I’m currently working on a major new version of the datatool package. This may take a while. Please be patient. (Experimental version available for testing.)

Summary	Last displayed topic subitem has invalid indentation

Description

Greetings,

first of, your package is really great. I use it to write my PhD thesis. I was following your example from page Logical Glossary Divisions (type vs group vs parent) for single hierarchical glossary where the top-level entries represent topics.

Using this style with

set-widest

option using

\GlsXtrLoadResources

, I've found an invalid indentation for the last displayed subitem if the description is a couple of rows long.

I found a solution by changing the style as follows:

    \renewcommand*{\glstopicAssignSubIndent}[1]{%
        \parindent\dimexpr##1\glstopicSubIndent-\glstopicSubIndent\relax
        \glstopicAssignWidest{##1}%
        \hangindent\dimexpr\parindent+\glstopicwidest\relax
    }%
    \renewcommand*{\subglossentry}[3]{%
        \ifnum\glstopic@prevlevel=0\relax\glstopic@prechildren\fi
        \def\glstopic@prevlevel{##1}%
        \glstopicAssignSubIndent{##1}%
        \glstopicSubItem{##1}{##2}{##3}%
        \par%
    }%

Evaluation

Thank you. Appending \par to \subglossentry does indeed fix the problem. Unfortunately removing \par from the start of \glstopicAssignSubIndent upsets the topicmcols style. Leaving \glstopicAssignSubIndent unchanged but adding \par to \subglossentry seems to work for both styles.

Now fixed in v1.46 (allow a few days for the update to reach TeX distributions).
