This module implements RFC 5322 <https://tools.ietf.org/html/rfc5322>
parser and formatter of email addresses and groups. It parses an input string
from email headers which contain a list of email addresses or a groups of
email addresses (like From, To, Cc, Bcc, Reply-To, Sender, ...). Also it can
generate a string value for those headers from a list of email addresses
objects. Module is backward compatible with RFC 2822
<https://tools.ietf.org/html/rfc2822> and RFC 822
<https://tools.ietf.org/html/rfc822>.
Parser and formatter functionality is implemented in XS and uses
shared code from Dovecot IMAP server.
It is a drop-in replacement for the Email::Address module which
has several security issues. E.g. issue CVE-2015-7686 (Algorithmic
complexity vulnerability)
<https://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2015-7686>, which
allows remote attackers to cause denial of service, is still present in
Email::Address version 1.908.
Email::Address::XS module was created to finally fix
CVE-2015-7686.
Existing applications that use Email::Address module could be
easily switched to Email::Address::XS module. In most cases only changing
"use Email::Address" to
"use Email::Address::XS" and replacing
every "Email::Address" occurrence with
"Email::Address::XS" is sufficient.
So unlike Email::Address, this module does not use regular
expressions for parsing but instead native XS implementation parses input
string sequentially according to RFC 5322 grammar.
Additionally it has support also for named groups and so can be
use instead of the Email::Address::List module.
If you are looking for the module which provides object
representation for the list of email addresses suitable for the MIME email
headers, see Email::MIME::Header::AddressList.
None by default. Exportable functions are:
"parse_email_addresses",
"parse_email_groups",
"format_email_addresses",
"format_email_groups",
"compose_address",
"split_address".
- format_email_addresses
-
use Email::Address::XS qw(format_email_addresses);
my $winstons_address = Email::Address::XS->new(phrase => 'Winston Smith', address => 'winston@recdep.minitrue');
my $julias_address = Email::Address::XS->new(phrase => 'Julia', address => 'julia@ficdep.minitrue');
my @addresses = ($winstons_address, $julias_address);
my $string = format_email_addresses(@addresses);
print $string;
# "Winston Smith" <winston@recdep.minitrue>, Julia <julia@ficdep.minitrue>
Takes a list of email address objects and returns one
formatted string of those email addresses.
- format_email_groups
-
use Email::Address::XS qw(format_email_groups);
my $winstons_address = Email::Address::XS->new(phrase => 'Winston Smith', user => 'winston.smith', host => 'recdep.minitrue');
my $julias_address = Email::Address::XS->new('Julia', 'julia@ficdep.minitrue');
my $users_address = Email::Address::XS->new(address => 'user@oceania');
my $groups_string = format_email_groups('Brotherhood' => [ $winstons_address, $julias_address ], undef() => [ $users_address ]);
print $groups_string;
# Brotherhood: "Winston Smith" <winston.smith@recdep.minitrue>, Julia <julia@ficdep.minitrue>;, user@oceania
my $undisclosed_string = format_email_groups('undisclosed-recipients' => []);
print $undisclosed_string;
# undisclosed-recipients:;
Like
"format_email_addresses" but this
method takes pairs which consist of a group display name and a reference
to address list. If a group is not undef then address list is formatted
inside named group.
- parse_email_addresses
-
use Email::Address::XS qw(parse_email_addresses);
my $string = '"Winston Smith" <winston.smith@recdep.minitrue>, Julia <julia@ficdep.minitrue>, user@oceania';
my @addresses = parse_email_addresses($string);
# @addresses now contains three Email::Address::XS objects, one for each address
Parses an input string and returns a list of
Email::Address::XS objects. Optional second string argument specifies
class name for blessing new objects.
- parse_email_groups
-
use Email::Address::XS qw(parse_email_groups);
my $string = 'Brotherhood: "Winston Smith" <winston.smith@recdep.minitrue>, Julia <julia@ficdep.minitrue>;, user@oceania, undisclosed-recipients:;';
my @groups = parse_email_groups($string);
# @groups now contains list ('Brotherhood' => [ $winstons_object, $julias_object ], undef() => [ $users_object ], 'undisclosed-recipients' => [])
Like "parse_email_addresses"
but this function returns a list of pairs: a group display name and a
reference to a list of addresses which belongs to that named group. An
undef value for a group means that a following list of addresses is not
inside any named group. An output is in a same format as a input for the
function "format_email_groups". This
function preserves order of groups and does not do any de-duplication or
merging.
- compose_address
-
use Email::Address::XS qw(compose_address);
my $string_address = compose_address($user, $host);
Takes an unescaped user part and unescaped host part of an
address and returns escaped address.
Available since version 1.01.
- split_address
-
use Email::Address::XS qw(split_address);
my ($user, $host) = split_address($string_address);
Takes an escaped address and split it into pair of unescaped
user part and unescaped host part of address. If splitting input address
into these two parts is not possible then this function returns pair of
undefs.
Available since version 1.01.
