MVpybot: Update 2

Monday, January 18th, 2010

I just did another major update to MVpybot. Listeners have been implemented. A listener is a function that gets called whenever the bot receives data, or it can be set to only be called when a certain type (privmsg, join, part, etc) is received. As usual, the source is at the SVN repo.

Now for the technical stuff. A listener is just a python file in the listeners folder, with functions defined in it. A function’s name should be botfunction_type, where type is the type of message to listen for (privmsg, join, part, etc) or it can be ‘any’ for all data received by the bot. Here is an example logger function:


import time


timestamp=time.strftime('[ Session starting at %y-%m-%d %H:%M:%S ]')

def botfunction_any():
 timestamp=time.strftime('[%y-%m-%d %H:%M:%S] ')

As you can see from the example, plugins can be quickly enabled or disabled by toggling the ‘enabled’ flag. Also, ‘line’ is passed to the plugin. Not that anything outside of function definitions will be run when the bot starts.

Listeners can use the ‘socket’ variable to send data to the server, as shown in this example:



def botfunction_privmsg():
 print "called"
 out="PRIVMSG %s :Botfunction_privmsg called" %(channel)
 print out

Note that in the example, it uses botfunction_privmsg. To make listeners easier to write, the main program will automatically figure out these variables from privmsgs and pass them to the function:

info         #user info
msg          #the message
channel      #the channel the message was from (set to the sender for private messages)
sender       #the sender of the message
senderstuff  #info of the sender
isprivate    #whether or not the message was a private message as opposed to a channel message.

This only applies to privmsgs. All other events only get ‘socket’ and ‘line’ passed and have to figure out everything from ‘line’

That’s all for now.

MVpybot: Update

Tuesday, December 22nd, 2009

Well, i’ve finally gotten around to putting out some decent source for the bot. Here it is. There is also an addon system. To make an addon, simply make a python file in the botplugins/ folder and put your code in, like this:


def test():
 return("PRIVMSG %s :test" %(channel))

This would make a function called test. The variables channel, sender, nick, cmd, and run are passed to the function. The functions syscmd() and getlevel() are also passed to the plugin.

The default plugins that are included with the bot are ping, for pinging addresses, testplugin, for testing the bot, yacas, for doing math with yacas (delete it if you don’t have yacas installed) and getlevel, for demonstrating the ability to use the getlevel function in a plugin.

I have also set up a page for the bot, see the links bar below the logo.

Python IRC Bot in the Works

Saturday, December 5th, 2009

*** Update ***: Main page for bot here

I am currently writing a small, fast, small-footprint IRC bot in Python. More details as I finish the bot. The functions created so far:

  • Help (Displays Help)
  • Echo (Echo back a message)
  • Say (Send a message to a channel)
  • Spam (Send a message to a channel a specified amount of times)
  • Join (Join a channel)
  • Part (Part a channel)
  • Authorization (username+password)
  • Deauthorization
  • User lookup
  • Raw (Use raw IRC commands)
  • Uptime (Display uptime)
  • Math (Do math functions with Yacas)

Planned functions:

  • Encrypted passwords
  • Data storage, either in a text file or a MySQL DB
  • Channel mode control

This bot is not meant to be a complex bot, it is intended to be a fast, light bot that can be easily reprogrammed.
