\input{…} is ignored with beamer option ignorenonframetext

Question

I'm using beamer to create my slides and wanted to use beamerarticle to create written paper which is not just printed slides 3 on 1 page.

The option ignorenonframetext for the beamer class forces it to ignore any text but \section{} etc. that is not inside a frame environment. This is intended for interaction with the beamerarticle class to edit all information (frames and additional text) at the same place.

Unfortunately the \input{} command is ignored as well, making it impossible to organize my document in the usual way, i.e. one file for any section for example.

Is there any additional option to activate this kind of "infrastructure" command in beamer?

Example

\documentclass[ignorenonframetext]{beamer}
%\documentclass{scrartcl} \usepackage{beamerarticle}

\usetheme{Goettingen}
\usecolortheme{crane}
\title{Test slides}
\author{Christoph Juengling}

\begin{document}
\maketitle
\begin{frame}
  \titlepage
\end{frame}

\input{sec-one}

This is explaning text at the end of the first section.

\input{sec-two}

\end{document}

In this example, using the beamerarticle class all looks fine, but with the beamer class activated with the specified option, nothing but the title frame will be created. The two additional files do contain valid LaTeX code with frames!

Answer 1

In the documentation of beamer on pages 211 and 212 you find the explanation and also an example. To use input or inlcude with the option ignorenonframetext you must enable ignorenonframetext for this part. \mode* is equivalent to the option ignorenonframetext. You can enable it with \mode<all> or \mode<presentation>. Here an example:

\RequirePackage{filecontents}
\begin{filecontents}{sec-one.tex}
\begin{frame}
\frametitle{sec one}
  foo
\end{frame}
\end{filecontents}
\begin{filecontents}{sec-two.tex}
\begin{frame}
\frametitle{sec two}
  foo
\end{frame}
\end{filecontents}

\documentclass[ignorenonframetext]{beamer}
%\documentclass{scrartcl} \usepackage{beamerarticle}

\usetheme{Goettingen}
\usecolortheme{crane}
\title{Test slides}
\author{Christoph Juengling}

\begin{document}
\maketitle

\begin{frame}
  \titlepage
\end{frame}
\mode<all>
\input{sec-one}
\mode*
This is explaning text at the end of the first section.

\input{sec-two}

\end{document}
