Description
Useful operators for defining functions in an applicative context
Synopsis
- (%) :: (a -> b) -> a -> b
- (×) :: (a -> b) -> a -> b
- (<*<) :: Applicative f => f (b -> c) -> f (a -> b) -> f (a -> c)
- (>*>) :: Applicative f => f (a -> b) -> f (b -> c) -> f (a -> c)
- (<$<) :: Functor f => (b -> c) -> f (a -> b) -> f (a -> c)
- (>$>) :: Functor f => f (a -> b) -> (b -> c) -> f (a -> c)
Documentation
(%) :: (a -> b) -> a -> b infixr 5 Source #
This operator is an alternative for $ with a higher precedence. It is
suitable for usage within applicative style code without the need to add
parenthesis.
(×) :: (a -> b) -> a -> b infixr 5 Source #
Deprecated: use % instead
This operator is a UTF-8 version of % which is an alternative for $
with a higher precedence. It is suitable for usage within applicative style
code without the need to add parenthesis.
The hex value of the UTF-8 character × is 0x00d7.
In VIM type: Ctrl-V u 00d7
You may also define a key binding by adding something like the following line to your vim configuration file:
iabbrev <buffer> >< ×
(<*<) :: Applicative f => f (b -> c) -> f (a -> b) -> f (a -> c) infixr 4 Source #
Functional composition for applicative functors.
(>*>) :: Applicative f => f (a -> b) -> f (b -> c) -> f (a -> c) infixr 4 Source #
Functional composition for applicative functors with its arguments flipped.
