Re: [incquery-dev] New Xtext - Xbase is becoming API
|
Hi all,
I have some good news, and bad news and some ugly...
The good: I managed to update the IncQuery language to work with Xtext 2.7. The updated API is nice, it is much easier to read and manage than the previous iteration. And I got rid of almost all non-API calls.
The ugly: it required a near-complete overhaul of the model inferrer. In other words, there is no way I am going to backport these changes to 0.8.1.
The bad: the Xcore integration extends XcoreBatchScopeProvider that got removed from the latest Xcore version. To tell the truth, I have no idea why was it used and how it should be updated to work with Xtext 2.7...
I created two Gerrit changes related to all this work. 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.
Type provider rewrite: https://git.eclipse.org/r/#/c/33019/
Xtext compatibility change: https://git.eclipse.org/r/#/c/33020/
There are some test failures related to these commits that I am trying to fix shortly; I am open to ideas about the Xcore integration...
Cheers,
Zoli

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.
