Glossarysstyle "altlist" look using package "glossaries-extra" instead of "glossaries"

Question

In a previously asked question How to make the term "page" show in the Glossary list?, I was advised to use the glossaries-extra package instead of the glossaries package.

In the glossaries package I used \setglossarystyle{altlist} in order to make my list contain:

1. the abbreviation
2. what the abbreviations stands for
3. a description of the abbreviation

It can look like:

when using the acronym entry

\newacronym
[description = {Immediate instability point: sometimes used in the literature as a synonym to SLL}]
{iip}{IIP}{Immediate instability point}

but after starting to use the glossaries-extra package it looks like this instead:

Why is that, and what can be done about it?

Thank you in advance!

Answer 1

The glossaries-extra package uses a different abbreviation mechanism to the base glossaries package, which allows greater flexibility and multiple abbreviation styles. Abbreviations are defined using \newabbreviation but to allow for easy conversion from the base glossaries, \newacronym is redefined in terms of \newabbreviation. The style for abbreviations defined using \newacronym should now be set using \setabbreviationstyle[acronym]{style-name}. For example:

\setabbreviationstyle[acronym]{long-short-desc}
\newacronym
[description = {Immediate instability point: sometimes used in the literature as a synonym to SLL}]
{iip}{IIP}{Immediate instability point}
