Json in OpenSCAD

OpenSCAD doesn’t have built-in JSON support or complex data structures like Go does. However, we can simulate some of the concepts using OpenSCAD’s available data types and functions. Keep in mind that this is a very limited representation and doesn’t fully capture the functionality of JSON in Go.

// OpenSCAD doesn't have built-in JSON support, so we'll simulate some concepts

// Simulating basic data types
function boolean_value() = true;
function integer_value() = 1;
function float_value() = 2.34;
function string_value() = "gopher";

// Simulating arrays and objects using lists and lists of lists
function array_value() = ["apple", "peach", "pear"];
function object_value() = [["apple", 5], ["lettuce", 7]];

// Simulating a struct-like object
function response(page, fruits) = [page, fruits];

// Main function to demonstrate the concepts
function main() = 
    let(
        bool_val = boolean_value(),
        int_val = integer_value(),
        float_val = float_value(),
        str_val = string_value(),
        arr_val = array_value(),
        obj_val = object_value(),
        res1 = response(1, ["apple", "peach", "pear"]),
        res2 = response(1, ["apple", "peach"])
    )
    [
        bool_val,
        int_val,
        float_val,
        str_val,
        arr_val,
        obj_val,
        res1,
        res2
    ];

// Execute main function and print results
result = main();
echo(result[0]); // true
echo(result[1]); // 1
echo(result[2]); // 2.34
echo(result[3]); // "gopher"
echo(result[4]); // ["apple", "peach", "pear"]
echo(result[5]); // [["apple", 5], ["lettuce", 7]]
echo(result[6]); // [1, ["apple", "peach", "pear"]]
echo(result[7]); // [1, ["apple", "peach"]]

This OpenSCAD code demonstrates:

Simulating basic data types (boolean, integer, float, string).
Representing arrays using OpenSCAD lists.
Simulating objects using lists of lists (key-value pairs).
Creating a simple struct-like object using a function that returns a list.
A main function that creates and returns various data structures.
Echoing the results to simulate printing to console.

To run this code:

Save it in a file with a .scad extension (e.g., json_simulation.scad).
Open the file in OpenSCAD.
Look at the console output to see the echoed values.

Note that OpenSCAD is primarily a 3D modeling language and lacks many features of general-purpose programming languages. This example is a very simplified representation of JSON-like concepts and doesn’t include features like encoding/decoding or working with complex nested structures.
