词汇表中带有回忆录类的条目中有额外的“@”

以下memoir类源文件在使用pdflatex和处理时makeindex，使用memoir类basic.gst词汇表样式文件，会生成缺少第 3 个条目（关于“从一个集合到另一个集合的功能”）的词汇表：

\documentclass{memoir}

\usepackage{amsmath}

\makeglossary[glossary]

\begin{document}

The empty set is denoted by $\emptyset$.%
\glossary[glossary]{$\emptyset$}{empty set}

The set of all subsets of a set $X$ is denoted by $\mathcal{P}(X)$.%
\glossary[glossary]{$\mathcal{P}(X)$}{power set of set}

\newpage

For sets $X$ and $Y$, the notation $f \colon X \to Y$ means that $f$ is a functions from $X$ to $Y$.%
\glossary[glossary]{$f \colon X \to Y$}{function from one set to another}

\printglossary[glossary]

\end{document}

生成的文件glossary.glo有第三个也是最后一个条目：

\glossaryentry{$f \penalty \@M \mskip 2mu\mathpunct {}\nonscript \mkern -\thinmuskip {:}\mskip 6muplus1mu\relax X \to Y$@ {\memgloterm{$f \penalty \@M \mskip 2mu\mathpunct {}\nonscript \mkern -\thinmuskip {:}\mskip 6muplus1mu\relax X \to Y$}}{\memglodesc{function from one set to another}} {\memgloref{}}|memjustarg}{2}

但是，生成的文件glossary.gls中不包含相应的条目。

日志文件glossary.glg包括：

...Scanning input file glossary.glo....
!! Input index error (file = glossary.glo, line = 3):
   -- Extra `@' at position 106 of first argument.
done (2 entries accepted, 1 rejected).
Sorting entries....done (2 comparisons).....

该如何解决？

答案1

这是 定义中的一个错误\@@glossary，它\@sanitize在吸收了其参数后就会这样做，从而违背了其目的。

只要您不在\glossary另一个命令的参数中使用，您就可以使用不扩展命令的不同定义：

\documentclass{memoir}

\usepackage{xparse}

\makeglossary[glossary]

\makeatletter
\RenewDocumentCommand{\glossary}{O{\jobname}d()vv}{%
  \@bsphack
  \@ifundefined{#1memglofile}{\@esphack}
   {%
    \def\memglofile{#1}%
    \begingroup
    \IfNoValueTF{#2}
      {\@wrglom@m{#3}{#3}{#4}}
      {\@wrglom@m{#2}{#3}{#4}}
   }%
}
\makeatother

\begin{document}

The empty set is denoted by $\emptyset$.%
\glossary[glossary]{$\emptyset$}{empty set}

The set of all subsets of a set $X$ is denoted by $\mathcal{P}(X)$.%
\glossary[glossary]{$\mathcal{P}(X)$}{power set of set}

\newpage

For sets $X$ and $Y$, the notation $f \colon X \to Y$ means that 
$f$ is a functions from $X$ to $Y$.%
\glossary[glossary]{$f \colon X \to Y$}{function from one set to another}

\printglossary[glossary]

\end{document}

替代解决方案：重新定义\@wrglom@m

\documentclass{memoir}
\makeglossary[glossary]

\makeatletter
\renewcommand{\@wrglom@m}[3]{%
  \protected@write\@auxout{}{%
    \string\@@wrglom@m
      {\memglofile}%
      {\unexpanded{\unexpanded{#1}}}%
      {\unexpanded{\unexpanded{#2}}}%
      {\unexpanded{\unexpanded{#3}}}%
      {\@nameuse{memglsnx\memglofile}}{\@nameuse{memglsn\memglofile}}%
  }%
  \endgroup
  \@esphack
}
\makeatother

\begin{document}

The empty set is denoted by $\emptyset$.%
\glossary[glossary]{$\emptyset$}{empty set}

The set of all subsets of a set $X$ is denoted by $\mathcal{P}(X)$.%
\glossary[glossary]{$\mathcal{P}(X)$}{power set of set}

\newpage

For sets $X$ and $Y$, the notation $f \colon X \to Y$ means that 
$f$ is a functions from $X$ to $Y$.%
\glossary[glossary]{$f \colon X \to Y$}{function from one set to another}

\printglossary[glossary]

\end{document}

答案2

您只需要在定义中\protect使用 s 的有问题的宏。@

\documentclass{memoir}

\usepackage{amsmath}

\makeglossary[glossary]

\begin{document}

The empty set is denoted by $\emptyset$.%
\glossary[glossary]{$\emptyset$}{empty set}

The set of all subsets of a set $X$ is denoted by $\mathcal{P}(X)$.%
\glossary[glossary]{$\mathcal{P}(X)$}{power set of set}

\newpage

For sets $X$ and $Y$, the notation $f \colon X \to Y$ means that $f$ is a functions from $X$ to $Y$.%
\glossary[glossary]{$f \protect\colon X \protect\to Y$}{function from one set to another}

\printglossary[glossary]

\end{document}

带保护的词汇表

答案3

Herb Schulz 向我指出，潜在的问题在于这\colon是一个关系命令。

一个简单的解决方法，仍然给实际结肠左侧留出比\colon定义更小的空间

\newcommand{\from}{\mathpunct{:}}

然后使用，例如：

$f \from X \to Y$

在正文和相应的项目中均有体现\glossary。

从数学风格的角度来看，我不确定哪一个能在实际冒号周围产生更令人满意的间距 - \newcommand{\from}{\mathpunct{:}}或者\newcommand{\from}{\protect\colon}。（有什么想法吗？）
