domain_name

Synopsis

Domain Name manipulation library for Ruby

Description

• Parses a domain name ready for extracting the registered domain and TLD.

    require "domain_name"
  
    host = DomainName("a.b.example.co.uk")
    host.domain         #=> "example.co.uk"
    host.tld            #=> "uk"
    host.cookie_domain?("example.co.uk")    #=> true
    host.cookie_domain?("co.uk")            #=> false
  
    host = DomainName("[::1]")  # IP addresses like "192.168.1.1" and "::1" are also acceptable
    host.ipaddr?        #=> true
    host.cookie_domain?("0:0:0:0:0:0:0:1")  #=> true
  

• Implements rudimental IDNA support.

To-do's

• Implement IDNA 2008 (and/or 2003) including the domain label validation and mapping defined in RFC 5891-5895 and UTS #46. (work in progress)

• Define a compact YAML serialization format.

Installation

gem install domain_name

Release

Releases use v-prefixed version tags. Push the release commit to master, wait for CI to pass, and then push the matching tag. A successful tag CI run publishes the gem through RubyGems trusted publishing and creates the GitHub release.

Before the first automated release, register knu/ruby-domain_name, workflow publish-gem.yml, and environment rubygems.org as a trusted publisher at https://rubygems.org/gems/domain_name/trusted_publishers/new.
