It is my pleasure to announce xtc and Rats!, version 1.12.0. Highlights include:

Support for parse trees, which are generated from the same grammars and processed with the same visitors as regular ASTs, thus facilitating source refactorings that preserve all formatting.

Support for Java 5, including grammar, pretty printer, and concrete syntax.

An improved Java 1.4 AST, which is compatible with the Java 5 AST.

Improved support for type-checking C and Java 1.4 ASTs.


Enjoy at http://cs.nyu.edu/rgrimm/xtc/.
