Pure Python Multicast DNS Service Discovery Library (Bonjour/Avahi compatible)

Project description

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:

  • has zero external dependencies
  • 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?

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

pip install zeroconf

How do I use it?

Here’s an example:

from zeroconf import raw_input, ServiceBrowser, Zeroconf


class MyListener(object):

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

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


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

See examples directory for more.
