当我输入`：q`或`：qa`时,如何让gvim主窗口不退出？

相反,我希望它关闭文件并打开默认的无名称缓冲区.我有时不小心关闭了最后一个文件,我必须重启g vim并cd到正确的目录.

把它放在$MYVIMRC中

function! NumberOfWindows()
  let i = 1
  while winbufnr(i) != -1
  let i = i+1
  endwhile
  return i - 1
endfunction


function! DonotQuitLastwindow()
  if NumberOfWindows() != 1
    let v:errmsg = ""
    silent! quit
    if v:errmsg != ""
        "echohl ErrorMsg | echomsg v:errmsg | echohl NONE
        "echoerr v:errmsg
        echohl ErrorMsg | echo v:errmsg | echohl NONE
    endif
  else
     echohl Error | echo "Can't quit the last window..." | echohl None
  endif
endfunction

if has("gui_running")
    cnoreabbrev <expr> q getcmdtype() == ":" && getcmdline() == 'q' ? 'call DonotQuitLastwindow()' : 'q'
    cnoreabbrev <expr> qa getcmdtype() == ":" && getcmdline() == 'qa' ? 'call DonotQuitLastwindow()' : 'qa'
endif
