# Magic word to reject .pyc files generated by other Python versions.
# It should change for each incompatible change to the bytecode.
#
# The value of CR and LF is incorporated so if you ever read or write
# a .pyc file in text mode the magic number will be wrong; also, the
# Apple MPW compiler swaps their values, botching string constants.
#
# There were a variety of old schemes for setting the magic number.
# The current working scheme is to increment the previous value by
# 10.
#
# Starting with the adoption of PEP 3147 in Python 3.2, every bump in magic
# number also includes a new "magic tag", i.e. a human readable string used
# to represent the magic number in __pycache__ directories. When you change
# the magic number, you must also set a new unique magic tag. Generally this
# can be named after the Python major version of the magic number bump, but
# it can really be anything, as long as it's different than anything else
# that's come before. The tags are included in the following table, starting
# with Python 3.2a0.

A module's spec is the source for information about the module. For

loader.
`name` is the absolute name of the module. `loader` is the loader
to use when loading the module. `parent` is the name of the
package the module is in. The parent is derived from the name.
`is_package` determines if the module is considered a package or
not. On modules this is reflected by the `__path__` attribute.
`origin` is the specific location used by the loader from which to
load the module, if that information is available. When filename is
set, origin will match.
`has_location` indicates that a spec's "origin" reflects a location.
When this is True, `__file__` attribute of the module is set.
`cached` is the location of the cached bytecode file, if any. It
corresponds to the `__cached__` attribute.
`submodule_search_locations` is the sequence of path entries to
search when importing submodules. If set, is_package should be
True--and False otherwise.
Packages are simply modules that (may) have submodules. If a spec
has a non-None value in `submodule_search_locations`, the import
system will consider modules loaded from the spec as packages.
Only finders (see importlib.abc.MetaPathFinder and
importlib.abc.PathEntryFinder) should modify ModuleSpec instances.

This tests the '_objects' attribute of ctypes instances. '_objects'
holds references to objects that must be kept alive as long as the
ctypes instance, to make sure that the memory buffer is valid.
WARNING: The '_objects' attribute is exposed ONLY for debugging ctypes itself,
it MUST NEVER BE MODIFIED!
'_objects' is initialized to a dictionary on first use, before that it
is None.
Here is an array of string pointers:
>>> from ctypes import *
>>> array = (c_char_p * 5)()
>>> print(array._objects)
None
>>>
The memory block stores pointers to strings, and the strings itself
assigned from Python must be kept.
>>> array[4] = b'foo bar'
>>> array._objects
{'4': b'foo bar'}
>>> array[4]
b'foo bar'
>>>
It gets more complicated when the ctypes instance itself is contained
in a 'base' object.
>>> class X(Structure):
... _fields_ = [("x", c_int), ("y", c_int), ("array", c_char_p * 5)]
...
>>> x = X()
>>> print(x._objects)
None
>>>
The'array' attribute of the 'x' object shares part of the memory buffer
of 'x' ('_b_base_' is either None, or the root object owning the memory block):
>>> print(x.array._b_base_) # doctest: +ELLIPSIS

#
# Consider this call:
# func.restype = c_char_p
# func(c_char_p("123"))
# It returns

#
# WHY IS THIS SO?
#
# argument tuple (c_char_p("123"), ) is destroyed after the function
# func is called, but NOT before the result is actually built.
#
# If the arglist would be destroyed BEFORE the result has been built,
# the c_char_p("123") object would already have a zero refcount,
# and the pointer passed to (and returned by) the function would
# probably point to deallocated space.

cosmopolitan/third_party/python/Lib/idlelib/HISTORY.txt | 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 <[email protected]>
- 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.

IDLE MENUS
Top level items and most submenu items are defined in mainmenu.
Extenstions 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.

