generation with two dsl [message #653331]

hello

I created two DSL 'metarepDSL and repoDSL)
repoDSL can use elements declared in a .metarepDSL file.
but metarepDSL don't need another dsl.

I have two generation for repoDSL, they work.
but for the generation of metarepDSL I have sometimes (not everytime) this message :

1 error:
	b.repoDSL - /home/jeremie/tocea/EclipseProjects/com.tocea.xtext.repository.launch/testRule/b.repoDSL
		3: Couldn't resolve reference to Rule 'metarep.r1'.

	at org.eclipse.core.internal.jobs.Worker.run(Worker.java:54) [org.eclipse.core.jobs_3.5.1.R36x_v20100824.jar:na]

so the generator read files repoDSL.. it should not do that.

mt workflow look like that :

module workflow.MetarepositoryDSLGenerator

import org.eclipse.emf.mwe.utils.*

var targetDir = "src-gen"
var fileEncoding = "UTF-8"
var modelPath = "src/model"

Workflow {

	bean = StandaloneSetup {
		registerGeneratedEPackage = "com.tocea.emf.metaRepository.model.metaRepository.MetaRepositoryPackage"
		registerGeneratedEPackage = "com.tocea.emf.metaRepository.model.repository.RepositoryPackage"
	}
	component = org.eclipse.xtext.mwe.Reader {
	// lookup all resources on the classpath
	// useJavaClassPath = true

	// or define search scope explicitly
		path = modelPath

		// this class will be generated by the xtext generator 
		register = com.tocea.dsl.MetarepositoryDSLStandaloneSetup {}
		load = {
			slot = "metaRepositories"
			type = "MetaRepository"
		}
	}

	component = org.eclipse.xpand2.Generator {
		expand = "templates::Template::main FOR metaRepositories"
		outlet = {
			path = targetDir
		}
		fileEncoding = fileEncoding

thats strange that this error is not launch everytime.

regards,

Jérémie

In fact,

If I launch the generation for the repoDSL files before the generation for metarepDSL files, it works.
It failed if I launch the generation of metarepDSL first.

Hi,

shouldn't you call both standalonesetups in your workflow:

register = com.tocea.dsl.MetarepositoryDSLStandaloneSetup {}
register = com.tocea.dsl.OtherDSLStandaloneSetup {}

maybe.

but I have repoDSL wich dependsod metarepDSL but I don't want that metarepDSL depends of repoDSL.

I will have later to add other language wich will use metarepDSL. I dont want for each language to add

register = com.tocea.dsl.OtherDSLStandaloneSetup {

in metarepDSL.

I want metarepDSL insdependant

Regards,

Jérémie

Hi,

sorry i thought it was the other way round, but why does your metarepository dsl generator then try to read .repoDSL files?

one reason might be that workflows are not thread safe but you use them with the jobs framework.

Update:

Another point is that it is a bad idea to call

register = com.tocea.dsl.AnyDSLStandaloneSetup when the workflow is started from within eclipse sice this may kill some ecore / xtext registries.

I really don't know why the generator try to read .repoDSL files.

"one reason might be that workflows are not thread safe but you use them with the jobs framework"

I don't really understand that but maybe you right.
I fight I don't really use the workflow as descibe before. I translate this workflow in java.
(because i need to work in no standAlone. ).

So maybe I have to add something in my java code.

What can I do to make my code thread safe?

I dont really understand the link between the fact to be thread safe anf my problem that the generator read .repoDSL files

I forgot, these two dsl use the same ecore model file

Hi,

the reader reads all files it knows. maybe you can try to configure it filtering. and you should remove the register stuff from the workflow.

Yess

It seams to work Smile

.

I add that in the workflow :


import org.eclipse.xtext.mwe.*

omponent = org.eclipse.xtext.mwe.Reader {
	// lookup all resources on the classpath
	// useJavaClassPath = true

	// or define search scope explicitly
		path = modelPath
		uriFilter = NameBasedFilter {
			extension = "metarepDSL"
		}
}
....

thanks Christian
