检查主要模式是否等于几个emacs中的一个

Question

我找到了一个片段来关闭所有的dired缓冲区,我想在日出指挥官中使用它:

(defun er/kill-all-dired-buffers()
      "Kill all dired buffers."
      (interactive)
      (save-excursion
        (let((count 0))
          (dolist(buffer (buffer-list))
            (set-buffer buffer)
            (when (equal major-mode 'sr-mode) 
              (or (equal major-mode 'dired-mode))
              (setq count (1+ count))
              (kill-buffer buffer)))
          (message "Killed %i dired buffer(s)." count ))))
(setq sr-quit-hook 'er/kill-all-dired-buffers)

问题是,我不能让sr-mode和dired-mode一起工作.如何检查"主模式是否为sr-mode或dired-mode"？

编辑:只是一个语法错误.应该

(when (or (equal major-mode 'dired-mode) (equal major-mode 'sr-mode))

不得不承认它不太直观.

规范的方式是(when (derived-mode-p 'sr-mode 'dired-mode) ...).
