如何正确设置大写章节标题？

Question

sectsty我曾经使用包将章节标题设置为大写\MakeUppercase。但这在章节标题中使用引用时会出现问题。那么如何正确做到这一点呢？

这是一个简单的例子：

\documentclass{article}

\usepackage{nameref}
\usepackage{sectsty}
\sectionfont{\MakeUppercase}

\begin{document}

\begin{description}
  \item [Keyword\label{key}] This is the description text.
\end{description}

\section{Here it does not work: \nameref{key}}

Here it works: \nameref{key}.

\end{document}

Answer 1

您需要一个可扩展的版本\nameref。

\documentclass{article}

\usepackage{nameref}
\usepackage{sectsty}
\sectionfont{\MakeUppercase}

\makeatletter
\newcommand\enameref[1]{%
  \expandafter\ifx\csname r@#1\endcsname\relax
  ??\typeout{^^JLaTeX Warning: Reference #1 undefined on input line \the\inputlineno}%
  \else
    \expandafter\expandafter\expandafter\@thirdoffive\csname r@#1\endcsname
  \fi
}
\makeatother

\begin{document}

\begin{description}
  \item [Keyword\label{key}] This is the description text.
\end{description}

\section{Here it does not work: \enameref{key}}

Here it works: \nameref{key}.

\end{document}
