Objective C coding style

Objective C coding style

[Samuel Bronson]

I've noticed that the Objective C code of the NeXTstep port doesn't  
have a very consistent style.  I expect this is something to do with  
the fact that (standards.info) doesn't cover Objective C.  Would it be  
appropriate to adopt the GNUstep coding style?

How does that style look?  Is it "compatible" with the GNU C-style, for example w.r.t. braces?

Yes.  The GNUstep coding standards make normative reference to the GNU  
coding standards, summarize some of the more important rules, and lay  
down rules regarding the additional constructs and namespaces found in  
Objective C.

For example, they dictate where the whitespace should go in method  
signatures, how message expressions may be indentented, and how  
classes and methods are to be named.  There are a few GNUstep-specific  
rules (like prefixing GNUstep-only class names with GS), but those are  
easy to spot and ignore.

I think it would be a good addition, but I guess it is up to the cc-mode developers.  There is currently no ObjC-style in cc-mode.  But ObjC is not well handeled by cc-mode (c-defun-name does not work at all with ObjC for example), so I am not optimistic.

Another question is if it should be the default for just the Emacs project or globally.

It's probably no coincidence that the main NS port developer at the time
posted a patch to improve cc-mode's handling of objective-c. I don't
know if anything ever happened with it: http://debbugs.gnu.org/299

I see you have a patch for that: http://debbugs.gnu.org/7879  (also 9032)
I'd just install it if I were you.

In my experience, these patch have been integrated.

I did so.
