-
- What is tm-edit?
- ****************
-
- *tm-edit* is a general MIME composer for GNU Emacs.
-
- tm-edit is based on mime.el by UMEDA Masanobu
- <umerin@mse.kyutech.ac.jp>, who is famous as the author of GNUS.
- tm-edit expands following points from `mime.el':
-
- * based on RFC 1521/1522
-
- * Content-Disposition field (*Note (tm-en)Content-Disposition::)
- (RFC 1806) supports
-
- * nested multi-part message (*Note (tm-en)multipart::)
-
- * PGP (*Note PGP::) (PGP/MIME (RFC 2015) based on security multipart
- (RFC 1847) and application/pgp based on traditional PGP)
-
- * strength automatic specification for parameter of file type
-
- In tm-MUA (*Note (tm-en)tm-MUA::), you can edit MIME message easily
- to use tm-edit.
-
- File: tm-edit-en.info, Node: mime/editor-mode, Next: single-part operations, Prev: Introduction, Up: Top
-
- mime/editor-mode
- ****************
-
- *mime/editor-mode* is a minor mode to compose MIME message. In this
- mode, *tag* represents various kinds of data, you can edit multi part
- (*Note (tm-en)multipart::) message.
-
- There are 2 kinds of tags:
-
- * single-part tag
-
- * multi-part tag
-
- single-part tag represents single part, this form is following:
-
- --[[TYPE/SUBTYPE;PARAMETERS][ENCODING]
- OPTIONAL-FIELDS]
-
- TYPE/SUBTYPE and PARAMETERS indicates type/subtype and parameters of
- Content-Type field (*Note (tm-en)Content-Type field::). TYPE/SUBTYPE is
- required, PARAMETERS is optional.
-
- ENCODING indicates Content-Transfer-Encoding field. It is optional
- too.
-
- OPTIONAL-FIELDS is to represent another fields except Content-Type
- field and Content-Transfer-Encoding field.
-
- multi-part tags represent multi part (*Note (tm-en)multipart::).
- They consist of a pair of *multi-part beginning tag* and *multi-part
- ending tag*.
-
- multi-part beginning tag's form is following:
-
- --<<TYPE>>-{
-
- multi-part ending tag's form is following:
-
- --}-<<TYPE>>
-
- A region from multi-part beginning tag to multi-part ending tag is
- called as *enclosure*.

-
- single-part operations
- **********************
-
- Operations to make single-part are following:
-
- `<C-c C-x C-t>'
- Insert single-part tag indicates text part.
-
- `<C-c C-x C-i>'
- Insert file as a MIME attachment. If `C-u' is followed by it, it
- asks media-type, subtype or encoding even if their default values
- are specified. (cf. *Note tag specification for inserted file::)
-
- `<C-c C-x C-e>'
- Insert external part.
-
- `<C-c C-x C-v>'
- Record audio input until `C-g' is pressed, and insert as a audio
- part. (It requires /dev/audio in default.)
-
- `<C-c C-x C-y>'
- Insert current (mail or news) message. (It is MUA depended.)
-
- `<C-c C-x C-m>'
- Insert mail message. (It is MUA depended.)
-
- `<C-c C-x C-w>, <C-c C-x C-s>'
- Insert signature.
-
- `<C-c C-x C-k>'
- Insert PGP (*Note PGP::) public key. (It requires Mailcrypt
- package.)
-
- `<C-c C-x t>'
- Insert any single-part tag.
-
- File: tm-edit-en.info, Node: enclosure operation, Next: other operations of mime/editor-mode, Prev: single-part operations, Up: Top
-
- enclosure operation
- *******************
-
- Operations to make enclosure are following:
-
- `<C-c C-x a>'
- Enclose specified region as multipart/alternative.
-
- `<C-c C-x p>'
- Enclose specified region as multipart/parallel.
-
- `<C-c C-x m>'
- Enclose specified region as multipart/mixed.
-
- `<C-c C-x d>'
- Enclose specified region as multipart/digest.
