Summary

A cruel mistress that uses the public suffix domain list to dominate URLs by canonicalizing, finding public suffixes, and breaking them into their domain parts.

Description

This simple library can parse a URL into its canonical form. It uses the list of domains from http://publicsuffix.org to break the domain into its public suffix, domain, and subdomain.

Installation

  gem install domainatrix --source http://gemcutter.org

Use

require 'rubygems'
require 'domainatrix'

url = Domainatrix.parse("http://www.pauldix.net")
url.url       # => "http://www.pauldix.net" (the original url)
url.public_suffix       # => "net"
url.domain    # => "pauldix"
url.canonical # => "net.pauldix"

url = Domainatrix.parse("http://foo.bar.pauldix.co.uk/asdf.html?q=arg")
url.public_suffix       # => "co.uk"
url.domain    # => "pauldix"
url.subdomain # => "foo.bar"
url.path      # => "/asdf.html?q=arg"
url.canonical # => "uk.co.pauldix.bar.foo/asdf.html?q=arg"
