@Inject
protected void setInjectedParser(IParser parser) {
this.parser = parser;
}

I want to manually run the xtext engine and i'm not sure when and where the setInjectedParser is being called.

thanks,

Just make sure the class is created with Google guice. E.g. by
calling new mydslstsndalonesetup().createinjectoranddoemfregistration
if the code is called stsndalone

=>

Injector i = new MydslStandaloneSetup().createInjectorAndDoEMfRegistration()
MyClass c = i.getInstance(MyClass.class)

P.S: a bit more context in such questions would be helpful

Ok thanks!

I will try to explain
I have my dsl as plugin.

i want to create a new app that use my dsl
so i tried to write this code:
JsonParser p = new JsonParser();
IParseResult r = p.parse(new StringReader("{}"));
//once that work it will be the file data instead of {}

but when i do the parse the node model builder is null and the following line has exception:
return doParse(ruleName, in, nodeModelBuilder.get(), 0);

and i'm not sure how to init nodeModelBuilder

i'm sure i missing some steps but i'm not quite familiar with the xtext process.
