Hi Adolfo
Just got down to 8 errors from 2000-odd; mostly simple changes. The
residue is one harder problem that Xtext now does what I had to
workaround so may need a simplication in my code.
One trivial change is that the MWE script and its dependencies must
be deleted from the ocl-releng plugin; no point mending it, since
there is a new examples build plugin.
The to-M5 transition may be a bit tricky, since for M5+1 we probably
cannot use Xtext 2.0 M4, so M5+1 may need to be build against an I/N
build and rebuilt for M5+3.
It would be good to have the separate builds, but don't commit to
them for M5 if you're not sure to finish them.
The pivot model and library should be very easy to review and
demonstrate the value. I'm pleased with the library, but might
choose to flatten some of the dispatch call hierarchy. The pivot
model is about right but needs cosmetic shuffles to use UML 2.4 and
modularise the OCL packages. The CS-2-Pivot conversion may yet get a
significant simplification, particularly if Xtext 2.0 helps a bit.

Ed

Ed,
It looks promising :)
Our M5 milestones is targeted on Monday, the 7th in February... as
soon as the source code is aligned to Xtext 2.0.0 let me know it
to make our builds be feeded by Xtext nightly repository.
On the other hand, I'm currently involved in a project at work, so
my time to spend in Open Source projects gets again decreased. I
think that the releng is quite stable. Perhaps, I could spend some
time to improve the documentation concerning our public composite
repositories and minor hints concerning buckminster...
So, I could then either:
- Start the creation of different jobs to create different
artifacts/repositories for the MDT/OCL Core (our current SDK) and
MDT/OCL (our current examples).
- or, Start to review of the development stuff (Axel's patches,
pivot model, etc,... ).
In principle, we could survive without the MDT/OCL Core and Tools
split (as we have been doing so far). However as you know,
creating an stable repository at +1 with the examples depending on
Xtext could be risky. We should probably need to create nightly,
integration and stable builds using the Xtext nightly repository
to avoid surprises at +3 (and +4).
Best Regards,
Adolfo.

Hi Adolfo
Xtext moving to 2.0 at M5 will clearly break the current MDT/OCL
Examples, so remove the Xtext editors to avoid breaking the
Indigo integration unless...
A lot of things came together over the weekend.
I was able to start using the pivot-model based Xtext editors
to:
- edit constraints in the OCL standard library definition model
- see pivot-level semantic errors in the editor
- auto-generate the OCL Standard Library chapter pretty-printing
the constraints from AST models
Generally the branch now looks promising, so I'm about to
migrate to Xtext 2.0.0M4 and perhaps later nightlies and will
hopefully promote the branch just in time for M5. Flaky editors
will at least be better than no editors.
That gives us/me M6, M7 ... to fix the bugs. At least this year
we're bug fixing from M5, rather than starting development at
M6.

Ed Willink
-------- Original Message --------
Hi all,
for M5 we (Xtext) will promote the 2.0 stream to the indigo builds, which contains some API changes.
We would like to help any clients updating/migrating their code and would kindly ask to inform us if you use Xtext somehow.
I know the Ecore Tools do and we are already in contact with Ed Willink.
Are there any other projects consuming Xtext?
Best Regards,
Sven
