cosmopolitan/third_party/python/Lib/idlelib/config-main.def | # IDLE reads several config files to determine user preferences. This
# file is the default config file for general idle settings.
#
# When IDLE starts, it will look in
# the following two sets of files, in order:
#
# default configuration files in idlelib
# --------------------------------------
# config-main.def default general config file
# config-extensions.def default extension config file
# config-highlight.def default highlighting config file
# config-keys.def default keybinding config file
#
# user configuration files in ~/.idlerc
# -------------------------------------
# config-main.cfg user general config file
# config-extensions.cfg user extension config file
# config-highlight.cfg user highlighting config file
# config-keys.cfg user keybinding config file
#
# On Windows, the default location of the home directory ('~' above)
# depends on the version. For Windows 10, it is C:\Users\<username>.
#
# Any options the user saves through the config dialog will be saved to
# the relevant user config file. Reverting any general or extension
# setting to the default causes that entry to be wiped from the user
# file and re-read from the default file. This rule applies to each
# item, except that the three editor font items are saved as a group.
#
# User highlighting themes and keybinding sets must have (section) names
# distinct from the default names. All items are added and saved as a
# group. They are retained unless specifically deleted within the config
# dialog. Choosing one of the default themes or keysets just applies the
# relevant settings from the default file.
#
# Additional help sources are listed in the [HelpFiles] section below
# and should be viewable by a web browser (or the Windows Help viewer in
# the case of .chm files). These sources will be listed on the Help
# menu. The pattern, and two examples, are
#
# <sequence_number = menu item;/path/to/help/source>
# 1 = IDLE;C:/Programs/Python36/Lib/idlelib/help.html
# 2 = Pillow;https://pillow.readthedocs.io/en/latest/
#
# You can't use a semi-colon in a menu item or path. The path will be
# platform specific because of path separators, drive specs etc.
#
# The default files should not be edited except to add new sections to
# config-extensions.def for added extensions . The user files should be
# modified through the Settings dialog.

cosmopolitan/third_party/python/Lib/idlelib/NEWS.txt | What's New in IDLE 3.6.8
Released on 2018-12-20?
**This is the final 3.6 bugfix maintenance release**
======================================
bpo-34864: When starting IDLE on MacOS, warn if the system setting
"Prefer tabs when opening documents" is "Always". As previous
documented for this issue, running IDLE with this setting causes
problems. If the setting is changed while IDLE is running,
there will be no warning until IDLE is restarted.
bpo-35213: Where appropriate, use 'macOS' in idlelib.
bpo-34864: Document two IDLE on MacOS issues. The System Preferences
Dock "prefer tabs always" setting disables some IDLE features.
Menus are a bit different than as described for Windows and Linux.
bpo-35202: Remove unused imports in idlelib.
bpo-33000: Document that IDLE's shell has no line limit.
A program that runs indefinitely can overfill memory.
bpo-23220: Explain how IDLE's Shell displays output.
Add new subsection "User output in Shell".
bpo-35099: Improve the doc about IDLE running user code.
"IDLE -- console differences" is renamed "Running user code".
It mostly covers the implications of using custom sys.stdxxx objects.
bpo-35097: Add IDLE doc subsection explaining editor windows.
Topics include opening, title and status bars, .py* extension, and running.
Issue 35093: Document the IDLE document viewer in the IDLE doc.
Add a paragraph in "Help and preferences", "Help sources" subsection.
bpo-1529353: Explain Shell text squeezing in the IDLE doc.
bpo-35088: Update idlelib.help.copy_string docstring.
We now use git and backporting instead of hg and forward merging.
bpo-35087: Update idlelib help files for the current doc build.
The main change is the elimination of chapter-section numbers.
What's New in IDLE 3.6.7
Released on 2018-10-20
======================================
bpo-1529353: Output over N lines (50 by default) is squeezed down to a button.
N can be changed in the PyShell section of the General page of the
Settings dialog. Fewer, but possibly extra long, lines can be squeezed by
right clicking on the output. Squeezed output can be expanded in place
by double-clicking the button or into the clipboard or a separate window
by right-clicking the button.
bpo-34548: Use configured color theme for read-only text views.
bpo-33839: Refactor ToolTip and CallTip classes; add documentation
and tests.
bpo-34047: Fix mouse wheel scrolling direction on macOS.
bpo-34275: Make calltips always visible on Mac.
Patch by Kevin Walzer.
bpo-34120: Fix freezing after closing some dialogs on Mac.
This is one of multiple regressions from using newer tcl/tk.
bpo-33975: Avoid small type when running htests.
Since part of the purpose of human-viewed tests is to determine that
widgets look right, it is important that they look the same for
testing as when running IDLE.
bpo-33905: Add test for idlelib.stackview.StackBrowser.
bpo-33924: Change mainmenu.menudefs key 'windows' to 'window'.
Every other menudef key is the lowercase version of the
corresponding main menu entry (in this case, 'Window').
bpo-33906: Rename idlelib.windows as window
Match Window on the main menu and remove last plural module name.
Change imports, test, and attribute references to match new name.
bpo-33917: Fix and document idlelib/idle_test/template.py.
The revised file compiles, runs, and tests OK. idle_test/README.txt
explains how to use it to create new IDLE test files.
bpo-33904: In rstrip module, rename class RstripExtension as Rstrip.
bpo-33907: For consistency and clarity, rename calltip objects.
Module calltips and its class CallTips are now calltip and Calltip.
In module calltip_w, class CallTip is now CalltipWindow.
bpo-33855: Minimally test all IDLE modules.
Standardize the test file format. Add missing test files that import
the tested module and perform at least one test. Check and record the
coverage of each test.
bpo-33856: Add 'help' to Shell's initial welcome message.
What's New in IDLE 3.6.6
Released on 2018-06-27
======================================
bpo-33656: On Windows, add API call saying that tk scales for DPI.
On Windows 8.1+ or 10, with DPI compatibility properties of the Python
binary unchanged, and a monitor resolution greater than 96 DPI, this
should make text and lines sharper and some colors brighter.
On other systems, it should have no effect. If you have a custom theme,
you may want to adjust a color or two. If perchance it make text worse
on your monitor, you can disable the ctypes.OleDLL call near the top of
pyshell.py and report the problem on python-list or [email protected].
bpo-33768: Clicking on a context line moves that line to the top
of the editor window.
bpo-33763: Replace the code context label widget with a text widget.
bpo-33664: Scroll IDLE editor text by lines.
(Previously, the mouse wheel and scrollbar slider moved text by a fixed
number of pixels, resulting in partial lines at the top of the editor
box.) This change also applies to the shell and grep output windows,
but currently not to read-only text views.
bpo-33679: Enable theme-specific color configuration for Code Context.
(Previously, there was one code context foreground and background font
color setting, default or custom, on the extensions tab, that applied
to all themes.) For built-in themes, the foreground is the same as
normal text and the background is a contrasting gray. Context colors for
custom themes are set on the Hightlights tab along with other colors.
When one starts IDLE from a console and loads a custom theme without
definitions for 'context', one will see a warning message on the
console.
bpo-33642: Display up to maxlines non-blank lines for Code Context.
If there is no current context, show a single blank line. (Previously,
the Code Contex had numlines lines, usually with some blank.) The use
of a new option, 'maxlines' (default 15), avoids possible interference
with user settings of the old option, 'numlines' (default 3).
bpo-33628: Cleanup codecontext.py and its test.
bpo-32831: Add docstrings and tests for codecontext.py.
Coverage is 100%. Patch by Cheryl Sabella.
bpo-33564: Code context now recognizes async as a block opener.
bpo-29706: IDLE now colors async and await as keywords in 3.6.
They become full keywords in 3.7.
bpo-21474: Update word/identifier definition from ascii to unicode.
In text and entry boxes, this affects selection by double-click,
movement left/right by control-left/right, and deletion left/right
by control-BACKSPACE/DEL.
bpo-33204: Consistently color invalid string prefixes.
A 'u' string prefix cannot be paired with either 'r' or 'f'.
IDLE now consistently colors as much of the prefix, starting at the
right, as is valid. Revise and extend colorizer test.
What's New in IDLE 3.6.5
Released on 2018-03-28
======================================
bpo-32984: Set __file__ while running a startup file.
Like Python, IDLE optionally runs 1 startup file in the Shell window
before presenting the first interactive input prompt. For IDLE,
option -s runs a file named in environmental variable IDLESTARTUP or
PYTHONSTARTUP; -r file runs file. Python sets __file__ to the startup
file name before running the file and unsets it before the first
prompt. IDLE now does the same when run normally, without the -n
option.
bpo-32940: Replace StringTranslatePseudoMapping with faster code.
bpo-32916: Change 'str' to 'code' in idlelib.pyparse and users.
bpo-32905: Remove unused code in pyparse module.
bpo-32874: IDLE - add pyparse tests with 97% coverage.
bpo-32837: IDLE - require encoding argument for textview.view_file.
Using the system and place-dependent default encoding for open()
is a bad idea for IDLE's system and location-independent files.
bpo-32826: Add "encoding=utf-8" to open() in IDLE's test_help_about.
GUI test test_file_buttons() only looks at initial ascii-only lines,
but failed on systems where open() defaults to 'ascii' because
readline() internally reads and decodes far enough ahead to encounter
a non-ascii character in CREDITS.txt.
bpo-32765: Update configdialog General tab create page docstring.
Add new widgets to the widget list.
What's New in IDLE 3.6.4
Released on 2017-12-19
========================
bpo-32207: Improve tk event exception tracebacks in IDLE.
When tk event handling is driven by IDLE's run loop, a confusing
and distracting queue.EMPTY traceback context is no longer added
to tk event exception tracebacks. The traceback is now the same
as when event handling is driven by user code. Patch based on
a suggestion by Serhiy Storchaka.
bpo-32164: Delete unused file idlelib/tabbedpages.py.
Use of TabbedPageSet in configdialog was replaced by ttk.Notebook.
bpo-32100: Fix old and new bugs in pathbrowser; improve tests.
Patch mostly by Cheryl Sabella.
bpo-31860: The font sample in the settings dialog is now editable.
Edits persist while IDLE remains open.
Patch by Serhiy Storchake and Terry Jan Reedy.
bpo-31858: Restrict shell prompt manipulation to the shell.
Editor and output windows only see an empty last prompt line. This
simplifies the code and fixes a minor bug when newline is inserted.
Sys.ps1, if present, is read on Shell start-up, but is not set or changed.
Patch by Terry Jan Reedy.
bpo-28603: Fix a TypeError that caused a shell restart when printing
a traceback that includes an exception that is unhashable.
Patch by Zane Bitter.
bpo-13802: Use non-Latin characters in the Font settings sample.
Even if one selects a font that defines a limited subset of the unicode
Basic Multilingual Plane, tcl/tk will use other fonts that define a
character. The expanded example give users of non-Latin characters
a better idea of what they might see in the shell and editors.
To make room for the expanded sample, frames on the Font tab are
re-arranged. The Font/Tabs help explains a bit about the additions.
Patch by Terry Jan Reedy
What's New in IDLE 3.6.3
Released on 2017-10-03
========================
bpo-31460: Simplify the API of IDLE's Module Browser.
Passing a widget instead of an flist with a root widget opens the
option of creating a browser frame that is only part of a window.
Passing a full file name instead of pieces assumed to come from a
.py file opens the possibility of browsing python files that do not
end in .py.
bpo-31649: Make _htest and _utest parameters keyword-only.
These are used to adjust code for human and unit tests.
bpo-31459: Rename module browser from Class Browser to Module Browser.
The original module-level class and method browser became a module
browser, with the addition of module-level functions, years ago.
Nested classes and functions were added yesterday. For back-
compatibility, the virtual event <<open-class-browser>>, which
appears on the Keys tab of the Settings dialog, is not changed.
Patch by Cheryl Sabella.
bpo-1612262: Module browser now shows nested classes and functions.
Original patches for code and tests by Guilherme Polo and
Cheryl Sabella, respectively. Revisions by Terry Jan Reedy.
bpo-31500: Tk's default fonts now are scaled on HiDPI displays.
This affects all dialogs. Patch by Serhiy Storchaka.
bpo-31493: Fix code context update and font update timers.
Canceling timers prevents a warning message when test_idle completes.
bpo-31488: Update non-key options in former extension classes.
When applying configdialog changes, call .reload for each feature class.
Change ParenMatch so updated options affect existing instances attached
to existing editor windows.
bpo-31477: Improve rstrip entry in IDLE doc.
Strip Trailing Whitespace strips more than blank spaces.
Multiline string literals are not skipped.
bpo-31480: fix tests to pass with zzdummy extension disabled. (#3590)
To see the example in action, enable it on options extensions tab.
bpo-31421: Document how IDLE runs tkinter programs.
IDLE calls tcl/tk update in the background in order to make live
interaction and experimentation with tkinter applications much easier.
bpo-31414: Fix tk entry box tests by deleting first.
Adding to an int entry is not the same as deleting and inserting
because int('') will fail. Patch by Terry Jan Reedy.
bpo-27099: Convert IDLE's built-in 'extensions' to regular features.
About 10 IDLE features were implemented as supposedly optional
extensions. Their different behavior could be confusing or worse for
users and not good for maintenance. Hence the conversion.
The main difference for users is that user configurable key bindings
for builtin features are now handled uniformly. Now, editing a binding
in a keyset only affects its value in the keyset. All bindings are
defined together in the system-specific default keysets in config-
extensions.def. All custom keysets are saved as a whole in config-
extension.cfg. All take effect as soon as one clicks Apply or Ok.
The affected events are '<<force-open-completions>>',
'<<expand-word>>', '<<force-open-calltip>>', '<<flash-paren>>',
'<<format-paragraph>>', '<<run-module>>', '<<check-module>>', and
'<<zoom-height>>'. Any (global) customizations made before 3.6.3 will
not affect their keyset-specific customization after 3.6.3. and vice
versa.
Initial patch by Charles Wohlganger, revised by Terry Jan Reedy.
bpo-31051: Rearrange condigdialog General tab.
Sort non-Help options into Window (Shell+Editor) and Editor (only).
Leave room for the addition of new options.
Patch by Terry Jan Reedy.
bpo-30617: Add docstrings and tests for outwin subclass of editor.
Move some data and functions from the class to module level.
Patch by Cheryl Sabella.
bpo-31287: Do not modify tkinter.messagebox in test_configdialog.
Instead, mask it with an instance mock that can be deleted.
Patch by Terry Jan Reedy.
bpo-30781: Use ttk widgets in ConfigDialog pages.
These should especially look better on MacOSX.
Patches by Terry Jan Reedy and Cheryl Sabella.
bpo-31206: Factor HighPage(Frame) class from ConfigDialog.
Patch by Cheryl Sabella.
bp0-31001: Add tests for configdialog highlight tab.
Patch by Cheryl Sabella.
bpo-31205: Factor KeysPage(Frame) class from ConfigDialog.
The slightly modified tests continue to pass.
Patch by Cheryl Sabella.
bpo-31002: Add tests for configdialog keys tab.
Patch by Cheryl Sabella.
bpo-19903: Change calltipes to use inspect.signature.
Idlelib.calltips.get_argspec now uses inspect.signature instead of
inspect.getfullargspec, like help() does. This improves the signature
in the call tip in a few different cases, including builtins converted
to provide a signature. A message is added if the object is not
callable, has an invalid signature, or if it has positional-only
parameters. Patch by Louie Lu.
bop-31083: Add an outline of a TabPage class in configdialog.
Add template as comment. Update existing classes to match outline.
Initial patch by Cheryl Sabella.
bpo-31050: Factor GenPage(Frame) class from ConfigDialog.
The slightly modified tests for the General tab continue to pass.
Patch by Cheryl Sabella.
bpo-31004: Factor FontPage(Frame) class from ConfigDialog.
The slightly modified tests continue to pass. The General test
broken by the switch to ttk.Notebook is fixed.
Patch mostly by Cheryl Sabella.
bpo-30781: IDLE - Use ttk Notebook in ConfigDialog.
This improves navigation by tabbing.
Patch by Terry Jan Reedy.
bpo-31060: IDLE - Finish rearranging methods of ConfigDialog.
Grouping methods pertaining to each tab and the buttons will aid
writing tests and improving the tabs and will enable splitting the
groups into classes.
Patch by Terry Jan Reedy.
bpo-30853: IDLE -- Factor a VarTrace class out of ConfigDialog.
Instance tracers manages pairs consisting of a tk variable and a
callback function. When tracing is turned on, setting the variable
calls the function. Test coverage for the new class is 100%.
Patch by Terry Jan Reedy.
bpo-31003: IDLE: Add more tests for General tab.
Patch by Terry Jan Reedy.
bpo-30993: IDLE - Improve configdialog font page and tests.
*In configdialog: Document causal pathways in create_font_tab
docstring. Simplify some attribute names. Move set_samples calls to
var_changed_font (idea from Cheryl Sabella). Move related functions to
positions after the create widgets function.
* In test_configdialog: Fix test_font_set so not order dependent. Fix
renamed test_indent_scale so it tests the widget. Adjust tests for
movement of set_samples call. Add tests for load functions. Put all
font tests in one class and tab indent tests in another. Except for
two lines, these tests completely cover the related functions.
Patch by Terry Jan Reedy.
bpo-30981: IDLE -- Add more configdialog font page tests.
bpo-28523: IDLE: replace 'colour' with 'color' in configdialog.
bpo-30917: Add tests for idlelib.config.IdleConf.
Increase coverage from 46% to 96%.
Patch by Louie Lu.
bpo-30913: Document ConfigDialog tk Vars, methods, and widgets in docstrings
This will facilitate improving the dialog and splitting up the class.
Original patch by Cheryl Sabella.
bpo-30899: Add tests for ConfigParser subclasses in config.
Coverage is 100% for those classes and ConfigChanges.
Patch by Louie Lu.
bpo-30881: Add docstrings to browser.py.
Patch by Cheryl Sabella.
bpo-30851: Remove unused tk variables in configdialog.
One is a duplicate, one is set but cannot be altered by users.
Patch by Cheryl Sabella.
bpo-30870: Select font option with Up and Down keys, as well as with mouse.
Added test increases configdialog coverage to 60%
Patches mostly by Louie Lu.
bpo-8231: Call config.IdleConf.GetUserCfgDir only once per process.
bpo-30779: Factor ConfigChanges class from configdialog, put in config; test.
* In config, put dump test code in a function; run it and unittest in
'if __name__ == '__main__'.
* Add class config.ConfigChanges based on changes_class_v4.py on bpo issue.
* Add class test_config.ChangesTest, partly using configdialog_tests_v1.py.
* Revise configdialog to use ConfigChanges; see tracker msg297804.
* Revise test_configdialog to match configdialog changes.
* Remove configdialog functions unused or moved to ConfigChanges.
Cheryl Sabella contributed parts of the patch.
bpo-30777: Configdialog - add docstrings and improve comments.
Patch by Cheryl Sabella.
bpo-30495: Improve textview with docstrings, PEP8 names, and more tests.
Split TextViewer class into ViewWindow, ViewFrame, and TextFrame classes
so that instances of the latter two can be placed with other widgets
within a multiframe window.
Patches by Cheryl Sabella and Terry Jan Reedy.
bpo-30723: Make several improvements to parenmatch.
* Add 'parens' style to highlight both opener and closer.
* Make 'default' style, which is not default, a synonym for 'opener'.
* Make time-delay work the same with all styles.
* Add help for config dialog extensions tab, including parenmatch.
* Add new tests.
Original patch by Charles Wohlganger. Revisions by Terry Jan Reedy
bpo-30674: Grep -- Add docstrings. Patch by Cheryl Sabella.
bpo-21519: IDLE's basic custom key entry dialog now detects
duplicates properly. Original patch by Saimadhav Heblikar.
bpo-29910: IDLE no longer deletes a character after commenting out a
region by a key shortcut. Add "return 'break'" for this and other
potential conflicts between IDLE and default key bindings.
Patch by Serhiy Storchaka.
bpo-30728: Modernize idlelib.configdialog:
* replace import * with specific imports;
* lowercase method and attribute lines.
Patch by Cheryl Sabella.
bpo-6739: Verify user-entered key sequences by trying to bind them
with to a tk widget. Add tests for all 3 validation functions.
Original patch by G Polo. Tests added by Cheryl Sabella.
Code revised and more tests added by Terry Jan Reedy
bpo-24813: Add icon to help_about and make other changes.

- Issue #27609: IDLE: tab after initial whitespace should tab, not
autocomplete. This fixes problem with writing docstrings at least
twice indented.
- Issue #27609: Explicitly return None when there are also non-None
returns. In a few cases, reverse a condition and eliminate a return.

debugger is active (15347); b) closing the debugger with the [X] button
(15348); and c) activating the debugger when already active (24455).
The patch by Mark Roseman does this by making two changes.
1. Suspend and resume the gui.interaction method with the tcl vwait
mechanism intended for this purpose (instead of root.mainloop & .quit).
2. In gui.run, allow any existing interaction to terminate first.
- Change 'The program' to 'Your program' in an IDLE 'kill program?' message

'Save as New Custom Theme' button and enter a new name,
such as 'Custom Dark'. The custom theme will work with any IDLE
release, and can be modified.

"""Parse a Python module and describe its classes and functions.
Parse enough of a Python file to recognize imports and class and
function definitions, and to find out the superclasses of a class.
The interface consists of a single function:
readmodule_ex(module, path=None)
where module is the name of a Python module, and path is an optional
list of directories where the module is to be searched. If present,
path is prepended to the system search path sys.path. The return value
is a dictionary. The keys of the dictionary are the names of the
classes and functions defined in the module (including classes that are
defined via the from XXX import YYY construct). The values are
instances of classes Class and Function. One special key/value pair is
present for packages: the key '__path__' has a list as its value which
contains the package search path.
Classes and Functions have a common superclass: _Object. Every instance
has the following attributes:
module -- name of the module;
name -- name of the object;
file -- file in which the object is defined;
lineno -- line in the file where the object's definition starts;
parent -- parent of this object, if any;
children -- nested objects contained in this object.
The 'children' attribute is a dictionary mapping names to objects.
Instances of Function describe functions with the attributes from _Object.
Instances of Class describe classes with the attributes from _Object,
plus the following:
super -- list of super classes (Class instances if possible);
methods -- mapping of method names to beginning line numbers.
If the name of a super class is not recognized, the corresponding
entry in the list of super classes is not a class instance but a
string giving the name of the super class. Since import statements
are recognized and imported modules are scanned as well, this
shouldn't happen often.

USAGE: idle [-deins] [-t title] [file]*
idle [-dns] [-t title] (-c cmd | -r file) [arg]*
idle [-dns] [-t title] - [arg]*
-h print this help message and exit
-n run IDLE without a subprocess (DEPRECATED,
see Help/IDLE Help for details)
The following options will override the IDLE 'settings' configuration:
-e open an edit window
-i open a shell window
The following options imply -i and will open a shell:
-c cmd run the command in a shell, or
-r file run script from file
-d enable the debugger
-s run $IDLESTARTUP or $PYTHONSTARTUP before anything else
-t title set title of shell window
A default edit window will be bypassed when -c, -r, or - are used.
[arg]* are passed to the command (-c) or script (-r) in sys.argv[1:].
Examples:
idle
Open an edit window or shell depending on IDLE's configuration.
idle foo.py foobar.py
Edit the files, also open a shell if configured to start with shell.
idle -est "Baz" foo.py
Run $IDLESTARTUP or $PYTHONSTARTUP, edit foo.py, and open a shell
window with the title "Baz".
idle -c "import sys; print(sys.argv)" "foo"
Open a shell window and run the command, passing "-c" in sys.argv[0]
and "foo" in sys.argv[1].
idle -d -s -r foo.py "Hello World"
Open a shell window, run a startup script, enable the debugger, and
run foo.py, passing "foo.py" in sys.argv[0] and "Hello World" in
sys.argv[1].
echo "import sys; print(sys.argv)" | idle - "foobar"
Open a shell window, run the script piped in, passing '' in sys.argv[0]

A common problem in IDLE's interactive shell is printing of large amounts of
text into the shell. This makes looking at the previous history difficult.
Worse, this can cause IDLE to become very slow, even to the point of being
completely unusable.
This extension will automatically replace long texts with a small button.
Double-cliking this button will remove it and insert the original text instead.
Middle-clicking will copy the text to the clipboard. Right-clicking will open
the text in a separate viewing window.
Additionally, any output can be manually "squeezed" by the user. This includes
output written to the standard error stream ("stderr"), such as exception
messages and their tracebacks.

cosmopolitan/third_party/python/Lib/idlelib/CREDITS.txt | Guido van Rossum, as well as being the creator of the Python language, is the
original creator of IDLE. Other contributors prior to Version 0.8 include
Mark Hammond, Jeremy Hylton, Tim Peters, and Moshe Zadka.
IDLE's recent development was carried out in the SF IDLEfork project. The
objective was to develop a version of IDLE which had an execution environment
which could be initialized prior to each run of user code.
The IDLEfork project was initiated by David Scherer, with some help from Peter
Schneider-Kamp and Nicholas Riley. David wrote the first version of the RPC
code and designed a fast turn-around environment for VPython. Guido developed
the RPC code and Remote Debugger currently integrated in IDLE. Bruce Sherwood
contributed considerable time testing and suggesting improvements.
Besides David and Guido, the main developers who were active on IDLEfork
are Stephen M. Gava, who implemented the configuration GUI, the new
configuration system, and the About dialog, and Kurt B. Kaiser, who completed
the integration of the RPC and remote debugger, implemented the threaded
subprocess, and made a number of usability enhancements.
Other contributors include Raymond Hettinger, Tony Lownds (Mac integration),

MultiCall - a class which inherits its methods from a Tkinter widget (Text, for
example), but enables multiple calls of functions per virtual event - all
matching events will be called, not only the most specific one. This is done
by wrapping the event functions - event_add, event_delete and event_info.
MultiCall recognizes only a subset of legal event sequences. Sequences which
are not recognized are treated by the original Tk handling mechanism. A
more-specific event will be called before a less-specific event.
The recognized sequences are complete one-event sequences (no emacs-style
Ctrl-X Ctrl-C, no shortcuts like <3>), for all types of events.
Key/Button Press/Release events can have modifiers.
The recognized modifiers are Shift, Control, Option and Command for Mac, and
Control, Alt, Shift, Meta/M for other platforms.
For all events which were handled by MultiCall, a new member is added to the
event instance passed to the binded functions - mc_type. This is one of the
event type constants defined in this module (such as MC_KEYPRESS).
For Key/Button events (which are handled by MultiCall and may receive
modifiers), another member is added - mc_state. This member gives the state
of the recognized modifiers, as a combination of the modifier constants
also defined in this module (for example, MC_SHIFT).
Using these members is absolutely portable.
The order by which events are called is defined by these rules:
1. A more-specific event will be called before a less-specific event.
2. A recently-binded event will be called before a previously-binded event,
unless this conflicts with the first rule.
Each function will be called at most once for each event.

This code is generic - it works for any and all IDLE extensions.
IDLE extensions save their configuration options using idleConf.

changes using idleConf.
Not all changes take effect immediately - some may require restarting IDLE.
This depends on each extension's implementation.
All values are treated as text, and it is up to the user to supply
reasonable values. The only exception to this are the 'enable*' options,
which are boolean, and can be toggled with a True/False button.

Enable users to provisionally change foreground and background
colors applied to textual tags. Color mappings are stored in
complete listings called themes. Built-in themes in
idlelib/config-highlight.def are fixed as far as the dialog is
concerned. Any theme can be used as the base for a new custom
theme, stored in .idlerc/config-highlight.cfg.
Function load_theme_cfg() initializes tk variables and theme
lists and calls paint_theme_sample() and set_highlight_target()
for the current theme. Radiobuttons builtin_theme_on and
custom_theme_on toggle var theme_source, which controls if the
current set of colors are from a builtin or custom theme.
DynOptionMenus builtinlist and customlist contain lists of the
builtin and custom themes, respectively, and the current item
from each list is stored in vars builtin_name and custom_name.
Function paint_theme_sample() applies the colors from the theme
to the tags in text widget highlight_sample and then invokes
set_color_sample(). Function set_highlight_target() sets the state
of the radiobuttons fg_on and bg_on based on the tag and it also
invokes set_color_sample().
Function set_color_sample() sets the background color for the frame
holding the color selector. This provides a larger visual of the
color for the current tag and plane (foreground/background).
Note: set_color_sample() is called from many places and is often
called more than once when a change is made. It is invoked when
foreground or background is selected (radiobuttons), from
paint_theme_sample() (theme is changed or load_cfg is called), and
from set_highlight_target() (target tag is changed or load_cfg called).
Button delete_custom invokes delete_custom() to delete
a custom theme from idleConf.userCfg['highlight'] and changes.
Button save_custom invokes save_as_new_theme() which calls
get_new_theme_name() and create_new() to save a custom theme
and its colors to idleConf.userCfg['highlight'].
Radiobuttons fg_on and bg_on toggle var fg_bg_toggle to control
if the current selected color for a tag is for the foreground or
background.
DynOptionMenu targetlist contains a readable description of the
tags applied to Python source within IDLE. Selecting one of the
tags from this list populates highlight_target, which has a callback
function set_highlight_target().
Text widget highlight_sample displays a block of text (which is
mock Python code) in which is embedded the defined tags and reflects
the color attributes of the current theme and changes for those tags.
Mouse button 1 allows for selection of a tag and updates
highlight_target with that tag value.
Note: The font in highlight_sample is set through the config in
the fonts tab.
In other words, a tag can be selected either from targetlist or
by clicking on the sample text within highlight_sample. The
plane (foreground/background) is selected via the radiobutton.
Together, these two (tag and plane) control what color is
shown in set_color_sample() for the current theme. Button set_color
invokes get_color() which displays a ColorChooser to change the
color for the selected tag/plane. If a new color is picked,
it will be saved to changes and the highlight_sample and
frame background will be updated.
Tk Variables:
color: Color of selected target.
builtin_name: Menu variable for built-in theme.
custom_name: Menu variable for custom theme.
fg_bg_toggle: Toggle for foreground/background color.
Note: this has no callback.
theme_source: Selector for built-in or custom theme.
highlight_target: Menu variable for the highlight tag target.

def create_page_keys(self):
"""Return frame of widgets for Keys tab.
Enable users to provisionally change both individual and sets of
keybindings (shortcut keys). Except for features implemented as
extensions, keybindings are stored in complete sets called
keysets. Built-in keysets in idlelib/config-keys.def are fixed
as far as the dialog is concerned. Any keyset can be used as the
base for a new custom keyset, stored in .idlerc/config-keys.cfg.
Function load_key_cfg() initializes tk variables and keyset
lists and calls load_keys_list for the current keyset.
Radiobuttons builtin_keyset_on and custom_keyset_on toggle var
keyset_source, which controls if the current set of keybindings
are from a builtin or custom keyset. DynOptionMenus builtinlist
and customlist contain lists of the builtin and custom keysets,
respectively, and the current item from each list is stored in
vars builtin_name and custom_name.
Button delete_custom_keys invokes delete_custom_keys() to delete
a custom keyset from idleConf.userCfg['keys'] and changes. Button
save_custom_keys invokes save_as_new_key_set() which calls
get_new_keys_name() and create_new_key_set() to save a custom keyset
and its keybindings to idleConf.userCfg['keys'].
Listbox bindingslist contains all of the keybindings for the
selected keyset. The keybindings are loaded in load_keys_list()
and are pairs of (event, [keys]) where keys can be a list
of one or more key combinations to bind to the same event.
Mouse button 1 click invokes on_bindingslist_select(), which
allows button_new_keys to be clicked.
So, an item is selected in listbindings, which activates
button_new_keys, and clicking button_new_keys calls function
get_new_keys(). Function get_new_keys() gets the key mappings from the
current keyset for the binding event item that was selected. The
function then displays another dialog, GetKeysDialog, with the
selected binding event and current keys and allows new key sequences
to be entered for that binding event. If the keys aren't
changed, nothing happens. If the keys are changed and the keyset
is a builtin, function get_new_keys_name() will be called
for input of a custom keyset name. If no name is given, then the
change to the keybinding will abort and no updates will be made. If
a custom name is entered in the prompt or if the current keyset was
already custom (and thus didn't require a prompt), then
idleConf.userCfg['keys'] is updated in function create_new_key_set()
with the change to the event binding. The item listing in bindingslist
is updated with the new keys. Var keybinding is also set which invokes
the callback function, var_changed_keybinding, to add the change to
the 'keys' or 'extensions' changes tracker based on the binding type.
Tk Variables:
keybinding: Action/key bindings.
Methods:
load_keys_list: Reload active set.
create_new_key_set: Combine active keyset and changes.
set_keys_type: Command for keyset_source.
save_new_key_set: Save to idleConf.userCfg['keys'] (is function).

selected font does not define a character, Tk attempts to find another
font that does. Substitute glyphs depend on what is available on a

font selected. Line contains 20 characters up to Devanagari, 14 for
Tamil, and 10 for East Asia.
Hebrew and Arabic letters should display right to left, starting with
alef, \u05d0 and \u0627. Arabic digits display left to right. The
Devanagari and Tamil lines start with digits. The East Asian lines
are Chinese digits, Chinese Hanzi, Korean Hangul, and Japanese
Hiragana and Katakana.

cosmopolitan/third_party/python/Lib/idlelib/config.py | """idlelib.config -- Manage IDLE configuration information.
The comments at the beginning of config-main.def describe the
configuration files and the design implemented to update user
configuration information. In particular, user configuration choices
which duplicate the defaults will be removed from the user's
configuration files, and if a user file becomes empty, it will be
deleted.
The configuration database maps options to values. Conceptually, the
database keys are tuples (config-type, section, item). As implemented,
there are separate dicts for default and user values. Each has
config-type keys 'main', 'extensions', 'highlight', and 'keys'. The
value for each key is a ConfigParser instance that maps section and item
to values. For 'main' and 'extenstons', user values override
default values. For 'highlight' and 'keys', user sections augment the
default sections (and must, therefore, have distinct names).
Throughout this module there is an emphasis on returning useable defaults
when a problem occurs in returning a requested configuration value back to
idle. This is to allow IDLE to continue to function in spite of errors in
the retrieval of config information. When a default is returned instead of
a requested config value, a message is printed to stderr to aid in
configuration problem notification and resolution.

IDLEfork ChangeLog
==================
2001-07-20 11:35 elguavas
* README.txt, NEWS.txt: bring up to date for 0.8.1 release
2001-07-19 16:40 elguavas
* IDLEFORK.html: replaced by IDLEFORK-index.html
2001-07-19 16:39 elguavas
* IDLEFORK-index.html: updated placeholder idlefork homepage
2001-07-19 14:49 elguavas
* ChangeLog, EditorWindow.py, INSTALLATION, NEWS.txt, README.txt,
TODO.txt, idlever.py:
minor tidy-ups ready for 0.8.1 alpha tarball release
2001-07-17 15:12 kbk
* INSTALLATION, setup.py: INSTALLATION: Remove the coexist.patch
instructions
**************** setup.py:
Remove the idles script, add some words on IDLE Fork to the
long_description, and clean up some line spacing.
2001-07-17 15:01 kbk
* coexist.patch: Put this in the attic, at least for now...
2001-07-17 14:59 kbk
* PyShell.py, idle, idles: Implement idle command interface as
suggested by GvR [idle-dev] 16 July **************** PyShell: Added
functionality:
usage: idle.py [-c command] [-d] [-i] [-r script] [-s] [-t title]
[arg] ...
idle file(s) (without options) edit the file(s)
-c cmd run the command in a shell -d enable the
debugger -i open an interactive shell -i file(s) open a
shell and also an editor window for each file -r script run a file
as a script in a shell -s run $IDLESTARTUP or
$PYTHONSTARTUP before anything else -t title set title of shell
window
Remaining arguments are applied to the command (-c) or script (-r).
****************** idles: Removed the idles script, not needed
****************** idle: Removed the IdleConf references, not
required anymore
2001-07-16 17:08 kbk
* INSTALLATION, coexist.patch: Added installation instructions.
Added a patch which modifies idlefork so that it can co-exist with
"official" IDLE in the site-packages directory. This patch is not
necessary if only idlefork IDLE is installed. See INSTALLATION for
further details.
2001-07-16 15:50 kbk
* idles: Add a script "idles" which opens a Python Shell window.
The default behaviour of idlefork idle is to open an editor window
instead of a shell. Complex expressions may be run in a fresh
environment by selecting "run". There are times, however, when a
shell is desired. Though one can be started by "idle -t 'foo'",
this script is more convenient. In addition, a shell and an editor
window can be started in parallel by "idles -e foo.py".
2001-07-16 15:25 kbk
* PyShell.py: Call out IDLE Fork in startup message.
2001-07-16 14:00 kbk
* PyShell.py, setup.py: Add a script "idles" which opens a Python
Shell window.
The default behaviour of idlefork idle is to open an editor window
instead of a shell. Complex expressions may be run in a fresh
environment by selecting "run". There are times, however, when a
shell is desired. Though one can be started by "idle -t 'foo'",
this script is more convenient. In addition, a shell and an editor
window can be started in parallel by "idles -e foo.py".
2001-07-15 03:06 kbk
* pyclbr.py, tabnanny.py: tabnanny and pyclbr are now found in /Lib
2001-07-15 02:29 kbk
* BrowserControl.py: Remove, was retained for 1.5.2 support
2001-07-14 15:48 kbk
* setup.py: Installing Idle to site-packages via Distutils does not
copy the Idle help.txt file.
Ref SF Python Patch 422471
2001-07-14 15:26 kbk
* keydefs.py: py-cvs-2001_07_13 (Rev 1.3) merge
"Make copy, cut and paste events case insensitive. Reported by
Patrick K. O'Brien on idle-dev. (Should other bindings follow
suit?)" --GvR
2001-07-14 15:21 kbk
* idle.py: py-cvs-2001_07_13 (Rev 1.4) merge
"Move the action of loading the configuration to the IdleConf
module rather than the idle.py script. This has advantages and
disadvantages; the biggest advantage being that we can more easily
have an alternative main program." --GvR
2001-07-14 15:18 kbk
* extend.txt: py-cvs-2001_07_13 (Rev 1.4) merge
"Quick update to the extension mechanism (extend.py is gone, long
live config.txt)" --GvR
2001-07-14 15:15 kbk
* StackViewer.py: py-cvs-2001_07_13 (Rev 1.16) merge
"Refactored, with some future plans in mind. This now uses the new
gotofileline() method defined in FileList.py" --GvR
2001-07-14 15:10 kbk
* PyShell.py: py-cvs-2001_07_13 (Rev 1.34) merge
"Amazing. A very subtle change in policy in descr-branch actually
found a bug here. Here's the deal: Class PyShell derives from
class OutputWindow. Method PyShell.close() wants to invoke its
parent method, but because PyShell long ago was inherited from
class PyShellEditorWindow, it invokes
PyShelEditorWindow.close(self). Now, class PyShellEditorWindow
itself derives from class OutputWindow, and inherits the close()
method from there without overriding it. Under the old rules,
PyShellEditorWindow.close would return an unbound method restricted
to the class that defined the implementation of close(), which was
OutputWindow.close. Under the new rules, the unbound method is
restricted to the class whose method was requested, that is
PyShellEditorWindow, and this was correctly trapped as an error."
--GvR
2001-07-14 14:59 kbk
* PyParse.py: py-cvs-2001_07_13 (Rel 1.9) merge
"Taught IDLE's autoident parser that "yield" is a keyword that
begins a stmt. Along w/ the preceding change to keyword.py, making
all this work w/ a future-stmt just looks harder and harder."
--tim_one
(From Rel 1.8: "Hack to make this still work with Python 1.5.2.
;-( " --fdrake)
2001-07-14 14:51 kbk
* IdleConf.py: py-cvs-2001_07_13 (Rel 1.7) merge
"Move the action of loading the configuration to the IdleConf
module rather than the idle.py script. This has advantages and
disadvantages; the biggest advantage being that we can more easily
have an alternative main program." --GvR
2001-07-14 14:45 kbk
* FileList.py: py-cvs-2000_07_13 (Rev 1.9) merge
"Delete goodname() method, which is unused. Add gotofileline(), a
convenience method which I intend to use in a variant. Rename
test() to _test()." --GvR
This was an interesting merge. The join completely missed removing
goodname(), which was adjacent, but outside of, a small conflict.
I only caught it by comparing the 1.1.3.2/1.1.3.3 diff. CVS ain't
infallible.
2001-07-14 13:58 kbk
* EditorWindow.py: py-cvs-2000_07_13 (Rev 1.38) merge "Remove
legacy support for the BrowserControl module; the webbrowser module
has been included since Python 2.0, and that is the preferred
interface." --fdrake
2001-07-14 13:32 kbk
* EditorWindow.py, FileList.py, IdleConf.py, PyParse.py,
PyShell.py, StackViewer.py, extend.txt, idle.py, keydefs.py: Import
the 2001 July 13 23:59 GMT version of Python CVS IDLE on the
existing 1.1.3 vendor branch named py-cvs-vendor-branch. Release
tag is py-cvs-2001_07_13.

* EditorWindow.py: py-cvs-rel2_1 (Rev 1.33 - 1.37) merge
VP IDLE version depended on VP's ExecBinding.py and spawn.py to get
the path to the Windows Doc directory (relative to python.exe).
Removed this conflicting code in favor of py-cvs updates which on
Windows use a hard coded path relative to the location of this
module. py-cvs updates include support for webbrowser.py. Module
still has BrowserControl.py for 1.5.2 support.
At this point, the differences wrt py-cvs relate to menu
functionality.

original IDLE ChangeLog:
========================
Tue Feb 15 18:08:19 2000 Guido van Rossum <[email protected]>
* NEWS.txt: Notice status bar and stack viewer.
* EditorWindow.py: Support for Moshe's status bar.
* MultiStatusBar.py: Status bar code -- by Moshe Zadka.
* OldStackViewer.py:
Adding the old stack viewer implementation back, for the debugger.
* StackViewer.py: New stack viewer, uses a tree widget.
(XXX: the debugger doesn't yet use this.)
* WindowList.py:
Correct a typo and remove an unqualified except that was hiding the error.
* ClassBrowser.py: Add an XXX comment about the ClassBrowser AIP.
* ChangeLog: Updated change log.
* NEWS.txt: News update. Probably incomplete; what else is new?
* README.txt:
Updated for pending IDLE 0.5 release (still very rough -- just getting
it out in a more convenient format than CVS).
* TODO.txt: Tiny addition.
Thu Sep 9 14:16:02 1999 Guido van Rossum <[email protected]>
* TODO.txt: A few new TODO entries.
Thu Aug 26 23:06:22 1999 Guido van Rossum <[email protected]>
* Bindings.py: Add Python Documentation entry to Help menu.
* EditorWindow.py:
Find the help.txt file relative to __file__ or ".", not in sys.path.
(Suggested by Moshe Zadka, but implemented differently.)
Add <<python-docs>> event which, on Unix, brings up Netscape pointing
to http://www.python.doc/current/ (a local copy would be nice but its
location can't be predicted). Windows solution TBD.
Wed Aug 11 14:55:43 1999 Guido van Rossum <[email protected]>
* TreeWidget.py:
Moshe noticed an inconsistency in his comment, so I'm rephrasing it to
be clearer.
* TreeWidget.py:
Patch inspired by Moshe Zadka to search for the Icons directory in the
same directory as __file__, rather than searching for it along sys.path.
This works better when idle is a package.
Thu Jul 15 13:11:02 1999 Guido van Rossum <[email protected]>
* TODO.txt: New wishes.
Sat Jul 10 13:17:35 1999 Guido van Rossum <[email protected]>
* IdlePrefs.py:
Make the color for stderr red (i.e. the standard warning/danger/stop
color) rather than green. Suggested by Sam Schulenburg.
Fri Jun 25 17:26:34 1999 Guido van Rossum <[email protected]>
* PyShell.py: Close debugger when closing. This may break a cycle.
* Debugger.py: Break cycle on close.
* ClassBrowser.py: Destroy the tree when closing.
* TreeWidget.py: Add destroy() method to recursively destroy a tree.
* PyShell.py: Extend _close() to break cycles.
Break some other cycles too (and destroy the root when done).
* EditorWindow.py:
Add _close() method that does the actual cleanup (close() asks the
user what they want first if there's unsaved stuff, and may cancel).
It closes more than before.
Add unload_extensions() method to unload all extensions; called from
_close(). It calls an extension's close() method if it has one.
* Percolator.py: Add close() method that breaks cycles.
* WidgetRedirector.py: Add unregister() method.
Unregister everything at closing.
Don't call close() in __del__, rely on explicit call to close().
* IOBinding.py, FormatParagraph.py, CallTips.py:
Add close() method that breaks a cycle.
Fri Jun 11 15:03:00 1999 Guido van Rossum <[email protected]>
* AutoIndent.py, EditorWindow.py, FormatParagraph.py:
Tim Peters smart.patch:
EditorWindow.py:
+ Added get_tabwidth & set_tabwidth "virtual text" methods, that get/set the
widget's view of what a tab means.
+ Moved TK_TABWIDTH_DEFAULT here from AutoIndent.
+ Renamed Mark's get_selection_index to get_selection_indices (sorry, Mark,
but the name was plain wrong <wink>).
FormatParagraph.py: renamed use of get_selection_index.
AutoIndent.py:
+ Moved TK_TABWIDTH_DEFAULT to EditorWindow.
+ Rewrote set_indentation_params to use new VTW get/set_tabwidth methods.
+ Changed smart_backspace_event to delete whitespace back to closest
preceding virtual tab stop or real character (note that this may require
inserting characters if backspacing over a tab!).
+ Nuked almost references to the selection tag, in favor of using
get_selection_indices. The sole exception is in set_region, for which no
"set_selection" abstraction has yet been agreed upon.
+ Had too much fun using the spiffy new features of the format-paragraph
cmd.
Thu Jun 10 17:48:02 1999 Guido van Rossum <[email protected]>
* FormatParagraph.py:
Code by Mark Hammond to format paragraphs embedded in comments.
Read the comments (which I reformatted using the new feature :-)
for some limitations.
* EditorWindow.py:
Added abstraction get_selection_index() (Mark Hammond). Also
reformatted some comment blocks to show off a cool feature I'm about
to check in next.
* ClassBrowser.py:
Adapt to the new pyclbr's support of listing top-level functions. If
this functionality is not present (e.g. when used with a vintage
Python 1.5.2 installation) top-level functions are not listed.
(Hmm... Any distribution of IDLE 0.5 should probably include a copy
of the new pyclbr.py!)
* AutoIndent.py:
Fix off-by-one error in Tim's recent change to comment_region(): the
list of lines returned by get_region() contains an empty line at the
end representing the start of the next line, and this shouldn't be
commented out!
* CallTips.py:
Mark Hammond writes: Here is another change that allows it to work for
class creation - tries to locate an __init__ function. Also updated
the test code to reflect your new "***" change.
* CallTipWindow.py:
Mark Hammond writes: Tim's suggestion of copying the font for the
CallTipWindow from the text control makes sense, and actually makes
the control look better IMO.
Wed Jun 9 20:34:57 1999 Guido van Rossum <[email protected]>
* CallTips.py:
Append "..." if the appropriate flag (for varargs) in co_flags is set.
Ditto "***" for kwargs.
Tue Jun 8 13:06:07 1999 Guido van Rossum <[email protected]>
* ReplaceDialog.py:
Hmm... Tim didn't turn "replace all" into a single undo block.
I think I like it better if it os, so here.
* ReplaceDialog.py: Tim Peters: made replacement atomic for undo/redo.
* AutoIndent.py: Tim Peters:
+ Set usetabs=1. Editing pyclbr.py was driving me nuts <0.6 wink>.
usetabs=1 is the Emacs pymode default too, and thanks to indentwidth !=
tabwidth magical usetabs disabling, new files are still created with tabs
turned off. The only implication is that if you open a file whose first
indent is a single tab, IDLE will now magically use tabs for that file (and
set indentwidth to 8). Note that the whole scheme doesn't work right for
PythonWin, though, since Windows users typically set tabwidth to 4; Mark
probably has to hide the IDLE algorithm from them (which he already knows).
+ Changed comment_region_event to stick "##" in front of every line. The
"holes" previously left on blank lines were visually confusing (made it
needlessly hard to figure out what to uncomment later).
Mon Jun 7 15:38:40 1999 Guido van Rossum <[email protected]>
* TreeWidget.py, ObjectBrowser.py:
Remove unnecessary reference to pyclbr from test() code.
* PyParse.py: Tim Peters:
Smarter logic for finding a parse synch point.
Does a half to a fifth the work in normal cases; don't notice the speedup,
but makes more breathing room for other extensions.
Speeds terrible cases by at least a factor of 10. "Terrible" == e.g. you put
""" at the start of Tkinter.py, undo it, zoom to the bottom, and start
typing in code. Used to take about 8 seconds for ENTER to respond, now some
large fraction of a second. The new code gets indented correctly, despite
that it all remains "string colored" until the colorizer catches up (after
which, ENTER appears instantaneous again).
Fri Jun 4 19:21:19 1999 Guido van Rossum <[email protected]>
* extend.py: Might as well enable CallTips by default.
If there are too many complaints I'll remove it again or fix it.
Thu Jun 3 14:32:16 1999 Guido van Rossum <[email protected]>
* AutoIndent.py, EditorWindow.py, PyParse.py:
New offerings by Tim Peters; he writes:
IDLE is now the first Python editor in the Universe not confused by my
doctest.py <wink>.
As threatened, this defines IDLE's is_char_in_string function as a
method of EditorWindow. You just need to define one similarly in
whatever it is you pass as editwin to AutoIndent; looking at the
EditorWindow.py part of the patch should make this clear.
* GrepDialog.py: Enclose pattern in quotes in status message.
* CallTips.py:
Mark Hammond fixed some comments and improved the way the tip text is
constructed.
Wed Jun 2 18:18:57 1999 Guido van Rossum <[email protected]>
* CallTips.py:
My fix to Mark's code: restore the universal check on <KeyRelease>.
Always cancel on <Key-Escape> or <ButtonPress>.
* CallTips.py:
A version that Mark Hammond posted to the newsgroup. Has some newer
stuff for getting the tip. Had to fix the Key-( and Key-) events
for Unix. Will have to re-apply my patch for catching KeyRelease and
ButtonRelease events.
* CallTipWindow.py, CallTips.py:
Call tips by Mark Hammond (plus tiny fix by me.)
* IdleHistory.py:
Changes by Mark Hammond: (1) support optional output_sep argument to
the constructor so he can eliminate the sys.ps2 that PythonWin leaves
in the source; (2) remove duplicate history items.
* AutoIndent.py:
Changes by Mark Hammond to allow using IDLE extensions in PythonWin as
well: make three dialog routines instance variables.
* EditorWindow.py:
Change by Mark Hammond to allow using IDLE extensions in PythonWin as
well: make three dialog routines instance variables.
Tue Jun 1 20:06:44 1999 Guido van Rossum <[email protected]>
* AutoIndent.py: Hah! A fix of my own to Tim's code!
Unix bindings for <<toggle-tabs>> and <<change-indentwidth>> were
missing, and somehow that meant the events were never generated,
even though they were in the menu. The new Unix bindings are now
the same as the Windows bindings (M-t and M-u).
* AutoIndent.py, PyParse.py, PyShell.py: Tim Peters again:
The new version (attached) is fast enough all the time in every real module
I have <whew!>. You can make it slow by, e.g., creating an open list with
5,000 90-character identifiers (+ trailing comma) each on its own line, then
adding an item to the end -- but that still consumes less than a second on
my P5-166. Response time in real code appears instantaneous.
Fixed some bugs.
New feature: when hitting ENTER and the cursor is beyond the line's leading
indentation, whitespace is removed on both sides of the cursor; before
whitespace was removed only on the left; e.g., assuming the cursor is
between the comma and the space:
def something(arg1, arg2):
^ cursor to the left of here, and hit ENTER
arg2): # new line used to end up here
arg2): # but now lines up the way you expect
New hack: AutoIndent has grown a context_use_ps1 Boolean config option,
defaulting to 0 (false) and set to 1 (only) by PyShell. Reason: handling
the fancy stuff requires looking backward for a parsing synch point; ps1
lines are the only sensible thing to look for in a shell window, but are a
bad thing to look for in a file window (ps1 lines show up in my module
docstrings often). PythonWin's shell should set this true too.
Persistent problem: strings containing def/class can still screw things up
completely. No improvement. Simplest workaround is on the user's head, and
consists of inserting e.g.
def _(): pass
(or any other def/class) after the end of the multiline string that's
screwing them up. This is especially irksome because IDLE's syntax coloring
is *not* confused, so when this happens the colors don't match the
indentation behavior they see.
* AutoIndent.py: Tim Peters again:
[Tim, after adding some bracket smarts to AutoIndent.py]
> ...
> What it can't possibly do without reparsing large gobs of text is
> suggest a reasonable indent level after you've *closed* a bracket
> left open on some previous line.
> ...
The attached can, and actually fast enough to use -- most of the time. The
code is tricky beyond belief to achieve that, but it works so far; e.g.,
return len(string.expandtabs(str[self.stmt_start :
^ indents to caret
i],
^ indents to caret
self.tabwidth)) + 1
^ indents to caret
It's about as smart as pymode now, wrt both bracket and backslash
continuation rules. It does require reparsing large gobs of text, and if it
happens to find something that looks like a "def" or "class" or sys.ps1
buried in a multiline string, but didn't suck up enough preceding text to
see the start of the string, it's completely hosed. I can't repair that --
it's just too slow to reparse from the start of the file all the time.
AutoIndent has grown a new num_context_lines tuple attribute that controls
how far to look back, and-- like other params --this could/should be made
user-overridable at startup and per-file on the fly.
* PyParse.py: New file by Tim Peters:
One new file in the attached, PyParse.py. The LineStudier (whatever it was
called <wink>) class was removed from AutoIndent; PyParse subsumes its
functionality.
* AutoIndent.py: Tim Peters keeps revising this module (more to come):
Removed "New tabwidth" menu binding.
Added "a tab means how many spaces?" dialog to block tabify and untabify. I
think prompting for this is good now: they're usually at-most-once-per-file
commands, and IDLE can't let them change tabwidth from the Tk default
anymore, so IDLE can no longer presume to have any idea what a tab means.
Irony: for the purpose of keeping comments aligned via tabs, Tk's
non-default approach is much nicer than the Emacs/Notepad/Codewright/vi/etc
approach.
* EditorWindow.py:
1. Catch NameError on import (could be raised by case mismatch on Windows).
2. No longer need to reset pyclbr cache and show watch cursor when calling
ClassBrowser -- the ClassBrowser takes care of pyclbr and the TreeWidget
takes care of the watch cursor.
3. Reset the focus to the current window after error message about class
browser on buffer without filename.
* Icons/minusnode.gif, Icons/plusnode.gif: Missed a few.
* ClassBrowser.py, PathBrowser.py: Rewritten based on TreeWidget.py
* ObjectBrowser.py: Object browser, based on TreeWidget.py.
* TreeWidget.py: Tree widget done right.
* ToolTip.py: As yet unused code for tool tips.
* ScriptBinding.py:
Ensure sys.argv[0] is the script name on Run Script.
* ZoomHeight.py: Move zoom height functionality to separate function.
* Icons/folder.gif, Icons/openfolder.gif, Icons/python.gif, Icons/tk.gif:
A few icons used by ../TreeWidget.py and its callers.
* AutoIndent.py: New version by Tim Peters improves block opening test.
Fri May 21 04:46:17 1999 Guido van Rossum <[email protected]>
* Attic/History.py, PyShell.py: Rename History to IdleHistory.
Add isatty() to pseudo files.
* StackViewer.py: Make initial stack viewer wider
* TODO.txt: New wishes
* AutoIndent.py, EditorWindow.py, PyShell.py:
Much improved autoindent and handling of tabs,
by Tim Peters.
Mon May 3 15:49:52 1999 Guido van Rossum <[email protected]>
* AutoIndent.py, EditorWindow.py, FormatParagraph.py, UndoDelegator.py:
Tim Peters writes:
I'm still unsure, but couldn't stand the virtual event trickery so tried a
different sin (adding undo_block_start/stop methods to the Text instance in
EditorWindow.py). Like it or not, it's efficient and works <wink>. Better
idea?
Give the attached a whirl. Even if you hate the implementation, I think
you'll like the results. Think I caught all the "block edit" cmds,
including Format Paragraph, plus subtler ones involving smart indents and
backspacing.
* WidgetRedirector.py: Tim Peters writes:
[W]hile trying to dope out how redirection works, stumbled into two
possible glitches. In the first, it doesn't appear to make sense to try to
rename a command that's already been destroyed; in the second, the name
"previous" doesn't really bring to mind "ignore the previous value" <wink>.
Fri Apr 30 19:39:25 1999 Guido van Rossum <[email protected]>
* __init__.py: Support for using idle as a package.
* PathBrowser.py:
Avoid listing files more than once (e.g. foomodule.so has two hits:
once for foo + module.so, once for foomodule + .so).
Mon Apr 26 22:20:38 1999 Guido van Rossum <[email protected]>
* ChangeLog, ColorDelegator.py, PyShell.py: Tim Peters strikes again:
Ho ho ho -- that's trickier than it sounded! The colorizer is working with
"line.col" strings instead of Text marks, and the absolute coordinates of
the point of interest can change across the self.update call (voice of
baffled experience, when two quick backspaces no longer fooled it, but a
backspace followed by a quick ENTER did <wink>).
Anyway, the attached appears to do the trick. CPU usage goes way up when
typing quickly into a long triple-quoted string, but the latency is fine for
me (a relatively fast typist on a relatively slow machine). Most of the
changes here are left over from reducing the # of vrbl names to help me
reason about the logic better; I hope the code is a *little* easier to
Fri Apr 23 14:01:25 1999 Guido van Rossum <[email protected]>
* EditorWindow.py:
Provide full arguments to __import__ so it works in packagized IDLE.
Thu Apr 22 23:20:17 1999 Guido van Rossum <[email protected]>
* help.txt:
Bunch of updates necessary due to recent changes; added docs for File
menu, command line and color preferences.
* Bindings.py: Remove obsolete 'script' menu.
* TODO.txt: Several wishes fulfilled.
* OutputWindow.py:
Moved classes OnDemandOutputWindow and PseudoFile here,
from ScriptBinding.py where they are no longer needed.
* ScriptBinding.py:
Mostly rewritten. Instead of the old Run module and Debug module,
there are two new commands:
Import module (F5) imports or reloads the module and also adds its
name to the __main__ namespace. This gets executed in the PyShell
window under control of its debug settings.
Run script (Control-F5) is similar but executes the contents of the
file directly in the __main__ namespace.
* PyShell.py: Nits: document use of $IDLESTARTUP; display idle version
* idlever.py: New version to celebrate new command line
* OutputWindow.py: Added flush(), for completeness.
* PyShell.py:
A lot of changes to make the command line more useful. You can now do:
idle.py -e file ... -- to edit files
idle.py script arg ... -- to run a script
idle.py -c cmd arg ... -- to run a command
Other options, see also the usage message (also new!) for more details:
-d -- enable debugger
-s -- run $IDLESTARTUP or $PYTHONSTARTUP
-t title -- set Python Shell window's title
sys.argv is set accordingly, unless -e is used.
sys.path is absolutized, and all relevant paths are inserted into it.
Other changes:
- the environment in which commands are executed is now the
__main__ module
- explicitly save sys.stdout etc., don't restore from sys.__stdout__
- new interpreter methods execsource(), execfile(), stuffsource()
- a few small nits
* TODO.txt:
Some more TODO items. Made up my mind about command line args,
Run/Import, __main__.
* ColorDelegator.py:
Super-elegant patch by Tim Peters that speeds up colorization
dramatically (up to 15 times he claims). Works by reading more than
one line at a time, up to 100-line chunks (starting with one line and
then doubling up to the limit). On a typical machine (e.g. Tim's
P5-166) this doesn't reduce interactive responsiveness in a noticeable
way.
Wed Apr 21 15:49:34 1999 Guido van Rossum <[email protected]>
* ColorDelegator.py:
Patch by Tim Peters to speed up colorizing of big multiline strings.
Tue Apr 20 17:32:52 1999 Guido van Rossum <[email protected]>
* extend.txt:
For an event 'foo-bar', the corresponding method must be called
foo_bar_event(). Therefore, fix the references to zoom_height() in
the example.
* IdlePrefs.py: Restored the original IDLE color scheme.
* PyShell.py, IdlePrefs.py, ColorDelegator.py, EditorWindow.py:
Color preferences code by Loren Luke (massaged by me somewhat)
* SearchEngine.py:
Patch by Mark Favas: it fixes the search engine behaviour where an
unsuccessful search wraps around and re-searches that part of the file
between the start of the search and the end of the file - only really
an issue for very large files, but... (also removes a redundant
m.span() call).
Mon Apr 19 16:26:02 1999 Guido van Rossum <[email protected]>
* TODO.txt: A few wishes are now fulfilled.
* AutoIndent.py: Tim Peters implements some of my wishes:
o Makes the tab key intelligently insert spaces when appropriate
(see Help list banter twixt David Ascher and me; idea stolen from
every other editor on earth <wink>).
o newline_and_indent_event trims trailing whitespace on the old
line (pymode and Codewright).
o newline_and_indent_event no longer fooled by trailing whitespace or
comment after ":" (pymode, PTUI).
o newline_and_indent_event now reduces the new line's indentation after
return, break, continue, raise and pass stmts (pymode).
The last two are easy to fool in the presence of strings &
continuations, but pymode requires Emacs's high-powered C parsing
functions to avoid that in finite time.
======================================================================
Python release 1.5.2c1, IDLE version 0.4
======================================================================
Wed Apr 7 18:41:59 1999 Guido van Rossum <[email protected]>
* README.txt, NEWS.txt: New version.
* idlever.py: Version bump awaiting impending new release.
(Not much has changed :-( )
Mon Mar 29 14:52:28 1999 Guido van Rossum <[email protected]>
* ScriptBinding.py, PyShell.py:
At Tim Peters' recommendation, add a dummy flush() method to
PseudoFile.
Thu Mar 11 23:21:23 1999 Guido van Rossum <[email protected]>
* PathBrowser.py: Don't crash when sys.path contains an empty string.
* Attic/Outline.py: This file was never supposed to be part of IDLE.
* PathBrowser.py:
- Don't crash in the case where a superclass is a string instead of a
pyclbr.Class object; this can happen when the superclass is
unrecognizable (to pyclbr), e.g. when module renaming is used.
- Show a watch cursor when calling pyclbr (since it may take a while
recursively parsing imported modules!).
Wed Mar 10 05:18:02 1999 Guido van Rossum <[email protected]>
* EditorWindow.py, Bindings.py: Add PathBrowser to File module
* PathBrowser.py: "Path browser" - 4 scrolled lists displaying:
directories on sys.path
modules in selected directory
classes in selected module
methods of selected class
Sinlge clicking in a directory, module or class item updates the next
column with info about the selected item. Double clicking in a
module, class or method item opens the file (and selects the clicked
item if it is a class or method).
I guess eventually I should be using a tree widget for this, but the
ones I've seen don't work well enough, so for now I use the old
Smalltalk or NeXT style multi-column hierarchical browser.
* MultiScrolledLists.py:
New utility: multiple scrolled lists in parallel
* ScrolledList.py: - White background.
- Display "(None)" (or text of your choosing) when empty.
- Don't set the focus.
======================================================================
Python release 1.5.2b2, IDLE version 0.3
======================================================================
Wed Feb 17 22:47:41 1999 Guido van Rossum <[email protected]>
* NEWS.txt: News in 0.3.
* README.txt, idlever.py: Bump version to 0.3.
* EditorWindow.py:
After all, we don't need to call the callbacks ourselves!
* WindowList.py:
When deleting, call the callbacks *after* deleting the window from our list!
* EditorWindow.py:
Fix up the Windows menu via the new callback mechanism instead of
depending on menu post commands (which don't work when the menu is
torn off).
* WindowList.py:
Support callbacks to patch up Windows menus everywhere.
* ChangeLog: Oh, why not. Checking in the Emacs-generated change log.
Tue Feb 16 22:34:17 1999 Guido van Rossum <[email protected]>
* ScriptBinding.py:
Only pop up the stack viewer when requested in the Debug menu.
Mon Feb 8 22:27:49 1999 Guido van Rossum <[email protected]>
* WindowList.py: Don't crash if a window no longer exists.
* TODO.txt: Restructured a bit.
Mon Feb 1 23:06:17 1999 Guido van Rossum <[email protected]>
* PyShell.py: Add current dir or paths of file args to sys.path.
* Debugger.py: Add canonic() function -- for brand new bdb.py feature.
* StackViewer.py: Protect against accessing an empty stack.
Fri Jan 29 20:44:45 1999 Guido van Rossum <[email protected]>
* ZoomHeight.py:
Use only the height to decide whether to zoom in or out.
Thu Jan 28 22:24:30 1999 Guido van Rossum <[email protected]>
* EditorWindow.py, FileList.py:
Make sure the Tcl variables are shared between windows.
* PyShell.py, EditorWindow.py, Bindings.py:
Move menu/key binding code from Bindings.py to EditorWindow.py,
with changed APIs -- it makes much more sense there.
Also add a new feature: if the first character of a menu label is
a '!', it gets a checkbox. Checkboxes are bound to Boolean Tcl variables
that can be accessed through the new getvar/setvar/getrawvar API;
the variable is named after the event to which the menu is bound.
* Debugger.py: Add Quit button to the debugger window.
* SearchDialog.py:
When find_again() finds exactly the current selection, it's a failure.
* idle.py, Attic/idle: Rename idle -> idle.py
Mon Jan 18 15:18:57 1999 Guido van Rossum <[email protected]>
* EditorWindow.py, WindowList.py: Only deiconify when iconic.
* TODO.txt: Misc
Tue Jan 12 22:14:34 1999 Guido van Rossum <[email protected]>
* testcode.py, Attic/test.py:
Renamed test.py to testcode.py so one can import Python's
test package from inside IDLE. (Suggested by Jack Jansen.)
* EditorWindow.py, ColorDelegator.py:
Hack to close a window that is colorizing.
* Separator.py: Vladimir Marangozov's patch:
The separator dances too much and seems to jump by arbitrary amounts
in arbitrary directions when I try to move it for resizing the frames.
This patch makes it more quiet.
Mon Jan 11 14:52:40 1999 Guido van Rossum <[email protected]>
* TODO.txt: Some requests have been fulfilled.
* EditorWindow.py:
Set the cursor to a watch when opening the class browser (which may
take quite a while, browsing multiple files).
Newer, better center() -- but assumes no wrapping.
* SearchBinding.py:
Got rid of debug print statement in goto_line_event().
* ScriptBinding.py:
I think I like it better if it prints the traceback even when it displays
the stack viewer.
* Debugger.py: Bind ESC to close-window.
* ClassBrowser.py: Use a HSeparator between the classes and the items.
Make the list of classes wider by default (40 chars).
Bind ESC to close-window.
* Separator.py:
Separator classes (draggable divider between two panes).
Sat Jan 9 22:01:33 1999 Guido van Rossum <[email protected]>
* WindowList.py:
Don't traceback when wakeup() is called when the window has been destroyed.
This can happen when a torn-of Windows menu references closed windows.
And Tim Peters claims that the Windows menu is his favorite to tear off...
* EditorWindow.py: Allow tearing off of the Windows menu.
* StackViewer.py: Close on ESC.
* help.txt: Updated a bunch of things (it was mostly still 0.1!)
* extend.py: Added ScriptBinding to standard bindings.
* ScriptBinding.py:
This now actually works. See doc string. It can run a module (i.e.
import or reload) or debug it (same with debugger control). Output
goes to a fresh output window, only created when needed.
======================================================================
Python release 1.5.2b1, IDLE version 0.2
======================================================================
Fri Jan 8 17:26:02 1999 Guido van Rossum <[email protected]>
* README.txt, NEWS.txt: What's new in this release.
* Bindings.py, PyShell.py:
Paul Prescod's patches to allow the stack viewer to pop up when a
traceback is printed.
Thu Jan 7 00:12:15 1999 Guido van Rossum <[email protected]>
* FormatParagraph.py:
Change paragraph width limit to 70 (like Emacs M-Q).
* README.txt:
Separating TODO from README. Slight reformulation of features. No
exact release date.
* TODO.txt: Separating TODO from README.
Mon Jan 4 21:19:09 1999 Guido van Rossum <[email protected]>
* FormatParagraph.py:
Hm. There was a boundary condition error at the end of the file too.
* SearchBinding.py: Hm. Add Unix binding for replace, too.
* keydefs.py: Ran eventparse.py again.
* FormatParagraph.py: Added Unix Meta-q key binding;
fix find_paragraph when at start of file.
* AutoExpand.py: Added Meta-/ binding for Unix as alt for Alt-/.
* SearchBinding.py:
Add unix binding for grep (otherwise the menu entry doesn't work!)
* ZoomHeight.py: Adjusted Unix height to work with fvwm96. :=(
* GrepDialog.py: Need to import sys!
* help.txt, extend.txt, README.txt: Formatted some paragraphs
* extend.py, FormatParagraph.py:
Add new extension to reformat a (text) paragraph.
* ZoomHeight.py: Typo in Win specific height setting.
Sun Jan 3 00:47:35 1999 Guido van Rossum <[email protected]>
* AutoIndent.py: Added something like Tim Peters' backspace patch.
* ZoomHeight.py: Adapted to Unix (i.e., more hardcoded constants).
Sat Jan 2 21:28:54 1999 Guido van Rossum <[email protected]>
* keydefs.py, idlever.py, idle.pyw, idle.bat, help.txt, extend.txt, extend.py, eventparse.py, ZoomHeight.py, WindowList.py, UndoDelegator.py, StackViewer.py, SearchEngine.py, SearchDialogBase.py, SearchDialog.py, ScrolledList.py, SearchBinding.py, ScriptBinding.py, ReplaceDialog.py, Attic/README, README.txt, PyShell.py, Attic/PopupMenu.py, OutputWindow.py, IOBinding.py, Attic/HelpWindow.py, History.py, GrepDialog.py, FileList.py, FrameViewer.py, EditorWindow.py, Debugger.py, Delegator.py, ColorDelegator.py, Bindings.py, ClassBrowser.py, AutoExpand.py, AutoIndent.py:
Checking in IDLE 0.2.
Much has changed -- too much, in fact, to write down.
The big news is that there's a standard way to write IDLE extensions;
see extend.txt. Some sample extensions have been provided, and
some existing code has been converted to extensions. Probably the
biggest new user feature is a new search dialog with more options,
search and replace, and even search in files (grep).
This is exactly as downloaded from my laptop after returning
from the holidays -- it hasn't even been tested on Unix yet.
Fri Dec 18 15:52:54 1998 Guido van Rossum <[email protected]>
* FileList.py, ClassBrowser.py:
Fix the class browser to work even when the file is not on sys.path.
Tue Dec 8 20:39:36 1998 Guido van Rossum <[email protected]>
* Attic/turtle.py: Moved to Python 1.5.2/Lib
Fri Nov 27 03:19:20 1998 Guido van Rossum <[email protected]>
* help.txt: Typo
* EditorWindow.py, FileList.py: Support underlining of menu labels
* Bindings.py:
New approach, separate tables for menus (platform-independent) and key
definitions (platform-specific), and generating accelerator strings
automatically from the key definitions.
Mon Nov 16 18:37:42 1998 Guido van Rossum <[email protected]>
* Attic/README: Clarify portability and main program.
* Attic/README: Added intro for 0.1 release and append Grail notes.
Mon Oct 26 18:49:00 1998 Guido van Rossum <[email protected]>
* Attic/turtle.py: root is now a global called _root
Sat Oct 24 16:38:38 1998 Guido van Rossum <[email protected]>
* Attic/turtle.py: Raise the root window on reset().
Different action on WM_DELETE_WINDOW is more likely to do the right thing,
allowing us to destroy old windows.
* Attic/turtle.py:
Split the goto() function in two: _goto() is the internal one,
using Canvas coordinates, and goto() uses turtle coordinates
and accepts variable argument lists.
* Attic/turtle.py: Cope with destruction of the window
* Attic/turtle.py: Turtle graphics
* Debugger.py: Use of Breakpoint class should be bdb.Breakpoint.
Mon Oct 19 03:33:40 1998 Guido van Rossum <[email protected]>
* SearchBinding.py:
Speed up the search a bit -- don't drag a mark around...
* PyShell.py:
Change our special entries from <console#N> to <pyshell#N>.
Patch linecache.checkcache() to keep our special entries alive.
Add popup menu to all editor windows to set a breakpoint.
* Debugger.py:
Use and pass through the 'force' flag to set_dict() where appropriate.
Default source and globals checkboxes to false.
Don't interact in user_return().
Add primitive set_breakpoint() method.
* ColorDelegator.py:
Raise priority of 'sel' tag so its foreground (on Windows) will take
priority over text colorization (which on Windows is almost the
same color as the selection background).
Define a tag and color for breakpoints ("BREAK").
* Attic/PopupMenu.py: Disable "Open stack viewer" and "help" commands.
* StackViewer.py:
Add optional 'force' argument (default 0) to load_dict().
If set, redo the display even if it's the same dict.
Fri Oct 16 21:10:12 1998 Guido van Rossum <[email protected]>
* StackViewer.py: Do nothing when loading the same dict as before.
* PyShell.py: Details for debugger interface.
* Debugger.py:
Restructured and more consistent. Save checkboxes across instantiations.
* EditorWindow.py, Attic/README, Bindings.py:
Get rid of conflicting ^X binding. Use ^W.
* Debugger.py, StackViewer.py:
Debugger can now show local and global variables.
* Debugger.py: Oops
* Debugger.py, PyShell.py: Better debugger support (show stack etc).
* Attic/PopupMenu.py: Follow renames in StackViewer module
* StackViewer.py:
Rename classes to StackViewer (the widget) and StackBrowser (the toplevel).
* ScrolledList.py: Add close() method
* EditorWindow.py: Clarify 'Open Module' dialog text
* StackViewer.py: Restructured into a browser and a widget.
Thu Oct 15 23:27:08 1998 Guido van Rossum <[email protected]>
* ClassBrowser.py, ScrolledList.py:
Generalized the scrolled list which is the base for the class and
method browser into a separate class in its own module.
* Attic/test.py: Cosmetic change
* Debugger.py: Don't show function name if there is none
Wed Oct 14 03:43:05 1998 Guido van Rossum <[email protected]>
* Debugger.py, PyShell.py: Polish the Debugger GUI a bit.
Closing it now also does the right thing.
Tue Oct 13 23:51:13 1998 Guido van Rossum <[email protected]>
* Debugger.py, PyShell.py, Bindings.py:
Ad primitive debugger interface (so far it will step and show you the
source, but it doesn't yet show the stack).
* Attic/README: Misc
* StackViewer.py: Whoops -- referenced self.top before it was set.
* help.txt: Added history and completion commands.
* help.txt: Updated
* FileList.py: Add class browser functionality.
* StackViewer.py:
Add a close() method and bind to WM_DELETE_WINDOW protocol
* PyShell.py: Clear the linecache before printing a traceback
* Bindings.py: Added class browser binding.
* ClassBrowser.py: Much improved, much left to do.
* PyShell.py: Make the return key do what I mean more often.
* ClassBrowser.py:
Adding the beginnings of a Class browser. Incomplete, yet.
* EditorWindow.py, Bindings.py:
Add new command, "Open module". You select or type a module name,
and it opens the source.
Mon Oct 12 23:59:27 1998 Guido van Rossum <[email protected]>
* PyShell.py: Subsume functionality from Popup menu in Debug menu.
Other stuff so the PyShell window can be resurrected from the Windows menu.
* FileList.py: Get rid of PopUp menu.
Create a simple Windows menu. (Imperfect when Untitled windows exist.)
Add wakeup() method: deiconify, raise, focus.
* EditorWindow.py: Generalize menu creation.
* Bindings.py: Add Debug and Help menu items.
* EditorWindow.py: Added a menu bar to every window.
* Bindings.py: Add menu configuration to the event configuration.
* Attic/PopupMenu.py: Pass a root to the help window.
* SearchBinding.py:
Add parent argument to 'go to line number' dialog box.
Sat Oct 10 19:15:32 1998 Guido van Rossum <[email protected]>
* StackViewer.py:
Add a label at the top showing (very basic) help for the stack viewer.
Add a label at the bottom showing the exception info.
* Attic/test.py, Attic/idle: Add Unix main script and test program.
* idle.pyw, help.txt, WidgetRedirector.py, UndoDelegator.py, StackViewer.py, SearchBinding.py, Attic/README, PyShell.py, Attic/PopupMenu.py, Percolator.py, Outline.py, IOBinding.py, History.py, Attic/HelpWindow.py, FrameViewer.py, FileList.py, EditorWindow.py, Delegator.py, ColorDelegator.py, Bindings.py, AutoIndent.py, AutoExpand.py:
Initial checking of Tk-based Python IDE.
Features: text editor with syntax coloring and undo;
subclassed into interactive Python shell which adds history.

