[O] Can I wrap a Babel call inside a macro?

[Sebastien Vauban]

Hello,

I did the following test, not fully successfull:

--8<---------------cut here---------------start------------->8---
#+name: current-time
#+begin_src sh
echo "$(date '+%Y%m%d.%H%M')"
#+end_src

#+results: current-time
: 20140123.2339

Date/time:
#+CALL: current-time()

#+results:
: 20140123.2339

#+MACRO: ct #+CALL: current-time()

The current date and time is:
{{{ct}}}.
--8<---------------cut here---------------end--------------->8---

as the HTML export gives:

--8<---------------cut here---------------start------------->8---
    <div id="outline-container-sec-1" class="outline-2">
      <h2 id="sec-1"><span class="section-number-2">1</span> Tests</h2>

      <div class="outline-text-2" id="text-1">
        <div class="org-src-container">
          <pre class="src src-sh" id="current-time">
<span style="color: #006FE0;">echo</span> <span style=
"color: #036A07;">"$(date '+%Y%m%d.%H%M')"</span>
</pre>
        </div>

        <p>Date/time:</p>
        <pre class="example">
20140123.2338
</pre>

        <p>The current date and time is: #+CALL: current-time().</p>
      </div>                             ^^^^^^^^^^^^^^^^^^^^^^
    </div>
--8<---------------cut here---------------end--------------->8---

As macros are expanded _before_ Babel calls are executed, I'd think this
is possible, but I must miss something...

Best regards,
  Seb
