Dear python-mode maintainers,

I'd like to suggest adding the following command to python.el,
and binding it to C-<return> by default. I'd love to hear your thoughts.

(defun python-shell-send-paragraph (&optional send-main msg)
  "Send all lines of code between two white lines to inferior
Python process. SEND-MAIN defaults to nil and MSG to t.
See `python-shell-send-region for more information.
Interactively, SEND-MAIN is the prefix argument"
  (interactive "Pi")
  (python-shell-send-region
   (or (save-excursion (re-search-backward "^[:blank:]*$" nil t))
(point-min))
   (or (save-excursion (re-search-forward  "^[:blank:]*$" nil t))
(point-max))
   send-main (not msg) t))

With kind regards.
Machiel Kroon

Thanks.

Adding the relevant developers to the discussion.

Hi there,

>> Dear python-mode maintainers,

I'm not a `python-mode` maintainer, just a user, but here are my two cents:

>> I'd like to suggest adding the following command to python.el,
>> and binding it to C-<return> by default. I'd love to hear your

Regardless of the command, I'd consider picking another binding
(perhaps along side this one) since some users (including yours truly)
are used to press `C-m` instead of the `<return>` key.

>> (defun python-shell-send-paragraph (&optional send-main msg)
>>   "Send all lines of code between two white lines to inferior

>> See `python-shell-send-region for more information.

I'd say something like "SEND-MAIN and MSG have the same meaning as in
`python-shell-send-paragraph', which see." to make this more obvious.

>> Interactively, SEND-MAIN is the prefix argument"
>>   (interactive "Pi")

This is probably supposed to be `(interactive "P\ni")`?

>>   (python-shell-send-region
>>    (or (save-excursion (re-search-backward "^[:blank:]*$" nil t)) (point-min))
>>    (or (save-excursion (re-search-forward  "^[:blank:]*$" nil t)) (point-max))

This method of finding the boundaries of the paragraph at point seems
slightly ad-hoc and fragile, I wonder what happens if there's a blank
line in the middle of a multi-line string?

>>    send-main (not msg) t))

Just a couple of thoughts :)

Best,

Right, I hadn't thought about empty lines in any kind of statement. I guess
I got too excited after learning a little bit of lisp, and thinking the
function was so beautiful. I'll think about making it more robust. Thanks
for the response!

Update: I've been using the following this afternoon and haven't run into
any issues so far. However, it looks a bit messy.

(defun python-shell-send-paragraph (&optional send-main msg)
  "Send blocks between two white lines to inferior Python process.
See `python-shell-send-region' for SEND-MAIN and MSG."
  (interactive "P\ni")
  (let ((start
         (save-excursion
           (if (re-search-backward "^[:blank:]*$" nil t)
               (let ((pos (point)))
                 (python-nav-end-of-block)
                 (if (< (point) pos) pos
                   (progn (python-nav-beginning-of-block) (point))))
             (point-min))))
        (end
         (save-excursion
           (if (re-search-forward  "^[:blank:]*$" nil t)
               (progn (python-nav-end-of-block) (point))
             (point-max)))))
    (python-shell-send-region start end send-main (not msg) nil)))

Hi, it would be better to clarify what a paragraph in Python-mode is
and explain why it would be useful to be able to send it to Python
shell.  For example, is the line "b = 2" a stand-alone paragraph?

def func():
    a = 1

    b = 2

It's not clear to me how the proposed function differs from M-h followed
by C-c C-r (mark-paragraph then python-shell-region).  When developping
in Python, I sometime use this sequence but I wouldn't learn a new key
binding for this.  Still, it's only a user pov, I am not a python-mode
maintainer.
