## Beamer

Next Tuesday I will have a presentation in the XXXI. EurOpen.CZ conference. I took this event as an opportunity to learn a new presentation software. In the past I have used several presentation software tools. From plain TeX (presented using xdvi(1), or later evince), to MagicPoint.

The candidates were OpenOffice.org's Impress, and Beamer. Since I would like to be able to enter and edit text using vim(1) or at least with vi-like keyboard shortcuts, I have decided to try Beamer. So far it looks nice and configurable (and their manual even had some interesting presentation tips!). There are only two drawbacks:

The first one is that it is TeX-based, so the ugliness and unorthogonality of the TeX command set sometimes cannot be hidden (I am speaking about \begin{frame}[fragile], or the fact that you cannot use \pause in some environments - like matrices in math).

And the second one is, that it is LaTeX-based, and LaTeX, as we all know, is even more disgusting than - say - XML. For example, look at the following code which describes a single frame for MagicPoint:

My first slide

The things I want to talk about:
This one
That one
and also those over there
%page


... and now the equivalent in Beamer:

\begin{frame}
\frametitle{My first slide}
The things I want to talk about:
\begin{itemize}
\item This one
\item That one
\item and also those over there
\end{itemize}
\end{frame}


Hope you see the difference. It is about 80 characters more on each slide. Since the Beamer output looks quite good, I am thinking about writing a conversion tool from the MagicPoint syntax to those verbose LaTeX environments.
