parser generator for Haskell

Happy is a parser generator for Haskell. Given a grammar specification in BNF, Happy generates Haskell code to parse the grammar. Happy works in a similar way to the yacc tool for C.

This library provides the following functionality:

  * Data type definitions for the Grammar AST type, capturing
    the information in .y-files (Happy.Grammar)

  * A parser for happy grammar files (.y) to produce a Grammar
    (Happy.Frontend.*)

  * Implementations of the text book algorithms that compute the
    LR action and goto tables for the given 'Grammar'
    (Happy.Tabular.*)

  * An LALR code generator to produce table-driven, deterministic
    parsing code in Haskell (Happy.Backend.LALR.*)

  * A (less maintained) GLR code generator to produce
    table-driven, non-deterministic parsing code in Haskell,
    where ambiguous parses produce multiple parse trees
    (Happy.Backend.GLR.*)

This package provides a library for the Haskell programming language. See http://www.haskell.org/ for more information on Haskell.
