In both modes (Python and ESS "Emacs Speaks Statistics") there is a function bound to the sequence: C-c C-n Both functions advance to the next line of code in the buffer, i.e., skipping blank lines, comment lines, etc. In ESS mode the function bound to C-c C-n also (by default) sends the current line to R for evaluation. I find this to be very convenient as a way to watch calculations "evolve". It's possible to do something similar in Python mode by selecting the current line and then sending the region (C-c C-r) to Python for evaluation, but this is a bit cumbersome. Can anybody suggest a way to graft the ESS-mode behavior onto Python mode?Try this: (defun my-python-send-region (&optional beg end) (interactive) (let ((beg (cond (beg beg) ((region-active-p) (region-beginning)) (t (line-beginning-position)))) (end (cond (end end) ((region-active-p) (copy-marker (region-end))) (t (line-end-position))))) (python-send-region beg end))) HTH Comments welcomeIsn't it simpler: (defun my-python-send-region (beg end) (interactive "r") (if (eq beg end) (python-send-region (point-at-bol) (point-at-eol)) (python-send-region beg end)))
"r" complains if no mark is set Did choose the default getting rid of that constraint
Otherwise, with cond you can write (cond (beg) (end)) instead of (cond (beg beg) (end end))
Indeed, will change this. Thanks
Andreas -- https://code.launchpad.net/~a-roehler/python-mode https://code.launchpad.net/s-x-emacs-werkstatt/I've appended the high-level descriptions of both functions. I understand that the source code is available, and that I'm free to hack away to my heart's content. I just don't have the skills at Emacs/Lisp required to do such a thing in a finite amount of time. Thanks and best wishes, -- Mike Python mode =========== C-c C-n runs the command python-next-statement, which is an interactive compiled Lisp function. It is bound to C-c C-n. (python-next-statement&optional COUNT) Go to start of next statement. With argument COUNT, do it COUNT times. Stop at end of buffer. Return count of statements left to move. ---------- ESS mode ======== C-c C-n runs the command ess-eval-line-and-step, which is an interactive compiled Lisp function in `ess-inf.el'. It is bound to C-c C-n, C-c C-e C-n,<menu-bar> <ESS> <ESS Eval> <Eval line& step>. (ess-eval-line-and-step&optional SIMPLE-NEXT EVEN-EMPTY INVISIBLY) Evaluate the current line visibly and step to the "next" line. "next" = the next line with non-comment code _unless_ SIMPLE-NEXT is non-nil, possibly via prefix arg. If 2nd arg EVEN-EMPTY [prefix as well], also send empty lines. When the variable `ess-eval-empty' is non-nil both SIMPLE-NEXT and EVEN-EMPTY are interpreted as true.
