Relax, PNACC 2 is not another compiler compiler.
That said, it is a parser generator tool, somewhat similar to yacc or bison.
But also quite different. Mostly much simpler.
It takes a simple grammar description like so:
expr -> expr + term
expr -> term
term -> term * atom
term -> atom
atom -> - atom
atom -> ID
atom -> ( expr )
Put is in a file example.grammar and then run:
pnacc2 example.grammar -o example.json
This will create JSON file example.json.
