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"
