acronymsglossaries
I have a question. I want to use SI unit X in my acronym definitions. For example:
\newacronym{M}{\si{\Molar}}{molar}
Sadly this doesn't work. Is there a way to do use SI units in the acronym definition? I know about the possibility to use \newglossaryentry, but I want to have all my acronyms in one list.
When I remove all the \si parts, it works. But I'd like to have the spacing right.
As I already said in the comments: acro provides the foreign key for cases like this. Nonetheless: here is a way to achieve what you want with acronym. The usage is similar to acronym's \acroextra. The code below defines a command \acroforeign{<foreign long form>} that is to be placed inside the second mandatory argument of \acro:
\documentclass{article}
\usepackage{acronym}
% provides \AtBeginEnvironment, \patchcmd and \csdef:
\usepackage{etoolbox}
\makeatletter
\newcommand{\acroforeign}[1]{}
% patch the environment to print the foreign definition:
\AtBeginEnvironment{acronym}{%
\def\acroforeign#1{ (#1)}%
}
% patch the acronym definition to safe the foreign definition:
\expandafter\patchcmd\csname AC@\AC@prefix{}@acro\endcsname
{\begingroup}
{\begingroup\def\acroforeign##1{\csdef{ac@#1@foreign}{##1, }}}
{}
{\fail}
% % renew the first output to include the foreign definition if given:
\renewcommand*{\@acf}[2][\AC@linebreakpenalty]{%
\ifAC@footnote
\acsfont{\csname ac@#2@foreign\endcsname\AC@acs{#2}}%
\footnote{\AC@placelabel{#2}\AC@acl{#2}{}}%
\else
\acffont{%
\AC@placelabel{#2}\AC@acl{#2}%
\nolinebreak[#1] %
\acfsfont{(\acsfont{\csname ac@#2@foreign\endcsname\AC@acs{#2}})}%
}%
\fi
\ifAC@starred\else\AC@logged{#2}\fi
}
\makeatother
\begin{document}
First: \ac{ECU}, \ac{BW}
Subsequent: \ac{ECU}, \ac{BW}
List:
\begin{acronym}[ECU]
\acro{ECU}{Steuerger\"at\acroforeign{Electronic Control Unit}}
\acro{BW}{Baden-W\"urttemberg}
\end{acronym}
\end{document}
The problem is caused by the fact that internally the footnote is using \glslabel to reference the entry but the definition of this command has changed by the time the footnote is processed. The simplest thing to do is to modify the style to ensure the label is expanded first, as in the modified example below:
\documentclass{scrreprt}
\usepackage{ragged2e}
\usepackage[table, dvipsnames]{xcolor}
\usepackage[backref=page,plainpages=false,pdfpagelabels,colorlinks]{hyperref}
\usepackage[style=listgroup,acronym,toc,hyperfirst]{glossaries}
\setglossarystyle{long}
\newacronymstyle{ex-footnote}%

\GlsUseAcrEntryDispStyle{footnote}%
}%
{%
\GlsUseAcrStyleDefs{footnote}%
\renewcommand*{\genacrfullformat}[2]{%
\firstacronymfont{\glsentryshort{##1}}##2%
\expandafter\footnote\expandafter{\expandafter\glsentrylong\expandafter{##1}}%
}%
\renewcommand*{\Genacrfullformat}[2]{%
\firstacronymfont{\Glsentryshort{##1}}##2%
\expandafter\footnote\expandafter{\expandafter\glsentrylong\expandafter{##1}}%
}%
\renewcommand*{\genplacrfullformat}[2]{%
\firstacronymfont{\glsentryshortpl{##1}}##2%
\expandafter\footnote\expandafter{\expandafter\glsentrylongpl\expandafter{##1}}%
}%
\renewcommand*{\Genplacrfullformat}[2]{%
\firstacronymfont{\Glsentryshortpl{##1}}##2%
\expandafter\footnote\expandafter{\expandafter\glsentrylongpl\expandafter{##1}}%
}%
}
\setacronymstyle{ex-footnote}

(It would help if you provide a minimal working example (MWE) that people can work with.)
The problem is caused by the default expansion that's performed when the entry is defined. This can be fixed by using
\glsnoexpandfieldsto switch off the expansion:Alternative, protect the fragile commands:
