Subject: [9fans] non greedy regular expressions
Date: Thu, 23 Oct 2008 20:58:20 +0200	[thread overview]
Message-ID: <a560a5d00810231158p35a7c225i1e0f658910a99c85@mail.gmail.com> (raw)

Hello

regexp(6) seems to know only greedy regular expressions. So does
probably awk, sed, grep, ..., since these are based on that regexp.
My question is what to do if one needs non-greedy regexps.

Also, is there anything like submatch extraction, counted repetition
of regexp (like {3,5}), (lookahead) assertions in plan9?

Thanks
Ruda
