A plugin's basic structure

import ..... # what ever needed

#you will need to import these
from modules.channel import Channel
from exception import *

__cname__ = "wordpress"      #or whichever channel

class Wordpress(Channel):
    def __init__(self):
        self.__fields__ = ["Message","Title"]   # and whatever the plugin requires for sending a message

    def VerifyCredentials(self):
        # this method should check if the auth info available in the .publish file valid
        # and return True if it checks out and false if it fails

    def GetKeys(self):
        # You can look at this function from any other plugin, u'll just need to make a few changes
        # which are channel specific

    def Authorize(self):
        # here ask user for authentication info and save it in the .publish file
        # how to do that can be seen if u look at any existing plugins
        # Finally after saving the auth info
        # call VerifyCredentials and check if the given info is worth it
        # if it fails do :
        # raise AuthorizationError({'Wordpress':'Authorization Failed'})
        # i.e raise the AuthorizationError exception and pass a dict with channel name as key
        # and value as the message to be returned to ui

    def VerifyFields(self, fields):
        # fields parameter passed is a dictionary of the format :
        # {field1:value, field2:value, ...}
        # here the plugin required fields are checked if they are valid
        # returns True/False
        # for eg: checks if the message passed is empty or not

    def SendMsg(self, Message):
        # Message: this is a dictionary in the format
        # {field1:value, field2:value, ...}
        # and here do what is necessary to send message to this channel
        # finally return message like
        # return {'Wordpress':'Blog posted'}
        # return {'Wordpress':'Blog posting failed'}
        # return {'Wordpress':'Unable to access network/server'}
        # u get the idea right.... should return a dict
        # with key as the channel name and value as the message to be returned

    # add whichever other methods you want to create

# and after declaring the class
__plugin__ = Wordpress  # the channel name
