package Font::TTF::Dumper;

=head1 NAME

Font::TTF::Dumper - Debug dump of a font datastructure, avoiding recursion on ' PARENT'

=head1 SYNOPSIS

use Font::TTF::Dumper;
    
    # Print a table from the font structure:
    print ttfdump($font->{$tag});
    
    # Print font table with name
    print ttfdump($font->{'head'}, 'head');
    
    # Print font table with name and other options
    print ttfdump($font->{'head'}, 'head', %opts);

# Print one glyph's data:
    print ttfdump($font->{'loca'}->read->{'glyphs'}[$gid], "glyph_$gid");

=head1 DESCRIPTION

Font::TTF data structures are trees created from hashes and arrays. When trying to figure
out how the structures work, sometimes it is helpful to use Data::Dumper on them. However,
many of the object structures have ' PARENT' links that refer back to the object's parent,
which means that Data::Dumper ends up dumping the whole font no matter what.

The main purpose of this module is to invoke Data::Dumper with a
filter that skips over the ' PARENT' element of any hash.

To reduce output further, this module also skips over ' CACHE' elements and any 
hash element whose value is a Font::TTF::Glyph or Font::TTF::Font object. 
(Really should make this configurable.)

If $opts{'d'}, then set Deepcopy mode to minimize use of crossreferencing.

    $d->Indent(3);  # I want array indicies
    $d->Useqq(1);   # Perlquote -- slower but there might be binary data.

            1
