saved as utf-8-with-bom. locale means that
    605   files are saved in the locale's encoding; the dialog is only displayed if the
    606   source contains characters outside the locale's charset.  SF 710733 - Loewis
    607 
    608 - Improved I/O response by tweaking the wait parameter in various
    609   calls to signal.signal().
    610 
    611 - Implemented a threaded subprocess which allows interrupting a pass
    612   loop in user code using the 'interrupt' extension.  User code runs
    613   in MainThread, while the RPCServer is handled by SockThread.  This is
    614   necessary because Windows doesn't support signals.
    615 
    616 - Implemented the 'interrupt' extension module, which allows a subthread
    617   to raise a KeyboardInterrupt in the main thread.
    618 
    619 - Attempting to save the shell raised an error related to saving
    620   breakpoints, which are not implemented in the shell
    621 
    622 - Provide a correct message when 'exit' or 'quit' are entered at the
    623   IDLE command prompt  SF 695861
    624 
    625 - Eliminate extra blank line in shell output caused by not flushing
    626   stdout when user code ends with an unterminated print. SF 695861
    627 
    628 - Moved responsibility for exception formatting (i.e. pruning IDLE internal
    629   calls) out of rpc.py into the client and server.
    630 
    631 - Exit IDLE cleanly even when doing subprocess I/O
    632 
    633 - Handle subprocess interrupt with an RPC message.
    634 
    635 - Restart the subprocess if it terminates itself. (VPython programs do that)
    636 
    637 - Support subclassing of exceptions, including in the shell, by moving the
    638   exception formatting to the subprocess.
    639 
    640 
    641 
    642 What's New in IDLEfork 0.9 Alpha 2?
    643 ===================================
    644 
    645 *Release date: 27-Jan-2003*
    646 
    647 - Updated INSTALL.txt to claify use of the python2 rpm.
    648 
    649 - Improved formatting in IDLE Help.
    650 
    651 - Run menu: Replace "Run Script" with "Run Module".
    652 
    653 - Code encountering an unhandled exception under the debugger now shows
    654   the correct traceback, with IDLE internal levels pruned out.
    655 
    656 - If an exception occurs entirely in IDLE, don't prune the IDLE internal
    657   modules from the traceback displayed.
    658 
    659 - Class Browser and Path Browser now use Alt-Key-2 for vertical zoom.
    660 
    661 - IDLE icons will now install correctly even when setup.py is run from the
    662   build directory
    663 
    664 - Class Browser now compatible with Python2.3 version of pyclbr.py
    665 
    666 - Left cursor move in presence of selected text now moves from left end
    667   of the selection.
    668 
    669 - Add Meta keybindings to "IDLE Classic Windows" to handle reversed
    670   Alt/Meta on some Linux distros.
    671 
    672 - Change default: IDLE now starts with Python Shell.
    673 
    674 - Removed the File Path from the Additional Help Sources scrolled list.
    675 
    676 - Add capability to access Additional Help Sources on the web if the
    677   Help File Path begins with //http or www.  (Otherwise local path is
    678   validated, as before.)
    679 
    680 - Additional Help Sources were not being posted on the Help menu in the
    681   order entered.  Implement sorting the list by [HelpFiles] 'option'
    682   number.
    683 
    684 - Add Browse button to New Help Source dialog.  Arrange to start in
    685   Python/Doc if platform is Windows, otherwise start in current directory.
    686 
    687 - Put the Additional Help Sources directly on the Help menu instead of in
    688   an Extra Help cascade menu.  Rearrange the Help menu so the Additional
    689   Help Sources come last.  Update help.txt appropriately.
    690 
    691 - Fix Tk root pop-ups in configSectionNameDialog.py  and configDialog.py
    692 
    693 - Uniform capitalization in General tab of ConfigDialog, update the doc string.
    694 
    695 - Fix bug in ConfigDialog where SaveAllChangedConfig() was unexpectedly
    696   deleting Additional Help Sources from the user's config file.
    697 
    698 - Make configHelpSourceEdit OK button the default and bind <Return>
    699 
    700 - Fix Tk root pop-ups in configHelpSourceEdit: error dialogs not attached
    701   to parents.
    702 
    703 - Use os.startfile() to open both Additional Help and Python Help on the
    704   Windows platform.  The application associated with the file type will act as
    705   the viewer.  Windows help files (.chm) are now supported via the
    706   Settings/General/Additional Help facility.
    707 
    708 - If Python Help files are installed locally on Linux, use them instead of
    709   accessing python.org.
    710 
    711 - Make the methods for finding the Python help docs more robust, and make
    712   them work in the installed configuration, also.
    713 
    714 - On the Save Before Run dialog, make the OK button the default.  One
    715   less mouse action!
    716 
    717 - Add a method: EditorWindow.get_geometry() for future use in implementing
    718   window location persistence.
    719 
    720 - Removed the "Help/Advice" menu entry.  Thanks, David!  We'll remember!
    721 
    722 - Change the "Classic Windows" theme's paste key to be <ctrl-v>.
    723 
    724 - Rearrange the Shell menu to put Stack Viewer entries adjacent.
    725 
    726 - Add the ability to restart the subprocess interpreter from the shell window;
    727   add an associated menu entry "Shell/Restart" with binding Control-F6.  Update
    728   IDLE help.
    729 
    730 - Upon a restart, annotate the shell window with a "restart boundary".  Add a
    731   shell window menu "Shell/View Restart" with binding F6 to jump to the most
    732   recent restart boundary.
    733 
    734 - Add Shell menu to Python Shell; change "Settings" to "Options".
    735 
    736 - Remove incorrect comment in setup.py: IDLEfork is now installed as a package.
    737 
    738 - Add INSTALL.txt, HISTORY.txt, NEWS.txt to installed configuration.
    739 
    740 - In installer text, fix reference to Visual Python, should be VPython.
    741   Properly credit David Scherer.
    742 
    743 - Modified idle, idle.py, idle.pyw to improve exception handling.
    744 
    745 
    746 What's New in IDLEfork 0.9 Alpha 1?
    747 ===================================
    748 
    749 *Release date: 31-Dec-2002*
    750 
    751 - First release of major new functionality.  For further details refer to
    752   Idle-dev and/or the Sourceforge CVS.
    753 
    754 - Adapted to the Mac platform.
    755 
    756 - Overhauled the IDLE startup options and revised the idle -h help message,
    757   which provides details of command line usage.
    758 
    759 - Multiple bug fixes and usability enhancements.
    760 
    761 - Introduced the new RPC implementation, which includes a debugger.  The output
    762   of user code is to the shell, and the shell may be used to inspect the
    763   environment after the run has finished.  (In version 0.8.1 the shell
    764   environment was separate from the environment of the user code.)
    765 
    766 - Introduced the configuration GUI and a new About dialog.
    767 
    768 - Removed David Scherer's Remote Procedure Call code and replaced with Guido
    769   van Rossum's.  GvR code has support for the IDLE debugger and uses the shell
    770   to inspect the environment of code Run from an Edit window.  Files removed:
    771   ExecBinding.py, loader.py, protocol.py, Remote.py, spawn.py
    772
