emacs lisp，如何获得缓冲区主要模式? [英] emacs lisp, how to get buffer major mode?

问题描述

我尝试在 Google 上搜索并查看手册，但仍然找不到如何获取缓冲区对象的主要模式.你能帮我举个例子或参考.谢谢

I have tried to search Google and look in the manual, but still cannot find how to get major mode of a buffer object. Can you help me with an example or a reference. Thanks

我能找到的唯一解决方案是在更改缓冲区然后更改回原始缓冲区后查询主要模式.有没有更好的方法?

only solution I could find was to query major-mode after changing the buffer and then changing back to original buffer. Is there a better way to do it?

推荐答案

有什么问题吗?

(defun buffer-mode (buffer-or-string)
  "Returns the major mode associated with a buffer."
  (with-current-buffer buffer-or-string
     major-mode))

with-current-buffer 将在返回时恢复缓冲区.

with-current-buffer will restore your buffer when it returns.
