Re: Regex Start Anchor with variables

Hey guys,
Thx for that. Most examples use hardcoded regexes (for ease of reading I guess), so I couldn't figure it out.
Looks like \Q was what I needed.

`\Q` or `quotemeta` is indeed what you needed. But your problem is not connected with hardcoded regexes vs. regexes in variables. As Samy_rio correctly pointed out, the problem comes from the fact that '.' has a special meaning in a regex which you don't want in your case. Therefore you need to escape it: either by putting a '\' in front of it - which works fine for the hardcoded case an is a bit more complicated for variables OR you use `quotemeta` resp. `\Q` which works in both cases. -- Hofmator Code written by Hofmator and posted on PerlMonks is public domain.
