Thanks a lot for setting me on the right track! I am quite surprised
(coming from ess as my interface to R) that multiple named sessions
aren't supported out of the box for python.
I use your code now, which in my use-case works great. Only slight
variation: I set the default python process-name to the session name
using these two functions:
#+BEGIN_SRC emacs-lisp :results none
(defun al-org-babel-get-session (&optional arg info)
"Return the :session of the current source-code block.
Will return
- nil if :session is given but not named
- \"none\" if no :session argument is specified
- the session name otherwise"
(interactive)
(if (org-src-edit-buffer-p)
(let ((beg org-src--beg-marker))
(with-current-buffer (org-src--source-buffer)
(goto-char beg)
(al-org-babel-get-session)))
(let* ((info (or info (org-babel-get-src-block-info)))
(params (nth 2 info))
(session (cdr (assoc :session params))))
session)))
(defun kdm/my-py-sh-get-proc-name (dedicated)
(let* ((sessionname (al-org-babel-get-session))
(defaultname (or sessionname (if (equalp sessionname "none")
(buffer-name)
sessionname))))
(if (boundp 'py-buf-proc-name)
(format "%s" py-buf-proc-name)
(setq-local py-buf-proc-name
(format "%s"
(completing-read "Python session name: "
nil nil nil defaultname nil defaultname))))))
#+END_SRC
Thanks again,
Andreas