CODE STYLE -- Generally PEP 8.
import
------
Put import 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.

cosmopolitan/third_party/python/Lib/idlelib/NEWS2x.txt | What's New in IDLE 2.7? (Merged into 3.1 before 2.7 release.)
=======================
*Release date: XX-XXX-2010*
- idle.py modified and simplified to better support developing experimental
versions of IDLE which are not installed in the standard location.
- OutputWindow/PyShell right click menu "Go to file/line" wasn't working with
file paths containing spaces. Bug 5559.
- Windows: Version string for the .chm help file changed, file not being
accessed Patch 5783 Guilherme Polo
- 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.
- Issue #4455: IDLE failed to display the windows list when two windows have
the same title.
- Issue #4383: When IDLE cannot make the connection to its subprocess, it would
fail to properly display the error message.
- help() was not paging to the shell. Issue1650.
- CodeContext was not importing.
- Corrected two 3.0 compatibility errors reported by Mark Summerfield:
http://mail.python.org/pipermail/python-3000/2007-December/011491.html
- Shell was not colorizing due to bug introduced at r57998, Bug 1586.
- Issue #1585: IDLE uses non-existent xrange() function.
- Windows EOL sequence not converted correctly, encoding error.
Caused file save to fail. Bug 1130.
- IDLE converted to Python 3000 syntax.
- Strings became Unicode.
- CallTips module now uses the inspect module to produce the argspec.
- IDLE modules now use absolute import instead of implied relative import.
- atexit call replaces sys.exitfunc. The functionality of delete-exitfunc flag
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
would not start if a custom theme was defined.
- Home / Control-A toggles between left margin and end of leading white
space. issue1196903, patch by Jeff Shute.
- Improved AutoCompleteWindow logic. issue2062, patch by Tal Einat.
- Autocompletion of filenames now support alternate separators, e.g. the
'/' char on Windows. issue2061 Patch by Tal Einat.
- Configured selection highlighting colors were ignored; updating highlighting
in the config dialog would cause non-Python files to be colored as if they
were Python source; improve use of ColorDelagator. Patch 1334. Tal Einat.
- ScriptBinding event handlers weren't returning 'break'. Patch 2050, Tal Einat
- There was an error on exit if no sys.exitfunc was defined. Issue 1647.
- Could not open files in .idlerc directory if latter was hidden on Windows.
Issue 1743, Issue 1862.
- Configure Dialog: improved layout for keybinding. Patch 1457 Tal Einat.
- tabpage.py updated: tabbedPages.py now supports multiple dynamic rows
of tabs. Patch 1612746 Tal Einat.
- Add confirmation dialog before printing. Patch 1717170 Tal Einat.
- Show paste position if > 80 col. Patch 1659326 Tal Einat.

- OSX: Avoid crash for those versions of Tcl/Tk which don't have a console
- Bug in idlelib.MultiCall: Options dialog was crashing IDLE if there was an
option in config-extensions w/o a value. Patch #1672481, Tal Einat
- Corrected some bugs in AutoComplete. Also, Page Up/Down in ACW implemented;
mouse and cursor selection in ACWindow implemented; double Tab inserts
current selection and closes ACW (similar to double-click and Return); scroll
wheel now works in ACW. Added AutoComplete instructions to IDLE Help.
- AutoCompleteWindow moved below input line, will move above if there
isn't enough space. Patch 1621265 Tal Einat
- Calltips now 'handle' tuples in the argument list (display '<tuple>' :)
Suggested solution by Christos Georgiou, Bug 791968.
- Add 'raw' support to configHandler. Patch 1650174 Tal Einat.
- Avoid hang when encountering a duplicate in a completion list. Bug 1571112.
- Patch #1362975: Rework CodeContext indentation algorithm to
avoid hard-coding pixel widths.
- Bug #813342: Start the IDLE subprocess with -Qnew if the parent
is started with that option.
- Honor the "Cancel" action in the save dialog (Debian bug #299092)
- Some syntax errors were being caught by tokenize during the tabnanny
check, resulting in obscure error messages. Do the syntax check
first. Bug 1562716, 1562719
- IDLE's version number takes a big jump to match the version number of
the Python release of which it's a part.
What's New in IDLE 1.2?
=======================
*Release date: 19-SEP-2006*
- File menu hotkeys: there were three 'p' assignments. Reassign the
'Save Copy As' and 'Print' hotkeys to 'y' and 't'. Change the
Shell hotkey from 's' to 'l'.
- IDLE honors new quit() and exit() commands from site.py Quitter() object.
Patch 1540892, Jim Jewett
- The 'with' statement is now a Code Context block opener.
Patch 1540851, Jim Jewett
- Retrieval of previous shell command was not always preserving indentation
(since 1.2a1) Patch 1528468 Tal Einat.
- Changing tokenize (39046) to detect dedent broke tabnanny check (since 1.2a1)
- ToggleTab dialog was setting indent to 8 even if cancelled (since 1.2a1).
- When used w/o subprocess, all exceptions were preceded by an error
message claiming they were IDLE internal errors (since 1.2a1).
- Bug #1525817: Don't truncate short lines in IDLE's tool tips.
- Bug #1517990: IDLE keybindings on MacOS X now work correctly
- Bug #1517996: IDLE now longer shows the default Tk menu when a
path browser, class browser or debugger is the frontmost window on MacOS X
- EditorWindow.test() was failing. Bug 1417598
- EditorWindow failed when used stand-alone if sys.ps1 not set.
Bug 1010370 Dave Florek
- Tooltips failed on new-syle class __init__ args. Bug 1027566 Loren Guthrie
- Avoid occasional failure to detect closing paren properly.
Patch 1407280 Tal Einat
- Rebinding Tab key was inserting 'tab' instead of 'Tab'. Bug 1179168.
- Colorizer now handles #<builtin> correctly, also unicode strings and
'as' keyword in comment directly following import command. Closes 1325071.
Patch 1479219 Tal Einat
- Patch #1162825: Support non-ASCII characters in IDLE window titles.
- Source file f.flush() after writing; trying to avoid lossage if user
kills GUI.
- Options / Keys / Advanced dialog made functional. Also, allow binding
of 'movement' keys.
- '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

# below. So our stack looks something like this:
# outer main event loop
# run()
# <running program with traces>
# callback to debugger's interaction()
# nested event loop
# run() for second command
#
# This kind of nesting of event loops causes all kinds of problems

# subprocess, where there's all kinds of extra stuff happening in
# there - insert a traceback.print_stack() to check it out.
#
# By this point, we've already called restart_subprocess() in
# ScriptBinding. However, we also need to unwind the stack back to
# that outer event loop. To accomplish this, we:
# - return immediately from the nested run()
# - abort_loop ensures the nested event loop will terminate
# - the debugger's interaction routine completes normally
# - the restart_subprocess() will have taken care of stopping

<p>IDLE is Pythonâs Integrated Development and Learning Environment.</p>
<p>IDLE has the following features:</p>
<ul class="simple">
<li>coded in 100% pure Python, using the <a class="reference internal" href="tkinter.html#module-tkinter" title="tkinter: Interface to Tcl/Tk for graphical user interfaces"><code class="xref py py-mod docutils literal notranslate"><span class="pre">tkinter</span></code></a> GUI toolkit</li>
<li>cross-platform: works mostly the same on Windows, Unix, and macOS</li>
<li>Python shell window (interactive interpreter) with colorizing
of code input, output, and error messages</li>
<li>multi-window text editor with multiple undo, Python colorizing,
smart indent, call tips, auto completion, and other features</li>
<li>search within any window, replace within editor windows, and search
through multiple files (grep)</li>
<li>debugger with persistent breakpoints, stepping, and viewing
of global and local namespaces</li>
<li>configuration, browsers, and other dialogs</li>

<h2>Menus<a class="headerlink" href="#menus" title="Permalink to this headline">¶</a></h2>
<p>IDLE has two main window types, the Shell window and the Editor window. It is
possible to have multiple editor windows simultaneously. On Windows and
Linux, each has its own top menu. Each menu documented below indicates
which window type it is associated with.</p>
<p>Output windows, such as used for Edit => Find in Files, are a subtype of editor
window. They currently have the same top menu but a different
default title and context menu.</p>
<p>On macOS, there is one application menu. It dynamically changes according
to the window currently selected. It has an IDLE menu, and some entries
described below are moved around to conform to Apple guidlines.</p>

the next line is dedented. In leading indentation, <kbd class="kbd docutils literal notranslate">Backspace</kbd> deletes up
to 4 spaces if they are there. <kbd class="kbd docutils literal notranslate">Tab</kbd> inserts spaces (in the Python

are restricted to four spaces due to Tcl/Tk limitations.</p>
<p>See also the indent/dedent region commands in the edit menu.</p>
</div>
<div class="section" id="completions">
<h3>Completions<a class="headerlink" href="#completions" title="Permalink to this headline">¶</a></h3>
<p>Completions are supplied for functions, classes, and attributes of classes,
both built-in and user-defined. Completions are also provided for
filenames.</p>
<p>The AutoCompleteWindow (ACW) will open after a predefined delay (default is
two seconds) after a â.â or (in a string) an os.sep is typed. If after one
of those characters (plus zero or more other characters) a tab is typed
the ACW will open immediately if a possible continuation is found.</p>
<p>If there is only one possible completion for the characters entered, a
<kbd class="kbd docutils literal notranslate">Tab</kbd> will supply that completion without opening the ACW.</p>
<p>âShow Completionsâ will force open a completions window, by default the
<kbd class="kbd docutils literal notranslate">C-space</kbd> will open a completions window. In an empty
string, this will contain the files in the current directory. On a
blank line, it will contain the built-in and user-defined functions and
classes in the current namespaces, plus any modules imported. If some
characters have been entered, the ACW will attempt to be more specific.</p>
<p>If a string of characters is typed, the ACW selection will jump to the
entry most closely matching those characters. Entering a <kbd class="kbd docutils literal notranslate">tab</kbd> will
cause the longest non-ambiguous match to be entered in the Editor window or
Shell. Two <kbd class="kbd docutils literal notranslate">tab</kbd> in a row will supply the current ACW selection, as
will return or a double click. Cursor keys, Page Up/Down, mouse selection,
and the scroll wheel all operate on the ACW.</p>
<p>âHiddenâ attributes can be accessed by typing the beginning of hidden
name after a â.â, e.g. â_â. This allows access to modules with
<code class="docutils literal notranslate"><span class="pre">__all__</span></code> set, or to class-private attributes.</p>
<p>Completions and the âExpand Wordâ facility can save a lot of typing!</p>
<p>Completions are currently limited to those in the namespaces. Names in
an Editor window which are not via <code class="docutils literal notranslate"><span class="pre">__main__</span></code> and <a class="reference internal" href="sys.html#sys.modules" title="sys.modules"><code class="xref py py-data docutils literal notranslate"><span class="pre">sys.modules</span></code></a> will
not be found. Run the module once with your imports to correct this situation.
Note that IDLE itself places quite a few modules in sys.modules, so
much can be found by default, e.g. the re module.</p>
<p>If you donât like the ACW popping up unbidden, simply make the delay
longer or disable the extension.</p>
</div>
<div class="section" id="calltips">
<h3>Calltips<a class="headerlink" href="#calltips" title="Permalink to this headline">¶</a></h3>
<p>A calltip is shown when one types <kbd class="kbd docutils literal notranslate">(</kbd> after the name of an <em>accessible</em>
function. A name expression may include dots and subscripts. A calltip
remains until it is clicked, the cursor is moved out of the argument area,
or <kbd class="kbd docutils literal notranslate">)</kbd> is typed. When the cursor is in the argument part of a definition,
the menu or shortcut display a calltip.</p>
<p>A calltip consists of the function signature and the first line of the
docstring. For builtins without an accessible signature, the calltip
consists of all lines up the fifth line or the first blank line. These
details may change.</p>
<p>The set of <em>accessible</em> functions depends on what modules have been imported
into the user process, including those imported by Idle itself,
and what definitions have been run, all since the last restart.</p>
<p>For example, restart the Shell and enter <code class="docutils literal notranslate"><span class="pre">itertools.count(</span></code>. A calltip
appears because Idle imports itertools into the user process for its own use.
(This could change.) Enter <code class="docutils literal notranslate"><span class="pre">turtle.write(</span></code> and nothing appears. Idle does
not import turtle. The menu or shortcut do nothing either. Enter
<code class="docutils literal notranslate"><span class="pre">import</span> <span class="pre">turtle</span></code> and then <code class="docutils literal notranslate"><span class="pre">turtle.write(</span></code> will work.</p>
<p>In an editor, import statements have no effect until one runs the file. One
might want to run a file after writing the import statements at the top,
or immediately run an existing file before editing.</p>

<div class="section" id="python-shell-window">
<h3>Python Shell window<a class="headerlink" href="#python-shell-window" title="Permalink to this headline">¶</a></h3>

Most consoles and terminals only work with a single physical line at a time.</p>
<p>When one pastes code into Shell, it is not compiled and possibly executed
until one hits <kbd class="kbd docutils literal notranslate">Return</kbd>. One may edit pasted code first.
If one pastes more that one statement into Shell, the result will be a

<div class="section" id="text-colors">
<h3>Text colors<a class="headerlink" href="#text-colors" title="Permalink to this headline">¶</a></h3>
<p>Idle defaults to black on white text, but colors text with special meanings.
For the shell, these are shell output, shell error, user output, and
user error. For Python code, at the shell prompt or in an editor, these are
keywords, builtin class and function names, names following <code class="docutils literal notranslate"><span class="pre">class</span></code> and
<code class="docutils literal notranslate"><span class="pre">def</span></code>, strings, and comments. For any text window, these are the cursor (when
present), found text (when possible), and selected text.</p>
<p>Text coloring is done in the background, so uncolorized text is occasionally
visible. To change the color scheme, use the Configure IDLE dialog
Highlighting tab. The marking of debugger breakpoint lines in the editor and
text in popups and dialogs is not user-configurable.</p>

the environment variables <span class="target" id="index-5"></span><code class="xref std std-envvar docutils literal notranslate"><span class="pre">IDLESTARTUP</span></code> or <span class="target" id="index-6"></span><a class="reference internal" href="../using/cmdline.html#envvar-PYTHONSTARTUP"><code class="xref std std-envvar docutils literal notranslate"><span class="pre">PYTHONSTARTUP</span></code></a>.
IDLE first checks for <code class="docutils literal notranslate"><span class="pre">IDLESTARTUP</span></code>; if <code class="docutils literal notranslate"><span class="pre">IDLESTARTUP</span></code> is present the file

<code class="docutils literal notranslate"><span class="pre">PYTHONSTARTUP</span></code>. Files referenced by these environment variables are
convenient places to store functions that are used frequently from the IDLE
shell, or for executing import statements to import common modules.</p>
<p>In addition, <code class="docutils literal notranslate"><span class="pre">Tk</span></code> also loads a startup file if it is present. Note that the
Tk file is loaded unconditionally. This additional file is <code class="docutils literal notranslate"><span class="pre">.Idle.py</span></code> and is

