This package contains instances for types in GHC boot libraries. For some additional instances see [indexed-traversable-instances](https://hackage.haskell.org/package/indexed-traversable-instances). . The [keys](https://hackage.haskell.org/package/keys) package provides similar functionality, but uses (associated) @TypeFamilies@ instead of @FunctionalDependencies@. extra-source-files: Changelog.md tested-with: GHC ==7.0.4 || ==7.2.2 || ==7.4.2 || ==7.6.3 || ==7.8.4 || ==7.10.3 || ==8.0.2 || ==8.2.2 || ==8.4.4 || ==8.6.5 || ==8.8.4 || ==8.10.7 || ==9.0.2 || ==9.2.4 || ==9.4.1 source-repository head type: git location: https://github.com/haskellari/indexed-traversable subdir: indexed-traversable library default-language: Haskell2010 ghc-options: -Wall hs-source-dirs: src other-modules: GhcExts WithIndex exposed-modules: Data.Foldable.WithIndex Data.Functor.WithIndex Data.Traversable.WithIndex build-depends: array >=0.3.0.2 && <0.6 , base >=4.3 && <4.18 , containers >=0.4.0.0 && <0.7 , transformers >=0.3.0.0 && <0.7 if !impl(ghc >=7.8) build-depends: tagged >=0.8.5 && <0.9 if !impl(ghc >=7.10) build-depends: void >=0.7.2 && <0.8 if !impl(ghc >=8.0) build-depends: base-orphans >=0.8.3 && <0.9 , semigroups >=0.18.4 && <0.21 , transformers-compat >=0.6.6 && <0.8 if (impl(ghc >=7.0) && impl(ghc <7.6)) build-depends: ghc-prim if (impl(ghc >=7.0) && impl(ghc <7.2)) build-depends: generic-deriving ==1.14.*
