Hi max,

Glad you like AngularJS Eclipse features.

It should be very cool if my work could be integrated in JBoss Tools,. I
have a lot and lof of idea to improve it not only for angular but for
Javascript features like refactoring, hover, validation.
I think tern.java should be refactored again and IMHO I think we should
waiting that tern.java is stable if you wish to integrate to JBoss. More
some tests of performance must be done (I believe that Victor works on
that).

I would like to convince that tern could be a good idea to integrate with
Eclipse IDE.
I love tern bebcause it's very powerful, very extensible and it works with
webbrowser too. After playing with tern, it seems that Tern inference
engine is more powerfull than JSDT.
For instance, see screeshot below with completion about event (JSDT cannot
do that according my test) :

Tern provides a easy mean to write some JSON definition. For instance you
have a jquery def
https://github.com/marijnh/tern/blob/master/defs/jquery.json which manages
that :

This feature is managed just with a simple JSON :

 "on": {
        "!type": "fn(events: string, selector?: string, data?: ?,
handler: fn(+jQuery.Event)) -> jQuery.fn",
        "!url": "http://api.jquery.com/on/",
        "!doc": "Attach an event handler function for one or more
events to the selected elements."
      },

It declares just that handler is a function which waits a jQuery.Event and
that's all!

I'm studying how to manage validation with Tern. here a screenshot with
CodeMirror :

Today I think node.js doesn't please you, but tern.java provides an API to
use tern.js with other javascript engine (I had implemented with Rhino, but
it's too slowly and outofmemory problem, but what about java8 nashorn?

Regards Angelo
