ID: 162 🔗 Open glossaries 4.45 Felix Kröner 2020-06-14 11:19:55 Using \glspl on acronym while \glsnoexpandfields is active produces wrong output

## Report

In the documentation it states that if one has problems with commands in acronyms one should use the \glsnoexpandfields option.

It solved my problem of using siunitx commands in acronyms but produces an unfortunate side-effect.

Acronym plural usages are not displayed correctly anymore. Instead of the actual acronym being displayed the last defined acronym is displayed instead.

I made a minimal example to reproduce this bug:

\documentclass{scrbook}

\usepackage{glossaries}
\glsnoexpandfields

\newacronym{right}{RIGHT}{right acronym}
\newacronym{wrong}{WRONG}{wrong acronym}

\begin{document}

\glspl{right}. This is \glspl{right}.

\end{document}
It will display the WRONG acronym in the PDF instead of the RIGHT one.

### MWE

\documentclass{scrbook}

\usepackage{glossaries}
\glsnoexpandfields

\newacronym{right}{RIGHT}{right acronym}
\newacronym{wrong}{WRONG}{wrong acronym}

\begin{document}

\glspl{right}. This is \glspl{right}.

\end{document}

## Evaluation

It seems that the original acronym mechanism (which is currently in effect by default) conflicts with \glsnoexpandfields. As a workaround, I recommend switching to the newer acronym mechanism with \setacronymstyle. For example:
\documentclass{scrbook}

\usepackage{glossaries}
\glsnoexpandfields

\setacronymstyle{long-short}

\newacronym{right}{RIGHT}{right acronym}
\newacronym{wrong}{WRONG}{wrong acronym}

\begin{document}

\glspl{right}. This is \glspl{right}.

\end{document}
