Cross Referencing Problem [message #1355134]

I want to create xtext grammer for the below syntax

System simple_sys {
Component talker {Port t_port}
Component listener {Port l_port}
Connector pubsub {
Roles { publisher subscriber}
}
Attachments {
talker.t_port to pubsub.publisher
listener.l_port to pubsub.subscriber
}
}

How do I use cross referencing mechanism to refer, for eg, talker.t_port, pubsub.publisher, etc.

Any help much appreciated.

Hi,

xxxx=[Port|QualifiedName]

....

QualifiedName: ID ("." ID)*;

should do the trick

Attachments:
'Attachments' '{'
(attach += Attach)*
'}'
;

Attach:
source = [Port] 'to' target = [Role]
;

I used the above grammar, but how do i refer to ports which is in the scope of component or Role which is in scope of Connector.

I am quite new to xtext Smile
