Interesting, thanks for your contribution!

I made some comments on your PR that need to be addressed before considering to merge.

Also, be aware that I’ll hold up on releasing this because the change in home-manager is not on the latest stable branch (25.05), as you can see for yourself. NixOS 25.11 is expected to be released in a few days, and home-manager should quickly follow and I’ll release a new version with your changes.

[nicolas-goudry]

Regarding backward compatibility, I think it should be better to use something like:

default = config.programs.git.userEmail or (lib.attrByPath ["settings" "user" "email"] null config.programs.git);
defaultText = "config.programs.git.userEmail or config.programs.git.settings.user.email";

This way, NixKraken supports both methods, since the old config format is deprecated, not removed yet.

Maybe also add a TODO note in the code to remember removing the compat or when old config keys are dropped entirely from home-manager.

You don't have to update the reference documentation, it's automatically handled in CI 🙂

[rhoriguchi]

Fair point to hold out till 25.11 is released. I run unstable, so I didn't think about people still running an older release.

[nicolas-goudry]

Thanks for fixing the format.

Don't mind the documentation CI error.

I’ll wait for the CI to pass and merge!

Thanks again for the fix 🙂
