How to place a code snippet using minted inside a tcolorbox?

Question

This is a piece of my LaTeX code:

\documentclass[a4paper,oneside]
\usepackage{minted}
\usepackage{tcolorbox}
\tcbuselibrary{breakable,skins}
\usepackage{etoolbox}
\usepackage{fancyvrb}

\begin{document}
\begin{tcolorbox}[breakable=true]
\centering
\RecustomVerbatimEnvironment{Verbatim}{BVerbatim}{}
\inputminted{gnuplot}{script.txt}
\end{tcolorbox}  
\end{document}

This is the script.txt file:

This is how the output looks like:

I am trying to fit the minted code in the tcolorbox, such that the code also spans across pages. Can someone guide me in the right way?

Answer 1

I think I found the cause of the problem. Your use of \RecustomVerbatimEnvironment seems to make the minted code unbreakable. If you omit this (and thereby also omit centering), your code is breakable:

\begin{filecontents*}{script.txt}
Bla bla bla bla bla.
Blub blub blub.
Bla bla bla bla bla.
Blub blub blub.
Bla bla bla bla bla.
Blub blub blub.
Bla bla bla bla bla.
Blub blub blub.
Bla bla bla bla bla.
Blub blub blub.
Bla bla bla bla bla.
Blub blub blub.
Bla bla bla bla bla.
Blub blub blub.
Bla bla bla bla bla.
Blub blub blub.
Bla bla bla bla bla.
Blub blub blub.
Bla bla bla bla bla.
Blub blub blub.
\end{filecontents*}

\documentclass[a4paper,oneside]{report}
\usepackage{minted}
\usepackage{tcolorbox}
\tcbuselibrary{breakable,skins}
\usepackage{etoolbox}
\usepackage{fancyvrb}

\begin{document}

\rule{1pt}{14cm}

\begin{tcolorbox}[breakable,enhanced]
%\centering
%\RecustomVerbatimEnvironment{Verbatim}{BVerbatim}{}
\inputminted{gnuplot}{script.txt}
\end{tcolorbox}
\end{document}

Update:

You get the same result, if you use the minted library of tcolorbox and its \tcbinputlisting command instead of putting \inputminted into a tcolorbox.

With your provided script.txt plus setting minted options={breaklines} for line breaking, this gives:

\documentclass[a4paper,oneside]{report}
\usepackage{minted}
\usepackage{tcolorbox}
\tcbuselibrary{breakable,skins,minted}
\usepackage{etoolbox}
\usepackage{fancyvrb}

\begin{document}

\tcbinputlisting{
  listing file=script.txt,
  minted language=gnuplot,
  minted options={breaklines},% <-- put other minted options inside the brackets
  breakable,enhanced,% <-- put other tcolorbox options here
  listing only
}

\end{document}

If you have many gnuplot inputs, you can wrap all settings into a new macro using \newcommand or \newtcbinputlisting (from tcolorbox).

For example, create a new macro \gnuplotinput like the following:

\documentclass[a4paper,oneside]{report}
\usepackage{tcolorbox}
\tcbuselibrary{breakable,skins,minted}

\newtcbinputlisting{\gnuplotinput}[2][]{%
  listing file={#2},
  minted language=gnuplot,
  minted options={breaklines},% <-- put other minted options inside the brackets
  breakable,enhanced,% <-- put other tcolorbox options here
  listing only,#1
}

\begin{document}

\gnuplotinput{script.txt}

\end{document}
