Hello, I’d like to being able to preview chemfig, like lines beginning
with \chemfig{.
But (a) they’re not detected as LaTeX fragments by the previewer (and it
seems only some matchers are accepted by default, I can’t say, for
instance, “^{\\[a-zA-Z]*[a-zA-Z0-9 ].*}$”), and (b) when previewing I
don’t see any way to include packages, like “\usepackage{chemfig}”, so
that even “\begin{flushleft}<\n>\chemfig{O=O}<\n>\end{flushleft}”, for
instance, doesn’t work.
Is there any way to do this? Otherwise, how could I fix it? Which part
of org-mode to hack? Could this be improved for next release?

Have you tried
#+LATEX_HEADER: \usepackage{chemfig}

Yes. I think it doesn’t influence the preview system.

It should. Perhaps your Org is outdated.

Ok, I tested again, and found that actually any preview (even without
chemfig) completely stops working when I add
« #+LATEX_HEADER:\usepackage{chemfig} », even pure maths. I just get
little shrinked transparent void rectangles.
I’m on Debian Testing (Jessy) and hence use Org version 7.9.3f (GNU
Emacs 24.3).

To debug check you *Message* buffer. You might see something like
LaTeX errors in `*/tmp/orgtex1687lRq output*'. Use C-c ` to display.
Check the file, compile it, and check that everything works. Compile it
to dvi and try to run dvipng on the file.
For me, dvipng is unhappy about chemfig since it seems to contain PS
elements. If I do
(setq org-latex-create-formula-image-program 'imagemagick)
everything works since it's converted to pdf rather than dvi.
(org-version) => "8.3beta".

You might get better results with a recent version of Org. If you
upgrade to Emacs 24.4 you should get Org 8.2.10, I think.

Nothing in *messages*.

And suddenly, after some trials, everything worked… :D thank you!

Myeah, mixing distribution releases is not always a good idea, but I
think with Emacs it’s fine, and I want so much 24.4 features I’ll
probably do it in little time.
