 MOVED TO n4ch7@n3831.net | whats the nixos version of home.file? i only find environment.etc | 16:23:07 |
 Robert Hensing (roberth) | Not sure I understand your problem description, but if you were adding options just to forward in-submodule metadata like options or _module to the parent, you could use valueMeta instead. | 16:46:50 |
| Robert Hensing (roberth) | Reason to merge the two operations is so that they can share computations. That's somewhat separate from the valueMeta addition | 16:47:37 |
 hsjobeki | I guess he is referring to seperate out the check, because freeformType is just calling merge without check | 16:48:01 |
| Robert Hensing (roberth) | They were combined into a single change to maximize the utility of having a v2 | 16:48:05 |
| Robert Hensing (roberth) | oh that... | 16:48:28 |
| hsjobeki | Though i am not sure what the benefit of merging without checking is. Checks are usually shallow and shouldnt change the lazyness. If the value is not of the expected type, merging it would also fail | 16:50:33 |
| Robert Hensing (roberth) | If you want merging without checking, you can still construct a type that achieves that | 16:51:02 |
| Robert Hensing (roberth) | But yeah, generally the check is simple because otherwise you're inducing unnecessary strictness, as in non-laziness | 16:51:36 |
| Robert Hensing (roberth) | => infinite recursions | 16:51:54 |
| hsjobeki | Do you suspect a breaking change in lazyness between just merge and checkAndMerge ? | 16:54:48 |
| hsjobeki | We dont have any reports, or at least i didnt get pinged in any issues regarding that. | 16:55:47 |
| MOVED TO n4ch7@n3831.net | do i have to use systemd.tmpfiles? | 16:56:55 |
 Matt Sturgeon | In reply to @n4ch723hr3r:nope.chat
do i have to use systemd.tmpfiles? This room is for discussing the module system itself, not NixOS and its options. You want https://matrix.to/#/!6oudZq5zJjAyrxL2uY:0upti.me | 17:16:25 |
 vivekanandan_ks | Hi All,
What do u all think about the flake-parts?
Is that somehow making the current modules system better?
Or it helps the current modules to be easy? | 17:59:32 |
| Matt Sturgeon | Flake-parts uses the module system to construct flake outputs. Just like how NixOS uses the module system to construct an OS, or Home Manager uses the module system to construct a user's profile.
I'm not sure what you're asking about how it interacts with "current" modules, or what you mean by "current" 🙂 | 18:20:35 |
| MOVED TO n4ch7@n3831.net | i think hes asking for an opinion about flake.parts | 18:43:44 |
| 26 Nov 2025 |
| hsjobeki | I'd say i don't have a general opinion.
If you develop a third party nix library that other people depend on every input that you have adds to their dependencies as well.
That is how flake dependencies behave. And everyone needs to pin nixpkgs-lib of flake-parts otherwise you get their version, which is an extra 50MB download.
Other than that if you are using it for your own project that doesn't have dependents it is in my opinion a good UX, which lets you leverage the module system to decompose the components of your flake. | 16:33:29 |
| Robert Hensing (roberth) | it now uses a small lib-only flake fwiw, but the override still makes sense to have | 16:39:27 |
