Hi,

I have several questions about macro replacement usage.

1. I saw people using {{{n}}} macros, which looks very useful, but I could = not find it in current documentation about macro replacement (http://or= gmode.org/manual/Macro-replacement.html). Is this only available i= n developmental version?

Yes, I'm pretty sure this has not bee= n merged yet

2. I was wondering if it is possible use macro expansion for=C2=A0:EXPORT_F= ILE_NAME: property of a subtree?
Since macros = can be set to expand to arbitrary elisp, I would think this *should* be pos= sible.=C2=A0 I forget the syntax but something like:

#+MACRO: efn (eval (get-export-file-name))

= #+BEGIN_SRC emacs-lisp
(defun get-export-file-name ()
= =C2=A0(org-element-property :export-file-name (org-element--current-element= ) ))
#+END_SRC

* some heading
<= div>:PROPERTIES
:EXPORT_FILE_NAME: test-me
:END:

will get you somewhat close.=C2=A0 I don't under= stand the org-element api very well though and it generally takes me a few = tries to get this sort of thing right.

3. Is it possible to create a file link which uses macro? I would like to c= reate a link to the exported pdf file dynamically.=C2=A0For example, if the value of=C2=A0:EXPOR= T_FILE_NAME: is exported, how would I create a link which automatically link to exported.pdf?

I don't think a macro will do this for you since, if I underst= and correctly, macros are not aware of the export target.=C2=A0 So probably= you would need some other mechanism to od this.

Any help would be greatly appreciated. Thank you!
Joon
