Hi List,
in ox.el I find this function for getting the (optional) alternative title of
a headline:
#+begin_src emacs-lisp
(defun org-export-get-alt-title (headline info)
"Return alternative title for HEADLINE, as a secondary string.
INFO is a plist used as a communication channel. If no optional
title is defined, fall-back to the regular title."
(or (org-element-property :alt-title headline)
(org-element-property :title headline)))
#+end_src
I'm not so sure that it is a good idea to fallback to the regular title in
case :alt-title is nil, because when extracting both, title and alt-title,
from a headline, there is a almost always a duplication (the regular title
string is received two times, via the get-title and get-alt-title functions)
because :alt-title isn't really set very often.
Wouldn't it make more sense to just return nil when :alt-title is nil? If the
application code needs a title string anyway, it can always fall-back to a
call to the get-title function.
