How do I define a beamer overlay specification like beamer:0 as beamerframe key? Something like:


\documentclass{beamer}

\makeatletter
\define@key{beamerframe}{hide}[true]{%

%<--- definition of the beamer:0 switch??
}
\makeatother

\begin{document}

\begin{frame}[hide] %<-- has now overlay specification beamer:0

example text

\end{frame}

\end{document}


Thx in advance!

That's an interesting problem! You could patch the frame environment like this to force the beamer:0 option for the hidden frame.

Caveat: this will throw away any other mode specifications you might pass to the hidden frames.


\documentclass{beamer}

\usepackage{xpatch}

\makeatletter
\newif\ifbeamer@hide
\define@key{beamerframe}{hide}[true]{\beamer@hidetrue}
\BeforeBeginEnvironment{frame}{\beamer@hidefalse}
\xpatchcmd{\beamer@@@@frame}{%
\gdef\beamer@whichframes{#1}%
}{
\ifbeamer@hide
\gdef\beamer@whichframes{beamer:0}%
\else
\gdef\beamer@whichframes{#1}%
\fi
}{}{}
\makeatother

\begin{document}

\begin{frame}
content...
\end{frame}

\begin{frame}[hide] %<-- has now overlay specification beamer:0

example text

\end{frame}

\begin{frame}
content...s
\end{frame}

\end{document}
