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. � )� HyperParser)�idleConf�(�)�[�]�{�}�d c @ sH e Z d Z d Z d d1 g f g Z e j d d d d d �Z e j d d d d d d d �Z e j e j � d � Z e j d d d d d d d �Z d Z d2 Z d d � Z d d � Z d d � Z d d � Z d d � Z d d! � Z d" d# d$ � Z d% d& � Z d' d( � Z d) d* � Z d+ d, � Z d- d. � Z d/ d0 � Z d" S)3� ParenMatcha� 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.
