[erlang-questions] NineNines Bullet
Tue Apr 2 23:00:09 CEST 2013
Yes, that's how I was seeing it. Mentally at least. I've got a similar thing built in Go which I want to port to Erlang using Bullet. Go's websocket implementation is quite far from complete and has been a headache to work with. I'm hoping to have something a lot more robust with Erlang.
So, let me get this straight… init handles the connection setup and terminate handles the teardown. So, I can make calls in those two functions to add the user to a room collection or removing her.
What are the differences between stream and info? When do those come into play? I'm assuming one (stream?) is invoked when data is sent from the end user. Is that right?

> The basic idea is that when your process connects its pid is added to a list somewhere (gproc, gen_server, anything else). When a message is sent to the room, all pids in the list receive it. You can also broadcast when someone enters or leave the room. And you remove the pid from the list when it's gone (using monitors for example).
