Paragraph style glossaries acronym list

Question

So I have started developing an acronym style that is paragraph based.

I have a general paragraph working except for two problems"

• one, I haven't figured out how to remove the list separation punctuation from the last element
• and two, if I use my glossary counts attribute on a custom field that I called "category", I don't get a list... at all:

Here's a MWE that doesn't produce a list at all.

\documentclass{article}

\usepackage{textgreek}

    \usepackage[savewrites=true,nogroupskip,style=tree]{glossaries-extra}

    \newcommand{\acrinverse}[1]{{\acrshort{#1}}\xspace{\acrlong{#1}}}

    \newglossary[alg]{acronym}{acr}{acn}{List of Acronyms}

\makeindex
\makeglossaries

    \glsenableentrycount % enable \cgls, \cglspl, \cGls, \cGlspl
    \glssetcategoryattribute{acronym}{entrycount}{1}

    % Not using \newabbreviation so redefine \cglsformat
    % to just check for the long field.

Answer 1

For your custom glossary style, the problem is essentially displaying a list with a separator between each item but not before or after the first or last entry. For this we can use the same method described in Iteration Tips and Tricks. Like this:

\newglossarystyle{paragraphAcronymList}{%
    \setglossarystyle{tree}% base this style on the list style
    \def\entrysep{\def\entrysep{; }}%
    \renewenvironment{theglossary}%
    {\setlength{\parindent}{0pt}%
     \setlength{\parskip}{0pt plus 0.3pt}}%
    {.}%
    \renewcommand*{\glossentry}[2]{%
        \entrysep\glstarget{##1}{\glossentryname{##1}}:~\space\glossentrydesc{##1}\glspostdescription}%
}

The entry counting problem is probably best posted as a separate question.
