Regexp Delimiters

Perl lets you use almost anything as a regular expression delimiter. It is usual to use punctuation of some sort, but characters that match /\w/ can be used provided there is white space between the operator and the delimiter: m X foo Xsmx compiles and matches 'foobar'. In the presence of use utf8; you can go wild.

A query on the Perl 5 Porters Mailing List (a.k.a. 'p5p') a few days ago asked for opinions about appropriating the colon (':') as a delimiter for modifiers to the regular expression operators. This got me wondering about what regular expression delimiters were actually in use.

I scratched that itch by plowing through my local Mini CPAN, running everything that looked like Perl through PPI, and checking anything that parsed to an object of one of the relevant classes. A summary of the results is appended.

Back in business with SDL_ttf

I suppose that I could trace the code, find where the function is failing; however, I took a punt. Sometimes, older versions of a package are better. Developers may start off with something that works, then they add more features and clever things.
