missing frame title using org beamer export

missing frame title using org beamer export

- issue: org mode beamer export ignored all frame titles

I've tried searching online for couple of hours, but couldn't find a solution. 
Can someone please advise? 

- debug trials and observations

1. The same org file works fine in org-mode version 7.8.08.

However, in org version 8.3.2, the frame titles are missing

2. I tried to add following to the .emacs, but it didn't seem to help.

How did you actually export the file to beamer?  Your LaTeX file seems
to be the result of a LaTeX export, not beamer.  Your org file exports
just fine for me.

Eric,

Thanks for the rely. I used "C-c C-e l p" to export the file. For some
reason "C-c C-e p" no longer works in orgmode v8.3. I'm yet to figure out
how to bind that key directly to pdf output. Is this the same as how you
exported the file?

As you may well be aware, Org changed a lot from 7.x -> 8.x. Have you
been through the various upgrade documents out there? This will be one
of many "surprises" you'll run into if you don't take a look.
- Official upgrade notes: http://orgmode.org/worg/org-8.0.html
- Walkthrough attempt I made:
http://jwhendy.blogspot.com/2013/03/migrating-to-new-org-mode-exporter-org.html
- Beamer for Org 8.x: http://orgmode.org/worg/exporters/beamer/ox-beamer.html

In particular, I'm guessing you don't have the beamer class defined
and aren't aware of =C-c C-e l P= (note capital P), which is the
beamer export function now. It's just sufficient to just define the
class as beamer and export to LaTeX.

Quick answer: go to the second link above and copy that first code
block into your .emacs. Reload your config (or just restart emacs),
and do =C-c C-e l P=. See if that helps.

Hope that gets you pointed in the right direction!


John

You want to do "C-c C-e l P" for beamer export.  Otherwise, you get
LaTeX export.  Your output may look like beamer in that it has used the
LaTeX beamer class (because that's what you told it to do) but it did
not parse the structure of the org file.

If you use "P" instead of "p", ox-beamer will interpret the headlines
properly and you do not need to set LATEX_CLASS.

You may need to add

(require 'ox-beamer)

to your emacs initialisation code.

Thanks, John! I added the beamer definition and used the Upper case P which
almost did the trick, in the sense that all the headings are properly
exported and the frames look as expected. However, the pdf file is missing
the title and author, with only the date showing on the front page.  I
don't see anything obviously wrong in the tex file:

\author{dummy}
\date{\today}
\title{Test Frame title}
\hypersetup{
 pdfauthor={dummy},
 pdftitle={Test Frame title},
 pdfkeywords={},
 pdfsubject={},
 pdfcreator={Emacs 24.3.2 (Org mode 8.3.2)},
 pdflang={English}}
\begin{document}

\maketitle
\begin{frame}{Outline}
\tableofcontents
\end{frame}

Any idea why?

btw. I searched for hours about migrating from v7 to v8 of orgmode, but
didn't come upon your blog. It could've saved me so much headache! Maybe we
should add yours as a link on the worg page? I've avoided the migration as
per the rule "not breaking what works", but it's time to take the plunge
and living through the growing pain :) Thanks for the help!

Thanks Eric. Yes, even though I thought I'd checked all the available
export options, I failed to distinguish the nuances between p and P. Your
initial answer pointed me to the right direction, as I found that pdflatex
on the exported tex would give a different pdf from the export command (C-c
C-e l p). Now one more step closer to the destination, if only I can figure
out how to get the missing title and author in the pdf.

Thanks for all the help!

I just used a minimal config (below), and I get what appears to be the
same! I have an author/date on the front page, though. No idea how to
explain that one... I attached my generated .pdf if that helps. Do you
get any errors during compilation, or perhaps want to see if there's
any output in the *Org LaTeX Errors* (or something like that) buffer?
I wonder if there's a package that you could be missing... though
beamer should be pretty standard/straightforward and with everything
else working, I don't understand why that wouldn't work.

Happy to help. I recall following along from a distance as the mailing
list elisp experts were formalizing everything, seriously having no
idea what was going on. Then it was released and seemed like I might
as well figure out what this was all about. Glad you were able to
migrate and hope there wasn't *too* much pain involved!
