The cpp_fort_and_py example demonstrates how to pass Conduit Nodes between C++, Fortran, and Python. It is a standalone example that you can build with CMake against your Conduit install.
You can find this example under src/examples/cpp_fort_and_py in Conduit's source tree, or under examples/conduit/cpp_fort_and_py in a Conduit install.
It includes source for an embedded python interpreter and also shows how to create a Fortran module that binds Conduit Nodes via Conduit's C-API.
It creates two executables:
conduit_cpp_and_py_ex
Demo of C++ to Python and vice versa
conduit_fort_and_py_ex
Demo of Fortran to Python and vice versa
This demos wrapping Conduit Nodes, effectively creating referenced data across languages. You can also use set_external to directly access and change zero-copied data.
Please see the main CMakeList.txt file for details on building and running:
