NAME

Games::ABC_Path::Solver::Board - handles an ABC Path board.

VERSION

Version 0.3.2

SYNOPSIS

    use strict;
    use warnings;

    my $board_fn = shift(@ARGV);

    if (!defined ($board_fn))
    {
        die "Filename not specified - usage: abc-path-solver.pl [filename]!";
    }

    my $solver = Games::ABC_Path::Solver::Board->input_from_file($board_fn);
    # Now let's do a neighbourhood inferring of the board.

    $solver->solve;

    foreach my $move (@{$solver->get_moves})
    {
        print +(' => ' x $move->get_depth()), $move->get_text(), "\n";
    }

FUNCTIONS

new

The constructor.

get_successful_layouts()

Returns a copy of the successful layouts. Each one of them is a completed Games::ABC_Path::Solver::Board object.

$board->get_possible_letters_for_cell($x,$y)

Returns an array reference of the possible letters for the cell ($x,$y) where $x and $y are in the range 0..4 and the letters are their letter names.

$board->solve()

Performs the actual solution. Should be called after input.

$self->get_successes_text_tables()

This returns a textual representation of the successful layouts.

my $board = Games::ABC_Path::Solver::Board->input_from_file($filename)

Inputs the board from the $filename file path containing a representation of the initial board.

Sample boards can be found in the distribution under t/layouts/ .

Here is the description of their formats. The first line should be the magic string ABC Path Solver Layout Version 1: , and the next line should be a row of 7 letters, the first being a hint for the top-left-to-bottom-right perpendicular, the last being a hint for the top-right-to-bottom-left perpendicular and the rest of the letters being vertical hints.

After that, there are 5 rows of horizontal hints being a letter, 5 spaces and another letter. On one of the squares one can put a letter instead of a space, to indicate it must be there.

The last row is another row of vertical hints and perpendicular hints.

my $board = Games::ABC_Path::Solver::Board->input_from_v1_string($layout_string)

This is a class method that inputs a version 1 string (as specified in input_from_file only without the opening magic line.)

$board->get_moves()

Returns the moves performed by the board. Each move is an object of a Games::ABC_Path::Solver::Move sub-class.
