Useful operators for defining functions in an applicative context

Documentation

(%) :: (a -> b) -> a -> b infixr 5

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

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

Functional composition for applicative functors.

(>*>) :: Applicative f => f (a -> b) -> f (b -> c) -> f (a -> c) infixr 4

Functional composition for applicative functors with its arguments flipped.

(<$<) :: Functor f => (b -> c) -> f (a -> b) -> f (a -> c) infixr 4

Applicative functional composition between a pure function and an applicative function.

(>$>) :: Functor f => f (a -> b) -> (b -> c) -> f (a -> c) infixr 4

Applicative functional composition between a pure function and an applicative function with its arguments flipped.
