How to include a very complicated latex head

How to include a very complicated latex head

[FengShu]

I want to set the latex-head for latex exporting, I use 
*org-export-latex-append-header*,but it seem not used by
*org-preview-latex-fragment* . is there any other way?
simple way?  

#+begin_latex
\ifxetex    % xelatex
  \usepackage[xetex]{hyperref}
\else
  \ifpdf    % pdflatex
    \usepackage[pdftex,unicode]{hyperref}
  \else     % dvipdfmx or dvips
    \usepackage[dvipdfmx,unicode]{hyperref}
    %\usepackage[ps2pdf,unicode]{hyperref}
  \fi
\fi

\ifxetex\else\ifpdf\else
  % pdftex 3.1415926-1.40.10-2.2 has trouble with it
  \InputIfFileExists{zhwinfonts.tex}{}{}
\fi\fi
#+end_latex

#+begin_src emacs-lisp
(setq  org-export-latex-append-header
       "
\\ifxetex    % xelatex
  \\usepackage[hyperref,UTF8,nofonts]{ctex}
  \\setCJKmainfont[ItalicFont={AR PL UKai CN}]{AR PL UMing CN}% 文鼎宋体和楷书
  \\setCJKsansfont{WenQuanYi Zen Hei}% 文泉驿的黑体
  \\setCJKmonofont{WenQuanYi Zen Hei}
  \\usepackage[xetex]{hyperref}
\\else
  \\ifpdf    % pdflatex
    \\usepackage[pdftex,unicode]{hyperref}
  \\else     % dvipdfmx or dvips
    \\usepackage[dvipdfmx,unicode]{hyperref}
    %\\usepackage[ps2pdf,unicode]{hyperref}
  \\fi
\\fi

\\ifxetex\\else\\ifpdf\\else
  % pdftex 3.1415926-1.40.10-2.2 has trouble with it

I'm using this (I don't know if it's simpler or not).

Hope this helps,

You are right - org-preview-latex-fragment is independent of the latex
exporter.  The preview latex header is constructed (in
org.el:org-create-formula-image) like this:


,----
|     (with-temp-file texfile
|       (insert (org-splice-latex-header
| 	       org-format-latex-header
| 	       org-export-latex-default-packages-alist
| 	       org-export-latex-packages-alist t
| 	       org-format-latex-header-extra))
|       (insert "\n\\begin{document}\n" string "\n\\end{document}\n")
|       ...
`----

so you might want to experiment with the variable
org-format-latex-header-extra (and maybe some of the others as well).

Certainly far from simple: but if your trial-and-error succeed, then you
might be able to propose a simpler mechanism.  Let us know.
