LaTeX forum ⇒ Text Formatting ⇒ Highlighting a Chunk of Code within a lstlisting

[gadgetto]

Hi everyone,

I have got some lines of code inserted by lstlisting:

Code: [Select all] [Expand/Collapse] [Download] (untitled.tex)

\begin{lstlisting}
public class MyRunnable implements Runnable{
	String name;
	public MyRunnable(String name){
		this.name = name;
	}
\end{lstlisting}

Now I want to hightlight for example >>class MyRunnable<<. An easy way is to use colorbox:

Code: [Select all] [Expand/Collapse] [Download] (untitled.tex)

\begin{lstlisting}
public §\colorbox{yellow}{class MyRunnable}§ implements Runnable{
	String name;
	public MyRunnable(String name){
		this.name = name;
	}
\end{lstlisting}

It works fine, but you are losing the syntax highlighting inside a colorbox.

Is there a way to save the syntax highlighting???
I tested to insert a "\lstinline" in the "lstlisting", but I had no success

Has anyone an idea how to solve my problem???

best regards,
Gadgetto

You can use hf-tikz:

Code: [Select all] [Expand/Collapse] [Download] (untitled.tex)

\documentclass{scrartcl}
\usepackage{listings}
\lstset{escapechar=§}
 
\usepackage[norndcorners,customcolors]{hf-tikz}
\hfsetbordercolor{yellow}
\hfsetfillcolor{yellow}
 
\begin{document}
\begin{lstlisting}
public §\tikzmarkin{glw}§class MyRunnable§\tikzmarkend{glw}§ implements Runnable{
         String name;
         public MyRunnable(String name){
                 this.name = name;
         }
\end{lstlisting}
\end{document}

Run twice to get the result:
