I have an R package in org, and would like to tangle = it before I submit to svn.

I commit via a code blo= ck:

#+begin_src sh :results output
svn commit = =A0-m "edits"
#+end_src

How can I tangle automatically before I = commit? I could use batch execution as described in=A0=A0http://orgmode.org/manual/Batch-ex= ecution.html but I think it would be useless to start another emacs ins= tance? I thought that I could put it into a header variable to have it eval= uated, but I seem to be missing something:

* test
#+begin_src sh :tangle test.sh :v= ar TANGLED=3D(org-babel-tangle)
=A0 echo TEST''
#+end_src

But I get an error:

Saving file /home/rkrug/tmp/test.org...
Wrote /home/rkrug/tm= p/test.org
(No changes need to be= saved) [56 times]
cons: Lisp nesting exceeds `max-lisp-eval-dept= h'

I have the feeling, I am missing something small.
=

Is there a different way to achieve this?
Cheers,

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...

Works perfectly - I especially like the summary of the tangling via wc $= TANGLED - very nice side effect.

Thanks a lot,

Rainer
