[AUCTeX] problem with TeX-command-extra-options

[Alfredo Buttari]

Hi,
I have a large .tex file with the following footer:

%%% Local Variables:
%%% mode: latex
%%% TeX-master: t
%%% TeX-engine: xetex
%%% TeX-command-extra-options: "-shell-escape --enable-write18 --synctex=1"
%%% End:

When I open it I am asked whether I want to accept the potentially unsafe
value for the TeX-command-extra-options. In this message the potentially
unsafe value corresponds to what I have in the footer, i.e., "-shell-escape
--enable-write18 --synctex=1". I hit yes and the file is opened. However,
if I ask emacs to describe variable TeX-command-extra-options (with C-h
C-v) I get this:

TeX-command-extra-options is a variable defined in `tex.el'.
Its value is "--synctex=1"
Original value was ""
Local in buffer hdr.tex; global value is ""

Automatically becomes buffer-local when set.

Documentation:
String with the extra options to be given to the TeX processor.

You can customize this variable.



It seems that the value of this variable is overwritten once again in some
other place. Note that this does not happen if I create a simple file
containing only (exactly the same footer):


\documentclass{article}

\begin{document}

\end{document}

%%% Local Variables:
%%% mode: latex
%%% TeX-master: t
%%% TeX-engine: xetex
%%% TeX-command-extra-options: "-shell-escape --enable-write18 --synctex=1"
%%% End:


Could you please help me figure out what's happening?

regards,
Alfredo

If you have it, try deleting the auto/hdr.el file, automatically
generated by AUCTeX when parsing the document. The value of
`TeX-command-extra-options' is stored there, in order to make it
available to all files part of the same document, but if you change
the value of that variable you can incur this nuisance.

In addition, note that you can enable `TeX-source-correlate-mode' in
order to get forward/inverse search, without setting `--synctex=1' in
in `TeX-command-extra-options'.

Bye,
Mosè

Ciao MosÚ,
thanks a lot for the quick reply. This indeed fixed the problem. And thanks
also for the TeX-source-correlate-mode tip, this is much cleaner than
adding the --synctex option.

Regards,
Alfredo
