[ANN] guile-mqtt-0.1.1 released

[ANN] guile-mqtt-0.1.1 released

[Mikael Djurfeldt]

Guile MQTT provides bindings for the libmosquitto MQTT client
library. The bindings are written in GOOPS
(https://www.gnu.org/software/guile/manual/html_node/GOOPS.html)
and rely on lower-level bindings created by NYACC directly and
automatically from mosquitto.h.

This release adds support for new options in connect:

#:bind-address #:tls-cafile #:tls-capath #:tls-certfile #:tls-keyfile
The guile-mqqt bindings align with GOOPS style, which means short
method names. (The specialization is done through the arguments.)

The user can extend the client class by inheritance.

Example:

This example, as well as the Guile libmosquitto bindings themselves,
are inspired by the Chicken Scheme mosquitto bindings
(http://wiki.call-cc.org/eggref/5/mosquitto) by Dmitrii Kosenkov.

(use-modules (mosquitto client))

(let ((client (make-client #:on-connect
                          (lambda (client err)
                            (if (not (eq? err MOSQ_ERR_SUCCESS))
                                (abort err)
                                (display "Yay, we are connected!"))))))
  (set! (disconnect-callback client)
        (lambda (client err)
          (if (not (eq? err MOSQ_ERR_SUCCESS))
            (display "Unexpected disconnect..."))))

  (set! (message-callback client)
        (lambda (cl msg)
          (display (string->append "Topic: " (topic msg)
                                   "Payload:" payload msg))
          (publish client "topic2" "message received, thanks!")))
  (connect client "localhost" #:username "mqtt-admin" #:password "mypass")
  (subscribe client "topic1")
  (loop-forever client))
