## 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
  * `int16_le` / `short_le` - signed 16bit integer (little endian)
  * `int16_be` / `short_be` - signed 16bit integer (big endian)
  * `int16_ne` / `short_ne` - signed 16bit integer (network endian)
  * `uint16` / `ushort` - unsigned 16bit integer
  * `uint16_le` / `ushort_le` - unsigned 16bit integer (little endian)
  * `uint16_be` / `ushort_be` - unsigned 16bit integer (big endian)
  * `uint16_ne` / `ushort_ne` - unsigned 16bit integer (network endian)
  * `int32` / `int` - signed 32bit integer
  * `int32_le` / `int_le` - signed 32bit integer (little endian)
  * `int32_be` / `int_be` - signed 32bit integer (big endian)
  * `int32_ne` / `int_ne` - signed 32bit integer (network endian)
  * `uint32` / `uint` / - unsigned 32bit integer
  * `uint32_le` / `uint_le` - unsigned 32bit integer
    (little endian)
  * `uint32_be` / `uint_be` - unsigned 32bit integer (big endian)
  * `uint32_ne` / `uint_ne` - unsigned 32bit integer
    (network endian)
  * `int64` / `long` / `long_long` - signed 64bit integer
  * `int64_le` / `long_le` / `long_long_le` - signed 64bit integer
    (little endian)
  * `int64_be` / `long_be` / `long_long_be` - signed 64bit integer (big endian)
  * `int64_ne` / `long_ne` / `long_long_ne` - signed 64bit integer
    (network endian)
  * `uint64` `ulong` / `ulong_long` - unsigned 64bit integer

  * `double_le` - double precision 64bit floating-point number (little endian)
  * `double_be` - double precision 64bit floating-point number (big endian)
  * `double_ne` - double precision 64bit floating-point number (network endian)
* Supports optionally skipping N bytes or reading at most N bytes of data.
* Supports optional zero-padding of the data.
* Supports omitting repeating rows with a `*`.
* Supports grouping columns together like GNU `hexdump -C`.
* Supports grouping characters together to align with the type's size.
* Supports displaying characters inline like GNU `hexdump -c`.
* 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.

### ANSI Styling

```ruby
Hexdump.hexdump("ABCD", style: {index: :white, numeric: :green, chars: :cyan})
```

### ANSI Highlighting

```ruby
Hexdump.hexdump((0..255).map(&:chr).join, highlights: {
  index: {/00$/ => [:white, :bold]},
  numeric: {
    /^[8-f][0-9a-f]$/ => :faint,
    /f/  => :cyan,
    '00' => [:black, :on_red]
  },
  chars: {/[^\.]+/ => :green}
})
```

### Block Configuration

```ruby
Hexdump.hexdump("hello\0") do |hex|
  hex.type = :uint16_le
  hex.group_chars = :type
  # ...
end
# 00000000  6568 6c6c 006f                           |he|ll|o.|
# 00000006
```

## Benchmarks

Benchmarks show hexdumping 1Mb of random data.
