Compiler errors Visual Studio.

[nicokruithof]

#include <vu8/Module.hpp>

void test() {}

void register()
{
    vu8::Module module;
    module("print", &print)
        .Set<void(), &test>("test");
}

gives the following errors with Visual Studio 2010 x64:

1> error C2975: 'Ptr' : invalid template argument for 'vu8::Module::Set', expected compile-time constant expression
1> vu8\src\vu8/Module.hpp(74) : see declaration of 'Ptr'
1> error C2977: 'vu8::Module::Set' : too many template arguments
1> vu8\src\vu8/Module.hpp(69) : see declaration of 'vu8::Module::Set'
1> error C2780: 'vu8::Module &vu8::Module::Set(const char *,vu8::Class<T,F> &)' : expects 2 arguments - 1 provided
1> vu8\src\vu8/Module.hpp(64) : see declaration of 'vu8::Module::Set'

It seems Visual Studio is still not fully conforming to the C++ spec. Pointer to member functions are stated to be allowed as compile-time constant template parameters and yet here Visual Studio is still disallowing it with a bogus error message. Shame.

I believe that boost::multi_index_container has a hack for this in VS inside its "boost::member" class.

I'll have to look into it.

Ah Microsoft.. when they aren't making you rewrite your HTML and CSS due to their inadequacies they're making you rewrite your C++.

[nicokruithof]

Yes, I guess so. I normally use boost::bind with member functions. I can
test, but it'll probably take me much more time to dive into that it'll
take you.

This isn't a case for boost::bind as I need to be able to represent the method pointer at compile time and boost::bind is a purely runtime abstraction.

At any rate I cannot fix this in Visual Studio as I cannot afford to purchase Microsoft Windows or Visual Studio.

[nicokruithof]

ok. I'll dive into boost::multi_index_container and see whether I can resolve the error.

By the way, Visual Studio has a free version (and a three month trial for the professional edition). But I'd rather work on linux as well.

It'll be a hard one I'm pushing the C++ compiler about as hard as it can go for this project.

I'd like to support Windows with all my code but I don't wish to break the law or spend that much money on a shoddy operating system.

[insidewhy]

Well breaking the law is okay but not over a stupid OS :)

Another option for me would be to use cvv8 to generate the InvocationCallback function and then add that to the vu8::Module. I like the vu8 interface better as it is cleaner, but already had the functions generated by cvv8.

[insidewhy]

Yeah I helped the author of cvv8 out with his template work.

Now maybe he can help me get it working in VS :)

[nicokruithof]

Hi,

I got things working on windows by combining vu8 and cvv8:

v8::Handlev8::Value print(const v8::Arguments& args);
void sleep(double s);

vu8::Module module;
module("print", &print);
module.Set("sleep", cvv8::FunctionToInCa<void (double), ::sleep,
true>::Call);

Not very nice, but not too much boilerplate either.

Now I'd like to wrap some of my C++ classes with in a javascript class to
provide a way to interact with them from the javascript engine. So the
classes already exist in my application and I'd only like to create a
javascript interface to them. Do you know an example that I could use as a
starting point?

Best regards,
Nico

Damn Visual Studio. Also I'm working on this in my fork, not my work account fork.

[nicokruithof]

TSA is your work account? What kind of work do you do? Where do you live?

I live in the UK, TSA is my work account. I code and design software there mainly in C++.

[nicokruithof]

Is there anything I could do? Implement / test on visual studio?

Happy to accept patches for anything, thank you so much for your help.

The only reason I haven't accepted your other patches yet is because I wanted to discuss a few things about that with you, I'll leave a comment in that bug.
