rnix-lsp 0.1.0

A work-in-progress language server for Nix, with syntax checking and basic completion
rnix-lsp-0.1.0 is not a library.

rnix-lsp Crates.io

A syntax-checking language server using rnix.

  • Syntax-checking diagnostics
  • Basic completion
  • Basic renaming
  • Basic goto definition
  • Expand selection proposal
  • Formatting using nixpkgs-fmt

This is beta-level quality at best - I didn't expect maintaining a language server when writing rnix, the goal was that others would flock around the parser and write a bunch of editor tooling :)

Breakages are expected. No semver compatibility before 1.x.y.

Turn on logging with RUST_LOG=trace, and redirect stderr to a file.

bash -c "env RUST_LOG=trace rnix-lsp 2> /tmp/rnix-lsp.log"

Integrate with your editor
