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

Although you could always add

\beamerdefaultoverlayspecification{<+->}

to the preamble.

You can warp this code in #+begin_latex ... #+end_latex
