Re: [Haskell-cafe] Haskell performance when it comes to regex?

Brandon Allbery allbery.b@gmail.com:

TDFA is pure Haskell and mostly exists for when you can't be certain that a faster C binding will support UTF8 (most POSIX regex implementations do not, and PCRE only does so if someone built it with UTF8 support). When it's usable, the C bindings will almost always be faster.

I think we are in agreement, though I would generally recommend TDFA, unless you need the highest performance (as in this case) or Perl-style REs. But then again I like my REs plain and simple (and Posix) and packages with as few external dependencies as possible. Chris
