greenlet Description

Lightweight in-process concurrent programming greenlet is a spin-off of Stackless, a version of CPython that supports micro-threads called "tasklets". Tasklets run pseudo-concurrently (typically in a single or a few OS-level threads) and are synchronized with data exchanges on "channels".A "greenlet", on the other hand, is a still more primitive notion of micro- thread with no implicit scheduling; coroutines, in other words. This is useful when you want to control exactly when your code runs. You can build custom scheduled micro-threads on top of greenlet; however, it seems that greenlets are useful on their own as a way to make advanced control flow structures. For example, we can recreate generators; the difference with Python's own generators is that our generators can call nested functions and the nested functions can yield values too. Additionally, you don't need a "yield" keyword. See the example in tests/test_generator.py.Greenlets are provided as a C extension module for the regular unmodified interpreter.Greenlets are lightweight coroutines in-process concurrent programming. This package is the py.magic.greenlet module from the py lib.Who is using Greenlet?There are several libraries that use Greenlet as a more flexible alternative to Python's built in coroutine support: * Concurrence * Eventlet * GeventGetting GreenletThe easiest way to get Greenlet is to install it with pip or easy_install:pip install greenleteasy_install greenlet Requirements: · Python
