Citation within caption => avoid italics (biblatex)

Question

In my document, the captions are set in italics. I use a customized biblatex author/year citation style.

If I \cite within a caption, the citation is set in italics as well. How can I avoid that?

Answer 1

biblatex offers the \AtEveryCite hook:

\documentclass{article}

\usepackage[style=authoryear]{biblatex}

\AtEveryCite{\normalfont}

\usepackage{filecontents}

\begin{filecontents}{\jobname.bib}
@misc{A01,
  author = {Author, A.},
  year = {2001},
  title = {Alpha},
}
\end{filecontents}

\addbibresource{\jobname.bib}

\begin{document}

\begin{figure}
\itshape
\centering
\rule{1cm}{1cm}
\caption{A figure \autocite{A01}}
\end{figure}

\printbibliography

\end{document}

Answer 2

The standard latex cite has a formatting hook \@cite@ofmt other packages may offer different interfaces to setting this but something like

\makeatletter
\def\@cite@ofmt#1{\hbox{\reset@font #1}}
\makeatother

probably does what you want.

Answer 3

Unfortunately, David's answer didn't work for me. But based on his solution, I added \reset@font which worked for me:

\DeclareCiteCommand{\cite}[\reset@font\mkbibparens]
{\usebibmacro{prenote}}
{\usebibmacro{citeindex}
\usebibmacro{cite}}
{\multicitedelim}
{\usebibmacro{postnote}}
