- ParenMatch
class ParenMatch |
| |
Highlight matching parentheses
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:
- 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.
