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.

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?

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?

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....
