Arsène von Wyss released an
implementation of the Engine allows the developer to map a semantic
action classes directly to the grammar's terminals or reductions. The
result of this approach is the creation of a functional semantic AST
without the intermediate token-based AST representation.
von Wyss provided a helpful
"how-to" guide for using the BSN Engine. It includes
documentation on how to use the Engine, installation instructions, and
requirements.
