[beamer] What is the easiest way to inject latex code between block environments?

[beamer] What is the easiest way to inject latex code between block environments?

[Mikhail Titov]

Hello!

I would like to explicitly define heights for columns that contain blocks to be able to use \vfill [1] in-between blocks. And here comes the problem. I kind of need to inject

#+latex: \vfill

before new block

** block2

but after \end{block} was emitted, not before. Is there an easy way to approach that?

Everything in org-mode gets treated as belonging to the parent
headline. I don't think there's an easy way to do this except by
tweaking the .tex file after export and re-compiling via LaTeX
directly.

I could be wrong, but I believe it's the same principle as why the
answer to these questions is "No":

In other words... everything is always in some headline and what
you're trying to do is escape a headline to enter text in kind of a
"no man's land." Sorry to say, I don't think it's possible.


Best regards,
John

Actually, I was picturing doing this in between /frames/, not blocks.
Since you're in a frame, you can just write the LaTeX syntax directly
inside of your frame headline?

-------------------
* Frame 1
\begin{block}{Block 1}
stuff
\end{block}

\vfill

\begin{block}{Block 2}
more stuff
\end{block}

** Frame 2
------------------

What about that?

That is how I'm proceeding now as I don't have time to hack now:(

I wonder if a special case can be made via some extra property and some changes to orgmode code (or with hooks?). It should be possible as I need just quite specific command and not "arbitrary" text embedded.

That is how beamerposter is organized.

I was trying to escape to orgmode from plain latex not to return that far back ;)

Here is the dirty hack if someone else is also making posters with orgmode &
beamerposter.
Unfortunately I know AWK better than elisp so don't condemn me :-) It does a
perfect job for me. I don't know if can be hooked to pipe through before
writing TeX output.

----8<----------------------------------------------------------------------
------------------->8---------
#!/usr/bin/awk -f
# Post-process orgmode output before final call to pdflatex while using
beamerposter

BEGIN {
    end_block = 0		# 1 if previous line was \end{block}
    columns = 0			# 1 if probably \vbox will be needed, 2 if
it is needed
    RS = "\r\n"			# I'm on Windows
    height = ".98\\textheight"   # FIXME
}

/^\\frametitle{.+}$/ { next}	# frametitle removal from the only frame

/^\\begin{columns}/ { columns = 1 }
/^\\begin{column}/ && columns { columns = 2 }

/^%% .+/ && columns == 2 { print "\\vbox to " height " {%"; columns = 0 } #
we rely on orgmode comments :(

/^\\end{block}$/ { end_block = 1 }

/^\\begin{block}/ && end_block { print "\\vfill"; end_block = 0 }

/^\\end{column}$/ && end_block { print "}%"; columns = 1; end_block = 0 }

{ print }
