Is it possible to add a function to org-ctrl-c-ctrl-c-hook= without patching ob-core.el? If I just add something like

(add-hook 'org-ctrl-c-ctrl-c-hook 'org-babel-stop-if-file-c= ollision)

in my .emacs I notice that my addition gets overwritten late= r via the autoloads (I think) that are defined in ob-core.el..

Header arg values can be elisp calls. You can use `make-temp-file'= ;.

So every time this block is executed, a new file is created and the
file link is added to the results.

#+BEGIN_SRC R :results output append :file (make-temp-file "temp"= )
cat(date(),"\n")
#+END_SRC

#+RESULTS:
[[file:/var/folders/kb/2hchpbyj7lb6z76l0q73w_fh0000gn/T/temp302IjV]]
[[file:/var/folders/kb/2hchpbyj7lb6z76l0q73w_fh0000gn/T/temp3028Lu]]

See `temporary-file-directory', too, if you want to use this, as the default may not be what you intend.


You might want to use this:

#+BEGIN_SRC emacs-lisp
=A0 (defun local-tfile (file)
=A0 =A0 (let ((temporary-file-directory "."))
=A0 =A0 =A0 (make-temp-file file)))
#+END_SRC

Then the files go in the local directory when this is executed:

#+BEGIN_SRC R :file (local-tfile "tfile") :results output append<= br> cat(date(),"\n")
#+END_SRC

You might not want `append' in this case.
