A simple solution is to define a macro that calls your function then use the good ol' <code>apply-macro-to-region-lines</code>.

Apart from that, I think that you could write a loop in a few lines of elisp that does exactly what you ask for. If you would like to be fancy, you can even prompt the user for the name of the function. I think this is a good exercise for elisp, I can help you with some pointers if you feel like you would like to try it yourself.

blocks|key|5047816|text|我同意@Lindydancer的回答，我还想补充说，也许有一种更容易的方法来实现你的目标。例如，内置函数delete-matching-lines。:-)|type|unstyled|depth|inlineStyleRanges|offset|length|style|CODE|entityRanges|data|5047817|entityMap^0|1G|L|0^^$0|@$1|2|3|4|5|6|7|H|8|@$9|I|A|J|B|C]]|D|@]|E|$]]|$1|F|3|-4|5|6|7|K|8|@]|D|@]|E|$]]]|G|$]]

I agree with @Lindydancer's answer, and I'd also add that there might be an easier way to accomplish your goal. e.g. the built-in function <code>delete-matching-lines</code>. :-)

blocks|key|3262399|text|您可以随时将源代码复制到apply-macro-to-region-lines，并调整它以调用传入的函数，从而生成您自己的版本。|type|unstyled|depth|inlineStyleRanges|offset|length|style|CODE|entityRanges|data|3262400|entityMap^0|C|R|0^^$0|@$1|2|3|4|5|6|7|H|8|@$9|I|A|J|B|C]]|D|@]|E|$]]|$1|F|3|-4|5|6|7|K|8|@]|D|@]|E|$]]]|G|$]]

You could always copy the source to <code>apply-macro-to-region-lines</code> and tweak it to call a passed in function, and thus make your own version.

The following function should do what you want:

<pre><code>(defun apply-function-to-region-lines (fn)
 (interactive "aFunction to apply to lines in region: ")
 (save-excursion
 (goto-char (region-end))
 (let ((end-marker (copy-marker (point-marker)))
 next-line-marker)
 (goto-char (region-beginning))
 (if (not (bolp))
 (forward-line 1))
 (setq next-line-marker (point-marker))
 (while (&lt; next-line-marker end-marker)
 (let ((start nil)
 (end nil))
 (goto-char next-line-marker)
 (save-excursion
 (setq start (point))
 (forward-line 1)
 (set-marker next-line-marker (point))
 (setq end (point)))
 (save-excursion
 (let ((mark-active nil))
 (narrow-to-region start end)
 (funcall fn)
 (widen)))))
 (set-marker end-marker nil)
 (set-marker next-line-marker nil))))
</code></pre>

So, if you have the following function that you want to apply against lines in a buffer:

<pre><code>(defun test()
 (insert "&gt; "))
</code></pre>

And, if your buffer contains the following contents:

<pre><code>Line 1: blah, blah
Line 2: blah, blah
Line 3: blah, blah
Line 4: blah, blah
</code></pre>

If you select a region enclosing just lines 2 &amp; 3, enter "M-x apply-function-to-region-lines", and enter "test" as the function name when prompted, you will get the following result in your buffer:

<pre><code>Line 1: blah, blah
&gt; Line 2: blah, blah
&gt; Line 3: blah, blah
Line 4: blah, blah
</code></pre>

A lot of my work involves searching and deleting unnecessary lines of code. So I create a macro, and then select all lines <code>(C-x h)</code> and then run the command <code>(apply-macro-to-region-lines)</code>. I managed to save that command and placed it in my <code>.emacs</code> file; I called it <code>cut_it_now</code>. But now my function is not a macro anymore, so I can't use the <code>(apply-macro-to-region-lines)</code> function anymore. 
Do you know if there is <code>(apply-function-to-region-lines)</code> implemented somewhere?

Many thanks,

D

Is there a apply-function-to-region-lines in emacs?

我的很多工作包括搜索和删除不必要的代码行。所以我创建了一个宏，然后选择所有行(C-x h)，然后运行命令(apply-macro-to-region-lines)。我设法保存了该命令，并将其放在我的.emacs文件中；我将其命名为cut_it_now。但是现在我的函数不再是宏，所以我不能再使用(apply-macro-...
