Hello Jim,
Thank you very much.
I did not know how to deal with these methods.
Following your advice my rule is now:
repeat
@init{ int mark_before; }
:
^(REPEAT a = atom {mark_before = input.mark();} list = . )
{ for (int i = 0; i < $a.r ; i++) {
input.rewind(mark_before);
list_instructions();
}
input.rewind(input.index() + 1);
// need to skip one node to reach the right position
}
;
Claude

Should you not be using the push(index) and pop() of the
CommonTreeNodeStream or mark() and rewind()? The index() method will
give you the current location when you hit the node that you want to
repeat.
