Hi Carsten,
I was trying to combine these two variables cleverly but couldn't come
up with a solution that worked. I'd like a certain level, say ***, to
be one thing some times and another thing at other times in the same
output.
It would be neat if org-export-latex-low-levels could be set up like
this:
("\\begin{%s}" "\\end{%s}" "\\begin{%s}" "\\end{%s}")
but when I tried it, %s was expanded only in the first of each pair.
A construct like this would allow the user to export any environment
on a case by case basis.
So, in my case, I could have this in my org file when I want columns:
*** columns
And this in the instances where I don't want columns:
*** nocolumns
(assuming nocolumns is a suitably defined LaTeX command).
All the best,
Tom

Hi Thomas,
I have not really looks at this problem, but would it help to use
a clever combination of org-export-latex-low-levels and org-
export=headline-levels?

Thanks Sebastian. I appreciate the expert assistance. I have a

to Beamer working and was trying to implement automatic export
of columns, too.
The starred sections were going to be placeholders for the
columns heading
level when it wasn't used. I've found that skipping a headline
level in the
source causes the latex exporter to skip over subsequent
inferior levels, so it
isn't possible to assign a heading level to columns and then use
them or not as
the case requires.
You could try to add a class to `org-export-latex-classes'. For
such a
class, you can define a mapping for each headline level:
("my-beamer-class" "\\documentclass...\\usepackage{beamer}"
("\\chapter{%s}" . "\\my-chapter*{%s}")
("\\section{%s}" . "\\my-section*{%s}")
("\\subsection{%s}" . "\\my-subsection*{%s}")
("\\subsubsection{%s}" . "\\my-subsubsection*{%s}")))
I don't know if this is an easy thing to do, since I only did this
once
a long time ago.
But it seems it's worth a try.

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
