Vertical space between glossary entries

Question

Is there a way to increase (well add, right now there seems to be hardly any) the vertical space between glossary entries without making a custom style, if so how? Had a quick run through the user manual but did not find anything in between all entries, not just for groups or changing the heading or...

I am using

\printglossary[type=person, nonumberlist=false, style=index] 

for very long entries with long multiline descriptions. So if there is a solution that depends on something the would not work with multiple columns, rely on adding a paragraph after the entry or something like that -- all would be fine.

Answer 1

Use \renewcommand*{\glspostdescription}{<vertical space>} to add vertical space between the items listed.

\documentclass{article}

\usepackage{glossaries}

\makeglossaries

\renewcommand*{\glspostdescription}{\medskip} % add space after each item

\newglossaryentry{Blackbox1}
{
    name=Blackbox models 1,
    sort=blackbox,
    description={--- In system identification, the term \emph{blackbox} modelling refers to the process of modelling a system through non-parametric techniques.}
}

\newglossaryentry{Blackbox2}
{
    name=Blackbox models 2,
    sort=blackbox,
    description={--- In system identification, the term \emph{blackbox} modelling refers to the process of modelling a system through non-parametric techniques.}
}

\newglossaryentry{Blackbox3}
{
    name=Blackbox models 3,
    sort=blackbox,
    description={--- In system identification, the term \emph{blackbox} modelling refers to the process of modelling a system through non-parametric techniques.}
}
