下面是一个改编自史蒂夫的更健壮的版本。

;; Originally from stevey, adapted to support moving to a new directory.
(defun rename-file-and-buffer (new-name)
  "Renames both current buffer and file it's visiting to NEW-NAME."
  (interactive
   (progn
     (if (not (buffer-file-name))
         (error "Buffer '%s' is not visiting a file!" (buffer-name)))
     ;; Disable ido auto merge since it too frequently jumps back to the original
     ;; file name if you pause while typing. Reenable with C-z C-z in the prompt.
     (let ((ido-auto-merge-work-directories-length -1))
       (list (read-file-name (format "Rename %s to: " (file-name-nondirectory
                                                       (buffer-file-name))))))))
  (if (equal new-name "")
      (error "Aborted rename"))
  (setq new-name (if (file-directory-p new-name)
                     (expand-file-name (file-name-nondirectory
                                        (buffer-file-name))
                                       new-name)
                   (expand-file-name new-name)))
  ;; Only rename if the file was saved before. Update the
  ;; buffer name and visited file in all cases.
  (if (file-exists-p (buffer-file-name))
      (rename-file (buffer-file-name) new-name 1))
  (let ((was-modified (buffer-modified-p)))
    ;; This also renames the buffer, and works with uniquify
    (set-visited-file-name new-name)
    (if was-modified
        (save-buffer)
      ;; Clear buffer-modified flag caused by set-visited-file-name
      (set-buffer-modified-p nil)))

  (setq default-directory (file-name-directory new-name))

  (message "Renamed to %s." new-name))

这是另一个版本，它非常健壮，并且支持VC:

(defun rename-file-and-buffer ()
  "Rename the current buffer and file it is visiting."
  (interactive)
  (let ((filename (buffer-file-name)))
    (if (not (and filename (file-exists-p filename)))
        (message "Buffer is not visiting a file!")
      (let ((new-name (read-file-name "New name: " filename)))
        (cond
         ((vc-backend filename) (vc-rename-file filename new-name))
         (t
          (rename-file filename new-name t)
          (set-visited-file-name new-name t t)))))))

如果您正在使用Spacemacs，那么您可以免费获得这种行为，因为它附带了一个重命名-current-buffer-file的实现(基于magnars)，默认情况下绑定到src -f- r。

试试Steve Yegge的.emacs中的这个函数:

;; source: http://steve.yegge.googlepages.com/my-dot-emacs-file
(defun rename-file-and-buffer (new-name)
  "Renames both current buffer and file it's visiting to NEW-NAME."
  (interactive "sNew name: ")
  (let ((name (buffer-name))
        (filename (buffer-file-name)))
    (if (not filename)
        (message "Buffer '%s' is not visiting a file!" name)
      (if (get-buffer new-name)
          (message "A buffer named '%s' already exists!" new-name)
        (progn
          (rename-file filename new-name 1)
          (rename-buffer new-name)
          (set-visited-file-name new-name)
          (set-buffer-modified-p nil))))))

看一下那个页面，那里有另一个非常有用的相关函数，叫做“move-buffer-file”。

是的，使用dired模式，你可以:

c - xd打开干燥 RET选择当前文件的目录 C-x C-j (Dired -跳转到当前文件的名称，在Dired中) R来重命名文件(或dired-do-rename)。 Q返回(重命名的)文件缓冲区

重命名相当于shell mv，但它也会更新任何打开的缓冲区，与mv不同的是，它不会改变文件系统中文件的访问和修改时间。

我没有发现任何建议的解决方案足以满足我的需求(缓冲区选择，覆盖确认，快速响应，实际工作等)，以下是我正在使用的:

(defun rename-buffer-and-file (buffer newname)
  (interactive "bRename buffer and its visiting file: \nFNew name: ")
  (let ((oldname (buffer-file-name)))
    (if (not oldname)
        (message "Buffer '%s' is not visiting a file" buffer)
      (if (file-exists-p newname)
          (if (file-directory-p newname)
              ;; Signal an error if the user specified the name of an
              ;; existing directory.
              (error "%s is a directory" newname)
            (unless (y-or-n-p (format-message
                               "File `%s' exists; overwrite? "
                               newname))
              (error "Canceled"))))
      ;; Rename buffer and its visiting file
      (set-visited-file-name newname)
      ;; Delete old file
      (delete-file oldname)
      (save-buffer))))

绑定到C-x - C-r以便于

(global-set-key (kbd "C-x C-r") 'rename-buffer-and-file)
