JSON AppendArrayCopy Example

Demonstrates the AppendArrayCopy function.

Note: This example requires Chilkat v9.5.0.82 or above.

Zig

const std = @import("std");
const chilkat = @import("chilkat");

pub fn main(init: std.process.Init) !void {
    const alloc = init.arena.allocator();

    const json = try chilkat.JsonObject.init();
    defer json.deinit();
    json.load("{ \"name\": \"John\", \"marbles\": 100 }") catch {};

    const jarr = try chilkat.JsonArray.init();
    defer jarr.deinit();
    jarr.load("[ 1, 2, 3, \"apple\", \"orange\", [ 10, 20, 30 ], { \"name\": \"Alfred\"} ]") catch {};

    // Copy the contents of jar to a new array member named "stuff".
    json.appendArrayCopy("stuff", jarr) catch {};

    std.debug.print("{s}\n", .{try json.emit(alloc)});
    // Expected output is:  {"name":"John","marbles":100,"stuff":[1,2,3,"apple","orange",[10,20,30],{"name":"Alfred"}]}

    // Note: The contents of the array were copied.
    // If we modify the contents of jarr, it does not modify the array contained within "json" because it is a separate copy.
    // For example:
    jarr.addIntAt(-1, 2020) catch {};
    std.debug.print("{s}\n", .{try jarr.emit(alloc)});
    // Expected output: [1,2,3,"apple","orange",[10,20,30],{"name":"Alfred"},2020]

    std.debug.print("{s}\n", .{try json.emit(alloc)});
    // Remains unchanged: {"name":"John","marbles":100,"stuff":[1,2,3,"apple","orange",[10,20,30],{"name":"Alfred"}]}