-
- `<C-c C-x s>'
- Digital-sign to specified region. (cf. *Note PGP::)
-
- `<C-c C-x e>'
- Encrypt to specified region. (cf. *Note PGP::)
-
- `<C-c C-x q>'
- avoid to encode tags in specified region. In other words, tags is
- interpreted as such string. (In current version, it may be
- incomplete. Maybe PGP-signature does not work for this enclosure.)

-
- other operations of mime/editor-mode
- ************************************
-
- There are another operations in mime/editor-mode.
-
- `<C-c C-c>'
- Send current editing message.
-
- `<C-c C-x C-p>'
- Preview current editing message. (*Note
- (tm-view-en)mime/viewer-mode::)
-
- `<C-c C-x C-z>'
- Exit mime/editor-mode. (<M-x mime/edit-again> is available to
- reedit.)
-
- `<C-c C-x ?>'
- Display help message.
-
- `<C-c C-x />'
- Set current editing message to enable automatic splitting or not.
- Form of automatic split messages is message/partial.
-
- `<C-c C-x 7>'
- Set 7bit (*Note (tm-en)7bit::) to transfer level (*Note transfer
- level::).
-
- `<C-c C-x 8>'
- Set 8bit (*Note (tm-en)8bit::) to transfer level (*Note transfer
- level::).
-
- `<C-c C-x v>'
- Set current editing message to digital-sign or not. (cf. *Note
- PGP::)
-
- `<C-c C-x h>'
- Set current editing message to encrypt or not. (cf. *Note PGP::)

-
- Default media-type or encoding for inserted file
- ************************************************
-
- When `C-c C-x C-i' (`mime-editor/insert-file') is pressed, tag
- parameters for inserted file, such as media-type or encoding, are
- detected by variable `mime-file-types'.
-
- When `C-u' is followed by it or parameter is not found from the
- variable, it asks from user. (When `C-u' is followed by it, detected
- value is used as default value)
-
- If you want to change default value for file names, please change
- variable `mime-file-types'.
-
- - Variable: mime-file-types
- Specification of default value of tag for file name of inserted
- file.
-
- It is a list of following list:
-
- (FILE_PAT TYPE SUBTYPE PARAMS ENCODING
- DISPOSITION_TYPE DISPOSITION_PARAMS)
-
- Each elements of the list are following:
-
- `FILE_PAT'
- regular expression of file name
-
- `TYPE'
- media type
-
- `SUBTYPE'
- media subtype
-
- `PARAMS'
- parameters of Content-Type field
-
- `ENCODING'
- Content-Transfer-Encoding
-
- `DISPOSITION_TYPE'
- disposition-type
-
- `DISPOSITION_PARAMS'
- parameters of Content-Disposition field
-
- Example: Specify application/rtf as default media type for `*.rtf'
-
- (call-after-loaded
- 'tm-edit
- (lambda ()
- (set-alist 'mime-file-types
- "\\.rtf$"
- '("application" "rtf" nil nil
- "attachment" (("filename" . file)))
- )))

-
- transfer level
- **************
-
- Contents inserted in a message are represented by 7bit (*Note
- (tm-en)7bit::), 8bit (*Note (tm-en)8bit::) or binary (*Note
- (tm-en)binary::).
-
- If a message is translated by 7bit-through MTA (*Note (tm-en)MTA::),
- there is no need to encode 7bit data, but 8bit and binary data must be
- encoded to 7bit data.
-
- Similarly, if a message is translated by 8bit-through MTA, there is
- no need to encode 7bit or 8bit data, but binary data must be encoded to
- 7bit or 8bit data.
-
- *[Memo]*
- EBCDIC MTA breaks 7bit data, so in this case, 7bit data must be
- encoded by base64. But I don't know EBCDIC. (^_^;
-
- Similarly, I wish ASCII-printable only MTA and code-conversion MTA
- disappeared. (^_^;
-
- Maybe there are binary-through MTA, but I think it is not major.
-
- *transfer level* represents how range data is available. tm-edit
- has a variable `mime-editor/transfer-level' to represent transfer level.
