(Xtext) 15 Minute Tutorial needs to be updated for version 2.2 [message #778796]

The existing 15 minute tutorial - extended for Xtext appears to still be at the 2.1 level. It includes references to the deprecated class org.eclipse.xtext.xtend2.lib.ResourceExtensions. From looking through other posts and searching the net, this appears to have been replaced by org.eclipse.xtext.xbase.lib.IteratorExtensions.

Using IteratorExtensions produces the error: Couldn't resolve reference to JvmType 'org.eclipse.xtext.xbase.lib.IteratorExtensions'.

This is in the first step of the tutorial and renders it useless for this release of Xtext.

After restarting Eclipse, the error for IteratorExtensions has gone away and the editor is now able to resolve the reference to it. I'm now able to continue with the tutorial by simply replacing the

import static extension org.eclipse.xtext.xtend2.lib.ResourceExtensions.*

with

import static extension org.eclipse.xtext.xbase.lib.IteratorExtensions.*

Hi David,

please open a bug report. This would get lost in the forum otherwise.

Regards,

I had to do this, to work:

package com.diegogusava.generator

import org.eclipse.emf.ecore.resource.Resource
import org.eclipse.xtext.generator.IGenerator
import org.eclipse.xtext.generator.IFileSystemAccess
import org.eclipse.xtext.naming.IQualifiedNameProvider
import com.google.inject.Inject
import com.diegogusava.myDsl.Entity
import com.diegogusava.myDsl.Feature

class MyDslGenerator implements IGenerator {
	
	@Inject extension IQualifiedNameProvider nameProvider 
	
	override doGenerate(Resource resource, IFileSystemAccess fsa) {
	
		for(e: resource.allContents.toList().filter(typeof(Entity))) {
			 fsa.generateFile(
                e.fullyQualifiedName.toString.replace(".", "/") + ".java",
                e.compile)
		}
	
	}
	
	def compile(Entity e) ''' 
        «IF e.eContainer != null»
            package «e.eContainer.fullyQualifiedName»;
        «ENDIF»
        
        public class «e.name» «IF e.superType != null
                        »extends «e.superType.fullyQualifiedName» «ENDIF»{
            «FOR f:e.features»
                «f.compile»
            «ENDFOR»
        }
    '''
    
    def compile(Feature f) '''
        private «f.type.fullyQualifiedName» «f.name»;
        
        public «f.type.fullyQualifiedName» get«f.name.toFirstUpper»() {
            return «f.name»;
        }
        
        public void set«f.name.toFirstUpper»(«f.type.fullyQualifiedName» «f.name») {
            this.«f.name» = «f.name»;
        }
    '''
	
}
