nixd

About

This is a feature-rich nix language server interoperating with C++ nix.

Some notable features provided by linking with the Nix library include:

• Nixpkgs option support, for all option system (NixOS/home-manager/flake-parts).
• Nixpkgs package complete, lazily evaluated.
• Shared eval caches (flake, file) with your system's Nix.
• Support for cross-file analysis (goto definition to locations in nixpkgs).

Get Started

You can try nixd without installation. We have tested some working & reproducible editor environments.
