=head1 NAME

Slackware::Slackget::SpecialFiles::FILELIST - An interface for the special file FILELIST.TXT

=head1 VERSION

Version 1.0.0

=cut

our $VERSION = '1.0.0';

=head1 SYNOPSIS

This class contain all methods for the treatment of the FILELIST.TXT file

    use Slackware::Slackget::SpecialFiles::FILELIST;

    my $spec_file = Slackware::Slackget::SpecialFiles::FILELIST->new('FILELIST.TXT');
    $spec_file->compil();
    my $ref = $spec_file->get_file_list() ;

This class care about package-namespace, which is the root set of a package (slackware, extra or pasture for packages from Slackware)

=head1 WARNINGS

All classes from the Slackware::Slackget::SpecialFiles:: namespace need the followings methods :

	- a contructor new()
	- a method compil()
	- a method get_result(), which one can be an alias on another method of the class.

Moreover, the get_result() methode need to return a hashref. Keys of this hashref are the filenames.

Classes from ths namespace represent an abstraction of the special file they can manage so informations stored in the returned hashref must have a direct link with this special file.

=head1 CONSTRUCTOR

=head2 new

Take a file, a Slackware::Slackget::Config object and an id name :

	my $spec_chk = Slackware::Slackget::SpecialFiles::CHECKSUMS->new('/home/packages/FILELIST.TXT',$config,'slackware');

The constructor return undef if the file does not exist.

=cut

sub new
{
	my ($class,$file,$config,$root) = @_ ;
	return undef if(!defined($config) && ref($config) ne 'Slackware::Slackget::Config') ;
	my $self={};
	$self->{ROOT} = $root;
	$self->{config}=$config;
	return undef unless(defined($file) && -e $file);
# 	print "[debug FILELIST] Loading $file as FILELIST\n";
	$self->{FILE} = new Slackware::Slackget::File ($file,'file-encoding' => $config->{common}->{'file-encoding'});
	$self->{DATA} = {};
	bless($self,$class);
	return $self;
}

=head1 FUNCTIONS

=head2 compile

This method take no arguments, and extract the list of couple (file/package-namespace). Those couple are store into an internal data structure.

	$list->compile();

=head2 to_XML (deprecated)

Same as to_xml(), provided for backward compatibility.

=head2 to_xml

return a string containing all packages name carriage return separated.

WARNING: ONLY FOR DEBUG

	my $string = $list->to_xml();

=cut

=head2 meta_to_XML (deprecated)

Same as meta_to_xml(), provided for backward compatibility.

=cut

sub meta_to_XML {
	return meta_to_xml(@_);

=head2 meta_to_xml

Return an XML encoded string which represent the meta informations of the FILELIST.TXT file.
