C++ variable declaration alignment.

C++ variable declaration alignment.

[Andrea Venturoli]

Hello.
I'm using emacs to code in C++ and I'm unhappy with how it alignes 
variable declarations.

What I get is:

double a,
   b;

What I'd like to get is:
double a,
        b;

Is there any way to do this?



Also, suppose I have:

return a==b||
   a==c||
   a==d;

I'd like to get:
return a==b||
        a==c||
        a==d;

Is this possible too?


  bye & Thanks
	av.

There may well be an easier answer - but I use the align.el package for any customised alignment issues. It is a great package written by John Wiegley and is a part of the Emacs distribution.

Thanks.
I tried it, but I'm not proficient with emacs lisp and found no good 
documentation (at least not good for me).
Is there any howto?

Have you tried the various alignment options? In my .emacs I have:
;; Indentation style 
  (setq c-default-style "stroustrup")
  
But I could have had one of several others. 'gnu', 'k&r', 'bsd',
'whitesmith', 'ellemtel, 'linux'...

Yes.
Unless I'm missing something, none of them does what I asked.
Am I missing something?

You're probably not missing anything. I just wondered whether you had
tried all the available options.

My approach was to look at all the supported indentation schemes and
decide which I liked best. Out of these, I preferred stroustrup. I
didn't feel strongly enough about it to think I needed to find or
invent another.

I had a need to make Emacs align C, C++, and Java code the way the rest of the organization was aligning by hand (with spaces in vi and other editors).  The way I got it to do what I wanted was to create my own "style" -- and that requires writing a small amount of Emacs Lisp....
