I try to write the plugin now:
…
from zope.interface import implements
from twisted.application.service import IServiceMaker
from twisted.application import internet
from twisted.plugin import IPlugin
from twisted.python import usage
from meteo import meteoFactory
class Options(usage.Options):
optParameters = [ ['port', 'p', 80, 'The port number to listen
on.'],
['ipv4_address', '4', None,
'The IPv4 address to listen on.'],
['ipv6_address', '6', None,
'The IPv6 address to listen on.']]
class MeteoServiceMaker(object):
implements(IServiceMaker, IPlugin)
tapname = 'meteo'
description = 'A web application for the meteo package'
options = Options
def makeService(self, options):
"""
Constructs a TCP server from a factory defined in meteo.py
"""
return internet.TCPServer( int(options['port'],
interface=options['ipv4_address'], ## how do it set the ip6 address?
meteoFactory())
serviceMaker = MeteoServiceMaker()
---
--- relevant part of metro.py:
resource = RootWeatherPage()
meteoFactory = Site(resource)
---
Currently, this gives following error:
---

What is wrong there?
