43KNlxM - Games::Cards::Poker.pm created by Pip Stuart to provide Poker functions (&& maybe later objects) using only Perl. NAME Games::Cards::Poker - Perl Poker functions VERSION This documentation refers to version 1.0.44F2Q8F of Games::Cards::Poker, which was released on Thu Apr 15 02:26:08:15 2004. SYNOPSIS use Games::Cards::Poker; # Deal 4 players hands && score them... my $players = 4; # number of players to get hands dealt my $hand_size = 5; # number of cards to deal to each player my @hands = ();# player hand data my @deck = Shuffle(Deck()); # Deck returns array of ('As'..'2c') #print "Deck:@deck\n"; # print out shuffled deck for(my $pndx = 0; $pndx < $players; $pndx++) { for(my $hndx = 0; $hndx < $hand_size; $hndx++) { push(@{$hands[$pndx]}, pop(@deck)); # $hands[$pndx][$hndx] = pop } printf("Player%d score:%4d hand:@{$hands[$pndx]}\n", $pndx, ScoreHand(@{$hands[$pndx]})); } DESCRIPTION Poker provides a few simple functions for creating decks of cards && manipulating them for simple Poker games or simulations. 2DO - mk HandScore to take score && return proper hand - mk ScoreHand take optional arrayref param like others - mk up data file format - better error checking - What else does Poker need? USAGE Deck() Returns a new array of scalars with the abbreviated Poker names of cards (eg. As == Ace of Spades, Td == Ten of Diamonds, 2c == Two of Clubs, etc.). Shuffle(@cards) Shuffles the passed in @cards array in one quick pass. Shuffle() returns a shuffled copy of the @cards array. Shuffle() can also take an arrayref parameter instead of an explicit @cards array in which case, the passed in arrayref will be shuffled in place && the return value need not be reassigned. SortCards(@cards) Sorts the passed in @cards array. SortCards() returns a sorted copy of the @cards array. SortCards() can also take an arrayref parameter instead of an explicit @cards array in which case, the passed in arrayref will be sorted in place && the return value need not be reassigned. ShortHand(@hand) Returns a scalar string containing the abbreviated Poker description of @hand (eg. AKQJTs == Royal Flush, QQ993 == Two Pair, etc.). ScoreHand(@hand) Returns an integer score (where lower is better) for the passed in Poker @hand. This means 0 (zero) is returned for a Royal Flush && the worst possible score is 7460 awarded to 7, 5, 4, 3, 2 unsuited. If you want higher scores to mean higher hands, just subtract the return value from 7460. All suits are considered to have equal value in this scoring function. It should be easy to use ScoreHand() as a first pass where ties can be resolved by another suit-comparison function if you want such behavior. NOTES Games::Poker::* wouldn't compile correctly for me so I thought it shouldn't take too long to write my own. =) Suits are: s,h,d,c (Spade,Heart,Diamond,Club) like bridge (alphabetical) although they are sorted && appear in this order, suits are ignored for scoring by default (but can be optionally reordered && scored later) B64 notes: Cards map perfectly into A..Z,a..z so += 10 for only letter rep B64 Cards: 0.As 4.Ks 8.Qs C.Js G.Ts K.9s O.8s S.7s W.6s a.5s e.4s i.3s m.2s 1.Ah 5.Kh 9.Qh D.Jh H.Th L.9h P.8h T.7h X.6h b.5h f.4h j.3h n.2h 2.Ad 6.Kd A.Qd E.Jd I.Td M.9d Q.8d U.7d Y.6d c.5d g.4d k.3d o.2d 3.Ac 7.Kc B.Qc F.Jc J.Tc N.9c R.8c V.7c Z.6c d.5c h.4c l.3c p.2c Values: 0 1 2 3 4 5 6 7 8 9 A B C B64 Cards: 0.As 1.Ah 2.Ad 3.Ac Values: 0 4.Ks 5.Kh 6.Kd 7.Kc 1 8.Qs 9.Qh A.Qd B.Qc 2 C.Js D.Jh E.Jd F.Jc 3 G.Ts H.Th I.Td J.Tc 4 K.9s L.9h M.9d N.9c 5 O.8s P.8h Q.8d R.8c 6 S.7s T.7h U.7d V.7c 7 W.6s X.6h Y.6d Z.6c 8 a.5s b.5h c.5d d.5c 9 e.4s f.4h g.4d h.4c A i.3s j.3h k.3d l.3c B m.2s n.2h o.2d p.2c C q.Jok0 r.Jok1 -1 Error checking is minimal.
