Dear all.

Is there a plan to support an expression similar to the Java try-with-resources in the Xbase layer?

If not, is there a tutorial that explain how to create new XExpression (with the type, the Java generator, etc.)?

All the best.
Stéphane.

Yes, in the second edition of the book there's an example for extending Xbase, the type system and the compiler.

Concerning try-with-resources, I've implemented that feature in Jbase, https://github.com/LorenzoBettini/jbase (in particular, this is the PR implementing that https://github.com/LorenzoBettini/jbase/pull/60).

I was not aware of the bug for Xbase for try-with-resources, and now I plan to work on that! Smile
