Mediawiki export bugs and export to Doxygen

[Michal Sojka <sojka@os.inf.tu-dresden.de>]

Hi all,

I wanted to try the experimental Mediawiki exporter and it fails to
export documents with dot code blocks (as the one provided below). I
tried to fix that myself but my elisp and org-babel knowledge is not
sufficient for that. I used org-mode 7.7.

The error was: "file-name-extension: Wrong type argument: stringp, nil".
I tracked it down and it seems that it is caused by (nth 2 info) being
nil in org-babel-exp-do-export, whereas in org-babel-exp-src-block,
which calls org-babel-exp-do-export, the information about :file and
:cmdline is still present.

Another problem is that the Mediawiki export doesn't obey the
org-confirm-babel-evaluate variable - it always wants to confirm the
evaluation of code block.

I have also seen
http://thread.gmane.org/gmane.emacs.orgmode/40746/focus=40749 but this
seems to solve different thing. Does anybody have a suggestion how to
solve this.

Additionally, I'm thinking about writing org exporter to Doxygen syntax.
I wanted to based it on Mediawiki exporter but I'm not sure whether it
is a good idea since the Mediawiki exporter doesn't seem to be
maintained. Again, any suggestions are welcomed.

And finally, the example that fails to export to mediawiki:
--8<---------------cut here---------------start------------->8---
#+TITLE: Test

#+begin_src dot :file generic_proto.png :cmdline -Tpng
digraph com {
in -> out;
in -> call
}
#+end_src

# Local Variables:
# org-confirm-babel-evaluate: nil
# End:
--8<---------------cut here---------------end--------------->8---

Thanks,
-Michal
