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.*)

-- The workaround moves Paths_happy_lib into `tabular` where it can be shared.
