A lot of text I operate on, has two-dimensional regularity - eg. a box of
comments starting at some column.
However I see that there is no way to specify the connections in a column
across rows, and have rectangle operations on it. This is evident when I
hilit programs in x emacs, where boxed comments are highlited as single
sequence of chars.
Has anyone implemented anything like this? for emacs? Of course, the
regular-expression algorithm would need to re-examine the notion of
'next-char' in the list it is parsing.
Maybe this is related to picture/graph-grammars? Any pointers appreciated.
