Re: [gwt-contrib] GWT,jsni() implemented as rebinding method
BTW, my implementation of GWT.jsni() with rebinding methods was just to
show the power of the proposal, not to support the inclusion of the method.

Yes, GWT.jsni is one of the use cases for method rebinding; that was
something I was discussing as part of the original discussion.
In reality GWT.jsni is better to be implementable without "native"
method definitions so we could eventually take native methods out of the
compiler.
There are also other use cases like String.format, GWT.debugger and
GWT.create itself. The ideal solution should cover all to avoid redundant
features in the SDK.

Re: [gwt-contrib] GWT,jsni() implemented as rebinding method
Honestly, I think JSNI should be fully removed from GWT, even GWT.jsni().
JsInterop seems to cover all the JS binding cases, I can't see where JSNI
is still useful. JSNI is a dirty hack, it doesn't supports refactoring nor
typesafe and it's not really Java. In the other hand, a thing like
GWT.debugger() is ugly. It could be useful in JS development, but it
doesn't differs so much from Window.alert("Hi bro, I'm debugging the line
123"). We already have a debugger, who needs a debugger statement? GWT.*
methods are usually intrusive and source of code coupling.
That said, I see the need of method rebinding only at JavaToSimplerJava
level. JavaToJavaScript should be orthogonal, and fully covered by
JsInterop.
Of course, I'm really interested in enhance code generation. :-)

Yes, that is also true for the GWT.jsni case. I think at the end there
should be 2 types of rewriters; one for java and one for javascript and
they should do real method replacement. Developer can choose either one.
It looks like you are really interested in this. Can you also improve your
proposal with real method rewriting?

Re: [gwt-contrib] GWT,jsni() implemented as rebinding method
Well, there is a sample for String.format() in the prototype:
https://github.com/andrestesti/gwt-rebindingmethods/blob/master/samples/hellorebinding/src/com/google/gwt/sample/hellorebinding/client/util/Strings.java#L39
I agree, method rebinding should eliminate the need of magic methods and
simplify the compiler. GWT.debugger() is a controvesial case because Java
doesn't has a semantically equivalent for it..

[gwt-contrib] GWT,jsni() implemented as rebinding method
This morning I read the Goktug's slides and was surprised by the GWT.jsni()
method. It is a nice use case for rebinding methods. I just added a version
of GWT.jsni() to HelloRebinding sample, implementing it as a rebinding
method (no compiler mods). It took me just 30 minutes of coding to add an
extension to support this:
JsniUtil.jsni("$wnd.alert(#)", message);
