I need a tool/lib to generate UML diagrams from source of a custom programming language grammar. Is there a tool with API or another method to relatively easily tell to generator how it should to interpret the grammar. I have full control of the programming language lexer.
Ask to specific clarification if you have some doubts.
Looks like a plain AST visitor should do, shouldn't it? Assuming that you have classes, interfaces, and attributes in your language, that should be easy to handle.
Proper layout of a diagram is a different issue, and can be done afterwards.
The reverse engineering of a language into an UML diagram is really a very long and difficult job. If you don't have 12 months research project and deep knowledge of programming and UML then it is better to use an existing tool.
