[mdt-ocl.dev] Re: Need advice
|
Hi Sébastien
Glad to hear from you. I was afraid that we'd frightened you away.
All org.eclipse.emf.ocl plugins have been deprecated for some time. In
MDT/OCL 3.0.0 we are eliminating them. Except that
org.eclipse.emf.ocl.examples.interpreter is clearly useful and still works.
Your new plugin should probably be called org.eclipse.ocl.evaluator or
perhaps org.eclipse.ocl.console.evaluator.
Please 'duplicate' org.eclipse.emf.ocl.examples.interpreter as perhaps
org.eclipse.ocl.console.ui. Your 'duplicate' will be
included within an OCL console feature. If the 'duplicate' is trivially
different (less than 200 useful lines), please supply it as a separate
patch so that we can bypass IP procedures. Please feel free to review
your 'duplicate' if you feel that the API is inappropriate for your
foreseen usages. We can easily change the API now; after Helios it will
be awkward.
My suggestions above are just suggestions, so if you have better ideas,
please put them forward.
Christian's OCL completion is useful, but requires an independent
intuitive grammar, which is plausible for just expressions. It does not
expand well to OCL documents or QVT transformations. For these purposes
the backtracking parser has been activated to make grammar-driven
suggestions. I would prefer to enhance the grammar-driven approach so
that we do not have two different bodies of completion code. The
Issue 10439 / Bugzilla 292112 grammar may make this more tractable.

Hello Ed,
To make short : I am currently working on the OCL Evaluator I would
like to contribute to Eclipse in the next weeks (days ?) to come.
I offer an OCL syntax completion in an input field (as it is done in
the OCL interpreter). For that, I reuse the code developed by
Christian Damus. It works fine ! Great ! But it rises a problem of
dependency between plug-ins. Currently, my plug-in (named
org.eclipse.emf.ocl.evaluator) have a dependency to
'org.eclipse.emf.ocl.examples.interpreter' and I am not really sure
that it is the best way to proceed since this example plug-in needs to
be generated by end-users. My question is the following : Should I let
this dependency or should I duplicate code I need (or other solution )
? Please, I need advice about this point.
Do you understand my issue ?
Thanks !
Regards,
Sébastien
