Rope is a public Kite registry with proxy support between kites. Also introduces bi-directional communication between Kites.
Before starting make sure to call npm install and go get github.com/koding/kite if you want to try go example. Then to start Rope server;
$ node rope.js
This will start the server on 0.0.0.0:8080 which then you can run one of the node examples (in another terminal session);
$ node rope-node.js
will create a Rope Node with Node.js, same file also supports browsers which you can try it out;
$ open rope-browser.html
will load the kite.js bundle and then runs the rope-node.js which will create another Rope Node in the browser this time.
To try another Rope Node in Go this time;
$ go run rope-node.go
Which will do the same with others.
Once ready, you can start playing with nodes by calling run over Rope Server. The best way to do that for now opening Dev Console in your choice of Browser after loading the rope-browser.html. Which will connect to Rope Server, identifies itself and will get a list of Kites registered before which you can access from publicKites global variable. There will be another public variable called kite which will allow you to interact with Rope Server. And for an example of usage of run over Rope Server would be (in Dev Console of rope-browser.html);
> kite.tell('run', {kiteId: publicKites[0], method: "kite.ping"}).then(console.log.bind(console))
pong
will ping the first public kite which will end with a simple pong
> kite.tell('run', {kiteId: publicKites[0], method: "kite.systemInfo"}).then(console.log.bind(console))

will return the system info from first public kite.
> kite.tell('run', {kiteId: publicKites[0], method: "kite.prompt", args: ["Your Name? "]}).then(console.log.bind(console))
# on the terminal of first public kite you will see the prompt "Your Name? "
λ go run rope-node.go