# 'enable_editor' or 'enable_shell' items, to apply it only to editor ir
# shell windows, and may also contain any other general configuration
# items for the extension. Other True/False values will also be
# recognized as boolean by the Extension Configuration dialog.
#
# Each extension must define at least one section named
# ExtensionName_bindings or ExtensionName_cfgBindings. If present,
# ExtensionName_bindings defines virtual event bindings for the

"""Support for redirecting arbitrary widget subcommands.
Some Tk operations don't normally pass through tkinter. For example, if a
character is inserted into a Text widget by pressing a key, a default Tk
binding to the widget's 'insert' operation is activated, and the Tk library
processes the insert without calling back into tkinter.
Although a binding to <Key> could be made via tkinter, what we really want
to do is to hook the Tk 'insert' operation itself. For one thing, we want
a text.insert call in idle code to have the same effect as a key press.
When a widget is instantiated, a Tcl command is created whose name is the
same as the pathname widget._w. This command is used to invoke the various
widget operations, e.g. insert (for a Text widget). We are going to hook
this command and provide a facility ('register') to intercept the widget
operation. We will also intercept method calls on the tkinter class
instance that represents the tk widget.
In IDLE, WidgetRedirector is used in Percolator to intercept Text
commands. The function being registered provides access to the top
of a Percolator chain. At the bottom of the chain is a call to the
original Tk widget operation.

