Re: [O] Python source block and :dir header arg

[Joao Cortes]

Looking at org-babel-execute-src-block, It seems the only way to get the
the intended behavihour is adding :mkdirp "yes" or some other
value that gives a true value to the result of the =and= call in the
following snippet.

This is the relevant code at ob-core.el, starting at line 681.
#+begin_src emacs-lisp :line yes
                 (default-directory
                   (or (and dir
                            (not (member mkdirp '("no" "nil" nil)))
                            (progn
                              (let ((d (file-name-as-directory
                                        (expand-file-name dir))))
                                (make-directory d 'parents)
                                d)))
                       default-directory))
#+end_src

This looks like a bug. If the :dir directory already
exists, the :mkdirp parameter should not stop setting the default
directory to :dir
