vim - 使不活动的拆分 Pane 变暗

Question

如果您熟悉 iTerm2 应用程序，您就会知道您可以像 vim 一样 Split View，并且不活动的 View 会“变暗”。

我通常在 vim 中使用三个垂直 Split View，例如，通过将背景颜色设置为较暗的色调来使不活动的 View 变暗会很好。

有没有办法做到这一点？

我想出了以下解决方案(使用'colorcolumn'并取消设置'cursorline'):

" Dim inactive windows using 'colorcolumn' setting
" This tends to slow down redrawing, but is very useful.
" Based on https://groups.google.com/d/msg/vim_use/IJU-Vk-QLJE/xz4hjPjCRBUJ
" XXX: this will only work with lines containing text (i.e. not '~')
function! s:DimInactiveWindows()
  for i in range(1, tabpagewinnr(tabpagenr(), '$'))
    let l:range = ""
    if i != winnr()
      if &wrap
        " HACK: when wrapping lines is enabled, we use the maximum number
        " of columns getting highlighted. This might get calculated by
        " looking for the longest visible line and using a multiple of
        " winwidth().
        let l:width=256 " max
      else
        let l:width=winwidth(i)
      endif
      let l:range = join(range(1, l:width), ',')
    endif
    call setwinvar(i, '&colorcolumn', l:range)
  endfor
endfunction
augroup DimInactiveWindows
  au!
  au WinEnter * call s:DimInactiveWindows()
  au WinEnter * set cursorline
  au WinLeave * set nocursorline
augroup END
