<hawkowl> we have always been at war with 16.7
For information on what's new in Twisted 17.1.0, see the
NEWS <NEWS>_ file that comes with the distribution.
What is this?
Twisted is an event-based framework for internet applications, supporting Python 2.7 and Python 3.3+. It includes modules for many different purposes, including the following:
twisted.web: HTTP clients and servers, HTML templating, and a WSGI server
twisted.conch: SSHv2 and Telnet clients and servers and terminal emulators
twisted.words: Clients and servers for IRC, XMPP, and other IM protocols
twisted.mail: IMAPv4, POP3, SMTP clients and servers
twisted.positioning: Tools for communicating with NMEA-compatible GPS receivers
twisted.names: DNS client and tools for making your own DNS servers
twisted.trial: A unit testing framework that integrates well with Twisted-based code.
Twisted supports all major system event loops --
select (all platforms),
poll (most POSIX platforms),
kqueue (FreeBSD, OS X), IOCP (Windows), and various GUI event loops (GTK+2/3, QT, wxWidgets).
Third-party reactors can plug into Twisted, and provide support for additional event loops.
To install the latest version of Twisted using pip::
$ pip install twisted
Additional instructions for installing this software are in
the installation instructions <INSTALL.rst>_.
Documentation and Support
Twisted's documentation is available from the
Twisted Matrix website <http://twistedmatrix.com/documents/current/>_.
This documentation contains how-tos, code examples, and an API reference.
Help is also available on the
Twisted mailing list <http://twistedmatrix.com/cgi-bin/mailman/listinfo/twisted-python>_.
There is also a pair of very lively IRC channels,
#twisted (for general Twisted questions) and
#twisted.web (for Twisted Web), on
Twisted has a comprehensive test suite, which can be run by
$ tox -l # to view all test environments $ tox -e py27-tests # to run the tests for Python 2.7 $ tox -e py34-tests # to run the tests for Python 3.4
You can test running the test suite under the different reactors with the
TWISTED_REACTOR environment variable::
$ env TWISTED_REACTOR=epoll tox -e py27-tests
Some of these tests may fail if you:
- don't have the dependencies required for a particular subsystem installed,
- have a firewall blocking some ports (or things like Multicast, which Linux NAT has shown itself to do), or
- run them as root.
