Re: GWT 2.8.0-beta1 JsInterop HTML5 classes ?

Hi

I have a half-baked tool that can convert most WebIDL to JSInterop. You can try it out.

https://github.com/rhmoller/embrace

You can drop .idl files containing pure webidl or .html files containing webidl fragments (like the specs from w3 and whatwg) into to the

webapis/data folder

and it will generate a gwt module for you if you run

./gradlew :webapis:jar

The gwt module is now in

webapis/build/libs/webapis.jar

In order to bootstrap it you need a bit of JSNI like this

https://github.com/rhmoller/embrace/blob/master/examples/src/main/java/com/giddyplanet/embrace/examples/client/Examples.java#L83-L89

Regarding Enums: I don't think it is supported. It would be nice if we could create a Java enum and have an annotation for specifying the JS value for each enum value. I have the same problem in the embrace tool. WebIDL enums are Strings and some of the enum values in some specs are not valid Java identifier. So currently I generate an oldschool interface with constants.

Best regards
Rene

Is there a way to generate JsInterop compatible classes/interfaces for all HTML5 javascript features ?

I'm interested in the new File API's, XMLHttpRequest, EventHandlers, ... etc. I can type it by hand, but

somebody must have done the work already or there must be a tool available to generate it ?

What I am missing right now is: how can I map Java enums to integers in an JsInterop interface ?

For example the HTML Event type contains this:

  const unsigned short NONE = 0;
  const unsigned short CAPTURING_PHASE = 1;
  const unsigned short AT_TARGET = 2;
  const unsigned short BUBBLING_PHASE = 3;
  readonly attribute unsigned short eventPhase;

I would like to expose these as java enums ... is that possible ?
