hateoas.rb

This is the source code for HATEOAS, a gem to help you build client libraries for hypertext APIs. This code is NOT ready for any kind of production, and is frankly terrible. It’s like two hours of work. Please don’t hate me.

 
require 'hateoas/version'
require 'open-uri'
require 'mechanize'

module Hateoas
  class << self
    attr_accessor :rel_namespace
    attr_writer :base_uri, :current_state

    def base_uri
      if ENV['HATEOAS_ENV'] == "development"
        development_base_uri || "#{@base_uri}.dev"
      else
        @base_uri
      end
    end

    def current_page
      current_state.body
    end

    def current_state
      @current_state ||= user_agent.get(base_uri)
    end

    def user_agent
      @user_agent ||= Mechanize.new
    end

  end

  module DSL
    extend self

    def click_link(rel)
      if Hateoas.rel_namespace
        rel = "/#{Hateoas.rel_namespace}/#{rel}"
      end

      Hateoas.current_state = Hateoas.user_agent.click(Hateoas.current_state.links.find{|l| l.attributes["rel"] == rel })
    end
  end
end
