## Description

A Ruby interface to [masscan], an Internet-scale port scanner.
Allows automating masscan and parsing masscan Binary, List, and JSON output
file formats.

## Features

* Provides a [Ruby interface][Masscan::Command] for running the `masscan`
  utility.
* Supports [parsing][Masscan::OutputFile] masscan Binary, List, and JSON output
  files.

[Masscan::Command]: https://rubydoc.info/gems/ruby-masscan/Masscan/Command
[Masscan::OutputFile]: https://rubydoc.info/gems/ruby-masscan/Masscan/OutputFile

## Examples

Run `sudo masscan` from Ruby:

```ruby
require 'masscan/command'

Masscan::Command.sudo do |masscan|
  masscan.output_format = :list
  masscan.output_file   = 'masscan.txt'

  masscan.ips   = '192.168.1.1/24'
  masscan.ports = [20,21,22,23,25,80,110,443,512,522,8080,1080]
end
```

Parse a `masscan` output file and guess the format:

```ruby
require 'masscan/output_file'

output_file = Masscan::OutputFile.new('masscan.txt')
output.format
# => :list
```

Parse `masscan` Binary output files:

```ruby
output_file = Masscan::OutputFile.new('masscan.scan', format: :binary)
output_file.each do |record|
  p record
end
```

```
