The option `self` does not exist - when attempting to add a new top-level flake output and leveraging it about flake-parts

[roberth]

Hi @x10an14,

The way flake-parts uses the module system is more complicated than NixOS, so don't despair :)
It seems that I've underestimated the difficulty of developing new modules. I'll make an attempt at filling in some of the missing documentation about the module system specifically.

at some times/places these are different configs,

That deserves an article of its own.

self is only a module argument, not an option, let alone an option you can define a value for. The value of self comes directly from Nix.

In order to make your allowedUnfreePackages global, it doesn't have to be in flake, but you do have to declare it, as it seems that you want to merge definitions from multiple places.

What you're trying to solve is not a unique problem though. I think the right solution is to have a better nixpkgs module, and perhaps also a home manager module that integrates with the pkgs constructed by that nixpkgs module.

(...) I'll close this, but feel free to ask questions.

Thanks!

Aren't you invoking those functions from within a scope that has the flake-parts config? You could then forward it.

I already tried asking for guidance/help with that over at your Matrix channel, but I didn't feel comfortable continuing the discussion to be honest.

I felt there was too much of a disconnect between the respective perspectives of the ones in the know, and the newbie who knows next to nothing (me). It didn't make me feel as if I could ask for help without becoming too much of a bother.

To be clear; I suspect no ill will - a lot gets missed/misunderstood with written chat.
I just didn't feel like it was possible to communicate due to lack of what I'd call a "common platform of understanding".

I still do not understand the differences/similarities/intricacies of config from within the contexts of the referenced function invocations here, and the config.flake mentioned in your documentation. I have no idea what I don't understand, which makes it nigh impossible for me to know what questions to ask, let alone how to formulate them correctly.

(And this from a ~2yrs nix(os) user who has experience from writing and using of options with the nixos/home-manager config specialArgs variable).

I just know that at some times/places these are different configs, and at others they are not. Not really managed to find examples showing this interplay between them/how to leverage config.flake.

I solved it without flake-parts for now. Subscribed to #74 for progress updates.

Ideally, I wish to assign this allowedUnfreePackages option to a flake-global variable, instead of config.
(Due config only being available after home-manager.lib.homeManagerConfiguration or nixpkgs.lib.nixosSystem invocations).

Looking forward to it!'
