Hi Arash,
> \begin{frame}
> \begin{itemize}
> \item <1>\textbf{One}
> \item <2>\textbf{Two}
> \end{itemize}
> \end{frame}
This version does fold correctly, but it doesn't produce the same
output as the original example. In particular, here the overlay is
applied to the items themselves, while when writing something like
`\textbf<1>{foo}', the idea is that `foo' will be displayed in bold on
the first slide, and normally for the rest of the slides. Maybe an
example that illustrates the folding problem even better is:
\begin{frame}
\textbf<1>{One} \\
\textbf<2>{Two}
\end{frame}
This is syntactically correct, see section 9.3 of the Beamer user
guide.
I agree that code in the preamble will be extremely hard to fold
correctly. However, maybe it could be an idea to ignore commands that
cannot be folded correctly indstead of displaying an error? I know that
I could just not try to fold the preamble, but right now I have
something like
(add-hook 'LaTeX-mode-hook
(lambda ()
(TeX-fold-mode t)
(add-hook 'find-file-hook 'TeX-fold-buffer t t)))
in my .emacs, every LaTeX buffer I visit gets folder automatically. I
think it would be nicer to just not see the errors.
Have a nice day,
Koen

Hi Koen,
the example above compiles fine, but I think the syntax you're using is
not correct. beamer doc says:
The \item command is overlay specification-aware. If an overlay
specification is provided, the item will only be shown on the
specified slides, see the following example. If the \item command
is to take an optional argument and an overlay specification, the
overlay specification can either come first as in \item<1>[Cat] or
come last as in \item[Cat]<1>.
I.e., \item<alert specification>[item label]<alert specification>
Why do you put alert spec between \textbf and its argument? This version
looks better to me
\begin{frame}
\begin{itemize}
\item <1>\textbf{One}
\item <2>\textbf{Two}
\end{itemize}
\end{frame}
and looks like this when folded where One and Two are boldified:
\begin{frame}
\begin{itemize}
* <1>One
* <2>Two
\end{itemize}
\end{frame}

This one is really hard to fix. Correctly folding preamble macros is
almost impossible.
Best, Arash

Thanks for the detailed report. I tried at least to track down the
culprit for the beamer case, I think a general solution would be to
teach `TeX-find-macro-boundaries' and related functions about <...>
specifications. Unfortunately, I don't have right now the time to fix
it, but this should be a starting point for anyone willing to tackle
this issue. Regarding the second case, I don't think there is an easy
fix for it.
Bye,

Hi!
Some valid LaTeX is parsed incorrectly by AUCTeX folding functions
(i.e. 'TeX-fold-region'), and an annoying error is displayed. Here is
an
example:
===========================
\documentclass{beamer}
\begin{document}
\begin{frame}
\begin{itemize}
\item \textbf<1>{One}
\item \textbf<1>{Two}
\end{itemize}
\end{frame}
\end{document}
===========================
When folded, this code is displayed as follows:
===========================
\documentclass{beamer}
\begin{document}
\begin{frame}
\begin{itemize}
* [Error: No content found]<1>{One}
* [Error: No content found]<2>{Two}
\end{itemize}
\end{frame}
\end{document}
===========================
Another example, which doesn't involve beamer, is the following code:
===========================
\usepackage{titlesec}
\titleformat{\section}{\bfseries}{\thesection}{10pt}{}[\normalfont]
===========================
which displays as:
===========================
\usepackage{titlesec}
\titleformat{[Error: No content
found]}{\bfseries}{\thesection}{10pt}{}[\normalfont]
===========================
Maybe it would be an idea to just not fold things like this where no
content it found, instead of displaying an error?
Thanks!
Koen
