Greenlets are lightweight coroutines for in-process concurrent
|
||
|
|
programming.
|
||
|
|
|
||
|
|
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 `test_generator.py
|
||
|
|
<https://github.com/python-greenlet/greenlet/blob/adca19bf1f287b3395896a8f41f3f4fd1797fdc7/src/greenlet/tests/test_generator.py#L1>`_).
|
||
|
|
|
||
|
|
Greenlets are provided as a C extension module for the regular unmodified
|
||
|
|
interpreter.

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::
|
||
|
|
|
||
|
|
pip install greenlet
|
||
|
|
|
||
|
|
|
||
|
|
Source code archives and binary distributions are available on the
|
||
|
|
python package index at https://pypi.org/project/greenlet
|
||
|
|
|
||
|
|
The source code repository is hosted on github:
