Update to reflect the current status of the configuration system.
Extensions must still be configured manually and there is currently one set of extension key bindings for all platforms. Bring NEWS.txt up to date. Update CREDITS.txt and idlever.py for release. M NEWS.txt M config-extensions.def M extend.txt M help.txt M idlever.py

Writing an IDLE extension

the file config.txt; see below for details.
|

the file config-extensions.def. See below for details.
|

An IDLE extension is defined by a class. Methods of the class define

The extension class must not bind key events. Rather, it must define
|
||||
one or more virtual events, e.g. <<zoom-height>>, and corresponding
|
||||
methods, e.g. zoom_height_event(), and have one or more class (or instance)
|
||||
variables that define mappings between virtual events and key sequences,
|
||||
e.g. <Alt-F2>. When the extension is loaded, these key sequences will
|
||||
be bound to the corresponding virtual events, and the virtual events
|
||||
will be bound to the corresponding methods. (This indirection is done
|
||||
so that the key bindings can easily be changed, and so that other
|
||||
sources of virtual events can exist, such as menu entries.)
|
||||
The extension class must not directly bind Window Manager (e.g. X) events.
|
||||
Rather, it must define one or more virtual events, e.g. <<zoom-height>>, and
|
||||
corresponding methods, e.g. zoom_height_event(). The virtual events will be
|
||||
bound to the corresponding methods, and Window Manager events can then be bound
|

to the virtual events. (This indirection is done so that the key bindings can
|
||||
easily be changed, and so that other sources of virtual events can exist, such
|
||||
as menu entries.)
|
||||
|
||||
The following class or instance variables are used to define key
|
||||
bindings for virtual events:
|
||||
An extension can define menu entries. This is done with a class or instance
|
||||
variable named menudefs; it should be a list of pairs, where each pair is a
|
||||
menu name (lowercase) and a list of menu entries. Each menu entry is either
|
||||
None (to insert a separator entry) or a pair of strings (menu_label,
|
||||
virtual_event). Here, menu_label is the label of the menu entry, and
|
||||
virtual_event is the virtual event to be generated when the entry is selected.
|
||||
An underscore in the menu label is removed; the character following the
|
||||
underscore is displayed underlined, to indicate the shortcut character (for
|
||||
Windows).
|

|

keydefs for all platforms
|
||||
mac_keydefs for Macintosh
|
||||
windows_keydefs for Windows
|
||||
unix_keydefs for Unix (and other platforms)
|
||||
At the moment, extensions cannot define whole new menus; they must define
|
||||
entries in existing menus. Some menus are not present on some windows; such
|
||||
entry definitions are then ignored, but key bindings are still applied. (This
|
||||
should probably be refined in the future.)
|
||||
|
||||
Each of these variables, if it exists, must be a dictionary whose
|
||||
keys are virtual events, and whose values are lists of key sequences.
|
||||
|
||||
An extension can define menu entries in a similar fashion. This is done
|
||||
with a class or instance variable named menudefs; it should be a list of
|
||||
pair, where each pair is a menu name (lowercase) and a list of menu
|
||||
entries. Each menu entry is either None (to insert a separator entry) or
|
||||
a pair of strings (menu_label, virtual_event). Here, menu_label is the
|
||||
label of the menu entry, and virtual_event is the virtual event to be
|
||||
generated when the entry is selected. An underscore in the menu label
|
||||
is removed; the character following the underscore is displayed
|
||||
underlined, to indicate the shortcut character (for Windows).

||||
At the moment, extensions cannot define whole new menus; they must
|
||||
define entries in existing menus. Some menus are not present on some
|
||||
windows; such entry definitions are then ignored, but the key bindings
|
||||
are still applied. (This should probably be refined in the future.)
|
||||
Extensions are not required to define menu entries for all the events they
|
||||
implement. (XXX KBK 15Jul03: But it appears they must have keybindings for each
|
||||
virtual event?)

The final piece of the puzzle is the file "config.txt", which is used
|
||||
to to configure the loading of extensions. For each extension,
|
||||
you must include a section in config.txt (or in any of the other
|
||||
configuration files that are consulted at startup: config-unix.txt,
|
||||
config-win.txt, or ~/.idle). A section is headed by the module name
|
||||
in square brackets, e.g.
|
||||
The final piece of the puzzle is the file "config-extensions.def", which is
|

used to to configure the loading of extensions and to establish key (or, more
|
||||
generally, event) bindings to the virtual events defined in the extensions.
|
||||
|
||||
[ZoomHeight]
|
||||
See the comments at the top of config-extensions.def for information. It's
|
||||
currently necessary to manually modify that file to change IDLE's extension
|
||||
loading or extension key bindings.
|
||||
|
||||
The section may be empty, or it may define configuration options for
|
||||
the extension. (See ParenMatch.py for an example.) A special option
|
||||
is 'enable': including
|
||||
|
||||
enable = 0
|
||||
|
||||
in a section disables that extension. More than one configuration
|
||||
file may specify options for the same extension, so a user may disable
|
||||
an extension that is loaded by default, or enable an extension that is
|
||||
disabled by default.
|
||||
|
||||
Extensions can define key bindings and menu entries that reference
|
||||
events they don't implement (including standard events); however this is
|
||||
not recommended (and may be forbidden in the future).
|
||||
|
||||
Extensions are not required to define menu entries for all events they
|
||||
implement.
|
||||
|
||||
Note: in order to change key bindings, you must currently edit the file
|
||||
keydefs. It contains two dictionaries named and formatted like the
|
||||
keydefs dictionaries described above, one for the Unix bindings and one
|
||||
for the Windows bindings. In the future, a better mechanism will be
|
||||
provided.
|
||||

|
||||
python.org and to the Tk Command "bind" man page.
