* Package name : python-greenlet Version : 0.3.1 Upstream Author : Kyle Ambroff <k...@ambroff.com> * URL : http://bitbucket.org/ambroff/greenlet * License : MIT Programming Lang: Python Description : Lightweight 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 tests/test_generator.py. . Greenlets are provided as a C extension module for the regular unmodified interpreter. -- Monty Taylor -- To UNSUBSCRIBE, email to debian-wnpp-requ...@lists.debian.org with a subject of "unsubscribe".
