我喜欢配置和优化命令，以便获得以下 MWE 的相同输出，而无需使用单独的命令来插入教授的姓名和电子邮件。
\documentclass{report}
\usepackage{xparse}
\usepackage{hyperref}
\newcommand{\profname}[1]{ \newcommand{\profnameloc}{#1} }
\newcommand{\profemail}[1]{ \newcommand{\profemailloc}{#1} }
\NewDocumentCommand\printprofemail{O{}O{}}{
\texttt{\href{mailto:\profemailloc}{\profemailloc}}
}
\NewDocumentCommand{\prof}{mO{}}{\newcommand\profloc{\textbf{\href{mailto:#2}{#1}}}}
\begin{document}
\title{Custom Command}
\prof{Dr. X}[[email protected]]
\profname{Dr. X}
\profemail{[email protected]}
\maketitle
The course is taught by \profloc. His name is \profnameloc and his email is \printprofemail.
\end{document}
我的意思是，我想要的输入：
\documentclass{report}
% [necessary packages and commands]
\begin{document}
\title{Custom Command}
\prof{Dr. X}[[email protected]]
\maketitle
The course is taught by \profloc. His name is \profnameloc and his email is \profemailloc.
\end{document}
我想要的输出是这样的：
The course is taught by (Dr. X)[textbf and hyperlinked]. His name is Dr. X and his email is ([email protected])[texttt and hyperlinked].
我想将教授的电子邮件用作命令中的可选参数，\prof这样如果我仅使用命令，它就不会生成空白超链接\prof{Dr. X}。另外，我想优化\profmailloc以打印\printprofmail与我的 MWE 相同的内容。我的意思是，如果像那样插入电子邮件，则应该显示带有超链接的电子邮件地址，如果没有提供电子邮件，则不应打印任何内容。\prof{Dr. X}[[email protected]]\profemailloc\profemailloc
我想要的输出如果\prof{Dr. X}用来代替：\prof{Dr. X}[[email protected]]
The course is taught by (Dr. X)[textbf but not hyperlinked]. His name is Dr. X and his email is .
还应注意，我当前的 MWE 在命令后产生了空白问题，这些问题也应该得到修复。
