调整首字母缩略词和词汇表-mcol 描述之间的间距

Question

为了节省页面空间，我还使用\usepackage{glossary-mcols}将首字母缩略词打印成两列。同样的空间技巧来自这里 (Nicola 回答)不幸的是，调用后不起作用\setglossarystyle{mcolindex}。如何将相同的距离放入两列缩写中？MWE：

\documentclass[oneside]{scrbook}
\usepackage[english,ngerman]{babel} % Multilingual support -> ctan.org/pkg/babel?lang=en

%TOSET Modify list of (glossar, acronyms, symbols) appearance
\usepackage[acronyms,nopostdot,nonumberlist]{glossaries} % Make custom, multiple, sorted lists (abbreviation, glossary(explaining terms), symbols)
\setacronymstyle{long-short}                % behaviour: first time use long term, then use abbreviation
\newglossary*{mysyms}{Symbolverzeichnis}    % custom glossary, type=mysmys
\makenoidxglossaries                        % initialize, the main(def.) glossary gets dedicated to definitions
\newglossaryentry{potato}{name={potato},plural={potatoes}, description={starchy tuber}}  % From the text reference with \gls{<label>}, for headings \glsentrytext{<label>}
\newglossaryentry{cabbage}{name={cabbage},description={vegetable with thick green or purple leaves}}
\newglossaryentry{ROS_def}{name={ROS},description={Operating system connecting various C++ nodes}}

\newacronym{ac:ros}{ROS}{Roboter Operating System}
\newacronym{ac:svm}{SVM}{support vector machine}
\newacronym{ac:II}{II}{Interconnected Intersection}

\newglossaryentry{R}{type=mysyms,name={R},description={rational number amount}} 

\usepackage{glossary-mcols}
\renewcommand*{\glsmcols}{2}

\begin{document}
    \tableofcontents
        \glstoctrue
        \glsglossarymark{Glossar}               % change header if wanted
        \setglossarystyle{alttree}
        \glssetwidest{cabbage}
        \printnoidxglossary                 % Shortcut to display all glossaries at once 
        \setglossarysection{section}            % get them on one page
        \setglossarystyle{mcolindex}
        \glssetwidest{ROS}
        \printnoidxglossary[type=acronym]
        \printnoidxglossary[type=mysyms]
        \chapter{title}
    Test use: \acrfull{ac:ros} \acrfull{ac:svm} \gls{R} \gls{cabbage} \gls{potato} \gls{ROS_def} \acrfull{ac:II}
\end{document}

Answer 1

该命令\glssetwidest仅适用于alttree样式（参见树状样式）。该glossary-mcols包提供了与 中的样式类似的样式glossary-tree，因此\glssetwidest也可以与mcolalttree样式一起使用，但不能与任何其他样式一起使用。

最简单的解决方案就是替换mcolindex为mcolalttree：

\documentclass[oneside]{scrbook}

\usepackage[acronyms,nopostdot,nonumberlist,toc]{glossaries}

\setacronymstyle{long-short}
\newglossary*{mysyms}{Symbolverzeichnis}

\makenoidxglossaries

\newglossaryentry{potato}{name={potato},plural={potatoes}, description={starchy tuber}}
\newglossaryentry{cabbage}{name={cabbage},description={vegetable with thick green or purple leaves}}
\newglossaryentry{ROS_def}{name={ROS},description={Operating system connecting various C++ nodes}}

\newacronym{ac:ros}{ROS}{Roboter Operating System}
\newacronym{ac:svm}{SVM}{support vector machine}
\newacronym{ac:II}{II}{Interconnected Intersection}

\newglossaryentry{R}{type=mysyms,name={R},description={rational number amount}} 

\usepackage{glossary-mcols}
\renewcommand*{\glsmcols}{2}

\begin{document}
    \tableofcontents

    \glsglossarymark{Glossar}
    \setglossarystyle{alttree}
    \glssetwidest{cabbage}
    \printnoidxglossary
    \setglossarysection{section}
    \setglossarystyle{mcolalttree}
    \glssetwidest{ROS}
    \printnoidxglossary[type=acronym]
    \printnoidxglossary[type=mysyms]

        \chapter{title}
    Test use: \acrfull{ac:ros} \acrfull{ac:svm} \gls{R} \gls{cabbage} \gls{potato} \gls{ROS_def} \acrfull{ac:II}

\end{document}
