To evaluate Nix expressions, you use `nix eval` or `nix-instantiate` to query attribute values and inspect derivation inputs, outputs, and environment variables directly from your Nix code.
Debugging Nix evaluation errors involves running `nix eval` or `nix-instantiate` with the `--show-trace` flag to pinpoint the exact location and cause of the failure within your Nix expressions.
Yes, you can inspect flake-based Nix projects by evaluating flake outputs to examine derivations, check build inputs, and identify evaluation issues causing your package build failures.
Nix package build failures during evaluation often stem from incorrect derivation inputs or syntax errors. You can evaluate the relevant Nix expression and use `--show-trace` to identify the specific issue.
Yes, `nix eval` works with nixpkgs to query Nix language semantics, allowing you to evaluate expressions, inspect derivation attributes, and understand how traditional and flake-based projects are structured.
