I stare way too long at the screen – I guess we all do. I have my monitor contrast and brightness turned down pretty low, and use software like f.lux to automatically adjust my computer screen.

Above all, I absolutely love Solarized. Everytime I switch to some other theme, I find myself coming back to Solarized.

Solarized comes in 2 flavours, light and dark. For those who have no idea what I’m talking about, here’s some eye candy:

Solarized Light

Solarized Dark

So here’s the thing. I was wondering if it is possible to automatically switch between Solarized (Dark|Light) based on the time of day.

During the day, I want it dark. At night, I want the light version.

Just put this little piece of awesomeness in your .vimrc:

let hour = strftime("%H")
if 6 <= hour && hour < 18
  set background=light
else
  set background=dark
endif

colorscheme solarized

So when it is between than 6 a.m. and 5 p.m (hour is an integer), Solarized Light is activated. Otherwise, Solarized Dark.

Hope you found this useful!
