Scenario: I have a DSL in such a way that components can be distributed over multiple files. e.g. let say , I have foo.mydsl, bar.mydsl.

Now, I want to generate code for model composite of above mentioned files. I checked through the stub generated by xtext for standalone code generation, but it takes one resource at a time.

def protected runGenerator(String string) {
	// Load the resource
	val set = resourceSetProvider.get
	val resource = set.getResource(URI.createFileURI(string), true)
       // Validate the resource
	val issues = validator.validate(resource, CheckMode.ALL, CancelIndicator.NullImpl)
	if (!issues.empty) {

	// Configure and start the generator
	fileAccess.outputPath = 'src-gen'
	val context = new GeneratorContext => [
		cancelIndicator = CancelIndicator.NullImpl
	generator.generate(resource, fileAccess, context)
	System.out.println('Code generation finished.')

Now, this code fails for me, because foo.mydsl has some component dependency in bar.mydsl. I want to read all dsl files in a given folder and generate the code ?

Also, if I pass folder path to the above mentioned generator, then it throws "Cannot create a resource for 'file:/tmp/dsl/'; a registered resource factory is needed" ?

you need to load all resources manually e.g.

val resource = set.getResource(URI.createFileURI(string), true)
val resource2 = set.getResource(URI.createFileURI(string2), true)
val resourceN = set.getResource(URI.createFileURI(stringN), true)

or traverse the file tree etc ..

Need professional support for Xtext, Xpand, EMF?
