@timdeh:matrix.org@timdeh:matrix.orgThat's what nixpkgs.overlays does under the hood19:26:59
@timdeh:matrix.org@timdeh:matrix.org so nixos has a nixpkgs.pkgs option where you can just build the global pkg set and it will be passed in to every module. Home-manager doesn't seem to have this, but it does have nixpkgs.config and nixpkgs.overlays, which would be applied to the underlying package set and passed in to every module as pkgs 19:27:56
@d4hines:matrix.orgd4hines I get dependency injection but this seems convoluted. It also seems purely conventional - its' just convention that the prop called nixpkgs.overlays gets picked up by home-manager, applied to nixpkgs, and the result is passed to each module, right? 19:30:35
@d4hines:matrix.orgd4hinesAm I missing a piece, or is it something I get used to as I go along?19:32:27
@ultranix:matrix.orgultranixI still don't understand how to add profiles/suites to a home.users.<user> in flake.nix, 19:32:53
@timdeh:matrix.org@timdeh:matrix.orgare you already familiar with how to use them for nixos? it should be basically the same19:34:22

I'm not sure if this example would be helpful to you but here's I'm doing it https://github.com/d4hines/devos/blob/hope/flake.nix#L103 		19:34:26
@d4hines:matrix.orgd4hines
In reply to @timdeh:matrix.org
so basically the way you have it now, you could just add a nixpkgs.overlays = [ self.overlay ]

The wiki lists overlay as a valid attribute of flakes; however, I'm getting this error:

error: flake 'git+file:///home/d4hines/repos/beth' has an unsupported attribute 'overlay', at /nix/store/9cdyiyw5333969j5rhyrc3112kl2wkcv-source/flake.nix:4:3

@d4hines:matrix.orgd4hineshttps://nixos.wiki/wiki/Flakes#Output_schema19:37:21
@d4hines:matrix.orgd4hinesOh, it's an attribute of the output object19:38:08
@timdeh:matrix.org@timdeh:matrix.org oh yes, I didn't notice that. The top-level attributes in a flake.nix should only be description inputs outputs and nixConfig. 19:39:52

@timdeh:matrix.org@timdeh:matrix.org outputs being the meat of it 19:40:11
@yusdacra:nixos.devyusdacrai'm getting this with latest nixpkgs-unstable19:40:17
@yusdacra:nixos.devyusdacrai guess the patches are out of date now19:40:24
@timdeh:matrix.org@timdeh:matrix.org I think the patches are only for the nix in the shell though right David Arnold (blaggacao) 19:41:01
@timdeh:matrix.org@timdeh:matrix.orgI just updated nix to master since I recently merged a version bump and it's working on my system. Even with nix-dram applied19:41:34
@yusdacra:nixos.devyusdacrahmm19:41:49
@yusdacra:nixos.devyusdacrai think i can build the system fine19:42:19
@yusdacra:nixos.devyusdacraits just the devshell19:42:23

In reply to @d4hines:matrix.org
Right. I want to do this without libraries first, then refactor as necessary.
I empathically understand the impetus. However, if you ask me, it might be easier the other way round.. 🙂 		19:44:06

I still don't understand how to add profiles/suites to a home.users.<user> in flake.nix,

if you are using master, you should have some suites under home.importables.suites, then you reference these in a user under ./users/kraftnix/default.nix or ./users/kraftnix.nix and do something like

  home-manager.users.kraftnix = { suites, ... }: {
    imports = with suites; base ++ tokyo-night;
    ...
  };

where the above pulls in a suite I have called base and tokyo-night, at least that's how I use user profiles

yeah, it's just used in the shell because of the follows bug. Hopefully they merge that PR soonish so we can remove the patches all together 		19:45:51

you might also have a complementary look at: https://github.com/divnix/digga/tree/main/examples -- they are very minimal. 		19:46:35
@kraftnix:matrix.org@kraftnix:matrix.orgi was not aware digga had that section, nice19:48:06
@ultranix:matrix.orgultranixthanks. some of the examples had removed home-manager.users.<user> from the users/<user>/default.nix and replaced it with just the username. so its confusing19:48:07

flakes only have a weak schema. some attrs are better known than others. any attribute is fine. none has magic semantics beyond a bit of cli ux sugar 		19:48:25

yeah first I was looking in digga/devos for an example like how I manage my own users, and found the default root/nixos users don't do it like I do 		19:48:52

yes but this is only true for the outputs schema. An unexpected attribute in the top-level will result in an evaluation error 		19:49:21

Is that the follows patch? -- let me know.. 		19:49:40
