How can I run the updateScript of personal packages?

Help

I have a few packages in a personal repository that I’ve been occasionally updating manually. I see that nixpkgs has some tooling around passthru.updateScript that helps automate this.

Is there a way for me to use that in my own repository? I’d love to be able to set e.g.

passthru.updateScript = gitUpdater { };

and then just run some command to update the package locally.

It is definitely possible, I do it in my personal repository using a custom script that calls update.nix from Nixpkgs. The most important thing is to pass overlay containing your packages to update.nix and some update scripts may require having packages available as top-level attributes from default.nix (which will require extra boilerplate when using flakes).

Though not all updateScripts will work out of the box – adjustments to the detection of edited file path might be needed.

$ ./tasks/update