cosmopolitan/third_party/python/Lib/idlelib/idle_test/README.txt | README FOR IDLE TESTS IN IDLELIB.IDLE_TEST
0. Quick Start
Automated unit tests were added in 3.3 for Python 3.x.
To run the tests from a command line:
python -m test.test_idle
Human-mediated tests were added later in 3.4.
python -m idlelib.idle_test.htest
1. Test Files
The idle directory, idlelib, has over 60 xyz.py files. The idle_test
subdirectory contains test_xyz.py for each implementation file xyz.py.
To add a test for abc.py, open idle_test/template.py and immediately
Save As test_abc.py. Insert 'abc' on the first line, and replace
'zzdummy' with 'abc.
Remove the imports of requires and tkinter if not needed. Otherwise,
add to the tkinter imports as needed.
Add a prefix to 'Test' for the initial test class. The template class
contains code needed or possibly needed for gui tests. See the next
section if doing gui tests. If not, and not needed for further classes,
this code can be removed.
Add the following at the end of abc.py. If an htest was added first,
insert the import and main lines before the htest lines.
if __name__ == "__main__":
from unittest import main
main('idlelib.idle_test.test_abc', verbosity=2, exit=False)
The ', exit=False' is only needed if an htest follows.
2. GUI Tests
When run as part of the Python test suite, Idle GUI tests need to run
test.support.requires('gui'). A test is a GUI test if it creates a
tkinter.Tk root or master object either directly or indirectly by
instantiating a tkinter or idle class. GUI tests cannot run in test
processes that either have no graphical environment available or are not
allowed to use it.
To guard a module consisting entirely of GUI tests, start with
from test.support import requires
requires('gui')
To guard a test class, put "requires('gui')" in its setUpClass function.
The template.py file does this.
To avoid interfering with other GUI tests, all GUI objects must be
destroyed and deleted by the end of the test. The Tk root created in a
setUpX function should be destroyed in the corresponding tearDownX and
the module or class attribute deleted. Others widgets should descend
from the single root and the attributes deleted BEFORE root is
destroyed. See https://bugs.python.org/issue20567.
@classmethod
def setUpClass(cls):
requires('gui')
cls.root = tk.Tk()
cls.text = tk.Text(root)
@classmethod
def tearDownClass(cls):
del cls.text
cls.root.update_idletasks()
cls.root.destroy()
del cls.root
The update_idletasks call is sometimes needed to prevent the following
warning either when running a test alone or as part of the test suite
(#27196). It should not hurt if not needed.
can't invoke "event" command: application has been destroyed
...
"ttk::ThemeChanged"
If a test creates instance 'e' of EditorWindow, call 'e._close()' before
or as the first part of teardown. The effect of omitting this depends
on the later shutdown. Then enable the after_cancel loop in the
template. This prevents messages like the following.
bgerror failed to handle background error.
Original error: invalid command name "106096696timer_event"
Error in bgerror: can't invoke "tk" command: application has been destroyed
Requires('gui') causes the test(s) it guards to be skipped if any of
these conditions are met:
- The tests are being run by regrtest.py, and it was started without
enabling the "gui" resource with the "-u" command line option.
- The tests are being run on Windows by a service that is not allowed
to interact with the graphical environment.
- The tests are being run on Linux and X Windows is not available.
- The tests are being run on Mac OSX in a process that cannot make a
window manager connection.
- tkinter.Tk cannot be successfully instantiated for some reason.
- test.support.use_resources has been set by something other than
regrtest.py and does not contain "gui".
Tests of non-GUI operations should avoid creating tk widgets. Incidental
uses of tk variables and messageboxes can be replaced by the mock
classes in idle_test/mock_tk.py. The mock text handles some uses of the
tk Text widget.
3. Running Unit Tests
Assume that xyz.py and test_xyz.py both end with a unittest.main() call.
Running either from an Idle editor runs all tests in the test_xyz file
with the version of Python running Idle. Test output appears in the
Shell window. The 'verbosity=2' option lists all test methods in the
file, which is appropriate when developing tests. The 'exit=False'
option is needed in xyx.py files when an htest follows.
The following command lines also run all test methods, including
GUI tests, in test_xyz.py. (Both '-m idlelib' and '-m idlelib.idle'
start Idle and so cannot run tests.)
python -m idlelib.xyz
python -m idlelib.idle_test.test_xyz
The following runs all idle_test/test_*.py tests interactively.
>>> import unittest
>>> unittest.main('idlelib.idle_test', verbosity=2)
The following run all Idle tests at a command line. Option '-v' is the
same as 'verbosity=2'.
python -m unittest -v idlelib.idle_test
python -m test -v -ugui test_idle
python -m test.test_idle
The idle tests are 'discovered' by
idlelib.idle_test.__init__.load_tests, which is also imported into
test.test_idle. Normally, neither file should be changed when working on
individual test modules. The third command runs unittest indirectly
through regrtest. The same happens when the entire test suite is run
with 'python -m test'. So that command must work for buildbots to stay
green. Idle tests must not disturb the environment in a way that makes
other tests fail (issue 18081).
To run an individual Testcase or test method, extend the dotted name
given to unittest on the command line or use the test -m option. The
latter allows use of other regrtest options. When using the latter,
all components of the pattern must be present, but any can be replaced
by '*'.
python -m unittest -v idlelib.idle_test.test_xyz.Test_case.test_meth
python -m test -m idlelib.idle_test.text_xyz.Test_case.test_meth test_idle
The test suite can be run in an IDLE user process from Shell.
>>> import test.autotest # Issue 25588, 2017/10/13, 3.6.4, 3.7.0a2.
There are currently failures not usually present, and this does not
work when run from the editor.
4. Human-mediated Tests
Human-mediated tests are widget tests that cannot be automated but need
human verification. They are contained in idlelib/idle_test/htest.py,
which has instructions. (Some modules need an auxiliary function,
identified with "# htest # on the header line.) The set is about
complete, though some tests need improvement. To run all htests, run the
htest file from an editor or from the command line with:
python -m idlelib.idle_test.htest
5. Test Coverage
Install the coverage package into your Python 3.6 site-packages
directory. (Its exact location depends on the OS).
> python3 -m pip install coverage
(On Windows, replace 'python3 with 'py -3.6' or perhaps just 'python'.)
The problem with running coverage with repository python is that
coverage uses absolute imports for its submodules, hence it needs to be
in a directory in sys.path. One solution: copy the package to the
directory containing the cpython repository. Call it 'dev'. Then run
coverage either directly or from a script in that directory so that
'dev' is prepended to sys.path.
Either edit or add dev/.coveragerc so it looks something like this.
---
# .coveragerc sets coverage options.
[run]
branch = True
[report]
# Regexes for lines to exclude from consideration
exclude_lines =
# Don't complain if non-runnable code isn't run:
if 0:
if __name__ == .__main__.:
.*# htest #
if not _utest:
if _htest:
---
The additions for IDLE are 'branch = True', to test coverage both ways,
and the last three exclude lines, to exclude things peculiar to IDLE
that are not executed during tests.
A script like the following cover.bat (for Windows) is very handy.
---
@echo off
rem Usage: cover filename [test_ suffix] # proper case required by coverage
rem filename without .py, 2nd parameter if test is not test_filename

The second parameter was added for tests of module x not named test_x.

Create a master Tk window. Within that, run each callable in tests

In a tested module, let X be a global name bound to a callable (class

The first parameter of X must be 'parent'. When called, the parent
argument will be the root window. X must create a child Toplevel
window (or subclass thereof). The Toplevel may be a test widget or
dialog, in which case the callable is the corresonding class. Or the
Toplevel may contain the widget to be tested or set up a context in
which a test widget is invoked. In this latter case, the callable is a
wrapper function that sets up the Toplevel and other objects. Wrapper
function names, such as _editor_window', should start with '_'.
