Is it possible to use tikzmark inside minted?

Question

As I've pointed out in a related question, I'd like to have some arrows pointing to parts of a source-code listing.

I know this is possible with the listings package, but is it possible with minted? That is, is there a way that I can insert a mark at a specific point inside the code minted is displaying?

Answer 1

Yes, it appears to work, you just need to specify an escape character (? here) to minted so you can insert the \tikzmark.

\documentclass{article}
\usepackage{minted}
\usepackage{tikz}
\usetikzlibrary{tikzmark}

\begin{document}


\begin{minted}[escapeinside=??]{py}
def f(x):
    y = x?\tikzmark{here}?2
return y
\end{minted}


See this bit:
\begin{tikzpicture}[remember picture]
\draw[overlay, ->, line width=5pt, red] (0,0) -- (pic cs:here);
\end{tikzpicture}
\end{document}

Answer 2

Just for the fun of it, and in case somebody else stumbles on this: This idea can be combined with the standalone package as well, with a bit of tweaking:

\documentclass[multi=apage,varwidth=8cm]{standalone}
\usepackage{minted}
\usepackage{tikz}
\usetikzlibrary{tikzmark}

\newenvironment{apage}[0]{}{}

\begin{document}

\begin{apage}

  \begin{tabular}{p{0.3\textwidth}p{0.3\textwidth}}
    \begin{minted}[escapeinside=??]{py}
      def f(x):
        y = x?\tikzmark{here1}?2
      return y
    \end{minted}
    &
    \begin{minted}[escapeinside=??]{py}
      def f(x):
        y = x?\tikzmark{here2}?2
      return y
    \end{minted}
  \end{tabular}
  

  \begin{tikzpicture}[remember picture]
    \draw[overlay, ->, line width=5pt, red]
    (pic cs:here1) -- (pic cs:here2);
  \end{tikzpicture}

\end{apage}

\end{document}
