The main problem is that the latex->dvi invocation is hard-wired in
org-create-formula-image-with-dvipng and in addition, when the latex
file is created, the value of org-latex-packages-alist is spliced in.
That in itself is fine, except in the case when (for normal latex
processing) I choose minted for code prettification. Following the
docstring of or-export-latex-listings, I set:
(setq org-export-latex-listings 'minted)
(add-to-list 'org-latex-packages-alist '("" "minted"))
in which case, I end up with a \usepackage{minted} in the preview
latex file. But minted requires that latex be invoked with
--shell-escape, which cannot be done because the latex->dvi invocation
is hardwired.
A customizable variable to hold such options could be used, but there
might be cleaner ways. For now, I've used the even dirtier approach of
hard-wiring the option into the latex->dvi call in the above function:
--8<---------------cut here---------------start------------->8---
...
(call-process "latex" nil nil nil "--shell-escape" texfile))
...
--8<---------------cut here---------------end--------------->8---
If a customizable variable is added, then the docstring for
org-export-latex-listings will need to be modified to mention it.
And finally, the same docstring also refers to org-latex.el and
org-latex-to-pdf-process, rather than using the 8.x names.
If you want to experiment, here is a small file:
--8<---------------cut here---------------start------------->8---
* Euler
\[
e^{i\pi} = -1
\]
--8<---------------cut here---------------end--------------->8---
Hit C-c C-x C-l for the preview, C-c C-c to go back.
