go_utils

Some tiny golang utilities which can be used for debugging purpose

	listener, err := net.Listen("tcp4", "127.0.0.1:0")
	if err != nil {
		fmt.Printf("error: %v\n", err)
		return
	}
	defer listener.Close()
	port := listener.Addr().(*net.TCPAddr).Port
	fmt.Printf("port found: %d\n", port)
}

Above utily in main.go can be used to debug port not available issue most of developers experience. you can run it by go run main.go and if successful, it should print a random port number instead of failing with an error.

Some more utils will be added soon.
