query: invalid node type at position 268 and other errors

[kmaasrud]

The latest tree-sitter-nix gives me a bunch of errors and fails to parse any Nix buffer. The error I get printed as virtual text in my editor is: <nix-store-path-to-nvim>/share/nvim/runtime/lua/vim/treesitter/query.lua:161: query: invalid node type at position 268.

Running :checkhealth nvim-treesitter gives me the following:

  - ERROR: nix(highlights): ...ed-0.6.1/share/nvim/runtime/lua/vim/treesitter/query.lua:161: query: invalid node type at position 268

I have installed the Nix grammar through Nix (vimPlugins.nvim-treesitter.withPlugins (plugins: [ ... plugins.tree-sitter-nix ... ])). My system is an Macbook Air M1 running the latest macOS 12.3 and I have Neovim 0.6.1 installed.

I am not quite sure how to interpret these errors, and if the fault is with me or with the grammar. Any help is very much appreciated 😄

I also have this issue running NixOS from the nixpkgs-unstable branch. This PR should help, seems it's already merged in at least master and nixos-unstable-small.

[kmaasrud]

Thanks for the additional info @Electrostasy! I saw that PR too, and according to @siraben it seems that the issue might be with the queries, not the grammar (- as the error message does indeed indicate.) This should at least be documented, as I'm apparently not the only one whose tree-sitter config is rendered broken.

Hey all,

Sorry, I didn't realize third-parties/packagers would automatically follow master (at least not without any testing being done first). My apologies for the hassle. I wanted to add a breaking change to get the grammar up to parity with the official Nix parser (i.e. the support for interpolation syntax in paths that was added to Nix in NixOS/nix#5066), and took this as an opportunity to address the collective feedback regarding naming and the shape of the AST. I don't expect any further big changes, and I hope to soon release a version 1.0.0 that can give some assurance around that.

I believe that with nvim-treesitter/nvim-treesitter#2957 and NixOS/nixpkgs#174740 this issue can be closed.

Hi everyone,

I just installed the nix grammar for treesitter using :TSInstall nix, i.e. I do not use the grammar from Nixpkgs, and I have the exact same issues as above.

Specifically, my nix code is not highlighted and when running :checkhealth nvim-treesitter, I get:

How should I proceed to fix this issue?

In any case, thanks a lot for the hard work! I really appreciate that there is a treesitter grammar for nix!
