在"保存文件"之后,每个都代表什么？提示:(y,n,!,.,q,Cr,d或Ch)

Question

这个问题非常明显.当我关闭emacs并且一些更改未保存时,我被问到是否要保存文件并给出这个选项列表.我假设"y"和"n"是"是"和"否",但其他选项是什么？

Answer 1

输入?,你会得到一个缓冲显示:

Type SPC or `y' to save the current buffer;
DEL or `n' to skip the current buffer;
RET or `q' to give up on the save (skip all remaining buffers);
C-g to quit (cancel the whole command);
! to save all remaining buffers;
C-r to view this buffer;
d to view changes in this buffer;
or . (period) to save the current buffer and exit.

如果要添加/更改save-some-buffers函数期间发生的操作,则可以修改变量save-some-buffers-action-alist.也许如果你想添加一个绑定来保存更改并通过密钥杀死缓冲区k.你可以这样做:

(add-to-list 'save-some-buffers-action-alist
             `(?k ,(lambda (buf) (save-buffer buf) (kill-buffer buf))
                  ,(purecopy "save changes and kill the buffer")))

如果您查看文档save-some-buffers,它将指导您save-some-buffers-action-alist- 进一步指导您map-y-or-n-p- 实际上有关于该变量格式的文档.
