Beamer presentation in the document

Beamer presentation in the document

[Sébastien Vauban]

Hi,

Got a few questions about a beamer presentation that is a subtree in the
document.

Let's take this example:

** Amounts

*** Data

    Here, I study different cases, with the data provided by the client.

*** Assumptions

    Having made the following assumptions:
    - first
    - second
    - third

*** Results

    I get this resulting table:

    #+ATTR_LaTeX: align=lr
    | Rate (%) |  Interests |
    |----------+------------|
    |     3.50 | 2564935.21 |

    |     5.00 | 3664193.15 |
    |     5.50 | 4030612.46 |
    #+TBLFM: $2=(73283863*$1)/100;%.2f

* Presentation
  :PROPERTIES:
  :TITLE: Beamer slides
  :LaTeX_CLASS: beamer
  :LaTeX_CLASS_OPTIONS: [presentation,t]

  :COLUMNS: %40ITEM %10BEAMER_env(Env) %10BEAMER_envargs(Env Args) %4BEAMER_col(Col) %8BEAMER_extra(Extra)
  :END:

** Amounts

  - Here is the table:

    #+ATTR_LaTeX: align=lr
    | Rate (%) |  Interests |
    |----------+------------|
    |     3.50 | 2564935.21 |
    |     4.00 | 2931354.52 |
    |     4.50 | 3297773.83 |
    |     5.00 | 3664193.15 |
    |     5.50 | 4030612.46 |
    #+TBLFM: $2=(73283863*$1)/100;%.2f

    See document for full analysis.
--8<---------------cut here---------------end--------------->8---

Questions are:

1. How could I use the same table in the slides as in the document, without
   copy/pasting it?

   Is there, maybe, some Babel black magic at hand?  Export/import?

2. How can I use a title, for the slides, different from the heading
   `Presentation'?

   You can see that my `TITLE' property gets ignored.

3. How can I easily switch between exporting:
   - the document, or
   - the slides?

   I guess I must use include/exclude tags?  Right?

   Anything standardized in that direction?

Best regards,
  Seb

PS- Carsten, have hyper-ultra-mega nice holidays!

The following babel solution should work.  It uses a code block to copy
the contents of the table into the presentation on export.  I think I'll
add the "echo" code block in the below example to the library of babel,
so in the future this should work w/o having to include the code block
in the file.

I was sure you had "black magic" to provide us with. Thanks a lot (once

1. On the echo functionality itself, everything is perfect, but for the
   horizontal lines that are not echo'ed.

2. For Babel, more generally, some remarks that I have for a while, but always
   forget to report (as you're allowed to consider them as "details" ;-)):

   - Babel does not find the tables if the `#+tblname: XXX' instruction is not
     located at column 0 -- annoying for me, as I try to perfectly align all
     the text and source code based on `org-indent'-like functionality;

   - the `results' block is not "naturally" aligned either;

   - less a detail than the 2 above: would it be possible to leave some text
     between the `call' and the `results': in this example, so that the
     `align' statement does not move after the table whenever we `C-c C-c' the
     block for executing the `echo'?

I think so as well. This is a must for enabling us to insert slides into a
document. And something nobody else (PowerPoint, even plain LaTeX?) can do
(AFAIK).

To exclude the slides is done via:

--8<---------------cut here---------------start------------->8---
#+EXPORT_EXCLUDE_TAGS: presentation


* Introduction

* Chapter 1

* Chapter 2

* Conclusion

* Presentation                                                  :presentation:
  :PROPERTIES:
  :LaTeX_CLASS: beamer

  :COLUMNS: %40ITEM %10BEAMER_env(Env) %10BEAMER_envargs(Env Args) %4BEAMER_col(Col) %8BEAMER_extra(Extra)
  :END:

** Slide 1

** Slide 2

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

"To only get the slides" is equivalent to "to exclude the document"; so, one
solution can be to tag all the chapters in my document, and exclude such tags.

hlines are preservable with the :hlines header argument, see the example
below [1].

Were working on integrating the babel documentation in the org-mode
documentation which should really help in terms of making these more
exotic header arguments accessible/discoverable to users.

Good catch, this has been fixed.

Again, thanks for pointing this out.  This has been fixed for results
which already have an indented

  #+results:

line, for the first time a block is run the results will not be indented
currently, although it would probably be worthwhile to default to
indenting the results to the same level as the code block -- I'll add
this as a TODO.

See the example below [1], is it sufficient to squeeze the #+results
line in between the #+attr_latex line and the table?  If not I'll update
the results handling so that we allow preservation of comment lines
between #+results and it's contents.

OK. Thanks.

Now that's we (/ I) can't live anymore without both of them, it'd clearly be
great having a unified documentation.

Simply great. It caused me some minutes to understand why tables were reported
as not found...

That's already great.

Less important, even if nice when it will be there.

Why only preserving comment lines?  Why couldn't we imagine having the code
somewhere and the results much farther?  Even twice the results -- that'd be a
work around for the echo command.

This should be possible now -- I've done a fairly thorough examination
of the Org-babel code and tried to ensure that *everything* works well
with indentation.

It's very possible I've introduced some bugs in the process, please let
me know if you find any.

This is another feature which may not be well enough advertised.

If a code block is named, then we already allow the block and it's
results to live arbitrarily far apart as long as they're in the same
buffer e.g. [1].

That allows for separation of code and results which I think is an
important feature.

What I don't want to separate by too far is the

  #+results: name

line, and the actual results.  Mainly because the purpose of that
#+results: line is to identify the results.  Given that I think allowing
a continuous string of comment lines between a #+results and it's target
e.g.

--8<---------------cut here---------------start------------->8---
#+results: time
# some comment about the time
: Thu Jun 10 14:48:09 2010
: Thu Jun 10 14:47:58 2010
--8<---------------cut here---------------end--------------->8---

is acceptable, but I think allowing arbitrary distance between them
subverts the purpose of the #+results: line.

I hope that sheds some light on this issue.

Please let me know if you agree/disagree of if you do think comment
separation like the above does make sense, in which case I'll add it to
the queue.

Cheers -- Eric

This does not work properly, in fact. It is also related to my question #2:

Doing the above way takes "Presentation  :presentation:" as title (tag
included).

OK. I did not take enough attention when reading. I thought you only preserved
comment lines between the call and the results. No, you were speaking of
comment lines between the #+results line and the actual result contents.

The above makes perfectly sense to me. If I were you, I would never allow
separation between the #+results line and the actual results, for the same
reason as you invoked: the #+results line is for identifying the actual
results.

Though, allowing comment lines is a great feature (even, if I don't use it yet).

I just updated Org this morning, and I can't remove the echo snippet from the
Org buffer. Do I have to do something extra regarding the lob?

Two extra comments:

- Why don't you make `:hlines yes' the default value?  I guess, if we wanna
  copy a table, it's "as it is" by default, so with hlines and all...

- Not really a detail: the "echo" is perfect, but for the decimal precision.
  The `%.2f' spec is not preserved, as you can see above. That'd be great if
  it could be.

Best regards and *many thanks* as always,
  Seb

Does someone have a solution for being able to have another TITLE than the
headings for the presentation part?

Note -- This could be extended for AUTHOR, and other meta-properties of the
        document.

The only thing I can suggest is not so elegant solution of inserting
directly the appropriate latex commands (\title, \author)...

Do the properties

EXPORT_TITLE
EXPORT_AUTHOR
EXPORT_DATE

work for this?
