[Matlab-emacs-discuss] resend:matlab-shell-run-cell can only run one cell, narrow-to-region

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

Hello

I am sorry that I missed the change to the new list.
Here is a copy of an email I just sent to the old list (and
to Eric)



I tested this in GNU emacs Xemacs 21.5.31 and Xemacs
21.4.21:

matlab-shell-run-cell can only run one cell, all others
cells below are ignored:
the cells of the following example 
,----
| %%
| x=8
| 
| 
| %%
| y=91
| 
`----
Are executed in the built in editor but in all the Emacsen I
tested only x=8 is executed, the other command is ignored
which is odd.


The only solution consists to use narrow-to-region for a
cell and then use the function: matlab-shell-run-cell.

So I presume the function should be modfied. I tried that
but I can't get narrow-to-region    
(narrow-to-region start end) to work:

(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))))
     (save-restriction
     (progn 
   (narrow-to-region start end)
   (matlab-shell-run-region start end)))))
