I know I'm repeating myself, but "why"? The r-ryantm can already autoupdate this, without this script.

[otavio]

I don't think it can @ajs124.

With this in place, I can run:

nix-shell maintainers/scripts/update.nix --argstr package anydesk

[shyim]

It can update it. We had already few prs from it

[otavio]

If it can, we ought to add it to the default upgrade.nix script so people can use it as a single point to upgrade their packages.

[otavio]

So, how I can upgrade it using upgrade.nix script?

ping?

@otavio its default behavior is to check repology.com and check to see if there's a version difference, and attempt to build by substituting the new version. https://repology.org/project/anydesk/versions

So currently it has to wait for another repo to update it, then we will follow suit.

cc @ryantm if I'm wrong

I think having a script which is more closely reflects the "source of truth" is beneficial though
