Hi Rainer,
I've just pushed up a fix for the org-babel-post-tangle-hook.
With a minimal org-babel configuration, if I open the following file.
--8<---------------cut here---------------start------------->8---
** tangle R and load
:PROPERTIES:
:tangle: to-load.r
:END:
evaluate this
#+begin_src emacs-lisp :results silent :tangle no
(add-hook 'org-babel-post-tangle-hook
(lambda () (message "I'm in %s" (buffer-file-name))))
#+end_src
then tangle
#+begin_src R :comments yes
x <- 8
#+end_src
#+begin_src R
y <- 9
#+end_src
--8<---------------cut here---------------end--------------->8---
evaluate the emacs-lisp code block to initialize my post-tangle-hook,
and then tangle the very same file, I see the following in my messages
buffer, indicating that the correct file is now being visited.
--8<---------------cut here---------------start------------->8---
Wrote /home/eschulte/Desktop/to-load.r [2 times]
tangled 2 code blocks
I'm in /home/eschulte/Desktop/to-load.r
--8<---------------cut here---------------end--------------->8---
Hopefully this will now work for you as well.
Thanks -- Eric
