Overlay support?

[LEXUGE]

Nice work done!
I wonder if we can have overlay support? This can make things much easier to deploy (and cleaner).

Thanks again for your impressive work.

Can you explain why it makes things easier or cleaner? From thinking it over in my head, and having used nixpkgs-wayland as an overlay, their usage is fairly similar. And to me at least, pulling one package from another package set is conceptually simpler than learning how overlays compose.

That having been said, it would be relatively easy to add...

I guess the overlay would make more sense if I added the rest of the firefox bin outputs.

[LEXUGE]

Because I am in favor to not use specialargs to pass in inputs which would be required without overlay. Also, as you said, it is making sense with multiple bin presented.

On top of that, overlay is also an choice for other people as well,

[colemickens]

I see. I still configure my overlay down inside my system config, but I see what you're saying if you apply the overlay at the top.

Makes sense, I'd take a PR or I can get to it sometime. :)

Now can we use it ?

[colemickens]

I am going to leave this open just because I don't think you can actually overlay this yourself since you'd only have access to a system-specific derivation. I do think there's a tiny slight different usage that can be unlocked offering up the overlay and it matches what I do in nixpkgs-wayland anyway.

Still, unfortunately, not a priority. And as I indicated in the other issue @alienzj, this shouldn't block you.

@colemickens Thanks. Let me try the method you indicated in the other issue.

Have you been able to use this with home manager, without overlays? Afaik inputs can't be passed as easily to home manager, while it's trivial to share the pkgs.

[colemickens]

I use home-manager as a nixos module, and can use inputs. I don't use an overlay though, I directly access the package from this flake's outputs.

It looks like home-manager has a extraSpecialArgs option that you can use to propagate inputs to home-manager modules, similar to how folks do with specialArgs and nixos modules.
