[Matlab-emacs-discuss] matlab-shell-run-cell does *not* work as expected. Forward-page??

[Uwe B. <ou...@ma...>]

Hello 

Below you find a test file which works fine in built in
editor:

--8<------------------------schnipp------------------------->8---
%%
hallo

%%
disp('again')
y=8

%%

z=8--8
<------------------------schnapp------------------------->8---
when running on the first cell matlab complains about hallo
not being known, when running about the second cell
everything works fine.

As I mentioned in an earlier mail, matlab-shell-run-region
works in the current version contra intuitive. I don't know
whether the patch I sent was accepted.

In any case when I use matlab-shell-run-cell then
matlab-run-shell-region runs over the *whole* file
(GNU emacs 23.1 or Xemacs 21.5.31 Mule)

I debugged matlab-shell-run-cell:
The reason is the bizarre (forward-page -1)
which jumps to the beginning of the buffer

Before I start to experiment with the code:

    -  What is the purpose of the forward-page code?

    -  What is your opinion about the behaviour of
       matlab-shell-run-region?



(defun matlab-shell-run-cell ()
  "Run the cell the cursor is in."
  (interactive)
  (let ((start (save-excursion (forward-page -1)
			       (if (looking-at "function")
				   (error "You are not in a cell.  Try `matlab-shell-save-and-go' instead"))
			       (when (matlab-ltype-comm)
				 ;; Skip over starting comment from the current cell.
				 (matlab-end-of-command 1)
				 (end-of-line)
				 (forward-char 1))
			       (point)))
	(end (save-excursion (forward-page 1)
			     (when (matlab-ltype-comm)
			       (beginning-of-line)
			       (forward-char -1))
			     (point))))
   (matlab-shell-run-region start end)))
