File microlens.cabal of Package ghc-microlens
name: microlens version: 0.4.13.1 x-revision: 1 synopsis: A tiny lens library with no dependencies description: NOTE: If you're writing an app, you probably want <http://hackage.haskell.org/package/microlens-platform microlens-platform> – it has the most features. <http://hackage.haskell.org/package/microlens microlens> is intended more for library writers who want a tiny lens library (after all, lenses are pretty useful for everything, not just for updating records!). . This library is an extract from <http://hackage.haskell.org/package/lens lens> (with no dependencies). It's not a toy lenses library, unsuitable for “real world”, but merely a small one. It is compatible with lens, and should have same performance. It also has better documentation. . There's a longer readme <https://github.com/stevenfontanella/microlens#readme on Github>. It has a migration guide for lens users, a description of other packages in the family, a discussion of other lens libraries you could use instead, and so on. . Here are some usecases for this library: . * You want to define lenses or traversals in your own library, but don't want to depend on lens. Having lenses available often make working with a library more pleasant. . * You just want to be able to use lenses to transform data (or even just use @over _1@ to change the first element of a tuple). . * You are new to lenses and want a small library to play with. . However, don't use this library if: . * You need @Iso@s, @Prism@s, indexed traversals, or actually anything else which isn't defined here (though some indexed functions are available elsewhere – containers and vector provide them for their types, and <http://hackage.haskell.org/package/ilist ilist> provides indexed functions for lists). . * You want a library with a clean, understandable implementation (in which case you're looking for <http://hackage.haskell.org/package/lens-simple lens-simple>). . As already mentioned, if you're writing an application which uses lenses more extensively, look at <http://hackage.haskell.org/package/microlens-platform microlens-platform> – it combines features of most other microlens packages (<http://hackage.haskell.org/package/microlens-mtl microlens-mtl>, <http://hackage.haskell.org/package/microlens-th microlens-th>, <http://hackage.haskell.org/package/microlens-ghc microlens-ghc>). . If you want to export getters or folds and don't mind the <http://hackage.haskell.org/package/contravariant contravariant> dependency, please consider using <http://hackage.haskell.org/package/microlens-contra microlens-contra>. . If you haven't ever used lenses before, read <http://hackage.haskell.org/package/lens-tutorial/docs/Control-Lens-Tutorial.html this tutorial>. (It's for lens, but it applies to microlens just as well.) . Note that microlens has no dependencies starting from GHC 7.10 (base-4.8). Prior to that, it depends on transformers-0.2 or above. license: BSD3 license-file: LICENSE author: Edward Kmett, Artyom Kazak maintainer: Steven Fontanella <steven.fontanella@gmail.com> homepage: http://github.com/stevenfontanella/microlens bug-reports: http://github.com/stevenfontanella/microlens/issues -- copyright: category: Data, Lenses build-type: Simple extra-source-files: CHANGELOG.md cabal-version: >=1.10 tested-with: GHC==9.8.1 GHC==9.6.3 GHC==9.4.7 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 GHC==7.10.3 source-repository head type: git location: https://github.com/stevenfontanella/microlens.git library exposed-modules: Lens.Micro Lens.Micro.Extras Lens.Micro.Internal Lens.Micro.Type -- other-modules: -- other-extensions: -- Since base-4.8 we get the Identity functor in base, so we can avoid a -- transformers dependency. if impl(ghc>=7.9) build-depends: base >=4.8 && <5 if !impl(ghc>=7.9) build-depends: base >=4.5 && <5 , transformers >=0.2 ghc-options: -Wall -fwarn-tabs -O2 -fdicts-cheap -funbox-strict-fields -fmax-simplifier-iterations=10 hs-source-dirs: src default-language: Haskell2010 default-extensions: TypeOperators
