class (Functor (m t), Functor (m u), Functor (m v)) => PApplicative m t u v | t u -> v where

Parameterized version of ap in Applicative NB. PPointed cannot be made a superclass because type variable id is not in scope.

papply

Methods

papply :: m t (a -> b) -> m u a -> m v b

Sequential application.

Instances

(Monad m, Select a c, Select b c, Amend a c, Amend b c, (~) [Type] c (AppendUnique Type a b)) => PApplicative * (ManyState m) (Many a) (Many b) (Many c)

Methods

papply :: Many a (Many b) (a -> b) -> Many a (Many c) a -> Many a v b

Monad m => PApplicative * (ChangingState m) (s, t) (t, u) (s, u)

Methods

papply :: (s, t) (t, u) (a -> b) -> (s, t) (s, u) a -> (s, t) v b

(&<*>) :: PApplicative m t u v => m t (a -> b) -> m u a -> m v b infixl 4

Sequential application.

(&*>) :: PApplicative m t u v => m t a -> m u b -> m v b infixl 4

Sequence actions, discarding the value of the first argument.

(&<*) :: PApplicative m t u v => m t a -> m u b -> m v a infixl 4

Sequence actions, discarding the value of the second argument.

pliftA :: Functor (m t) => (a -> b) -> m t a -> m t b

Lift a function to actions.

pliftA2 :: PApplicative m t u v => (a -> b -> c) -> m t a -> m u b -> m v c

Lift a binary function to actions.

pliftA3 :: (PApplicative m t u v, PApplicative m v w x) => (a -> b -> c -> d) -> m t a -> m u b -> m w c -> m x d

Lift a ternary function to actions.

class PEmpty m id | m -> id where

Parameterized version of empty in Alternative. An instance of this should create a parameterized unary type where the parameter is an identity in respect to pappend

Minimal complete definition

pempty

Methods

pempty :: m id a

The identity of &<|>

Instances

Alternative m => PEmpty * (ManyReader m) (Many ([] Type))

Methods

pempty :: Many [Type] id a

Alternative m => PEmpty * (DistinctWhichReader m) (Which ([] Type))

Methods

pempty :: Which [Type] id a

Alternative m => PEmpty * (OverlappingWhichReader m) (Which ([] Type))

Methods

pempty :: Which [Type] id a

Alternative m => PEmpty * (ManyState m) (Many ([] Type))

Methods

pempty :: Many [Type] id a

class PAlternative m t u v | t u -> v where

Parameterized version of Alternative NB. PEmpty cannot be made a superclass because type variable id will be ambiguous. NB. PAlternative doensn't require PApplicative as a superclass, because Some things can be made instances of PAlternative but not PApplicative.
