I think you can use ffi.from_buffer and ffi.cast from cffi. On Fri, Sep 2, 2016 at 8:53 AM Carl Kleffner wrote: > fork / extension of cffiwrap: > > > *"cfficloak - A simple but flexible module for creating object-oriented, > pythonic CFFI wrappers.This is an extension of > https://bitbucket.or

Hey Ian - I hope I gave Cython a fair comment, but I have to add the disclaimer that your capability to understand/implement those solutions/workarounds in that project is greatly enhanced from your knowing the innards of Cython from being core developer on the Cython project. This doesn't detract

Re: [Numpy-discussion] State-of-the-art to use a C/C++ library from Python

We use Cython very heavily in DyND's Python bindings. It has worked well for us even when working with some very modern C++. That said, a lot depends on exactly which C++ features you want to expose as a part of the interface. Interfaces that require things like non-type template parameters or vari

Re: [Numpy-discussion] State-of-the-art to use a C/C++ library from Python

I just wanted to follow up on the C++ side of OP email - Cython has quite a few difficulties working with C++ code at the moment. It's really more of a C solution most of the time and you must split things up into a mostly C call interface (that is the C code Cython can call) and limit exposure/co

Hi all There are several ways on how to use C/C++ code from Python with NumPy, as given in http://docs.scipy.org/doc/numpy/user/c-info.html . Furthermore, there's at least pybind11. I'm not quite sure which approach is state-of-the-art as of 2016. How would you do it if you had to make a C/C++ li
