引用（重复标记）以避免重复文本

在我正在撰写的文档中，我有一个类似于此的列表：

\begin{itemize}
    \item \emph{c} before \emph{e} or \emph{i} is pronounced as in \emph{church}
    \item \emph{g} before \emph{e} or \emph{i} is pronounced as in \emph{gin}
\end{itemize}

当然，有大量的重复文本。是否可以用一个字符“”来代替它，该字符居中并采用合适的宽度？

最终结果应如下所示：

c before e or i is pronounced as in church
g             ”               as in gin

答案1

你可以用包来得到类似的东西eqparbox（两种变体）：

\documentclass{article}
\usepackage{eqparbox} 

\begin{document}

\begin{itemize}
\item \emph{c} \eqmakebox[NR]{before \emph{e} or \emph{i} is pronounced as in} \emph{church}
\item \emph{g} \eqmakebox[NR]{ — } \emph{gin}
\item \emph{g} \eqmakebox[NR][s]{ — — — } \emph{gin}
\end{itemize}

\end{document}

答案2

您可以测量文本的宽度，并将其用于仅包含引号的相同宽度的框。

\documentclass{article}
\begin{document}
\setbox0\hbox{before \emph{e} or \emph{i} is pronounced}
\begin{itemize}
    \item \emph{c} before \emph{e} or \emph{i} is pronounced as in \emph{church}
    \item \emph{g} \makebox[\the\wd0][c]{"}  as in \emph{gin}
\end{itemize}
\end{document}

在此处输入图片描述

并且您可以使用宏来缩写它。

\documentclass{article}
\setbox0\hbox{before \emph{e} or \emph{i} is pronounced}
\newcommand{\pft}{\makebox[\the\wd0][c]{"}\ }
\begin{document}
\begin{itemize}
    \item \emph{c} before \emph{e} or \emph{i} is pronounced as in \emph{church}
    \item \emph{g} \pft  as in \emph{gin}
\end{itemize}
\end{document}

答案3

您的建议是//或<<，每两个字符。为什么不是三个字符？

\newcommand{\QW}{before \emph{e} or \emph{i} is pronounced as in }
% ...
\item \emph{c} \QW \emph{church}

选择适合您的任何两个字母的宏名称。

当我写上述答案时，提问者“澄清”了这个问题。结果，澄清使这个对原始问题的回答无效。

编辑

这是对您修改后的问题的另一个（冗长的）回答。使用tabular。

% repeatprob.tex SE 513244  avoid repeating text

\documentclass{article}

\begin{document}
\newcommand*{\MB}{$\bullet$}
\newcommand*{\RP}{------ '' ------}
% for even less text
\newcommand*{\Entry}[2]{\MB & \emph{#1} & \RP \emph{#2} \\}

\setlength{\tabcolsep}{1pt}
\begin{tabular}{cccl}
$\bullet$ & \emph{c} & before \emph{e} or \emph{i} is pronounced as in & \emph{church} \\
\MB & \emph{g} & '' & \emph{gin} \\
\MB & \emph{g} & \RP & \emph{gin} \\
\Entry{g}{gin}
\end{tabular}

\end{document}
