NAME

Games::SGF::Util - Utility pack for Games::SGF objects

VERSION

Version 0.991

SYNOPSIS

Quick summary of what the module does.

Perhaps a little code snippet.

    use Games::SGF::Util;

    my $util = new Games::SGF::Util($sgf);
    
    $util->filter( "C", undef ); # removes all comments from SGF

DISCRIPTION

This is a collection of useful methods for manipulating a Games::SGF object.

METHODS

new

  $util = new Games::SGF::Util($sgf);

This initializes a new Games::SGF::Util object. Will return undef if $sgf is no supplied.

touch

  $util->touch(\&sub);

This will call &sub for every node in $sgf. &sub will be passed the $sgf object. any subroutines which manipulate the $sgf tree will lead to undefined behavior. The safe methods to use are:

"property" in Games::SGF
"getProperty" in Games::SGF
"setProperty" in Games::SGF
"isCompose" in Games::SGF
"isStone" in Games::SGF
"isMove" in Games::SGF
"isPoint" in Games::SGF
"compose" in Games::SGF
"stone" in Games::SGF
"move" in Games::SGF
"point" in Games::SGF
"err" in Games::SGF

filter

  $util->fiter( $tag, \&sub);

Will call &sub for every $tag which is in $sgf. &sub will be passed the tag value. The value then be reset to the return of &sub. If the return is "" the tag will be unset.

If the tag has a value list each value will be sent to $callback.

If the $callback returns undef it will not be set.

Example:

  # removes all comments that don't match m/Keep/
  $util->filter( "C", sub { return $_[0] =~ m/Keep/ ? $_[0] : ""; );

sgf

   $sgf = $util->sgf;
   $sgf = $util->sgf($sgf)

This returns a clone of the $sgf object associated with $util, or sets the $sgf object to a clone of object supplied.