<div class="section" id="startup-failure">
<h3>Startup failure<a class="headerlink" href="#startup-failure" title="Permalink to this headline">¶</a></h3>
<p>IDLE uses a socket to communicate between the IDLE GUI process and the user
code execution process. A connection must be established whenever the Shell
starts or restarts. (The latter is indicated by a divider line that says
âRESTARTâ). If the user process fails to connect to the GUI process, it
displays a <code class="docutils literal notranslate"><span class="pre">Tk</span></code> error box with a âcannot connectâ message that directs the
user here. It then exits.</p>
<p>A common cause of failure is a user-written file with the same name as a
standard library module, such as <em>random.py</em> and <em>tkinter.py</em>. When such a
file is located in the same directory as a file that is about to be run,
IDLE cannot import the stdlib file. The current fix is to rename the
user file.</p>
<p>Though less common than in the past, an antivirus or firewall program may
stop the connection. If the program cannot be taught to allow the
connection, then it must be turned off for IDLE to work. It is safe to
allow this internal connection because no data is visible on external
ports. A similar problem is a network mis-configuration that blocks
connections.</p>
<p>Python installation issues occasionally stop IDLE: multiple versions can
clash, or a single installation might need admin access. If one undo the
clash, or cannot or does not want to run as admin, it might be easiest to
completely remove Python and start over.</p>
<p>A zombie pythonw.exe process could be a problem. On Windows, use Task
Manager to detect and stop one. Sometimes a restart initiated by a program
crash or Keyboard Interrupt (control-C) may fail to connect. Dismissing
the error box or Restart Shell on the Shell menu may fix a temporary problem.</p>
<p>When IDLE first starts, it attempts to read user configuration files in
~/.idlerc/ (~ is oneâs home directory). If there is a problem, an error
message should be displayed. Leaving aside random disk glitches, this can
be prevented by never editing the files by hand, using the configuration
dialog, under Options, instead Options. Once it happens, the solution may
be to delete one or more of the configuration files.</p>
<p>If IDLE quits with no message, and it was not started from a console, try
starting from a console (<code class="docutils literal notranslate"><span class="pre">python</span> <span class="pre">-m</span> <span class="pre">idlelib)</span></code> and see if a message appears.</p>
</div>
<div class="section" id="running-user-code">
<h3>Running user code<a class="headerlink" href="#running-user-code" title="Permalink to this headline">¶</a></h3>
<p>With rare exceptions, the result of executing Python code with IDLE is
intended to be the same as executing the same code by the default method,
directly with Python in a text-mode system console or terminal window.
However, the different interface and operation occasionally affect
visible results. For instance, <code class="docutils literal notranslate"><span class="pre">sys.modules</span></code> starts with more entries,
and <code class="docutils literal notranslate"><span class="pre">threading.activeCount()</span></code> returns 2 instead of 1.</p>
<p>By default, IDLE runs user code in a separate OS process rather than in
the user interface process that runs the shell and editor. In the execution
process, it replaces <code class="docutils literal notranslate"><span class="pre">sys.stdin</span></code>, <code class="docutils literal notranslate"><span class="pre">sys.stdout</span></code>, and <code class="docutils literal notranslate"><span class="pre">sys.stderr</span></code>
with objects that get input from and send output to the Shell window.
The original values stored in <code class="docutils literal notranslate"><span class="pre">sys.__stdin__</span></code>, <code class="docutils literal notranslate"><span class="pre">sys.__stdout__</span></code>, and
<code class="docutils literal notranslate"><span class="pre">sys.__stderr__</span></code> are not touched, but may be <code class="docutils literal notranslate"><span class="pre">None</span></code>.</p>
<p>When Shell has the focus, it controls the keyboard and screen. This is
normally transparent, but functions that directly access the keyboard
and screen will not work. These include system-specific functions that
determine whether a key has been pressed and if so, which.</p>
<p>IDLEâs standard stream replacements are not inherited by subprocesses
created in the execution process, whether directly by user code or by modules
such as multiprocessing. If such subprocess use <code class="docutils literal notranslate"><span class="pre">input</span></code> from sys.stdin
or <code class="docutils literal notranslate"><span class="pre">print</span></code> or <code class="docutils literal notranslate"><span class="pre">write</span></code> to sys.stdout or sys.stderr,
IDLE should be started in a command line window. The secondary subprocess
will then be attached to that window for input and output.</p>
<p>If <code class="docutils literal notranslate"><span class="pre">sys</span></code> is reset by user code, such as with <code class="docutils literal notranslate"><span class="pre">importlib.reload(sys)</span></code>,
IDLEâs changes are lost and input from the keyboard and output to the screen
will not work correctly.</p>
</div>
<div class="section" id="user-output-in-shell">
<h3>User output in Shell<a class="headerlink" href="#user-output-in-shell" title="Permalink to this headline">¶</a></h3>
<p>When a program outputs text, the result is determined by the
corresponding output device. When IDLE executes user code, <code class="docutils literal notranslate"><span class="pre">sys.stdout</span></code>
and <code class="docutils literal notranslate"><span class="pre">sys.stderr</span></code> are connected to the display area of IDLEâs Shell. Some of
its features are inherited from the underlying Tk Text widget. Others
are programmed additions. Where it matters, Shell is designed for development
rather than production runs.</p>
<p>For instance, Shell never throws away output. A program that sends unlimited
output to Shell will eventually fill memory, resulting in a memory error.
In contrast, some system text windows only keep the last n lines of output.
A Windows console, for instance, keeps a user-settable 1 to 9999 lines,
with 300 the default.</p>
<p>Text widgets display a subset of Unicode, the Basic Multilingual Plane (BMP).
Which characters get a proper glyph instead of a replacement box depends on
the operating system and installed fonts. Newline characters cause following
text to appear on a new line, but other control characters are either
replaced with a box or deleted. However, <code class="docutils literal notranslate"><span class="pre">repr()</span></code>, which is used for
interactive echo of expression values, replaces control characters,
some BMP codepoints, and all non-BMP characters with escape codes
before they are output.</p>
<p>Normal and error output are generally kept separate (on separate lines)
from code input and each other. They each get different highlight colors.</p>
<p>For SyntaxError tracebacks, the normal â^â marking where the error was
detected is replaced by coloring the text with an error highlight.
When code run from a file causes other exceptions, one may right click
on a traceback line to jump to the corresponding line in an IDLE editor.
The file will be opened if necessary.</p>
<p>Shell has a special facility for squeezing output lines down to a
âSqueezed textâ label. This is done automatically
for output over N lines (N = 50 by default).
N can be changed in the PyShell section of the General
page of the Settings dialog. Output with fewer lines can be squeezed by
right clicking on the output. This can be useful lines long enough to slow
down scrolling.</p>
<p>Squeezed output is expanded in place by double-clicking the label.
It can also be sent to the clipboard or a separate view window by
right-clicking the label.</p>

