A sinatra application that listens for an incoming webhook from you public slack channels & posts gifs back to them.

Create an ingoing and outgoing webhook in your slack account. You will also need to know the name of your slack sub domain & where you have placed your gifs.

The directory structure should be

´´´ ASSET_BASE_URL/TAG_NAME/NUMBER.gif ´´´

This will create a url that looks like

http://box.tv4.se/slackr-gif-bot/hey-everybody-look-at-me/0.gif

To start it from the command line run it like this:

´´´ SLACK_IN_TOKEN=YOUR_INCOMING_WEBHOOK_TOKEN SLACK_OUT_TOKEN=YOUR_OUTGOING_WEBHOOK_TOKEN SLACK_HOST=YOUR_SLACK_HOST ASSET_BASE_URL=YOUR_ASSET_BASE_URL rackup ´´´
