Elkarmo

Slack karma bot written in Elixir. Allows to add (or remove) karma points to other teammates.

Use @mention followed by ++ or -- (up to 5 +/-) to add/remove karma points to selected user.
Talk to the bot directly or use simple mention to display the current stats.
Say version to the bot to get the version number.
Use @your_bot_name: reset to reset karma stats.

Karma points are stored using DETS in karma_db file.

This project uses the Elixir-Slack library to communicate with Slack.

There is a blog-post which describes how this bot was built.
