External Art
When you need to use a module, overlay, or pass a value from one of your inputs
to the rest of your NixOS configuration, you can make use of a couple arguments.
It is encouraged to add external art directly in your flake.nix so the file
represents a complete dependency overview of your flake.
Overlays
External overlays can directly be added to a channel's overlays list.
flake.nix:
{
channels.nixos.overlays = [ inputs.agenix.overlay ];
}
These overlays will be automatically filtered by inspecting the inputs argument.
Modules
There is a dedicated nixos.hostDefaults.externalModules argument for external
modules.
flake.nix:
{
nixos.hostDefaults.externalModules = [ inputs.agenix.nixosModules.age ];
}
Home Manager
Since there isn't a hosts concept for home-manager, externalModules is just a
top-level argument in the home namespace.
flake.nix:
{
home.externalModules = [ doom-emacs = doom-emacs.hmModule ];
}
Note:
The optimal solution would be to automatically export modules that were created in your flake. But this is not possible due to NixOS/nix#4740.
