Module Utils.MiscSource

Several useful types and functions

Sourcetype ('a, 'b) either =
  1. | Fst of 'a
  2. | Snd of 'b
  3. | Both of 'a * 'b
Sourceval log2 : int -> int
Sourceval time_of_day : unit -> string
Sourceval flip : ('a -> 'b -> 'c) -> 'b -> 'a -> 'c

flip f x y is f y x

Sourceval id : 'a -> 'a

id x is x

Sourceval max : 'a -> 'a -> 'a
Sourceval min : 'a -> 'a -> 'a
Sourceval iter_fix : ('a -> 'a -> bool) -> ('a -> 'a) -> 'a -> 'a

iter_fix eq f x iterates f, starting with x, until idempotence, i.e. computes f (f (f ... f(x)...)) until the condition f(x)=x is met. Equality test is performed with the eq argument

Sourceval append_file : string -> string -> unit

append_file f s appends s to file f
