Vim: Set Color/Theme based off time of day

Question

I have one of those super glossy monitors, so during the day I can see my own reflection better than my code on Dark themes. So I thought it'd be great if I could have a simple if switch in my vimrc to set either a dark theme or a light theme based on the time of day.

Alas, I don't know enough about vimrc syntax and googling came up short.

Anyone wanna take a crack at this?

Answer 1

Something like the following should do the trick:

if strftime("%H") < 12   set background=light else   set background=dark endif 

Obviously you should choose the hour based on your needs

Answer 2

This is not strictly a Vim answer but you could try to install f.lux which adjusts your monitor colours to the time of the day.

Here is a demo. It has a warm yellowish glow during the day, and blueish one during the night.
