The sandbox module allows the creation of isolated JSCore contexts with individual global objects. It is useful as a literal "sandbox" or in a variety of other contexts.
sandbox = imports.sandbox;
<xi:include></xi:include>
Below are several examples of using the Seed Sandbox module. For additional resources, consult the examples/ folder of the Seed source
Example 17.
sandbox = imports.sandbox;
ctx = new sandbox.Context();
ctx.eval("b = 2+2");
print(ctx.global.b); //4
ctx.global.b = new Gtk.Window(); // Possible to expose objects to the context.
ctx.eval("b.show()");
