如何打开backup-each-save.el在dired中由dired-jump创建的最新备份文件，例如 1. Get the backup directory of the file connected to current opening file buffer. 2. Open the backup directory. 3. In the dired buffer, go to end of the buffer. 4. Search backward for the basename of opening file. ？

Answer 1

这是算法及其代码。

算法：

(defun backup-each-save-dired-jump ()
  (interactive)
  (let* (
         (filename (buffer-file-name))
         (containing-dir (file-name-directory filename))
         (basename (file-name-nondirectory filename))
         (backup-container
          (format "%s/%s"
                  backup-each-save-mirror-location
                  containing-dir))
         )
    (when (file-exists-p backup-container)
      (find-file backup-container)
      (goto-char (point-max))
      (search-backward basename)
      )))
