ZERR Angelo commented on JBIDE-19184:
-------------------------------------

Tern takes time when there are a lot of JS files. I have written a wiki page about this problem at https://github.com/angelozerr/tern.java/wiki/Tern-Performance

Since 0.9.0, MyEclipse has contributed to synchronize tern files on background. So when completion takes too long time, Eclipse doesn't freeze. See https://github.com/angelozerr/tern.java/wiki/New-and-Noteworthy-0.9.0#async-tern-completion

To provide this feature, tern was a lot refactored and so it's very hard to move this feature to 0.8.x. I'm really sorry guys for that -(

This async feature is the first step to manage a lot of JS files. There are other issues like

* improving tern script path (support of exclude path, improve JSDT -> tern script path) See https://github.com/angelozerr/tern.java/issues/150 
* use condense tools https://github.com/angelozerr/tern.java/issues/193

So 0.9.0 will provide the async completion and linter support (ESLint, JSHint, etc). See https://github.com/angelozerr/tern.java/wiki/Tern-Linter

If I have time, I will try to improve tern script path.
