em-ucengine is a Ruby library for U.C.Engine powered by EventMachine. It can connect, subscribe and publish events to U.C.Engine.

Install

Install with Rubygems:

gem install em-ucengine

If you use bundler, add it to your Gemfile:

Usage

Client

EventMachine

We have a classic block style API:

require "em-ucengine"
EventMachine::UCEngine::Client.run do |uce|
  uce.connect("participant", "pwd") do |err, session|
    EM.add_periodic_timer(1) { session.publish("em-ucengine.example.ping", "demo") }
    session.subscribe("demo") do |err, event|
      puts "Hey, we received an event: #{event.inspect}"
    end
  end
end

Each method call return a deferable.

require "em-ucengine"
EventMachine::UCEngine::Client.run do |uce|
  req = uce.connect("participant", "pwd")
  req.callback do |session|
    session.publish("em-ucengine.example.ping", "demo")
  end
  req.errback do |error|
     puts "error"
  end
end

Net/HTTP

require "em-ucengine"

uce = UCEngine::Client.new
session = uce.connect("participant", "pwd")
session.publish("em-ucengine.example.ping", "demo")

Brick

require "em-ucengine"
require "em-ucengine/brick"

class MyBrick
  include EM::UCEngine::Brick

  on "ping" do |event|
    puts event
  end
end

brick = MyBrick.run

Don't hesitate to look at the specs for more examples ;-)

TODO

• Release the gem with another name
• Complete the specs
• Implements the download and upload methods for the Net::HTTP backend
