Re: [m2t-dev] EMF 2.6 for Xpand 0.8.0?
|
Would it be possible to implement that support in a fragment of
o.e.xtend ? Support for EOperations is requested with this feature
request:
https://bugs.eclipse.org/bugs/show_bug.cgi?id=297515
It is important that we do not require Eclipse 3.6 for core plugins
whenever possible.

Hi guys,
M2T Xpand is currently built against EMF 2.5. This is a good thing to
guarantee stability and compatibility for our users. However there's
a nice
little feature that I would like to contribute to Xtend that
requires EMF 2.6.
EMF 2.6 can now delegate the invocation of EOperations and the
getter/setter
calls of EStructuralFeatures. It was pretty easy to come up with an
implementation that allows you to specify the behavior of operations
and the
computation rules for derived properties (or even the behavior of
non-trivial
setters) with Xtend :-) All you need is some annotations in the
*.ecore file.
The behavior implementations themselves can either go inline into
the ecore
file as well, or be specified externally in *.ext files (in order to
make use
of content assist et al). I can check in a preview version if anyone
is
interested.
Building everything against the EMF 2.6 SDK is probably not a good
option,
since this requires the Eclipse Platform 3.6. It's probably too
dangerous,
because we might accidentally introduce dependencies to EMF 2.6/
Platform 3.6
code and break our clients. What do you think? Is there a way to do
this
gracefully?
Cheers,
Achim
