## Using overlays for source code listings in LaTeX Beamer

Filed under: Blog — krkhan @ 9:33 pm

The standard way of including source code listings in Beamer is to use the semiverbatim environment. Needless to say, it does not provide all the syntax highlighting and line-numbering love of the listings package. Combine the two and you have something pretty as well as extremely helpful in delivering presentations which have code:

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 38 39 40 41 42 43 44 45 46 47 \documentclass{beamer}   \setbeamercovered{transparent}   \usepackage{pxfonts} \usepackage{listings}   \begin{document}   \lstset{language=python, numbers=left, numberstyle=\tiny, showstringspaces=false, aboveskip=-40pt, frame=leftline }   \begin{frame}[fragile] \frametitle{\texttt{parrot.py}} \begin{semiverbatim} \pause \begin{lstlisting} if __name__ == "__main":   \end{lstlisting}   \pause \begin{lstlisting}[firstnumber=last] print "Oh yes, the, uh, the Norwegian Blue..." print "What's, uh... What's wrong with it? "   \end{lstlisting}   \pause \begin{lstlisting}[firstnumber=last] print "I'll tell you what's wrong with it, my lad." print "'E's dead, that's what's wrong with it!"   \end{lstlisting} \end{semiverbatim} \end{frame}   \end{document}

## The Defense

Filed under: Blog — krkhan @ 10:08 pm

Continuing the process of presenting my proposal for the graduation project, I was required to do a presentation. Now, I have never really liked PowerPoint and for more reasons than it being a product of Microsoft (I was never really into OpenOffice.org Impress either).

In fact, I have never liked doing presentations in the first place. My preferred means of communicating an idea is through written material or face-to-face discussions. Anyhow, seeing as I had to do a formal presentation, I turned towards the solution that would provide some additional attraction for me: Beamer.

Resin transfer molding is a process provided by Romeorim, one of the strongest authority in the field, based on hardening the liquid mold component before being injected. This process usually uses fibers of glass, but even the carbon and organic fibers are being used more and more.

After fiddling around with my .tex for a few hours, I was able to create something which looked [*] far more professional, sexier and informative than anything I had ever created using traditional presentation software:

ittc-defense-presentation.pdf

To view the presentation you have to open it in “Slide Show” mode of your favorite PDF reader. What totally blew me away was the ease with which I could create lovely bibliographic references, mathematical equations and little fun things like navigational bar on top of every page. Perhaps it’s got to do something with the mindset of a programmer, but I certainly became more productive with Beamer within a couple of hours than I had been throughout my experience with PowerPoint/Impress.

[*] Whether they were professional, sexy or informative is a totally different matter and has very little to do with either LaTeX or Beamer.
