由此question，我如何使用一个命令将其更改为每个单词的首字母大写，并使用另一个命令仅将第一个单词的首字母大写（仍然支持复数形式）形式如下：
\documentclass[a4paper,12pt]{article}
\usepackage{glossaries}
\usepackage{glossary-mcols}
\makeatletter
\let\oldmakefirstuc\makefirstuc
\renewcommand*{\makefirstuc}[1]{%
\def\gls@add@space{}%
\mfu@capitalisewords#1 \@nil\mfu@endcap
}
\def\mfu@capitalisewords#1 #2\mfu@endcap{%
\def\mfu@cap@first{#1}%
\def\mfu@cap@second{#2}%
\gls@add@space
\oldmakefirstuc{#1}%
\def\gls@add@space{ }%
\ifx\mfu@cap@second\@nnil
\let\next@mfu@cap\mfu@noop
\else
\let\next@mfu@cap\mfu@capitalisewords
\fi
\next@mfu@cap#2\mfu@endcap
}
\makeatother
\newglossaryentry{word}{
name = {word},
description = {word description},
plural = {words},
descriptionplural = {words description}
}
\newglossaryentry{good word}{
name = {good word},
description = {good word description},
plural = {good words},
descriptionplural = {good words description},
parent = {word}
}
\makeglossaries
\begin{document}
1. \gls{word}% correct
2. \Gls{word}% correct
3. \glspl{word}% correct
4. \Glspl{word}% correct
5. \glsfirst{word}% correct
6. \Glsfirst{word}% correct
7. \glsplfirst{word}% gives error
8. \Glsplfirst{word}% gives error, doesn't capitalize
1p. \gls{good word}% correct
2p. \Gls{good word}% correct, it capitalizes every words first letter
3p. \glspl{good word}% correct
4p. \Glspl{good word}% correct, it capitalizes every words first letter and does plural
5p. \glsfirst{good word}% correct, it capitalizes every words first letter and does plural
6p. \Glsfirst{good word}% wrong, it should capitalize only first's words first letter.
7p. \glsplfirst{good word}% gives error, doesn't make plural
8p. \Glsplfirst{good word}% gives error, doesn't capitalize first word's first letter and doesn't make plural
\printglossary[style=mcoltreespannav]
\end{document}
结果：
