slack -> jabber -> irc -> erc

Slack can be used though alternative gateways appart from the slack clients themselves.  They offer both jabber and irc gateways that map quite well to slack model.

I had previously used the irc gateway, and erc did the trick with no extra configuration at all. But things changed and now I only have the jabber gateway at my disposal.

The problem is that if you want to use a decent emacs client, you'll have to use bitlbee and end up mapping jabber to irc, so you can use erc/circe/rcirc (which are far better at IRC protocol than jabber.el is at xmpp)



To chat privately other peers it's a matter of /j name-of-the-buddy.  Joining rooms is not as direct, and first you have to create some 'mapping' rooms in your bitblee configuration, before being able to join them.

Whatever, here's how to integrate slack with bitlbee (and with erc)

On bitlbee buffer:

•  chat add 0 room-name@conference.myserver-foo.xmpp.slack.com

 0 stands for the account number. 'conference' has  to be there. it's a plain string, you don't have to substitute it for anything. replace myserver-foo for your server name. room-name is the name of the chat in slack

• chat list

This will show you the rooms available

• /join room-name

Notice no # sign.

• channel 4 del

4 is the chat you want to remove in case you messed up with something.

And that's it. Now you can slack from erc, and you can use all erc machinery (yes erc-robot, I'm looking at you).
