chat-client

A Clojure library designed to communicate with the chat-server.

Usage

Require the client library in your namespace:

(nsmyns
(:require [chat-client.core :as client]))

Create a new socket connection by calling the create function. This will return a map containing the keys :socket, :reader, and :writer.

(defsocket (create"localhost"1234))

We can now create a thread for reading messages from the server by passing it the socket map and a handler function that will be responsible for processing the incoming messages.

(defout (atom []))
(defnmessage-handler [out]
(fn [message]
(swap! out conj message)))
(start-reader-thread socket (message-handler out)) 

Above, we create an atom to stored the messages we've received so far and a message handler function that will be used to populate it. The function is a closure that returns the handler. We'll initialize it with the out atom and pass it to the start-reader-thread function.

We can send messages to the socket using the send-message function and close the socket using the close function when we're finished.

(send-message socket "USER Bob")
(send-message socket "MSG Hi")
(send-message socket "LIST")
(send-message socket "MSG Bye") (close socket)
(println @out)
