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)) See further examples under the directory examples ( https://github.com/mdjurfeldt/guile-mqqt/tree/main/examples).
