flip f takes its (first) two arguments in the reverse order of f.

flip f x y = f y x

flip . flip = id

Examples

>>> flip (++) "hello" "world"
"worldhello"

>>> let (.>) = flip (.) in (+1) .> show $ 5
"6"

flip f takes its (first) two arguments in the reverse order of f.

>>> flip (++) "hello" "world"
"worldhello"

Convenience function for supplying arguments to client functions when working with records of clients. Intended to be used in conjunction with (//). Example:

type Api = NamedRoutes RootApi

data RootApi mode = RootApi
{ subApi :: mode :- Capture "token" String :> NamedRoutes SubApi
, hello :: mode :- Capture "name" String :> Get '[JSON] String
, …
} deriving Generic

data SubApi mode = SubApi
{ endpoint :: mode :- Get '[JSON] Person
, …
} deriving Generic

api :: Proxy API
api = Proxy

rootClient :: RootApi (AsClientT ClientM)
rootClient = client api

hello :: String -> ClientM String
hello name = rootClient // hello /: name

endpointClient :: ClientM Person
endpointClient = client // subApi /: "foobar123" // endpoint

Backwards function application. This is an infix synonym for flip

Strict variant of flip. Defined as:

flip f b a = f $! a $! b

Since version 0.11.0.0.

Takes two lists and combines them with a custom combining function
