deriving-compat: Backports of GHC deriving extensions
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:
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:
DeriveGeneric, which was introducted in GHC 7.2 for deriving
Genericinstances, and modified in GHC 7.6 to allow derivation of
Generic(1)using Template Haskell.
DeriveLift, which was introduced in GHC 8.0 for deriving
Liftusing Template Haskell.
Bifunctortypeclass, which was introduced in GHC 7.10, as well as the
Bitraversabletypeclasses, which were introduced in GHC 8.2. Use
bifunctorsto derive these typeclasses using Template Haskell.

Use base-4.9 or later.
Use template-haskell-126.96.36.199 or later.
Use a version of transformers or transformers-compat with a modern-style Data.Functor.Classes module. This flag cannot be used when building with transformers-0.4, since it comes with a different version of Data.Functor.Classes.
Use -f <flag> to enable a flag, or -f -<flag> to disable that flag. More info

Note: This package has metadata revisions in the cabal description newer than included in the tarball. To unpack the package including the revisions, use 'cabal get'.
