¿Cómo nombrar varias etiquetas simultáneamente?

Question

En este ejemplo, los uso \cref{first,second}y clevereflos etiqueto correctamente:

\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}

Pero, si uso \nameref{first,second}, entonces solo me da ??en lugar de First and Second.

¿Cómo puedo usarlo \namerefcon varias etiquetas como \cref?

Answer 1

Puede utilizar el siguiente código. Tenga en cuenta que ese useres su nombre para mostrar actual; probablemente debería reemplazar el userprefijo en el código con algo que sea más probable que sea único para asegurarse de no entrar en conflicto con otro código no relacionado que pueda existir usando el mismo prefijo.

\begin{document}

References:
\begin{itemize}
\item With one reference and hyperlink: \nameRefs{first} (we'll disable
  hyperlinks from now on, because their default appearance is hideous and they
  don't behave very well across line breaks);
\item With one reference: \nameRefs*{first};
\item With two references: \nameRefs*{first, second};
\item With three references: \nameRefs*{first, second, third};
\item With four references: \nameRefs*{first, second, third, fourth};
\item Capitalized variant: \NameRefs*{first, second, third, fourth};
\item etc.
