available from http://www.gnu.org/software/auctex/ if your
installation is older than the one available from the web site.

If the bug is triggered by a specific (La)TeX file, you should try
to produce a minimal sample file showing the problem and include it
in your report.

Your report will be posted for the auctex package at the GNU bug

Opening circ.tex with xemacs leads to the following error:
----------------------------------------------------------------------
(1) (local-variables/warning) File local-variables error: Symbol's value as variable is void: file-local-variables-alist
----------------------------------------------------------------------
Grepping over the *.el files in auctex directory, it seems that the
function font-latex-after-hacking-local-variables in font-latex.el
triggers this error.  Probably suitable boundp test is necessary.

Argh, a bug I introduced shortly before the release. ;-)

Do you know if XEmacs has some similar feature, i.e., a way to check
which variables have been set using file (or directory) local variables?
For reference, `file-local-variables-alist' is

  ((LaTeX-verbatim-macros-with-braces-local "hugo")
   (fill-column . 120))

in a buffer containing

% Local Variables:
% fill-column: 120
% End:

that corresponds to a file in a directory with a .dir-locals.el
containing

((latex-mode . ((LaTeX-verbatim-macros-with-braces-local . ("hugo")))))

[I think XEmacs has no directory local variables, so we can probably
ignore that.]

Bye,
Tassilo

Hmm, now I'm looking at files.el of xemacs and unfortunately xemacs
doesn't seem to have such features.

If you want to check whether a variable was set locally in a
XEmacs-compatible way you can use:

    (local-variable-p 'variable-name (current-buffer))

This is what is done in style/biblatex.el ;-)

No, that won't help here.  I need to know where that local binding came
from.  The reason is `LaTeX-verbatim-environments-local' and friends are
always buffer-local.  Styles like minted or lstlistings add to those
lists to make font-latex aware of the fact that, e.g., clojurecode, is a
verbatim environment generated by minted and should be highlighted as
such.  When such a style is loaded, a font-lock refresh is triggered to
put that into effect.

However, a user might also have

% Local Variables:
% LaTeX-verbatim-environments-local: ("mycode")
% End:

and the new function added to `hack-local-variables-hook' will then also
trigger a font-lock refresh.

Well, maybe we could rely that `hack-local-variables-hook' is always
executed before styles are applied (when finding a TeX file or running
`TeX-normal-mode').  In that case, if any of these variables in question
do have a local non-nil binding, then we trigger a font-lock refresh.
So we might trigger it too often but I guess that's acceptable.

Ikumi, I'll implement that now.  Could you please check if it works as
expected in the coming days?

Tassilo

The second argument of `local-variable-p' is mandatory in XEmacs ;-)

Gosh, can you please clean up after me? I'm already in the bringing sick

If not, no problem, I'll fix it tomorrow.

Did you also check that the feature works?  That is, that the code
between | and | in

\mycode|(lambda () "wohoo")|

is highlighted as verbatim in a file with

%% Local Variables:
%% LaTeX-verbatim-macros-with-delims: ("mycode")
