Abbrev , as ,_

[Jiri Pejchal]

When I code in Java or C++ I always type space after ",".
For example foo(a, f)
                  ^                
                  |
                  
Can Emacs put the space there automatically?
I tried to make an abbrev for it, but it didn't work for me.

You could do something like this:

(define-key c-mode-map "," (lambda ()
			     (interactive)
			     (insert ", ")))

Out of curiosity, wouldn't that mean that typing in:

foo = "1,2,3,4,5";

Would create:

foo = "1, 2, 3, 4, 5";

And cause problems?  Granted many times commas and spaces go hand in
hand, but in scenarios like a CSV list it would be horribly wrong.

Here is the solution, it don't expand in comments, strings and others 
contexts.

(define-key c-mode-map ","
   (lambda ()
     (interactive)
     (let* ((face (get-text-property (point) 'face )))
     (if
	(or (equal face 'font-lock-comment-face)
	    (equal face 'font-lock-string-face)
	    (equal face 'font-lock-warning-face)
	    (equal face 'font-lock-doc-face))
	(insert ",")
	(insert ", ")
       ))))

[ Try to use TAB to indent your code, so it's easier to read for others. ]

AKA

   (insert
    (if (member (get-text-property (point) 'face)
                '(font-lock-comment-face font-lock-string-face
                  font-lock-warning-face font-lock-doc-face))
        "," ", "))
