Question

我在Rolodex模式下使用Vim，因此活动窗口总是被扩展为占用尽可能多的空间，但是非活动窗口每个至少有7行空间（如Why can't vim process .vimrc when winheight option isn't set twice?中所示））。

.vimrc中的相关行：

set winheight=7
set winminheight=7
set winheight=999

这很好用，但有一个问题。如果我尝试使用:sp打开更多窗口，以便没有足够的空间为每个窗口提供7行，则Vim会输出以下错误：E36: Not enough room。我想要的是，如果没有足够的空间，Vim应该打开一个新窗口，只需要根据需要减少所有窗口的最小窗口高度，稍后如果任何窗口关闭，最小窗口高度应该会增加再次（使窗口最小尺寸再次增加到7）。换句话说：如何让Vim认为窗口最小高度是理想的，而不是严格的要求？

我也试过Golden Ratio，但在黄金比例中有2个问题：非活动窗口变得非常小，非活动窗口也有不相等的大小，一些非活动窗口可能有3行，有些只有1行

Answer 1

对于初始拆分，如果可能的话，我会使用try ... catch ... endtry块进行拆分，如果不可能则调整窗口高度。例如，这显示了该方法（但不够聪明，无法确定窗口的小小）：

command! Split call MakeRoomAndSplit()

function! MakeRoomAndSplit()
  try
    split
  catch /E36:/
    let &winheight=&winminheight
    set winminheight=2
    set winheight=999
    split
  endtry
endfun

为了让你的窗户高度恢复，我认为你可以在autocmds中做类似的事情来检测关闭的窗口并相应地调整高度。例如：

augroup WINHEIGHT
  au!
  autocmd WinEnter * if exists('t:numwindows') && t:numwindows > winnr('$') | call IncreaseWinSize() | endif
  autocmd WinEnter * let t:numwindows = winnr('$')
augroup END

function! IncreaseWinSize()
  let oldheight = &winminheight
  try
    set winheight=7
    set winminheight=7
    set winheight=999
  catch /E36:/
    let &winheight=oldheight
    let &winminheight=&winheight
    set winheight=999
  endtry
endfun

通过扩大Ben的答案，我得到了我想要的东西。这是我的解决方案：

修改：修正了使用foo打开文件:Split foo时的错误。

set winheight=7
set winminheight=7
set winheight=999
