NAME Email::Address - RFC 2822 Address Parsing and Creation SYNOPSIS use Email::Address; my @addresses = Email::Address->parse($line); my $address = Email::Address->new(Casey => 'casey@localhost'); print $address->format; DESCRIPTION This class implements a complete RFC 2822 parser that locates email addresses in strings and returns a list of "Email::Address" objects found. Alternatley you may construct objects manually. The goal of this software is to be correct, and very very fast. Package Variables Several regular expressions used in this package are useful to others. For convenience, these variables are declared as package variables that you may access from your program. These regular expressions conform to the rules specified in RFC 2822. You can access these variables using the full namespace. If you want short names, define them yourself. my $addr_spec = $Email::Address::addr_spec; $Email::Address::addr_spec This regular expression defined what an email address is allowed to look like. $Email::Address::angle_addr This regular expression defines an $addr_spec wrapped in angle brackets. $Email::Address::name_addr This regular expression defines what an email address can look like with an optional preceeding display name, also known as the "phrase". $Email::Address::mailbox This is the complete regular expression defining an RFC 2822 emial address with an optional preceeding display name and optional following comment. Class Methods parse my @addrs = Email::Address->parse( q[me@local, Casey , "Casey" (West)] ); This method returns a list of "Email::Address" objects it finds in the input string. The specification for an email address allows for infinitley nestable comments. That's nice in theory, but a little over done. By default this module allows for five (5) levels of nested comments. If you think you need more, modify the $Email::Address::COMMENT_NEST_LEVEL package variable to allow more. $Email::Address::COMMENT_NEST_LEVEL = 10; # I'm deep The reason for this hardly limiting limitation is simple: efficiency. new my $address = Email::Address->new(undef, 'casey@local'); my $address = Email::Address->new('Casey West', 'casey@local'); my $address = Email::Address->new(undef, 'casey@local', '(Casey)'); Constructs and returns a new "Email::Address" object. Takes four positional arguments: phrase, email, and comment, and original string. The original string should only really be set using "parse". purge_cache Email::Address->purge_cache; One way this module stays fast is with internal caches. Caches live in memory and there is the remote possibility that you will have a memory problem. In the off chance that you think you're one of those people, this class method will empty those caches. I've loaded over 12000 objects and not encountered a memory problem. Instance Methods phrase my $phrase = $address->phrase; $address->phrase( "Me oh my" ); Accessor and mutator for the phrase portion of an address. address my $addr = $address->address; $addr->address( "me@PROTECTED.com" ); Accessor and mutator for the address portion of an address. comment my $comment = $address->comment; $address->comment( "(Work address)" ); Accessor and mutator for the comment portion of an address. original my $orig = $address->original; Accessor for the original address found when parsing, or passed to "new". host my $host = $address->host; Accessor for the host portion of an address's address. user my $user = $address->user; Accessor for the user portion of an address's address. format my $printable = $address->format; Returns a properly formatted RFC 2822 address representing the object. name my $name = $address->name; This method tries very hard to determine the name belonging to the address. First the "phrase" is checked. If that doesn't work out the "comment" is looked into. If that still doesn't work out, the "user" portion of the "address" is returned. This method does not try to massage any name it identifies and instead leaves that up to someone else. Who is it to decide if someone wants their name capitalized, or if they're Irish? Overloaded Operators stringify print "I have your email address, $address."; Objects stringify to "format" by default. It's possible that you don't like that idea. Okay, then, you can change it by modifying $Email:Address::STRINGIFY. Please consider modifying this package variable using "local". You might step on someone else's toes if you don't. { local $Email::Address::STRINGIFY = 'address'; print "I have your address, $address."; # geeknest.com } print "I have your address, $address."; # "Casey West" Did I Mention Fast? On my 877Mhz 12" Apple Powerbook I can run the distributed benchmarks and get results like this. $ perl -Ilib bench/ea-vs-ma.pl bench/corpus.txt 5 s/iter Mail::Address Email::Address Mail::Address 1.59 -- -31% Email::Address 1.10 45% -- $ perl -Ilib bench/ea-vs-ma.pl bench/corpus.txt 25 s/iter Mail::Address Email::Address Mail::Address 1.58 -- -60% Email::Address 0.630 151% -- $ perl -Ilib bench/ea-vs-ma.pl bench/corpus.txt 50 s/iter Mail::Address Email::Address Mail::Address 1.58 -- -65% Email::Address 0.558 182% -- SEE ALSO Email::Simple, perl.
