README.txt: an index to idlelib files and the IDLE menu.

IDLE is Python's Integrated Development and Learning
Environment. The user documentation is part of the Library Reference and
is available in IDLE by selecting Help => IDLE Help. This README documents
idlelib for IDLE developers and curious users.

IDLELIB FILES lists files alphabetically by category,
with a short description of each.

IDLE MENU show the menu tree, annotated with the module
or module object that implements the corresponding function.

This file is descriptive, not prescriptive, and may have errors
and omissions and lag behind changes in idlelib.

IDLE MENUS
==========

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

OTHER TOPICS
============

Generally use PEP 8.

import statements
-----------------
Put imports at the top, unless there is a good reason otherwise.
PEP 8 says to group stdlib, 3rd-party dependencies, and package imports.
For idlelib, the groups are general stdlib, tkinter, and idlelib.
Sort modules within each group, except that tkinter.ttk follows tkinter.
Sort 'from idlelib import mod1' and 'from idlelib.mod2 import object'
together by module, ignoring within module objects.
Put 'import __main__' after other idlelib imports.

Imports only needed for testing are put not at the top but in an
htest function def or "if __name__ == '__main__'" clause.

Within module imports like "from idlelib.mod import class" may cause
circular imports to deadlock. Even without this, circular imports may
require at least one of the imports to be delayed until a function call.

What's New entries
------------------

Repository directory Doc/whatsnew/ has a file 3.n.rst for each 3.n
Python version. For the first entry in each file, add subsection
'IDLE and idlelib', in alphabetical position, to the 'Improved Modules'
section. For the rest of cpython, entries to 3.(n+1).rst begin with
the release of 3.n.0b1. For IDLE, entries for features backported from
'main' to '3.n' during its beta period do not got in 3.(n+1).rst. The
latter usually gets its first entry during the 3.n.0 candidate period
or after the 3.n.0 release.

When, as per PEP 434, feature changes are backported, entries are placed
in the 3.n.rst file *in the main branch* for each Python version n that
gets the backport. (Note: the format of entries have varied between
versions.) Add a line "New in 3.n maintenance releases." before the
first back-ported feature after 3.n.0 is released. Since each older
version file gets a different number of backports, it is easiest to
make a separate PR for each file and label it with the backports
needed.

Github repository and issues
----------------------------

The CPython repository is https://github.com/python/cpython. The
IDLE Issues listing is https://github.com/orgs/python/projects/31.
The main classification is by Topic, based on the IDLE menu. View the
topics list by clicking the [<]] button in the upper right.
