JSON Iterate Members

See more JSON Examples

Demonstrates how to loop over the immediate members of a JSON object. 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();

    const json_str = "{ \"id\": 1, \"name\": \"A green door\", \"tags\": [\"home\", \"green\"], \"price\": 125 }";

    json.load(json_str) catch {
        std.debug.print("{s}\n", .{try json.getLastErrorText(alloc)});
        return;
    };

    const num_members = json.getSize();
    var i: i32 = 0;
    i = 0;
    while (i < num_members) : (i += 1) {
        const name = try json.nameAt(alloc, i);
        const value = try json.stringAt(alloc, i);

        std.debug.print("{s}: {s}\n", .{ name, value });

        const i_value = json.intAt(i);
        std.debug.print("{s} as integer: {d}\n", .{ name, i_value });
    }

    // Note: The StringAt method returns the value as a string regardless of the type.
    // If the value is a JSON array (such as for ["home", "green"]), then the JSON encoding
    // of the entire array is returned.

    // The IntAt method returns the value as an integer.  If the value does not convert to
    // an integer, then 0 is returned.
