Re: [incquery-dev] New Xtext - Xbase is becoming API

[Ujhelyi Zoltán <ujhelyiz@xxxxxxxxxx>]

Hi,

some additional info: Xcore 1.2.1 (that will be released for Luna SR1 on the 26th September) should be compatible with Xtext 2.7.0 - see https://www.eclipse.org/forums/index.php?t=msg&th=805897/ for details.

The bad news is, until that point, we won't be able to generate the sources of the rete recipes bundle in the Maven build (or at least until the xcore plug-ins are not pushed to a Maven repository...).

Cheers,
Zoli

The first relates to a cleanup of our Type Provider implementation (basically, disconnecting it from Xtext API, and providing something other languages can also reuse); the second is the Xtext version update. The first is a prerequisite of the second because Xtext 2.7 also removed base classes we were using previously.

There is a change that I hope will benefit us greatly in the long run: https://www.eclipse.org/Xtext/releasenotes.html#inferrer_api - the model inferrer API is becoming stable. I don't know, how much of Xbase is API now, but this is something I like very much to hear... I guess, the master (0.9) branch should require this new version as soon as possible.
