Examples

Reading JSON

fn main() raises:
 # Create a JSON object
 var o = JsonObject(
 '{"i64": 1000, "u64": 1000000000000000000, "b": true, "s": "Hi", "obj":'
 ' {"a": 100, "s": "hello"}, "arr": [1,2,3], "s_arr": ["a", "b", "c"],'
 ' "null": null}'
 )
 # Reading
 var i64 = o.get_i64("i64")
 var u64 = o.get_u64("u64")
 var b = o.get_bool("b")
 var s = o.get_str("s")
 # Reading nested object
 var obj = o.get_object_mut("obj")
 var obj_a = obj.get_i64("a")
 var obj_s = obj.get_str("s")
 # Reading array
 var arr = o.get_array_mut("arr")
 var arr_0 = arr.get_i64(0)
 var arr_1 = arr.get_i64(1)
 var arr_2 = arr.get_i64(2)
 # Reading string array
 var s_arr = o.get_array_mut("s_arr")
 var s_arr_len = s_arr.len()
 var s_arr_0 = s_arr.get_str(0)
 var s_arr_1 = s_arr.get_str(1)
 var s_arr_2 = s_arr.get_str(2)
 # Handling null value
 var null = o.get_value("null")
 var i64_2 = o.get_value("i64")
 # Printing results
 print("i64: ", i64)
 print("u64: ", u64)
 print("bool: ", b)
 print("string: ", s)
 print("obj.a: ", obj_a)
 print("obj.s: ", obj_s)
 print("arr[0]: ", arr_0)
 print("arr[1]: ", arr_1)
 print("arr[2]: ", arr_2)
 print("s_arr length: ", s_arr_len)
 print("s_arr[0]: ", s_arr_0)
 print("s_arr[1]: ", s_arr_1)
 print("s_arr[2]: ", s_arr_2)
 print("null is null: ", null.is_null())
 print("i64 is null: ", i64_2.is_null())

Writing JSON

fn main() raises:
 # Create a JSON object
 var o = JsonObject('{"a": {"b": {"c": 100}}}')
 # Get the nested object
 var a = o.get_object_mut("a")
 var b = a.get_object_mut("b")
 # Read the current value
 var c = b.get_i64("c")
 # Output the current value
 print("Initial value of c: ", c)
 # Write a new value
 o.insert_bool("f", True)
 o.insert_u64("g", 1000000000000000000)
 o.insert_i64("d", 101)
 o.insert_str("e", "hello")
 o.insert_array("h", JsonArray())
 o.insert_object("i", JsonObject('{"j": 100}'))
 # Get the updated object
 var a_2 = o.get_object_mut("a")
 # Print the string representation of the nested object
 print("Updated object a: ", a_2.to_string())
 # Print the string representation of the entire JSON object
 print("Updated JSON object: ", o.to_string())
