#### Example: A `nix` class that propagates settings to NixOS and HomeManager
155
155
156
+
This can be used when you don't want NixOS and HomeManager to share the
157
+
same pkgs but still configure both at the same time.

#### Example: An `os` class forwarding to NixOS and nix-Darwin
184
+
185
+
This forward class can be useful for settings that are common to both
186
+
`nixos` and `darwin` classes.
187
+
188
+
```nix
189
+
os-class = { host }: { class, aspect-chain }: den._.forward {
190
+
each = lib.singleton true;
191
+
fromClass = _: "os";
192
+
intoClass = _: host.class;
193
+
intoPath = _: [ ]; # Forward at Top-Level
194
+
fromAspect = lib.head aspect-chain;
195
+
adaptArgs = lib.id;
196
+
};
197
+
198
+
199
+
# enable on all hosts
200
+
den.ctx.host.includes = [ os-class ];
201
+
202
+
# usage
203
+
den.aspects.my-laptop = {
204
+
nixos = {}; # nixos specific options
205
+
darwin = {}; # darwin specific options
206
+
207
+
# both on nixos and darwin
208
+
os = { pkgs, ... }: {
209
+
environment.packages = [ pkgs.hello ];
210
+
};
211
+
};
