Re: [babel] Conditional tangling possible

Hi Rainer,

The easiest way to do this should be,

--8<---------------cut here---------------start------------->8---
** pulling information from tags                                       :blue:

#+begin_src R :var color=(car (org-get-tags-at (point))) :tangle example.R
  color
#+end_src

#+results:
: blue
--8<---------------cut here---------------end--------------->8---

this will tangle to

--8<---------------cut here---------------start------------->8---
color <- "blue"
color
--8<---------------cut here---------------end--------------->8---

Cheers -- Eric
