‚=5Dc @ sb d Z d k Z d k l Z l Z d k l Z d f d „ ƒ YZ d „ Z d f d „ ƒ YZ d S( sæ ParenMatch -- An IDLE extension for parenthesis matching.
When you hit a right paren, the cursor should move briefly to the left
paren. Paren here is used generically; the matching applies to
parentheses, square brackets, and curly braces.
WARNING: This extension will fight with the CallTips extension,
because they both are interested in the KeyRelease-parenright event.
We'll have to fix IDLE to do something reasonable when two or more
extensions what to capture the same event.

There are three supported style of paren matching, based loosely
on the Emacs options. The style is select based on the
HILITE_STYLE attribute; it can be changed used the set_style
method.
The supported styles are:
default -- When a right paren is typed, highlight the matching
left paren for 1/2 sec.
expression -- When a right paren is typed, highlight the entire
expression from the left paren to the right paren.
TODO:
- fix interaction with CallTips
- extend IDLE with configuration dialog to change options
- implement rest of Emacs highlight styles (see below)
- print mismatch warning in IDLE status window
Note: In Emacs, there are several styles of highlight where the
matching paren is highlighted whenever the cursor is immediately
to the right of a right paren. I don't know how to do that in Tk,
so I haven't bothered.
