Hey folks!

We’ve finally reached the point where in devenv.sh we’re experimenting on what would be the interface for packaging using your favorite $LANGUAGE into Nix.

Starting with something like this:

{ pkgs, lib, config, ... }: {

  languages.rust.enable = true;
  languages.rust.import = {
    mypackage = {
      root = ./.;
    };
  };

  packages = languages.rust.import.mypackage.packages;

  outputs.mypackage = config.languages.rust.import.mypackage.packages;
}

The main idea is that when you run devenv shell, you get an environment. When you run devenv build outputs.mypackage it builds you a Nix package - that you can later deploy to a container.

I’m mostly interested if this is simple enough and it’s clear to understand what’s going on here.
