Violation of the flake schema

[Gerg-L]

Was trying to demonstrate to a newer nix user how to figure what method to use for configuration of a nix project without documentation (all of them) and nix flake show does not work on your flake making this much harder

$ nix flake show github:nix-community/nixvim
github:nix-community/nixvim/6be28a941b39a7cbe4d34b577bd095548f5d1e15?narHash=sha256-3kL4E0Ff9TCvRNxwINzklupY7dcTpl89jTg0PGfBCJc%3D
├───checks

error: 'checks.aarch64-darwin' is not an attribute set

nixvim/flake-modules/packages.nix

Lines 13 to 14 in 6be28a9

	# Test that all packages build fine when running `nix flake check`.
	checks = config.packages;

found the culprit

[MattSturgeon]

The wiki documents the schema as

checks."<system>"."<name>" = derivation;

Which is what the code you linked should be doing.

config.packages is the (per-system) result of calling docs/default.nix, which is an attr set containing options-json, man-docs, & docs.

Which should result in the flake output:

checks.<system>
  - options-json
  - man-docs
  - docs

[Gerg-L]

So the packages. Output is wrong too

This seems strange, because for example it is correct for x86_64-linux:

nix repl .
nix-repl> :lf .
nix-repl> builtins.typeOf checks.x86_64-linux
"set"

I am not using a darwin machine, so I am not able to show the schema for it. What machine are you using?

The error I encounter is:

Which is a known issue #1154 but there is not much we can do here, we would need something like NixOS/nix#6530

[Gerg-L]

nixvim/docs/default.nix

Lines 7 to 17 in 72ff148

	pkgsDoc =
	import
	(pkgs.applyPatches {
	name = "nixpkgs-nixvim-doc";
	src = pkgs.path;
	patches = [ ./either_recursive.patch ];
	})
	{
	inherit (pkgs) system;
	config.allowUnfree = true;
	};

here's the IFD

[traxys]

Yeah we know about it, but the alternative is not desirable
