emit message event when client is the one sending the message

[jmcbee]

Currently the message event only gets emitted when messages are from others.

I can't find the line though that prevents that from happening.

This is because the IRC networks doesn't respond when you send messages, like incoming messages/joins/parts/etc do.

Here's the function for sending messages:

I'm not sure if sending messages should emit an event at all (let me think about it..). But if it so, it should probably be emitted by the .send() function.

The object emitted by the message event is pretty simple:

{ 
  to: 'x',
  from: 'y',
  message: 'z'
}

And the event could be triggered like this (from within the .send() function):

this.emit("message", msgObj);
