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","!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?
