1. (<$>) :: Functor f => (a -> b) -> f a -> f b

   verset	Verset

   An infix synonym for fmap. The name of this operator is an allusion to $. Note the similarities between their types:

   ($)  ::              (a -> b) ->   a ->   b
   (<$>) :: Functor f => (a -> b) -> f a -> f b
   

   Whereas $ is function application, <$> is function application lifted over a Functor.

   Examples

   Convert from a Maybe Int to a Maybe String using show:

   >>> show <$> Nothing
   Nothing
   

   >>> show <$> Just 3
   Just "3"
   

   Convert from an Either Int Int to an Either Int String using show:

   >>> show <$> Left 17
   Left 17
   

   >>> show <$> Right 17
   Right "17"
   

   Double each element of a list:

   >>> (*2) <$> [1,2,3]
   [2,4,6]
   

   Apply even to the second element of a pair:

   >>> even <$> (2,2)
   (2,True)
   

2. (<<$>>) :: (Functor f, Functor g) => (a -> b) -> f (g a) -> f (g b)

   verset	Verset

   No documentation available.

3. (>$) :: Contravariant f => b -> f b -> f a

   verset	Verset

   Replace all locations in the output with the same value. The default definition is contramap . const, but this may be overridden with a more efficient version.

4. (>$$<) :: Contravariant f => f b -> (a -> b) -> f a

   verset	Verset

   This is an infix version of contramap with the arguments flipped.

5. (>$<) :: Contravariant f => (a -> b) -> f b -> f a

   verset	Verset

   This is an infix alias for contramap.

6. (<$$>) :: Doc -> Doc -> Doc

   wl-pprint	Text.PrettyPrint.Leijen

   The document (x <$$> y) concatenates document x and y with a linebreak in between. (infixr 5)

7. (<$>) :: Doc -> Doc -> Doc

   wl-pprint	Text.PrettyPrint.Leijen

   The document (x <$> y) concatenates document x and y with a line in between. (infixr 5)

8. (<$) :: Functor f => a -> f b -> f a

   xmonad-contrib	XMonad.Config.Prime

   Replace all locations in the input with the same value. The default definition is fmap . const, but this may be overridden with a more efficient version.

   Examples

   Perform a computation with Maybe and replace the result with a constant value if it is Just:

   >>> 'a' <$ Just 2
   Just 'a'
   
   >>> 'a' <$ Nothing
   Nothing
   

9. (<$>) :: Functor f => (a -> b) -> f a -> f b

   xmonad-contrib	XMonad.Config.Prime

   An infix synonym for fmap. The name of this operator is an allusion to $. Note the similarities between their types:

   ($)  ::              (a -> b) ->   a ->   b
   (<$>) :: Functor f => (a -> b) -> f a -> f b
   

   Whereas $ is function application, <$> is function application lifted over a Functor.

   Examples

   Convert from a Maybe Int to a Maybe String using show:

   >>> show <$> Nothing
   Nothing
   

   >>> show <$> Just 3
   Just "3"
   

   Convert from an Either Int Int to an Either Int String using show:

   >>> show <$> Left 17
   Left 17
   

   >>> show <$> Right 17
   Right "17"
   

   Double each element of a list:

   >>> (*2) <$> [1,2,3]
   [2,4,6]
   

   Apply even to the second element of a pair:

   >>> even <$> (2,2)
   (2,True)
   

10. (>-$) :: X Input -> X String -> X Input

    xmonad-contrib	XMonad.Util.Run

    Combine an input with an ordinary string.
