Question

I’m a complete python n00b here and just trying to mash a few bits together to make a project work but i’m struggling with some of the syntax i think.

Here is my script i have so far:

#!/usr/bin/env python

from plugin import *
from siriObjects.systemObjects import ResultCallback
import uuid
import json
import random
import types
import urllib
import urllib2
import random
import re
import select
import socket
import struct
import sys
import thread
import time

class tivoRemote(Plugin):

        tivo_address = '192.168.0.9'
        tivo_name = ''
        tivo_swversions = {}
        have_zc = True
        captions_on = False
        sock = None
        outer = None


        def connect():
            """ Connect to the TiVo within five seconds or report error. """
            global sock
            try:
                sock = socket.socket()
                sock.settimeout(5)
                sock.connect((tivo_address, 31339))
                sock.settimeout(None)
            except Exception, msg:
                msg = 'Could not connect to %s:\n%s' % (tivo_name, msg)
                print(msg)

        def send(message):
            """ The core output function, called from irsend(). Re-connect if
                necessary (including restarting the status_update thread), send
                message, sleep, and check for errors.
                """

            if not sock:
                self.connect()
                thread.start_new_thread(status_update, ())
            try:
                sock.sendall(message)
                time.sleep(0.1)
            except Exception, msg:
                error_window(str(msg))


        def irsend(*codes):
            """ Expand a command sequence for send(). """
            for each in codes:
                self.send('IRCODE %s\r' % each)


        @register("en-US", ".*Change.*Channel.*")
        def channelChanger(self, speech, language, matchedRegex):
                if language == 'en-US':
                        answer = self.ask(u"Which channel would you like?")
                        self.say(u"Ok, one moment..".format(answer))
                        self.connect()
                        self.irsend(answer)
                self.complete_request()

and the error i’m getting is:

Traceback (most recent call last):
  File "/home/pi/SiriServerCore/plugin.py", line 150, in run
    self.__method(self, self.__speech, self.__lang,        self.__method.__dict__[__criteria_key__][self.__lang].match(self.__speech))
  File "/home/pi/SiriServerCore/plugins/tivoRemote/__init__.py", line 70, in     channelChanger
    self.irsend(format(answer))
  File "/home/pi/SiriServerCore/plugins/tivoRemote/__init__.py", line 61, in irsend
    self.send('IRCODE %s\r' % each)
NameError: global name 'self' is not defined

If i remove the ‘self.’ i get the same error but saying ‘send’ is not defined.

Thanks in advance for any help 🙂

More likely to work:

class tivoRemote(Plugin):

    def __init__(self):
        self.tivo_address = '192.168.0.9'
        self.tivo_name = ''
        self.tivo_swversions = {}
        self.have_zc = True
        self.captions_on = False
        self.sock = None
        self.outer = None


    def connect(self):
        """ Connect to the TiVo within five seconds or report error. """
        try:
            sock = socket.socket()
            sock.settimeout(5)
            sock.connect((tivo_address, 31339))
            sock.settimeout(None)
        except Exception, msg:
            msg = 'Could not connect to %s:\n%s' % (tivo_name, msg)
            print(msg)
        self.sock = sock

    def send(self, message):
        """ The core output function, called from irsend(). Re-connect if
            necessary (including restarting the status_update thread), send
            message, sleep, and check for errors.
        """

        if not self.sock:
            self.connect()
            thread.start_new_thread(status_update, ()) # status_update must be some global at this point
        try:
            self.sock.sendall(message)
            time.sleep(0.1)
        except Exception, msg:
            error_window(str(msg))


    def irsend(self, *codes):
        """ Expand a command sequence for send(). """
        for each in codes:
            self.send('IRCODE %s\r' % each)


    @register("en-US", ".*Change.*Channel.*")
    def channelChanger(self, speech, language, matchedRegex):
            if language == 'en-US':
                    answer = self.ask(u"Which channel would you like?")
                    self.say(u"Ok, one moment..".format(answer))
                    self.connect()
                    self.irsend(answer)
            self.complete_request()

You need to use self when defining methods and you have to use it to access the current instance.
