[x3d-public] Possible error in X3dToNodeJS.xslt? LayerSet handling, multiple Mantis issues, class simplification for Java/Node SAI

Yes, a temporary prefix. autoclass is the first step, then shortening
later.
Thus:
let autoclass = require("./X3Dautoclass.js"); // should already be present
let X3D = autoclass.X3D;
// need a let for every X3D-based constructor used in file.
new X3D(); // without the autoclass.
We can work on changing the stylesheet Monday.
I am not sure how else to do this besides using ES6 imports. Hence my
desire to use ES6. Possibly we could use a NodeJS file as an ES6 module?
If you want to work on an X3dToES6.xslt as alternative to X3dToNodeJS.xslt,
that would be cool. I have tapped my friend Jeff to work on
something that imports XML and populates my ES6 library, but not sure if
he's going to do it or not. You're welcome to have your hand at it. I
have somewhat tested way of importing JSON. But outputting XML from the
data structure seems problematic, even though I've exported XML in other
places.
Code is at: https://github.com/coderextreme/es6x3d
I think you want to focus on X3DOM, possibly providing an SAI for it. I've
gone a long way towards that with my Script.js file in X3DJSONLD, but I
need to hook my code into the X3DOM event loop, I think.
https://github.com/coderextreme/X3DJSONLD/blob/master/src/main/node/Script.js
A key issue for X3D4 is the integration of Scripts and ROUTEs in X3DOM.
The above is my first attempt at it. Is anyone else working on this?
Likely this is more important to X3D4 than Protos is. Leonard suggested
that Scripts came *before* Protos.
Maybe create an agenda for the Monday meeting?
I apologize for not documenting my trail through ECMAScript. I am trying
to do that in bits and pieces now.
Thanks,
John
