Hi, I am pleased to announce the first public release of Zinc WebSockets, an implementation of client and server RFC 6455 regular (ws://) and secure (wss://) WebSockets on top of Zinc HTTP Components and Zodiac TLS/SSL Streams.
High level documentation can be found here: https://github.com/svenvc/docs/blob/master/zinc/zinc-websockets-paper.md The code can be found in the regular Zinc repositories, or can be loaded using Metacello: ConfigurationOfZincHTTPComponents project latestVersion load: 'WebSocket'. Three examples are included and explained in the high level documentation: 1. a trivial echo service - each incoming message is simply echoed back to the client 2. a simple chatroom - each client opens a web socket to the chatroom service running on the server - the server keeps track of all connected client web sockets - when a message comes in from any client it is distributed to all clients - each client shows all incoming messages 3. a simple, continously updated status view - a client connects and listens for incoming messages containing a status report - the server streams status reports to each connected client every second - in the web browser you get to see the Smalltalk image's clock, memory and process stats Tested and approved on 2.0 #281. Portability to 1.3 and 1.4 should be OK. The implementation of Zinc WebSockets was made possible in part through financial backing by Andy Burnett of Knowinnovation Inc. and ESUG. Thanks!
