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]]
102 ;; <center>This is a richtext.</center>

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

854 The following is a message example written in the tagged MIME format.
855 TABs at the beginning of the line are not a part of the message:
857 This is a conventional plain text. It should be translated
860 This is also a plain text. But, it is explicitly specified as
862 --[[text/plain; charset=ISO-8859-1]]
863 This is also a plain text. But charset is specified as
866 ¡Hola! Buenos días. ¿Cómo está usted?
868 This is a <bold>enriched text</bold>.
869 --[[image/gif][base64]]...image encoded in base64 here...
870 --[[audio/basic][base64]]...audio encoded in base64 here...
872 User customizable variables (not documented all of them):
874 Specifies a key prefix for MIME minor mode commands.
