Hello,
I'm having a problem converting a grammar to a tree grammar.
The grammar rule I need to translate is:
nonzeros : MYNZTN+ -> ^(MYNONZEROS MNZTN)+
;
I translated the above rule in my tree grammar as:
nonzeros: ^(MYNONZEROS MNZTN)+
;
When I translate the above rule in my tree grammar, ANTLR 3.0
complains that the + is an unexpected token. I would rather keep the
rule the way it is above. If I have to change it, I have to change
other rules in the tree grammar.
Is the problem I'm runing into a feature?
thanks in advance!