<h3>Developing tkinter applications<a class="headerlink" href="#developing-tkinter-applications" title="Permalink to this headline">¶</a></h3>
<p>IDLE is intentionally different from standard Python in order to
facilitate development of tkinter programs. Enter <code class="docutils literal notranslate"><span class="pre">import</span> <span class="pre">tkinter</span> <span class="pre">as</span> <span class="pre">tk;</span>
<span class="pre">root</span> <span class="pre">=</span> <span class="pre">tk.Tk()</span></code> in standard Python and nothing appears. Enter the same
in IDLE and a tk window appears. In standard Python, one must also enter
<code class="docutils literal notranslate"><span class="pre">root.update()</span></code> to see the window. IDLE does the equivalent in the
background, about 20 times a second, which is about every 50 milleseconds.
Next enter <code class="docutils literal notranslate"><span class="pre">b</span> <span class="pre">=</span> <span class="pre">tk.Button(root,</span> <span class="pre">text='button');</span> <span class="pre">b.pack()</span></code>. Again,
nothing visibly changes in standard Python until one enters <code class="docutils literal notranslate"><span class="pre">root.update()</span></code>.</p>
<p>Most tkinter programs run <code class="docutils literal notranslate"><span class="pre">root.mainloop()</span></code>, which usually does not
return until the tk app is destroyed. If the program is run with
<code class="docutils literal notranslate"><span class="pre">python</span> <span class="pre">-i</span></code> or from an IDLE editor, a <code class="docutils literal notranslate"><span class="pre">>>></span></code> shell prompt does not
appear until <code class="docutils literal notranslate"><span class="pre">mainloop()</span></code> returns, at which time there is nothing left
to interact with.</p>
<p>When running a tkinter program from an IDLE editor, one can comment out
the mainloop call. One then gets a shell prompt immediately and can
interact with the live application. One just has to remember to
re-enable the mainloop call when running in standard Python.</p>
</div>
<div class="section" id="running-without-a-subprocess">
<h3>Running without a subprocess<a class="headerlink" href="#running-without-a-subprocess" title="Permalink to this headline">¶</a></h3>
<p>By default, IDLE executes user code in a separate subprocess via a socket,
which uses the internal loopback interface. This connection is not
externally visible and no data is sent to or received from the Internet.
If firewall software complains anyway, you can ignore it.</p>
<p>If the attempt to make the socket connection fails, Idle will notify you.
Such failures are sometimes transient, but if persistent, the problem
may be either a firewall blocking the connection or misconfiguration of
a particular system. Until the problem is fixed, one can run Idle with
the -n command line switch.</p>
<p>If IDLE is started with the -n command line switch it will run in a
single process and will not create the subprocess which runs the RPC
Python execution server. This can be useful if Python cannot create
the subprocess or the RPC socket interface on your platform. However,
in this mode user code is not isolated from IDLE itself. Also, the
environment is not restarted when Run/Run Module (F5) is selected. If
your code has been modified, you must reload() the affected modules and
re-import any specific items (e.g. from foo import baz) if the changes
are to take effect. For these reasons, it is preferable to run IDLE
with the default subprocess if at all possible.</p>

