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

Install Default domainatrix

  gem install shadowbq-domainatrix

Using Github Custom version in a GemFile

Installing a gem directly from a git repository is a feature of Bundler, not a feature of RubyGems. Gems installed this way will not show up when you run gem list.

  gem 'domainatrix', :git => 'git://github.com/shadowbq/domainatrix.git'

Use

require 'rubygems'
require 'domainatrix'

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

# Looking at scheme and paths
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"
url.scheme    #=> "http"

# ICANN section only suffix search using DynDNS'
url = Domainatrix.icann_parse('www.foo.dyndns.org') 
url.host #=> 'www.foo.dyndns.org' }
url.url #=> 'http://www.foo.dyndns.org/' }
url.public_suffix #=>'org' }
url.domain #=>'dyndns' }
url.subdomain #=> 'www.foo' }
url.domain_with_tld  #=> 'dyndns.org' }

# Scanning text line
urls = Domainatrix.scan("wikipedia (http://en.wikipedia.org/wiki/Popular_culture): lol") do |match|
         match.url # Given a block, works like 'map'
       end
urls # => ["http://en.wikipedia.org/wiki/Popular_culture"]
