Re: Re: Re: filtering folder path using regex.

The question to ask yourself is: Is it incorrect? The answer is no.

perlre says "? Match 1 or 0 times", which means optional (like YAPE::Regex::Explain says).

Now, the extra "(matching the most amount possible)" comment may seem a bit misleading, but it's not wrong. Consider the re-pattern f?. It means match "f" optionally. Since "f" is fixed with, it'll always match the most amount possible. This may seem a bit silly, and may or may not be an unintended sideeffect of how YAPE::Regex::Explain works, but it's perfectly fine by me (if it is unintended, I don't think it's worth a workaround, if it's not, there is no issue).

It all comes down to interpretation and assumption. I just prefer explanations to be clear rather than a bit jagged at the edges. Anything that is open to misinterpretation most likely will be. If it works for you, thats fine. But it's worth bearing in mind that anyone new to the module may get mixed messages. -- Barbie \| Birmingham Perl Mongers \| http://birmingham.pm.org/	[reply]
