[O] :exports not being respected

[Vikas Rawal]

I have a with just the following header, and it is not respecting :exports in 
my R source blocks. The pdf file created has source code as well as the results.

What is wrong? Has the syntax changed again? I have not done anything with 
org-export-babel-evaluate.

I am on Org-mode version 8.3.5 (release_8.3.5-1026-g096f42)

[O] How to pass an array of integers to a C code block with :var?

[Alef Farah]

Hi,

I am trying to use babel's :var to pass an array of integers to a C code
block. I can do it like this:

#+begin_src C :var arr='(1 2) :includes 
printf("%d %d\n", arr[0], arr[1]);
#+end_src

However, I wish to assign the output of another code block to the
variable, like this:

#+name: input
#+begin_src sh
seq 2
#+end_src

#+begin_src C :var arr=input :includes 
printf("%d %d\n", arr[0], arr[1]);
#+end_src

But this way, "arr" is evaluated as a string. I tried formatting the
output of the input code block as '(1 2), but it is still evaluated as a
string.

Is there any way to do this without manually grabbing the list from the
results of the input code block and pasting it in the C block?

No. If you have a Fencepost login you can access the list.

Org keeps a public list on Worg, though.

[O] Controlling exported Beamer quote indentation / width

[Jarmo Hurri]

Greetings.

Currently in my Beamer slides quotes in second-level lists get cropped
outside the view window. Attached is a demo of this. How do I control
the indentation and/or the width of the quote?

As an interesting side effect, the attached file takes ages (like 30
seconds of processor time) to be exported and opened as a PDF, while
much larger files get processed in just a few seconds. No idea why this
is the case.
