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,
r

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

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.

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....))

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.
