Outdated egg!
This is an egg for CHICKEN 4, the unsupported old release. You're almost certainly looking for the CHICKEN 5 version of this egg, if it exists.
If it does not exist, there may be equivalent functionality provided by another egg; have a look at the egg index. Otherwise, please consider porting this egg to the current version of CHICKEN.

Description
email-address provides eMail address handling procedures for reading eMail addresses in RFC 822 format as well as reading lists of addresses, such as commonly found in a 'To:' header.

Requirements
API
Parsers
email-address
- email-address string-port-or-lazy-sequenceprocedure
This API will take its argument and try to parse a single mailbox or group. If nothing parses or there are characters left over after the parsing completes then the parse fails and #f is returned.
email-address-list
- email-address-list string-port-or-lazy-sequenceprocedure
This API will take its argument and try to parse a list of addresses separated by commas or whitespace.
It will parse as many addresses (mailboxes or groups) as it can. Any unparsable data will be returned in the 2nd value. If everything was parsable then the 2nd value will be #<lazy-null>.
This parser is much more lenient than a To: header parser because it allows the addresses to be delimited with whitespace and it does not require the whole input to be parsable in order to succeed.
Serialisers
name->string
- name->string email-addressprocedure
Returns the name part of the address
> (use email-address) > (name->string (email-address "Andy Bennett <andyjpb@example.net>")) "Andy Bennett"
local-part->string
- local-part->string email-addressprocedure
Returns the local part of the address as it appears in the original: the RFC allows MTAs to be case sensitive.
> (use email-address) > (local-part->string (email-address "Andy Bennett <ANDYJPB@EXAMPLE.NET>")) "ANDYJPB"
local-part->string-ci
- local-part->string-ci email-addressprocedure
Returns a lower case version of the local part of the address. Use this if you know that the MTAs for the relevant domain are not case-sensitive. You can also use this to deduplicate addresses with mixed case local parts for domains with MTAs that are not case-sensitive.
> (use email-address) > (local-part->string-ci (email-address "Andy Bennett <ANDYJPB@EXAMPLE.NET>")) "andyjpb"
domain-part->string
- domain-part->string email-addressprocedure
Returns a lower case version of the domain part of the address: DNS domain names are always case insensitive.
> (use email-address) > (domain-part->string (email-address "Andy Bennett <ANDYJPB@EXAMPLE.NET>")) "example.net"
addr-spec->string
- addr-spec->string email-addressprocedure
Returns the local@domain part of the email-address, suitable for use in an SMTP dialogue. The case of the local part will be the same in the original address. The domain part will be lower case.
> (use email-address) > (addr-spec->string (email-address "Andy Bennett <ANDYJPB@EXAMPLE.NET>")) "ANDYJPB@example.net"
Examples
RFC 822 Mailboxes
(use email-address) (email-address "andyjpb@example.net") (email-address "Andy Bennett <andyjpb@example.net>") (email-address "Andy Bennett <@home,@computer:andyjpb@example.net>") (email-address "Andy (the egg author) Bennett <andy.bennett@example.net>") ; This one contains a comment that will not appear in the parsed output. (email-address "\"Andy Bennett (Chicken)\" <andyjpb@example.net>")
RFC 822 Groups
(use email-address) (email-address "Chicken Peeps: andyjpb@example.net;") (email-address "Chicken Peeps: Andy Bennett <andyjpb@example.net>, andy.bennett@example.net;")
