blocks|key|1583940|text|如果您希望Emacs将所有新文件视为已修改文件，则可以像这样自动化解决方案：|type|unstyled|depth|inlineStyleRanges|entityRanges|data|1583941|(add-hook+'find-file-hooks+'assume-new-is-modified)

If you want Emacs to treat all new files as modified, you can automate the solution like this:

<pre class="lang-el prettyprint-override"><code>(add-hook 'find-file-hooks 'assume-new-is-modified)
(defun assume-new-is-modified ()
 (when (not (file-exists-p (buffer-file-name)))

I've modified answer from MrBones and created custom function with keybinding:

<pre><code>; create empty __init__.py at the place

 (shell-command "touch __init__.py")

Here's an adaptation of <code>dired-create-directory</code>. It works the same way, so as well as a plain filename, you can also specify new parent directories (to be created under the current directory) for the file (e.g. <code>foo/bar/filename</code>).

<pre class="lang-el prettyprint-override"><code>(eval-after-load 'dired
 '(progn
 (define-key dired-mode-map (kbd "C-c n") 'my-dired-create-file)
 (defun my-dired-create-file (file)
 "Create a file called FILE.
If FILE already exists, signal an error."
 (interactive
 (list (read-file-name "Create file: " (dired-current-directory))))
 (let* ((expanded (expand-file-name file))
 (try expanded)
 (dir (directory-file-name (file-name-directory expanded)))
 new)
 (if (file-exists-p expanded)
 (error "Cannot create file %s: file exists" expanded))
 ;; Find the topmost nonexistent parent dir (variable `new')
 (while (and try (not (file-exists-p try)) (not (equal new try)))
 (setq new try
 try (directory-file-name (file-name-directory try))))
 (when (not (file-exists-p dir))
 (make-directory dir t))
 (write-region "" nil expanded t)
 (when new
 (dired-add-file new)

Programatically and without any dependency on <code>touch</code>, it's quite easy:

 (with-temp-buffer
 (write-file filename)))

After this thread, Emacs has added two new commands:

<ol>
<li>make-empty-file</li>
<li>dired-create-empty-file</li>
</ol>

These commands will be available in the emacs 27.1 release.

How can I create an empty file from emacs, ideally from within a dired buffer?

For example, I've just opened a Python module in dired mode, created a new directory, opened that in dired, and now need to add an empty <code>__init__.py</code> file in the directory.

If I use <code>C-x C-f __init__.py RET C-x C-s</code> then emacs doesn't create the file because no changes have been made to it. I would have to type in the file, save it, delete my typing and then save it again for that to work.

Thanks
