Re: I found program for AST generating

This is quite interesting - thanks! If you've tried it out I'd be 
interested in knowing what you think of the quality of the generated files.

Does it use the latest bison and C++ features?
Is it thread-safe?

Does it use the flex C++ lexer?

Are the generated data structures for the AST easy to use and extensible?

I saw some very small toy examples in the github repo - do you know if 
it's been used for any large or complex grammars?

For example, I asked about it here: https://lists.gnu.org/archive/html/bug-bison/2018-12/msg00008.html . Now I found solution to this problem: BNFC. https://bnfc.digitalgrammars.com/ . You write single concise input file and BNFC generates bison's .y file (which parses to AST) from it together with pretty-printer.
