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 (a multilingual extension to Emacs 18 and 19) has a capability
40 ;; of handling multilingual text in limited ISO-2022 manner that is
41 ;; based on early experiences in Japanese Internet community and
42 ;; resulted in RFC 1468 (ISO-2022-JP charset for MIME). In order to
43 ;; enable multilingual capability in single text message in MIME,
44 ;; charset of multilingual text written in Mule is declared as either
45 ;; `ISO-2022-JP-2' [RFC 1554]. Mule is required for reading the such
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 'mime-edit-mode "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 'mime-edit-mode)
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
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 'mime-edit-mode)
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.

695 In this mode, basically, the message is composed in the tagged MIME
696 format. The message tag looks like:
698 --[[text/plain; charset=ISO-2022-JP][7bit]]
700 The tag specifies the MIME content type, subtype, optional parameters
701 and transfer encoding of the message following the tag. Messages
702 without any tag are treated as `text/plain' by default. Charset and
703 transfer encoding are automatically defined unless explicitly
704 specified. Binary messages such as audio and image are usually hidden.
705 The messages in the tagged MIME format are automatically translated
706 into a MIME compliant message when exiting this mode.
708 Available charsets depend on Emacs version being used. The following
709 lists the available charsets of each emacs.
711 EMACS 18: US-ASCII is only available.
712 NEmacs: US-ASCII and ISO-2022-JP are available.
713 EMACS 19: US-ASCII and ISO-8859-1 (or other charset) are available.
714 XEmacs 19: US-ASCII and ISO-8859-1 (or other charset) are available.
715 Mule: US-ASCII, ISO-8859-* (except for ISO-8859-5), KOI8-R,
716 ISO-2022-JP, ISO-2022-JP-2, ISO-2022-KR, BIG5 and
717 ISO-2022-INT-1 are available.
719 ISO-2022-JP-2 and ISO-2022-INT-1 charsets used in mule is expected to
720 be used to represent multilingual text in intermixed manner. Any
721 languages that has no registered charset are represented as either
722 ISO-2022-JP-2 or ISO-2022-INT-1 in mule.
724 If you want to use non-ISO-8859-1 charset in EMACS 19 or XEmacs 19,
725 please set variable `default-mime-charset'. This variable must be
726 symbol of which name is a MIME charset.
728 If you want to add more charsets in mule, please set variable
729 `charsets-mime-charset-alist'. This variable must be alist of which
730 key is list of leading-char/charset and value is symbol of MIME
