With JyNI alpha 5, I proudly announce the first version of JyNI that also runs on Windows. JyNI is a layer that allows Jython to load native CPython extensions. Most notably ctypes and NumPy are already workable (core functionality). Take a look at jyni.org or go directly to the release: https://github.com/Stewori/JyNI/releases/tag/v2.7-alpha.5 Binaries are provided for Linux, OS X and Windows. It should in principle also work on other POSIX platforms. NumPy support -------------

From JyNI alpha 4 onwards, some NumPy support is available. For JyNI alpha 5 featuring Windows support, we explicitly asserted that NumPy works on Windows equally well as on Linux and OS X, i.e. up to known limitations.

For details about NumPy support see https://github.com/Stewori/JyNI/releases/tag/v2.7-alpha.4 https://github.com/Stewori/JyNI/issues/2 Google Summer of Code --------------------- JyNI alpha 5 was mainly developed within a Google Summer of Code project: https://summerofcode.withgoogle.com/projects/#4931062149939200 http://gsoc2017-jyni.blogspot.de for details. What comes next? ---------------- The Python C API is not yet fully supported. A major goal for the next release is to add support for the buffer protocol, which is currently blocking support for SciPy and various other extensions. Enjoy! -Stefan
