@sarahec sorry for ping, but do you know how to find a cargoHash sha256 for this package??

[SigmaSquadron]

Looks like upstream's Cargo.lock is extremely old, and the fetcher is unable to parse it because it lacks the checksum field found in newer Rust projects. You can ask upstream to update their lockfile, or generate a patch yourself.

Are you sure you want to add a project that's been unmaintained for over 4 years to Nixpkgs? Are there really no replacements for this?

Hm. That's actually a good point.

Well, I would like to have it upstream in nixpkgs because I want toggle feature in sketchybar.
I'm sure it will benefit others until something else is developed. I'll ask smudge to update the lockfile.

[sarahec]

I just tested in homebrew (which builds from source) and nightlight still works. I'm surprised as many other solutions have come and gone in the past few years.

[sarahec]

@aspauldingcode to answer you question, the process is:

1. set cargoHash to an empty string.
2. Build your package with nix-build. It will fail, and the failure message will contain the computed hash.
3. Paste the computed hash into cargoHash
4. Build again and it should work.

Thanks.
I thought I did it right. So it really is an outdate Cargo.lock that doesn't even contain the checksum needed to verify the hash

[aspauldingcode]

I'm leaning towards not merging this since it's not maintained. I'll probably fork it and maintain my own fork, then open a pr for that project instead.

[smudge]

I'd be more than happy to merge a PR that fixes the lockfile!

Also, I'd contend that a project doesn't always require commit activity in order to be considered maintained - since it still builds and works on all of my machines, I haven't had a reason to ship a new release in four years! 😅

I noticed your messages on the recent issues of that repo. Perhaps closing this was too hasty of a decision.

[sarahec]

I tested running cargo update --verbose on a fork of nightlight and it generally worked. You'll need to bump the edition field to 2024. You could update gio, time, and objc to their latest versions, but you will need to make corresponding changes to the code.

@aspauldingcode I don't know what your time looks like these days, but if you have the time this could be a valuable learning project.

[aspauldingcode]

@sarahec I ran out of storage space and taking several classes, waiting on my new laptop to arrive before I merge my fixes, but I made some changes to nightlight I'd like to share and I'm not abandoning this pr just yet 😄 thanks for heads up on cargo dependencies

[aspauldingcode]

Looks like I need cargo from unstable. Otherwise I cannot use cargo update after setting Cargo.toml edition = 2024.
I've managed to clear up some storage space but I was failing to rebuild due to this issue after a recent nix flake update invocation. I think it's fixed now upstream.

You could also back up to an earlier edition, just not all the way back to 2018.

Can’t build nor test it since I’m on Linux.

[aspauldingcode]

Brilliant suggestions.

[nicolas-goudry]

LGTM but as I said previously I cannot build nor test it since I’m on Linux.

Thanks for contributing!
