Can this be internal to ModifierKeyExtractor?

How about:

@interface ModifierKeys : NSObject {
@public
    NSString *eventCharacter;
    unsigned short keyCode;
    NSString *charactersIgnoringModifiers;
    int modifierFlags;
}

+ (ModifierKeys*)modifierKeysWithKey:(NSString *)key modifiers:(int)modifiers keyLocation:(unsigned)keyLocation;

> Tools/WebKitTestRunner/mac/EventSenderProxy.mm:633
> +        modifierFlags:modifierKeyExtractor->modifierFlags

modifierKeyExtractor.modifierFlags here and elsewhere.

Oh yes, good catch.

Okay! Will work on this rename. I suppose I should rename the file too.

Slightly confused by this last piece of feedback. First, modifierKeyExtractor should probably be renamed to modifierKeys, yes? Second are you suggesting that the instance variables should be properties instead? I don't think that the suggested interface you typed out above makes that change from ivar to property. I might be missing the point of this piece of feedback though. Please help.

This needs to be a class method :
+ (ModifierKeys*) ...

> Tools/TestRunnerShared/cocoa/ModifierKeys.mm:45
> +- (ModifierKeys*)modifierKeysWithKey:(NSString *)character modifiers:(int)modifiers keyLocation:(unsigned)keyLocation

This should be an init method, then you need the class method that alloc/inits the object then returns it.

> Tools/TestRunnerShared/cocoa/ModifierKeys.mm:240
> +    return self;

return [self autorelease];

And you need a -dealloc to not leak!

For the init method this is fine. The class method will return an autoreleased object.

What's going on here

> Tools/TestRunnerShared/cocoa/ModifierKeys.h:32
> +    RetainPtr<NSString> eventCharacter;

public ivars in objc is quite unusual these days (vs. properties), but this is also fine, especially since you're just using it to replace what was a struct.

> Tools/TestRunnerShared/cocoa/ModifierKeys.h:38
> ++ (ModifierKeys*)modifierKeysWithKey:(NSString *)key modifiers:(int)modifiers keyLocation:(unsigned)keyLocation;

`ModifierKeys *`

> Tools/TestRunnerShared/cocoa/ModifierKeys.mm:34
> +#if PLATFORM(IOS_FAMILY)
> +#import <WebKit/KeyEventCodesIOS.h>
> +#import <WebKit/WebEvent.h>

Chaotic ordering (#ifdeffed ones should come in separate paragraph unless they can't for some reason), and also mixed import/include.

> Tools/TestRunnerShared/cocoa/ModifierKeys.mm:40
> +    NSString* characterName;

"star's on the wrong side"

> Tools/TestRunnerShared/cocoa/ModifierKeys.mm:61
> +    ModifierKeys *modiferKeys = [[ModifierKeys alloc] init];

This LOOKS like a leak if you don't see the autorelease 500 miles away at the bottom of the function. Autorelease here instead!
