Hexen

Yet another library for encoding and decoding hexadecimal byte sequences.

Quick start

You can install hexen using the OPAM package manager or another method. If you are using Dune, add hexen to your dependencies.

In use

Hexen provides high-level functions like encode and decode for quick encoding and decoding of strings or substrings.

Hexen.encode "Hello World";;
(* - : string = "48656c6c6f20576f726c64" *)

Hexen.decode "48656c6c6f20576f726c64";;
(* - : string = "Hello World" *)

Hexen.encode_substring "Hello World" 0 5;;
(* - : string = "48656c6c6f" *)

Hexen.decode_substring "48656c6c6f20576f726c64" 0 10;;
(* - : string = "Hello" *)

Also, Hexen provides functions to encode and decode strings or substrings directly into existing buffers or bytes.

let buffer = Buffer.create 16 in

Hexen.encode_to_buffer buffer "Hello";
Hexen.encode_substring_to_buffer buffer "Hello World" 5 6;

let bytes = Bytes.create 12 in 
Hexen.decode_into (Buffer.contents buffer) 0 bytes 0 22;
Bytes.set bytes 11 '!';

bytes
(* - : bytes = Bytes.of_string "Hello World!" *)
