http://hackage.haskell.org/package/rex Provides a quasi-quoter for regular expressions which yields a tuple, of appropriate arity and types, representing the results of the captures. Allows the user to specify parsers for captures as inline Haskell. Can also be used to provide typeful pattern matching in function definitions and case patterns. To build / install: ./Setup.hs configure --user ./Setup.hs build ./Setup.hs install See the haddock or Text/Regex/PCRE/QQT.hs for documentation.
