Simple and Fast hexdumping for Ruby.
- Can hexdump any Object supporting the
each_bytemethod. - Can send the hexdump output to any Object supporting the
<<method. - Can yield each line of hexdump, instead of printing the output.
- Supports printing ASCII, hexadecimal, decimal, octal and binary bytes.
- Supports hexdumping bytes (8bit), words (16bit), double-words (32bit), and quad-words (64bit).
- Supports Little Endian and Big Endian modes.
- Makes {String}, {StringIO}, {IO}, {File} objects hexdumpable.
- Fast-ish.
