How to delete default nvim parser? Getting 'query: invalid node type' error

[Ashe]

Hello, for the longest time I've been dealing with tedious issues with treesitter. It sometimes goes away, sometimes doesn't, but I've had enough. I saw on the FAQ that this is a common error caused by multiple parsers. I ran :echo nvim_get_runtime_file('parser', v:true) and got this:

['/nix/store/avmr95wgfjyzi6n1axbjx9x9952s1d01-neovim-unwrapped-0.9.1/lib/nvim/parser', '/home/ashe/.local/share/nvim-treesitter/parsers/parser']  

I can't figure out for the life of me how to disable the standard nvim parser, or any sort of acknowledgement online that this is a feature and how to get rid of it. I hope someone knows?

Thank you!

You can't (or rather, shouldn't). You need to make sure that the parser directory has the same precedence over the bundled directory that the query directory has over the one in $VIMRUNTIME.

How to do that with Nix, I cannot tell you, sorry.

Thank you for your reply, I'm trying to use the package pkgs.vimPlugins.nvim-treesitter.withAllGrammers. The command that you suggest to run now fills my screen with parsers, but at the same time I'm not seeing the errors anymore, so maybe this is how we should be setting this up on nix.

Thank you for letting me know this wasn't really a config issue and more of a nix thing :)

one way is to manipulate the vim.opt.rtp (runtimepath)

for example, I originally have multiple paths for parser like you

:echo nvim_get_runtime_file('parser', v:true)
['/Users/rubelagu/.local/share/nvim/lazy/nvim-treesitter/parser', '/usr/local/Cellar/neovim/0.9.5/lib/nvim/parser']

I can remove the /usr/local/Cellar/neovim/0.9.5/lib/nvim from runtimepath(:h 'runtimepath) using vim.opt.rtp. Beware if you are using lazy.nvim as plugin manager since it will reset the runtimepath unless you set the performance.rtp.reset=false

vim.opt.rtp:remove("/usr/local/Cellar/neovim/0.9.5/lib/nvim") -- this is the important bit 
require("lazy").setup("ecerulm.plugins", {
  -- https://github.com/folke/lazy.nvim
  performance = {
    rtp = {
      reset = false -- I need this because otherwise lazy.nvim reset the runtimepath
    },
  },
	change_detection = {
		enabled = true, -- automatically check for config file changes and reload the ui
		notify = false, -- turn off notifications whenever plugin changes are made
	},
})

Alternatively you can put the

vim.opt.rtp:remove("/usr/local/Cellar/neovim/0.9.5/lib/nvim") 

after the lazy.nvim and that should work too.

No, that is very dangerous advice. Never mess with the bundled runtime! Instead you should make sure that nvim-treesitter takes precedence on your runtimepath; this should normally be the case, and if Lazy messes this up, it should be fixed. (DO NOT lazy-load nvim-treesitter; that is not supported!)

The only thing that goes in /usr/local/Cellar/neovim/0.9.5/lib/nvim is the parser

find /usr/local/Cellar/neovim/0.9.5/lib/nvim
/usr/local/Cellar/neovim/0.9.5/lib/nvim
/usr/local/Cellar/neovim/0.9.5/lib/nvim/parser
/usr/local/Cellar/neovim/0.9.5/lib/nvim/parser/c.so
/usr/local/Cellar/neovim/0.9.5/lib/nvim/parser/vim.so
/usr/local/Cellar/neovim/0.9.5/lib/nvim/parser/vimdoc.so
/usr/local/Cellar/neovim/0.9.5/lib/nvim/parser/lua.so
/usr/local/Cellar/neovim/0.9.5/lib/nvim/parser/query.so

But you are right in that by disabling the lazy loading

{
	"nvim-treesitter/nvim-treesitter",
         lazy = false,

it works without having to remove the that directory from the runtimepath.

Yes, and they are there for a reason. Removing them (without installing a compatible(!) version externally) will break Neovim.
