# Mail::Body

# Body

The body is where the text of the email is stored. Mail treats the body as a single object. The body itself has no information about boundaries used in the MIME standard, it just looks at it's content as either a single block of text, or (if it is a multipart message) as an array of blocks o text.

A body has to be told to split itself up into a multipart message by calling split with the correct boundary. This is because the body object has no way of knowing what the correct boundary is for itself (there could be many boundaries in a body in the case of a nested MIME text).

Once split is called, Mail::Body will slice itself up on this boundary, assigning anything that appears before the first part to the preamble, and anything that appears after the closing boundary to the epilogue, then each part gets initialized into a Mail::Part object.

The boundary that is used to split up the Body is also stored in the Body object for use on encoding itself back out to a string. You can overwrite this if it needs to be changed.

On encoding, the body will return the preamble, then each part joined by the boundary, followed by a closing boundary string and then the epilogue.

      if @parts
        @parts << val
      else
        @parts = Mail::PartsList.new[val]
      end
    end

==(other) click to toggle source

Matches this body with another body. Also matches the decoded value of this body with a string.

Examples:

    body = Mail::Body.new('The body')
    body == body #=> true

    body = Mail::Body.new('The body')
    body == 'The body' #=> true

    body = Mail::Body.new("VGhlIGJvZHk=\n")
    body.encoding = 'base64'
    body == "The body" #=> true

    # File lib/mail/body.rb, line 65
    def ==(other)
      if other.class == String
        self.decoded == other
      else
        super
      end
    end

=~(regexp) click to toggle source

Accepts a string and performs a regular expression against the decoded text

Examples:

    body = Mail::Body.new('The body')
    body =~ /The/ #=> 0

    body = Mail::Body.new("VGhlIGJvZHk=\n")
    body.encoding = 'base64'
    body =~ /The/ #=> 0

    # File lib/mail/body.rb, line 83
    def =~(regexp)
      self.decoded =~ regexp
    end

boundary() click to toggle source

Returns the boundary used by the body

    # File lib/mail/body.rb, line 236
    def boundary
      @boundary
    end

boundary=( val ) click to toggle source

Allows you to change the boundary of this Body object

    # File lib/mail/body.rb, line 241
    def boundary=( val )
      @boundary = val
    end

charset() click to toggle source

    # File lib/mail/body.rb, line 186
    def charset
      @charset
    end

charset=( val ) click to toggle source

    # File lib/mail/body.rb, line 190
    def charset=( val )
      @charset = val
    end

decoded() click to toggle source

    # File lib/mail/body.rb, line 174
    def decoded
      if !Encodings.defined?(encoding)
        raise UnknownEncodingType, "Don't know how to decode #{encoding}, please call #encoded and decode it yourself."

      end
    end

empty?() click to toggle source

    # File lib/mail/body.rb, line 272
    def empty?
      !!raw_source.to_s.empty?
    end

encoded(transfer_encoding = '8bit') click to toggle source

Returns a body encoded using transfer_encoding. Multipart always uses an identiy encoding (i.e. no encoding). Calling this directly is not a good idea, but supported for compatibility TODO: Validate that preamble and epilogue are valid for requested encoding

    # File lib/mail/body.rb, line 149
    def encoded(transfer_encoding = '8bit')
      if multipart?
        self.sort_parts!
        encoded_parts = parts.map { |p| p.encoded }
        ([preamble] + encoded_parts).join(crlf_boundary) + end_boundary + epilogue.to_s
      else
        be = get_best_encoding(transfer_encoding)
        dec = Mail::Encodings::get_encoding(encoding)
        enc = Mail::Encodings::get_encoding(be)
        if transfer_encoding == encoding and dec.nil?
            # Cannot decode, so skip normalization
            raw_source
        else
            # Decode then encode to normalize and allow transforming
            # from base64 to Q-P and vice versa
            decoded = dec.decode(raw_source)
            if defined?(Encoding) && charset && charset != "US-ASCII"
              decoded.encode!(charset)
              decoded.force_encoding('BINARY') unless Encoding.find(charset).ascii_compatible?
            end
            enc.encode(decoded)
        end
      end
    end

encoding(val = nil) click to toggle source

    # File lib/mail/body.rb, line 194
    def encoding(val = nil)

      end
    end

encoding=( val ) click to toggle source

    # File lib/mail/body.rb, line 202

      else
          val
      end
    end

Sets the epilogue to a string (adds text after the last MIME boundary)

    # File lib/mail/body.rb, line 226
    def epilogue=( val )
      @epilogue = val
    end

get_best_encoding(target) click to toggle source

    # File lib/mail/body.rb, line 140
    def get_best_encoding(target)
      target_encoding = Mail::Encodings.get_encoding(target)
      target_encoding.get_best_compatible(encoding, raw_source)
    end

include?(other) click to toggle source

Accepts anything that responds to to_s and checks if it's a substring of the decoded text

    end

sort_parts!() click to toggle source

Allows you to sort the parts according to the default sort order, or the sort order you set with :set_sort_order.

sort_parts! is also called from :encode, so there is no need for you to call this explicitly

    # File lib/mail/body.rb, line 126
    def sort_parts!
      @parts.each do |p|
        p.body.set_sort_order(@part_sort_order)
        @parts.sort!(@part_sort_order)
        p.body.sort_parts!
      end
    end

      self.preamble = parts[0].to_s.strip
      # Make the epilogue equal to the epilogue (if any)
      self.epilogue = parts[-1].to_s.sub('--', '').strip
