Langohr 1.0.0-beta11 Is Released


Langohr is a Clojure RabbitMQ client that embraces AMQP 0.9.1 Model.

1.0.0-beta11 is a development milestone release. We recommend all users to upgrade to it.

Changes between Langohr 1.0.0-beta10 and 1.0.0-beta11


Langohr 1.0.0-beta11 features initial bits of RabbitMQ HTTP API client under langohr.http.

More Convenient TLS Support

Langohr will now automatically enable TLS/SSL if provided :port is 5671.

RabbitMQ Java Client 3.0.x

RabbitMQ Java Client has been upgraded to version 3.0.2. is a new function that performs passive exchange declaration (checks if an exchange exists).

An example to demonstrate:

(require '[  :as lch])
(require '[ :as le])

(let [ch (lch/open conn)]
  (le/declare-passive ch ""))

If the exchange does exist, the function has no effect. If not, an exception (com.rabbitmq.client.ShutdownSignalException, will be thrown.
