Hi all,

I need to handle a large number of regular expressions in a new Cocoa project, so I could use some advice on the best library to use on Jaguar (and eventually Panther). I need some advanced features like back-references, lookahead, etc., and I particularly need to handle UTF8 strings. So I can't use most basic implementations for regex. So far I found three large libraries, so if you have some details or experiences about them I'm interested:
- "regex" is isntalled by default on Mac OS X, but doesn't seem to handle UTF8: I don't know for sure, since the documentation (man page) is very sparse and confuse. Also it's an alpha version, so is it reliable?
- "pcre" is a well-known library, available via Fink. It does handle UTF8, but not the Unicode classes. Good documentation, but I don't know the performances.
- "perlembed" is also installed by default on Mac OS X, but looks complicated to use; and I don't really need the power of Perl, only regexes. Also I'm not sure if the interpreter will hurt the performances.

Also does anyone know if there are some nice Cocoa wrappers for all these C libraries?

Thanks for any advice,

Thomas Lachand-Robert
