spade_bdi 0.3.0

Features

• Create agents that parse and execute an ASL file written in AgentSpeak.

• Supports Agentspeak-like BDI behaviours.

• Add custom actions and functions.

• Send TELL, UNTELL and ACHIEVE KQML performatives.

Examples

basic.py:

import getpass
from spade_bdi.bdi import BDIAgent

server = input("Please enter the XMPP server address: ")
password = getpass.getpass("Please enter the password: ")

a = BDIAgent("BasicAgent@" + server, password, "basic.asl")
a.start()

a.bdi.set_belief("car", "blue", "big")
a.bdi.print_beliefs()

print(a.bdi.get_belief("car"))
a.bdi.print_beliefs()

a.bdi.remove_belief("car", 'blue', "big")
a.bdi.print_beliefs()

print(a.bdi.get_beliefs())
a.bdi.set_belief("car", 'yellow')

basic.asl:

!start.

+!start <-
    +car(red);
    .a_function(3,W);
    .print("w =", W);
    literal_function(red,Y);
    .print("Y =", Y);
    .custom_action(8);
    +truck(blue).

+car(Color)
 <- .print("The car is ",Color).
