Question

I wrote a simple EventMachine server like this one:

EventMachine.run do
  EventMachine::WebSocket.start(:host => HOST, :port => PORT) do |ws|
    # snip...
  end
end

Now, I would like to trigger it from another file in another directory. If EventMachine would be a simple Ruby class I would add a run (or something) class method and do something like:

#!/usr/bin/env ruby
$LOAD_PATH << "./lib"
require "my_event_machine"
MyEventMachine.run

Any idea how to do this? Thanks!

You already had the solution:

my_app.rb:

class MyApp
  def run
    EM.run do
      EM::WebSocket.start(:host => HOST, :port => PORT) do |ws|
        # snip...
      end
    end
  end
end

run.rb:

#!/usr/bin/env ruby
$LOAD_PATH << "./lib"
require "my_app"
MyApp.new.run
