jbandela / stackless_coroutine Goto Github PK

Hello,

Congratulations for your stackless implementation, is very nice and interesting for me. I have a problem when compile in gcc 4.9 (works in clang 3.6):

/home/travis/build/makiolo/asyncply/stackless_coroutine/stackless_coroutine.hpp:223:16: error: template declaration of ‘constexpr const bool stackless_coroutine::detail::has_finished_storage_v’ (Travis source)

Thanks. Ricardo.

Not sure if this library is still being worked on but I wanted to use some function objects that stored some state that mutated as the co-routine looped. However operator() has to be const or else I get the error
error C3848: expression having type 'const signal_cv' would lose some const-volatile qualifiers in order to call 'auto signal_cv::operator ()<DC,Value>(Context &,Vars &)

The code reads:

template<typename Context, typename Vars>
auto operator()(Context &c, Vars &v)
{
cv.notify_all();
return c.do_next();
}

I can get around it with mutable members but I was just wondering if I've missed something, it's as designed or a VS issue?

Thanks

I'm writing a function object that needs to check a state variable when it starts and if a condition is met simply continue on the pipeline. If the condition is false I need to issue an async operation (ASIO). Because I'm using async I need to return context.do_async(), however this means the return value in an auto operator() is different than earlier where it was context.do_next().

Is there a way to handle these cases elegantly?

Thanks

I'm wondering if it's possible to port the library to C++11.
