|
|
Recursively imports non-dendritic .nix files depending on their Nix configuration `class`.
|
||
|
|
|
||
|
|
This can be used to help migrating from huge existing setups.
|
||
|
|
|
||
|
|
|
||
|
|
```
|
||
|
|
# this is at <repo>/modules/non-dendritic.nix
|
||
|
|
den.aspects.my-laptop.includes = [
|
||
|
|
(den._.import-tree._.host ../non-dendritic)
|
||
|
|
]
|
||
|
|
```
|
||
|
|
|
||
|
|
With following structure, it will automatically load modules depending on their class.
|
||
|
|
|
||
|
|
```
|
||
|
|
<repo>/
|
||
|
|

|
||
|
|
non-dendritic.nix # configures this aspect
|
||
|
|
non-dendritic/ # name is just an example here
|

|
|

|
||

_nixos/ # a directory for `nixos` class
|

|

||
|
|
foo.nix
|
||
|

## Requirements

|
|

|
|
- inputs.import-tree
|
||
|
|
|
||
|
|
## Usage
|
||
|
|
|
||
|
|
this aspect can be included explicitly on any aspect:
|
||
|
|
|
||
|
|
# example: will import ./disko/_nixos files automatically.
|
||
|
|
den.aspects.my-disko.includes = [ (den._.import-tree ./disko/) ];
|
||
|
|
|
||
|
|
or it can be default imported per host/user/home:
|
||
|
|
|
||
|
|
# load from ./hosts/<host>/_nixos
|
||
|
|
den.default.includes = [ (den._.import-tree._.host ./hosts) ];
|
||
|
|
|
||
|
|
# load from ./users/<user>/{_homeManager, _nixos}
|
||
|
|
den.default.includes = [ (den._.import-tree._.user ./users) ];
|
||
|
|
|
||
|
|
# load from ./homes/<home>/_homeManager
|
||
|
|
den.default.includes = [ (den._.import-tree._.home ./homes) ];
|
||
|
|
|
||
|
|
you are also free to create your own auto-imports layout following the implementation of these.

||
|

# deadnix: skip

let

aspect.${class}.imports = [ (inputs.import-tree path) ];
|

in
|
||
|
|
if builtins.pathExists path then aspect else { };

den._.import-tree.provides = {
