I have following query,

In cc-mode

whenever I type `(', I want emacs to automatically insert space before it,
just for symbols [if | while | for | switch] during typing;


How it can be done ?

Thanks,
Manish

Thanks for your help.

I got a hint from `http://www.emacswiki.org/emacs/LineCopyChar'
and I added,

(defun insert-paren-pair (&optional b)                                                                                                                      
  (interactive "p")                                                                                                                                         
  (let (p col s)                                                                                                                                            
    (setq p (point))                                                                                                                                        
    (setq col (current-column))                                                                                                                             
    (move-to-column col)                                                                                                                                    
    (goto-char p)                                                                                                                                           
    (insert " ()")                                                                                                                                          
    (goto-char (- (point) 1))))                                                                                                                             
                                                                                                                                                            
(define-key global-map (kbd "M-(") 'insert-paren-pair) 

to my .emacs

this won't solve the original problem, but for specific keywords it will suffice.

It's not at all clear why you needed to do this, since M-( is normally bound to insert-parentheses.  (AFAIK, it has been this way for decades.)

Regarding making the '(' character do this, by convention, it would be an "electric" function, and it's probably not very hard to write.  You might even be happy just binding '(' to insert-parentheses.

Hope this helps,
Mark

There is curious synchronicity on this topic, because my colleagues are reviewing some of my code this week and are challenging me about the spaces before the argument lists for function calls.  (They mostly use 'vi'....)

Normal Emacs behavior using M-( results in the following (could be Java or C):

   if (foo1 (bar, baz))
      foo2 ();

What we want is:

   if (foo1(bar, baz))
      foo2();

That is, we only want a space to be inserted after a language keyword.  Has anyone hacked this (presumably as part of or in conjunction with CC Mode) for conditionally adding the space before the open parentheses?  The reason I expect it to be related to CC Mode is that it's the fact that "if" is a language keyword that makes the difference, and CC Mode already knows about the keywords.  Looking at insert-parentheses and insert-pair, it seems as though insert-parentheses could be wrapped in something like cc-insert-parentheses to do this.  That's what I'll start doing if no one else pipes up....

Thanks!
Mark

Well when we use `insert-parentheses' it inserts parentheses immediately without any space character like this -

`if()'; but the following binding inserts as `if ()'

Thanks,
Manish

I started the topic due to same issue.
I used `paredit.el', but it also did in the same manner you showed - inserting spaces even after function call parenthesis.

Have to check how to modify cc-mode `(' binding...

Thanks,
Manish
