Graphics, Figures & Tables ⇒ two listings side by side to each other

[krislodz]

Hello,

I would like to do something like a code snippet on the left hand side and corresponding data on the right hand side. I use minipage currently but it looks not so nice, minipages are not centered.

Did anyone have some suggestions how can I improve the outcome ?

Here is latex file:

Code: Select all

\documentclass[a4paper,11pt]{article}
\usepackage{hyperref}
\hypersetup{linktocpage}
\usepackage{listings}
\usepackage{amsmath}
\usepackage{array}
\usepackage{tikz}
\usepackage{rotating}
\usepackage{graphicx}
\usepackage{booktabs} % for much better looking tables
\usetikzlibrary{arrows}

\begin{document}
%\begin{table}[ht]
\begin{minipage}[b]{0.5\linewidth}
\centering
\lstset{language=C,label=SliceExaple}
%\lstinputlisting{example_source.c}
\begin{lstlisting}[frame=single, numbers=left, mathescape, label=scopingExample, linewidth = 4cm]
x:=1;
if(x>0)
{
 x:=5;
 while(x>0)
 {
  x:=x-1;
 }
 x:=10;
}
else
{
 write x;
}
x:=15;
\end{lstlisting}
\caption*{Example WHILE code snippet with nested scopes.}
\end{minipage}
\hspace{0.5cm}
\begin{minipage}[b]{0.5\linewidth}
\centering
\begin{lstlisting}[frame=single, mathescape, label=scopesEnteredContents, linewidth = 4cm]
[0]
[0]

[1;0]
[1;0]

[2;1;0]

[1;0]



[3;0]

[0]
\end{lstlisting}
\caption{Contents of scopesEntered for each block.}   
\end{minipage}
%\caption{Example of scope assigning using scopesEntered list.}
%\end{table}
\end{document}

Hi,

the code you posted won't compile due to the use of \caption outside floating environments. Perhaps something like the following is what you are looking for:

Code: Select all

\documentclass[a4paper,11pt]{article}
\usepackage{listings}

\begin{document}

\begin{minipage}[b]{0.45\linewidth}
\centering
\lstset{language=C,label=SliceExaple}
\begin{lstlisting}[frame=single, numbers=left, mathescape,%
  caption={Example WHILE code snippet with nested scopes.}, label=scopingExample]
x:=1;
if(x>0)
{
x:=5;
while(x>0)
{
  x:=x-1;
}
x:=10;
}
else
{
write x;
}
x:=15;
\end{lstlisting}
\end{minipage}
\hspace{0.5cm}
\begin{minipage}[b]{0.45\linewidth}
\centering
\begin{lstlisting}[frame=single, mathescape,%
  title={Contents of scopesEntered for each block.}, label=scopesEnteredContents]
[0]
[0]

[1;0]
[1;0]

[2;1;0]

[1;0]



[3;0]

[0]
\end{lstlisting}
\end{minipage}

\end{document}

You can use the xleftmargin and xrightmargin keys in the optional argument of lstlisting to move listings to the left or the right.

Thanks gmedina, this is what I was aiming for. Juanjo, I was looking also for justification of text within listing but cannot find it anywhere. Can you help with this also ?

I'm not sure about what you understand by justification in this context. Anyway, since your original problem was that the boxes were not centered, I suggested to use two specific keys. To see their effect, in the code of gmedina, replace

Code: Select all

\begin{lstlisting}[frame=single, numbers=left, mathescape,%
  caption={Example WHILE code snippet with nested scopes.}, label=scopingExample]

by

Code: Select all

\begin{lstlisting}[frame=single, numbers=left, mathescape,%
  caption={Example WHILE code snippet with nested scopes.}, label=scopingExample,%
  xleftmargin=1cm,xrightmargin=1cm]

and do analogously with the other lstlisting environment. I think it looks better.

Nice, thanks a lot for help.
