sab is a Hubot robot that is set up with various fun and useful plugins.
All configuration data is stored in config.sh. config.sh.dist is available to get you jumpstarted.
Some plugins that are installed require third party API keys. Store those keys in your config.sh file, but update config.sh.dist with an empty variable.
Then also update dev_runner.sh and Makefile with the usage of those keys, so the local instance of sab can pick it up; as well as make init-heroku seeing it when pushing your config changes up to Heroku.
Don't store your API keys directly in your plugin.
For developing on sab, we have a handy shell script to boot up an instance with the necessary environment data.
./dev_runner.sh
If it says you need to remove scripts/mongolab-brain.coffee, do that so your testing doesn't affect the production MongoDB database.
After attaching your Heroku app to your local directory, via heroku git:remote -a {APP NAME}, run make init-heroku to automatically run the Heroku config commands to create the environment variables for sab to run properly.
