NAME ^

Games::BonDigi

ABSTRACT ^

This is a crazy experiment in game algorithms and list iterators. And the algorithm to generate BonDigi sequences is quite interesting...

SYNOPSIS ^

    use Games::BonDigi;

    my $iter = Games::BonDigi->sequence();

    while(my $word = $iter->())
    {
        print $word, '!', "\n";
        # Wait for other players...
        sleep(1);
    }

DESCRIPTION ^

This is a crazy, crazy, crazy, crazy, *crazy* module. There is absolutely *no* reason to download it. Please, stay away from it, by any means!

Ok, I've warned you.

If you don't know what Bon-Digi is, you are really lucky.

Actually, this is a quite interesting experiment in software design of clever algorithms. Either I'm stupid or generating the sequence of "Bon" "Digi" words is really much harder than I thought at first.

Try to think of an algorithm and to build *elegant* and *concise* code. You will find that is not so easy...

For any meaning of elegant and concise, of course.

DEDICATION ^

Esteban, I promised to do that... And there it is!

THE GAME ITSELF ^

  This is (did I say it?) rather crazy. I will describe it as an
  RFC and then give you an example.

  BonDigi works with its own internal protocol. The protocol
  consists of a HEADER ("fixed part"), and a PAYLOAD ("the part
  that grows").

  HEADER is *always*: "Bon", "Digi", "Bon", "Digi"

  PAYLOAD is "Bon", "Bon", "Digi", "Digi" (2 repeats the first
  time, then it grows with 3, 4, 5, you get it)

FULL GRAMMAR ^

  <PROTOCOL> := "" | <HEADER> <PAYLOAD> <PROTOCOL>

  <HEADER>   := "Bon" "Digi" "Bon" "Digi"

  <PAYLOAD>  := "Bon" (<n> times) "Digi" (<n> times)
                where <n> grows over time

Mmmh, a recursive stateful grammar. Gets hard. Ok, just kidding...

EXAMPLE ^

Suppose you are ten people in the same room, drinking beers or something. Then someone starts this *crazy* game.

At turn, each of you must say the next word in the sequence. If you say the wrong word, you must drink beer, write Games::BonDigi, make yourself foolish, and so on...

Sequence starts like this:

    Bon, Digi, Bon, Digi, /*header*/, Bon, Bon, Digi, Digi, /*payload x 2*/,
    Bon, Digi, Bon, Digi, /*header*/, Bon, Bon, Bon, Digi, Digi, Digi, /*payload x 3*/
    ...

and you got it. Right?

SEE ALSO ^

I didn't find any serious information about this game on the internet. If you find it, please tell me about.

METHODS ^

new()

Just a class constructor, useless anyway. If you want to use it, please do. Otherwise, you can use class name.

sequence( [$start [,$end [,@words]]] )

Returns an iterator that generates the BonDigi(tm) sequence of words. Without any parameters, the iterator will return words forever, in an endless crazy sequence of BonDigi words.

Parameters are:

$start

Start of repeats sequence. Default is 2. Means that the payload starts by repeating each word $start times.

$end

End of repeats sequence. Just puts a cruel end to insane fun. Why? By default, there's no end. If you set $end, iterator will stop exactly when the payload reaches $end length in repeats.

@words

If you supply your own words, the game won't really be BonDigi anymore. I warned you. Don't do evil.

SUPPORT ^

You are kidding me?
