Hi
I have an R package in org, and would like to tangle it before I submit to
svn.
I commit via a code block:
#+begin_src sh :results output
svn commit -m "edits"
#+end_src
How can I tangle automatically before I commit? I could use batch execution
as described in http://orgmode.org/manual/Batch-execution.html but I think
it would be useless to start another emacs instance? I thought that I could
put it into a header variable to have it evaluated, but I seem to be missing
something:
* test
#+begin_src sh :tangle test.sh :var TANGLED=(org-babel-tangle)
echo TEST''
#+end_src
But I get an error:
Saving file /home/rkrug/tmp/test.org...
Wrote /home/rkrug/tmp/test.org
(No changes need to be saved) [56 times]
cons: Lisp nesting exceeds `max-lisp-eval-depth'
I have the feeling, I am missing something small.
Is there a different way to achieve this?
Cheers,
Rainer

Hi Rainer,
You are very close, the problem is that the code block whose header
argument initiates the tangling should not itself be tangled, otherwise
you will wind up with the infinite recursion error you've noticed.
A setup like the following should work...

** tangle before evaluating a code block
#+begin_src sh :var TANGLED=(org-babel-tangle) :tangle no
wc $TANGLED
#+end_src
#+results:
: 2 2 11 it.sh
#+begin_src sh :tangle it.sh
echo TEST
#+end_src

Works perfectly - I especially like the summary of the tangling via wc
$TANGLED - very nice side effect.
Thanks a lot,