-
- - Variable: mime-editor/transfer-level
- transfer level.
-
- If transfer level of a data is over it, a data is encoded to 7bit.
-
- Currently, 7 or 8 is available. Default value is 7.
-
- In extension plan, EBCDIC will be 5, ASCII printable only will be
- 6, binary will be 9. But it will not be implemented.
-
- *[Memo]*
- transfer level is only for body, not for header (*Note header::).
- RFC 1521 extends RFC 822 (*Note (tm-en)RFC 822::) to use 8bit data
- in body, but it requires to use us-ascii (*Note (tm-en)us-ascii::)
- in header.
-
- File: tm-edit-en.info, Node: header, Next: PGP, Prev: transfer level, Up: Top
-
- Using non-ASCII characters in header
- ************************************
-
- RFC 1522 (*Note (tm-en)RFC 1522::) defines representation of
- non-ASCII characters in header.
-
- It is a format called as *encoded-word* (*Note
- (tm-en)encoded-word::), it is available to represent every non-ASCII
- characters by 7bit (*Note (tm-en)7bit::) to declare MIME charset (*Note
- (tm-en)MIME charset::).
-
- * Menu:
-
- * evil setting in header:: If you can not allow encoded-word
- * API about header:: Functions and variables about header
-
- File: tm-edit-en.info, Node: evil setting in header, Next: API about header, Prev: header, Up: header
-
- If you can not allow encoded-word
- =================================
-
- It is wrong to use "raw" non-ASCII characters in header not to use
- encoded-word. Because there are various kinds of coded character set
- (*Note (tm-en)Coded character set::) in the Internet, so we can not
- distinguish them if MIME charset (*Note (tm-en)MIME charset::) is not
- declared.
-
- For example, we can not distinguish iso-8859-1 (*Note
- (tm-en)iso-8859-1::) and iso-8859-2 (*Note (tm-en)iso-8859-2::) if MIME
- charset is not declared.
-
- However you can not permit to use encoded-word, please set to
- following variables:
-
- - Variable: mime/field-encoding-method-alist
- Association-list to specify field encoding method. Its key is
- field-name, value is encoding method.
-
- field-name allows string or `t' meaning any fields.
-
- Encoding method allows following: `nil' means no-conversion,
- `mime' means to convert as encoded-word, symbol represent MIME
- charset means to convert as the coded character set instead of to
- convert as encoded-word.
-
- field-name is searched from string. If it is not found, `t' is
- used.
-
- Default value of `mime/field-encoding-method-alist' is following:
-
- (("X-Nsubject" . iso-2022-jp-2)
- ("Newsgroups" . nil)
- (t . mime)
- ))
-
- In addition, if you want to specify by coded character set instead of
- field, please use `mime-eword/charset-encoding-alist'. (cf. *Note API
- about header::)
-
- File: tm-edit-en.info, Node: API about header, Prev: evil setting in header, Up: header
-
- Functions and variables about header
- ====================================
-
- - Command: mime/encode-message-header &optional CODE-CONVERSION
- It translate non-ASCII characters in message header of current
- buffer into network representation, such as encoded-words.
-
- If CODE-CONVERSION is non-`nil', field not encoded by encoded-word
- is converted by `mime/field-encoding-method-alist'.
-
- - Function: mime/encode-field STRING
- It encodes STRING into encoded-words as a field.
-
- Long lines are folded.
-
- - Function: mime-eword/encode-string STRING &optional COLUMN MODE
- It encodes STRING into encoded-words.
-
- Long lines are folded.
-
- COLUMN specifies start column. If it is omitted, 0 is used.
-
- MODE specifies where STRING is in. Available values are `text',
- `comment', `phrase'. If it is omitted, `phrase' is used.
-
- - Variable: mime-eword/charset-encoding-alist
- Association-list of symbol represent MIME charset vs. nil, `"B"' or
- `"Q"'.
-
- `nil' means not to encode as encoded-word. `"B"' means to use
- B-encoding. `"Q"' means to use Q-encoding.
