Sample Code

// Slice definitions (Greeter.ice)

module VisitorCenter
{
    /// Represents a simple greeter.
    interface Greeter
    {
        /// Creates a personalized greeting.
        /// @param name The name of the person to greet.
        /// @return The greeting.
        string greet(string name);
    }
}

# Client application (main.py)

        greeting = await greeter.greetAsync(getpass.getuser())
        print(greeting)

        adapter.activate()
        print("Listening on port 4061...")

        try:
            communicator.waitForShutdown()
        except KeyboardInterrupt:
