Hi Everyone,
As a newbie working through my first real antlr project I find myself
wondering what is the
better way to keep track where I have been as I make my way through the
parser rules.
I am using a Java.g file and when I wind up for instance, down in the
statement rule, I would
like to be able to figure out how I got there. I have seen examples in the
reference book that
use boolean flags and scopes to do this. Is there a better way? Return
values on the rules?
Thank you,
Will T.
