I'm in need of two solutions: 1. Generating a language model out of ANTLR grammar. Preferably in C#. 2. Printing an AST to text according to an ANTLR grammar. I found this https://github.com/miho/VMF-Text, but anything else?

wow ANTLR in c#, that takes me back a while. I don't have any recommendations but a starting point: Look through the top N contributors in the antlr repo, track down any blogs or other projects they've written about or committed to. It seems likely they would have had some of these need as well

thanks, not a bad idea! 🙂
