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
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。
其他回答
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。
它可以通过复制来实现。在文件上按Shift +c, emacs将要求您为路径指定一个名称,其中包括文件名,因此只需提供新名称,然后输入…当然,你必须删除前一个。
基于magnars版本,我修改如下,修复了INIT文件名部分:
(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)))))))
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)
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)))))))
