Bug 108565 – [CPP,GObject,ObjC] Add 'enum' skip to CodeGenerator{CPP,GObject,ObjC}.pm

• Component: WebKit Misc.
• Status: RESOLVED FIXED

[Nils Barth]

Make legacy code generators skip enum types (added to V8 CodeGen in Bug 106553).
This allows us to not use macros like "#if defined(TESTING_JS) || defined(TESTING_V8)" in IDL files.
Concretely it's just adding an IsEnumType check to the SkipAttribute functions, and then removing macros from the test IDL file.

Simple patch -- adds IsEnumType test to SkipAttribute in legacy code generators
so we can remove #if macro from IDL test file.
Also minor associated code cleaning (b/c we're checking type):
aux var: $type = $attribute->signature->type
(is this ok?)

Please explain the rationale for the change, not only what you did but also why you did it.

e.g. Since CodeGenerator{CPP,GObject,ObjC}.pm does not support 'enum', this patch adds code to skip DOM attributes that return 'enum'.

> Source/WebCore/bindings/scripts/test/TestObj.idl:47
>      static readonly attribute long     staticReadOnlyLongAttr;
>      static attribute DOMString         staticStringAttr;
>      static readonly attribute TestSubObjConstructor TestSubObj;
> -    attribute TestEnumType             enumAttr;
>  #endif

I think you can remove this #if too by skipping 'static' in CodeGenerator{ObjC,GObject,CPP}.pm. You can do it in a follow-up patch.

I was wondering about that; should I open a different bug for that?
