# How to print acronym with math environment bold in the index?

I have loaded the acronym package and added an mathenvironment into the options of \acronym. But now the acronym will not be printed bold into the listing of acronyms. How can I print it bold (only in the index not in the body.)?

\documentclass{scrartcl}
\usepackage[footnote, printonlyused]{acronym}

\begin{document}
\section{index}
\begin{acronym}[Abkürzungen]
\acro{PC}{personal computer}
\acro{RAM}{Random Access Memmory}
\acro{HDD}{hard disk drive}
\acro{pi}[$\pi$]{pi}
\end{acronym}

\section{body}
Some hardware components of a \ac{PC} are the \ac{HDD} and the \ac{RAM}.
A thing that is not a component of a \ac{PC} is \ac{pi}.
\end{document}


To get bold math in the labels you can add \boldmath to the \aclabelfont. Just add
\renewcommand*{\aclabelfont}[1]{\textbf{\boldmath\acsfont{#1}}}

You could try using the package 'textgreek', and then use \textpi instead of $\pi$.
• Thank you, but that is not what I am searching for. The $\pi$ was only an example. For any math environment. – Ahrtaler Mar 19 '18 at 10:31
