Change order of acronyms text in two languages acronyms with glossaries-extra

Question

I'm using glossaries-extra for spanish and english acronims, and works well for my. I followed this posts:

Using the glossaries package for English acronyms in German documents

But I want to change the order in that the acronyms is showed in the list in the case that user1 is defined.

Im using this

\documentclass{article}
\usepackage{lmodern}
\usepackage[utf8]{inputenc}         

\usepackage[acronym, nomain, nonumberlist, toc]{glossaries-extra}
\setabbreviationstyle[acronym]{long-short-user}

\renewcommand{\glsxtrpostdescacronym}{%
 \ifglshasfield{\glsxtruserfield}{\glscurrententrylabel}%
 { (\textit{\glscurrentfieldvalue})}%
 {}%
}
\makeglossaries

\newacronym[user1=Signal to Noise Ratio]{snr}{SNR}{relación señal a ruido}
\newacronym{utn}{UTN}{Universidad Tecnológica Nacional}

\begin{document}    

Primer uso de \gls{snr}. Segundo uso de \gls{snr}.

Primer uso de \gls{utn}. Segundo uso de \gls{utn}.

\printglossaries

\end{document}

and I get:

But I want:

In summary I want to show

short user1 (long)

if user1 is defined, else I want to show only

short long

Can somebody help me?

Best Regards,

Answer 1

There are two approaches that I can think of. The first is to define a custom style that's modified to check for the user1 field. For example:

\documentclass{article}
\usepackage{lmodern}
\usepackage[utf8]{inputenc}         

\usepackage[acronym, nomain, nonumberlist, toc]{glossaries-extra}
\setabbreviationstyle[acronym]{long-short-user}

\makeglossaries

\newacronym[user1=Signal to Noise Ratio]{snr}{SNR}{relación señal a ruido}
\newacronym{utn}{UTN}{Universidad Tecnológica Nacional}

\newglossarystyle{bilinguallist}{%
  \setglossarystyle{list}% base it on the list style
  \renewcommand*{\glossentry}[2]{%
    \item[\glsentryitem{##1}%
          \glstarget{##1}{\glossentryname{##1}}]
      \ifglshasfield{\glsxtruserfield}{##1}%
      {\textit{\glscurrentfieldvalue} (\glossentrydesc{##1})}%
      {\glossentrydesc{##1}}%
      \glspostdescription\space ##2}%
}
\setglossarystyle{bilinguallist}% set this new style

\begin{document}

Primer uso de \gls{snr}. Segundo uso de \gls{snr}.

Primer uso de \gls{utn}. Segundo uso de \gls{utn}.

\printglossaries

\end{document}

The second method modifies \glossentrydesc which is used in all the predefined glossary styles when displaying the description.

With the base glossaries package, this command just checks if the entry has been defined and displays the description. The glossaries-extra package redefines this command to set the current abbreviation style and check for the attributes glossdescfont and glossdesc before displaying the description.

If you're not interested in using the glossdescfont and glossdesc attributes, you could just redefine \glossentrydesc like this:

\documentclass{article}
\usepackage{lmodern}
\usepackage[utf8]{inputenc}         

\usepackage[acronym, nomain, nonumberlist, toc]{glossaries-extra}
\setabbreviationstyle[acronym]{long-short-user}

\makeglossaries

\newacronym[user1=Signal to Noise Ratio]{snr}{SNR}{relación señal a ruido}
\newacronym{utn}{UTN}{Universidad Tecnológica Nacional}

\renewcommand{\glossentrydesc}[1]{%
 \glsdoifexistsorwarn{#1}%
 {%
   \glssetabbrvfmt{\glscategory{#1}}%
   \ifglshasfield{\glsxtruserfield}{#1}%
   {\textit{\glscurrentfieldvalue} (\glsentrydesc{#1})}%
   {\glsentrydesc{#1}}%
 }%
}

\begin{document}

Primer uso de \gls{snr}. Segundo uso de \gls{snr}.

Primer uso de \gls{utn}. Segundo uso de \gls{utn}.

\printglossaries

\end{document}

The result is the same as before.
