Re: Multiline pattern matching

[blue_cowdawg]

Base Assumption: Your text you are trying to match is somehow in one single variable.

$str =~ m/foo\{(.*)\}\;/;

$1 is now going to contain everything between the curly braces. The flaw I see in my own pattern matching is the fact that if you have another "};" along the way you might not have what you are after.

Then again.. you were pretty vague about your specifications... ;-)

Sorry, blue_cowdawg, you do a common mistake: You used dot star - please read Death to Dot Star! which explains why you should never ever use it :-)

use signature; signature(" So long\nAlfie");

Your Death to Dot Star post is rather convincing!

I like merlyn's comment concerning inching along though. If I really had to write something to parse foo { ... }; I'd probably use that.

What I find really intriguing however is the original question posed however vague. Given a Perl'ish structure of text where you have a symbol followed by a open curly brace followed by more text with possibly more curly braces (open and closed) how do you go about matching the right pair?

My first instinct would be to look towards some sort of recursive parser and not a regex. What are your thoughts?
