Mode: Operational Mode


ranged is only valid for numeric types, it limits the valid range of input values.

Both boundaries need to be explicitly specified and the limits are inclusive.

An added benefit is that it automatically prompts the user the valid range in its help message.


            command newbie {
                help "Show newbie";

                argument age-group {
                    help "Check user age group";
                    type ranged uint 0 .. 100;


        user@router> show example newbie age-group ?
        Possible completions:
          <age-group>          Check user age group (0..100)
        user@router> show example newbie age-group 33 

        user@router> show example newbie age-group 101   
        value 101 is not within range (0..100) at '101'
