deriving-compat: Backports of GHC deriving extensions

[ bsd3, compatibility, library ] [ Propose Tags ] [ Report a vulnerability ]

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 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 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 bifunctors to derive these typeclasses using Template Haskell.

Flags

Automatic Flags

Name	Description	Default
base-4-9	Use base-4.9 or later.	Enabled
template-haskell-2-11	Use template-haskell-2.11.0.0 or later.	Enabled
new-functor-classes	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.	Enabled

Use -f <flag> to enable a flag, or -f -<flag> to disable that flag. More info