<h3>Help sources<a class="headerlink" href="#help-sources" title="Permalink to this headline">¶</a></h3>
<p>Help menu entry âIDLE Helpâ displays a formatted html version of the
IDLE chapter of the Library Reference. The result, in a read-only
tkinter text window, is close to what one sees in a web browser.
Navigate through the text with a mousewheel,
the scrollbar, or up and down arrow keys held down.
Or click the TOC (Table of Contents) button and select a section
header in the opened box.</p>
<p>Help menu entry âPython Docsâ opens the extensive sources of help,
including tutorials, available at docs.python.org/x.y, where âx.yâ
is the currently running Python version. If your system
has an off-line copy of the docs (this may be an installation option),
that will be opened instead.</p>

<h3>Setting preferences<a class="headerlink" href="#setting-preferences" title="Permalink to this headline">¶</a></h3>
<p>The font preferences, highlighting, keys, and general preferences can be
changed via Configure IDLE on the Option menu. Keys can be user defined;
IDLE ships with four built-in key sets. In addition, a user can create a
custom key set in the Configure IDLE dialog under the keys tab.</p>

<h3>IDLE on macOS<a class="headerlink" href="#idle-on-macos" title="Permalink to this headline">¶</a></h3>
<p>Under System Preferences: Dock, one can set âPrefer tabs when opening
documentsâ to âAlwaysâ. This setting is not compatible with the tk/tkinter
GUI framework used by IDLE, and it breaks a few IDLE features.</p>
</div>
<div class="section" id="extensions">
<h3>Extensions<a class="headerlink" href="#extensions" title="Permalink to this headline">¶</a></h3>
<p>IDLE contains an extension facility. Preferences for extensions can be
changed with the Extensions tab of the preferences dialog. See the
beginning of config-extensions.def in the idlelib directory for further
information. The only current default extension is zzdummy, an example
also used for testing.</p>

cosmopolitan/third_party/python/Lib/idlelib/extend.txt | 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-extensions.def. See below for details.
An IDLE extension is defined by a class. Methods of the class define
actions that are invoked by event 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 guaranteed 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 directly bind Window Manager (e.g. X) events.
Rather, it must define one or more virtual events, e.g. <<zoom-height>>, and
corresponding methods, e.g. zoom_height_event(). The virtual events will be
bound to the corresponding methods, and Window Manager events can then be bound
to the virtual events. (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.)
An extension can define menu entries. This is done with a class or instance
variable named menudefs; it should be a list of pairs, 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 key bindings are still applied. (This
should probably be refined in the future.)
Extensions are not required to define menu entries for all the events they
implement. (They are also not required to create keybindings, but in that
case there must be empty bindings in cofig-extensions.def)
Here is a complete example:
class ZoomHeight:
menudefs = [
('edit', [
None, # Separator
('_Zoom Height', '<<zoom-height>>'),
])
]
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-extensions.def", which is
used to configure the loading of extensions and to establish key (or, more
generally, event) bindings to the virtual events defined in the extensions.
See the comments at the top of config-extensions.def for information. It's
currently necessary to manually modify that file to change IDLE's extension
loading or extension key bindings.
For further information on binding refer to the Tkinter Resources web page at
python.org and to the Tk Command "bind" man page.

cosmopolitan/third_party/python/Lib/idlelib/TODO.txt | 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

cosmopolitan/third_party/python/Lib/idlelib/config-keys.def | # IDLE reads several config files to determine user preferences. This
# file is the default config file for idle key binding settings.
