version: 0.6
synopsis: Backports of GHC deriving extensions
description: Provides Template Haskell functions that mimic deriving
extensions that were introduced or modified in recent versions
of GHC. Currently, the following typeclasses/extensions are covered:
.
* Deriving @Bounded@
.
* Deriving @Enum@
.
* Deriving @Ix@
.
* Deriving @Eq@, @Eq1@, and @Eq2@
.
* Deriving @Ord@, @Ord1@, and @Ord2@
.
* Deriving @Read@, @Read1@, and @Read2@
.
* Deriving @Show@, @Show1@, and @Show2@
.
* @DeriveFoldable@
.
* @DeriveFunctor@
.
* @DeriveTraversable@
.
* @GeneralizedNewtypeDeriving@ (with GHC 8.2 or later)
.
* @DerivingVia@ (with GHC 8.2 or later)
.
See the "Data.Deriving" module for a full list of backported changes.
.
Note that some recent GHC typeclasses/extensions are not covered by this package:
.
* @DeriveDataTypeable@
.
* @DeriveGeneric@, which was introducted in GHC 7.2 for deriving
@Generic@ instances, and modified in GHC 7.6 to allow derivation
of @Generic1@ instances. Use @Generics.Deriving.TH@ from
@<http://hackage.haskell.org/package/generic-deriving generic-deriving>@
to derive @Generic(1)@ using Template Haskell.
.
* @DeriveLift@, which was introduced in GHC 8.0 for deriving
@Lift@ instances. Use @Language.Haskell.TH.Lift@ from
@<http://hackage.haskell.org/package/th-lift th-lift>@
to derive @Lift@ using Template Haskell.
.
* The @Bifunctor@ typeclass, which was introduced in GHC 7.10,
as well as the @Bifoldable@ and @Bitraversable@ typeclasses, which
were introduced in GHC 8.2. Use @Data.Bifunctor.TH@ from
@<http://hackage.haskell.org/package/bifunctors bifunctors>@
to derive these typeclasses using Template Haskell.
