HTML/Java via CLI was: Using ikvm for xaml app

Thanks for your interest in HTML/Java APIs. My reply should be generally
interesting, so I am cross-posting to DukeScript mailing list. Netiquete
might suggest us to move our discussion there...

While I am naturally emotionally attached to NetBeans, I am over forcing
people to use the IDE. As such the whole system is usable from command
line. No IDE support is needed.

Nobody wrote it and expecting me to do it would be unrealistic. But it is
reported to work. Some evidence can be found at
http://wiki.apidesign.org/wiki/Bck2BrwsrViaCLI

It should work. It works in NetBeans (which still use Ant to build itself).
But when using Ant everyone is on his own - e.g. no reason to provide
special support to it. Just watch what "mvn -X package" does and mimic that.

The only non-standard issue to solve is bytecode post-processing explained
at
http://bits.netbeans.org/html+java/1.1/net/java/html/js/package-summary.html#post-process
and implemented in Ant scripts as
http://hg.netbeans.org/main-golden/rev/a5c35d44103c

As far as Gradle goes: I am unwilling to enter the IDE wars, and I have
even less reasons to enter the build tool ones. However I will be more than
happy if somebody implements and maintains Gradle support - again the only
special part is the bytecode post-processing.

It should be far more easier (unless I did poor job designing the whole
system) - enough to implement a presenter:
http://bits.netbeans.org/html+java/1.1/org/netbeans/html/boot/spi/Fn.Presenter.html
and pass a TCK:
http://bits.netbeans.org/html+java/1.1/org/netbeans/html/json/tck/package-summary.html

Btw. the most modern way to get started via CLI described at
http://dukescript.com/update/2015/02/05/New-Version-of-Dukescript.html also
contains references to repositories with implementations of presenters for
various platforms. I was planning to mimic one of the implementations and
just bind it to C#'s WebView.

I would certainly like to avoid forking IKVM libraries. I know Jeroen
warned me that some functionality won't work on Window Phone, but hopefully
the HTML/Java is using so little of OpenJDK (collections, WeakReference, no
reflection) that it might work.

Please start at

and share with us your observations.

Thanks again for your interest.
