2° Delegate JavaScript features to other components liek tern
On this topic, I suggest the following changes in JSDT that I find as
working enough for my experiments regarding merging Tern Outline into
JSDT Outline:
* Remove some extension points that are covered by upstream
frameworks. Mainly the Common Navigator, which makes it easy to write
an extensible Outline or a Quick Outline, without need to add other
extension points. For example, the "javaScriptElementFilter" extension
point could be replaced by usage of the commonFilter.
This is not a critical issue for extensibility, but removing code in
JSDT without loosing funcitonality nor extensibility is something that
we'll all see as a good thing.
This sounds reasonable. I think WTP policies prevent us from removing
the APIs immediately however we can deprecate "javaScriptElementFilter"
in favour of commonFilter.
All it needs is a bugzilla record and a patch to
"javaScriptElementFilter" for deprecation notice.
* Take advantage of adapters: in most classes where we want to have
extensibility, JSDT directly uses or casts to its types
(IJavaScriptType, IJavaScriptUnit, IJavaScriptElement...). Extenders
projects may not use directly these types but might be able to adapt
to the specified types relying on the Core adapter framework. By
leveraging that and checking for adapters when possible, several
pieces of JSDT code would remain working with the parts of extending
frameworks. Current JSDT Outline filters are an example: Tern can
provide its own richer elements to Outline, but since they're not JSDT
types, filters don't work. Assuming JSDT would check for adapters and
Tern would provide adapters, filters would remain working even with
Tern content. We can imagine similar thing for refactorings, search
and others.
