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

875 In this mode, basically, the message is composed in the tagged MIME
876 format. The message tag looks like:
878 --[[text/plain; charset=ISO-2022-JP][7bit]]
880 The tag specifies the MIME content type, subtype, optional parameters
881 and transfer encoding of the message following the tag. Messages
882 without any tag are treated as `text/plain' by default. Charset and
883 transfer encoding are automatically defined unless explicitly
884 specified. Binary messages such as audio and image are usually
885 hidden. The messages in the tagged MIME format are automatically
886 translated into a MIME compliant message when exiting this mode.
888 Available charsets depend on Emacs version being used. The following
889 lists the available charsets of each emacs.
891 Without mule: US-ASCII and ISO-8859-1 (or other charset) are available.
892 With mule: US-ASCII, ISO-8859-* (except for ISO-8859-5), KOI8-R,
893 ISO-2022-JP, ISO-2022-JP-2, EUC-KR, CN-GB-2312,
894 CN-BIG5 and ISO-2022-INT-1 are available.
896 ISO-2022-JP-2 and ISO-2022-INT-1 charsets used in mule is expected to
897 be used to represent multilingual text in intermixed manner. Any
898 languages that has no registered charset are represented as either
899 ISO-2022-JP-2 or ISO-2022-INT-1 in mule.
901 If you want to use non-ISO-8859-1 charset in Emacs 19 or XEmacs
902 without mule, please set variable `default-mime-charset'. This
903 variable must be symbol of which name is a MIME charset.
905 If you want to add more charsets in mule, please set variable
906 `charsets-mime-charset-alist'. This variable must be alist of which
907 key is list of charset and value is symbol of MIME charset. If name
908 of coding-system is different as MIME charset, please set variable
909 `mime-charset-coding-system-alist'. This variable must be alist of
910 which key is MIME charset and value is coding-system.
912 Following commands are available in addition to major mode commands:
915 \\[mime-edit-insert-text] insert a text message.
