Hi all!

WebIDL recently introduced dedicated syntax for mixins.

This syntax replaces the [NoInterfaceObject] extended attribute and implements statement which have been deprecated (except for a few legacy uses cases explicitely mentioned in the spec).

You can read more about it here.

In most cases, the changes should be relatively straightforward. The now deprecated:

interface Foo { };

[NoInterfaceObject]  // (Mostly) DEPRECATED
interface Bar { };
Foo implementes Bar; // DEPRECATED

should just be rewritten as:

interface Foo { };

interface mixin Bar { };
Foo includes Bar;

Additonaly, a section on when to use partials and mixins has been added to the spec. It's short and might be worth a read.

It seems the following interfaces in this spec are impacted by this change:

  • HTMLHyperlinkElementUtils
  • CanvasState
  • CanvasTransform
  • CanvasCompositing
  • CanvasImageSmoothing
  • CanvasFillStrokeStyles
  • CanvasShadowStyles
  • CanvasFilters
  • CanvasRect
  • CanvasDrawPath
  • CanvasUserInterface
  • CanvasText
  • CanvasDrawImage
  • CanvasImageData
  • CanvasPathDrawingStyles
  • CanvasTextDrawingStyles
  • CanvasPath
  • ElementContentEditable
  • NavigatorOnLine
  • GlobalEventHandlers
  • WindowEventHandlers
  • DocumentAndElementEventHandlers
  • WindowOrWorkerGlobalScope
  • NavigatorID
  • NavigatorLanguage
  • NavigatorContentUtils
  • NavigatorCookies
  • NavigatorPlugins
  • AbstractWorker
  • NavigatorConcurrentHardware
  • WindowSessionStorage
  • WindowLocalStorage
  • External

We're sorry for the inconvenience this causes, but our hope is that this ultimately makes things simpler and clearer for everybody.

As always, please feel free to reach out if you have any questions.

Thanks!

From #3187, @annevk says:

I think we also need to block this on tooling as the HTML Standard is scraped for IDL. If that tool can no longer recognize our IDL all kinds of cross-references might go dead.

Use Web IDL's new-ish interface mixins concept
e157654 
WebIDL recently introduced dedicated syntax for mixins [1]. This replaces the
existing [NoInterfaceObject] and "implements" syntax with "interface mixin" and
"includes" in the appropriate places.

Closes whatwg#3194.