- new
-
my $empty_address = Email::Address::XS->new();
my $winstons_address = Email::Address::XS->new(phrase => 'Winston Smith', user => 'winston.smith', host => 'recdep.minitrue', comment => 'Records Department');
my $julias_address = Email::Address::XS->new('Julia', 'julia@ficdep.minitrue');
my $users_address = Email::Address::XS->new(address => 'user@oceania');
my $only_name = Email::Address::XS->new(phrase => 'Name');
my $copy_of_winstons_address = Email::Address::XS->new(copy => $winstons_address);
Constructs and returns a new
"Email::Address::XS" object. Takes
named list of arguments: phrase, address, user, host, comment and copy.
An argument address takes precedence over user and host.
When an argument copy is specified then it is expected an
Email::Address::XS object and a cloned copy of that object is returned.
All other parameters are ignored.
Old syntax from the Email::Address module is supported too.
Takes one to four positional arguments: phrase, address comment, and
original string. Passing an argument original is deprecated, ignored and
throws a warning.
- parse
-
my $winstons_address = Email::Address::XS->parse('"Winston Smith" <winston.smith@recdep.minitrue> (Records Department)');
my @users_addresses = Email::Address::XS->parse('user1@oceania, user2@oceania');
Parses an input string and returns a list of an
Email::Address::XS objects. Same as the function
"parse_email_addresses" but this one
is class method.
In scalar context this function returns just first parsed
object. If more then one object was parsed then
"is_valid" method on returned object
returns false. If no object was parsed then empty Email::Address::XS
object is returned.
Prior to version 1.01 return value in scalar context is undef
when no object was parsed.
- parse_bare_address
-
my $winstons_address = Email::Address::XS->parse_bare_address('winston.smith@recdep.minitrue');
Parses an input string as one bare email address (addr spec)
which does not allow phrase part or angle brackets around email address
and returns an Email::Address::XS object. It is just a wrapper around
"address" method. Method
"is_valid" can be used to check if
parsing was successful.
Available since version 1.01.
- format
-
my $string = $address->format();
Returns formatted Email::Address::XS object as a string. This
method throws a warning when "user" or
"host" part of the email address is
invalid or empty string.
- is_valid
-
my $is_valid = $address->is_valid();
Returns true if the parse function or method which created
this Email::Address::XS object had not received any syntax error on
input string and also that "user" and
"host" part of the email address are
not empty strings.
Thus this function can be used for checking if
Email::Address::XS object is valid before calling
"format" method on it.
Available since version 1.01.
- phrase
-
my $phrase = $address->phrase();
$address->phrase('Winston Smith');
Accessor and mutator for the phrase (display name).
- user
-
my $user = $address->user();
$address->user('winston.smith');
Accessor and mutator for the unescaped user (local/mailbox)
part of an address.
- host
-
my $host = $address->host();
$address->host('recdep.minitrue');
Accessor and mutator for the unescaped host (domain) part of
an address.
Since version 1.03 this method checks if setting a new value
is syntactically valid. If not undef is set and returned.
- address
-
my $string_address = $address->address();
$address->address('winston.smith@recdep.minitrue');
Accessor and mutator for the escaped address (addr spec).
Internally this module stores a user and a host part of an
address separately. Function
"compose_address" is used for
composing full address and function
"split_address" for splitting into a
user and a host parts. If splitting new address into these two parts is
not possible then this method returns undef and sets both parts to
undef.
- comment
-
my $comment = $address->comment();
$address->comment('Records Department');
Accessor and mutator for the comment which is formatted after
an address. A comment can contain another nested comments in round
brackets. When setting new comment this method check if brackets are
balanced. If not undef is set and returned.
- name
-
my $name = $address->name();
This method tries to return a name which belongs to the
address. It returns either "phrase" or
"comment" or
"user" part of the address or empty
string (first defined value in this order). But it never returns
undef.
- as_string
-
my $address = Email::Address::XS->new(phrase => 'Winston Smith', address => 'winston.smith@recdep.minitrue');
my $stringified = $address->as_string();
This method is used for object stringification. It returns
string representation of object. By default object is stringified to
"format".
Available since version 1.01.
- original
-
my $address = Email::Address::XS->parse('(Winston) "Smith" <winston.smith@recdep.minitrue> (Minitrue)');
my $original = $address->original();
# (Winston) "Smith" <winston.smith@recdep.minitrue> (Minitrue)
my $format = $address->format();
# Smith <winston.smith@recdep.minitrue> (Minitrue)
This method returns original part of the string which was used
for parsing current Email::Address::XS object. If object was not created
by parsing input string, then this method returns undef.
Note that "format" method
does not have to return same original string.
Available since version 1.01.
- stringify
-
my $address = Email::Address::XS->new(phrase => 'Winston Smith', address => 'winston.smith@recdep.minitrue');
print "Winston's address is $address.";
# Winston's address is "Winston Smith" <winston.smith@recdep.minitrue>.
Stringification is done by method
"as_string".
For compatibility with the Email::Address module there are defined some
deprecated functions and variables. Do not use them in new code. Their usage
throws warnings.
Altering deprecated variable
$Email::Address::XS::STRINGIFY changes method which
is called for objects stringification.
Deprecated cache functions
"purge_cache",
"disable_cache" and
"enable_cache" are noop and do
nothing.
