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.*) tested-with: GHC == 9.10.1 GHC == 9.8.2 GHC == 9.6.5 GHC == 9.4.8 GHC == 9.2.8 GHC == 9.0.2 GHC == 8.10.7 GHC == 8.8.4 GHC == 8.6.5 GHC == 8.4.4 GHC == 8.2.2 GHC == 8.0.2 extra-doc-files: ChangeLog.md README.md extra-source-files: frontend/bootstrap.sh frontend/boot-src/Parser.ly frontend/boot-src/AttrGrammarParser.ly data-dir: data data-files: HappyTemplate.hs GLR_Base.hs GLR_Lib.hs source-repository head type: git location: https://github.com/haskell/happy.git common common-stanza default-language: Haskell98 default-extensions: CPP, MagicHash, FlexibleContexts, NamedFieldPuns ghc-options: -Wall -Wno-incomplete-uni-patterns library grammar import: common-stanza hs-source-dirs: grammar/src exposed-modules: Happy.Grammar build-depends: base < 5, array library frontend import: common-stanza hs-source-dirs: frontend/src exposed-modules: Happy.Frontend, Happy.Frontend.AbsSyn, Happy.Frontend.Mangler, Happy.Frontend.PrettyGrammar build-depends: base < 5, array, transformers, containers, mtl, grammar other-modules: Happy.Frontend.ParseMonad Happy.Frontend.ParseMonad.Class Happy.Frontend.Mangler.Monad Happy.Frontend.Parser Happy.Frontend.Lexer Happy.Frontend.ParamRules Happy.Frontend.AttrGrammar Happy.Frontend.AttrGrammar.Parser Happy.Frontend.AttrGrammar.Mangler library tabular import: common-stanza hs-source-dirs: tabular/src exposed-modules: Happy.Tabular, Happy.Tabular.First, Happy.Tabular.Info, Happy.Tabular.LALR, Happy.Tabular.NameSet build-depends: base < 5, array, containers, grammar library backend-lalr import: common-stanza hs-source-dirs: backend-lalr/src exposed-modules: Happy.Backend.LALR, Happy.Backend.LALR.ProduceCode build-depends: base < 5, array, grammar, tabular other-modules: Paths_happy_lib autogen-modules: Paths_happy_lib library backend-glr import: common-stanza hs-source-dirs: backend-glr/src exposed-modules: Happy.Backend.GLR, Happy.Backend.GLR.ProduceCode build-depends: base < 5, array, grammar, tabular other-modules: Paths_happy_lib autogen-modules: Paths_happy_lib library import: common-stanza reexported-modules: Happy.Grammar, Happy.Frontend, Happy.Frontend.AbsSyn, Happy.Frontend.Mangler, Happy.Frontend.PrettyGrammar, Happy.Tabular, Happy.Tabular.First, Happy.Tabular.Info, Happy.Tabular.LALR, Happy.Tabular.NameSet, Happy.Backend.LALR, Happy.Backend.LALR.ProduceCode, Happy.Backend.GLR, Happy.Backend.GLR.ProduceCode build-depends: base >= 4.9 && < 5, array >= 0.5, containers >= 0.4.2, transformers >= 0.5.6.2, mtl >= 2.2.1, -- NB: omit the `happy-lib:` prefix in happy-lib:grammar. -- Otherwise we unnecessarily break Cabal < 3.4 grammar, tabular, frontend, backend-lalr, backend-glr
