This package provides functionality for generalising the deriving mechanism in
Haskell to arbitrary classes. It was first described in the paper:
* /A generic deriving mechanism for Haskell/. Jose Pedro Magalhaes, Atze
Dijkstra, Johan Jeuring, and Andres Loeh. Haskell'10.
The current implementation integrates with the new GHC Generics. See
<> for more information.
Template Haskell code is provided for supporting older GHCs.

- Update generic-deriving to version 1.12.3.
[#] 1.12.3 [2019.02.09]
* Support `template-haskell-2.15`.
* Add a `gshowList` method to `GShow`, which lets us avoid the need for
`OverlappingInstances` in `Generics.Deriving.TH`. As a consequence, the
`GShow String` instance has been removed, as it is now fully subsumed by
the `GShow [a]` instance (with which it previously overlapped).
* Functions in `Generics.Deriving.TH` now balance groups of `(:*:)` and `(:+:)`
as much as possible (`deriving Generic` was already performing this
optimization, and now `generic-deriving` does too).
* Add a `Generics.Deriving.Default` module demonstrating and explaining
how and why to use `DerivingVia`. There is also a test suite with
further examples.

- Update generic-deriving to version 1.12.2.
[#] 1.12.2 [2018.06.28]
* Backport the `Generic(1)` instances for `Data.Ord.Down`, introduced in
`base-4.12`. Add `GEq`, `GShow`, `GSemigroup`, `GMonoid`, `GFunctor`,
`GFoldable`, `GTraversable`, and `GCopoint` instances for `Down`.
* Refactor internals using `th-abstraction`.
* Adapt to `Maybe` moving to `GHC.Maybe` in GHC 8.6.
2018-05-14 -
- Update generic-deriving to version 1.12.1 revision 1.
* Adapt to the `EmptyDataDeriving` proposal (introduced in GHC 8.4):
* `Generics.Deriving.TH` now derives `to(1)` and `from(1)` implementations
for empty data types that are strict in the argument.
* Introduce an `EmptyCaseOptions` field to `Options` in
`Generics.Deriving.TH`, which controls whether generated `from(1)`/`to(1)`
implementations for empty data types should use the `EmptyCase` extension
or not (as is the case in GHC 8.4).
* Add `mkFrom0Options`, `mkFrom1Options`, `mkTo0Options`, and `mkTo1Options`
functions to `Generics.Deriving.TH`, which take `EmptyCaseOptions` as
* The backported instances for `V1` are now maximally lazy, as per
`EmptyDataDeriving`. (Previously, some instances would unnecessarily force
their argument, such as the `Eq` and `Ord` instances.)
* Add instances for `V1` in `Generics.Deriving.Copoint`, `.Eq`, `.Foldable`,
`.Functor`, `.Show`, and `.Traversable`.
* Remove the bitrotting `simplInstance` function from `Generics.Deriving.TH`.
