Eh, dkjson implements null as an object with a metatable function that encodes it back as “null”. Hopefully it’s considered equal to itself in comparisons.
Dkjson is fast enough for most scripting purposes. OTOH cjson’s userdata null is supported by some other libraries that deal with data structures.
Of course, there’s a problem then that various libs may have their own nulls, not equal to each other. There’s even a lib that tries to marry some of them.
Iirc I needed a json lib on Windows, or was just fed up with compiling things for some reason, and used dkjson instead of cjson. It turned out to be more than adequate, as is pretty typical for Lua-only code. Although it can use the LPeg lib to speed up parsing.
yeah that’s probably when you should drop down to C.

interesting! it should be equal since it’s always just a pointer to that same table.
I just never tried, so amn’t entirely sure.

yeah there’s a lot of regex in there so i definitely get wanting some compiled parts.
