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).
