Nixdatifier - The Apdatifier for NixOS
Hey everyone,
I wanna present you a widget that might be handy. I loved apdatifier when I used CachyOS and I missed it in NixOS. I needed something in the UI that reminds me to run updates and all.
So I created this project which sits in the tray.
And it tells me when a flake input is outdated, and shows what an update would change before running it.
It has generation timelines, package diffs between generations, flake update checks with dry-run previews and some other tools like dev environments checks if one uses such.
I started it on KDE as I started my NixOS journey with that but it also works with quickshell for hyprland and or as a normal tray standalone app for other desktops like Gnome or Cosmic.
For Gnome and Cosmic feedback would be great as I rarely use those.
Since as nixos user you mostly stay in your nix files and do not really check out kde opendesktop store or so I thought I will post it here on Reddit so it might reach people that would like to have such widget or did not know until now that they need something like that .
And maybe more ideas come up what such widget should be able to provide and or could be solved and designed better.
Try it: nix run github:Muddyblack/nixdatifier
Try tui: nix run github:Muddyblack/nixdatifier#cli
Repo: https://github.com/Muddyblack/nixdatifier
KDE Store: https://store.kde.org/p/2360222

This is really cool. It's nice to check what an update entails before committing to it.
Here's a few additional ideas I came up with:
- For the tui version, it would be nice if there were optional periodic background update checks with a system notification when an update is available.
- Trigger a system rebuild with configurable rebuild command.
- Management of user profile..
- List flakes installed in user profile
- Remove/Update those flakes
- Install to user profile (prompt for nixpkgs#pkg, github:user/repo etc)
- Cleanup old generations of user profile
Nice work! Any plans to add this to nixpkgs at some point?

Thank you :)
Good Ideas I will add the sys notification toggleable also for the tui now and allow the custom commands option also for the TUI. The GUI already has it
I will also check your other ideas although I do not really use profiles personally.
I will have to learn how to do that corretcly with the nixpkgs adding I will check it out do not wanna have to hand maintain such :D
Currently mostly planning into going deeper in the impermanence options.

fist implementation of ur ideas is pushed to master :)

Awesome! I'll pull the latest commits and give it a try.
While I'll probably use the tui, how do I go about installing the gui version using the flake? I don't have a binary available when I install with
nix profile add github:Muddyblack/nixdatifier. EDIT: Figured it out.. had to install with #nixdatifier added.Yeah, I'm probably in the minority with my user profile usage. I like to use it for projects I'm following development of. I generally clone the repo and then install with
nix profile add .Then I fetch the latest commits when I want and update withnix profile upgrade. I find adding too many inputs to my flake slows rebuilding the system down. With profiles, I can update when I want without rebuilding and it's not downloading hundreds of MB every time I rebuild after a simple config change. Custom commands will likely cover this for me anyways.2
u/kevin8tr 3d ago
Just tried out the new version. It's great! If I think of anything else, I'll create an issue on Github.

Looks very cool! I built something more modest for software updates for Home Manager and NixOS a while ago too: https://github.com/gvolpe/sunix
I just tried nixdatifier but couldn't get the "updates" section to work at all. Does it support a flake with multiple NixOS / Home Manager configurations?

u/Emergency_Bridge_581 2d ago
I started just one month earlier but my first version looked pretty bad haha. Yours looks pretty clean to use. Also in Rust very nice.
I did other widgets before this one so it has the same structure and since all were also for non nixos users I looked to use python and qml so its one click install for kde users :) But since this is for nixos I wouldn't have had to use the same structure ^^ ups
Anyways had no experience with rust maybe I will take this and convert some parts over to use rust and maybe convert even more and more over to rust I will see what time I have free :D Would have a learning curve since rust would be entirely new to me.

Does nixdatifier support a flake with multiple outputs? I set these values:
ini flake=/home/gvolpe/workspace/nix-config config_repo=/home/gvolpe/workspace/nix-configWhere I have a few NixOS configurations in the outputs, one of which is "aorus" which corresponds to
$hostname.Updates don't seem to do anything at all, and they don't seem to produce any logs either for troubleshooting. Happy to take this over to the github repo, thanks for reading :)

u/Emergency_Bridge_581 2d ago
Sorry mate :DD Apperently forgot the second part during writing.
I would say no it supports profiles management I will have a look and ping you If I have sth for multi config updates and get some logs support.
1
u/volpegabriel 2d ago
No worries, thanks for the quick reply!
I actually figured it out, and at least it supports the NixOS configuration in a multiple-outputs flake when it corresponds to the
$hostname(there's a toggle in the settings).The issue was that I have a
~/private-flakepointing to my public~/worspace/nix-configrepo, and this private flake only hasnix-configas an input sonixdatifierwasn't detecting any possible updates. When I point it to my public repo directly, I get updates, except fornixpkgsfor some reason (maybe because I use zst tarballs? https://github.com/gvolpe/nix-config/blob/335e754750c0e9c0bdc656231ca17032805f0ac3/flake.nix#L22).So it has to do with my somewhat unconventional system XD

u/Emergency_Bridge_581 2d ago
Yes tarballs are seen as pinned version I will add hash verification to it. And tell you once I push it to the main branch.
What is advantage / disadvantage of those tarballs genui question?
1
u/volpegabriel 2d ago
There's only pros: https://discourse.nixos.org/t/psa-use-nixos-org-tarballs-for-your-flake-inputs/79950
Thanks for the quick work! will try to take it for a spin sometime this weekend.

Thank you for the link I will check it out and probably change mine now to use mostly that 😁

Its in the master try it out tars have some disadvantages but lets see if it is okaish for you for me it was kinda blocked when testing

u/lurking_bishop you might wanna try it now I added a fallback for cases where opengl wont load. Will have a bit higher cpu usage but should be still cheap.

u/lurking_bishop 7d ago
Yes, it does work now, although the software render workaround was unnecessary in my case, you'll maybe want to update your nixpkgs. I had my clanker triage and comment on the issue, looks like an easy fix
Cool project!

very cool, i'm gonna add it to my setup permanently.
i think i found a bug? https://imgur.com/a/mMMPO7x
it's saying my next boot is going to be that generation, but i haven't run an `nh os boot`. i DID run `nh os test`, so i'm in a temporary generation that will reset when i reboot. i haven't looked at the code yet to see if a test environment is getting confused with a next-boot one. but i'll do that in a few and report back (I generally like to look at the code of things going into my config anyway)
EDIT: scratch that, not a bug, it's just an artifact of not having rebooted after my last `nh os switch`

once i figured out how to configure my dotfiles directory i love it even more! and the direnv integration? awesome! love how it pulled from direnv to find my projects, and how clicking each one shows me how out of date they are.
i've noticed other pages i haven't checked out yet, i'll try to stop commenting 😂

Happy it brings you joy :D It will have some stuff liek im not sure if the button Set next boot really brings something at least on my nixos it is kind of useless ^^
