@hackage partial-semigroup0.5.1.1

A partial binary associative operator

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.

The partial-semigroup-hedgehog companion package provides support for checking the partial semigroup associativity axiom using the hedgehog package.

      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.

       (on by default)

      Use the hedgehog package for tests.

      Disabling this flag disables all of the tests that use hedgehog.
