Dear all, I have a grammar for a fairly small and simple language that I have created for our project. Once every command in this language is parsed through this grammar, a Java object is returned. Everything is working fine.
Now, I have a requirement to read all the available rules/commands of the language (I am only interested in the command/rule names). In order to do so, I have been trying to get the AST tree working by adding options to my grammar for AST tree. For some reason, when I add these options to my grammar, I am getting compilation error complaining that my grammar rules cannot return any Java objects! Can I have commands/rules of my grammar return some Java objects and at the same time be able to build an AST tree off of my grammar? Is there an easy way to read these grammar command/rule names using antlr runtime API's? Any code sample out there that shows how do to the above (namely returning objects from grammar rules and building the tree at the same time)? Any help here would be greatly appreciate. _______________________________________________ antlr-dev mailing list antlr-dev@antlr.org http://www.antlr.org/mailman/listinfo/antlr-dev
