With our investigation into E4 we have a lot of interest in scripting
eclipse. Both the general "I just want a few helper scripts" to
"JavaScript support since we'll support the web as well".
Some areas I'm interested in are the DOMs (how to get them right, how to
plug them in, are there opportunities for metadata to help with tooling,
etc) and the execution engines.
We've done some simple examples that use rhino where we've started it
ourselves (we use rhino from the Orbit project), and I'm interested to
see how Eclipse (Groovy) Monkey manages the runtimes.
You can contact me directly, and I monitor this newsgroup ... we're also
on irc://freenode.net in the #eclipse-dev and #eclipse-e4 channels.
