Java Embedded Python (ctypes/cffi-based Jep)
Project description
Currently only as placeholder (because a base package jtypes.jvm is still in development)
jtypes.jep
Java Embedded Python.
Overview
jtypes.jep embeds CPython in Java.jtypes.jep is a lightweight Python package, based on the ctypes or cffi library.It is an almost fully compliant implementation of Mike Johnson’s Jep package by reimplementing its functionality in a clean Python instead of C.
About Jep:
Borrowed from the original website:
Jep embeds CPython in Java through JNI and is safe to use in a heavily threaded environment.
Some benefits of embedding CPython in a JVM:
Using the native Python interpreter may be much faster than alternatives.
Python is mature, well supported, and well documented.
Access to high quality Python modules, both native CPython extensions and Python-based.
Compilers and assorted Python tools are as mature as the language.
Python is an interpreted language, enabling scripting of established Java code without requiring recompilation.
Both Java and Python are cross platform, enabling deployment to different operating systems.
Notable features
Interactive Jep console much like Python’s interactive console
Supports multiple, simultaneous, mostly sandboxed sub-interpreters
Numpy support for Java primitive arrays
