I think you're missing the errors that the lexer should be 
printing to the console :)

You haven't defined a lexer rule that can match an arbitrary 
sequence of characters (or just letters), so it won't be able to 
generate a token for them.

Remember, the lexer runs first (and by itself), and must 
completely convert the input text into a token sequence before the 
parser can figure out what it actually means.
