Package ecpush is a package for subscribing to real-time meteorological data feeds from Environment Canada. The main goal of ecpush is to provide a simple and lightweight client that can be used for receiving real-time data events directly from Environment Canada's meteorological product feed. The client can directly fetch the published products, or it can just provide a notification channel containing the product location (HTTP URL to Environment Canada's Datamart). The client has also been designed to automatically recover from any connection or channel interruptions. To create a new client, create a Client struct. The only required field is the Subtopics array. Default values for other fields are listed in the struct definition. An example configuration is shown below (subscribing text bulletins, citypage XML and CAP alert files). Please see https://github.com/MetPX/sarracenia/blob/master/doc/sr_subscribe.1.rst#subtopic-amqp-pattern-subtopic-need-to-be-set for formatting subtopics. Calling Connect(ctx) will return an error if no subtopics are provided. The function will block until the initial connection with the remote server is established. When the client is provisioned, an internal Goroutine is created to consume the feed. To consume the events, call Consume() on the client. This returns an Event and an indicator if the client is still actively consuming from the remote server. To close the client, call the cancel function on the context provided to the client. This will gracefully close the active channels and connection to the remote server. A fully functioning client can be found in the example directory. I would like to thank Sean Treadway for his Go RabbitMQ client package. I would also like to thank Environment Canada and the awesome people at Shared Services Canada for their developments and "openness" of MetPX and sarracenia. Copyright (c) 2019 Tanner Ryan.
