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"
Support for Mac OS is not guaranteed (see PR #61).
nix-env -i -f https://github.com/nix-community/rnix-lsp/archive/master.tar.gz
These instructions are not fully tested - see issue #3. Please raise an issue and/or send a PR if a config below didn't work out of the box.

kak-lsp has builtin configuration since version v9.0.0:
[language.nix]
filetypes = ["nix"]
roots = ["flake.nix", "shell.nix", ".git"]
command = "rnix-lsp"
If you run into an issue regarding "missing roots" see this issue.
