Text Formatting ⇒ fancyvrb + math

[x42bn6]

Hi all,

I'm trying to put mathematical symbols in a Verbatim environment:

Code: Select all

%& -shell-escape

\documentclass[a4paper]{article}

\usepackage{fancyvrb}

\begin{document}
\begin{Verbatim}[commandchars=\\\{\},
codes={\catcode‘$=3\catcode‘^=7}]
x=1/sqrt(z**2) ! $\frac{1}{\sqrt{z^2}}$
\end{Verbatim}
\end{document}

This is basically the example given in the documentation (section 4.1.16).

It fails to compile:

Code: Select all

! Missing number, treated as zero.
<to be read again>
                   `
l.9 codes={\catcode`$=3\catcode`^=7}]

Does anyone know why?

Getting errors just like the one you were getting. I changed my code to this (note it's a back-tick, not a single quote after the catcode):

Code: Select all

\begin{Verbatim}[commandchars=\\\{\},
codes={\catcode`$=3}]

and it ran fine

Code: Select all

$\lambda$

was properly included as the Greek letter lambda, inside the Verbatim section. I couldn't ever figure out how to not get the error when it had both catcodes together \catcode`$=3\catcode`^=7
