implementing a module to replace sys.stdout

[tomluchowski]

Hello,
I wanted to have a python console in my game Opendungeons-plus. I use the boilerplate code like this to force the printing python's output:

// implement a module to replace sys.stdout

#include <iostream>
#include <pybind11/embed.h>

PYBIND11_EMBEDDED_MODULE(my_sys, m) {
    struct my_stdout {
        my_stdout() = default;
        my_stdout(const my_stdout &) = default;
        my_stdout(my_stdout &&) = default;
    };

    py::class_<my_stdout> my_stdout(m, "my_stdout");
    my_stdout.def_static("write", [](py::object buffer) {
        std::cout << buffer.cast<std::string>();
    });
    my_stdout.def_static("flush", []() {
        std::cout << std::flush;
    });

    m.def("hook_stdout", []() {
        auto py_sys = py::module::import("sys");
        auto my_sys = py::module::import("my_sys");
        py_sys.attr("stdout") = my_sys.attr("my_stdout");
    });
}

I know that py:list is py:object , however the expression [1,2,3] nor print([1,2,3]) does not show what it should do ..... How shall I modify this code so every expression and every print show on the screen ? ( CEGUI's widget)
