example.rb

module MyUnicorn
  # Subclass the resource.
  class Resource < PoiseApplicationRuby::Resources::Unicorn::Resource
    # Give it a new name so we can find it.
    provides(:my_unicorn)
    # Add a new property. Could do more here.
    property(:listen)
  end

  # Subclass the provider.
  class Provider < PoiseApplicationRuby::Resources::Unicorn::Provider
    # Match the name from above.
    provides(:my_unicorn)

    # Set service resource options.
    def service_options(resource)
      super
      # Replace the command from the base class.
      resource.ruby_command("unicorn --listen #{new_resource.listen} #{configru_path}")
    end
  end
end


# Then use the new resource in your recipe.
application 'whatever' do
  my_unicorn do
    listen '127.0.0.1:8080'
