Question:

setlist{nosep} not work in the acronym package

Problem:

Since the acronym package is built with the description environment, and the description environment works with Enumitem \setlist{nosep}, why is the Acronym package not affected by this command? I needed to reset the AC@deflist environment to have a similar effect, which is a much more complex solution than a simple command. Is it possible to configure Acronym to react to the \setlist{nosep} command?

\renewenvironment{AC@deflist}[1]{

\ifAC@nolist%

\else%

\raggedright\begin{list}{}{

\settowidth{\labelwidth}{\AC@makelabel{\aclabelfont{#1}}}%

\setlength{\leftmargin}{\labelwidth}%

\addtolength{\leftmargin}{\labelsep}%

\setlength{\itemsep}{0pt}

\setlength{\parsep}{0pt}

\setlength{\parskip}{0pt}

\renewcommand{\makelabel}{\AC@makelabel}

}

\fi

}{

\ifAC@nolist%

\else%

\end{list}%

\fi

}

Solution:

It is possible to redefine the AC@deflist environment to use description instead of list with the code below. This way the \setlist{nosep} command will also be applied to the acronym list.

\documentclass{article}

\usepackage{acronym}

\usepackage{enumitem}

\setlist{nosep}

\makeatletter

\renewenvironment{AC@deflist}[1]%

{\begin{description}[leftmargin=!, labelwidth=3cm, labelsep=0pt, itemindent=0pt]}%

{\end{description}}

\makeatother

\begin{document}

\begin{acronym}
