Problem Implementing linking-scoping [message #645398]

I've a problem (Im a newbie) implementig a scope provider for this example grammar:

/*****************************************/
Program:

ports+=port*

main=main;

port:

{port} "inputPort"|"outputPort" name=ID portBody=PortBody;

PortBody:

"{" "Operation" ":" name=ID "}";

main:

{main} "{" opCalls += opCall* "}";

opCall:

op=[PortBody] "(" INT ( "," INT)* ")";

/*****************************************/

How can I implement my scope provider to make the linking mechanism working in my grammar (e.g I wold link sum in the snippet down here)

inputPort pt1{

Operation: sum

}

main {

sum(1,2)

}

Hi,

The short answer is: The linking/scoping works out of the box, provided you use the SimpleNameFragment instead of the QualifiedNameFragment (search this forum or the documentation).
Right now, the name used for "sum" is pt1.sum (qualified name calculated using the names of the containers as well).
