General ⇒ lstlisting in NewDocumentEnvironment

[weltio]

Hello
is it possible to create a lstlisting environment which is numbered and where I get a listof command?

My try:

Code: Select all

Code, edit and compile here:

20
21
22
\documentclass{book}
\usepackage{xparse,tocloft,listings}
\newcommand{\codelist}{Codelist}
\newlistof{code}{cod}{\codelist}
\NewDocumentEnvironment{code}{m}
{
    \begin{lstlisting}
    \refstepcounter{code}
    \addcontentsline{cod}{code}
    {\protect\numberline{\thechapter.\thecode}#1}\par
}
{\caption{#1}\end{lstlisting}}
\begin{document}
\begin{code}{Caption}
Some Code
\end{code}
\listofcode
\end{document}

Run LaTeX here

But this doesnt work since i get:

! Missing \endcsname inserted.
<to be read again>
\global
l.17 \begin{code}{Caption}

Does anybody has an idea to fix it or an alternative?

Why don't you just use »listings« own mechanism?

Just because I'm stupid. Your solution works perfectly. Thank you!
