Hi This is my grammar.
Query:
(key=Greeting)? (to=GroupTo)? from: Name
Greeting:
keyword='hello'
;
Name:
name=ID
GroupTo:
group+='and' name1=Name (','name1+=Name)*
;
I am trying to understand sentences like
hello john and jim from: tim
In the doGenerate method I want to retrieve the names only in GroupTo category. I am unable to take these name under one variable.
Instead of using name1 and name2 .I wish to use one variable to get all the names under Group.
var groupToNames =resource.allContents.filter(typeof(GroupTo)).map[name1].toIterable
How can I use one variable such that all Names under GroupTo is captured and I do not have to use name1 and name 2.
Is there a better way to represent the grammar or the retrieval in doGenerate method.
Also , I see that I cannot use the "to" variable to map.
Am I missing something.?

Basically you might want something like this:
GroupTo:
group+=Name ('and' group+=Name)*;
This will collect all member names in the collection-valued attribute 'group'. I'm not sure where exactly you want to have the ',' keyword as it is not mentioned in the concrete example.

Thank You for this.
GroupTo:
group+=Name ('and' group+=Name)*;
I wish to understand ,how can I add another category in the same rule.
For example I want to match
Australia and Jim
Jim and Australia
Australia and Australia
Jim and Jim
So ,in summary
I wish to match "COUNTRY/NAME and NAME/COUNTRY" in any order.
