JyNI was accepted for GSoC once again! 2017 GSoC project page 2015 GSoC project blog Huge thanks to everyone who made this possible! Most notably to Jim Baker for mentoring the entire proposal and the project itself. Further thanks go to Frank Wierzbicki and Darjus Loktevic for mentoring this brand new 2017 JyNI GSoC project. Jython: Develop Windows version of JyNI and ideally support all extensions currently workable on POSIX (e.g. ctypes, NumPy) Abstract JyNI is a compatibility layer with the goal to enable Jython to use native CPython extensions like NumPy or SciPy. So far it was developed on Linux and some additional effort was spent to let the core part work properly on OSX. In principle the current version of JyNI is workable on POSIX platforms. I propose to create a proper Windows version of JyNI. A fully accurate implementation of this proposal includes to establish workability of all extensions and features that are currently supported on POSIX platforms.
