wactbprot / vl-tcp

vl-tcp

Collection of functions for TCP interaction.

changes

• 1.0.x ** renamed read-* functions to rd-* in order to avoid clojure.core/read-line collision

• 2.0.x ** renamed write-* functions to wrt-* ** gen socket with timeout option (defaults to 60s) ** add logo to repo

• 2.0.8 ** default socket timeout set to 10min

Examples/ Tests

Server

Start a echo server in tcp-test-server.

(in-ns 'wactbprot.tcp-test-server)

(def srv (server))

Shut down the server by:

(reset! srv false)

Afterwards the server responses one more time.

NOTE: The echo server is not exactly an echo server. The read and write functions manipulate the message sent (see e.g. rd function description).

Client

After the server is started one can play around with different wrt and rd functions. Run the client functions in the wactbprot.vl-tcp namespace. Best: run a second REPL:

(in-ns 'wactbprot.vl-tcp)
	
(with-open [sock (gen-socket "localhost" 9999)
             in-sock (in-socket sock) 
			 out-sock (out-socket sock)] 
	(wrt-bytes out-sock "foo\r") 
	(Thread/sleep 20) 
	(prn (rd-eot in-sock -1)))

(with-open [sock     (gen-socket "localhost" 9999)
            in-sock  (in-socket sock)
            out-sock (out-socket sock)]
    (wrt-bytes out-sock "foo\r")
    (Thread/sleep 20)
    (prn (rd-line in-sock)))
