# [vox-tech] Fwd: LATEX, ucthesis.cls and changes in font size

Apologies if Pete already posted this.  Obviously checking up with a week
or so of limited online access.  Didn't want to delete it in case Pete
didn't get it posted to vox-tech already, though...

Hey Dylan,

Do yourself a favor and don't ever use verbatim.  There's another package
which is at least an order of magnitude better.  Maybe even two orders of
magnitude.  It's called fancyvrb.

You can change font size quite easily with it:

\usepackage{fancyvrb}

\begin{Verbatim}[fontsize=8]
foobar
\end{Verbatim}

The fancyvrb environment rocks supremely when you include another package
called 'relsize' because it allows you to change fontsize relative to the
current fontsize:

\usepackage{fancyvrb,relsize}

\begin{Verbatim}[fontsize=\relsize{-2}]
foobar
\end{Verbatim}

It also allows you to print line numbers next to the text on the left margin
(note you can also use "numbers=right" to get the numbers to the right of
the text).

\begin{Verbatim}[fontsize=\relsize{-2},numbers=left]
item 1
item 2
item 3
\end{Verbatim}

You can even define your own environment so you don't have to keep putting
the same options within the [] everytime you use fancyvrb:

\DefineVerbatimEnvironment%
{VerbatimProg}%
{Verbatim}%
{numbers=left, fontsize=\relsize{-2}, frame=single}

\begin{VerbatimProg}
int main( int argc, char *argv[] );
\end{VerbatimProg}

BTW, the "frame=single" means "put a frame box around the verbatim text".
Another very cool feature.

One really great thing about fancyvrb is that you __can__ use LaTeX commands
from within the verbatim environment.  OH YESSSSSSSS!!!!!!

\DefineVerbatimEnvironment%
{VerbatimCmdProg}%
{Verbatim}%
{numbers=left, fontsize=\relsize{-2}, frame=single, commandchars=\\\{\}}

Allows you to do...

\begin{VerbatimCmdProg}
int main( void )
\{
printf("hello world\Backslash{n}");   \label{printf_call}
return 0;
\}
\end{VerbatimCmdProg}

Here we call {\tt printf()} at line \ref{printf_call}.

Two things to note when you use the commandchars feature of fancyvrb:

* You have to escape the French braces "{" and "}".
* You also have to jump through a hoop to print backslashes.  Here's how
I defined \Backslash:

\newcommand{\Backslash}[1]{\texttt{\symbol{92}}#1}

This is just a very tiny example of the power of fancyvrb.

Have fun!

Peter
