module ActionMailer #:nodoc:
  # ActionMailer allows you to send email from your application using a mailer model and views.
  #
  # = Mailer Models
  # To use ActionMailer, you need to create a mailer model.
  #   
  #   $ script/generate mailer Notifier
  #
  # The generated model inherits from ActionMailer::Base. Emails are defined by creating methods within the model which are then 
  # used to set variables to be used in the mail template, to change options on the mail, or 
  # to add attachments.
  #
  # Examples:
  #
  #  class Notifier < ActionMailer::Base
  #    def signup_notification(recipient)
  #      recipients recipient.email_address_with_name
  #      from       "system@example.com"
  #      subject    "New account information"
  #      body       "account" => recipient
  #    end
  #  end
  #
  # Mailer methods have the following configuration methods available.
  #
  # * <tt>recipients</tt> - Takes one or more email addresses. These addresses are where your email will be delivered to. Sets the <tt>To:</tt> header.
  # * <tt>subject</tt> - The subject of your email. Sets the <tt>Subject:</tt> header.
  # * <tt>from</tt> - Who the email you are sending is from. Sets the <tt>From:</tt> header.
  # * <tt>cc</tt> - Takes one or more email addresses. These addresses will receive a carbon copy of your email. Sets the <tt>Cc:</tt> header.
  # * <tt>bcc</tt> - Takes one or more email address. These addresses will receive a blind carbon copy of your email. Sets the <tt>Bcc</tt> header.
  # * <tt>sent_on</tt> - The date on which the message was sent. If not set, the header wil be set by the delivery agent.
  # * <tt>content_type</tt> - Specify the content type of the message. Defaults to <tt>text/plain</tt>.
  # * <tt>headers</tt> - Specify additional headers to be set for the message, e.g. <tt>headers 'X-Mail-Count' => 107370</tt>.
  #
  # The <tt>body</tt> method has special behavior. It takes a hash which generates an instance variable
  # named after each key in the hash containing the value that that key points to.
  #
  # So, for example, <tt>body "account" => recipient</tt> would result
  # in an instance variable <tt>@account</tt> with the value of <tt>recipient</tt> being accessible in the 
  # view.
  #
  # = Mailer Views
  # Like ActionController, each mailer class has a corresponding view directory
  # in which each method of the class looks for a template with its name.
  # To define a template to be used with a mailing, create an <tt>.rhtml</tt> file with the same name as the method
  # in your mailer model. For example, in the mailer defined above, the template at 
  # <tt>app/views/notifier/signup_notification.rhtml</tt> would be used to generate the email.
  #
  # Variables defined in the model are accessible as instance variables in the view.
  #
  # Emails by default are sent in plain text, so a sample view for our model example might look like this:
  #
  #   Hi <%= @account.name %>,
  #   Thanks for joining our service! Please check back often.
  #
  # = Sending Mail
  # Once a mailer action and template are defined, you can deliver your message or create it and save it 
  # for delivery later:
  #
  #   Notifier.deliver_signup_notification(david) # sends the email
  #   mail = Notifier.create_signup_notification(david)  # => a tmail object
  #   Notifier.deliver(mail)
  # 
  # You never instantiate your mailer class. Rather, your delivery instance
  # methods are automatically wrapped in class methods that start with the word
  # <tt>deliver_</tt> followed by the name of the mailer method that you would
  # like to deliver. The <tt>signup_notification</tt> method defined above is
  # delivered by invoking <tt>Notifier.deliver_signup_notification</tt>.
  #
  # = HTML Email
  # To send mail as HTML, make sure your view (the <tt>.rhtml</tt> file) generates HTML and
  # set the content type to html.
  #
  #   class MyMailer < ActionMailer::Base
  #     def signup_notification(recipient)
  #       recipients recipient.email_address_with_name
  #       subject    "New account information"
  #       body       "account" => recipient
  #       from       "system@example.com"
  #       content_type "text/html"   #    Here's where the magic happens
  #     end
  #   end  
  #
  # = Multipart Email
  # You can explicitly specify multipart messages:
  #
  #   class ApplicationMailer < ActionMailer::Base
  #     def signup_notification(recipient)
  #       recipients      recipient.email_address_with_name
  #       subject         "New account information"
  #       from            "system@example.com"
  #
  #       part :content_type => "text/html",
  #         :body => render_message("signup-as-html", :account => recipient)
  #
  #       part "text/plain" do |p|
  #         p.body = render_message("signup-as-plain", :account => recipient)
  #         p.transfer_encoding = "base64"
  #       end
  #     end
  #   end
  #  
  # Multipart messages can also be used implicitly because ActionMailer will automatically
  # detect and use multipart templates, where each template is named after the name of the action, followed
  # by the content type. Each such detected template will be added as separate part to the message.
  # 
  # For example, if the following templates existed:
  # * signup_notification.text.plain.rhtml
  # * signup_notification.text.html.rhtml
  # * signup_notification.text.xml.rxml
  # * signup_notification.text.x-yaml.rhtml
  #  
  # Each would be rendered and added as a separate part to the message,
  # with the corresponding content type. The same body hash is passed to
  # each template.
  #
  # = Attachments
  # Attachments can be added by using the +attachment+ method.
  #
  # Example:
  #
  #   class ApplicationMailer < ActionMailer::Base
  #     # attachments
  #     def signup_notification(recipient)
  #       recipients      recipient.email_address_with_name
  #       subject         "New account information"
  #       from            "system@example.com"
  #
  #       attachment :content_type => "image/jpeg",
  #         :body => File.read("an-image.jpg")
  #
  #       attachment "application/pdf" do |a|
  #         a.body = generate_your_pdf_here()
  #       end
  #     end
  #   end 
  #
  # = Configuration options
  #
  # These options are specified on the class level, like <tt>ActionMailer::Base.template_root = "/my/templates"</tt>
  #
  # * <tt>template_root</tt> - template root determines the base from which template references will be made.
  #
  # * <tt>logger</tt> - the logger is used for generating information on the mailing run if available.
  #   Can be set to nil for no logging. Compatible with both Ruby's own Logger and Log4r loggers.
  #
  # * <tt>server_settings</tt> -  Allows detailed configuration of the server:
  #   * <tt>:address</tt> Allows you to use a remote mail server. Just change it from its default "localhost" setting.
  #   * <tt>:port</tt> On the off chance that your mail server doesn't run on port 25, you can change it.
  #   * <tt>:domain</tt> If you need to specify a HELO domain, you can do it here.
  #   * <tt>:user_name</tt> If your mail server requires authentication, set the username in this setting.
  #   * <tt>:password</tt> If your mail server requires authentication, set the password in this setting.
  #   * <tt>:authentication</tt> If your mail server requires authentication, you need to specify the authentication type here. 
  #     This is a symbol and one of :plain, :login, :cram_md5
  #
  # * <tt>raise_delivery_errors</tt> - whether or not errors should be raised if the email fails to be delivered.
  #
  # * <tt>delivery_method</tt> - Defines a delivery method. Possible values are :smtp (default), :sendmail, and :test.
  #   Sendmail is assumed to be present at "/usr/sbin/sendmail".
  #
  # * <tt>perform_deliveries</tt> - Determines whether deliver_* methods are actually carried out. By default they are,
  #   but this can be turned off to help functional testing.
  #
  # * <tt>deliveries</tt> - Keeps an array of all the emails sent out through the Action Mailer with delivery_method :test. Most useful
  #   for unit and functional testing.
  #
  # * <tt>default_charset</tt> - The default charset used for the body and to encode the subject. Defaults to UTF-8. You can also 
  #   pick a different charset from inside a method with <tt>@charset</tt>.
  # * <tt>default_content_type</tt> - The default content type used for the main part of the message. Defaults to "text/plain". You
  #   can also pick a different content type from inside a method with <tt>@content_type</tt>. 
  # * <tt>default_mime_version</tt> - The default mime version used for the message. Defaults to nil. You
  #   can also pick a different value from inside a method with <tt>@mime_version</tt>. When multipart messages are in
  #   use, <tt>@mime_version</tt> will be set to "1.0" if it is not set inside a method.
  # * <tt>default_implicit_parts_order</tt> - When a message is built implicitly (i.e. multiple parts are assembled from templates
  #   which specify the content type in their filenames) this variable controls how the parts are ordered. Defaults to
  #   ["text/html", "text/enriched", "text/plain"]. Items that appear first in the array have higher priority in the mail client
  #   and appear last in the mime encoded message. You can also pick a different order from inside a method with
  #   <tt>@implicit_parts_order</tt>.

# Revision History ::
# YYYY.MM.DD  Change ID   Developer
#             Description
# --------------------------------------------------------------------------
# 2002.10.18              Austin Ziegler
#             Fixed a minor problem with tabs not being counted. Changed
#             abbreviations from Hash to Array to better suit Ruby's
#             capabilities. Fixed problems with the way that Array arguments
#             are handled in calls to the major object types, excepting in
#             Text::Format#expand and Text::Format#unexpand (these will
#             probably need to be fixed).
# 2002.10.30              Austin Ziegler
#             Fixed the ordering of the <=> for binary tests. Fixed
#             Text::Format#expand and Text::Format#unexpand to handle array
#             arguments better.
# 2003.01.24              Austin Ziegler
#             Fixed a problem with Text::Format::RIGHT_FILL handling where a
#             single word is larger than #columns. Removed Comparable
#             capabilities (<=> doesn't make sense; == does). Added Symbol
#             equivalents for the Hash initialization. Hash initialization has
#             been modified so that values are set as follows (Symbols are
#             highest priority; strings are middle; defaults are lowest):
#                 @columns = arg[:columns] || arg['columns'] || @columns
#             Added #hard_margins, #split_rules, #hyphenator, and #split_words.
# 2003.02.07              Austin Ziegler
#             Fixed the installer for proper case-sensitive handling.
# 2003.03.28              Austin Ziegler
#             Added the ability for a hyphenator to receive the formatter
#             object. Fixed a bug for strings matching /\A\s*\Z/ failing
#             entirely. Fixed a test case failing under 1.6.8. 
# 2003.04.04              Austin Ziegler
#             Handle the case of hyphenators returning nil for first/rest.
# 2003.09.17          Austin Ziegler
#             Fixed a problem where #paragraphs(" ") was raising
#             NoMethodError.
