Hi,
 Following an earlier suggestion on the list:
http://thread.gmane.org/gmane.emacs.orgmode/15010/focus=15077

I added the following to my .emacs file:

(add-to-list 'org-export-latex-classes
             '("beamer"
	       "\\documentclass[11pt]{beamer}
                \\usepackage[utf8]{inputenc}
                \\usepackage[T1]{fontenc}
                \\usepackage{amsmath,amssymb,graphicx,bm,multirow,colortbl,vector}
                \\usepackage{hyperref}
                \\usepackage{verbatim}
                \\setbeameroption{show notes}
                \\usetheme{Goettingen}
                \\useoutertheme{infolines}"
	       ("\\begin{frame}\\frametitle{%s}\\begin{itemize}"
"\\end{itemize}\\end{frame}"
		"\\begin{frame}\\frametitle{%s}\\begin{itemize}" "\\end{itemize}\\end{frame}")
	       ("\\item{%s}" . "\\item*{%s}")))

However, this gives me the error:
Debugger entered--Lisp error: (void-variable org-export-latex-classes)

I am using Emacs 23.1 and org-mode 6.29trans in Windows Vista.

Any suggestions to fix the error are appreciated.

For this line to be working, the variable must have been defined.

Either precede the code with

  (require 'org-latex)

or wrap it into

(eval-after-load "org-latex" '(add-to-list....))

Thanks! That worked.

I had a a couple more questions about using latex-export.

1. 
* Slide 5
\uncover<2->
{appear from slide 2 on\\ }
\uncover<3-4>
{appears from 3 to slide 4\\ }
\uncover<4>{appears on slide 4\\ }
\uncover<3->{appears from slide 3 on\\ }

gets output as:

\begin{frame}\frametitle{Slide 5}
\label{sec-5}
\uncover<2->
\{appear from slide 2 on\\ \}
\uncover<3-4>
\{appears from 3 to slide 4\\ \}
\uncover<4>\{appears on slide 4\\ \}
\uncover<3->\{appears from slide 3 on\\ \}
\end{frame}

Is there a way to avoid { and } being output as \{ and \} , respectively.

2. Is there a way to add an attribute to latex lists (itemize, enumerate,
description} so that:

* Slide 1
 - x
 - y
 - z

gets output as:
\begin{itemize}[<+->]
\item x
\item y
\item z
\end{itemize}

Thanks again for the help, and the invaluable org-mode.

This seems like a very common thing to want to do, but am I right in
thinking that it's also very hard to get right because the frame
environment is not really a sectioning environment?

As I understand things, the way we export to latex is to insert
sectioning commands, and drop translated content in between.

However, this doesn't seem like the right model for Beamer.

Consider a crude talk outline like this:


* Here's a simple point

Some material here

* Here's a complex point

** First component point

Explanation

** Second component point

More explanation....


The "right" way to translate this is something like

\section{Here's a simple point}
\begin{frame}
\frametitle{Here's a simple point}
...
\end{frame}

\section{Here's a complex point}
\begin{frame}
\frametitle{First component point}
....
\end{frame}
\begin{frame}
\frametitle{Second component point}
....
\end{frame}

------------------------------------------

I.e., there's some rule like "If a header has text under it, then treat
it as a frame, otherwise, just treat it as a section header."

You see this above, where the two top-level headers are treated differently.

I can't think of any obvious way to translate org to beamer that doesn't
require choosing a /specific/ level of the outline as "the level that
corresponds to a frame," and doing that seems to seriously compromise
the outlining flexibility of org-mode.

Am I missing something here?  Is there some better way to figure out how
to introduce frames, instead of treating them as sectioning headers?

thanks,
R

Here's another challenge --- is there a good way to handle this in the
exporter?

If you use VERBATIM in a beamer frame, then you need to add the optional
argument "fragile" to the environment, like this:

\begin{frame}[fragile]

instead of just

\begin{frame}

I'd be surprised if there was a good method for this, but thought I'd ask...

best,

Have you tried adding it unconditionally in the org-export-latex-classes
alist?  I don't think it hurts to have it on by default (it costs a bit
of performance maybe, but it should not be noticeable.) OTOH, verbatim
is a can of worms: it should be avoided if at all possible. It cannot be
used in moving arguments (at all: see

http://www.tex.ac.uk/cgi-bin/texfaq2html?label=verbwithin

for details.) - and what beamer does with it is a mystery to me - hence
the "avoid at all costs" statement.

HTH,
Nick

I don't think the "avoid at all costs" is tenable when using beamer,
because of the need to insert code.

I have used alltt as well as verbatim, but it seems just as fragile.

I hope to provide a proposed beamer template sometime soon.

best,
Robert
