NAME

       Games::Go::Dg2ASCII - Perl extension to convert Games::Go::Diagrams to ASCII diagrams

SYNOPSIS

       use Games::Go::Dg2ASCII

        my $dg2ascii = B<Games::Go::Dg2ASCII-E<gt>new> (options);
        my $ascii = $dg2ascii->convertDiagram($diagram);

DESCRIPTION

       A Games::Go::Dg2ASCII object converts a Games::Go::Diagram object into ASCII diagrams.

METHODS

       my $dg2ascii = Games::Go::Dg2ASCII->new (?options?)
           A new Games::Go::Dg2ASCII takes the following options:

   General Dg2 Converter Options:
       boardSize => number
           Sets the size of the board.

           Default: 19

       doubleDigits => true | false
           Numbers on stones are wrapped back to 1 after they reach 100.  Numbers associated with
           comments and diagram titles are not affected.

           Default: false

       coords => true | false
           Generates a coordinate grid.

           Default: false

       topLine     => number (Default: 1)
       bottomLine  => number (Default: 19)
       leftLine    => number (Default: 1)
       rightLine   => number (Default: 19)
           The edges of the board that should be displayed.  Any portion of the board that
           extends beyond these numbers is not included in the output.

       diaCoords => sub { # convert $x, $y to Games::Go::Diagram coordinates }
           This callback defines a subroutine to convert coordinates from $x, $y to whatever
           coordinates are used in the Games::Go::Diagram object.  The default diaCoords converts
           1-based $x, $y to the same coordinates used in SGF format files.  You only need to
           define this if you're using a different coordinate system in the Diagram.

           Default:
               sub { my ($x, $y) = @_;
                     $x = chr($x - 1 + ord('a')); # convert 1 to 'a', etc
                     $y = chr($y - 1 + ord('a'));
                     return("$x$y"); },           # concatenate two letters

       file => 'filename' | $descriptor | \$string | \@array
           If file is defined, the ASCII diagram is dumped into the target.  The target can be
           any of:

           filename
               The filename will be opened using IO::File->new.  The filename should include the
               '>' or '>>' operator as described in 'perldoc IO::File'.  The ASCII diagram is
               written into the file.

           descriptor
               A file descriptor as returned by IO::File->new, or a \*FILE descriptor.  The ASCII
               diagram is written into the file.

           reference to a string scalar
               The ASCII diagram is concatenated to the end of the string.

           reference to an array
               The ASCII diagram is split on "\n" and each line is pushed onto the array.

           Default: undef

       print => sub { my ($dg2ascii, @lines) = @_; ... }
           A user defined subroutine to replace the default printing method.  This callback is
           called from the print method (below) with the reference to the Dg2ASCII object and a
           list of lines that are part of the ASCII diagram lines.

       $dg2tex->configure (option => value, ?...?)
           Change Dg2TeX options from values passed at new time.

       $dg2ascii->print ($text ? , ... ?)
           prints the input $text directly to file as defined at new time.  Whether or not file
           was defined, print accumulates the $text for later retrieval with converted.

       my $ascii = $dg2ascii->converted ($replacement)
           Returns the entire ASCII diagram converted so far for the Dg2ASCII object.  If
           $replacement is defined, the accumulated ASCII is replaced by $replacement.

       $dg2ascii->comment ($comment ? , ... ?)
           Inserts the comment character (which is nothing for ASCII) in front of each line of
           each comment and prints it to file.

       my $dg2ascii->convertDiagram ($diagram)
           Converts a Games::Go::Diagram into ASCII.  If file was defined in the new method, the
           ASCII is dumped into the file.  In any case, the ASCII is returned as a string scalar.

       my $ascii = $dg2ascii->convertText ($text)
           Converts $text into ASCII code - gee, that's not very hard.  In fact, this method
           simply returns whatever is passed to it.  This is really just a place-holder for more
           complicated converters.

           Returns the converted text.

       $title = $dg2ascii->convertProperties (\%sgfHash)
           convertProperties takes a reference to a hash of properties as extracted from an SGF
           file.  Each hash key is a property ID and the hash value is a reference to an array of
           property values: $hash->{propertyId}->[values].  The following SGF properties are
           recognized:

           GN GameName
           EV EVent
           RO ROund
           PW PlayerWhite
           WR WhiteRank
           PB PlayerBlack
           BR BlackRank
           DT DaTe
           PC PlaCe
           GC GameComment
           KM KoMi
           RE REsult
           TM TiMe

           Both long and short property names are recognized, and all unrecognized properties are
           ignored with no warnings.  Note that these properties are all intended as game-level
           notations.

       $dg2ascii->close
           prints any final text to the diagram (currently none) and closes the dg2ascii object.
           Also closes file if appropriate.
