Improve completion with tern?

[angelozerr]

I don't know coffescript, but I tell me if we could improve coffescript completion with https://github.com/othree/tern-coffee and https://github.com/angelozerr/tern.java

There is show stopper #19

This project is using Xtext that is a beast, quite a thing to learn.

I can't tell how it is possible to add completion for XText based solution

Thank's for your answer @paulvi

If I see that there are people who could be interested with coffescript completion, I will study how to use https://github.com/othree/tern-coffee with a simple editor part and after how to extend XText completion
