Hey Everyone,
I just read through the release announcement for mixnix and figured it would be a good time to also announce the project I have been working through. rebar32nix (read: Rebar3 to nix).
It will read your projects rebar3.lock file and generate a nix file for you to be able to build your applications from. It currently supports both hex and git dependencies, and I plan to support more down the road.
If you have rebar3 project, I would be greatful if you gave it a go and let me know your thoughts or any issues you may come across.
