[Xpand/Xtend 1] What future can Xpand/Xtend expect? [message #755540]

Hi,

Xtend2 is a young, but already a popular language. My congratulations to
the Xtend2 team with this success.

However, Xtend2 lacks some features that were available in old good
Xtend. For example, it's very difficult to use Xtend2 for M2M and M2T
transformations of dynamic EMF models or UML Profiled models, while
pluggable type system of Xtend1 made it quite easy. That's why it's
natural to ask what can we expect from Xtend1/Xpand1 in the future.

Are you going to implement new features?
How actively are you going to fix existing or newly reported bugs and
enhancements?
How many developers are going to work on this project?
For how many releases do you expect Xpand/Xtend1 to be a part of Eclipse
release train?

Any information regarding the future of Xpand/Xtend would be appreciated
by me and other people who used the old Xpand/Xtend for model to model
or for model to text transformations.

Thanks,

Hi Tatiana,

these are valid questions, indeed. We can expect Xtend2 to close the gaps that Xpand/Xtend left in mid-term. The Xtext team has to answer this.

For Xpand the planning is to keep maintenance up some time in the future. It is not planned to implement sophisticated new features in mid-term, more to fix stabilizing or performance bugs, and keep documentation valid.

Xpand would need a major refactoring with breaking API changes to really move forward. For this there are currently not enough resources available.

Xpand will be on the Juno release train, and we can expect this for at least 2 more generations.

That's from my side.

Thanks for your response Karsten.

That's good news, do you think it worth filing these issues in the
Xtend2 bugzilla to keep track of them?

I am glad to hear that Xpand will be with us for several more releases.

Thanks and regards,
Tanya.

I'm sorry, but I have to say that we don't plan to add support for a
pluggable type system in the near future.
