[Matlab-emacs-discuss] running a block of code

[Jody K. <jk...@uc...>]

Hi all,

In light of the new mailing list I thought I'd share this.  I kludged  
up the following snippet to mimic the Matlab editor's ability to run  
a block of code between two "%%" markers.   It also allows you to use  
"paragraph-forward" and "-backwards" on chunks of code.

Cheers,  Jody


(defun jmk-matlab-parastart ()
   "Set the paragraph start for matlab mode."
   (interactive)
   (make-local-variable 'paragraph-start)
   (setq paragraph-start "^\%\%" )
   (make-local-variable 'paragraph-separate)
   (setq paragraph-separate "^\%\%" ))

(add-hook 'matlab-mode-hook 'jmk-matlab-parastart)

;; Matlab function for evaluating the current "paragraph"
(defun jmk-matlab-run-para ()
   "Run the current paragraph."
   (interactive)
     (save-excursion
       (if mark-active (matlab-eei-eval-region (region-beginning)  
(region-end))
	(backward-paragraph)
	(setq beg (point))
	(forward-paragraph)
	(setq end (point))
	(matlab-eei-eval-region beg end))))

Hi,

  Thanks.  I know this feature is something I have had some requests
for.  I like the idea of using paragraph-start, though I do not know
the origins of the current values. Another option might be to use
page-delimiter instead.  What is a paragraph of M code anyway? ;)

Something Mathworks has in it's Editor. i.e.

%% Do something
% this is a "paragraph"
x=1:100
y = cos(x);

%% Plot something
% this is another "paragraph"

plot(x,y)
xlabel('x');
ylabel('y');

%%%%

I find it very useful to run parts of long scripts this way.  When  
analyzing data you can either make an m-file for each "block" of  
code, which gets unwieldly fast, or do it all in one long script.    
Usually the script takes too long to run everytime you want to change  
the xlabel on a plot so running bits of it is very convenient. You  
can highlight a block and run it, but that requires more keystrokes.   
Blocking the code like this is invaluable to my work flow.

Cheers,  Jody
