Re: [Bug-AUCTeX] problems with preview, how it behaves on my system

[jfbu]

dear all,

I just wanted to say that auctex/preview is awesome, and 
this is why I am happy to report that after copying all
the relevant auctex files from the site-lisp of the Emacs 23.1
at my office (Fedora 13 machine), which have the time
stamp 
$Id: preview.el,v 1.285 2010/10/14 19:30:38 angeli Exp $
in preview.el (I don't know if some later patch was applied)

I now have *none* of the problems I reported below: I just
re-byte-compiled everything with my Emacs 24.2 on mac os x,
(adjusting some paths in auctex.el and preview-latex.el due to a
different repertory structure)

and now preview
generation works beautifully, in dvi mode, in pdf mode, 
for the «document», for the «buffer», for single or multi
file projects... perfect!

and direct and reverse search either with xdvi or Skim (for pdf)
work also perfectly (they already did with the newer auctex/preview)

The more modern auctex I thus (reluctantly) replaced with this
ancestor stolen from the machines at my office had the following
time stamp in its auctex/preview.el file
$Id: preview.el,v 1.286 2011/01/23 18:53:55 angeli Exp $

This is only the tag for the preview.el file, I don't know where
to find other time stamps

as an aside, I got rid of very frustrating "error occurred after 
last tex file closed" to get back to some more instructive error
messages; like with this test file copied from
http://lists.gnu.org/archive/html/auctex/2012-03/msg00003.html

\documentclass{article}
\begin{document}
\emph{
\end{document}

I now get

ERROR: File ended while scanning use of \emph .

--- TeX said ---
! File ended while scanning use of \emph .
--- HELP ---
No help available

and this is much better!

please excuse my intrusion on this list where I can
not help the programmers but only give an account of 
my experience. I have been using AUCTeX/preview for
years and I love it.

Sincerely,

Jean-Francois
