yes, it was pretty obvious, just wanted an excuse to put a grin today
but, if you want to learn, just do all three:
1: parser->C structs->Lua. you'll find lots of references, work
should be straightforward
2: write to Lua structs directly within the parser. did you know that
even without the language, Lua is a nice data structure library?
3: LPEG. in most cases, the data flow in a LPEG parser works just like 2
I'd advise doing it in this order, because once 1 is running going to
2 is mostly removing code, and going to 3 is mostly syntax and some
extra code deletion.
