ADD set backlight brightness according to time of day/sun

[allanlaal]

Details about the problem

I want the kb backlight to correspond on how bright it is outside to increase usability

since there isn't a brightness sensor in my kb, its best to set this using sun times (I live in scandinavia, so we don't have fixed sunset/sunrise times)

good library: https://github.com/risacher/sunwait

Thanks for the suggestion. That would be a good enhancement for the planned "Triggers" feature. To start with, I was thinking based on time (#272).

sunwait appears to be a C++ program, not a Python library. It seems like it can be used by creating a simple brightness.sh script and making this run as soon as you login (in "Startup Applications") like so:

#!/bin/bash
while true
do
    sunwait wait rise
    polychromatic-cli -o brightness -p 80
    sunwait wait set
    polychromatic-cli -o brightness -p 30
done

☝🏼 That would run as a loop endlessly in the background.

Isn't the correct Bash syntax this?

while true; do
    sunwait wait rise
    polychromatic-cli -o brightness -p 80
    sunwait wait set
    polychromatic-cli -o brightness -p 30
done

?
You can also substitute true with :

Yes, good catch, thanks! Yours is correct. I got confused with Python's syntax. I've edited my comment to fix up.
