31 ;; This is an Emacs minor mode for editing Internet multimedia
32 ;; messages formatted in MIME (RFC 1521 and RFC 1522). All messages in
33 ;; this mode are composed in the tagged MIME format, that are
34 ;; described in the following examples. The messages composed in the
35 ;; tagged MIME format are automatically translated into a MIME
36 ;; compliant message when exiting the mode.
38 ;; Mule (a multilingual extension to Emacs 18 and 19) has a capability
39 ;; of handling multilingual text in limited ISO-2022 manner that is
40 ;; based on early experiences in Japanese Internet community and
41 ;; resulted in RFC 1468 (ISO-2022-JP charset for MIME). In order to
42 ;; enable multilingual capability in single text message in MIME,
43 ;; charset of multilingual text written in Mule is declared as either
44 ;; `ISO-2022-JP-2' [RFC 1554] or `ISO-2022-INT-1'. Mule is required
45 ;; 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/editor-mode automatically:
51 ;; (autoload 'mime/editor-mode "tm-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 'mime/editor-mode)
58 ;; (add-hook 'mail-send-hook 'mime-editor/maybe-translate)
60 ;; In case of MH-E, you need the following hook definition:
62 ;; (add-hook 'mh-letter-mode-hook
66 ;; (make-local-variable 'mail-header-separator)
67 ;; (setq mail-header-separator "--------")
69 ;; (add-hook 'mh-before-send-letter-hook 'mime-editor/maybe-translate)
71 ;; In case of News mode, you need the following hook definition:
73 ;; (add-hook 'news-reply-mode-hook 'mime/editor-mode)
74 ;; (add-hook 'news-inews-hook 'mime-editor/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/editor-mode-hook
83 ;; (setq font-lock-keywords (list mime-editor/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.

648 In this mode, basically, the message is composed in the tagged MIME
649 format. The message tag looks like:
651 `--[[text/plain; charset=ISO-2022-JP][7bit]]'.
653 The tag specifies the MIME content type, subtype, optional parameters
654 and transfer encoding of the message following the tag. Messages
655 without any tag are treated as `text/plain' by default. Charset and
656 transfer encoding are automatically defined unless explicitly
657 specified. Binary messages such as audio and image are usually hidden.
658 The messages in the tagged MIME format are automatically translated
659 into a MIME compliant message when exiting this mode.
661 Available charsets depend on Emacs version being used. The following
662 lists the available charsets of each emacs.
664 EMACS 18: US-ASCII is only available.
665 NEmacs: US-ASCII and ISO-2022-JP are available.
666 EMACS 19: US-ASCII and ISO-8859-1 (or other charset) are available.
667 XEmacs 19: US-ASCII and ISO-8859-1 (or other charset) are available.
668 Mule: US-ASCII, ISO-8859-* (except for ISO-8859-5), KOI8-R,
669 ISO-2022-JP, ISO-2022-JP-2, ISO-2022-KR, BIG5 and
670 ISO-2022-INT-1 are available.
672 ISO-2022-JP-2 and ISO-2022-INT-1 charsets used in mule is expected to
673 be used to represent multilingual text in intermixed manner. Any
674 languages that has no registered charset are represented as either
675 ISO-2022-JP-2 or ISO-2022-INT-1 in mule.
677 If you want to use non-ISO-8859-1 charset in EMACS 19 or XEmacs 19,
678 please set variable `default-mime-charset'. This variable must be
679 symbol of which name is a MIME charset.
681 If you want to add more charsets in mule, please set variable
682 `charsets-mime-charset-alist'. This variable must be alist of which
683 key is list of leading-char/charset and value is symbol of MIME
684 charset. (leading-char is a term of MULE 1.* and 2.*. charset is a
685 term of XEmacs/mule, mule merged EMACS and MULE 3.*) If name of
686 coding-system is different as MIME charset, please set variable
687 `mime-charset-coding-system-alist'. This variable must be alist of
688 which key is MIME charset and value is coding-system.
