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。
当前回答
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。

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)))))))
