If I have the following:

\lit*{\char`\\ b}

How do I combine this with a \hl (highlight) to get a highlighted version of \b?

(\lit is from the syntax package, and \hl is from soul)

The solution for me is usually to change how soul registers the command you are inputting

\documentclass{article}
\usepackage{syntax}
% \usepackage{xcolor} % for colouring
\usepackage{soul}

\soulregister\lit7 % this tells soul to register \lit as non expanded command.
% so the result is \hl{result of lit}
\usepackage{lipsum}
\begin{document}
    Example


\lit{Example}

\hl{Example}

\hl{\lit{Example}}



\end{document}

For more details: How to make \hl (highlighting) to automatically place incompatible commands in \mbox?

Edit

According to quark67's comment, you can create a new command \newcommand{\newlit}[1]{\lit*{#1}} as register that one

\documentclass{article}
\usepackage{syntax}
\usepackage{xcolor} % for colouring
\usepackage{soul}

\newcommand{\newlit}[1]{\lit{#1}}
\soulregister\newlit7 % this tells soul to register \newlit as non expanded command. Yes the 7 at the end is what does it!
% so the result is \hl{result of \lit}
\usepackage{lipsum}
\begin{document}
    Example


\lit{Example}

\hl{Example}

\hl{\lit{Example}}

\hl{\newlit{Example}}



\end{document}

  • by extending this reasoning, you can register any command that hl will take as an argument, like cite. – anis Jan 18 '23 at 19:38
  • Very good solution. I suggest that you expand your solution to more closely match the OP's request. In the preamble, create a new command (as I'm unable to \soulregister the starred version on \lit directly): \newcommand{\newlit}[1]{\lit*{#1}}. Then \soulregister it: \soulregister\newlit7. Then in the document, use "\hl{\newlit{\char`\ b}}" (and probably uncomment the line "\usepackage{xcolor}" as the OP probably would use "\hl" with a colored background. – quark67 Jan 18 '23 at 19:54

    Thanks for the edit, you can modify the comments "register \lit" -> "register \newlit" and "so the result is \hl{result of lit}" -> "so the result is \hl{result of \lit*}" to reflect the changes. – quark67 Jan 18 '23 at 23:15
