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