Re: beamer columns

[Darlan Cavalcante Moreira <darcamo@gmail.com>]

Hello Carsten and all,

I have sent a suggestion in the beamer thread about using comments for columns,
but I didn't receive my own message from the mailing list (as usual). Therefore
I'm assuming no one else has received it and I'm going to repeat it here (sorry
if this is a duplicate).


The idea is using special comments to represent columns when exporting to beamer
(and maybe other formats). For instance, considering the frames are in the
third-level headings, a presentation could be like

,----
| * This is a Section
| *** This is a Subsection
| ***** This is the frame title
|       Frame content
| 
| ***** This is the frame title of another frame
| #+\{0.4
|       - This is an item
|       - This is an item too
| #+\\0.6
|       - Another item
|       - Another one
|       - One more item
| #+\}
`----

The comment "#+\{" indicates the beginning of a columns environment (maybe only
"#+{" is better) in addition to the first column. The number "0.4" indicates the
width of the first column (0.4\textwidth). The comment "#+\\0.6" creates another
column and the comment "#+\}" closes the columns environment.

I'm not saying this is the best way, but it has the advantage of being similar
to what we do in beamer (but simpler IMHO) and it would export without errors
for other formats. Maybe it is better to also implement it for standard latex
using minipages or something similar and to HTML, but if this is not desired
then the closing comment could be optional (the columns environment would then
end when the current slide ends).

With some org functions to mark, swap, etc., columns it could be easy to
reorganize the columns if desired.

Also, It would be nice if the width could be optional, i.e., if there are
columns whose widths were not specified then org could sum the widths that were
specified and distribute the remaining among the columns whose widths were not
specified. For instance, in a frame with 3 columns one could specify the width
of the first column as 0.4 and leave the others unspecified. Org should then
choose a width of 0.3 for each of the remaining two columns.


At last, thank you for the effort to implement native beamer support in org.
