python-zeroconf

This is fork of pyzeroconf, Multicast DNS Service Discovery for Python, originally by Paul Scott-Murphy (https://github.com/paulsm/pyzeroconf), modified by William McBrine (https://github.com/wmcbrine/pyzeroconf).

This fork is used in all of my TiVo-related projects: HME for Python (and therefore HME/VLC), Network Remote, Remote Proxy, and pyTivo. Before this, I was tracking the changes for zeroconf.py in three separate repos. I figured I should have an authoritative source.

Although I make changes based on my experience with TiVos, I expect that they're generally applicable. This version also includes patches found on the now-defunct (?) Launchpad repo of pyzeroconf, and elsewhere around the net -- not always well-documented, sorry.

Compatible with:

• Bonjour
• Avahi

Compared to some other Zeroconf/Bonjour/Avahi Python packages, python-zeroconf:

• isn't tied to Bonjour or Avahi
• doesn't use D-Bus
• doesn't force you to use particular event loop or Twisted
• is pip-installable
• has PyPI distribution

Python compatibility

• CPython 2.6, 2.7, 3.3+
• PyPy 2.2+ (possibly 1.9-2.1 as well)

How to get python-zeroconf?

• PyPI page https://pypi.python.org/pypi/zeroconf
• GitHub project https://github.com/jstasiak/python-zeroconf

The easiest way to install python-zeroconf is using pip:

pip install zeroconf

How do I use it?

Here's an example:

from six.moves import input
from zeroconf import ServiceBrowser, Zeroconf


class MyListener(object):

    def remove_service(self, zeroconf, type, name):
        print("Service %s removed" % (name,))

    def add_service(self, zeroconf, type, name):
        info = zeroconf.get_service_info(type, name)
        print("Service %s added, service info: %s" % (name, info))


zeroconf = Zeroconf()
listener = MyListener()
browser = ServiceBrowser(zeroconf, "_http._tcp.local.", listener)
try:
    input("Press enter to exit...\n\n")
finally:
    zeroconf.close()

See examples directory for more.
