Hi!

I'm pretty new to spidermonkey and I'm amazed fast I could integrate
it into my app. I guess I'm just blind, but I can't find a function to
create an instance of a Class within the context.

-- Code --
JSClass dummyClass =  {
    "Dummy", JSCLASS_HAS_PRIVATE,
    JS_PropertyStub, JS_PropertyStub,
    dummyGetFunc, dummySetFunc,
    JS_EnumerateStub, JS_ResolveStub, 
    JS_ConvertStub, dummyDestructor
};
-- /Code --

Assume all these functions exists, and that the class was registered
via JS_InitClass().

Now I want to populate my context with some instances of Dummy
objects. Right now what I do is something like this:

-- Code --
jsval rval;
char* script = "test = new Dummy();";
JS_EvaluateScript(
    jsContext, jsGlobalObj, 
    script, strlen(script), 
    "[init]", __LINE__, 
    &rval); 
-- /Code --

To ensure that a variable named "test" of type "Dummy" exists in the
context.
Is there a pure C way of doing this? Calling JS_EvaluateScript() seems
hackish...


Thanks,
