synopsis: Happy is a parser generator for Haskell implemented using this library
category: Development
build-type: Simple

Description:
  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.*)
