emacs功能不起作用，但没有错误消息(emacs function won't work, yet there is no error message)

emacs功能不起作用，但没有错误消息(emacs function won't work, yet there is no error message)

这是我第一次尝试为Emacs创建一个函数。

我创建了这个简单的函数：

(defun open-init-file () "Opens the ~/.emacs.d/init.el file" (find-file user-init-file))

我把它放进去：

~/.emacs.d/init.el

然后我跑了“eval-buffer”。

我没有收到任何错误消息。 然而，我无法调用此功能。 如果我输入Mx并输入“open-init-file”，我被告知没有与该名称匹配的功能。

即使我把这个函数放在自己的缓冲区中，把光标放在最后，然后运行eval-last-sexp，这个函数仍然不会在Emacs中看到。

然而，如果我把它放在缓冲区中：

(find-file user-init-file)

如果我把光标放在这个结尾，然后运行eval-last-sexp，那么这就像我期望的那样工作。

我究竟做错了什么？

This is my first attempt at creating a function for Emacs.

I created this simple function:

(defun open-init-file () "Opens the ~/.emacs.d/init.el file" (find-file user-init-file))

I put it in:

~/.emacs.d/init.el

I then ran "eval-buffer".

I got no error message. And yet I can not call this function. If I type M-x and type "open-init-file" I am told that there is no function matching that name.

Even if I put this function in its own buffer, put the cursor at the end, and run eval-last-sexp, this function still is not see as existing in Emacs.

And yet, if I put this in a buffer:

(find-file user-init-file)

and if I put the cursor at the end of this and then run eval-last-sexp, then this works as I expect.

What am I doing wrong?

你应该制作和interactive功能（又名命令）

(defun open-init-file () "Opens the ~/.emacs.d/init.el file" (interactive) (find-file user-init-file))

You should make and interactive function (a.k.a. a command)

(defun open-init-file () "Opens the ~/.emacs.d/init.el file" (interactive) (find-file user-init-file))
