Description
Useful operators for defining functions in an applicative context
- (%) :: (α -> β) -> α -> β
- (×) :: (α -> β) -> α -> β
- (<*<) :: Applicative φ => φ (β -> γ) -> φ (α -> β) -> φ (α -> γ)
- (>*>) :: Applicative φ => φ (α -> β) -> φ (β -> γ) -> φ (α -> γ)
- (<$<) :: Functor φ => (β -> γ) -> φ (α -> β) -> φ (α -> γ)
- (>$>) :: Functor φ => φ (α -> β) -> (β -> γ) -> φ (α -> γ)
- (<.>) :: Applicative φ => φ (β -> γ) -> φ (α -> β) -> φ (α -> γ)
- (⊙) :: Applicative φ => φ (β -> γ) -> φ (α -> β) -> φ (α -> γ)

(%) :: (α -> β) -> α -> β 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.
(×) :: (α -> β) -> α -> β infixr 5 Source
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 φ => φ (β -> γ) -> φ (α -> β) -> φ (α -> γ) infixr 4 Source
Functional composition for applicative functors.
(>*>) :: Applicative φ => φ (α -> β) -> φ (β -> γ) -> φ (α -> γ) infixr 4 Source
Functional composition for applicative functors with its arguments flipped.
(<$<) :: Functor φ => (β -> γ) -> φ (α -> β) -> φ (α -> γ) infixr 4 Source
Applicative functional composition between a pure function and an applicative function.
(>$>) :: Functor φ => φ (α -> β) -> (β -> γ) -> φ (α -> γ) infixr 4 Source
Applicative functional composition between a pure function and an applicative function with its arguments flipped.
(<.>) :: Applicative φ => φ (β -> γ) -> φ (α -> β) -> φ (α -> γ) infixr 4 Source
Deprecated: use <*< instead
Functional composition for applicative functors.
This is a rather popular operator. Due to conflicts (for instance with the lens package) it may have to be imported qualified.
(⊙) :: Applicative φ => φ (β -> γ) -> φ (α -> β) -> φ (α -> γ) infixr 4 Source
