#### Example: Platform Aware `homeManager` classes
254
+
255
+
This uses `pkgs.stdenv.isXYZ` to define `hmXYZ` classes,
256
+
because some hm configurations might be only available
257
+
on specific platforms.
258
+
259
+
```nix
260
+
hmPlatforms =
261
+
{ class, aspect-chain }:
262
+
den._.forward {
263
+
each = [ "Linux" "Darwin" ];
264
+
fromClass = platform: "hm${platform}";
265
+
intoClass = _: "homeManager";
266
+
intoPath = _: [ ];
267
+
fromAspect = _: lib.head aspect-chain;
268
+
guard = { pkgs, ... }: platform: lib.mkIf pkgs.stdenv."is${platform}";
269
+
adaptArgs = { config, ... }: { osConfig = config; };
270
+
};
271
+
272
+
den.hosts.x86_64-linux.igloo.users.tux = { };
273
+
den.hosts.aarch64-darwin.apple.users.tux = { };
274
+
275
+
den.aspects.tux = {
276
+
includes = [ hmPlatforms ];
277
+
hmDarwin = { pkgs, ... }: { home.packages = [ pkgs.iterm2 ]; };
278
+
hmLinux = { pkgs, ... }: { home.packages = [ pkgs.wl-clipboard-rs ]; };
279
+
};
280
