titleps: No \pars allowed in header / footer

[jasperhabicht]

Due to the fact that the relevant commands are not defined as \long, it is not possible to use \par in the headers or footers (not even inside \parboxes or similar), which, however, might be required by the user. At least, I can't see a reason why one would not want to allow this.

For example, the following code will break:

\documentclass{article}
\usepackage{titleps}

\newpagestyle{main}{
    \sethead{}{
        \parbox{\textwidth}{foo \par bar}
    }{}
} 
\pagestyle{main}

\begin{document}
baz
\end{document}

A possible way to circumvent this would be to create a copy of \par:

\documentclass{article}
\usepackage{titleps}
\let\parcopy\par

\newpagestyle{main}{
    \sethead{}{
        \parbox{\textwidth}{foo \parcopy bar}
    }{}
} 
\pagestyle{main}

\begin{document}
baz
\end{document}

I’m closing this issue because it’s an enhancement request. This doesn’t mean it’s rejected, just it’s not listed has an issue.
