[x3d-public] JavaScript news from meeting with Don today.

[John Carlson]

More news:

We are working on a dual implementation of nodejs-X3DJSAIL stylesheets and
serializers.  Specifically, the technology that binds a high level node.js
API on top of X3DJSAIL is called npm-java.  While some of our code works,
there is some that doesn't.

On github, you can follow many of our examples under:

https://github.com/coderextreme/X3DJSONLD/tree/master/src/main/node/net

the coderextreme/data folder contains code from my NodeSerializer.js, and
the x3djsonld/data folder is from my X3dToNodeJS.xslt (perhaps out of date).

Here are the results from running my abox example:

$ node net/coderextreme/data/abox.js
Warning: ../data/abox.new.x3d does not meet suggested X3D naming
conventions, continuing...
Warning: toFileX3D() is overwriting prior file ../data/abox.new.x3d

[ success ]

$ node net/x3djsonld/data/abox.js
abox execution self-validation test results: TypeError: meta.getName is not
a function

[ failure ???? didn't check for file ]

I'm asking Don to look into the X3dToNodeJS.xslt stylesheet.  Don installed
nodejs on his platform today, so perhaps we can get a little more headway
on this.

www.web3d.org/x3d/stylesheets/java/node/examples/abox.js

run like

node.exe abox.js

or
node.exe examples/abox.js

Thanks!

We'd like to provide at least one working nodejs environment, albiet one
that runs with X3DJSAIL for now. Other implementations such as a XML to
X_ITE SAI converter and ES6 are still experimental or unfinished.  Higher
priority items appear to be my DOM2JSONSerializer.js for the browser, and
the ProtoExpander.js debugging.  Would someone want an XML to X_ITE SAI
converter?   Just asking!

Thanks,

John
