[Xtend2] Code Reference [message #696542]

Hello,

i have some questions with regard to Xtend2.
Iam working with xtend2 since 2 weeks and there are some syntax problems for me.

First of all is there any kind of Code Reference oder complete Syntax explanation for Xtend2? I haven't found something yet.

I try to write an *.xtend file for my DSL.
In the DSL i have defined an enum Type, which i want to use in the Generator.xtend file. I just want to use a switch case statement or IF statements to check the different alternatives of my enum type.

What is the right syntax for importing my enum type into the Generator.xtend file?
What is the right syntax for a switch case statement over my enum type in xtend2?

...

«FOR x : model.elements»
«switch (x.type){
case enumtype1 : { printenum1(x) }
case enumtype2 : { printenum2(x) }
}

printenum*(x) are methods i want to invoke, when the specific enumtype is given.
The syntax posted above is absolut false, but where are the mistakes?

thanks,
greetings Marcel

Hi,

this works for me

Model:
	greetings+=Greeting*;
	
Greeting:
	'Hello' name=ID land=LND '!';
	
enum LND:
	BW | BY | NRW
;

	def generate(Model m) 
		'''
			«FOR g : m.greetings»
				«g.name» = «switch (g.land) {
						case LND::BW : "Baden-Wuerttemberg"
						case LND::BY : "Bayern"
						
					}»
			«ENDFOR»
		'''
