Prophy is a statically typed, binary, tag-free, unpacked serialization protocol.
You can define message schema:
struct MyMsg
{
u16 x<>;
};
generate codecs for chosen languages:
prophyc --python_out . --cpp_full_out . --cpp_out . test.prophy
and serialize data in Python:
>>> import test
>>> msg = test.MyMsg()
>>> msg.x[:] = [1, 2, 3]
>>> msg.encode('<')
'\x03\x00\x00\x00\x01\x00\x02\x00\x03\x00\x00\x00'
>>> print msg
x: 1
x: 2
x: 3
in C++:
#include <iostream>
#include <iterator>
#include "test.ppf.hpp"
int main()
{
prophy::generated::MyMsg msg{{1, 2, 3}};
std::vector<uint8_t> data = msg.encode();
std::copy(data.begin(), data.end(), std::ostream_iterator<unsigned>(std::cout, " "));
std::cout << '\n' << msg.print();
return 0;
}
3 0 0 0 1 0 2 0 3 0 0 0 x: 1 x: 2 x: 3
again in C++ (half hand-rolled, compiler-dependent, but fastest option):
#include <iostream>
#include <iterator>
#include <cstdlib>
#include "test.pp.hpp"
int main()
{
MyMsg* msg = static_cast<MyMsg*>(std::malloc(12));
msg->num_of_x = 3;
msg->x[0] = 1;
msg->x[1] = 2;
msg->x[2] = 3;
std::copy((uint8_t*)msg, ((uint8_t*)msg) + 12, std::ostream_iterator<unsigned>(std::cout, " "));
std::cout << '\n';
return 0;
}
3 0 0 0 1 0 2 0 3 0 0 0
