Problems with fragile frames in Beamer
2
I found a nice solution of re-using titles of beamer frames here by defining:
newenvironment{slide}[0]{
begin{frame}ifx insertsubsection empty
frametitle{insertsection} else
frametitle{insertsubsection}framesubtitle{insertsection} fi
}{end{frame}}
With this definition I can't use lstlistings because the frame has to be fragile.
So, I've tried to change the definition to:
newenvironment{slide}[0]{
begin{frame}[fragile]ifx insertsubsection empty
frametitle{insertsection} else
frametitle{insertsubsection}framesubtitle{insertsection} fi
}{end{frame}}
But it don't work with the error:
File ended while scanning use of next.
Here is my little example:
documentclass{beamer}
usepackage{listings}
newenvironment{slide}[0]{
begin{frame}[fragile]ifx insertsubsection empty
frametitle{insertsection} else
frametitle{insertsubsection}framesubtitle{insertsection} fi
}{end{frame}}
begin{document}
begin{slide}
begin{lstlisting}[caption={A simple listing.}, label={lst:simple}]
public static void main(String args) {
// hello world
}
end{lstlisting}
end{slide}
end{document}
Thank you for your help!

Hiding the frame environment behind a new name is a very bad idea. Why not redefine the frametitle to show the section and subsection? Should all frames have the section and subsection as farmetitle, or only this frame?

@samcarter: I agree that with beamer, redefining title may be easier, but could you explain why using another name is a bad idea? The only reason I can think about is that using other names make parsing and scripting more complicated.

@sztruks Oh, there are a couple of reasons - in no particular order: It often reduces the functionality, because redefinitions often don't think about optional arguments, e.g.begin{frame}<beamer:1-4|handout:0>[plain]{frametitle}{subtitle}. -- If the appearance of the frametitle should be changed the corresponding template should be adjusted instead of working around like this -- In my opinion it obscures the code with no gain -- It makes the code less portable between presentations and more difficult to create MWE.

You need to use the environment option. As verbatim environments are a bit special concerning environment endings it has to be known how the environment is called.
Btw: I replaced your low-level ifx tests with etoolbox commands to ensure they even work when empty is defined ;)
documentclass{beamer}
usepackage{listings}
newenvironment{slide}{
begin{frame}[fragile,environment=slide]
ifdefvoid{insertsubsection}{%
frametitle{insertsection}}{%
frametitle{insertsubsection}framesubtitle{insertsection}}}
{end{frame}}
begin{document}
begin{slide}
begin{lstlisting}[caption={A simple listing.}, label={lst:simple}]
public static void main(String args) {
// hello world
}
end{lstlisting}
end{slide}
end{document}
