[v8-users] Script handle and return value

[Remi Gillig]

Hello,

I have a little problem with this code :

#include <exception>
#include <string>
#include <v8/v8.h>

using namespace v8;

class Engine
{
private:
    Persistent<Context> context;
public:
    Engine()
    {
        context = Context::New();
    }

    Handle<Value> Run(const std::string& scriptContent)
    {
        Context::Scope contextScope(context);

        HandleScope handleScope;

        Handle<String> source = String::New(scriptContent.c_str());

        Handle<Script> script = Script::Compile(source);

        TryCatch trycatch;

        Handle<Value> result = script->Run();

        if (result.IsEmpty())
        {
            Handle<Value> exception = trycatch.Exception();
            String::AsciiValue exceptionString(exception);
            throw std::exception(*exceptionString);
        }

        return handleScope.Close(result);
    }

    ~Engine()
    {
        context.Dispose();
    }
};

int main(int argc, char* argv[])
{
    Engine engine;

    HandleScope handleScope;
    Handle<Value> str = engine.Run("42;");

    String::AsciiValue ascii(str);
    printf("%s", *ascii);

    return 0;
}

I am using Visual Studio 2008 and this code crashes at the conversion
to AsciiValue and the debugger breaks at line 38 in contexts.cc inside
Context::builtins() : GlobalObject* object = global();

What I would like to create is a little class which would load
configuration scripts and keep the context so that I can retrieve the
config data for my application.

Thanks for any help!

Remi Gillig.
