Anonymous class and namespace are authorized by this two rules. But it is a problem for the filters. Make 2 filters, one to put a name and another to delete it. ClassKey Identifier? BaseClause? -> ClassHead "namespace" "{" NamespaceBody "}" -> UnnamedNamespaceDefinition You can put a invalid name to find them easily when deleting them (e.g. using '<concat-strings>["#",<new>]' and 'where(explode-string;[35|id])'). Tell me when you are starting it. -- Valentin David valentin(a)lrde.epita.fr

You can access our subversion repository: http://svn.lrde.epita.fr/svn/transformers/trunk The directories are independant sub-projects, and the "bundle" sub-project builds the whole transformers tarball. > I've applied the necessary fixes to the latest sources of StrategoXT and > 0.1 now runs fine :) . The check is ok and examples that don't use > iostream can be parsed with parse-cxx. Looks promising! We really appreciate the feedback. Transformers 0.1 was released in order to get more people interested in the project. Hopefully 0.2 will provide a more usable parser.
