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`_

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 https://pypi.python.org/pypi/greenlet
|
||
|
|
|
||
|
|
The source code repository is hosted on github:
