Re: [Matlab-emacs-discuss] open selection.

[David C. <dav...@fr...>]

Hi Assaf,

I'm not a matlab-emacs expert, so there might be a way to just do that with
matlab-emacs.
However, the way I do it relies on emacs tags, which brings other advantages
(and surely drawbacks).

Download and install the latest version of exhuberant ctags
(http://ctags.sourceforge.net) as it natively supports matlab now (with
older versions I had to use complex regexps to parse matlab source files)

Then you can generate a tags table in the current directory with the
following shell command (do not remove the final "-")

In Windows:
dir /b/s *.m | ctags -e -o TAGS -L -

Or in Linux/Unix:
find . -follow -type f -name "*.m" | ctags -e -o TAGS -L -

Then instruct emacs to use this file, with M-x visit-tags-table.
Now you can jump to a function definition with M-x find-tag

If you want to just point to a function and open the source code for it, you
can just add to your .emacs something like:

(define-key matlab-mode-map [(C-return)]  (lambda () (interactive)
(find-tag(find-tag-default))))

What I find very convenient is that you can come back to the point where you
invoked the find-tag command with something like

(define-key matlab-mode-map [(C-backspace)] 'pop-tag-mark)

Now (C-return) and (C-backspace) respectively allow you to go lower and
higher in the functions call tree !

Hope that helps,
David.

Hi,

Is there a way to point on a function-name in the source-code and open 
it  -- like the open-selection (F4) option in matlab ?

A-ssaf
p.s: matlab-emacs is great!
