-Name: fclabels-Version: 2.0.0.2-Author: Sebastiaan Visser, Erik Hesselink, Chris Eidhof, Sjoerd Visscher- with lots of help and feedback from others.-Synopsis: First class accessor labels implemented as lenses.-Description: This package provides first class labels that can act as- bidirectional record fields. The labels can be derived- automatically using Template Haskell which means you don't have- to write any boilerplate yourself. The labels are implemented as- /lenses/ and are fully composable. Lenses can be used to /get/,- /set/ and /modify/ parts of a data type in a consistent way.- .- See "Data.Label" for an introductory explanation or see the- introductory blog post at- <http://fvisser.nl/post/2013/okt/1/fclabels-2.0.html>- .- * /Total and partial lenses/- .- Internally lenses do not used Haskell functions directly, but- are implemented as categories. Categories allow the lenses to be- run in custom computational contexts. This approach allows us to- make partial lenses that point to fields of multi-constructor- datatypes in an elegant way.- .- See "Data.Label.Partial" for the use of partial labels.- .- * /Monomorphic and polymorphic lenses/- .- We have both polymorphic and monomorphic lenses. Polymorphic- lenses allow updates that change the type. The types of- polymorphic lenses are slightly more verbose than their- monomorphic counterparts, but their usage is similar. Because- monomorphic lenses are built by restricting the types of- polymorphic lenses they are essentially the same and can be- freely composed with eachother.- .- See "Data.Label.Mono" and "Data.Label.Poly" for the difference- between polymorphic and monomorphic lenses.- .- * /Using fclabels/- .- To simplify working with labels we supply both a set of labels- for Haskell's base types, like lists, tuples, Maybe and Either,- and we supply a set of combinators for working with labels for- values in the Reader and State monad.- .- See "Data.Label.Base" and "Data.Label.Monadic" for more- information.- .- * /Changelog from 2.0.0.1 to 2.0.0.2/- .- > - Fix deriving with data types with more than 24 fields.--Maintainer: Sebastiaan Visser <code@fvisser.nl>-Homepage: https://github.com/sebastiaanvisser/fclabels-Bug-Reports: http://github.com/sebastiaanvisser/fclabels/issues--License: BSD3-License-File: LICENSE-Category: Data, Lenses-Cabal-Version: >= 1.6-Build-Type: Simple--Library- HS-Source-Dirs: src-- Exposed-Modules:- Data.Label- Data.Label.Base- Data.Label.Derive- Data.Label.Failing- Data.Label.Monadic- Data.Label.Mono- Data.Label.Partial- Data.Label.Point- Data.Label.Poly- Data.Label.Total-- GHC-Options: -Wall- Build-Depends:- base < 5- , template-haskell >= 2.2 && < 2.9- , mtl >= 1.0 && < 2.2- , transformers >= 0.2 && < 0.4--Source-Repository head- Type: git- Location: git://github.com/sebastiaanvisser/fclabels.git-+Name: fclabels +Version: 2.0.0.2 +x-revision: 1 +Author: Sebastiaan Visser, Erik Hesselink, Chris Eidhof, Sjoerd Visscher + with lots of help and feedback from others. +Synopsis: First class accessor labels implemented as lenses. +Description: This package provides first class labels that can act as + bidirectional record fields.
