Include lengthy LaTeX in export preamble

Include lengthy LaTeX in export preamble

I have a lengthy command customization that I want to include in LaTeX
export. Since it must appear in the preamble,
#+BEGIN_LATEX
...
#+END_LATEX

didn't work. I had to prepend
#+LATEX_HEADER:
to each line in order to achieve my result.

I found C-h v org-format-latex-header RET:

"The document header used for processing LaTeX fragments..."

But it seems that when the docstring says "fragments," it is not referring
to exporting.

Are there any customizations to do the same during export?

Thanks,
Jake

Hi Jacob,

#+LATEX_HEADER: does work on export (when else would it work?)

I think I recall a space between the ":" and the LaTeX command is
needed. Do you have one?

For more ideas on how to have lengthy custom headers, see thread here:
https://lists.gnu.org/archive/html/emacs-orgmode/2014-06/msg00734.html
and links therein. There are three general approaches:

1) Make a custom class file and include that, either in your init file
or in the Org file.

2) From Aaron Ecay, put your header in a #+BEGIN_SRC latex section, and
then run a bit of lisp to export that section, and then include the
exported file in a #+LATEX_HEADER: \include{preamble}. This is the
approach I use.

,----
| #+begin_src emacs-lisp
|   (org-babel-goto-named-src-block "preamble")
|   (org-babel-tangle)
| #+end_src
| 
| #+name: preamble
| #+begin_src latex :tangle preamble.tex
|   % code goes here
| #+end_src
`----

3) Implement a patch or pester developers to create a third simpler
solution.

Good luck,

  -k.

This looks handy. Thanks!

My elisp ability is minimal, but if someone can point me towards where I
would look to try to create an export analogue to org-format-latex-header,
I would at least take a look and try to come up with a patch.

Thanks,
Jake
