[NOTICE] Upstream breaking changes

[willruggiano]

If you've recently updated your system to depend on a recent commit (at least d659352) of this repository, you might encounter an error like that seen in #521. If you do, ensure that you have a recent nixpkgs package set (at least NixOS/nixpkgs@d5786c1).

There were a number of commits introduced upstream (i.e. nixpkgs) where breaking changes (and subsequent reverts) were made to the packaging of neovim-unwrapped (particularly as it relates to bundling tree-sitter parsers), for example; NixOS/nixpkgs@76ef4c7.

This advice applies particularly to those of you which override the nixpkgs input for this flake, e.g.

inputs.neovim-nightly-overlay.inputs.nixpkgs.follows = "your nixpkgs";

as well as those of you that use the flake's default overlay, e.g.

{
  nixpkgs.overlays = [
    inputs.neovim-nightly-overlay.overlays.default
  ];
}

[GaetanLepage]

@willruggiano should we know mark this as resolved ?

[willruggiano]

I would keep it open for a bit longer. There's been a few references to it recently

I am unsure if this is the same issue, but I get

[willruggiano]

Hard to tell without seeing how you're using the flake. It looks like you're trying to install neovim-qt?
