Berri is my little bot to test out jabber in ruby. It uses the blather gem which is built on top of xmpp4r. Blather makes it really easy to use jabber but has some oddities around group chat related events triggering.
Repo is heroku friendly. Rename the .env template to .env and edit the values for local testing. Don't forget to ps:scale app=1 or you will pull out all your hair wondering why its not running.
git clone https://github.com/zeroeth/berri.git
cd rubi
cp .env.template .env
