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?

Hi. I long time ago I was interested in generating input files for bison (i. e. 
generating .y files) for producing AST. 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.
