Hi,

Is it possible to define a custom column like environment?  At the
moment I'm hacking around the need with this:

(add-to-list 'org-beamer-environments-extra
	     '("minipage" "m" "\\begin{minipage}%H" "\\end{minipage}%"))

With the above I can export the following

* 0.1\linewidth						 :B_minipage:
  :PROPERTIES:
  :BEAMER_env: minipage
  :END:
+/cFit/+

to

\begin{minipage}{0.1\linewidth}
\structure{\emph{cFit}}
\end{minipage}%

However within Org, not being able to specify a descriptive headline
sacrifices readability.  It would be great if I could write something
like this:

* Fitting technique					 :B_minipage:
  :PROPERTIES:
  :BEAMER_env: minipage
  :BEAMER_arg: 0.1\linewidth
  :END:
+/cFit/+

I seem to recall this was possible in the past.  Is there any chance to
get something like this going?

Thanks for any thoughts.

Cheers,

The closest would probably be something like

(add-to-list 'org-beamer-environments-extra
             '("minipage"
               "m"
               "\\begin{minipage}%o%a\n\\structure{%h}"
               "\\end{minipage}"))

Which would afford you something like

* slide
** Fitting technique                                            :B_minipage:
  :PROPERTIES:
  :BEAMER_env: minipage
  :BEAMER_OPT: [t]{0.1\linewidth}
  :BEAMER_ACT: <5>
  :END:
  /cFit/

Unfortunately, BEAMER_OPTs are wrapped in square brackets thanks to
org-beamer--normalize-argument, so the above won't actually work (see
org-beamer--format-block).  From the looks of it I'd be willing to call it
a bug, but Nicolas may have had something in mind.

Perhaps these days it would be nice to allow the third element of
org-beamer-environments-extra to be a λ taking either the object or so.
Then again, perhaps this is an overkill and too low-level.

Personally, I'd use a block, e.g.

#+attr_latex: :options [t]{.1\textwidth}
#+begin_minipage
Cfit
#+end_minipage

Well, I would rather keep the formatting in the org file, so no
\structure in the template.  But otherwise your suggestion seems exactly
what I need :).

I was thinking the same.  That's why I felt the need for the old
BEAMER_arg property!

This might be nice, but as you say could be overkill.  Although, there
are a few other cases which is harder to use with the current syntax.
Take minipage as an example, it takes 3 optional arguments[1].
Presently there is no way of dealing with something like that.  Removing
the autowrapping of brackets would allow such cases, but it would
probably break a few Org files in the wild.  From that perspective, a
lambda might be the way to go.

Nice idea.  I have never really explored using blocks (other than for
raw latex), maybe I should ...

Thanks,

IIRC it was a pre-8.0 feature already. In any case, it allows sloppy
writing for options, i.e., with or without square brackets.

More simply, we can also add placeholders in templates, e.g.,

  %R raw action specification
  %O raw options argument

WDYT?

Yes, I think so.

Indeed, that would work well I think.  One can wrap the raw arguments
anyway you wish in the template.

The third argument is hard-coded to 'option in org-beamer--format-block
ATM.

Indeed.  That's the incremental fix.

ox-beamer expects options to be wrapped within square brackets. If they
are not, it does that task. This is a bit drastic, but it works well in
practice.

Done in cf5fd31f0c4f18bd0256157adb98306d53f8a52c.

Works great!  I went with this template:

(add-to-list 'org-beamer-environments-extra
	     '("minipage" "m" "\\begin{minipage}%O{%R}" "\\end{minipage}%"))

For my use case, I rarely use overlay actions, so I repurposed it for
environment arguments.

Thanks a lot!

PS: OT, within beamer I find minipage is easier to manage than columns.
