I'm attempting to generate two distinct glossaries—one for symbols and another for acronyms. However, I'm encountering an issue where the description for symbols doesn't appear on the first use in the text when using '\glsxtrnewsymbol{}'. e.g. $\gls{x}$ only shows x and not position x

I've been stuck on this problem for a couple of hours now, so any help would be greatly appreciated.

My code is based on the excellent answer from Nicola Talbots in this post: Ordered symbols list with units

\documentclass[a4paper,twoside,11pt]{memoir}
\usepackage{siunitx}
\usepackage{xcolor}
\usepackage[colorlinks]{hyperref}
\usepackage[symbols,acronyms,nonumberlist,nogroupskip]{glossaries-extra}
% new keys must be defined before use
\glsaddstoragekey{unit}{}{\glsentryunit}
\glsnoexpandfields
%
\setabbreviationstyle[acronym]{long-short}
%
\glsxtrnewsymbol[description={position},unit={\si{m}}]{x}{\ensuremath{x}}
\glsxtrnewsymbol[description={velocity},unit={\si{\metre\per\second}}]{v}{\ensuremath{v}}
\newacronym{ulm}{ULM}{ultrasound localisation microscopy}
\newacronym{sr}{SR}{super-resolution}
%
\newglossarystyle{symbunitlong}{%
 \setglossarystyle{long3col}% base this style on the list style
 \renewenvironment{theglossary}{% Change the table type --> 3 columns
   \begin{longtable}{lp{\glsdescwidth}>{\centering\arraybackslash}p{2cm}}}%
   {\end{longtable}}%
 %
 \renewcommand*{\glossaryheader}{%  Change the table header
   \bfseries Symbol & \bfseries Description & \bfseries Unit\\\hline
   \endhead}%
 \renewcommand*{\glossentry}[2]{%  Change the displayed items
    \glstarget{##1}{\glossentryname{##1}} %
    & \glossentrydesc{##1}% Description
    & \glsentryunit{##1}  \tabularnewline
 }%
}
%
\makenoidxglossaries
%
% Hyperref setup
\hypersetup{
    colorlinks,
    linkcolor={black!50!black},
    citecolor={black!50!black},
    urlcolor={blue!80!black}
}
%
\begin{document}
\glsaddall
\printunsrtglossary[type=symbols,style=symbunitlong, title=List of Symbols, toctitle=List of Symbols]
\printnoidxglossary[type=acronym, title=List of Acronyms, toctitle=List of Acronyms]
\tableofcontents
%
\chapter{Glossary Test}
First: $\gls{x}$, $\gls{v}$, \gls{ulm}, \gls{sr}\newline
Second: $\gls{x}$, $\gls{v}$, \gls{ulm}, \gls{sr}
\end{document}

  • The glossarystyle is not relevant here, the symbols are not acronyms and so don't default to a special first style. This can be manually set through the first key which can be given in the optional argument to \glsxtrnewsymbol. See this answer. – Dai Bowen Nov 13 '23 at 14:51
  • @Dai Bowen. Thank you for the quick answer. It was my understanding, that the 'first' key would default to the 'description'. But if I understand you correctly, I will have to set the 'first key' manually for each new symbol entry created using '\glsxtrnewsymbol'?

    The problem only exists when using the '{glossaries-extra}' package with '\glsxtrnewsymbol'. The '{glossaries}' package in combination with '\newsymbol' works as expected.

  • I don't understand, \newsymbol is not defined in glossaries or glossaries-extra. \glsxtrnewsymbol is just a wrapper around \newglossaryentry, \newglossaryentry defaults the first key to be the text key which defaults to the name key, only the name key is specified by \glsxtrnewsymbol, acronyms are handled exceptionally in this sense. You can define your own wrapper around \newglossaryentry which parses the symbol and description and passes that to the first key of \newglossaryentry, as the linked answer does with defining a \newsymbol. – Dai Bowen Nov 13 '23 at 16:44
