description:
  A partial semigroup is like a semigroup, but the operator is partial. We
  represent this in Haskell as a total function @(<>?) :: a -> a -> Maybe a@.

flag semigroup-in-base
  default: True
  description:
    Require a version of `base` that provides the `Data.Semigroup` and
    `Data.List.NonEmpty` modules.
    .
    Disabling this flag adds a dependency on the `semigroups` package.

flag identity-in-base
  default: True
  description:
    Require a version of `base` that provides the `Data.Functor.Identity`
    module.

flag generics-in-base
  default: True
  description:
    Require a version of `base` that provides the `GHC.Generics` module.
    .
    Disabling this flag removes the `Data.PartialSemigroup.Generics` module
    from the package.

flag enable-hedgehog
  default: True
  description:
    Use the `hedgehog` package for tests.
    .
    Disabling this flag disables all of the tests that use `hedgehog`.

flag enable-doctest
  default: True
  description:
    Use the `doctest` package to test the code examples in Haddock comments.
