Automatically change to light and dark mode depending on your location.

Set up a simple config.yaml under your $XDG_CONFIG_HOME/blueblack file with

# Get your lattitude and longtitude through e.g. gmaps (https://support.google.com/maps/answer/18539?hl=en&co=GENIE.Platform%3DDesktop)
"lat": 23.2003
"lng": 31.1233
"update_days": 1

and change the update_days to something appropriate (e.g. 10 days).

When it's slightly past sunrise or sunset time (around 5 seconds), executable scripts inside XDG_CONFIG_HOME/blueblack/{dark,light}_mode will run automatically. Some examples are provided in the source code page

Internally, Blueblack will use the Sunrise-sunset API which is currently free. Please use this responsibly, so we can have free things.
