Sample use:

func CommandPuts(i *picol.Interp, argv []string, pd interface{}) (string, error) {
	if len(argv) != 2 {
		return "", fmt.Errorf("Wrong number of args for %s %s", argv[0], argv)
	}
	fmt.Println(argv[1])
	return "", nil
}
...
	interp := picol.InitInterp()
	// add core functions
	interp.RegisterCoreCommands()
	// add user function
	interp.RegisterCommand("puts", CommandPuts, nil)
	// eval
	result, err := interp.Eval(string(buf))
	if err != nil {
		fmt.Println("ERROR", err, result)
	} else {
		fmt.Println(result)
	}
