EventMachine echo server

Edit: I am trying to find the public interface for event servers and connections.

We need the require 'rubygems' so that the interpreter will know to search the rubygems install paths. Apparently, module locations are not hard coded into the interpreter.

#!/usr/bin/env ruby                                                              
require 'rubygems'
require 'eventmachine'

port = ARGV[0].to_i
puts "PORT>>>#{port}<<<"

module Echo
  def receive_data(data)
    puts "RECV>>>#{data.chomp}<<<"
    send_data(data)
    puts "SEND>>>#{data.chomp}<<<"
    if data.downcase.chomp == 'quit'
      EM.next_tick { EM.stop }
    end
  end
end

EM.run do
  EM.start_server("0.0.0.0", port, Echo)
end
