lstlisting in two columns

Question

I would like to have two listings, side by side.

They have approximately the same length, therefore I don't care about how it's layed out if one part is longer.

I tried

\begin{minipage}{\textwidth}
\begin{parcolumns}{2}
\colchunk{\begin{lstlisting}[caption=code 1,frame=tlrb]{Name}
void code()
{

}
\end{lstlisting}}

\colchunk{\begin{lstlisting}[caption=code 2,frame=tlrb]{Name}
void code()
{

}
\end{lstlisting}}

\colplacechunks
\end{parcolumns}
\end{minipage}

while the border of the listings end up in chunks as follows: chunked listing

Btw I'm using the texlive-package & pdflatex on Ubuntu and the document class is

\documentclass[
a4paper,
10pt,
twoside,
openright,
notitlepage,
parskip=half,
]{scrreprt}

Any idea is appreciated.

You can use two minipages:

\documentclass[
a4paper,
10pt,
twoside,
openright,
notitlepage,
parskip=half,
]{scrreprt}
\usepackage{listings}
\usepackage{parcolumns}
\begin{document}

\noindent\begin{minipage}{.45\textwidth}
\begin{lstlisting}[caption=code 1,frame=tlrb]{Name}
void code()
{

}
\end{lstlisting}
\end{minipage}\hfill
\begin{minipage}{.45\textwidth}
\begin{lstlisting}[caption=code 2,frame=tlrb]{Name}
void code()
{

}
\end{lstlisting}
\end{minipage}

\end{document}

As described here, listings has an option for spreading a listing over two columns. It is not exactly what the OP asks for, but noted here for posterity. – 0 _ Feb 02 '15 at 08:01

Use \begin{lstlisting}[t] if you want the two lstlisting's not to be vertically centered if they are of uneven length. – Chinni Dec 01 '16 at 22:22

If you need lstlistings to be centered top, then you need to use \begin{minipage}[t] – immanis Mar 20 '18 at 13:30
This numbers the listing from 1 to 8 across the two columns. – Christophe De Troyer May 07 '20 at 09:21
@ChristopheDeTroyer you just need to change one of the Listings name (both have name "Name") – Carlos Segarra Aug 04 '21 at 10:57
Using your solution, I got the error "Not in outer par mode" when using the WileyNJD-v2 template :( – Trần Việt Hoàng Sep 30 '21 at 19:34
