Instance Attribute Details

#port ⇒ Object (readonly)

Provides access to the port this email is using to hold it’s data

Example:

mail = TMail::Mail.parse(email_string)
mail.port
#=> #<TMail::StringPort:id=0xa2c952>

# File 'lib/action_mailer/vendor/tmail-1.2.3/tmail/obsolete.rb', line 123

def Mail.boundary
  ::TMail.new_boundary
end

.load(fname) ⇒ Object Also known as: load_from, loadfrom

Opens an email that has been saved out as a file by itself.

This function will read a file non-destructively and then parse the contents and return a TMail::Mail object.

Does not handle multiple email mailboxes (like a unix mbox) for that use the TMail::UNIXMbox class.

Example:

mail = TMail::Mail.load('filename')

# File 'lib/action_mailer/vendor/tmail-1.2.3/tmail/mail.rb', line 98

# File 'lib/action_mailer/vendor/tmail-1.2.3/tmail/obsolete.rb', line 127

def Mail.msgid
  ::TMail.new_message_id
end

.parse(str) ⇒ Object

Parses an email from the supplied string and returns a TMail::Mail object.

Example:

require 'rubygems'; require 'tmail'
email_string =<<HEREDOC
To: [email protected]
From: [email protected]
Subject: This is a short Email

Hello there Mikel!

HEREDOC
mail = TMail::Mail.parse(email_string)
#=> #<TMail::Mail port=#<TMail::StringPort:id=0xa30ac0> bodyport=nil>
mail.body
#=> "Hello there Mikel!\n\n"

def parse( str )
  new(StringPort.new(str))
end

Instance Method Details

#[](key) ⇒ Object Also known as: fetch

Returns a TMail::AddressHeader object of the field you are querying. Examples:

@mail['from']  #=> #<TMail::AddressHeader "[email protected]">
@mail['to']    #=> #<TMail::AddressHeader "[email protected]">

You can get the string value of this by passing “to_s” to the query: Example:

@mail['to'].to_s #=> "[email protected]"



247
248
249
 
# File 'lib/action_mailer/vendor/tmail-1.2.3/tmail/mail.rb', line 247

def []( key )
  @header[key.downcase]
end

#[]=(key, val) ⇒ Object Also known as: store

Allows you to set or delete TMail header objects at will. Examples:

@mail = TMail::Mail.new
@mail['to'].to_s       # => '[email protected]'
@mail['to'] = '[email protected]'
@mail['to'].to_s       # => '[email protected]'
@mail.encoded          # => "To: [email protected]\r\n\r\n"
@mail['to'] = nil
@mail['to'].to_s       # => nil
@mail.encoded          # => "\r\n"

Note: setting mail[] = nil actually deletes the header field in question from the object, it does not just set the value of the hash to nil

end

#bcc=(*strs) ⇒ Object

Destructively sets the “Bcc:” field to the passed array of strings (which should be valid email addresses)

Example:

mail = TMail::Mail.new
mail.bcc = ["[email protected]", "Mikel <[email protected]>"]

#bcc_addrs(default = nil) ⇒ Object

Return a TMail::Addresses instance for each entry in the “Bcc:” field of the mail object header.

If the “Bcc:” field does not exist, will return nil by default or the value you pass as the optional parameter.

Example:

    h.addrs
  else
    default
  end
end

#bcc_addrs=(arg) ⇒ Object

Destructively set the to field of the “Bcc:” header to equal the passed in string.

TMail will parse your contents and turn each valid email address into a TMail::Address object before assigning it to the mail message.

Example:

mail = TMail::Mail.new
mail.bcc = "Mikel <[email protected]>, another Mikel <[email protected]>"
mail.bcc_addrs #=>  [#<TMail::Address [email protected]>, #<TMail::Address [email protected]>]

  # Usage:

#cc(default = nil) ⇒ Object

Returns who the email cc’d as an Array of email addresses as opposed to an Array of TMail::Address objects which is what Mail#to_addrs returns

#cc=(*strs) ⇒ Object

Destructively sets the “Cc:” field to the passed array of strings (which should be valid email addresses)

Example:

mail = TMail::Mail.new
mail.cc = ["[email protected]", "Mikel <[email protected]>"]
mail.cc #=>  ["[email protected]", "[email protected]"]
mail['cc'].to_s #=> "[email protected], Mikel <[email protected]>"

#cc_addrs(default = nil) ⇒ Object

Return a TMail::Addresses instance for each entry in the “Cc:” field of the mail object header.

If the “Cc:” field does not exist, will return nil by default or the value you pass as the optional parameter.

Example:

mail = TMail::Mail.new
mail.cc_addrs #=> nil
mail.cc_addrs([]) #=> []
mail.cc = "Mikel <[email protected]>, another Mikel <[email protected]>"

  end
end

#cc_addrs=(arg) ⇒ Object

Destructively set the to field of the “Cc:” header to equal the passed in string.

TMail will parse your contents and turn each valid email address into a TMail::Address object before assigning it to the mail message.

Example:

mail = TMail::Mail.new

end

#charset(default = nil) ⇒ Object

Returns the character set of the email. Returns nil if no encoding set or returns whatever default you pass as a parameter - note passing the parameter does NOT change the mail object in any way.

Example:

mail = TMail::Mail.load("path_to/utf8_email")
mail.charset #=> "UTF-8"

mail = TMail::Mail.new
mail.charset #=> nil
mail.charset("US-ASCII") #=> "US-ASCII"

def charset( default = nil )
  if h = @header['content-type']
    h['charset'] or default
  else
    default
  end
end

#charset=(str) ⇒ Object

Destructively sets the character set used by this mail object to the passed string, you should note though that this does nothing to the mail body, just changes the header value, you will need to transliterate the body as well to match whatever you put in this header value if you are changing character sets.

Example:

mail = TMail::Mail.new
mail.charset #=> nil
mail.charset = "UTF-8"
mail.charset #=> "UTF-8"

end

#content_type(default = nil) ⇒ Object

Returns the current “Content-Type” of the mail instance.

If the content_type field does not exist, returns nil by default or you can pass in as the parameter for what you want the default value to be.

Example:

mail = TMail::Mail.new
mail.content_type #=> nil
mail.content_type([]) #=> []
mail = TMail::Mail.load("../test/fixtures/raw_email")
mail.content_type #=> "text/plain"
