[AUCTeX] XEmacs and ZUCTeX Problems

[Ernst Joachim Weniger]

                                                   21 November 2005

Dear Mike,

I discovered another problem with XEmacs in connection with AUCTeX under
Suse 9.3, which I will describe below.

A detailed system info for my XEmacs instalation follows at the end of this
email. 

The current state of AUCTeX on my PC is as follows:

> Emacs  : XEmacs 21.5  (beta22) "cucumber" (+CVS-20050913) [Lucid] 
> (i386-suse-lin
> ux, Mule) of Tue Sep 20 2005 on barry
> Package: AUCTeX CVS-1.13 (2005-02-11)
> 
> current state:
> ==============
> (setq
>  window-system 'x
>  LaTeX-version "2e"
>  TeX-style-path '("style/" "auto/" "~/TeX/style/" "~/TeX/auto/"
>                   "/usr/share/xemacs/xemacs-packages/etc/auctex/style/"
>                   "/usr/share/xemacs/xemacs-packages/etc/auctex/auto/")
>  TeX-auto-save nil
>  TeX-parse-self nil
>  TeX-master nil
>  )

When I use within AUCTeX the commend ^c^q^e to format an environment such
as \begin{align} ... \end{align}, strange things happen.

Let us assume that I have the following environment in my LaTeX sourde code:

  \begin{subequations}
  \label{EuMaclau}
  \begin{align}
  % \label{}
  \sum_{\nu=M}^{N} \, g (\nu) & \; = \; \int_{M}^{N} \, g (x) \,
  \mathrm{d} x \, + \, \frac{1}{2} \,
  \bigl[g (M) + g (N)\bigr] \notag \\
  & \qquad + \, \sum_{j=1}^{k} \, \frac {B_{2j}} {(2j)!}  \left[
    g^{(2j-1)} (N) - g^{(2j-1)} (M) \right] \, + \, R_k (g) \, ,
  \\
  % \label{}
  R_k (g) & \; = \; - \, \frac{1}{(2k)!} \, \int_{M}^{N} \, B_{2k}
  \bigl( x - \Ent{x} \bigr) \, g^{(2k)} (x) \, \mathrm{d} x \, .
  \end{align}
  \end{subequations}

If my cursor is at the beginning of the line of the first label

  \label{EuMaclau}

the command ^c^q^e produces the following correct resuly:

  \begin{subequations}
    \label{EuMaclau}
    \begin{align}
      % \label{}
      \sum_{\nu=M}^{N} \, g (\nu) & \; = \; \int_{M}^{N} \, g (x) \,
      \mathrm{d} x \, + \, \frac{1}{2} \,
      \bigl[g (M) + g (N)\bigr] \notag \\
      & \qquad + \, \sum_{j=1}^{k} \, \frac {B_{2j}} {(2j)!}  \left[
        g^{(2j-1)} (N) - g^{(2j-1)} (M) \right] \, + \, R_k (g) \, ,
      \\
      % \label{}
      R_k (g) & \; = \; - \, \frac{1}{(2k)!} \, \int_{M}^{N} \, B_{2k}
      \bigl( x - \Ent{x} \bigr) \, g^{(2k)} (x) \, \mathrm{d} x \, .
    \end{align}
  \end{subequations}

Let us now assume that my cursor is at the veginning of the first line

  \begin{subequations}

of this environment. Then, the command ^c^q^e should try to format the
whole document. XEmacs -- or rather AUCTeX -- also tries to do this. It
starts ro format and counts the progress until it reaches 90%. Then,
XEmacs freezes and has to be killed.

If I try to get out of the frozen XEmacs via the command ^k^x, the whole
PC freezes and can only be started by turning electricity off and on.

This problem occurs both under KDE and Gnome.

Greetings and best regards

Ernst Joachim
