Macos and non-Nixos Linux working configuration?

[rhodee]

I had a question regarding how to setup multiple machines. I am looking to manage one macos and one Pop!OS machine using nixos-unified. I can get each working independently, but I would like to create a config which can setup home-manager for both.

My current config follows the patterns laid out in the templates here:

.
├── configurations
│   ├── darwin
│   │   └── mac.nix
│   └── home
│       └── rhodee.nix
├── flake.lock
├── flake.nix
└── modules
    ├── darwin
    │   └── default.nix
    ├── flake-parts
    │   ├── activate-home.nix 
    │   ├── devshell.nix
    │   └── toplevel.nix
    └── home
        ├── all
        ├── default.nix
        ├── editor
        ├── fonts.nix
        ├── gc.nix
        ├── git
        ├── linux.nix
        ├── macos.nix
        ├── nix-index.nix
        └── packages.nix

On Linux I need to have modules/flake-parts/activate-home.nix present otherwise nix run fails. However when I have this file in the same directory on my Mac, the build result passes but certain programs stop working and I see logs I would have expected only in Linux environments.

How can I structure my configuration such that it works for both OS environments in the same repo? Is it possible to only trigger activate-home.nix only on linux instead of in all environments?

The quick answer for now is:

Delete activate-home.nix, and run nix run . $USER@ on PopOS while running nix run on macOS.

But yes, a proper generic solution here is needed so that nix run works for all platforms. Let me think about this. I suppose we can have the activate script inspect the system type and act accordingly.

Thanks @srid. This projet and its previous iteration have been great for my productivity, thank you. I will make the update in my dotfiles.
