我喜歡配置和優化命令，以便獲得以下 MWE 的相同輸出，而無需使用單獨的命令插入教授的姓名和電子郵件。
\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，我想要的輸入：
\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}
我想要的輸出是這樣的：
The course is taught by (Dr. X)[textbf and hyperlinked]. His name is Dr. X and his email is ([email protected])[texttt and hyperlinked].
我想使用教授電子郵件作為命令中的可選參數，\prof這樣如果我只使用命令，它就不應該產生空白超連結\prof{Dr. X}。另外，我喜歡優化\profmailloc列印，使其與我的 MWE 相同\printprofmail。我的意思是，如果像這樣插入電子郵件，那麼應該顯示帶有超連結的電子郵件地址，如果沒有給出電子郵件，則不應列印任何內容。\prof{Dr. X}[[email protected]]\profemailloc\profemailloc
我想要的輸出 if\prof{Dr. X}使用而不是：\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 .
還應該注意的是，我目前的 MWE 在命令後產生空格問題，這些問題也應該得到解決。
