name: focus version: 1.0.3 synopsis: A general abstraction for manipulating elements of container data structures description: An API for construction of free-form strategies of access and manipulation of elements of arbitrary data structures. It allows to implement efficient composite patterns, e.g., a simultaneous update and lookup of an element, and even more complex things. . Strategies are meant to be interpreted by the host data structure libraries. Thus they allow to implement all access and modification patterns of a data structure with just a single function, which interprets strategies. . This library provides pure and monadic interfaces, so it supports both immutable and mutable data structures. category: Containers, Data homepage: https://github.com/nikita-volkov/focus bug-reports: https://github.com/nikita-volkov/focus/issues author: Nikita Volkov maintainer: Nikita Volkov copyright: (c) 2014, Nikita Volkov license: MIT license-file: LICENSE build-type: Simple cabal-version: >=1.10 source-repository head type: git location: git://github.com/nikita-volkov/focus.git library hs-source-dirs: library default-extensions: Arrows, BangPatterns, ConstraintKinds, DataKinds, DefaultSignatures, DeriveDataTypeable, DeriveFoldable, DeriveFunctor, DeriveGeneric, DeriveTraversable, EmptyDataDecls, FlexibleContexts, FlexibleInstances, FunctionalDependencies, GADTs, GeneralizedNewtypeDeriving, LambdaCase, LiberalTypeSynonyms, MagicHash, MultiParamTypeClasses, MultiWayIf, NoImplicitPrelude, NoMonomorphismRestriction, OverloadedLists, OverloadedStrings, PatternGuards, PatternSynonyms, ParallelListComp, QuasiQuotes, RankNTypes, RecordWildCards, ScopedTypeVariables, StandaloneDeriving, TemplateHaskell, TupleSections, TypeApplications, TypeFamilies, TypeOperators, UnboxedTuples default-language: Haskell2010 exposed-modules: Focus other-modules: Focus.Prelude build-depends: base >=4.11 && <5, transformers >=0.5 && <0.6 test-suite test type: exitcode-stdio-1.0 hs-source-dirs: test default-extensions: BangPatterns, DeriveDataTypeable, DeriveGeneric, DeriveFunctor, DeriveTraversable, FlexibleContexts, FlexibleInstances, LambdaCase, NoImplicitPrelude, RankNTypes, ScopedTypeVariables, StandaloneDeriving, TypeApplications, TypeFamilies default-language: Haskell2010 main-is: Main.hs build-depends: focus, QuickCheck >=2.8.1 && <3, quickcheck-instances >=0.3.11 && <0.4, rerebase <2, tasty >=0.12 && <2, tasty-hunit >=0.9 && <0.11, tasty-quickcheck >=0.9 && <0.11
