Some time ago we started developing using Elixir language and we loved it! As usual, we wanted to focus on code logic rather than on code style, so we also started using Credo a great tool to examine elixir code developed by René Föhring (@rrrene) So far so good, but we all make mistakes, and sometimes developers send a pull request without fixing all credo warnings/errors. A few times of this happening was enough proof to consider that we needed a tool to automatically check the code whenever a pull request was created.

We know this type of tools already exist for other languages (Gadget, Hounci), but unfortunately, we did not find one for credo/elixir. As always, if we don’t find something we need, we build it!

So that’s how CredoCI was born. Want to know more about it? Check this out
