vim - 编辑新文件时自动保存当前缓冲区

Question

我对当前缓冲区进行了一些更改，我希望 vim 在我要使用以下命令编辑新文件时自动保存当前缓冲区:

:e another_file_which_is_not_a_buffer_in_vim_yet

我在 .vimrc 中添加了以下行文件，但它没有用。

autocmd BufLeave * update

Vim 仍然提示我 No write since last change ， 为什么？我怎样才能让它工作？顺便说一句，我只想保存当前缓冲区而不是所有缓冲区，因为保存所有缓冲区似乎会弄乱缓冲区的顺序，这会在我运行 :bp时带来麻烦。或 :bn .

Vim 有一个选项可以保存，其中包括 :edit除了什么触发autowrite :

set autowriteall

相关手册摘录:

autowrite :

'autowrite' 'aw'  boolean (default off)
                  global
  Write the contents of the file, if it has been modified, on each
  :next, :rewind, :last, :first, :previous, :stop, :suspend, :tag, :!,
  :make, CTRL-] and CTRL-^ command; and when a :buffer, CTRL-O, CTRL-I,
  '{A-Z0-9}, or `{A-Z0-9} command takes one to another file.
  Note that for some commands the 'autowrite' option is not used, see
  'autowriteall' for that.

和 autowriteall :

'autowriteall' 'awa'  boolean (default off)
                      global
                      {not in Vi}
  Like 'autowrite', but also used for commands ":edit", ":enew", ":quit",
  ":qall", ":exit", ":xit", ":recover" and closing the Vim window.
  Setting this option also implies that Vim behaves like 'autowrite' has
  been set.
