emacs lisp, how to get buffer major mode?

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

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?

Solution

  • Is there a problem with that?

    (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 will restore your buffer when it returns.
