ObjC mode fontification and formatting

ObjC mode fontification and formatting

[Raffael Herzog]

Hi,

Playing around with GNUstep I also started Objective-C pro-
gramming. Now, there are some issues with cc-mode there:

,----
| -(void) doSomething: (NSString*) str1
|                with: (NSString*) str2
| {
|     [anObject doSomething: str1
|               with: str2];  // 'with' is fontified as
|                             // function definition, 'str2'
|                             // as variable
| }
`----

But I'd like Emacs to do the following:

,----
| -(void) doSomething: (NSString*) str
|                with: (NSString*) str2
| {
|     [anObject doSomething: str1   // fontify 'anObject' as
|                                   // variable? (not sure yet)
|                      with: str2]; // don't fontify 'with'
|                                   // nor 'str2'
|    // note the alignment ^
| }
`----

How can this be done?


TIA,

   Raffi

  The difference between theory and practice is that in theory, there is
                 no difference, but in practice, there is.

I don't really understand what's going on, but with a bit of
experimentation I got the following, which seems to work:

   (c-set-offset 'objc-method-call-cont
                 (lambda (x) (- (c-lineup-ObjC-method-args-2 x) 2)))

There's probably something less kludgey than subtracting 2, but I don't
know what it is...

[c-set-offset is `C-c C-o' in objc-mode]
