Hi Jim,
Here is a tweaked version of the Matlab-comment function that should fix the
problem you found. If it works for you let me know and I can update it.
Enjoy
Eric
(defun matlab-comment ()
"Add a comment to the current line."
(interactive)
(cond ((matlab-ltype-empty) ; empty line
(matlab-comm-from-prev)
(if (matlab-lattr-comm)
(skip-chars-forward " \t%")
(insert matlab-comment-line-s)
(matlab-indent-line)))
((matlab-ltype-comm) ; comment line
(matlab-comm-from-prev)
(skip-chars-forward " \t%"))
((matlab-lattr-comm) ; code line w/ comment
(beginning-of-line)
(re-search-forward "[^%]%")
(forward-char -1)
(if (> (current-column) comment-column)
(delete-horizontal-space))
(if (< (current-column) comment-column) (indent-to
comment-column))
(skip-chars-forward "% \t"))
(t
; code line w/o comment
(end-of-line)
(re-search-backward "[^ \t\n^]" 0 t)
(forward-char)
(delete-horizontal-space)
(if (< (current-column) comment-column)
(indent-to comment-column)
(insert " "))
(insert matlab-comment-on-line-s))))

Subject: [Matlab-emacs-discuss] recognizing comments
I have noticed a small problem in the recognition of comments. I can use M-;
to insert a comment on the current line. I should be able to use the same
command to move point to an existing comment on the current line, with the side
effect of moving that comment to the preferred start column. Actually that
does work if the comment starts with "% ", but fails if the percent is followed
by something other than a space.
Suppose I am editing this file with point anywhere on the third line:
function foo
a = 3;
b = 4; %first comment
c = 5;
d = 6;
e = 7; % second comment
f = 8;
If I press M-; I get:
function foo
a = 3;
b = 4; %first comment
c = 5;
d = 6;
e = 7; % second comment
f = 8;
With point on any other line, I get the expected result.
I expect this could be fixed by adjusting a regular expression, but I could not
follow the logic well enough to find it.
