[Tex/LaTex] lstlisting line wrapping

listingssourcecode

How is it possible to let lstlisting wrap lines?

I've troubles with following block:

\begin{lstlisting}[language=java] 
public class MeasureStationControllerV0Test {   
MeasureStationControllerV0 controller;  
MeasureStation ms = new MeasureStation();   
MeasureStationConfiguration config = new MeasureStationConfiguration();     
DataServer dataserver = new DataServer();

In the PDF output there is an overflow:

overlapping code

Other code-snippets look horrible too.

So have I to manually wrap them or is listings able to handle that?
Why isn't syntax highlighting working?

Use the options breaklines=true and postbreak=\mbox{\textcolor{red}{$\hookrightarrow$}\space} for placing a red arrow at the beginning of the broken line to emphasize the line break.

\documentclass{article}
\usepackage{lmodern}  % for bold teletype font
\usepackage{amsmath}  % for \hookrightarrow
\usepackage{xcolor}   % for \textcolor
\usepackage{listings}
\lstset{
  basicstyle=\ttfamily,
  columns=fullflexible,
  frame=single,
  breaklines=true,
  postbreak=\mbox{\textcolor{red}{$\hookrightarrow$}\space},
}
\begin{document}
\begin{lstlisting}[language=java]
public class MeasureStationControllerV0Test {   
        MeasureStationControllerV0 controller;  
        MeasureStation ms = new MeasureStation();   
        MeasureStationConfiguration config = new MeasureStationConfiguration();     
        DataServer dataserver = new DataServer();
\end{lstlisting}
\end{document}

With the minted package you get nice line breaking and syntax highlighting out-of-the-box. Simply specify the breaklines option on your snippet. The downside is that you have to process the document with the --shell-escape option because the external program pygmentize is used to format the source code.

\documentclass{article}
\usepackage{lmodern} % for bold teletype font
\usepackage{minted}
\begin{document}
\begin{minted}[breaklines,frame=single]{java}
public class MeasureStationControllerV0Test {   
        MeasureStationControllerV0 controller;  
        MeasureStation ms = new MeasureStation();   
        MeasureStationConfiguration config = new MeasureStationConfiguration();     
        DataServer dataserver = new DataServer();
\end{minted}
\end{document}

As @egreg recommended, the bashful package is specifically designed for this. Quoting from the user manual:

...bashful provides a convenient interface to TEX’s primitive \write18—the execution of shell com- mands from within your input files, also known as shell escape. Text between \bash and \END is executed by bash, a popular Unix command line interpreter. Various flags control whether the executed commands and their output show up in the printed document, and whether they are saved to files.

Although provisions are made for using shells other than bash, this package may not operate without modifications on Microsoft’s operating systems.

Note that this requires -shell-escape option to be specified.

Here I have used only basic bash commands. I suspect that you could do something similar with the Haskell interpreter.

enter image description here

The first line of the bash script file begins with a %, so I started the listings form line 2, and left the first line blank. When you initiate the \bash command, you provide a file name for the .sh bash file and the output file. Then use lstinputlisting to reincorporate the contents of that file back into the .tex file.

\documentclass{standalone}
\usepackage{xcolor}
\usepackage{bashful}
\usepackage{listings}

\lstdefinestyle{BashInputStyle}{
  language=bash,
  firstline=2,% Supress the first line that begins with `%`
  basicstyle=\small\sffamily,
  numbers=left,
  numberstyle=\tiny,
  numbersep=3pt,
  frame=tb,
  columns=fullflexible,
  backgroundcolor=\color{yellow!20},
  linewidth=0.9\linewidth,
  xleftmargin=0.1\linewidth
}

\lstdefinestyle{BashOutputStyle}{
  basicstyle=\small\ttfamily,
  numbers=none,
  frame=tblr,
  columns=fullflexible,
  backgroundcolor=\color{blue!10},
  linewidth=0.9\linewidth,
  xleftmargin=0.1\linewidth
}


\begin{document}
\bash[verbose,scriptFile=hello.sh,stdoutFile=hello.tex]

echo "Hello World!"
echo "Today is" `date`
echo ""
echo "Disk usage is:"
df
\END
\par\noindent
Executing the following code in \textbf{bash}
\lstinputlisting[style=BashInputStyle]{hello.sh}
%
yields the following output:
\lstinputlisting[style=BashOutputStyle]{hello.tex}
\end{document}

[Tex/LaTex] lstlisting environment ignores tabs

use it this way:

\documentclass{beamer}
\usepackage{listings}
    \lstset{
    language=Java,
    tabsize=8,
    keepspaces,
    extendedchars=true,
    rulecolor=\color{black},
    basicstyle=\footnotesize,
    aboveskip=5pt,
    upquote=true,
    columns=fixed,
    showstringspaces=false,
    extendedchars=true,
    breaklines=true,
    frame=single,
    showtabs=true,
    showspaces=false,
    showstringspaces=false,
}
\begin{document}
\defverbatim\lst{%
\begin{lstlisting}
    public class Teddy {
        public MethodName(String name, int var) {
            this.name = name;
        }
    }
\end{lstlisting}
}
\begin{frame}
\lst
\end{frame}
\end{document}
