xmpp-clj allows you to write simple jabber bots in idiomatic clojure by providing a lightweight wrapper around the smack library.
[xmpp-clj "0.3.1"]
Create a temporary jabber account for your bot. I've used gmail here, but there are a bunch of free providers
Create a leiningen project and cd into the project directory
lein new mybot
cd ./mybot
Add xmpp-clj to your deps (project.clj):
(defproject mybot "0.1.0"
:description "FIXME: write"
:dependencies [[xmpp-clj "0.3.1"]])
Open up src/mybot/core.clj and require the xmpp lib:
(ns mybot.core
(:require [xmpp-clj :as xmpp]))
Define a handler and start the bot. Handlers accept a single parameter
-- the message map -- and should return a string with a message back
to the sender. Return nil to omit a response. Here's a very simple
example:
;; This bot always responds with the message 'Ermahgerd!!!'
(xmpp/start-bot :username "[email protected]"
:password "clojurebot12345"
:host "talk.google.com"
:domain "gmail.com"
:handler (fn [m] "Ermahgerd!!!")
Next, fire up your chat client, add your new bot buddy, and send him / her a message. The response should look someting like this:
me: hello chatbot
chatbot: Ermahgerd!!!
;; Stop the bot when you're done:
(xmpp/stop-bot)
;; You can use a name to start / stop multiple bots in the same
;; process:
(xmpp/start-bot :name :bot1
:username ...)
(xmpp/start-bot :name :bot2
:username ...)
(xmpp/stop-bot :bot1)
(xmpp/stop-bot :bot2)
;; And names can be any value / object:
(xmpp/start-bot :name 0
:username ...)
(xmpp/start-bot :name 1
:username ...)
See the src/xmpp_clj/examples folder for additional examples. If
you'd like to manually manage connections, see the xmpp-clj.bot
namespace.
