I am writing text that should be displayed as a code block with some fancy math mode characters.

\documentclass{article}
\usepackage{listings}

\begin{document}
\lstinline[mathescape=true]{Integer $\not \sim$ String}
\end{document}

This renders as expected. However, I want to wrap this use of \lstinline in a customily named command, to be able to easily change colouring, type family, etc.. for all occurrences later on. What I want is:

\documentclass{article}
\usepackage{listings}

\begin{document}
\newcommand{\codem}[1]{\lstinline[mathescape=true]{#1}}
\codem{Integer $\not \sim$ String}
\end{document}

However, this does not compile and complains with the message:

! Improper alphabetic constant.
<to be read again> 
                   \not 
l.622 \codem{Integer $\not \sim$ String}
                                        
? 
! Missing $ inserted.
<inserted text> 
                $
l.622 \codem{Integer $\not \sim$ String}

Why can't I wrap \lstinline here, and how can I achieve a similar abstraction?

    Please always provide a full minimal example that others can copy and test as is, and not sniplets that others have to add code to to be able to test.

    Note that \codem works if you define it as \newcommand{\codem}{\lstinline[mathescape=true]}

  • Awesome, why does it work if you omit the explicit parameter?

  • Verbatim material needs very special care and cannot normally be used in the arguments to macros. Remember that \lstinline{foo} literally writes is arguments, so \lstinline{#1} ought to actually just write #1.
