1. mapSomeBase :: (forall b . () => Path b t -> Path b t') -> SomeBase t -> SomeBase t'

   path	Path.Posix

   Helper to apply a function to the SomeBase object

   >>> mapSomeBase parent (Abs [absfile|/foo/bar/cow.moo|]) == Abs [absdir|"/foo/bar"|]
   

2. mapSomeBase :: (forall b . () => Path b t -> Path b t') -> SomeBase t -> SomeBase t'

   path	Path.Windows

   Helper to apply a function to the SomeBase object

   >>> mapSomeBase parent (Abs [absfile|/foo/bar/cow.moo|]) == Abs [absdir|"/foo/bar"|]
   

3. mapDict :: (a :- b) -> Dict a -> Dict b

   constraints	Data.Constraint

   Apply an entailment to a dictionary. From a category theoretic perspective Dict is a functor that maps from the category of constraints (with arrows in :-) to the category Hask of Haskell data types.

4. mapUrls :: UrlMap -> Application

   wai-extra	Network.Wai.UrlMap

   No documentation available.

5. mapException :: (Exception e1, Exception e2) => (e1 -> e2) -> a -> a

   lifted-base	Control.Exception.Lifted

   This function maps one exception into another as proposed in the paper "A semantics for imprecise exceptions".

6. mapItems :: (Item a -> Item b) -> SpecWith a -> SpecWith b

   hspec-core	Test.Hspec.Core.Extension.Spec

   No documentation available.

7. mapItems :: (Item () -> Item ()) -> [SpecTree] -> [SpecTree]

   hspec-core	Test.Hspec.Core.Extension.Tree

   No documentation available.

8. mapSubject :: (b -> a) -> SpecWith a -> SpecWith b

   hspec-core	Test.Hspec.Core.Hooks

   Modify the subject under test. Note that this resembles a contravariant functor on the first type parameter of SpecM. This is because the subject is passed inwards, as an argument to the spec item.

9. mapSpecForest :: ([SpecTree a] -> [SpecTree b]) -> SpecM a r -> SpecM b r

   hspec-core	Test.Hspec.Core.Spec

   No documentation available.

10. mapSpecItem :: (ActionWith a -> ActionWith b) -> (Item a -> Item b) -> SpecWith a -> SpecWith b

    hspec-core	Test.Hspec.Core.Spec

    Deprecated: Use mapSpecItem_ instead.
