I'm trying to convert Persistent<Context> to a void* to be passed to C,
then back. I understand that there are a lot of changes happening to
Persistent.
This is what I have so far, which is probably wrong:
void* isolate_new() {
Isolate *isolate = Isolate::New();
return (void*)(isolate);
}
void* context_new(void* iso) {
Isolate *isolate = (Isolate*)(iso);
isolate->Enter();
HandleScope handle_scope(isolate);
Handle<Context> context = Context::New(isolate);
Persistent<Context> pcontext(isolate, context);
isolate->Exit();
return (void*)(&Persistent<Context>::Cast(pcontext));
}
void test(void *iso, void *ctx) {
Isolate *isolate = (Isolate*)(iso);
isolate->Enter();
Handle<Context> context = *(Handle<Context>*)(ctx); // Needs to be
Persistent<Context>, but can't figure out how to get it back.
HandleScope handle_scope(isolate);
Context::Scope context_scope(context); // This needs to be
context_scope(isolate, context) w/ Persistent
Local<String> source = String::New("'Hello' + ', World!'");
Local<Script> script = Script::Compile(source);
Local<Value> result = script->Run();
String::AsciiValue ascii(result);
isolate->Exit();
printf("%s\n", *ascii);
}
I'm having difficulty getting things to compile. This is the closest I was
able to get, but it crashes. How do I do this correctly? Should I pretty
much give up on this until all the changes are made?
