Re: [AUCTeX] Problems with path?

[Markus Jäntti]

Hi -- I have now written a little documentation on this topic, included
below here. Note that for some reason, the variable TeX-master does not
get properly set from the %%% Local Variables in the foo.Rnw noweb file,
but if set manually to the correct value, things work as they should.

I am quite happy to modify the below text so that it is better suited
for the RefTeX documentation structure.

Regards,

Markus

Using RefTeX and AUCTeX with noweb files (in my example, those for the
Sweave package in the statistical program R) in emacs generally works
(see the Sweave FAQ,
http://www.ci.tuwien.ac.at/~leisch/Sweave/FAQ.html). However, a
multifile document with pieces consisting of noweb files may give you
some problems. In particular, RefTeX used to be unable to parse such
multifile documents correctly before the the included files were
created as .tex files, as opposed to the .nw or .Rnw files that are
actually edited.

Thus, suppose you have a document, master.tex, 

\documentsstyle{article}

\begin{document}

\include{foo}
\include{bar}

\end{document}

foo.Rnw and bar.Rnw are the Sweave files. Parsing master.tex *before*
the foo.tex and bar.tex files have been generated is going to lead to
problems, as is parsing the whole document from within the buffer in
which you are editing foo.Rnw.
  
With the newest version of RefTeX, available at
http://staff.science.uva.nl/~dominik/Tools/reftex/, it is possible to
do this properly. This is what you should do:

- download the latest version of RefTeX from 
  http://staff.science.uva.nl/~dominik/Tools/reftex/
- install it in a directory where emacs will find it (the default
  works for me; verify the correct RefTeX gets loaded by issuing from
  within emacs M-x locate-library RET reftex)
- set the following variables (if you are using pure noweb, .nw
   instead of .Rnw below should do the trick).


;; for RefTeX
.(setq reftex-file-extensions  '(("tex" . (".Rnw" ".tex" ".ltx"))
                                                    ("bib" . (".bib"))))

(setq reftex-try-all-extensions t)
;; for AUCTeX

(setq TeX-file-extensions 
      '("Rnw" "tex" "ltx" "sty" "cls" "ltx" "texi" "texinfo"))

- now: while the above AUCTeX setting should work, it does not. You
  need to explicitly set TeX-master to whatever value you want it to
  be, in my example "master" bvy issuing the command

  M-x set-variable RET TeX-master RET "master"

  This *regardless* of what the "Local variables" say, such as:

  %%% Local Variables:
  %%% TeX-master: "master"
  %%% End: 

  I have been unable to get this to work otherwise, but with this
  addition it works as it should:

These instructions have been tested with 

- GNU Emacs 21.4.1 (i486-pc-linux-gnu, X toolkit, Xaw3d scroll bars)
 of 2005-10-03 on trouble, modified by Debian

- RefTeX: 4.31 (latest off the web site)

- AUCTeX: 11.82
