[Xtend] Increase a postfix in a for loop [message #686014]

Hello,

In my Xtend file, I have something like this:

«FOR variable : entity.variables»
   MyVar var;
«ENDFOR»

Now, I would like to add a unique postfix to all var variables (ideally an increasing number).

Is there a way to do this ? In Xpand, I think you could achieve that by using the ITERATOR keyword (never tried it, so I'm not sure).

Thanks,
Cédric

Hi,

I have a similar problem. Did you find a solution for that?

I actually wish something like this:

def callBla()'''
   «repeatBla»
   ...
   «otherstuff»
'''

def repeatBla(){
   var i = 0
   while (i <5){
      i.bla
      i=i+1
   }
}

def bla(Integer i)'''
   «i»bla 
'''

Thanks,
Carmela

Hi Carmela,

in your case the solution is easy

'''
«FOR i : 1..5»
«i»bla
«ENDFOR»			
'''

In Cédrics case its a bit more to do / work arround

'''
«FOR i : list.index»
«i.key» «i.value»
«ENDFOR»
'''

	def <T> index(Iterable<T> i) {
		val Map<Integer, T> map = <Integer, T>newHashMap()
		var counter = 0
		for (T e : i) {
			map.put(counter, e)
			counter = counter+1
		}
		val Set<Map$Entry<Integer, T>> res = map.entrySet
		res
	}
