beamer export: misplaced \end{frame} with \lecture structure

[Gürtler, Martin]

Hi,

I was trying to use the \lecture command in latex to structure my lecture.

As org-modeis not able to convert , say, first-level headlines into
\lecture statements, I placed the \lecture statement directly before
first level headlines. Unfortunately,in the resulting tex document, the
\end{frame} statement appears only after the \lecture statement. So, in
the resulting pdf, the information about a new lecture (which is created
from a \AtBeginLecture macro) appears as part of the last slide of the
previous lecture and not as a new frame.

1. What can I do in the org mode file in order to enforce ending the
  frame before the \lecture statement.
2. Would anybody be willing to implement \lecture and maybe \part in the
  exporter?

Thanks a lot

Not ideal but you could do something like this:

@@beamer:\end{frame}\lecture{This week's lecture}{week2}\begin{frame}Today's lecture: \insertlecture@@

maybe using it by defining a macro (untested)

#+macro: lecture @@beamer:\end{frame}\lecture{$1}{$2}\begin{frame}Today's lecture: \insertlecture@@

and then use as

{{{lecture(This week's lecture,week2)}}}

Can you play with changing the org-latex-class beamer entry?  Probably not, I guess, as both part and lecture need two arguments...
