So I wanted to create some default options in my parser. I'm not sure if this is how you would do it, but this is what I figured out...

mailing_list.rb

module Burst
  class MailingList
    include Typhoeus
    DEFAULT_KEY  = 'SECRET'
    DEFAULT_HOST = '127.0.0.1'
    DEFAULT_PORT = 3000

    remote_defaults :on_success  => lambda {|response| Yajl::Parser.parse(response.body)},
                    :on_failure  => lambda {|response| raise "Error code: #{response.code}"},
                    :base_uri    => "http://"
                    
    define_remote_method :pull_remote,
                         :params => {:expanded => true, :auth_token => DEFAULT_KEY},
                         :path   => ":host::port/mailing_lists/:id.json"
   
    def self.pull(args)
      args[:host] ||= DEFAULT_HOST
      args[:port] ||= DEFAULT_PORT
      raise "Cannot execute with providing an ID" unless args[:id]
      self.pull_remote(args)
    end
  end
end
