acmart：丑陋的电子邮件地址——如何避免断行？

Question

acmart在我的一些同事的电子邮件地址中创建了非常难看的换行符，我不知道如何解决这个问题，因为诸如\small（减小字体大小）和\hbox（避免换行）之类的操作在这里不起作用。有没有办法让 LaTeX 避免破坏电子邮件地址？

以下是代码示例：

\documentclass[sigconf]{acmart}

\begin{document}

\title{Paper Title}

\author{Author 1}
\email{[email protected]}
\affiliation{Affiliation}

\author{Author 2}
\email{[email protected]}
\affiliation{Affiliation}

\author{Author 3}
\email{[email protected]}
\affiliation{Affiliation}

\author{Author With Long Email 1}
\email{long\_long\_long\[email protected]}
\affiliation{Affiliation}

\author{Author With Long Email 2}
\email{long\_long\_long\[email protected]}
\affiliation{Affiliation}

\maketitle

\end{document}

结果如下：

Answer 1

您可以通过重新定义 \UrlFont 来缩小所有电子邮件的字体。您可以通过重新定义 \UrlBreakPenalty 来避免中断：

\documentclass[sigconf]{acmart}

\begin{document}

\title{Paper Title}

\author{Author 1}
\email{[email protected]}
\affiliation{Affiliation}

\author{Author 2}
\email{[email protected]}
\affiliation{Affiliation}

\author{Author 3}
\email{[email protected]}
\affiliation{Affiliation}

\author{Author With Long Email 1}
\email{long\_long\_long\[email protected]}
\affiliation{Affiliation}

\author{Author With Long Email 2}
\email{long\_long\_long\[email protected]}
\affiliation{Affiliation}

\begingroup
 %\def\UrlFont{\ttfamily\scriptsize} %smaller email
\mathchardef\UrlBreakPenalty=10000
\maketitle

\endgroup
\end{document}
