\includeonlyframes and pdftitle

Question

When I use beamer with \includeonlyframes{someframe}, the resulting PDF has the same pdftitle as the overall document. Is there any way to set the pdftitle to the title of the someframe, the only frame I am including?

\documentclass{beamer}
\includeonlyframes{frametwo}
\title{Document title}
\begin{document}%
\begin{frame}[label=frameone]{Frame one}
Spam
\end{frame}
\begin{frame}[label=frametwo]{Frame two}
Eggs
\end{frame}
\end{document}

Running pdflatex mini results in a PDF with title Document title. Is there any way to get the title of the only frame that is compiled?

Answer 1

You can set the pdftitle yourself using \hypersetup{pdftitle=<title>} after you disable the use of it by beamer using the usepdftitle=false option.

\documentclass[usepdftitle=false]{beamer}
\includeonlyframes{frametwo}
\hypersetup{pdftitle=frametwo}
\title{Document title}
\begin{document}%
\begin{frame}[label=frameone]{Frame one}
Spam
\end{frame}
\begin{frame}[label=frametwo]{Frame two}
Eggs
\end{frame}
\end{document}

If you need this often and/or like to avoid having the name written twice you could redefine \includeonlyframes to do this automatically:

\documentclass[usepdftitle=false]{beamer}

\makeatletter
\renewcommand\includeonlyframes[1]{%
    \hypersetup{pdftitle={#1}}%
    \def\beamer@framerestriction{#1,}%
}
\makeatother

However, I didn't found a way to switch usepdftitle off automatically if \includeonlyframes is used. With it off you won't get any title for all frames.
