JSON library for gopher-lua in PeerDB
Unfortunately existing JSON libraries for gopher-lua suffer from the existing issue of how to encode an empty table, while this library offers a mechanism to specify how a particular table should be encoded if empty
These libraries also fail to integrate with UserData, which PeerDB scripting relies on heavily
gluajson exports encode & decode
To guide encode, there are 3 wrapper functions: array, object, raw
array / table can be used to direct whether an empty table should be encoded as an array or a table
json.raw(string) will interpolate string without encoding,
this can be useful if you want to wrap an already encoded json string into another json object
Passing true as the 2nd parameter to decode will decode json using markers,
arrays will be marked as array,
objects marked as object,
numbers marked as raw strings of their digits to preserve precision,
& nulls marked as raw("null")
To handle marked objects, there is a function unmark which for marked objects returns inner, wrapper,
while for unmarked objects the original parameter is returned
