Auto format Xtext textual model [message #1858651]

Hi,
I am using Java to generate a textual model. While I have defined a custom formatter, the generated files are not automatically formatted. I have to do that manually. Is there a way I can do that automatically in Java for instance?

Is there a reason you don't create the model as ast programmatically?

Igöf you have text you need to parse it before you can format it

After selecting the elements that I want from the source model I use the following method in order to create the new file:

private static void save(Element element, ResourceSet resourceSet) throws IOException {
		Package n_p = MyPackageFactory.eINSTANCE.createPackage();
		n_p.getPackagedElement().add(EcoreUtil.copy(element));
		Resource n_r = resourceSet.createResource(URI.createURI( element.getName() + ".text"));
		n_r.getContents().add(n_p);
		n_r.getResourceSet().getResources().add(n_r);
		n_r.save(null);
	}

this is easy

n_r.save(SaveOptions.newBuilder().format().getOptions().toOptionsMap());
