[Tex/LaTex] Background overflows when using rounded corners for listings (package: `listings`)

backgroundscolorlistingsrounded-corners

I'm using listings to list code in my document, and I want the code to be displayed in a frame with rounded corners and a grey background color. But the background overflows the frame, as if the frame was square.

Here's a minimal example:

\documentclass[a4paper, 11pt]{article}

\usepackage{color}
\usepackage{listings}

\begin{document}

\lstset{basicstyle=\footnotesize\ttfamily, xleftmargin=1em, xrightmargin=1em,
  frame=single, framesep=1em, frameround=tttt,
  backgroundcolor=\color[rgb]{0.85, 0.85, 0.85}, captionpos=b}
\begin{lstlisting}
bla bla bla
\end{lstlisting}

\end{document}

Result:

Any idea on how to fix this?

EDIT

I got the example working now. The problem was due to old versions of required packages.

Best Answer

Based on the link in my comment I created an environment in which you can use the lstlistings-environment:

Code

\documentclass[a4paper, 11pt]{article}

%\usepackage{color} loaded by tikz and you should use xcolor instead ...
\usepackage{listings}
\usepackage{tikz}

% set listings
\lstset{%
    basicstyle=\footnotesize\ttfamily,
%   captionpos=t,
    framesep=5em,
}

% define backgroundcolor
\definecolor{bggray}{rgb}{0.85, 0.85, 0.85}

% add frame environment
\usepackage[%
    framemethod=tikz,
    skipbelow=\topskip,
    skipabove=\topskip
]{mdframed}
\mdfsetup{%
    leftmargin=0pt,
    rightmargin=0pt,
    backgroundcolor=bggray,
    middlelinecolor=black,
    roundcorner=10
}

\usepackage{etoolbox}% >= v2.1 2011-01-03
\BeforeBeginEnvironment{lstlisting}{\begin{mdframed}\vspace{-0.7em}}
\AfterEndEnvironment{lstlisting}{\vspace{-0.5em}\end{mdframed}}

% needed for \lstcapt
\def\ifempty#1{\def\temparg{#1}\ifx\temparg\empty}

% make new caption command for listings
\usepackage{caption}
\newcommand{\lstcapt}[2][]{%
    \ifempty{#1}%
        \captionof{lstlisting}{#2}%
    \else%
        \captionof{lstlisting}[#1]{#2}%
    \fi%
    \vspace{0.75\baselineskip}%
}

% only for testing ...
\usepackage[english]{babel}
\usepackage{blindtext}

\begin{document}
\blindtext
%
\begin{lstlisting}
Foo {
    Bazzzzz }
Bar
\end{lstlisting}
\lstcapt{Test}
%
\blindtext
%
\begin{lstlisting}
Foo
\end{lstlisting}
\lstcapt[Short descrpition]{Another long description. Another long description.
    Another long description.}
%
\blindtext
%
\lstlistoflistings
\end{document}

Limitation

~~This solution works only for non page breaking listings. See the answers to Test if a paragraph has a page break in it? for an idea how this could work.~~ See Update 3

Update

I put this three lines to the above example to patch the lstlisting environment dircetly. So there’s no need to put it manually in \begin{code} … \end{code} anymore.

\usepackage{etoolbox}
\BeforeBeginEnvironment{lstlisting}{\begin{code}}
\AfterEndEnvironment{lstlisting}{\end{code}}

Update 2

I created a new command \lstcapt[<Short>]{<Text>} to set a caption out of the frame, and added it to the above example code.

Update 3

I changed to mdframed instead of using TikZ directly to solve the page breaking problem as Marco suggested.

Update 4

Please note that this code needs etoolbox v2.1 or higer …

[Tex/LaTex] get a shadowbox with rounded corners? (using `listings` package)

Next code uses tcolorbox to format the shadowed box where code is inserted through listing package. Size, color and format of shadows can be adapted to ones taste.

\documentclass{article}

\usepackage[most]{tcolorbox}

\newtcblisting{pythoncode}[2][]{%
    enhanced, title=#2, colframe=blue!50!black, 
    colback=blue!10!white, 
    fonttitle=\ttfamily, coltitle=white,
    attach boxed title to top left = {xshift=5mm,yshift=-2mm} ,
    boxed title style={size=small, colback=blue!75!black},
    width=.5\linewidth,
    listing only,listing options={language=Python, basicstyle=\ttfamily\footnotesize},#1}

\begin{document}

\begin{pythoncode}[drop shadow]{hello.py}
#!/usr/bin/env python
def main():
    print "Hello, World!"
if __name__ == '__main__':
    main()
\end{pythoncode}

\begin{pythoncode}[drop fuzzy shadow]{hello.py}
#!/usr/bin/env python
def main():
    print "Hello, World!"
if __name__ == '__main__':
    main()

[Tex/LaTex] rounded corners using the framed package

I am afraid that framed package cannot do that alone. But you can redefine \fbox or \FrameCommand to obtain this results with the usual command \fbox or the framed environment.

This need some complex TeX definitions that are already included in fancybox.sty. So, the most simple solution in to load also fancybox package and then make a very simple definitions including \ovalbox or \Ovalbox. Example:

\documentclass{article}
\usepackage{fancybox,framed}
\renewcommand\fbox[1]{\Ovalbox{#1}}
\renewcommand*\FrameCommand{\ovalbox}
\begin{document}
Some text 
\begin{framed}
A framed environment example ...
\end{framed}
Some text
\vspace{2cm}
Some text 
\fbox{Simple framed box} 
Some text 
\end{document}

But I think that is more clear, more intuitive and less problematic use \Ovalbox or \ovalbox directly and left \fbox for rentangular boxes.

About colors asked in azetina comment, as far I now fancybox do not have color options, but is not difficult to obtain a colored border. See Enumerate over two columns in tabular environment for a example. A colored background seem more complicated (for me), so my advise is left definitively \fbox and fancybox and use the tcolorbox or mdframed packages, both excellent alternatives with many interesting options. There are a lot examples here, just some are in:
