Hi,
I am creating an RCP application that allows to create, run and debug scripts using Rhino. I already have a GUI that allows to edit scripts using an editor with syntax highlight, debugging and running the scripts.
It wasn't until I decided to add code completion, hover help and a code tree that I found about DLTK while researching on the topic. I would really appreciate an advice at this point on what is better for me to do:
1. I could discard the current work and start from scratch trying to integrate DLTK JavaScript in my application.
2. I can keep my current work and try to use DLTK to build the AST and reuse as much as I can to provide code completion, hover help and a code tree.
My application extends JavaScript with some classes of my own, so whatever approach I take needs to allow this. Also, while following the Python tutorial it seems to me that DLTK is meant to be used in Plug-in Projects only, because it seems to rely heavily in Eclipses IDE features like project natures. Is it possible to integrate DLTK in a RCP application?
Is there any place where I can have more information about how to do this?
Thank you,
Milton.

Hi Milton,
Sorry for the late answer.
I think both projects win if you would use DLTK Javascript directly.
You are right that DLTK Core depends on org.eclipse.core.resources and EMF. It's hard to avoid them anyway, since other Eclipse subsystems (Debug, Editors, etc.) also depend on resources.
So, you just include these plugins into your RCP application and users' projects would be setup in the workspace, etc. like it works for you now in JDT 
Going this way would allow you to use DLTK plugins directly, without need to copy & paste individual classes, etc., so it's much easier for you to upgrade.
Also I hope that you would provide back some patches/improvements/extensions.
For development related questions it would be better to subscribe to dltk-dev@eclipse.org since it has more subscribers, etc.
Regards,
Alex
