Subject: Performance tips when using regular expressions (regexps) in font-locking
Date: Wed, 21 Nov 2007 09:00:30 -0800 (PST) [thread overview]
Message-ID: <c8c3a44f-d3be-4e4e-a50a-8853aba5450a@b15g2000hsa.googlegroups.com> (raw)
I have enhanced my cc-mode with extra font-locking for assignments,
function calls, numerical literals, operators and even format strings
to the [sf]?printf-functions. The regular expressions describing these
context are quite complicated and as a result my cc-mode is no longer
as snappy as without my enhancement. Does any have any tips on how to
write regular expressions when performance is crucial? For example
should I use [:space:] instead of [ \t]? Should I post the code
aswell?
Thanks in advance,
Nordlöw
