I am trying to highlight a specific line inside a listing with listinline. The code I am currently using looks like this:

\begin{lstlisting}[escapechar=!]
class A {
  void m() {
    B b = ...
    !\fbox{b.n();}!
  }
}   
\end{lstlisting}

This works somewhat, however the text inside the fbox is obviously not processed by the listings package. Using !fbox{\lstinline{b.n();}}! produces an error.

It seems to me that listings doesn't allow any verbatim code between two escape characters. One solution would be to store the \lstinline{b.n();} in a box outside the lstlisting and use the box inside it:

\documentclass{article}

\usepackage{listings}
\usepackage{newverbs}

\newsavebox{\mybox}
\begin{document}
\begin{lrbox}{\mybox}
    \lstinline{b.n();}%
\end{lrbox}

\begin{lstlisting}[escapechar=!]
class A {
  void m() {
    B b = ...
    !\fbox{\usebox\mybox}!
  }
}   
\end{lstlisting}

\end{document}

  • That is a bit odd, because !\verb|...|! is allowed – daleif Apr 05 '11 at 14:16
  • @daleif: Yes, it is odd. – Martin Scharrer Apr 05 '11 at 14:45
  • @MartinScharrer How can I do this but inside the Verbatim environment, and with an fbox containing several lines? – mljrg Jan 09 '13 at 23:56
  • Put the Verbatim environment inside lrbox and a minipage environment and use \fbox{\usebox\mybox} again. You can also use my adjustbox package and wrap Verbatim with \begin{adjustbox}{minipage=\linewidth,fbox} .. \end{adjustbox}. Feel free to open a follow-up question if this doesn't help you enough. – Martin Scharrer Jan 10 '13 at 07:49
