[new exporter] #+TOC in beamer export

[new exporter] #+TOC in beamer export

[Andreas Leha]

Hi all,

from a recent thread I learned about #+TOC (there's always something new
to learn about org mode).

I'd like to use it in a beamer document.  Here I find it hard to use
because it introduces its own frame.

My question basically is:  How is this supposed to be used in a beamer
doc?
(And would it not be easier if it did not introduce its own frame?)

Here is a sample file to test (provided that you have a latex-class
"beamer" defined in org-mode)

#+begin_src org
#+TITLE: Something
#+LaTeX_CLASS: beamer
#+LaTeX_CLASS_OPTIONS: [presentation]
#+COLUMNS: %45ITEM %10BEAMER_env(Env) %10BEAMER_act(Act) %4BEAMER_col(Col) %8BEAMER_opt(Opt)
#+PROPERTY: BEAMER_col_ALL 0.1 0.2 0.3 0.4 0.5 0.6 0.7 0.8 0.9 0.0 :ETC
#+OPTIONS: toc:nil H:2


* Intro
** Motivation
** Challanges

#+TOC: headlines 2

* Main Part
** One
** Two
#+end_src


This produces for me:
,----
| [...]
| 
| \section[Intro]{Intro}
| \label{sec-1}
| \begin{frame}[label=sec-1-1]{Motivation}
| \end{frame}
| \begin{frame}[label=sec-1-2]{Challanges}
| \begin{frame}\setcounter{tocdepth}{2}
| \tableofcontents
| \end{frame}
| \end{frame}
| \section[Main Part]{Main Part}
| \label{sec-2}
| \begin{frame}[label=sec-2-1]{One}
| \end{frame}
| \begin{frame}[label=sec-2-2]{Two}
| \end{frame}
|
| [...]
`----


I'd prefer to create the frame myself, so that I see the structure of
the presentation, but that does not work either for me:

#+begin_src org
#+TITLE: Something
#+LaTeX_CLASS: beamer
#+LaTeX_CLASS_OPTIONS: [presentation]
#+COLUMNS: %45ITEM %10BEAMER_env(Env) %10BEAMER_act(Act) %4BEAMER_col(Col) %8BEAMER_opt(Opt)
#+PROPERTY: BEAMER_col_ALL 0.1 0.2 0.3 0.4 0.5 0.6 0.7 0.8 0.9 0.0 :ETC
#+OPTIONS: toc:nil H:2


* Intro
** Motivation
** Challanges

* TOC								    :B_frame:
  :PROPERTIES:
  :BEAMER_env: frame
  :END:
#+TOC: headlines 2

* Main Part
** One
** Two
#end_src

It seems useful to keep frame around TOC generated from toc:t option.
But we could remove it from TOC generated from #+TOC keywords.

Is that what you have in mind?

Thanks for taking this further.  Indeed, for the toc:t triggered TOC the
frame is absolutely useful.

So, I like your suggestion very much.

Best,
Andreas

I'm not sure what a \tableofcontents outside a frame would look like.
Can someone show an example?

I also had another thought; sometimes for long presentations, I use
something like this:

  \AtBeginSubsection[]{
    \ifthenelse{
      \(\value{section}=1\)\AND\(\value{subsection}=1\)
    }{}
    {
      \begin{frame}<beamer>
        \frametitle{Outline}
        \tableofcontents[currentsubsection]
      \end{frame}
    }
  }

At the moment I put it in as one long LaTeX_HEADER line.  But would it
be possible to leverage #+TOC: into having a similar effect?  It might
then provide a greater degree of control where you want the toc frame to
appear.

Cheers,

I think that the idea behind a frameless TOC is that you provide your
own frame for it.

It makes sense since #+TOC: allows to control accurately the location of
your table of contents.

I think this kind of control should really belong to specific latex
code.

A TOC limited to current section sure sounds seducing, but I'm not sure
how to achieve this in LaTeX.

That makes a lot of sense.  :)

I think you are right.  I'll see if can find a nice way to do this in
LaTeX, I'll share if I find something.

Perhaps package minitoc is what you are looking for?
I don't know if it is usable within beamer.

Something like this?
  \tableofcontents[sectionstyle=show/hide, subsectionstyle=show/show/hide]


Full example:
#+begin_src org
#+TITLE: Something
#+LaTeX_CLASS: beamer
#+LaTeX_CLASS_OPTIONS: [presentation]

#+PROPERTY: BEAMER_col_ALL 0.1 0.2 0.3 0.4 0.5 0.6 0.7 0.8 0.9 0.0 :ETC
#+OPTIONS: toc:nil H:3

Actually, I am looking for a way to do it in regular (i.e. non-Beamer)
LaTeX. I guess your code only applies to Beamer documentclass.

Thanks anyway.

Sorry.  Did not follow this thread closely.  Yes, this is
beamer-specific.  For non-beamer documents, Robert's suggestion of the
minitoc package is good.
