TreeSitter causes hard freeze

[TheSunCat]

⚠️ Please verify that this bug has NOT been reported before.

• I checked all existing issues and didn't find a similar issue

Description

Deleting a word in a C++ source file entirely freezes Neovim, requiring its process to be killed. My configuration: https://git.allpurposem.at/mat/Computer/src/branch/main/hm/modules/vim

This is likely due to tree-sitter/tree-sitter#3930, which is fixed by NixOS/nixpkgs#368952 .
Can anything be done from the nvf side in the meantime?

👟 Reproduction steps

This file repros it for me:

class test{
    Node* pNode{ nullptr };
};

Deleting pNode in any way causes a freeze.

👀 Expected behavior

Not freezing

😓 Actual Behavior

Freezing

we'll wait for NixOS/nixpkgs#368952 to get into unstable then bump our inputs

Do you know how much time it usually takes for a new package to be included into unstable branch?

[NotAShelf]

Usually PRs take 3-5 days to propagate into nixpkgs-unstable, which nvf follows.

This PR targeted staging, which may take a lot longer (on the order of a month)

I decided to install nvim binary from releases page, this fixed an issue for now, so you can try this approach as well. I'll switch back to nix version once it will be fixed

[NotAShelf]

We were discussing alternatives for the TS issue, but the best option for now might be to roll back nvf's flake input to before the tree-sitter regression was caused, most likely before the latest Neovim version bump.

I will look into a more streamlined alternstive for managing TS and friends if this becomes a reoccurring theme.

Tree-sitter bump finally got merged into master.
