tree-sitter.buildGrammar - error: cannot coerce a set to a string

[skrobul]

I was trying to switch to the neovim-nightly, but I am not able to because of this error when attempting to nixos-rebuild

at /nix/store/wzx1ba5hqqfa23vfrvqmfmkpj25p37mr-source/pkgs/by-name/ne/neovim-unwrapped/package.nix:175:20:

       error: cannot coerce a set to a string

I searched for a potential solution and stumbled upon #591 where @antoineco suggested adding inputs.nixpkgs.follows = "nixpkgs"; but it made absolutely no difference for me (same traceback was produced).

My exact configuration at the time when this happens is available here:

• flake.nix
• home.nix

Is there anything I am doing wrong here? I'd appreciate any help or suggestions

[antoineco]

@skrobul your repo seems private. Maybe your nixpkgs input is 24.05 instead of nixpkgs-unstable? If that's the case, you need to remove the follow, because this overlay works against the unstable branch.

@antoineco - thanks and apologies, I have now made the repo public so you can see whole file.

Following your suggestion I have also tried:

  inputs = {
    nixpkgs.url = "github:nixos/nixpkgs?ref=24.05";
    nixpkgs-unstable.url = "github:nixos/nixpkgs/nixpkgs-unstable";
    neovim-nightly-overlay = {
      url = "github:nix-community/neovim-nightly-overlay";
      inputs.nixpkgs.follows = "nixpkgs";
    };

as well as

  inputs = {
    nixpkgs.url = "github:nixos/nixpkgs?ref=24.05";
    nixpkgs-unstable.url = "github:nixos/nixpkgs/nixpkgs-unstable";
    neovim-nightly-overlay = {
      url = "github:nix-community/neovim-nightly-overlay";
      inputs.nixpkgs.follows = "nixpkgs-unstable";
    };

and

  inputs = {
    nixpkgs.url = "github:nixos/nixpkgs?ref=24.05";
    nixpkgs-unstable.url = "github:nixos/nixpkgs/nixpkgs-unstable";
    neovim-nightly-overlay = {
      url = "github:nix-community/neovim-nightly-overlay";
     };

and all of them end up with exact same traceback :(

[antoineco]

@skrobul the flake you linked doesn't seem to be applying the overlay. Anyway the trick for me was to apply it on top of nixpkgs-unstable: https://github.com/antoineco/dotfiles/blob/aabe14063e89265fe4c2a378d31f57d33fed4e46/nix/flakes/system/flake.nix#L38-L42

Since you are using two different revisions of nixpkgs inside your flake, you have to be careful not to be accidentally applying it on top of nixos-24.05.

[skrobul]

I thought this part

({ config, pkgs, ... }: { nixpkgs.overlays = [ overlay-unstable inputs.neovim-nightly-overlay.overlays.default]; })

was applying the overlay, but looks like I need to do some more reading as I'm genuinely lost here.

[willruggiano]

See #533

[willruggiano]

Overriding inputs won't make much of a difference when using overlays. If you absolutely must use the 24.05 branch then I suggest you directly access neovim-nightly via the flake's outputs, e.g.

environment.systemPackages = [inputs.neovim-nightly.packages.${system}.default];

[skrobul]

See #533

Thanks, I did - my take-away from this issue was that I need to update my nixpkgs so I have ran nix flake update earlier, did I need to do anything else?

TIL

That did the trick, THANK YOU so much 🙌🏻 I just now need to figure out how to make it work with home-manager.

For future reference if anyone gets the problem, here's what I did

1. Update flakes to pass inputs to configuration.nix as described here
2. Add the snippet @willruggiano posted above - it was just called inputs.neovim-nightly-overlay.packages... instead of inputs.neovim-nightly.packages.

[skrobul]

Making it work with home-manager was easier than I thought. Once again, big thanks guys, appreciate your help!

[glebdovzhenko]

Hey @skrobul could you please share your solution? The link is dead and I'm facing the same issue.

[skrobul]

@glebdovzhenko sure thing, this is a diff from a commit linked above (sorry didn't realise it's private repo):
