Hi,


Is there any consenus as to which is the best Java-producing parser
generator?


>From what I've read and tried so far it seems that:


Sable has these good points:
      - Bottom up
      - Action code in separate class
      - Don't have to generate tree
      - elegant error handling
      - GNU
but these bad points:
      - Very strict AST (seems to defeat the whole point of bottom up parsing)
      - how can you do semantic checks on the fly? e.g declaration before use?


JavaCC ::= <Good Points>*
      - Flexible tree building
      - popular
(Bad Points)+
      - Top-down
      - Proprietry


Note on javacc: I downloaded the latest release (v2.0), but the jjtree
preprocessor doesn't seem to work properly. It makes references to a
method setName(..) which it never includes in the nodes it
generates. This only happens in MULTI mode.


Haven't touched CUP.. Is it good?


GMD Suite seems pretty powerful, but it's a combination of a whole lot of
fiddly tools. It does allow arbitrary tree construction though, and it is
bottom up.


What does everyone think?


Regards,


Roger
