Basic Functions

val (|>) : 'a -> ('a -> 'b) -> 'b

Pipeline. x |> f is the same as f x.

val compose : ('a -> 'b) -> ('b -> 'c) -> 'a -> 'c

Composition

val compose_binop : ('a -> 'b) -> ('b -> 'b -> 'c) -> 'a -> 'a -> 'c

compose_binop f g is fun x y -> g (f x) (f y) Example (partial order): List.sort (compose_binop fst CCInt.compare) [1, true; 2, false; 1, false]

since 0.6

val (%>) : ('a -> 'b) -> ('b -> 'c) -> 'a -> 'c

Alias to compose

val (@@) : ('a -> 'b) -> 'a -> 'b

f @@ x is the same as f x, but right-associative.

since 0.5

val id : 'a -> 'a

Identity function

val const : 'a -> 'b -> 'a

const x y = x for any y

val flip : ('a -> 'b -> 'c) -> 'b -> 'a -> 'c

flip arguments

val curry : (('a * 'b) -> 'c) -> 'a -> 'b -> 'c

val uncurry : ('a -> 'b -> 'c) -> ('a * 'b) -> 'c

val tap : ('a -> 'b) -> 'a -> 'a

tap f x evaluates f x, discards it, then returns x. Useful in a pipeline, for instance:

CCArray.(1 -- 10)
|> tap CCArray.shuffle
|> tap CCArray.sort Pervasives.compare

val (%) : ('b -> 'c) -> ('a -> 'b) -> 'a -> 'c

Mathematical composition

val lexicographic : ('a -> 'a -> int) -> ('a -> 'a -> int) -> 'a -> 'a -> int

Lexicographic combination of comparison functions

val finally : h:(unit -> unit) -> f:(unit -> 'a) -> 'a

finally h f calls f () and returns its result. If it raises, the same exception is raised; in any case, h () is called after f () terminates.

Monad

functions with a fixed domain are monads in their codomain

module Monad (X : sig ... end) : sig ... end
