Remember to cover the basics, that is, what you expected to happen and
what in fact did happen.

Be sure to consult the FAQ section in the manual before submitting
a bug report. In addition check if the bug is reproducable with an
up-to-date version of AUCTeX. So please upgrade to the version
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 bug report will be posted to the AUCTeX bug reporting list.

When I find a document that includes "\usepackage{setspace}" I get the
error

To reproduce the error simply find a file containing

\documentclass{minimal}
\usepackage{setspace}
\begin{document}
\end{document}

preview-1.286; Foreground always black with XeLaTeX

Remember to cover the basics.  Including a minimal LaTeX example
file exhibiting the problem might help.

When TeX-engine set to xelatex, foreground color fixed to black.

Steps to reproduce:

1. Start emacs with -q (Confirmed with both Emacs 24 and 23)

2. M-x set-background-color to black and M-x set-foreground-color
   to white

3. Evaluate these AUCTeX loading configuration:

--8<---------------cut here---------------start------------->8---
(load "auctex.el" nil t t)
(load "preview-latex.el" nil t t)
(setq TeX-engine-alist
      '((xelatex "XeLaTeX" "xetex" "xelatex" "xelatex")))
(add-hook 'LaTeX-mode-hook
          '(lambda ()
             (setq TeX-engine 'xelatex)))
--8<---------------cut here---------------end--------------->8---

4. Find an arbitrary LaTeX document, and C-c C-p C-d.

Also found that if I don't set TeX-engine to xelatex as above,
color is fine.  And I tried using the builtin 'xetex engine,
foreground color is also black.

11.86; auctex/preview menu broken with emacs 23.3

auctex is much appreciated, however I've found an annoying bug with recent emacs.

I have a simple .emacs file with:

  (setq debug-on-error t)
  (load "auctex.el" nil t t)
  ;(setq TeX-auto-save t)
  ;(setq TeX-parse-self t)
  ;(setq-default TeX-master nil)
  (load "preview-latex.el" nil t t)

Then

1. start emacs on any .tex file
    note the LaTeX pull-down menu works fine
2. load some other program file in another window, e.g.
    ^x 5 f file.m
    now the LaTeX pull-down menu is not functional -- still there, but
    nothing in it. The same thing happens to the Command pull-down menu,
    however the other menus (including Preview) are not affected.

This happens on linux, freebsd.

This does not happen with emacs 23.2.

The file do have to be opened in different windows to see the bug.

Rather than a matlab file.m (emacs things obj-c) file, a file.c also
has the same effect. In fact even opening another .tex file triggers
the problem in the original file, though the new one is ok.

2011-09-18; wrong-type-argument sequencep 1

Hi,

Evaluating (comment-padright "%" 0) in a LaTeX file triggers a
"wrong-type-argument sequencep 1". This only happens if AUCTeX is
loaded. Reproducing in a clean environment is trivial (at least in Emacs 24):

1) Create a ~/tmp/main.tex file with:
=======================
\documentclass{article}

\begin{document}

\end{document}
=======================

2) Create a ~/tmp/test.el file with:
=======================
(load "/usr/share/emacs/24.0.92/lisp/newcomment.el.gz")
(add-to-list 'load-path "~/.emacs.d/el-get/auctex")
(load "auctex.el" nil t t)
(find-file "~/tmp/main.tex")
(toggle-debug-on-error)
(message "%s" (comment-padright "%" 0))
=======================

3) launch emacs with:

$ emacs -Q --eval '(load "~/test.el")'

Some more information follows.

11.86; Vertical bars and fontification

Remember to cover the basics, that is, what you expected to happen and
what in fact did happen.

(System info below.) 

Apologies if it is a config error at my end, but I've done a fair share of searching, and I can't find anything.
The only thing I have out of the ordinary is (I think)

 '(LaTeX-babel-hyphen-after-hyphen nil)
 '(LaTeX-verbatim-environments (quote ("verbatim" "verbatim*" "vcode")))

In a nutshell,

\documentclass{article}

\begin{document}
\begin{tabular}{|c|c|}%|

\end{tabular}
\end{document}

I'm getting this fontified as if the vertical bars were delimiting verbatim text. If I leave off the %|, I get
the rest of the file fontified to Courier which quite counterproductive (or was, until I found the
workaround).

In my writings I use '<<' and '>>' for quotation marks in accordance with 
Russian typographic tradition. I noticed that font locking fails to parse 
things correctly everithing after the enclosing '>>' inclusive. Please tell me 
how to fix this.

11.86; Preview background darker than frame background

My preview images appear darker than they should be.  Example:

--8<---------------cut here---------------start------------->8---
\documentclass{article}
\begin{document}
\begin{displaymath}
  a^2 + b^2 = c^2
\end{displaymath} 
\end{document}
--8<---------------cut here---------------end--------------->8---

C-c C-p C-d gives the result: http://tinypic.com/r/2r5g8rk/7

I am using color-theme.el Version: 6.6.0 and I get similar results with
other themes that have non-white backgrounds.  I don't get this behavior
with a white background.

11.86; menu function undocumented

I did C-h k, then selected the "Use XeTeX Engine" menu item.
Rather than getting a link to the source code, a meaningful command name, and some documentation, the
self-documenting editor produced the output below.

Presumably, the menu is automatically generated, and documentation of the commands is ignored / not
passed into the menu bar map.

===
<menu-bar> <Command> <TeXing Options> <Use XeTeX engine> runs the
command menu-function-67, which is an interactive Lisp function.

(menu-function-67)

Not documented.
