Hi Riccardo,

SimpleWebKit has its own JS interpreter (ECMA-Script)...

=
https://git.goldelico.com/?p=3Dswk.git;a=3Dblob;f=3DSources/ECMAScriptPars=
er.h;h=3Ddf2117b53feb6bbc107ffe03a51d26a4ef57c321;hb=3D18944b0223a4a85c7f3=
38f8dacce071f7fb0d97e=EF=BF=BC

The main missing thing is how to manipulate the DOM tree objects and =
provide them to the JS language so that
a script can really modify what is being displayed.

And it has not been significantly tested and may be incomplete (haven't =
used it for years).

So to me it seems easier to fix issues than squeeze in a probably =
incompatible library API.

Well, there is another thing to be considered:
SWK is a WebKit including the WebDOMOperations and WebScriptObjects for =
JS.

I have never checked what the newer WKWebView has changed. It could be a =
completely new architecture.
So we might need a SWKWebView...

And finally there is now a JavaScriptCore framework.

So Apple seems to duplicate already existing functionality in multiple =
frameworks and it is not clear
if they are related or build on top of each other.

BR,
Nikolaus
