Eventmachine talk - Jun 2007 - Popen implemented, give it a try

Thanks to Bill Kelly for a lot of suggestions and a lot of research.

You can now do this:

module MyHandler
  def receive_data data
    puts data
  end
  def unbind
    puts "Unbound"
  end
end

EM.run {
  EM.popen "ls -ltr", MyHandler
}

EventMachine#popen runs the given command in a subprocesses connected to the
main reactor loop with a full-duplex socketpair. Use
EventMachine::Connection#get_pid to get the kernel PID of the subprocess in
case you need it. The handler module or class works just like any other. You
can imagine that you''re connected to a TCP server. Nothing is
different.

Good luck and if you try it, please leave feedback here.

Thanks, Francis !!

This will be ideal for my current project.
