HaRP, or Haskell Regular Patterns, is a Haskell extension that extends the normal pattern matching facility with the power of regular expressions. This expressive power is highly useful in a wide range of areas, including text parsing and XML processing. Regular expression patterns in HaRP work over ordinary Haskell lists ([]) of arbitrary type. We have implemented HaRP as a pre-processor to ordinary Haskell. . This package also contains trhsx, the desugaring pre-processor executable for HaRP and HSP

haskell-src-exts (HSX, haskell-source with extensions) is an extension of the standard haskell-src package, and handles most common syntactic extensions to Haskell, including: * Multi-parameter type classes with functional dependencies * Empty data declarations * GADTs * Implicit parameters (ghc and hugs style) * Template Haskell (broken for 6.4, needs redoing)
