Setup

IDE

If you're using an IDE with CMake integration make sure it points to the same cmake directory as the justfile, which defaults to build.

This will reduce friction when working on the project.

Nix

• Use nix flake update to bring all nix context and packages
• Use nix build to build the package
• Use nix run to launch the module-viewer and check your module loads properly
• Use nix develop to setup your IDE

Troubleshooting

Nix + IDE Integration

If your IDE reports that a file doesn't belong to the project or that files cannot be found, the CMake cache is likely missing the Nix-provided paths. This happens when the IDE runs CMake on its own, outside the Nix environment, leaving the required paths empty.

To fix it:

1. Regenerate the cache from within the Nix shell

   This provides the required Nix paths and writes them into build/CMakeCache.txt:

   nix develop -c just configure

2. Reload the CMake project without resetting the cache

   If on RustRover: Open the CMake tool window (View → Tool Windows → CMake) and click the Reload button (↺) in the toolbar.

Resetting the cache would wipe the paths you just wrote, so make sure to reload only.
