[bug] beamer export envargs for column not working properly

[bug] beamer export envargs for column not working properly

[Eric S Fraga]

Hi,

I am trying to create a beamer slide which has two columns.  The second
column should only appear after a while (the 6th uncovering operation).
In latex, I would do:

: \begin{column}<6->{0.4\textwidth}

say.  In org, I would expect to be able to get this latex code generated
by the following:

--8<---------------cut here---------------start------------->8---
***** column heading			      :BMCOL:B_block:
      :PROPERTIES:
      :BEAMER_col: 0.4
      :BEAMER_envargs: c<6->
      :BEAMER_extra: 
      :BEAMER_env: block
      :END:
--8<---------------cut here---------------end--------------->8---

according to the info documentation (Beamer class export).

However, this does not work: the "c<6->" is placed verbatim in
the \begin{block} that comes after the \begin{column}.  Furthermore, if
I ask for the heading to be ignored (instead of defining a block), the
envargs are lost completely!

Thanks,
eric

Hi Eric,

could you make me a slightly more complete example, with your beamer  
setup?
So a full test file that will show this behavior?

Thanks.

Sure.  The attached example has a single slide.  With the file as it is,
i.e. with an ignored heading for the second column of the slide, the
slide overlay directive is thrown away upon export.  

If you change the headline of the second column to be a block heading
(C-c C-b b), on export the overlay directive is not thrown away but it
is attached to the block and not the column.  This is okay in that
accomplishes the same purpose (in this case but not others); however, it
does not match the documentation in any case.

Thanks,
eric

Hi Eric,

thank you for the more detailed example.  I think this should
be fixed now.  The documentation was not really wrong, because
it only mentioned c[...] and not c<...>.  But I agree that
there is not reason to no allow this.

Thanks, Eric, for your continuous effort to help improving Org!
We would not have BEAMER export without you, I think - a fact
that is now mentioned in the manual, in the acknowledgement
section.	

Cheers

- Carsten

Very true!  But thanks for extending this.  I'll try it out later when I
get back to my slides.

You're very welcome but my contributions are minimal in comparison!  And
it's easy to contribute from such a good starting point.
