Yes, that is what I'm playing around with. I have a useful, but
simple export to beamer working. I've been trying without success to
implement beamer's \begin{columns} ... \end{columns} environment.
This is a fairly common construct in beamer that occurs inside some
frames but not in others. It seems natural to put it like this:
("\\section{%s}" . "\\section{%s}")
("\\subsection{%s}" . "\\subsection{%s}")
("\\begin{frame}\\frametitle{%s}" "\\end{frame}" "\\begin{frame}\
\frametitle{%s}" "\\end{frame}")
("\\begin{columns}\\label{%s}" "\\end{columns}" "\\begin{columns}\
\label{%s}" "\\end{columns}")
where the \label{%s} puts the mandatory use of %s somewhere it won't
affect the LaTeX compilation.
The problem with this is that for frames where columns aren't wanted,
simply leaving out the fourth level in org means that everything below
it won't be exported.
This example results in an empty frame (Item 1 and Item 2 are dropped
from the export):
* Section head
** Subsection head
*** Frame title
***** Item 1
***** Item 2
It seems that a placeholder of some kind is needed if the columns
environment isn't wanted.
Initially, I explored using the definition for the unnumbered
sections, like this:
("\\begin{columns}\\label{%s}" "\\end{columns}" "%%\\begin{columns}\
\label{%s}" "%%\\end{columns}")
which would use a LaTeX comment as a placeholder. This won't work
because the switch for numbered/unnumbered sections is set at the file
level and not for individual instances.
Then, I thought to define a do-nothing environment in LaTeX
\newenvironment{nocolumns}{}{}
set it up in .emacs like this:
("\\begin{%s}" "\\end{%s}" "\\begin{%s}" "\\end{%s}")
and then put this in my .org file:
* Section head
** Subsection head
*** Frame title
**** nocolumns
***** Item 1
***** Item 2
But this doesn't work because %s doesn't expand in \\end{%s}. I get
\begin{nocolumns} ... \end{%s}, which LaTeX doesn't like.
So, I'm stumped for now, but still pleased to have a simple export
from org to beamer working, albeit one that produces frames without
columns.
All the best,
Tom
