Text Formatting ⇒ Referencing a Code

[frodojedi]

Hi all,
I would like to make a reference to a code listed inside the \begin{verbatim}...\begin{verbatim} environment.

How can I do it? Of course I cannot place the \label command inside the verbatim environment.

Any suggestion?

Thanks in advance

Hi,

for referencing you probably would like to give a number to that environment. Numbered environments can be produced by using theorem environments.

For code listings I would use the listings package which is able to produce numbered code listings with captions.

If you're refering to a particular line in your verbatim environment, here's how:

Code: Select all

\begin{Verbatim}[commandchars=\\\{\},numbers=left,numbersep=2pt]
First verbatim line.
Second line.\label{vrb:Important}
Third verbatim line.
\end{Verbatim}

As I previously shown line~\ref{vrb:Important}, it is...

Note that the environment is not verbatim but Verbatim. You'll need the fancyvrb package

Hello,
thanks a lot. I have a problem with the caption when using also a frame.
Actually I am using a template: http://openwetware.org/wiki/LaTeX_templ ... PhD_thesis

When I put the following code I get that the frame is upon the caption.

Code: Select all

\begin{lstlisting}[caption={Example 1},label=lst:example1,frame=single, rulecolor=\color{red}]
\documentclass{article}


\begin{document}

....

\end{document}

\end{lstlisting}

I am using both \usepackage{listings} and \usepackage{fancyvrb}. When I compile in a new document without the template I don´t get that behavior.



Is there a way to overcome this problem?


Thanks in advance

Hi I found the solution, I just added \bigskip in the caption after the text
