@ -1530,7 +1530,16 @@ minetest.parse_json(string[, nullvalue]) -> something
^ nullvalue: returned in place of the JSON null; defaults to nil
^ On success returns a table, a string, a number, a boolean or nullvalue
^ On failure outputs an error message and returns nil
^ Example: parse_json("[10, {\"a\":false}]") -> {[1] = 10, [2] = {a = false}}
^ Example: parse_json("[10, {\"a\":false}]") -> {10, {a = false}}
minetest.write_json(data[, styled]) -> string
^ Convert a Lua table into a JSON string
^ styled: Outputs in a human-readable format if this is set, defaults to false
^ Un-serializable things like functions and userdata are saved as null.
^ Warning: JSON is more strict than the Lua table format.
1. You can only use strings and positive integers of at least one as keys.
2. You can not mix string and integer keys.
This is due to the fact that Javascript has two distinct array and object values.
^ Example: write_json({10, {a = false}}) -> "[10, {\"a\": false}]"
minetest.serialize(table) -> string
^ Convert a table containing tables, strings, numbers, booleans and nils
into string form readable by minetest.deserialize
