nerdshade 🕶

Calculates outside brightness based on location and local time OR based on fixed schedule.

Brightness is translated into a color temperature and gamma value and handed over to hyprsunset.

Color temperature and gamma values transition smoothly for an hour (configurable) during sunrise and sunset (or wakupe/bedtime respectively).

Actual calculation of sunrise/sunset times is done by the go-sunrise package.

Can be run in one-shot mode (default) or in a loop.
