treesitter not working

[danyspin97]

Hello! I have been using rocks since last weekend, it works awesome but unfortunately I cannot get treesitter to work correctly.

I have added rocks-treesitter.nvim but I get loads of messages about the tresitter lua file failing to load:

[1/1] treesitter for rust has been installed
Could not load parser for rust: nvim-linux-x86_64/share/lua/vim/treesitter/launguage.lua:104

It was working with lazy.nvim before, I ported the configuration (what I could at least) but I have some trouble to make it work.

Also, with the parser in lua i am experiencing this issue: nvim-treesitter/nvim-treesitter#2260.

My rocks.toml contain the following:

"rocks-treesitter.nvim" = "scm"
nvim-treesitter = "0.9.2"

Hey 👋

This plugin has nothing to do directly with nvim-treesitter.
It's also still very early in the development.

See this readme section for how to configure it.

If you add rust to the treesitter.auto_highlight list (or set it to the string "all"), it should prompt you to install tree-sitter-rust from luarocks when you open a rust file (you can also install it manually with :Rocks install tree-sitter-rust).

Also, with the parser in lua i am experiencing this issue: nvim-treesitter/nvim-treesitter#2260.

nvim-treesitter's :TSInstall doesn't work with rocks.nvim (it does if you install it with rocks-git.nvim).
We recommend to install parsers from luarocks instead - either using :Rocks install tree-sitter-<lang> (where <lang> is the parser language), or by configuring rocks-treesitter.nvim to install it automatically when needed.

nvim-treesitter = "0.9.2"

nvim-treesitter 0.9.2 targets Neovim 0.9, and many of its queries are outdated, compared to the parsers we install from luarocks (which come bundled with matching queries).
If you install parsers from luarocks, you shouldn't need nvim-treesitter, unless you want its extra features like tree-sitter based folds and indentation.

If you do need it, you can install the dev version (which targets the main branch):

:Rocks install nvim-treesitter dev

Or, with rocks-git.nvim, you can install it from the git repo

:Rocks install nvim-treesitter/nvim-treesitter branch=main

Thanks for the detailed explanation :) I couldn't understand the relationship between nvim-treesitter and rocks-treesitter.nvim and that with all the errors happening I couldn't figure out the issue.

I had the auto download feature of nvim-treesitter enabled, and even though the plugin wasn't added in rocks.toml, it was still working and creating some issues.

I don't have any preference towards nvim-treesitter, so rocks-treesitter.nvim is good enough for me. I understand that this plugin is still in development, and I'd like to thank you for the great work you have been putting.

I'll keep following the development, as unfortunately the treesitter parsers installed by rocks.nvim still don't load.

unfortunately the treesitter parsers installed by rocks.nvim still don't load.

What do you mean by "don't load"? Are they not working with another plugin?

For highlighting, you either need to add the languages to auto_highlight list, or you can call vim.treesitter.start() (e.g. in an ftplugin/<filetype>.lua).

If that's not working, there might be a bug.

With auto_highlight set to all, treesitter failed to load the plugin for rust and toml (giving an error message similar to the one posted before). Today, I have updated all plugins once again and now it's loading! 😄

Error in this line in toml config: [treesitter]

auto_highlight = "all"

NOTE: These are parsers, not filetypes.

auto_highlight = [
"haskell",
"dhall",
"rust",
"toml"
]
auto_install = "prompt" # true | false

What do you mean? Could you please provide some details?

When I use the settings that appear in the readme I have an error and when I remove them everything works perfectly

See #8. I've corrected the snippet in the readme.
