The flake utilities are too specific. Not going to contribute further crap in the world. ;p

It will automate some of the things such as making the last component
|
|
of the path as the hostname.
|
|
|
|
This is a wrapper for `nixpkgs.lib.nixosSystem`.
|
|
|
|
Signature:
|
|
path -> attrset -> NixOS configuration
|
|
Where:
|
|
- `path` is a path to a Nix file for the host; the basename of the file
|
|
is also used as the hostname
|
|
- `attrset` is the attribute set to be included in the host configuration
|
|
Returns:
|
|
An attribute set from the `lib.nixosSystem` from `nixpkgs` flake.
|
|
|
|
Example:
|
|
mkHost ./hosts/june {}
|
|
=> { ... } # NixOS configuration attrset
|
|
*/
|
|

|
|

/* Create a home-manager configuration for use in flakes.
|
|
|
|
This is a wrapper for `home-manager.lib.homeManagerConfiguration`.
|
|
|
|
Signature:
|
|
file -> attrset -> homeManagerConfiguration
|
|
Where:
|
|
- `file` is the entry point to the home-manager configuration.
|
|
- `attrset` is the additional attribute set to be insert as one of the imported modules minus the attributes used for `home-manager.lib.homeManagerConfiguration`.
|
|
Returns:
|
|
A home-manager configuration to be exported in flakes.
|
|
|
|
Example:
|
|
mkUser ./users/foo-dogsquared {}
|
|
=> { ... } # A home-manager configuration set.
|
