词汇表：在 tabularx 中扩展失败

词汇表：在 tabularx 中扩展失败

当我第一次在 tabularx 中使用缩写词（词汇表或缩写包）时，它无法展开，甚至会破坏表结构。问题已经提到这里，但没有提供直接的解决方案。

\acf或\acs其他不检查条目首次使用的命令不会出现此问题。但是，这不是解决方案，因为此包的整个想法是自动检查。我正在寻找一种简单的解决方案，不会有太多的处理开销，因为我\ac的文本中有数千个命令。

示例代码：

\documentclass{article}
\usepackage[acronym,shortcuts]{glossaries} 
\usepackage{tabularx}
\newacronym{BI}{BI}{Beacon Interval}

\begin{document}

\begin{tabularx}{\textwidth}{|l|X|}
Parameter & Value \\ \hline
\ac{BI}  & Typical: 0.1 seconds. I heard somebody say, that the sentence ended here, But everyone knows it's goin' still. \\
\end{tabularx}

\bigskip

\begin{tabularx}{\textwidth}{|l|X|}
Parameter & Value \\ \hline
\ac{BI}  & Typical: 0.1 seconds. I heard somebody say, that the sentence ended here, But everyone knows it's goin' still. \\
\end{tabularx}

\end{document}

在此处输入图片描述

\documentclass{article}
\usepackage[acronym,shortcuts]{glossaries} 
\usepackage{tabularx}
\newacronym{BI}{BI}{Beacon Interval}
\makeatletter


\def\foo#1\hbox#2#3!!{%
\def\TX@trial##1{#1\hbox{\let\glsunset\@gobble#2}#3}%
}
\expandafter\foo\TX@trial{#1}!!
\makeatother
\begin{document}


\noindent X \dotfill X

\noindent
\begin{tabularx}{\textwidth}{|l|X|}
Parameter & Value \\ \hline
\ac{BI}  & Typical: 0.1 seconds. I heard somebody say, that the sentence ended here, But everyone knows it's goin' still. \\
\end{tabularx}

\bigskip

\noindent
\begin{tabularx}{\textwidth}{|l|X|}
Parameter & Value \\ \hline
\ac{BI}  & Typical: 0.1 seconds. I heard somebody say, that the sentence ended here, But everyone knows it's goin' still. \\
\end{tabularx}

\noindent X \dotfill X

\end{document}

根据 David 的回答，版本 4.28（2017-01-07）glossaries现在有一个命令\glspatchtabularx可以执行 David 的补丁，而不需要\makeatletter：

\documentclass{article}
\usepackage[acronym,shortcuts]{glossaries}
\usepackage{tabularx}
\newacronym{BI}{BI}{Beacon Interval}

\glspatchtabularx

\begin{document}


\noindent X \dotfill X

\noindent
\begin{tabularx}{\textwidth}{|l|X|}
Parameter & Value \\ \hline
\ac{BI}  & Typical: 0.1 seconds. I heard somebody say, that the
sentence ended here, But everyone knows it's goin' still. \
\end{tabularx}

\bigskip

\noindent
\begin{tabularx}{\textwidth}{|l|X|}
Parameter & Value \\ \hline
\ac{BI}  & Typical: 0.1 seconds. I heard somebody say, that the
sentence ended here, But everyone knows it's goin' still. \
\end{tabularx}

\noindent X \dotfill X

\end{document}

tabularx如果尚未加载，它将不执行任何操作。

我知道这是旧的，并且已经在上游进行了，但我认为我有一个替代解决方案，可能不需要修补tabularx。这个想法是tabularx在排版表格之前进行多次试验，但当它们结束时，在最后一步之前，\@footnotetext让\TX@ftntext，并且此分配可用于识别试验已结束：

\documentclass{article}
\usepackage[acronym,shortcuts]{glossaries}
\usepackage{tabularx}
\newacronym{BI}{BI}{Beacon Interval}
\makeatletter
\renewcommand*{\glsunset}[1]{%
  \ifx\@footnotetext\TX@ftntext
    \gls@ifnotmeasuring
    {%
      \glsdoifexists{#1}%
      {%
        \@glsunset{#1}%
      }%
    }%
  \fi
}
\makeatother
\begin{document}

\noindent X \dotfill X

\noindent
\begin{tabularx}{\textwidth}{|l|X|}
Parameter & Value \\ \hline
\ac{BI}  & Typical: 0.1 seconds. I heard somebody say, that the sentence ended here, But everyone knows it's goin' still. \\
\end{tabularx}

\bigskip

\noindent
\begin{tabularx}{\textwidth}{|l|X|}
Parameter & Value \\ \hline
\ac{BI}  & Typical: 0.1 seconds. I heard somebody say, that the sentence ended here, But everyone knows it's goin' still. \\
\end{tabularx}

\noindent X \dotfill X

\end{document}

当然，这只是“概念证明”，但如果这种检查确实适合情况，那么\gls@ifnotmeasuring基于它提供类似的东西也不会很困难。
