Convert given Lua data into a JSON string.
This function recursively converts the given Lua data into a JSON string,
ignoring any unsupported data. Lua tables are converted into JSON arrays if they
only contain integer keys, mixed tables are turned into JSON objects with any
existing numeric keys converted into strings.
Lua functions, coroutines and userdata objects are ignored and Lua numbers are
converted to integers if they do not contain fractional values.
Parameters
- data: The Lua data to convert, can be a table, string, boolean or number.
- pretty: A boolean value indicating whether the resulting JSON should be pretty printed.
Usage:
json = luci.jsonc.stringify({ item = true, values = { 1, 2, 3 } }) print(json) -- '{"item":true,"values":[1,2,3]}'
Return value:
Returns a string containing the JSON representation of the given Lua data.See also:
