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

FWIW, I couldn't reproduce your problem in either maint or master
branch.

BTW, the period seems dubious here.

What do you mean? That, because the macro will ultimately make a Babel
call, it can't be inserted inline in some text, right?
I'd have to write:
>>> The current date and time is:
>>> {{{ct}}}
>>> .
Is this what you mean?
Best regards,
Seb
PS- I'll have to look why it works for you and not for me...

Correct. After macro expansion, this will become:
#+CALL: current-time().
which isn't valid Babel syntax, AFAIK.

OK. New tests confirm that, definitively.
So, when you said it worked for you, it wasn't with the exact same ECM,
then. Case closed. Thanks!
Best regards,
Seb
