Is there a way of using the configuration settings for devShells?

[dmoonfire]

Over the years, I have an opinionated way of setting up my development projects through a Nix flake. There is also one that extends that to handle my writing projects and even one after that for a specific world setting.

In all of these cases, I'm basically emitting a lib.mkConfig function that sets up the various settings (like configuring conform, turning on rust or dotnet, etc.).

devShells = forEachSupportedSystem ({ system, pkgs }:
let
    config = inputs.mfgames-project-setup.lib.mkConfig {
        inherit system pkgs;
        conform.scopes = [ "cli" "website" ];
        rust.enable = false;
    };
in
{
    default = pkgs.mkShell {
        # Add in the required packages for the configuration.
        packages = [] ++ config.packages;

        # Add in the
        shellHook = ''
            ${config.shellHook}
        '';
    };
});

I've just recently switched mfgames-project-setup-flake to use flake-parts, but I'd love to know if there is a way of using the configuration setup to use that instead of mkConfig.

# I figured out how to get this part so it can get the configuration value.
mfgames-project-setup.conform.scopes = ["cli" "website"];
mfgames-project-setup.rust.enable = true;

devShells = forEachSupportedSystem ({ system, pkgs }:
{
    default = pkgs.mkShell {
        # Add in the required packages for the configuration.
        packages = [] ++ some-magical-property-that-generates-the-required-packages;

        # Add in the
        shellHook = ''
            ${some-magical-property-that-generates-the-shell-hook}
        '';
    };
});

Even if I need a let shellHook = inputs.mfgames-project-setup.lib.shellShell or something, it would make things cleaner.

Thank you.
