Is it possible to break page on a double line break in the minted environment?

Question

For a project, I am printing a large amount of source code using Minted. Certain blocks, such as CSS blocks, are fairly short, but are split across pages, which means they are not as readable. Is it possible to get Minted to only insert a page break where there is a double line break in the code?

Answer 1

The plan here is first set interlinepenalty to 10000 so no linebreaking happens normally and then modify the underlying fancyverb to detect a blank line and if so encourage a page break.

The example uses a very small page, just to show the effect.

Before:

After:

\documentclass{article}

\usepackage{minted}

\setlength\topskip{\baselineskip}
\setlength\textheight{12\baselineskip}


\makeatletter
%\showoutput

\def\@wasblank{\PYG {err}{BLANK}}
\def\foo{\aftergroup\ffoo}
\def\ffoo{\goodbreak}% or \clearpage or whatever
\let\zzzz\FV@PreProcessLine
\def\FV@PreProcessLine{%
\ifx\FV@Line\@empty
\def\FV@Line{BLANK}%
\fi
\ifx\FV@Line\@wasblank
\def\FV@Line{\aftergroup\aftergroup\aftergroup\foo}%
\fi
\zzzz}

\begin{document}

%\showoutput
\noindent x1\\x2\\x3\\x4\\x5\\x6\\x7\\x8\\x9\\x10\\x11\\x12
%\tracingall

{
\interlinepenalty10000 %
\begin{minted}{json}
[
  {
    "type": "Room"
    "type1": "Room"
    "typesad": "Room"
    "typde": "Room"
    "tydpe": "Room"
  },

\end{minted}
}
