Hi, all. I've been working on translating the language our lab has created (Hop) to Java, and I keep hitting a wall. Has anyone had experience with the StringTemplate returned by getTemplate() being null? When I debug, st inside the tree returned by the tree grammar is null, and I can't figure out why. Is this because there's something wrong with the template? Any guesses?
I'm referring to code that, from Dr. Parr's books, looks like: Gen.prog_return r2 = walker.prog(parser.numOps, parser.locals); Above, the st in the start_return (or prog_return, or what is returned by the start rule) of r2 is null. And: StringTemplate output = (StringTemplate)r2.getTemplate(); System.out.println(output.toString()); Because st is null, the output is obviously null. My rules all seem to be syntactically correct. I don't understand... Any help, in certain or guess form, is appreciated.
