31 ;; This is an Emacs minor mode for editing Internet multimedia
32 ;; messages formatted in MIME (RFC 2045, 2046, 2047, 2048 and 2049).
33 ;; All messages in this mode are composed in the tagged MIME format,
34 ;; that are described in the following examples. The messages
35 ;; composed in the tagged MIME format are automatically translated
36 ;; into a MIME compliant message when exiting the mode.
38 ;; Mule (multilingual feature of Emacs 20 and multilingual extension
39 ;; for XEmacs 20) has a capability of handling multilingual text in
40 ;; limited ISO-2022 manner that is based on early experiences in
41 ;; Japanese Internet community and resulted in RFC 1468 (ISO-2022-JP
42 ;; charset for MIME). In order to enable multilingual capability in
43 ;; single text message in MIME, charset of multilingual text written
44 ;; in Mule is declared as either `ISO-2022-JP-2' [RFC 1554]. Mule is
45 ;; required for reading the such messages.
47 ;; This MIME composer can work with Mail mode, mh-e letter Mode, and
48 ;; News mode. First of all, you need the following autoload
49 ;; definition to load mime-edit-mode automatically:
51 ;; (autoload 'turn-on-mime-edit "mime-edit"
52 ;; "Minor mode for editing MIME message." t)
54 ;; In case of Mail mode (includes VM mode), you need the following
57 ;; (add-hook 'mail-mode-hook 'turn-on-mime-edit)
58 ;; (add-hook 'mail-send-hook 'mime-edit-maybe-translate)
60 ;; In case of MH-E, you need the following hook definition:
62 ;; (add-hook 'mh-letter-mode-hook
65 ;; (turn-on-mime-edit)
66 ;; (make-local-variable 'mail-header-separator)
67 ;; (setq mail-header-separator "--------")
69 ;; (add-hook 'mh-before-send-letter-hook 'mime-edit-maybe-translate)
71 ;; In case of News mode, you need the following hook definition:
73 ;; (add-hook 'news-reply-mode-hook 'turn-on-mime-edit)
74 ;; (add-hook 'news-inews-hook 'mime-edit-maybe-translate)
76 ;; In case of Emacs 19, it is possible to emphasize the message tags
77 ;; using font-lock mode as follows:
79 ;; (add-hook 'mime-edit-mode-hook
83 ;; (setq font-lock-keywords (list mime-edit-tag-regexp))
86 ;; The message tag looks like:
88 ;; --[[TYPE/SUBTYPE;PARAMETERS][ENCODING]]
90 ;; The tagged MIME message examples:
92 ;; This is a conventional plain text. It should be translated into
96 ;; This is also a plain text. But, it is explicitly specified as is.
97 ;;--[[text/plain; charset=ISO-8859-1]]
98 ;; This is also a plain text. But charset is specified as iso-8859-1.
100 ;; ¡Hola! Buenos días. ¿Cómo está usted?
101 ;;--[[text/enriched]]

774 "MIME minor mode for editing the tagged MIME message.
776 In this mode, basically, the message is composed in the tagged MIME
777 format. The message tag looks like:
779 --[[text/plain; charset=ISO-2022-JP][7bit]]
781 The tag specifies the MIME content type, subtype, optional parameters
782 and transfer encoding of the message following the tag. Messages
783 without any tag are treated as `text/plain' by default. Charset and
784 transfer encoding are automatically defined unless explicitly
785 specified. Binary messages such as audio and image are usually
786 hidden. The messages in the tagged MIME format are automatically
787 translated into a MIME compliant message when exiting this mode.
789 Available charsets depend on Emacs version being used. The following
790 lists the available charsets of each emacs.
792 Without mule: US-ASCII and ISO-8859-1 (or other charset) are available.
793 With mule: US-ASCII, ISO-8859-* (except for ISO-8859-5), KOI8-R,
794 ISO-2022-JP, ISO-2022-JP-2, EUC-KR, CN-GB-2312,
795 CN-BIG5 and ISO-2022-INT-1 are available.
797 ISO-2022-JP-2 and ISO-2022-INT-1 charsets used in mule is expected to
798 be used to represent multilingual text in intermixed manner. Any
799 languages that has no registered charset are represented as either
800 ISO-2022-JP-2 or ISO-2022-INT-1 in mule.
802 If you want to use non-ISO-8859-1 charset in Emacs 19 or XEmacs
803 without mule, please set variable `default-mime-charset'. This
804 variable must be symbol of which name is a MIME charset.
806 If you want to add more charsets in mule, please set variable
807 `charsets-mime-charset-alist'. This variable must be alist of which
808 key is list of charset and value is symbol of MIME charset. If name
809 of coding-system is different as MIME charset, please set variable
810 `mime-charset-coding-system-alist'. This variable must be alist of
811 which key is MIME charset and value is coding-system.

850 The following is a message example written in the tagged MIME format.
851 TABs at the beginning of the line are not a part of the message:
853 This is a conventional plain text. It should be translated
856 This is also a plain text. But, it is explicitly specified as
858 --[[text/plain; charset=ISO-8859-1]]
859 This is also a plain text. But charset is specified as
862 ¡Hola! Buenos días. ¿Cómo está usted?
864 This is a <bold>enriched text</bold>.
