Hello all,
I am relatively new in xtext so apologize if this is a stupid question. This problem is puzzling me for a few days now.
I am trying to enforce some rules on various elements in a rather generic way e.g. all reference lists should not suggest items they already include, a validation should also check this etc.
Using the reflective ecore API has put into a lot of problems. So the problem maybe the fact i don't fully understand it. So any suggestions about material to help me understand that API would be welcome (e.g. tutorials on how to use it or explanations of what the main classes are and how they are used would be more than appreciated - i i went through javadocs but it seems i am missing some kind of improtant detail)
now to my example.
I am trying to filter the existing scopes suggestions in all reference lists so they don't include elements already in the list. Unfortunately i am getting a cyclic exception. Note that i have tried the filtering through contentassist but it is even more difficult there because i can't figure out how to get the reference to the existing list in a consistent/elegant way.
The grammar
grammar org.xtext.example.mydsl.MyDsl with org.eclipse.xtext.common.Terminals
generate myDsl "http://www.xtext.org/example/mydsl/MyDsl"
Root:
packs +=Package*
;
Package:
"package" name=FQN "{"
elements+=Element*
"}"
;
Element:
{OneElement} "element" name =ID ';'|
{ManyElements} "elements" list+=Element* '#'|
{RefElements} "refs1" item+= [Element|FQN]* '!'|
{RefElements2} "refs2" item+= [Element|FQN]+ '!'|
{RefElements3} "refs3" item+= [Element|FQN]* '!'
;
FQN: ID ('.' ID)*;
class MyDslScopeProvider extends AbstractMyDslScopeProvider
override IScope getScope(EObject context, EReference reference) {
val current_scope = super.getScope(context, reference)
if(reference.isMany)
{
val ref_object = context.eGet(reference)
val ref_object_list = ref_object as EList<EObject>
if(ref_object_list.length>0)
{
val new_scope = new FilteringScope(current_scope, [!ref_object_list.contains(EObjectOrProxy)])
return new_scope
}
}
return current_scope
}
The sample model
package A
{
element Elementa1 ;
element Elementa2 ;
elements
element Elementa3 ;
element Elementa4;
elements element Elementa6 ; #
#
refs1 Elementa1 Elementa1 !
refs2 Elementa3 !
refs3 Elementa2 Elementa4!
element Elementa5;
}
