Mac/IDLE/config-extensions.def

-# config-extensions.def
-#
-# IDLE reads several config files to determine user preferences.  This
-# file is the default configuration file for IDLE extensions settings.
-#
-# Each extension must have at least one section, named after the extension
-# module. This section must contain an 'enable' item (=1 to enable the
-# extension, =0 to disable it), it may contain 'enable_editor' or 'enable_shell'
-# items, to apply it only to editor/shell windows, and may also contain any
-# other general configuration items for the extension.
-#
-# Each extension must define at least one section named ExtensionName_bindings
-# or ExtensionName_cfgBindings. If present, ExtensionName_bindings defines
-# virtual event bindings for the extension that are not user re-configurable.
-# If present, ExtensionName_cfgBindings defines virtual event bindings for the
-# extension that may be sensibly re-configured.
-#
-# If there are no keybindings for a menus' virtual events, include lines like
-# <<toggle-code-context>>=   (See [CodeContext], below.)
-#
-# Currently it is necessary to manually modify this file to change extension
-# key bindings and default values. To customize, create
-# ~/.idlerc/config-extensions.cfg and append the appropriate customized
-# section(s).  Those sections will override the defaults in this file.
-#
-# Note: If a keybinding is already in use when the extension is
-# loaded, the extension's virtual event's keybinding will be set to ''.
-#
-# See config-keys.def for notes on specifying keys and extend.txt for
-# information on creating IDLE extensions.

Mac/IDLE/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
-#     ---------------------
-#     config-main.def         the default general config file
-#     config-extensions.def   the default extension config file
-#     config-highlight.def    the default highlighting config file
-#     config-keys.def         the default keybinding config file
-#
-#     user configuration
-#     -------------------
-#     ~/.idlerc/config-main.cfg            the user general config file
-#     ~/.idlerc/config-extensions.cfg      the user extension config file
-#     ~/.idlerc/config-highlight.cfg       the user highlighting config file
-#     ~/.idlerc/config-keys.cfg            the user keybinding config file
-#
-# On Windows2000 and Windows XP the .idlerc directory is at
-#     Documents and Settings\<username>\.idlerc
-#
-# On Windows98 it is at c:\.idlerc
-#
-# Any options the user saves through the config dialog will be saved to
-# the relevant user config file. Reverting any general setting to the
-# default causes that entry to be wiped from the user file and re-read
-# from the default file. User highlighting themes or keybinding sets 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 and must 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 is
-# <sequence_number = menu item;/path/to/help/source>
-# 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.
-#
-# It is best to use the Configuration GUI to set up additional help sources!
-# Example:
-#1 = My Extra Help Source;/usr/share/doc/foo/index.html
-#2 = Another Help Source;/path/to/another.pdf
