Wie werden mehrere Labels gleichzeitig mit Namen referenziert?

Question

In diesem Beispiel verwende ich sie \cref{first,second}und cleverefbeschrifte sie korrekt:

\documentclass[10pt,a5paper]{memoir}
\usepackage[brazil]{babel}
\usepackage{hyperref}
\usepackage{cleveref}

\begin{document}

\namecref{first,second}

\chapter{First}
\label{first}

\chapter{Second}
\label{second}

\end{document}

Wenn ich jedoch verwende \nameref{first,second}, erhalte ich nur ??anstelle von First and Second.

Wie kann ich \namerefmehrere Etiketten als verwenden \cref?

Answer 1

Sie können den folgenden Code verwenden. Beachten Sie, dass dies userIhr aktueller Anzeigename ist. Sie sollten das userPräfix im Code wahrscheinlich durch etwas ersetzen, das eindeutiger ist, um sicherzustellen, dass es nicht zu Konflikten mit anderem, nicht verwandten Code kommt, der möglicherweise dasselbe Präfix verwendet.

References:

  don't behave very well across line breaks);
