  9. 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".
  10. 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.
  11. Greenlets are provided as a C extension module for the regular unmodified interpreter.
  12. Greenlets are lightweight coroutines in-process concurrent programming. This package is the py.magic.greenlet module from the `py lib`_.

  14. Who is using Greenlet?
  15. ======================
  16. There are several libraries that use Greenlet as a more flexible alternative to Python's built in coroutine support:
  17. - `Concurrence`_
  18. - `Eventlet`_
  19. - `Gevent`_
  20. .. _Concurrence: http://opensource.hyves.org/concurrence/
  21. .. _Eventlet: http://eventlet.net/
  22. .. _Gevent: http://www.gevent.org/
  23. Getting Greenlet
  24. ================
  25. The easiest way to get Greenlet is to install it with pip or easy_install::
  26. pip install greenlet
  27. easy_install greenlet
  28. The development `tip`_ is available via these tools as well::
  29. pip install greenlet==dev
  30. easy_install greenlet==dev
