词汇表-额外丢弃期限和缩写长格式

Question

当使用以下期限discardperiod的功能时glossaries-extra，如果使用明确的长格式，则会被不适当地丢弃：

\documentclass{article}

\usepackage[
  abbreviations,
  shortcuts=abbr,
]{glossaries-extra}

\glssetcategoryattribute{abbreviation}{discardperiod}{true}
\glssetcategoryattribute{abbreviation}{retainfirstuseperiod}{true}

\newabbreviation{dr}{Dr.}{Doctor}

\begin{document}

% This is OK.
\ab{dr}. \ab{dr}.

% This is still OK.
\as{dr}.

% This period gets unduly discarded.
\al{dr}.

\end{document}

有人碰巧知道正确处理此案的方法吗？

Answer 1

我想我可以想出一些合理的办法，即使这个办法比我希望的要棘手。

\documentclass{article}

\usepackage[
  abbreviations,
  shortcuts=abbr,
]{glossaries-extra}

\glssetcategoryattribute{abbreviation}{discardperiod}{true}
\glssetcategoryattribute{abbreviation}{retainfirstuseperiod}{true}

\newtoggle{glsenddot}
\NewDocumentCommand{\glsdot}{}{\global\toggletrue{glsenddot}.\@}
\makeatletter
\renewcommand*{\glsxtrifperiod}[1]{%
  \iftoggle{glsenddot}
    {%
      \global\togglefalse{glsenddot}%
      \new@ifnextchar.{\@firstoftwo{#1}}%
    }
    {\@secondoftwo{#1}}%
}
\makeatother
\preto\glsxtrpostlink{\global\togglefalse{glsenddot}}

\newabbreviation{dr}{Dr\glsdot}{Doctor}
\newabbreviation{abc}{ABC}{Aaaa Bbbb Cccc}

\begin{document}

% This is OK.
\ab{dr}.  \ab{abc}. \ab{abc}. \ab{dr}.

% This is still OK.
\as{dr}.

% This period is now in place.
\al{dr}.

\ab{abc}.

\end{document}
