Redirects text send to sys.stdout/stderr from Python to a user defined C/C++ function.

When you write your own interpreter for embedded python, you are maybe interested inthe output given by the Python interpreter.This header-only project provvides the functionality to passthe output to any given function.

• redirect stdout/stderr to a plain function, lambda or Functor
• supports GUI programs without default console
• doesn't add any function to pythons global namespace
• doesn't add any additional python module

• pybind11
• ORBoost.Python

If you use Boost, define TYTI_PYLOGHOOK_USE_BOOST before include PyLogHook.h.

It is header only. Just addPyLogHook.h to your project which should already link against boost.python or pybind11.

Call one of the functions in namespacetyti::pylog.

// in case of using Boost.Python#defineTYTI_PYLOGHOOK_USE_BOOST//------------------------------#include<PyLogHook.h>voidmy_stdout(constchar* w){    std::cout << w;}voidmy_stderr(constchar* w){    std::cerr << w;}...//somewhere e.g. in your main function, after Py_Initialize()tyti::pylog::redirect_stdout(my_stdout);tyti::pylog::redirect_stderr(my_stderr);

Before calling one of the functions, make sure

• python is initalized (Py_Initialize())
• you hold the GIL, if multithreading is activated

If anything went wrong, a Python exception was raised.You can check, if a there is a pending exception viaPyErr_Occurred() (Seetests).
