Re: Re: Re: More Variable length regex issues

Thanks for that. So the answer is, don't use square brackets as delimiters if the regex contains (unbalanced) square brackets.

It's a shame that there aren't a couple more sets of balanced brackets in the arsenal:) Preferably a pair that could be used soley for quote-like delimiting. Maybe now we have unicode, we could find a pairing that wouldn't get overloaded for 7 other things too? Some chance I think:)

Well, there are the French/German style quotes that look like << and >>... but Perl 6 uses them (believe it or not!). You can't use anything other than paren, bracket, brace, or angle-bracket in Perl right now to balance, since they're hardcoded into the parser/tokenizer. But you could certainly choose some obscure unicode character that doesn't need balancing. Actually, if you could tell the parser to include a pair of your own, like ` and ', that'd be cool. _____________________________________________________ Jeff`[japhy]`Pinyan: Perl, regex, and perl hacker, who'd like a job (NYC-area) `s++=END;++y(;-P)}y js++=;shajsj<++y(p-q)}?print:??;`	[reply]
