Evaluation

Evaluation is the first step when it comes to building your project. It is performed by your agent as follows:

  1. At the top-level of your repository, the agent will search for a Nix file to evaluate in the following order: nix/ci.nix, ci.nix or default.nix

  2. NIX_PATH will be empty. Make sure you pin nixpkgs and not rely on <nixpkgs> search path. This is to ensure reproducability and purity also when it comes to nixpkgs

  3. If any of the attributes fail to evaluate, job evaluation phase will be marked as failed and error messages will be shown inline per attribute
