I prefer table-driven approach to generators.

You might find a table-driven parser in simple components:

   http://www.dmitry-kazakov.de/ada/components.htm#Parsers_etc

which I am use for the only complex stuff, expressions. In almost any

descent parser. (I never managed to understand what formal grammars are
good for... (:-))
