The option `shell.buildInputs' does not exist.

As of about a week ago, master now generates the following error for us during nix develop evaluation:

 nix develop

Our project is run from a flake and contains a shell attribute:

shell = {
  exactDeps = true;
  withHoogle = true;
  ...
  buildInputs = (with final; [
    # Temporary workaround for HLS issues until the next release.
    hls

    nixpkgs-fmt
    ...

I don't see any changes to the documentation that indicate buildInputs is no longer supported, so I'm assuming it's a bug?

I broke this when I added the shell arguments as a submodule of the project arguments. I forgot that anything we can pass to pkgs.mkShell can also be included (they are passed on here).

I think we need to add the following to the module in shell.nix:

• From pkgs.mkShell
  • name
  • inputsFrom
  • shellHook
• From mkDerivation
  • buildInputs
  • nativeBuildInputs
  • passthru

Is there any documentation that should be updated regarding this?

[billksun]

I'm lost, how do I include packages from nixpkgs in my dev shell then?
