An example discord bot written in Elixir. Designed to be easy to understand and modify to suit to your needs, with lots of comments to explain what's going on.
Clone to the location of your choice. Create a runtime.exs file inside /config using the example provided. Once you've filled in the bot token and the (optional) guild_id section, open a terminal, ensure you're inside the project directory, and run with iex -S mix. While you're working on the bot, you can use the recompile/0 function call within this iex environment to recompile your code without re-running your app entirely. Deployment is an exercise left to the user, but there are several options. I currently deploy using a custom Dockerfile script.
