What it is

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.
