检测VIM中是否存在quickfix缓冲区

Question

简单的问题(我希望).这让我疯了.我正在尝试在我的vimrc中创建一个简单的脚本来映射:

<Leader>e

打开quickfix窗口.如果当前打开,我还希望关键组合关闭quickfix窗口.问题是,bufexists命令似乎跳过了quickfix缓冲区.你能否就如何检测是否已经打开quickfix窗口给我一些建议？

该:cwindow命令可能是您正在寻找的.从帮助:

                            *:cw* *:cwindow*
:cw[indow] [height] Open the quickfix window when there are recognized
                    errors.  If the window is already open and there are
                    no recognized errors, close the window.

但是,如果您想关闭quickfix窗口,即使仍有错误,请查看此Vim提示,它提供以下代码段:

command -bang -nargs=? QFix call QFixToggle(<bang>0)
function! QFixToggle(forced)
  if exists("g:qfix_win") && a:forced == 0
    cclose
    unlet g:qfix_win
  else
    copen 10
    let g:qfix_win = bufnr("$")
  endif
endfunction
