I have an AST outputted for some Lua code by my grammar file, which currently does parsing and lexing for me. I want to add a tree grammar to this, but since i'm using C# i'm not sure how to do it. What's the basic process for generating tree grammar code when you already have a parser and lexer written? UPDATE: I have the following gra...
I'm finding myself challenged on how to properly format rewrite rules when certain conditions occur in the original rule. What is the appropriate way to rewrite this: unaryExpression: op=('!' | '-') t=term -> ^(UNARY_EXPR $op $t) Antlr doesn't seem to like me branding anything in parenthesis with a label and "op=" fails. Also, I've...

Why the method does exist in Java but not in C#? And why do they (the authors) advise to override the following methods: protected override void Topdown() { topdo...
