Using a footnote in the full name of an acronym

I would like to use a footnote in the full name of an acronym. Here is the minimal (not) working example:

\documentclass{report}
\usepackage{acronym}
\usepackage{footnote}
\begin{document}
\begin{acronym}[ABC]
\acro{ABC}{Alphabet\footnote{this does not work}}
\end{acronym}
The \ac{ABC}\footnote{this works}.
\end{document}


I'm already using the acronym package to link acronyms with publications:

\acro{ABC}{Alphabet\cite{publication2013abc}}


But sometimes there is either no publication or a web site is more appropriate:

\acro{ABC}{Alphabet\footnote{\url{http://website-for-abc.example.org}}}


Any hints?

Edit: Based on the feedback blow, this is another working minimal example:

\documentclass{report}
\usepackage{acronym}
\usepackage{hyperref}

\newcounter{mycount}
\newcounter{savefoot}

\makeatletter
\newcommand\acrofoot[3]{%
\acro{#1}{#2\protect\footnote{#3}\setcounter{mycount}{\value{footnote}}}%
}
\let\acorig\ac
\renewcommand\ac[1]{%
\begingroup%
\setcounter{savefoot}{\value{footnote}}%
\setcounter{footnote}{\value{mycount}}%
\renewcommand\@makefntext[1]{}%
\acorig{#1}%
\setcounter{footnote}{\value{savefoot}}%
\endgroup%
}
\makeatother

\begin{document}
\begin{acronym}[ABC]
\acrofoot{ABC}{Alphabet}{\url{http://abc.example.org}}
\acro{XYZ}{The End}
\acrofoot{Foo}{Bar}{\url{http://foo.example.org}}
\end{acronym}
The \ac{ABC}\footnote{this works}. Also see \ac{XYZ} and \ac{Foo}.
\end{document}


Issue: As you can see in the following picture, the footnote numbering is wrong.

Best regards, Alex

• Welcome to TeX.sx! \protect\footnote might work, \footnote is not robust. By the way: this would work out of the box with the acro package (which also has a built-in mechanism to associate citations with acronyms by the way) – clemens Aug 24 '13 at 11:47
• @Alex I copy you code and run the case with \protect right before \footnote{this does not work} and I get 3 footnotes on the bottom of that page. Is this what you seek? – Jesse Aug 24 '13 at 11:48
• @Jesse: that's to be expected: once in the list, the second time when the acronym is used the first time and the third is the explicit \footnote in the text – clemens Aug 24 '13 at 12:08
• @cgnieder Thanks. Also \protect works. But produces multiple footnotes for the same acronym. – Alex Sep 12 '13 at 7:56
• @Jesse It's a good starting point but indeed not what I'm heading to. – Alex Sep 12 '13 at 7:58

If you don't mind to create a new command \acfoot and use it instead of \ac in these cases, here is a solution:

\documentclass{report}
\usepackage{acronym}
%\usepackage{footnote}

\newcounter{mycount}
\newcounter{savefoot}

\makeatletter
\newcommand\acfoot[1]{%
\begingroup%
\setcounter{savefoot}{\value{footnote}}%
\setcounter{footnote}{\value{mycount}}%
\renewcommand\@makefntext[1]{}%
\ac{#1}%
\setcounter{footnote}{\value{savefoot}}%
\endgroup%
}
\makeatother

\begin{document}
\begin{acronym}[ABC]
\acro{ABC}{Alphabet\protect\footnote{this works}\setcounter{mycount}{\value{footnote}}}
\end{acronym}
The \acfoot{ABC}\footnote{this works, too}.
\end{document}


Output:

Note that you can also define a new command \acrofoot

\newcommand\acrofoot[3]{%
\acro{#1}{#2\protect\footnote{#3}\setcounter{mycount}{\value{footnote}}}%
}


and use it instead of \acro giving the footnote text as the third argument:

\acrofoot{ABC}{Alphabet}{this works}


This solution works better, but has its limitations (for example you can't use numbers in acronym definitions):

\documentclass{report}
\usepackage{acronym}

\newcounter{savefoot}

\makeatletter
\newcommand\acfoot[1]{%
\begingroup%
\setcounter{savefoot}{\value{footnote}}%
\setcounter{footnote}{\value{#1count}}%
\renewcommand\@makefntext[1]{}%
\ac{#1}%
\setcounter{footnote}{\value{savefoot}}%
\endgroup%
}
\makeatother

\newcommand\acrofoot[3]{%
\newcounter{#1count}\acro{#1}{#2\protect\footnote{#3}\setcounter{#1count}{\value{footnote}}}%
}

\begin{document}
\begin{acronym}[ABC]
\acrofoot{ABC}{Alphabet}{\url{http://abc.example.org}}
\acro{XYZ}{The End}
\acrofoot{Foo}{Bar}{\url{http://foo.example.org}}
\end{acronym}

The \acfoot{ABC}\footnote{this works}. Also see \ac{XYZ} and \acfoot{Foo}.
\end{document}


Output:

The trick is to define a new counter for each \acrofoot and use that one for numbering footnotes.

• Good starting point. I updated my question and stated my issue with this solution up there. – Alex Sep 12 '13 at 8:31
• Thanks for the update. Looks good. Unfortunately, I don't really want to know whether I've to use ac or acfoot while writing. So at the end, my goal was to use footnotes in acronyms that do not repeat all the time. I started to play around with the cleverref package a bit - but and at the end I might decide to use normal references again. – Alex Sep 13 '13 at 7:45
