Hi all, I have a similar issue using the C# target. Using the Cymbol.g example of pattern 17 Symbol Table for Nested Scopes of the Language Implementation Patterns book I could not get it to work because there is now downup method. According to the documentation this method walks the AST code using ANTLR's built-in downup( ) strategy.
Am I correct assuming that this has not been implemented yet for the C# target (as Jim implies in his response). Is it difficult to implement it myself? I guess it would involve implementing the tree pattern matching stuff. Marc P.S. Hope this email files under the proper subject thread, and apologies in advance if it isn't (Just subscribed to the mailing list but I could not find out how to get previous posts from it) > Pattern matcher or normal tree walker?
