vimPlugins.nvim-treesitter.withAllGrammars: "module nvim-treesitter.configs not found"

[NobbZ]

Nixpkgs version

• Unstable (26.05)

Describe the bug

When I build my neovim with a recent nixpkgs, I get a lua stacktrace in neovim when opining any file that has associated grammars (see logs).

I was able to bisect this down to d5146f4 (#470883)

Steps to reproduce

nix run --override-input nixpkgs github:nixos/nixpkgs/4978a37c9ff1809794c12f915afcb6d6313ed4e5 github:nobbz/nobbz-vim -- foo.md

You will see a pop up notification first, and then a permanent split pane with the full error at the bottom.

Expected behaviour

neovim works with treesitter

I now realized the PR has something in the release notes, suggesting to either "migrate" without any note about where to find instructions about that, or alternatively use the nvim-treesitter-legacy attribute which is missing…

So nvim-treesitter is broken and the docs about it are as well…

[christoph-blessing]

I had the same error but I fixed it by removing the following line from my Lazy configuration for nvim-treesitter:

main = "nvim-treesitter.configs"

[NobbZ]

Oh, indeed I do see my problem now.

Still I consider the mention of nvim-treesitter-legacy as a "fallback" in the changelog as an issue that needs to get addressed.

[adamcstephens]

The legacy fallback is in this non-merged PR #472119

[HeitorAugustoLN]

You can find the following in the nvim-treesitter README for migrating:

-- Highlighting
vim.api.nvim_create_autocmd('FileType', {
  pattern = { '<filetypes>' },
  callback = function() vim.treesitter.start() end,
})

-- Indent
vim.bo.indentexpr = "v:lua.require'nvim-treesitter'.indentexpr()"

-- Folding
vim.wo[0][0].foldexpr = 'v:lua.vim.treesitter.foldexpr()'
vim.wo[0][0].foldmethod = 'expr'

Some discussion in upstream that might be of your interest:

nvim-treesitter/nvim-treesitter#7901
nvim-treesitter/nvim-treesitter#7927

Note

Incremental selection is not available after the update.

Note

You do not have to call setup for nvim-treesitter after the update

@PerchunPak @khaneliman @mrcjkb that are working on it

[PerchunPak]

Please just merge that PR. This is far from the first time such confusion has happened and will happen

@NixOS/neovim

[PerchunPak]

#472119 has been finally merged, so I think this is resolved
