[antlr-interest] current rule name

[Mark Volkmann]

Is there an easy way to determine the name of the rule that is
currently being processed? In my case I'm overriding the
getErrorMessage method in BaseRecognizer and need to know the current
rule name in order to create a good error message. I looked at the API
for RecognitionException and don't see a way to get the rule name. I
know I could use the "paraphrase mechanism" discussed in the book in
section 10.3, but I thought maybe there was an easier way.
