Description

Fully Featured and Fast hexdumping for Ruby.

Features

Supports printing ASCII, hexadecimal, decimal, octal and binary bytes.
Supports hexdumping bytes, characters, signed/unsigned integers, floating-point numbers, and in little/big/network endian byte orders:
- char - signed 8bit ASCII character
- uchar - unsigned 8bit ASCII character
- int8 - signed 8bit integer
- uin8 / byte - unsigned 8bit integer (default)
- int16 / short - signed 16bit integer

Supports displaying UTF-8 characters or other character encodings.
Supports ANSI styling and highlighting.
Can hexdump any Object supporting the each_byte method.
Can send the hexdump output to any Object supporting the << method.
Makes {String}, {StringIO}, {IO}, {File} objects hexdumpable.
Fast-ish.
