What I miss in the book is more details and more clarity as to the nature and power of the parser generating algorithm. I would be glad to read more about e.g. :

  1. Is ANTLR capable of generating a parser for every LL(k) grammar? Or for every strong LL(k) grammar? Or for some other class of LL(k) grammars?
  2. How does ANTLR handle lookahead of more than 1 symbol?
  3. Are there limitations to ANTLR LL(*) other than the lookahead language being regular? If yes then what?
  4. What are the limitations to use of recursion in lexer rules?

Regards Nikolay
