Pythia and Seastar C++14

This example is input into the transpiler, the extra python-like syntax is optimized for c++14 and Seastar. Seastar is optimized for OSv for the best IO performance possible.

with stack:
 def handle_connection(s:connected_socket, a:socket_address) -> future<>:
  output = s.output()
  input = s.input()

  return do_with( s, output, input ):
   return repeat() and then( callback=lambda:output.close() ):
    return input.read() and then( capture=[output], future=[buf] ):
     if buf:
      return output.write( move(buf) ) and then():
       return next
     else:
      return stop

output

the transpiled c++14 output.

future<> handle_connection(connected_socket s, socket_address a) {

 auto output = s.output();
 auto input = s.input();
 return do_with(std::move(s),std::move(output),std::move(input), [] (auto& s,auto& output,auto& input) {
  return repeat([&] {
   return input.read().then([&output] (auto buf){
    if (buf==true) {
     return output.write(std::move(buf)).then([] (){
      return stop_iteration::no;
     });
    } else {
     return make_ready_future(stop_iteration::yes);
    }
   });
  }).then([&](){ return output.close(); });
