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

[Ujhelyi Zoltán <ujhelyiz@xxxxxxxxxx>]

Hi,

so far there is no ticket available (but it seems we will need it...); the mentioned Gerrit change contains everything I have created so far for this migration.

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.
