libpy is a library to help you write amazing Python extensions in C++.
libpy makes it easy to expose C++ code to Python.
libpy lets you automatically wrap functions and classes.
libpy is designed for high performance and safety: libpy extension modules should be both faster and safer than using the C API directly.
libpy supports:
- macOS/Linux
- Python >=3.5
libpy requires:
- gcc>=9 or clang>=10
- numpy>=1.11.3
libpy optionally provides wrappers for the following libraries:
- google sparsehash
To install for development:
$ make
Otherwise, pip install libpy, making sure CC and CXX environment variables are set to the the right compiler.
Note: The installation of libpy will use the python executable to
figure out information about your environment. If you are not using a virtual
environment or python does not point to the Python installation you want
to use (checked with which python and python --version) you must
point to your Python executable using the PYTHON environment variable,
i.e. PYTHON=python3 make or PYTHON=python3 pip3 install libpy.
To run the unit tests, invoke:
$ make test
