Org-beamer problems

Org-beamer problems

[Bill Moran]

I've been trying to follow the various tutorials on the web 
to do beamer in org-mode. I've used beamer, latex and emacs 
for many years but am finding that none of the examples on 
the web work totally s intended in my attempts to use
org-mode with beamer. 

I have copied verbatim several examples such as from here:

http://orgmode.org/worg/org-tutorials/org-beamer/tutorial.html#sec-4_1

When I run  them I get the following problems - plus others 
I will go into later if necessary:

1. The title page does not have a title - just the date. 
When I check the latex file created from the org file I 
notice that a \maketitle command occurs outside a frame environment 
- whereas in beamer I normally use \titlepage inside a frame
environment to create the titlepage. 

2. \alert command does not work - even with the additions to .emacs 
suggested here:
 http://www.mail-archive.com/emacs-orgmode@gnu.org/msg21507.html
(And there are no errors in running the .emacs file) 
Always the @ symbol appears in the latex created from org as @. 

I wonder whether there is some configuration I am missing. 
Other aspects of the slides are normal - bullets and 
frametitles specifically.

What version of org-mode are your running? What version of emacs? If
you haven't done so already, try upgrading to the latest version of
org and seeing if that solves the problem.

=M-x org-version RET=
=M-x emacs-version RET=

See the latest development version of org:

My immediate response would be to ask why you aren't using \maketitle
given that the command is beamer-aware?  That is, \maketitle will create
a title page whose format is defined by the beamer theme you have
selected.  Otherwise, you could always customise
=org-export-latex-title-command= to nothing and use direct latex code to
do what you want:

--8<---------------cut here---------------start------------->8---
#+begin_latex
\begin{frame} \titlepage \end{frame}
#+end_latex
--8<---------------cut here---------------end--------------->8---

I've not tried this.

Can you tell us exactly what you have done to customise the relevant
variables and where you have done these customisations?  Difficult to
help without this information unfortunately.  While we're at it, org and
emacs version information is also helpful.

Thanks for all of your responses and for taking the time to help me. I'll try to
answer your questions. As far as possible I  use the "stock" ubuntu (maverick -
10.10) repositories for emacs and its associated software. So I'm using emacs
23.1.1 and org-mode 6.36c. The version of beamer I'm using, as described in the
repositories, is latex-beamer 3.07-2ubuntu1. I am aware  that there are more
recent versions available  - particularly of org-mode - but was trying to keep
things simple. 

Let me also say that my aim was to arrive at an understanding of  how to use
org-mode for slide creation - since I do a lot of that - rather than to compose
a specific set of slides. I realise that I could use direct latex code to solve
the problems but that wasn't the point of the exercise. 

I've read more since I sent the email and now realise that the issues I brought
up have been discussed earlier and where I can I've tried to use the proposed
solutions. In particular I have this in my .emacs:

 
(setq org-emphasis-alist (quote (("*" bold "<b>" "</b>") 
      				 ("/" italic "<i>" "</i>")
      				 ("_" underline "<span style=\"text-decoration:underline;\">" "</span>")
      				 ("=" org-code "<code>" "</code>" verbatim)
      				 ("~" org-verbatim "<code>" "</code>" verbatim)
      				 ("+" (:strike-through t) "<del>" "</del>")
      				 ("@" org-warning "<b>" "</b>")))
      org-export-latex-emphasis-alist (quote 
      				       (("*" "\\textbf{%s}" nil)
      					("/" "\\emph{%s}" nil) 
      					("_" "\\underline{%s}" nil)
      					("+" "\\texttt{%s}" nil)
      					("=" "\\verb=%s=" nil)
      					("~" "\\verb~%s~" t)
      					("@" "\\alert{%s}" nil)))
      )

from a solution to the @ problem proposed by Eric somewhere. And I understand
that I can use \maketitle normally to produce a title page in beamer - just
tried on a hand-crafted (in emacs)  latex-beamer file using my set up.  

To keep this email as brief as possible, let's take this snippet (verbatim) of
an  example from Eric:

* Methodology

** A simple slide
This slide consists of some text with a number of bullet points:
- the first, very @important@, point!
- the previous point shows the use of the special markup which
  translates to the Beamer specific /alert/ command for highlighting
  text.
The above list could be numbered or any other type of list and may
include sub-lists.
---------------------------end----------------------------------------

When I do "C-c C-e p" to create the pdf file I get 3 slides. The first is a
title page but has no title - only the date. The second is an outline (toc)
slide as expected and the third is again as expected except that @important@ is
not rendered as \alert{important}.

Re: Org-beamer problems

[Henri-Paul Indiogine]

Greetings!

I am also having difficulties running Beamer from org-mode.   I am
running a fully updated Ubuntu with snapshot emacs and a daily updated
git version of org-mode.

I am not able to get blocks, lists, and colums to work.  I have a
feeling from Googling quite a bit that the problem is due to some
interaction between my org-mode header and .emacs.

Unfortunately, the org-mode manual does not state how to configure
.emacs for Beamer export.  There must be something going on with the
levels of headers and the B_Block directive.  

Basically, I can not get the example to work.

Here is the relevant part of my .emacs

-------------------------------------------------
(setq org-export-latex-classes 
      '(("article" "\\documentclass[11pt]{article}"
         ("\\section{%s}" . "\\section*{%s}")
	 ("\\subsection{%s}" . "\\subsection*{%s}")
	 ("\\subsubsection{%s}" . "\\subsubsection*{%s}")
	 ("\\paragraph{%s}" . "\\paragraph*{%s}")
	 ("\\subparagraph{%s}" . "\\subparagraph*{%s}"))

	("beamer" "\\documentclass[bigger]{beamer}
                   \\usepackage{verbatim}
                   \\definecolor{verylightgray}{rgb}{0.93,0.93,1.0}
                   \\mode<beamer>{\\usetheme{Madrid}}
                   \\mode<handout>{\\usecolortheme[rgb={0.5,0.5,0.5}]{structure}
                   \\usepackage{pgfpages}}
                   \\usepackage[absolute,overlay]{textpos}
                   \\setlength{\\TPHorizModule}{1mm}
                   \\setlength{\\TPVertModule}{1mm}"
         ("\\section{%s}" . "\\section*{%s}")
         ("\\begin{frame}[fragile]\\frametitle{%s}" "\\end{frame}"
          "\\begin{frame}[fragile]\\frametitle{%s}" "\\end{frame}"))
--------------------------------------------------------

The header is the same as from the example.

Thanks,
Henri-Paul

Hi Henri-Paul,

I'm running =org-version= 7.3 (release_7.3.89.g97f4c.dirty)

I don't have anything in my .emacs about the beamer latex class - it just
works.  The only =org-export-latex-classes= statements that I have are with
some latex classes that I have made myself.

What does your .tex output look like?

Upgraded to the latest .deb version of org-mode - 7.4 - and that solved the
title problem - but not the @ problem.

You do not need to configure anything for beamer support with recent
(since 7.0 but even earlier) versions of org.

This is not needed and will in fact cause problems.  The tutorial
example on Worg should work out of the box except for the already
discussed problems with the @ syntax for alerts.

Org-beamer problems

[Bill Moran]

I have installed the latest (git) version of org-mode and have stripped out all
customizations from  I think. I've copied Eric's two column example from here

http://orgmode.org/worg/org-tutorials/org-beamer/tutorial.html

with the headers given there. And I can't get either blocks or columns to work.
There is no block or column command in the latex produced from the org file. 

I guess it's something to do with the value of the variable 

org-export-latex-classes 

but have been unable to find a statement of what that should be. I think I've
undone all customizations of that  variable from earlier attempts but can't be
sure. 

Thanks for your help.

Bill

I have no idea what is going on but I can confirm that something is
missing.  If I start emacs with -Q, execute the following

#+begin_src emacs-lisp
(add-to-list 'load-path "~/git/org-mode/lisp")
(require 'org-install)
(require 'org-latex)
#+end_src

visit the small beamer test file I sent to the list earlier today and
export to latex, I get only the title page and the empty outline.
Nothing else.

If I start up with my full initialisation, everything works just fine.

I've gone through my initialisation by eye and cannot see anything that

I don't think so.  Although I do customise mine, if I include this in
the above test (-Q start), it makes no difference.  I do not change the
"beamer" entry in any case.

I will play around later tonight and will get back to you then.

Hi Eric

I've just tried with the totally minimal customization you suggest below -
and your  two-column slide which I had already set up
( I haven't had time to go to the website yet and download the one you
suggest). Now columns are working  in some fashion
but apparently not blocks.  The two column slide is spread across two slides
each with one column.

I'll work on it some more later - and test your slide on the website.

So something else in my emacs customization - which is pretty extensive but
(since yesterday)
has nothing other than vanilla for org-mode (just paths and your
org-emphasis-alist ) -
is causing a problem in producing the columns. I'll go through this later
too and see if I can find it.

Thanks

Bill

Playing with the following org file:

--8<---------------cut here---------------end--------------->8---

everything works just fine with "emacs -Q" and the emacs lisp code I
gave in the previous email.  The change is a subtle one: I got rid of
the "#+STARTUP: oddonly" customisation in the org file and indented all
the headlines to use both odd and even levels.

I have no idea why the =oddonly= setting causes problems.  However, I do
note that the documentation for =org-odd-levels-only= only mentions
=odd= and =oddeven= for possible values of =#+STARTUP= so maybe my use
of =oddonly= is the issue?  I'll leave this to others to comment on
hopefully.

Hi Eric

I've just done this - emacs -Q, the minimal .emacs from your previous email,
and your  piece of org/beamer.

It  creates blocks, examples and columns - so it works as it should. Next -
but not immediately - is to find out why my usual .emacs doesn't work.

Thanks for all of your help in sorting this out. I look forward to using
org-mode to create slides.

I'll report if I find the problem.

Bill
