README

        
The greenlet package 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 for in-process concurrent

programming.

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`_

 - `Gevent`_

.. _Concurrence: http://opensource.hyves.org/concurrence/

.. _Eventlet: http://eventlet.net/

.. _Gevent: http://www.gevent.org/

Getting Greenlet

================

The easiest way to get Greenlet is to install it with pip or

easy_install::

  pip install greenlet

  easy_install greenlet

Source code archives and windows installers are available on the

python package index at http://pypi.python.org/pypi/greenlet

The source code repository is hosted on github:

https://github.com/python-greenlet/greenlet

The master branch - i.e. the `development version`_ - can be installed

directly by running one of the following::

  pip install greenlet==dev

  easy_install greenlet==dev
