Module Stdlib.CharSource

Character operations.

Characters are the elements of string and bytes values. Characters represent bytes, that is an integer in the range [0x00;0xFF].

Some of the functions of this module interpret the characters in the range [0x00;0x7F] as the characters of the ASCII character set.

Characters

Sourcetype t = char

An alias for the type of characters.

Sourceval code : char -> int

Return the integer code of the argument.

Sourceval chr : int -> char

Return the character with the given integer code.

Sourceval escaped : char -> string

Return a string representing the given character, with special characters escaped following the lexical conventions of OCaml. All characters outside the ASCII printable range [0x20;0x7E] are escaped, as well as backslash, double-quote, and single-quote.

Predicates and comparisons

See also the Ascii module.

Sourceval compare : t -> t -> int

The comparison function for characters, with the same specification as Stdlib.compare. 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.

Sourceval equal : t -> t -> bool

The equal function for chars.

  • since 4.03

ASCII characters

Sourcemodule Ascii : sig ... end

ASCII character set support.

Sourceval lowercase_ascii : char -> char

Use the equivalent Ascii.lowercase instead.

  • since 4.03
Sourceval uppercase_ascii : char -> char

Use the equivalent Ascii.uppercase instead.

  • since 4.03

Hashing

Sourceval seeded_hash : int -> t -> int

A seeded hash function for characters, with the same output value as Hashtbl.seeded_hash. This function allows this module to be passed as argument to the functor Hashtbl.MakeSeeded.

  • since 5.1
Sourceval hash : t -> int

An unseeded hash function for characters, with the same output value as Hashtbl.hash. This function allows this module to be passed as argument to the functor Hashtbl.Make.

  • since 5.1
