- Description: 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 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`_
- - `Gevent`_

-
- Getting Greenlet
- ================
-
- The easiest way to get Greenlet is to install it with pip or easy_install::
-
- pip install greenlet
- easy_install greenlet
-
- The development `tip`_ is available via these tools as well::
-
- pip install greenlet==dev
- easy_install greenlet==dev
-
