NAME ^

IO::Socket::SSL::PublicSuffix - provide access to Mozillas list of effective TLD names

SYNOPSIS ^

    # use builtin default
    use IO::Socket::SSL::PublicSuffix;
    $ps = IO::Socket::SSL::PublicSuffix->default;

    # load from string
    $ps = IO::Socket::SSL::PublicSuffix->from_string("*.uk\n*");

    # load from file or file handle
    $ps = IO::Socket::SSL::PublicSuffix->from_file($filename);
    $ps = IO::Socket::SSL::PublicSuffix->from_file(\*STDIN);


    # --- string in -> string out
    # $rest -> whatever.host
    # $tld  -> co.uk
    my ($rest,$tld) = $ps->public_suffix('whatever.host.co.uk');
    my $tld = $ps->public_suffix('whatever.host.co.uk');

    # $root_domain -> host.co.uk
    my $root_domain = $ps->public_suffix('whatever.host.co.uk', 1);

    # --- array in -> array out
    # $rest -> [qw(whatever host)]
    # $tld  -> [qw(co uk)]
    my ($rest,$tld) = $ps->public_suffix([qw(whatever host co uk)]);

    # To update this file with the current list:
    perl -MIO::Socket::SSL::PublicSuffix -e 'IO::Socket::SSL::PublicSuffix::update_self_from_url()'

DESCRIPTION ^

This module uses the list of effective top level domain names from the mozilla project to determine the public top level domain for a given hostname.

Method

class->default(%args)

Returns object with builtin default. min_suffix can be given in %args to specify the minimal suffix, default is 1.

class->from_string(string,%args)

Returns object with configuration from string. See method default for %args.

class->from_file( file name| file handle, %args )

Returns object with configuration from file or file handle. See method default for %args.

$self->public_suffix( $host|\@host, [ $add ] )

In array context the function returns the non-tld part and the tld part of the given hostname, in scalar context only the tld part. It adds $add parts of the non-tld part to the tld, e.g. with $add=1 it will return the root domain.

If there were no explicit matches against the public suffix configuration it will fall back to a suffix of length 1.

The function accepts a string or an array-ref (e.g. host split by .). In the first case it will return string(s), in the latter case array-ref(s).

International hostnames or labels can be in ASCII (IDNA form starting with xn--) or unicode. In the latter case an IDNA handling library like Net::IDN:::Encode, Net::LibIDN or recent versions of URI need to be installed.

($self|class)->can_idn

Returns true if IDN support is available.

BUGS ^

 Q: Why yet another module, we already have L<Domain::PublicSuffix> and
    L<Mozilla::PublicSuffix>.
 A: Because the public suffix data change more often than these modules do,
    IO::Socket::SSL needs this list and it is more easy this way to keep it
    up-to-date.
