vimPlugins.nvim-treesitter: incomplete queries for javascript/typescript

[yelite]

Nixpkgs version

• Unstable (26.05)

Describe the bug

With the recent nvim-treesitter master->main update #470883 , we now have a nvim-treesitter-grammars package for parsers and queries for installed grammars. Based on

nixpkgs/pkgs/applications/editors/vim/plugins/nvim-treesitter/overrides.nix

Lines 91 to 92 in 45a1530

	queryPlugins = lib.pipe selectedGrammars [
	(map (g: g.passthru.associatedQuery or null))

for each installed grammar, it will symlink at most one query into the nvim-treesitter-grammars package. There are special cases, like js/ts queries, which inherit the ecma query (https://github.com/nvim-treesitter/nvim-treesitter/blob/2ba5ec184609a96b513bf4c53a20512d64e27f39/runtime/queries/javascript/highlights.scm#L1). The ecma query is just a base query with no corresponding grammar.

This means the following package will miss the ecma query in nvim's runtime paths. The syntax highlighting will just fail silently.

pkgs.vimPlugins.nvim-treesitter.withPlugins (p: [p.javascript])

For now, I am manually adding the ${nvim-treesitter}/runtime to rtp

      {
        plugin = my-treesitter;
        config = ''vim.opt.rtp:prepend("${my-treesitter}/runtime/")'';
        type = "lua";
      }

in my home manager neovim config to workaround this problem.

Steps to reproduce

use pkgs.vimPlugins.nvim-treesitter.withPlugins (p: [p.javascript]), open a javascript file, turn on treesitter highlight. There will be no syntax highlighting and no error message.

Expected behaviour

the ecma query should be included when javascript/typescript grammar is installed
