Open an issue if you think you found a bug in JavaCC.
If you use version 8 and generate for Java, and you do not know to which part it is related (the base or the core or the generator), open it here in the generator;
same for C++: here;
same for C#: here.
If you are sure of the project it is related to, open it in the issues section of the project.
If you use version 7, open it here.
Create a new discussion (in the Discussions tab) if you have some general question - do not create an issue for a question.
But don’t hesitate to ask!
Contact the developers and community on the Google user group or email us at JavaCC Support if you need any help.
