Treesitter main branch support

[ojsef39]

I have confirmed that this is a bug related to nvf

• This is a bug, and not an user error or a support request. I understand that my issue will be closed if it is not a bug in nvf.
• I have checked the issues tab and confirmed that my issue has not yet been reported. I understand that my issue will be closed if it is a duplicate.

Description

So many treesitter plugins and treesitter itself changed from the master to the main branch (NixOS/nixpkgs@71f1b82), and while doing that, they had a major rewrite of these, which makes the new main branch broken/incompatible with old use cases.

Nixpkgs should have a vim.nvim-treesitter-legacy package, but it seems like that's still stuck in review, so no chance for a quick hotfix (NixOS/nixpkgs#472119)

Since there was no issue yet, I just wanted to create this issue for tracking and awareness.

Please let me know if i can do more digging or add more logs/infos so i can help with this issue.
Other than that, I hope you had a great start into the new year, and thanks for taking a look into this! :)

Installation Method

Installation Method (Other)

Probably all install methods are affected?

nvf Version

master (flake)

Reproduction steps

1. Update flake
2. Deploy/rebuild
3. Open nvim

Expected behavior

Same as before, working as expected

Actual Behavior

Big fat error message, and most stuff doesn't work anymore since the init.lua is broken since the .config option doesn't exist anymore or something like that

BTW, I see docs recommend installing grammars using nvim-treesitter.builtGrammars. However, it does not install queries now, so you should use nvim-treesitter.withPlugins

[alfarelcynthesis]

For anyone experiencing this runtime error (on the most recent as-of-writing nixos-unstable build):

• (Untested but should work) For the nixos/home-manager modules, you should stick to a nixpkgs version like cad22e7d996aea55ecab064e84834289143e44a0 or c0b0e0fddf73fd517c3471e546c0df87a42d53f4 until this is fixed (anything before these also works: hydra).
• For the standalone package, provide pkgs made from the same version of nixpkgs as nvf uses (currently dc205f7b4fdb04c8b7877b43edb7b73be7730081), or use one from before the nixpkgs update, like those above, to neovimConfiguration. You should probably also stop overriding the input/override it to the same version so that nvf isn't mix-and-matching nixpkgs versions, until this is fixed.

You might have to do a bit more tweaking if you use overlays extensively.

(Also, this isn't really a bug in nvf, nixpkgs just swapped nvim-treesitter out from under it and it doesn't support the newer version yet.)

@alfarelcynthesis would appreciate some more specific magic and less handwave. I for one is not able to translate from what you write to actual nix code. thanx for help so far and thanx in advance for more specifics

You can set the nixpkgs version like this in your flake.nix (I'm assuming you're using flakes):

inputs = {
    # Nixpkgs
    # nixpkgs.url = "github:nixos/nixpkgs/nixos-unstable";
    nixpkgs.url = "github:nixos/nixpkgs/cad22e7d996aea55ecab064e84834289143e44a0";

    # neovim
    nvf.url = "github:NotAShelf/nvf";
    nvf.inputs.nixpkgs.follows = "nixpkgs";
};

[helgeu]

@alfarelcynthesis nvm. I think I nailed it myself with the following:

{
  description = "Initial MacOs setup";

  inputs = {
################# The following line should be working
    nixpkgs.url = "github:NixOS/nixpkgs/cad22e7d996aea55ecab064e84834289143e44a0"; 
...
}

seems to work even.

thanx again

thanx to @nicobonada too beating myself with a minute or so :)

[helgeu]

@nicobonada @alfarelcynthesis does the use of nvf.inputs.nixpkgs.follows = "nixpkgs"; mean I could have different setups with several versions of nixpkgs at same time?

@nicobonada @alfarelcynthesis does the use of nvf.inputs.nixpkgs.follows = "nixpkgs"; mean I could have different setups with several versions of nixpkgs at same time?

You can add an input with a different name and have nvf's nixpkgs input follow that one instead:

inputs =  {
  ...
  nvf.url = "github:notashelf/nvf";
  nvf-nixpkgs.url = "github:NixOS/nixpkgs/cad22e7d996aea55ecab064e84834289143e44a0";
  nvf.inputs.nixpkgs.follows = "nvf-nixpkgs";
};

This one works for me. Since my flake exposes a package using the standalone method I also need to change the pkgs arg passed to the nvf wrapper function:

nvf.lib.neovimConfiguration {
  pkgs = inputs.nvf.inputs.nixpkgs.legacyPackages.x86_64-linux;
  modules = [ ... ];
}).neovim;

(Yes, technically just using pkgs = inputs.nvf-nixpkgs.legacyPackages.x86_64-linux would also work but this one requires less fixing when I go back to having nvf follow nixpkgs unstable later)

[NotAShelf]

#1316 migrates also the textobjects plugin.

I have also ended up reverting to builtGrammars, because I'm not exactly sure what `grammarPlugins is if I'm being honest and I don't have a recent enough version of Nixpkgs checked out to go and trace it. That should not cause any breakage, but testing is appreciated. I'm on limited bandwidth, so those changes are mostly blind.

If you have issues with syntax highlighting, changes are #1316 addresses it.
