For information on changes in this release, see the `NEWS <https://github.com/twisted/twisted/blob/trunk/NEWS.rst>`_ file.
What is this?
-------------
Twisted is an event-based framework for internet applications, supporting Python 3.6+.
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), ``epoll`` (Linux), ``kqueue`` (FreeBSD, macOS), 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.
Installing
----------
To install the latest version of Twisted using pip::
$ pip install twisted
Additional instructions for installing this software are in `the installation instructions <https://github.com/twisted/twisted/blob/trunk/INSTALL.rst>`_.
Documentation and Support
-------------------------
Twisted's documentation is available from the `Twisted Matrix website <https://twistedmatrix.com/documents/current/>`_.
This documentation contains how-tos, code examples, and an API reference.
Help is also available on the `Twisted mailing list <https://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 `irc.libera.chat <https://web.libera.chat/>_`.
Unit Tests
----------
Twisted has a comprehensive test suite, which can be run by ``tox``::
$ tox -l # to view all test environments
$ tox -e nocov # to run all the tests without coverage
$ tox -e withcov # to run all the tests with coverage
$ tox -e alldeps-withcov-posix # install all dependencies, run tests with coverage on POSIX platform
You can test running the test suite under the different reactors with the ``TWISTED_REACTOR`` environment variable::
$ env TWISTED_REACTOR=epoll tox -e alldeps-withcov-posix
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.
Static Code Checkers
--------------------
You can ensure that code complies to Twisted `coding standards <https://twistedmatrix.com/documents/current/core/development/policy/coding-standard.html>`_::
$ tox -e lint # run pre-commit to check coding stanards
$ tox -e mypy # run MyPy static type checker to check for type errors
Or, for speed, use pre-commit directly::
$ pipx run pre-commit run
