# Bundler::URI::MailTo

RFC6068, the mailto URL scheme.

### Constants

COMPONENT

  An Array of the available components for `Bundler::URI::MailTo`.

DEFAULT_PORT

  A Default port of nil for `Bundler::URI::MailTo`.

### Attributes

headers[R]

E-mail headers set by the URL, as an Array of Arrays.

to[R]

The primary e-mail address of the URL, as a String.

### Public Class Methods

build(args) click to toggle source

## Description¶ ↑

Creates a new `Bundler::URI::MailTo` object from components, with syntax checking.

Components can be provided as an Array or Hash. If an Array is used, the components must be supplied as `[to, headers]`.

If a Hash is used, the keys are the component names preceded by colons.

The headers can be supplied as a pre-encoded string, such as `"subject=subscribe&cc=address"`, or as an Array of Arrays like `[['subject', 'subscribe'], ['cc', 'address']]`.

Examples:

    require 'bundler/vendor/uri/lib/uri'

    m1 = Bundler::URI::MailTo.build(['joe@example.com', 'subject=Ruby'])
    m1.to_s  # => "mailto:joe@example.com?subject=Ruby"

    m2 = Bundler::URI::MailTo.build(['john@example.com', [['Subject', 'Ruby'], ['Cc', 'jack@example.com']]])
    m2.to_s  # => "mailto:john@example.com?Subject=Ruby&Cc=jack@example.com"

    m3 = Bundler::URI::MailTo.build({:to => 'listman@example.com', :headers => [['subject', 'subscribe']]})
    m3.to_s  # => "mailto:listman@example.com?subject=subscribe"

                   # File bundler/vendor/uri/lib/uri/mailto.rb, line 86
    def self.build(args)
      tmp = Util.make_components_hash(self, args)

      case tmp[:to]
      when Array
        tmp[:opaque] = tmp[:to].join(',')
      when String
        tmp[:opaque] = tmp[:to].dup
      else
        tmp[:opaque] = ''
      end

      if tmp[:headers]
        query =
          case tmp[:headers]
          when Array
            tmp[:headers].collect { |x|
              if x.kind_of?(Array)
                x[0] + '=' + x[1..-1].join
              else
                x.to_s
              end
            }.join('&')
          when Hash
            tmp[:headers].collect { |h,v|
              h + '=' + v
            }.join('&')
          else
            tmp[:headers].to_s
          end
        unless query.empty?
          tmp[:opaque] << '?' << query
        end
      end

      super(tmp)
    end

new(*arg) click to toggle source

## Description¶ ↑

Creates a new `Bundler::URI::MailTo` object from generic URL components with no syntax checking.

This method is usually called from `Bundler::URI::parse`, which checks the validity of each component.

                   # File bundler/vendor/uri/lib/uri/mailto.rb, line 133
    def initialize(*arg)
      super(*arg)

      @to = nil
      @headers = []

      # The RFC3986 parser does not normally populate opaque
      @opaque = "?#{@query}" if @query && !@opaque

      unless @opaque
        raise InvalidComponentError,
          "missing opaque part for mailto URL"
      end
      to, header = @opaque.split('?', 2)
      # allow semicolon as a addr-spec separator
      # http://support.microsoft.com/kb/820868
      unless /\A(?:[^@,;]+@[^@,;]+(?:\z|[,;]))*\z/ =~ to
        raise InvalidComponentError,
          "unrecognised opaque part for mailtoURL: #{@opaque}"
      end

      if arg[10] # arg_check
        self.to = to
        self.headers = header
      else
        set_to(to)
        set_headers(header)
      end
    end

### Public Instance Methods

Setter for headers `v`.

                   # File bundler/vendor/uri/lib/uri/mailto.rb, line 233
    def headers=(v)
      check_headers(v)

      set_to(v)
      v
    end

to_mailtext() click to toggle source

Returns the RFC822 e-mail text equivalent of the URL, as a String.

Example:

    uri = Bundler::URI.parse("mailto:ruby-list@ruby-lang.org?Subject=subscribe&cc=myaddr")
    uri.to_mailtext
    # => "To: ruby-list@ruby-lang.org\nSubject: subscribe\nCc: myaddr\n\n\n"

                   # File bundler/vendor/uri/lib/uri/mailto.rb, line 269
        def to_mailtext
          to = Bundler::URI.decode_www_form_component(@to)
          head = ''
          body = ''
          @headers.each do |x|
            case x[0]
            when 'body'
              body = Bundler::URI.decode_www_form_component(x[1])
            when 'to'
              to << ', ' + Bundler::URI.decode_www_form_component(x[1])
            else
              head << Bundler::URI.decode_www_form_component(x[0]).capitalize + ': ' +
                Bundler::URI.decode_www_form_component(x[1])  + "\n"
            end
          end

          "To: #{to}
    #{head}
    #{body}
    "
        end

Also aliased as: to_rfc822text
to_rfc822text() click to toggle source
Alias for: to_mailtext
to_s() click to toggle source

    def to_s
      @scheme + ':' +
