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.

673 In this mode, basically, the message is composed in the tagged MIME
674 format. The message tag looks like:
676 --[[text/plain; charset=ISO-2022-JP][7bit]]
678 The tag specifies the MIME content type, subtype, optional parameters
679 and transfer encoding of the message following the tag. Messages
680 without any tag are treated as `text/plain' by default. Charset and
681 transfer encoding are automatically defined unless explicitly
682 specified. Binary messages such as audio and image are usually hidden.
683 The messages in the tagged MIME format are automatically translated
684 into a MIME compliant message when exiting this mode.
686 Available charsets depend on Emacs version being used. The following
687 lists the available charsets of each emacs.
689 EMACS 18: US-ASCII is only available.
690 NEmacs: US-ASCII and ISO-2022-JP are available.
691 EMACS 19: US-ASCII and ISO-8859-1 (or other charset) are available.
692 XEmacs 19: US-ASCII and ISO-8859-1 (or other charset) are available.

694 ISO-2022-JP, ISO-2022-JP-2, ISO-2022-KR, BIG5 and
695 ISO-2022-INT-1 are available.
697 ISO-2022-JP-2 and ISO-2022-INT-1 charsets used in mule is expected to
698 be used to represent multilingual text in intermixed manner. Any
699 languages that has no registered charset are represented as either
700 ISO-2022-JP-2 or ISO-2022-INT-1 in mule.
702 If you want to use non-ISO-8859-1 charset in EMACS 19 or XEmacs 19,
703 please set variable `default-mime-charset'. This variable must be
704 symbol of which name is a MIME charset.
706 If you want to add more charsets in mule, please set variable
707 `charsets-mime-charset-alist'. This variable must be alist of which
708 key is list of leading-char/charset and value is symbol of MIME
709 charset. (leading-char is a term of MULE 1.* and 2.*. charset is a
710 term of XEmacs/mule, mule merged EMACS and MULE 3.*) If name of

752 The following is a message example written in the tagged MIME format.
753 TABs at the beginning of the line are not a part of the message:
755 This is a conventional plain text. It should be translated
758 This is also a plain text. But, it is explicitly specified as
760 --[[text/plain; charset=ISO-8859-1]]
761 This is also a plain text. But charset is specified as
764 ¡Hola! Buenos días. ¿Cómo está usted?
766 This is a <bold>enriched text</bold>.
