}
\begin{document}
  \begin{lstlisting}[language=Nix]
  {
    services.example = {
      enable = true;
      configFile = "${pkgs.suricata}/etc/suricata/suricata.yaml";
      #             ^^^^^^^^^^^^^^^^  <-- this should be red
    };
  }
  \end{lstlisting}
\end{document}

A string (and a multiline string using the two single quotes at the start and end) can contain an inline expression (${...}), which I'd like to mark red.

Any idea how I could implement this?

Thanks in advance!
