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

835 "MIME minor mode for editing the tagged MIME message.
837 In this mode, basically, the message is composed in the tagged MIME
838 format. The message tag looks like:
840 --[[text/plain; charset=ISO-2022-JP][7bit]]
842 The tag specifies the MIME content type, subtype, optional parameters
843 and transfer encoding of the message following the tag. Messages
844 without any tag are treated as `text/plain' by default. Charset and
845 transfer encoding are automatically defined unless explicitly
846 specified. Binary messages such as audio and image are usually
847 hidden. The messages in the tagged MIME format are automatically
848 translated into a MIME compliant message when exiting this mode.
850 Available charsets depend on Emacs version being used. The following
851 lists the available charsets of each emacs.
853 Without mule: US-ASCII and ISO-8859-1 (or other charset) are available.
854 With mule: US-ASCII, ISO-8859-* (except for ISO-8859-5), KOI8-R,
855 ISO-2022-JP, ISO-2022-JP-2, EUC-KR, CN-GB-2312,
856 CN-BIG5 and ISO-2022-INT-1 are available.
858 ISO-2022-JP-2 and ISO-2022-INT-1 charsets used in mule is expected to
859 be used to represent multilingual text in intermixed manner. Any
860 languages that has no registered charset are represented as either
861 ISO-2022-JP-2 or ISO-2022-INT-1 in mule.
863 If you want to use non-ISO-8859-1 charset in Emacs 19 or XEmacs
864 without mule, please set variable `default-mime-charset'. This
865 variable must be symbol of which name is a MIME charset.
867 If you want to add more charsets in mule, please set variable
868 `charsets-mime-charset-alist'. This variable must be alist of which
869 key is list of charset and value is symbol of MIME charset. If name
870 of coding-system is different as MIME charset, please set variable
871 `mime-charset-coding-system-alist'. This variable must be alist of
872 which key is MIME charset and value is coding-system.

914 The following is a message example written in the tagged MIME format.
915 TABs at the beginning of the line are not a part of the message:
917 This is a conventional plain text. It should be translated
920 This is also a plain text. But, it is explicitly specified as
