jtypes.jep 3.8.2a2

Java Embedded Python (ctypes/cffi-based Jep)

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.

PyPI record.

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

Requirements

• Java >= 1.7 - either the Sun/Oracle JRE/JDK or OpenJDK.

• NumPy >= 1.7 (optional)
