- What is gnus-mime?
- ******************
-
- *gnus-mime* is a MIME (*Note (tm-en)MIME::) extender for Gnus (*Note
- (gnus)::) using tm (*Note (tm-en)tm-kernel::).
-
- *[Notice]*
- gnus-mime is for only Gnus. Please use tm-gnus (*Note
- (tm-gnus_en)::) for GNUS.
-
- gnus-mime supports automatic MIME preview in `"*Article*"' buffer
- using tm-view (*Note (tm-view-en)::). In particular, with XEmacs, it
- decodes images as same as text.
-
- In addition, gnus-mime supports multilingual/internationalization
- feature for mule such as MULE (*Note (tm-en)mule::), XEmacs/mule and
- mule merged Emacs. It supports code-conversion by MIME charset or
- depended default MIME charset of newsgroups.
-
- For RFC 1522, original Gnus supports only Q-encoded iso-8859-1
- (*Note (tm-en)iso-8859-1::) encoded-word (*Note (tm-en)encoded-word::).
- So gnus-mime supports more MIME charsets, such as iso-8859-2 (*Note
- (tm-en)iso-8859-2::), iso-8859-3 (*Note (tm-en)iso-8859-3::), ...,
- iso-2022-jp (*Note (tm-en)iso-2022-jp::), euc-kr (*Note
- (tm-en)euc-kr::), iso-2022-kr (*Note (tm-en)iso-2022-kr::), gb2312,
- hz-gb-2312 (*Note (tm-en)hz-gb-2312::), cn-big5 (*Note
- (tm-en)cn-big5::), and B-encoding. In addition, original Gnus does not
- support unfolding or space elimination rule of RFC 1522. gnus-mime is
- more rightful.

-
- Inline display for MIME message
- *******************************
-
- *automatic MIME preview* feature is available for gnus-mime. In
- automatic MIME preview mode, when reading an article in summary mode,
- gnus-mime displays preview buffer processed by tm-view instead of raw
- article buffer. (cf. *Note (tm-view-en)::)
-
- Therefore if an article is encoded by Base64 (*Note (tm-en)Base64::)
- or Quoted-Printable (*Note (tm-en)Quoted-Printable::), a decoded
- article is displayed. Or rich text article, such as text/enriched
- (*Note (tm-en)text/enriched::) format, is automatic formated. Of
- course, multipart (*Note (tm-en)multipart::) article is dealt with
- correctly.
-
- In addition, in *XEmacs*, images are displayed in preview buffer as
- same as text.
-
- Different from using metamail, speaker does not roar just then read
- an article includes audio content, video player does not play just then
- read an article includes video content, it does not do anonymous ftp
- (*Note (tm-en)ftp::) or send mail when read an article includes
- external-message. These contents are played when you do decoding
- command in preview buffer.
-
- However if you use a slow machine, or are just really impatient, you
- can stop automatic MIME preview.

- How to process MIME in Article Buffer
- =====================================
-
- When `gnus-show-mime' is not `nil' and an article has Mime-Version
- field in its message header, namely it is a MIME message, Gnus calls
- `gnus-show-mime-method' to process MIME.
-
- When `gnus-strict-mime' is `nil' and `gnus-show-mime' is not `nil',
- Gnus calls `gnus-show-mime-method' even if an message does not have
- Mime-Version field in its message header.
-
- Gnus 5.2 or later calls `gnus-show-mime-method' when
- `gnus-strict-mime' is not `nil' and an article does not have
- Mime-Version field. Notice that old Gnus does not have it, so it may
- be better to set `gnus-strict-mime' to `nil'.
-
- - Variable: gnus-show-mime
- If it is not `nil', Gnus do automatic MIME preview. Default value
- is `t'.
-
- It is a variable of Gnus, so if gnus is loaded before gnus-mime is
- loaded, default value is not guaranteed.
-
- (cf. *Note (gnus)Using MIME::)
-
- - Variable: gnus-show-mime-method
- Gnus calls function bound by it to process MIME. Default value is
- `gnus-article-preview-mime-message'.
-
- It is a variable of Gnus, so if gnus is loaded before gnus-mime is
- loaded, default value is not guaranteed.
-
- (cf. *Note (gnus)Using MIME::)
-
- - Variable: gnus-decode-encoded-word-method
- Gnus calls function bound by it to decode encoded-words. Default
- value is `gnus-article-decode-encoded-word'.
-
- It is a variable of Gnus, so if gnus is loaded before gnus-mime is
- loaded, default value is not guaranteed.
-
- In addition, it is not available at Gnus 5.0.* or Gnus 5.1.
-
- *[Notice]*
- gnus-mime uses some variables of Gnus and defines different default
- values by `defvar'. For example, gnus-mime's default value of
- `gnus-show-mime' is `t' instead of `nil'. Or its default value of
- `gnus-show-mime-method' is `gnus-article-preview-mime-message'
- instead of `metamail-buffer'. (cf. *Note (gnus)Using MIME::)
-
- gnus-mime uses `defvar' instead of `setq', because of respect
- user's setting before gnus-mime is loaded, such as using
- `~/.emacs'. But it has a problem. If gnus is loaded before
- gnus-mime is loaded, features of gnus-mime is not available in
- default even if gnus-mime is loaded. Therefore there is serious
- problem to load gnus before gnus-mime is loaded. In other words,
- setting in `~/.gnus', such as to load `gnus-mime' or `mime-setup',
- is not good way. If you want such way, please do setting for
- `gnus-show-mime' and `gnus-show-mime-method'.

-
- Mechanism of Automatic MIME preview
- ===================================
-
- Gnus 5.2 or later has two buffers for an article,
- `gnus-original-article-buffer' (`" *Original Article*"') and
- `gnus-article-buffer' (`"*Article*"'). The former is called *raw
- article buffer*, the latter is called *preview buffer*.
-
- Content of raw article buffer is non-processed "raw message". In
- particular, for emacs variants includes mule (*Note (tm-en)mule::)
- features, message is not code-converted in it.
-
- Content of preview buffer is MIME processed message to display for
- user. In particular, for emacs variants includes mule features,
- non-ASCII message is code-converted in it by MIME charset or default
- MIME charset (*Note (tm-en)MIME charset::) for selected newsgroup.
-
- Gnus 5.0.* and Gnus 5.1 don't have distinction between raw article
- buffer and preview buffer. So gnus-mime emulate raw article buffer. It
- is unnatural, so it may be better to use Gnus 5.2 or later, which are
- designed for tm-view.
-
- (cf. *Note (tm-view-en)Two buffers for an article::)

-
- Internationalization
- ********************
-
- For emacs variants includes mule feature, such as MULE (*Note
- (tm-en)MULE::), XEmacs/mule and Emacs/mule(*1), gnus-mime supports
- code-conversion by MIME charset (*Note (tm-en)MIME charset::) or
- `default-mime-charset' of selected newsgroup.
-
- *[Memo]*
- (*1) It means next generation of Emacs includes mule features. Now
- (October 1996), HANDA Ken'ichi and RMS are developing it.
-
- Detail of code conversion is following:
-
- 1. If a newsgroup is selected, MIME charset for the newsgroup is
- searched from `gnus-newsgroup-default-charset-alist'. If it is
- found, it is set to buffer local variable `default-mime-charset'
- of Summary Buffer. If not found, global value of
- `default-mime-charset' is used.
-
- 2. Non-ASCII characters in Summary Buffer are code-converted by
- `default-mime-charset' in Summary Buffer.
-
- 3. encoded-word (*Note (tm-en)encoded-word::) are code-converted by
- their specified MIME charset (*Note (tm-en)MIME charset::).
-
- 4. Code-conversion of articles are following:
-
- 1. If a part of a MIME message has charset parameter of
- Content-Type field (*Note (tm-en)Content-Type field::), it is
- code-converted by the MIME charset.
-
- 2. When there are no specified MIME charset, such as message
- header or non-MIME message, they are code-converted by
- `default-mime-charset' in Summary Buffer.
-
- - Variable: gnus-newsgroup-default-charset-alist
- Association-list regexp for newsgroup vs. symbol for default MIME
- charset.
-
- Default setting are following:
-
- `alt.chinese.*'
- hz-gb-2312 (*Note (tm-en)hz-gb-2312::)
-
- `alt.chinese.text.big5, hk.*, hkstar.*, tw.*'
- cn-big5 (*Note (tm-en)cn-big5::)
-
- `fj.*'
- iso-2022-jp-2 (*Note (tm-en)iso-2022-jp-2::)
-
- `han.*'
- euc-kr (*Note (tm-en)euc-kr::)
-
- `relcom.*'
- koi8-r (*Note (tm-en)koi8-r::)
-
- If there is no MIME charsets for a newsgroup,
- `default-mime-charset' is used as default MIME charset.
-
- - Function: gnus-set-newsgroup-default-charsetnewsgroup CHARSET
- Set default MIME CHARSET of NEWSGROUP to
- `gnus-newsgroup-default-charset-alist'.
-
- NEWSGROUP is string of newsgroup name or category, for
- `"gnu.emacs.gnus"', `"gnu.emacs"', `"gnu"'.
-
- CHARSET is symbol of MIME charset, for example `iso-8859-1',
- `iso-2022-jp'.

-
- Composing MIME messages
- ***********************
-
- If using mime-setup (*Note (tm-en)mime-setup::), you can edit MIME
- message in message-mode using tm-edit (*Note (tm-edit-en)::).
-
- *[Notice]*
- Default setting of mime-setup avoids automatic inserting signature
- when sending a message.
-
- (cf. *Note (tm-en)mime-setup::)
-
- gnus-mime does not have implementation for `C-c C-x C-m'
- (`mime-editor/insert-mail'). Because gnus-mime does not know which
- mail-reader should be used. In addition, `C-c C-x C-y'
- (`mime-editor/insert-message') is enough to insert mail (namely to
- select a mail group and select a message to insert, then it is available
- to insert the mail message).
-
- However you can use `C-c C-x C-m' to specify an implementation of
- `message-mode' to `mime-editor/mail-inserter-alist'.
-
- Example: same as `C-c C-x C-m'
- ==============================
-
- (set-alist 'mime-editor/mail-inserter-alist
- 'message-mode (function message-mime-insert-article))
-
- Example: including from MH folder
- =================================
-
- (autoload 'tm-mh-e/insert-mail "tm-mh-e")
-
- (set-alist 'mime-editor/mail-inserter-alist
- 'message-mode (function tm-mh-e/insert-mail))
