< tool > A dyslexic acronym for "A Yacc-like Haskell Parser generator".
An LALR1 grammar parser generator for Haskell . Happy is written in Haskell, uses a parser generated by itself, and can be compiled using ghc , hbc or gofer . Happy uses an implementation of monadic IO built on top of stream IO, but this should change when the Haskell 1.3 standard has been implemented.
Version: 0.9 (1996-02-28).
