Message on join/leave?

[scalp42]

Hi @jimmycuadra

How would someone go about sending a message when a person join or leave a room ?

Thanks in advance for the help

Not possible currently, but not too difficult to add support for. lita-hipchat would need to hook into the on_join and on_leave methods of Jabber::MUC::SimpleMUCClient from the xmpp4r library: https://github.com/xmpp4r/xmpp4r/blob/4be950b6f6915de30f2550478308869495f54e45/lib/xmpp4r/muc/helper/simplemucclient.rb. When joining a room, callbacks would be registered with these methods similar to the existing register_muc_message_callback method: https://github.com/jimmycuadra/lita-hipchat/blob/e4958ecbb570db7e8d0deffb21722518f93f1d90/lib/lita/adapters/hipchat/connector.rb. The callbacks would then trigger events on Lita's robot object that handlers could use.

If you want to take a stab at implementing this, I'd be happy to accept a PR! Otherwise I'll leave the issue open as a feature request. Thanks for your interest!
