[Tex/LaTex] Various \textcolor within lstlisting

colorlistings

How can you set various words in your lstlisting to various text colors?

For instance, I want the word "fail" to appear in red and the word "pass" in green.

I have the feeling there should be some easy escape possibility!?

What did not work

I tried using the parameter

escapeinside={(*@}{@*)}

and then within the lstlisting

(*@\color{red}@*) fail (*@\color{black}@*)

But this has no effect.

Therefore, I've tried

$\textcolor{red}{\lstinline!fail!}$

but listings does not like nested lstinline within lstlistings.

Complex solution

a not quite suitable solution is described in \textcolor within lstlisting?: it is intended for one color only, so I would have to add something like

moredelim=**[is][\color{red}]{@}{@},

for every color I use 🙁

Best Answer

The escaped part is a group, so color command issued there are lost at the end. There is no official way to set a color globally but you can look here How can I change the text color in such a way that the effect transcends groups?.

Beside this you can try to set the color with \aftergroup (but color of keywords will overwrite this settings):

\documentclass{article}
\usepackage[T1]{fontenc}
\usepackage{xcolor}
\usepackage{listings}

\begin{document}

\def\redcolor{\color{red}}
\def\blackcolor{\color{black}}
\begin{lstlisting}[escapechar=@]
#@\aftergroup\redcolor@include@\aftergroup\blackcolor@ <fstream.h>
void main () {
fail
pass
}
\end{lstlisting}

\end{document}

You should provide a MWE. However, I have the following answer:

\documentclass{article}
\usepackage{listings}

\usepackage{xcolor}

\lstdefinestyle{base}{
  language=C,
  emptylines=1,
  breaklines=true,
  basicstyle=\ttfamily\color{black},
  moredelim=**[is][\color{red}]{@}{@},
}

\begin{document}

\begin{lstlisting}[frame=single,style=base]
   public class A<T> extends B<T> {
      @Stack stack@;  //how can I achive this? Nothing should change, except for the textcolor. This code just prints the \textcolor command though.

       //ctor
       public A() {};
   }
\end{lstlisting}

[Tex/LaTex] Higher Asterisks in lstlisting environment

You can change the command listings use when processing the asterisk:

\documentclass{scrbook}
\usepackage[T1]{fontenc}
\usepackage{lmodern}
\usepackage{listings}

\usepackage{color}
\definecolor{stringColor}{RGB}{42,0.0,255}
\definecolor{keyword1Color}{RGB}{63,127,95}
\definecolor{keyword2Color}{RGB}{63,127,200}
\definecolor{singleLineCommentColor}{RGB}{127,0,85}
\definecolor{multiLineCommentColor}{RGB}{200,0,127}

\lstdefinelanguage{test}{
    basicstyle=\linespread{0.83}\small\ttfamily, % Global Code Style
    %literate=*{*}{\normalfont{*}}1,
    morecomment=[l][\color{singleLineCommentColor}]{//},
    morecomment=[s][\color{multiLineCommentColor}]{/*}{*/},
    morestring=[b]",
    morestring=[b]',
    commentstyle=\color{commentColor},
    keywordstyle=[1]{\bfseries\color{keyword1Color}},
    keywordstyle=[2]{\bfseries\color{keyword2Color}},
    stringstyle=\color{stringColor},
    %...
}
