Make elpy-shell-send more intelligent

Question

How can I modify (or replace) elpy-shell-send-region-or-buffer (bound to C-c C-c) to behave like ess-eval-region-or-function-or-paragraph-and-step, i.e.

1. if region is active, evaluate it (this currently works), goto 4.
2. if inside a function, evaluate it, goto 4.
3. evaluate current paragraph
4. Jump to the beginning of next paragraph

Thank you very much!

Answer 1

I haven't tried this thoroughly, but should work: 1. if region is active, evaluate it (this currently works), goto 3. 2. if region not active, evaluate current statement, goto 3. 3. Jump to the beginning of next paragraph

(defun python-shell-send-region-or-line nil
  "Sends from python-mode buffer to a python shell, intelligently."
  (interactive)
  (cond ((region-active-p)
     (setq deactivate-mark t)
     (python-shell-send-region (region-beginning) (region-end))
     (python-nav-forward-statement)
 ) (t (elpy-shell-send-current-statement))))

Taken from this answer.

elpy-shell-send-region-or-buffer is meant only to send entire buffer or a region.

If you want to step through code, you should use elpy-shell-send-current-statement, which is bound to C-ENTER. This function sends current statement to Python shell and advances to next.

If you want to send entire function, you have to use python-shell-send-defun which is bound to C-M-x.
