NAME

Net::LibIDN2 - Perl 6 bindings for GNU LibIDN2

SYNOPSIS

    use Net::LibIDN2;

    my $idn := Net::LibIDN2.new;

    my Int $code;
    my $ulabel := "m\xFC\xDFli";
    my $alabel := $idn.lookup_u8($ulabel, IDN2_NFC_INPUT, $code);
    say "$alabel $code"; # xn--mli-5ka8l 0

    my $result := $idn.register_u8($ulabel, $alabel, IDN2_NFC_INPUT, $code);
    say "$result $code"; # xn--mli-5ka8l 0
    say $idn.strerror($code);      # success
    say $idn.strerror_name($code); # IDN2_OK

DESCRIPTION

Net::LibIDN2 is a Perl 6 wrapper for the GNU LibIDN2 library.

METHODS

Compares $version against the version of LibIDN2 installed and returns either an empty string if $version is greater than the version installed, or IDN2_VERSION otherwise.

Returns the error represented by $errno in human readable form.

Returns the internal error name of $errno.

Converts a UTF8 encoded string $input to ASCII and returns the output. $code, if provided, is assigned to IDN2_OK on success, or another error code otherwise. Requires LibIDN2 v2.0.0 or greater.

Converts an ACE encoded domain name $input to UTF8 and returns the output. $code, if provided, is assigned to IDN2_OK on success, or another error code otherwise. Requires LibIDN v2.0.0 or greater.

Performs an IDNA2008 lookup string conversion on $input. See RFC 5891, section 5. $input must be a UTF8 encoded string in NFC form if no IDN2_NFC_INPUT flag is passed.

Performs an IDNA2008 register string conversion on $uinput and $ainput. See RFC 5891, section 4. $uinput must be a UTF8 encoded string in NFC form if no IDN2_NFC_INPUT flag is passed. $ainput must be an ACE encoded string.

CONSTANTS

The maximum label length.

The maximum domain name length.

VERSIONING

The minor version of LidIDN2 installed.

The patch version of LibIDN2 installed.

Label is larger than IDN2_LABEL_MAX_LENGTH.

Invalid A-label.

Given U-label and A-label do not match.

Invalid combination of flags.

String is not normalized in NFC format.

String has forbidden two hyphens.
