So, I did eventually get this to work very much like SpiderMonkey's
evalcx function. Here's the code if anyone else is interested:
usage:
evalcx( code_to_execute, global_object (default: this), keep_changes
(bool, should changed global be written back to the object?) )
returns the result of the executed code.
static v8::Handle<v8::Value> EvalCX (const v8::Arguments& args)
{
HandleScope handle_scope;
Handle<Context> context = Context::New();
context->SetSecurityToken(
Context::GetCurrent()->GetSecurityToken()
);
Context::Scope context_scope(context);
Handle<String> code = args[0]->ToString();
Handle<Object> sandbox = args.Length() >= 1 ? args[1]->ToObject() :
Context::GetCurrent()->Global();
// share global datas
copy_obj( sandbox, context->Global());
context->Enter();
Handle<Script> script = Script::Compile(code, String::New("evalcx"));
Handle<Value> result;
if (script.IsEmpty()) {
result = ThrowException(String::New("Error parsing script"));
} else {
result = script->Run();
if (result.IsEmpty()) {
result = v8::ThrowException(v8::String::New("Error
running
script"));
}
}
if (args.Length() >= 3 && args[2]->IsTrue()) {
copy_obj( context->Global(), sandbox );
}
context->DetachGlobal();
context->Exit();
return result;
}
