This enables autocomplete, type errors, hover, and go-to-definition directly in .nix files with no transpilation. It successfully parses and type-checks all 42,298 nixpkgs files in 13 seconds. Bundled types cover Lib, Stdenv, Platform, Derivation, and pkgs/by-name packages. VSCode and Neovim LSP integrations are available. Currently a proof of concept with known limitations around implicit any and circular references. ## Full article daily.dev links to this article rather than hosting it.
