# Formatting list of acronyms

I am using the acro package to define and reference acronyms in a document. This has been working fine and the list prints. However, everything in the list is double spaced and I would like to have acronyms with very long long-names be only single spaced. A sample of code I am working with is

\documentclass[12pt]{report}
\usepackage[letterpaper,verbose,tmargin=1.25in,bmargin=1.25in,lmargin=1.4in,rmargin=1.15in]{geometry}
\usepackage{setspace}

\usepackage{titlesec}
\titlespacing{\chapter}{0pt}{-18pt}{\baselineskip}
\titleformat{\chapter}{\centering\normalsize}{\thechapter.}{1em}{}

\usepackage{acro}
\acsetup{list-style=tabular, only-used=false, sort=false}
\DeclareInstance{acro-title}{empty}{sectioning}{name-format =}

\DeclareAcronym{VLA}{
short = VLA,
long  = This acronym is so long that the long from requires two lines to display it
}

\DeclareAcronym{EVIL}{
short = EVIL,
long  = Every Villain is Lemons
}

\begin{document}
\doublespacing

\chapter*{NOMENCLATURE}

\pagestyle{plain}

\pagebreak{}

\end{document}


And the output looks like this

I would like the VLA acronym to be single spaced, but have double spacing between the VLA and EVIL acronyms.

Best!

• Welcome to TeX.SX!! Please give a full minimal working example. Currently we have to guess what packages etc you are using and this makes it really hard to help you. A MWE should start with a \documentclass command, have a minimal preamble and then \begin{document}...\end{document}. The code should compile and be as small as possible to demonstrate your problem. Cutting your code down to a MWE may well reveal what your problem actually is. In any case, it is really difficult to help you without more information. – Andrew Nov 3 '16 at 23:08

\DeclareAcroListStyle{tabular}{table}{
table = tabular ,
before = \singlespacing\renewcommand\arraystretch{1.655}
}


\singlespacing also adds an additional vertical skip of \baselineskip which you might want to remove:

\DeclareAcroListStyle{tabular}{table}{
table = tabular ,
before = \singlespacing\vspace*{-\baselineskip}\renewcommand\arraystretch{1.655}
}


1.655 is the stretch value setspace uses for double spacing when the font size is 12pt.

• This works perfectly. Thank you so much. The only question I have is how did you decide that 1.655 was the 'correct' value of the array stretch? – kwodzicki Nov 4 '16 at 11:58
• I looked it up in setspace.sty. It's what the package uses for double spacing for 12pt. – clemens Nov 4 '16 at 12:40

One crude solution is to remove the \doublespacing command and add a \newline to every long definition as follows:

\documentclass[12pt]{report}
\usepackage[letterpaper,verbose,tmargin=1.25in,bmargin=1.25in,lmargin=1.4in,rmargin=1.15in]{geometry}
\usepackage{setspace}

\usepackage{titlesec}
\titlespacing{\chapter}{0pt}{-18pt}{\baselineskip}
\titleformat{\chapter}{\centering\normalsize}{\thechapter.}{1em}{}

\usepackage{acro}
\acsetup{list-style=tabular, only-used=false, sort=false}
\DeclareInstance{acro-title}{empty}{sectioning}{name-format =}

\DeclareAcronym{VLA}{
short = VLA,
long  = This acronym is so long that the long from requires two lines to display it\newline
}

\DeclareAcronym{EVIL}{
short = EVIL,
long  = Every Villain is Lemons\newline
}

\begin{document}

\chapter*{NOMENCLATURE}

\pagestyle{plain}
