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 * A parser for happy grammar files (.y) to produce a Grammar * Implementations of the text book algorithms that compute the LR action and goto tables for the given Grammar * An LALR code generator to produce table-driven, deterministic parsing code in Haskell * A (less maintained) GLR code generator to produce table-driven, non-deterministic parsing code in Haskell, where ambiguous parses produce multiple parse trees
