Detecting when a user leaves or enters a channel with hubot

coffeescript, hubot, irc

Solution

Hubot's `Robot` class has functions `enter` and `leave` that will fire a callback you give when any user enters or leaves the room. That callback takes a `Response`, which has a property `message` of type `Message`, which in turn has a property `user` of type `User`.

module.exports = (robot) ->
   robot.enter (response) ->
     # at this point you can get the user's name with:
     # response.message.user.name
     # works the same for robot.leave

However, it appears that the IRC adapter for hubot doesn't currently fire the messages needed to get those functions to work.

Problem

I am trying to make Hubot detect when a user enters or leaves a channel, but so far I have been unable to actually find ANY information pertaining to this. Does anyone have any ideas of how to do this? :) Thanks in advance!
