Xbase: Organize imports removes imported model packages [message #1602305]

Hi,

In a simple Xbase language (like Domainmodel example) I would like to reference plain DSL (EMF) objects defined in other DSL model files.

Importing using

import mypackage.*

works, but yields a warning

- The use of wildcard imports is deprecated.

Also the import statement get removed during organize imports Sad

My question is, how can I import and reference plain DSL objects (without corresponding inferred Java-classes) defined in different files?

Thank you!

Cheers,
Boris

PS
By the way, is it correct, that I also have to import my own package, like

package org.test
import org.test.*
....

Hi Boris,

Xbase's XImportSection is designed and implemented to allow imports of
JvmTypes. Other objects are not taken into account. Please take a look
at Xcore's specialization to see how to deal with DSL concepts.

Best,
Sebastian

Hi Sebastian,

thank you! I had suspected that...

And what about imporing own package?

Two files

package a

Object X1

and

package a

Object X2 {
  val X1 x1
}

produces #["a.X1", "a.X2"] in the global scope. But referencing X1 from X2 searches only for "X1" and finds nothing.

Shouldn't object's own package be auto-imported like in Java?

Cheers,
Boris

Hi Boris,

generally yes. Is 'X1' in 'val X1 x1' implemented by a JvmTypeReference
and is the value properly put into a type with the package name 'a'?

Best,
Sebastian

Hi Sebastian,

Ah, it should be JvmTypeReference? It's a Plain Old EMF Object... I guess, I have to implement this auto-importing myself.

Thank you!

Cheers,
Boris

This great Advanced Xtext Manual has very detailed explanations for the underlying conepts.
