Hi,
I have a document with many sections not yet written (i.e. heading
without content) and I would like them to be ignored in the exported
file. I know, I could manually tag these headings with :noexport:, but
what about a more automated approach?
Now, I tried this:
(defun ignore-empty-section (headline contents info)
(when contents
(org-e-latex-headline headline contents info)))
(add-to-list 'org-e-latex-translate-alist
'(headline . ignore-empty-section))
This does ALMOST what I want: it ignores sections that are completely
empty. But I also want to ignore sections that have only empty
subsections (and so on, recursively). For example:
* Chapter
** this subtree should be ignored
*** no content
*** no content
** this subtree should not be ignored
*** subsection
**** finally, content
something weird
*** subsection
Any ideas? I tried parsing the HEADLINE stuff (the first argument), but
it looks a bit intimidating.
It's not super important, because it's a draft obviously, but it would
be nice.
Thanks,
Florian

Sometimes I create documents - not drafts, but final deliverables - with
empty sections and plain headlines. This way I get emboldened text that
stands out without resorting to emphasis.
You are probably writing a Thesis. Oftentimes, I create documents that
aren't as formal as Thesis. They are plain one-to-one-s which need to
look good, that is all.

The global idea is correct, but I find that the implementation is too
low level. It also taints original e-latex back-end.
I suggest the following instead:
#+begin_src emacs-lisp
(defun ignore-empty-section (headline contents info)
(when (org-string-nw-p contents)
(org-export-with-backend 'e-latex headline contents info)))
(org-export-define-derived-backend my-draft-latex e-latex
:translate-alist ((headline . ignore-empty-section))
;; Optionally add a sub-menu entry in the latex menu.
:menu-entry (?l 99 ((?d "As a draft PDF file" my-draft-latex))))
(defun my-draft-latex (&optional async subtreep visible-only body-only ext-plist)
(interactive)
(let ((outfile (org-export-output-file-name ".tex" subtreep)))
(if async
(org-export-async-start
(lambda (f) (org-export-add-to-stack f 'e-latex))
`(expand-file-name
(org-e-latex-compile
(org-export-to-file
'my-draft-latex ,outfile ,subtreep ,visible-only ,body-only
',ext-plist))))
(org-e-latex-compile
(org-export-to-file
'my-draft-latex outfile subtreep visible-only body-only
ext-plist)))))
#+end_src
Note that if you don't want the hassle of creating a derived back-end,
you can also implement a function that will remove every section
containing only sections or nothing from the buffer, and add it to
`org-export-before-processing-hook' (or
`org-export-before-parsing-hook').

Thanks a lot! A derived backend seems like a good idea. Unfortunatly,
the function org-export-with-backend isn't in the latest
org-plus-contrib package (20121231). I'll try it then.

Well, I've switched to the git version. The version in
"org-plus-contrib" is a very one from the maint-branch, which kind of
defeats the purpose of the package, doesn't it? Anyway, your suggestion
now works perfectly, thanks again.
