Thank you Christian, also using XpandFacade I keep having the same problem: the template definition is not found. I thought Xpand looked into the classpath for the templates (and my template is accessible through classpath) but it is not found. I got this error:
EvaluationException : No Definition templates::Template::formatParser for positionalParserDsl::Format could be found!
Internal error : element was null

I invoke XpandFacade in this way:
public void generate(Format format){
Output output = new MemoryOutput();
XpandExecutionContextImpl execCtx = new XpandExecutionContextImpl(output, null);
execCtx.registerMetaModel(new EmfRegistryMetaModel());
XpandFacade facade = XpandFacade.create(execCtx);
facade.evaluate("templates::Template::formatParser", format);
}

You have 3 potential errors:
1) Does your template definition look like?
«DEFINE formatParser FOR Format»
...
«ENDDEFINE»
2) If the template is in a source folder (that meas the folder is on the build path) then you must write:
facade.evaluate("formatParser", format);
3) You only register the standard EmfRegistryMetamodel. Where is your type (class or interface) Format defined?
Xpand needs to know this. If you have created your own metamodel you must register either the whole ecore file or each package (e.g. positionalParserDsl) that includes types you use in your code generation.
This can e.g. be done using the following code (assuming that positionParserDsl is your package):
EmfMetaModel metamodel = new EmfMetaModel();
String packageName = positionalParserDsl.class.getName();
metamodel.setMetaModelPackage(packageName);
execCtx.registerMetaModel(metamodel);
