Overview

Class Address

Provides a complete handling library for email addresses. Can parse a string of an address directly or take in preformatted addresses themselves. Allows you to add and remove phrases from the front of the address and provides a compare function for email addresses.

Parsing and Handling a Valid Address:

Just pass the email address in as a string to Address.parse:

email = TMail::Address.parse('Mikel Lindsaar <[email protected]>')
#=> #<TMail::Address [email protected]>
email.address
#=> "[email protected]"
email.local
#=> "mikel"
email.domain
#=> "lindsaar.net"
email.name             # Aliased as phrase as well
#=> "Mikel Lindsaar"

Detecting an Invalid Address

If you want to check the syntactical validity of an email address, just pass it to Address.parse and catch any SyntaxError:

begin
  TMail::Address.parse("mikel   2@@@@@ me .com")
rescue TMail::SyntaxError
  puts("Invalid Email Address Detected")
else
  puts("Address is valid")
end
#=> "Invalid Email Address Detected"

Constructor Details

#initialize(local, domain) ⇒ Address

Address.new(local, domain)

Accepts:

  • local - Left of the at symbol

  • domain - Array of the domain split at the periods.

For example:

Address.new("mikel", ["lindsaar", "net"])
#=> "#<TMail::Address [email protected]>"

  if local && (local.join == '@' || local.join =~ /\A[^"].*?@.*?[^"]\Z/)

Class Method Details

.parse(str) ⇒ Object

Sometimes you need to parse an address, TMail can do it for you and provide you with a fairly robust method of detecting a valid address.

Takes in a string, returns a TMail::Address object.

Raises a TMail::SyntaxError on invalid email format

def Address.parse( str )
  Parser.parse :ADDRESS, str
end

Instance Method Details

#==(other) ⇒ Object Also known as: eql?

Provides == function to the email. Only checks the actual address and ignores the name/phrase component

For Example

addr1 = TMail::Address.parse("My Address <[email protected]>")
#=> "#<TMail::Address [email protected]>"
addr2 = TMail::Address.parse("Another <[email protected]>")
#=> "#<TMail::Address [email protected]>"
addr1 == addr2
#=> true

def ==( other )

  obj.routes.replace @routes
  obj
end

#hash ⇒ Object

#routes ⇒ Object Also known as: route

This is still here from RFC 822, and is now obsolete per RFC2822 Section 4.

“When interpreting addresses, the route portion SHOULD be ignored.”

It is still here, so you can access it.

Routes return the route portion at the front of the email address, if any.

For Example:

email = TMail::Address.parse( "<@sa,@another:[email protected]>")
=> #<TMail::Address [email protected]>
email.to_s
=> "<@sa,@another:[email protected]>"
email.routes
=> ["sa", "another"]
