Standard Library

Below is the API for the OCaml standard library. It's directly copied over from the OCaml Manual, formatted to the Reason syntax and styled accordingly. The API docs are work-in-progress; we'll be polishing these gradually!

If you're targeting JavaScript, the API docs for BuckleScript includes all of below, plus JS-specific APIs.

Module Char

module Char: sig .. end
Character operations.

let code: char => int;
Return the ASCII code of the argument.
let chr: int => char;
Return the character with the given ASCII code. Raise Invalid_argument "Char.chr" if the argument is outside the range 0--255.
let escaped: char => string;
Return a string representing the given character, with special characters escaped following the lexical conventions of OCaml.
let lowercase: char => char;
Convert the given character to its equivalent lowercase character.
let uppercase: char => char;
Convert the given character to its equivalent uppercase character.
type t = char;
An alias for the type of characters.
let compare: t => t => int;
The comparison function for characters, with the same specification as Along with the type t, this function compare allows the module Char to be passed as argument to the functors Set.Make and Map.Make.
