I worked for a long time to bastardize the ANTLR-based
refactoring project Transmogrify into doing what I
wanted, but eventually ran across the following set of
articles which basically convinced me that
Transmogrify was not as good a starting point as I
could find:


I then resolved to study and understand ANTLR before
attempting to tackle this problem.  At one point
Terence was tossing around the idea of having his grad
students implement something similar.  There seems to
be quite a demand for a powerful, versatile, Java
parsing package with AST and symbol table construction
that can be included in an IDE or used otherwise.  I
know Bogdan Mitu and probably others had worked on
incremental lexing/parsing, which would be a handy, if
not essential feature for such a package.  It all
seems like a fairly tall order.

Ter, do you have any comments about the articles I
mentioned above?  I may have asked before but I don't
recall whether the question may have been lost in the
