Neovim highlight is (sometimes) broken

[Tazoeur]

Sometimes (3 out of 4 times I'd say), instead of providing a good highliting, I have the following error instead.

Error detected while processing BufReadPost Autocommands for "*":

Here's what checkhealth nvim-treesitter provides

- ✅ OK `node` found v23.11.1 (only needed for :TSInstallFromGrammar)
- ✅ OK `git` executable found.
- ✅ OK `cc` executable found. Selected from { vim.NIL, "cc", "gcc", "clang", "cl", "zig" }
  Version: cc (Ubuntu 11.4.0-1ubuntu1~22.04.2) 11.4.0
- ✅ OK Neovim was compiled with tree-sitter runtime ABI version 15 (required >=13). Parsers must be compatible with runtime ABI.

I have relied on the TS "ensure_installed" property to install the nu parser, because I understood we shouldn't install this repository as nvim plugin anymore.

I don't really understand why sometimes it's working as intended, and sometimes I get this error...

I hope this bug report is useful, in the meantime do you think of a workaround ?

tree-sitter-nu is not compatible with https://github.com/LhKipp/nvim-nu.

You probably don't need it if you know how to setup nu-lsp

I am having the same issue I believe. @blindFS are you saying if I remove the LhKipp/nvim-nu plugin, then the tree sitter nu will install without this error? Because at the end of the day I am mainly interested in getting highlighting to work.

Yes, install the latest main (not the master branch) of nvim-treesitter, then :TSInstall nu.

@blindFS sorry I am not really familiar with tree sitter itself because I rarely have to do anything. Most languages are working out of the box. I have updated my tree sitter install to use the main branch. I have done :TSInstall nu. It seemed to have worked, because I had a feedback message and when I run :checkhealth I see it installed. However when I navigate to a file like "config.nu", it is not recognised. The text stays all white and :set ft? returns nothing. Setting this file type to "nu" or "nushell" does not seem to do the trick either.

Is there a setting I need to implement in order to make nvim+treesitter start handling these files?

[blindFS]

@mig-hub I use a nvim distro so I don't have to set it up manually.

But I guess this is what you're looking for.

@blindFS Actually I had already something similar, but I had "*.nu" as a pattern instead of just "nu". It is all working fine now. Thank you for your feedbacks !
