VIM Toggle Background Scheme

Written by Ho Man May 20, 2014 less than a minute read

Have you ever wanted BOTH the dark and the light background schemes in VIM? Perhaps in the day, you feel that you can concentrate better with a light background and at night, the dark. I did! So I bound one of my Fn keys to do just that.

This works well for color schemes that offer both dark and light versions, for example Solarized.

let g:scheme_bg = "dark"

function! ToggleDark()
  if g:scheme_bg == "dark"
    set background=light
    let g:scheme_bg = "light"
  else
    set background=dark
    let g:scheme_bg = "dark"
  endif
endfunction

map <F3> :call ToggleDark()<CR>
