[New Exporter] org-export-latex-after-initial-vars-hook

[Søren Mikkelsen]

Hello,

I have just upgraded to the Org 8.0. Nice work! :)

But I have a problem with the exporter:

I have modified by org-exporter to export latex-files with the xelatex 
compiler. The implementation uses the 
"org-export-latex-after-initial-vars-hook"-hook to reconfigure the 
default process, however, this hook seems to be deleted and I'm not able 
to find equivalent hook.

Cheers,
Søren

Isn't it sufficient to customize `org-latex-pdf-process' so it uses
xelatex?

I assume Søren is using a similar snippet [1] as I do which is very
convenient (credit goes to Bruno Tavernier). This approach lets you
specify a #+LATEX_CMD (think of xelatex, -shell-escape, etc.) on a per
file basis and allows LaTeX package 'injection'.

Is there a hook that is run before actual LaTeX export of a given
org-mode buffer in the new exporter engine?

To minimize risk of eye cancer (previous version was sent from gmail
web interface at work without plain text setting) here it goes again:

For reference:
I got it to work by adapting the snippet from Bruno Tavernier[1]:
#+begin_src emacs-lisp
(defun my-auto-tex-cmd (backend)
    "When exporting from .org with latex,
    automatically run latex, pdflatex, or xelatex as appropriate,
    using latexmk."
    (let ((texcmd))
      (setq texcmd "latexmk -pdf %f")
      (if (string-match "LATEX_CMD: pdflatex" (buffer-string))
          (setq texcmd "latexmk -pdflatex=pdflatex -pdf %f"))
      (if (string-match "LATEX_CMD: pdflatex-shell-escape" (buffer-string))
          (setq texcmd "latexmk -pdflatex=pdflatex --shell-escape -pdf %f"))
      (if (string-match "LATEX_CMD: xelatex" (buffer-string))
          (setq texcmd "latexmk -pdflatex=xelatex -pdf %f"))
      (setq org-latex-pdf-process (list texcmd))))
  (add-hook 'org-export-before-parsing-hook 'my-auto-tex-cmd)
#+end_src

One thing that tripped me up initially was the requirement for the function to 
accept exactly one argument (unused in this case).
