Description:
Haskell support for regexp based pattern matching; profiling libraries
HaRP, or Haskell Regular Patterns, is a Haskell extension that extends the normal pattern matching facility, allowing the user to match against 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. HaRP is implemented as a pre-processor to ordinary Haskell. . This package provides a library for the Haskell programming language, compiled for profiling. See http://www.haskell.org/ for more information on Haskell.
