有没有办法在Emacs中重命名打开的文件?在我看的时候?类似于另存为,但原始文件应该删除。

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)))))))

为了完整起见,由于有些人访问此页面时可能认为他们将得到Emacs的“另存为”特性的答案,对于打开的文件,这是C-x C-w。

优秀的crux包具有crux-rename-file-and-buffer(以及许多其他有用的函数)。

Emacs 26.3(2020-04-03)具有重命名文件功能,可以使用M-x重命名文件来重命名当前文件或任何其他文件。

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)))))))

我最喜欢的是来自Magnars (emacs岩石屏幕录制的名声)。

与其他选项不同的是,您不必从头输入名称—您可以获得要修改的当前名称。

(defun rename-current-buffer-file ()
  "Renames current buffer and file it is visiting."
  (interactive)
  (let* ((name (buffer-name))
        (filename (buffer-file-name))
        (basename (file-name-nondirectory filename)))
    (if (not (and filename (file-exists-p filename)))
        (error "Buffer '%s' is not visiting a file!" name)
      (let ((new-name (read-file-name "New name: " (file-name-directory filename) basename nil basename)))
        (if (get-buffer new-name)
            (error "A buffer named '%s' already exists!" new-name)
          (rename-file filename new-name 1)
          (rename-buffer new-name)
          (set-visited-file-name new-name)
          (set-buffer-modified-p nil)
          (message "File '%s' successfully renamed to '%s'"
                   name (file-name-nondirectory new-name)))))))
