LaTex: Possible to include large block of Regex?

Question

Hi,

is it possible to include a large block of a regex (like this one: http://www.ex-parrot.com/pdw/Mail-RFC822-Address.html) without escaping all colliding characters first?

i think of something like

\begin{following_section_will_not_be_parsed_by_latex} (a+?b) \end{...}

thank you!

Andrew

Answer 1

Use a verbatim block. But it won't look very nice :(

Answer 2

Solved it!

you can include \usepackage{listings}

and then use \begin{lstlisting} [code|regex|whatever] \end{lstlisting}

thank you anyways,

Answer 3

Look at fancyvrb package. From the README:

The `fancyvrb' package provides very sophisticated facilities for reading and writing verbatim TeX code. Users can perform common tasks like changing font family and size, numbering lines, framing code examples, colouring text and conditionally processing text.

So you can do something like:

\documentclass{article}
\usepackage{fancyvrb}
\begin{document}
\begin{Verbatim}[fontsize=\small,frame=single,label=RFC822 regexp]
...
\end{Verbatim}

In order to not clutter your Latex file with the huge regex, you can include a file verbatim as well.
