Beamer output - ending frames etc

Beamer output - ending frames etc

[Tom Francart]

[-- Attachment #1: Type: text/plain, Size: 3154 bytes --]

Dear list,

I love using pandoc to make presentations through LaTeX beamer. To get the 
output I want, I use a few wrapper scripts, and am wondering whether there 
is a better true pandoc approach to do this.

*1. Ending a frame*
Sometimes it's necessary to insert some LaTeX code in between two frames 
generated by pandoc, for instance to use the beamer \againframe option, or 
to use \appendix, or to use the \setbeamertemplate function. Example:

# Section
## Frame1

Text

\setbeamertemplate{background canvas}[title]

## Frame2


Yields the following LaTeX code:
\section{Section}\label{section}

\begin{frame}{Frame1}

Text

\setbeamertemplate{background canvas}{[}title{]}

\end{frame}

\begin{frame}{Frame2}

\end{frame}


This does not work, because the \setbeamertemplate is wrapped in "Frame1". 
It should go in between \end{frame} and \begin{frame}{Frame2}. Is there a 
way to tell pandoc to end a frame?
(Another problem is that the second argument to setbeamertemplate gets 
wrapped in {}, I solve this using the approach below)

*2. Custom environments*
Pandoc does not parse markdown within \begin{...} and \end{...}. Sometimes 
this is useful though, for example when making a slide with two columns, 
each containing a list of items. I currently work around this by wrapping 
the begin and end statements in <!--- and ---> and using perl like this:

perl -i -pe "s/<\\!---(.+?)--->/\\\\verb\+AAAAAAA\1ZZZZZZZ\+/gm" < .build/$<.gpp > .build/$<.sed.gpp 
pandoc .build/doc.sed.gpp -o .build/doc.pandoc 
perl -i -pe "s/\\\\verb\+AAAAAAA(.+?)ZZZZZZZ\+/\1/gm" <.build/$<.pandoc.tex > .build/$<.tex

I also use this to pass through any Latex code that pandoc does not understand. I believe that the --parse-raw option might partly solve this, but still some of my fancy latex code gets scrambled.

It would be nice if there was a way to do this without using perl.
The very best way would probably be to implement all desired features (such 
as columns) in pandoc, but as this doesn't seem feasible on the short term, 
it might be good to have an easy way to just pass through code with pandoc 
entirely ignoring it. 

*3. Preamble*
I find myself customising the LaTeX template for each document I write, 
which mainly involves adding stuff to the preamble (as I've got the 
workaround above to put arbitrary LaTeX code in the actual document). What 
would be a good way to add stuff to the preamble from the markdown file 
itself? E.g., \usepackage, \newcommand, ...


best regards,
and thanks very much to John for making this fantastic software available!
Tom

To not open another thread, I want to say I'm interested in a solution to 
this too. To me is mainly because I wanted to use the option plain in some 
slides and pandoc do not allow to put as a option

## {.plain}

is silently ignored. I normally resolve issues I have in pandoc with 
filters, but I can't use filters to solve this because the beamer output 
needs \end{frame} tags, so I can't use RawLatex to put

\begin{frame}[plain]
...
\end{frame}

cause two end frames would be output.

You can put preamble stuff in your document if you use YAML front matter 
rather than the simple title block:

---
title: Bla bla bla
author: John Dow
date: insert date here
fontize: 11pt
header-includes:
- \usepackage[english]{babel}
- \setmainfont{Linux Libertine O}
abstract: |
  Lorem ipsum ...
...

It was a reply to the original poster, which stated 3 different questions 
in the same message.
I was replying to the third one of them.
