What is tm-view?
****************

The tm-view is a general MIME viewer running on GNU Emacs.

   tm-view provides the major-mode called `mime/viewer-mode' (*Note
mime/viewer-mode::) to read MIME message for MUA.  MUA (*Note
(tm-en)MUA::) implementer can use it to add MIME function.

   tm-view is a user interface kernel to view and navigate MIME message.
tm-view drives some programs to navigate each content-type (*Note
(tm-en)content-type::)s, they are called *method* (*Note method::).
tm-view calls some programs to display each contents and headers in
preview buffer, they are called *filter* (*Note Two buffers for an
article::).  Method and filters are tm-view application program.  They
expand tm-view to treat various kinds of MIME types.

Structure of display in mime/viewer-mode
****************************************

In mime/viewer-mode (*Note mime/viewer-mode::), following are displayed
for each parts:

     	[content-button]
     	(content-header)
     
     	(content-body)
     	(content-separator)

   You can change design or stop to display if you specify for each
conditions, such as content-types.

   Example:

       How to compose MIME message in MIME-Edit mode.
     
       Press `C-c C-x ?' then help message will be displayed:
     
     C-c C-x C-t	insert a text message.
     C-c C-x TAB	insert a (binary) file.
     C-c C-x C-e	insert a reference to external body.
     C-c C-x C-v	insert a voice message.
     C-c C-x C-y	insert a mail or news message.
     C-c C-x RET	insert a mail message.
     C-c C-x C-s	insert a signature file at end.
     C-c C-x t	insert a new MIME tag.
     C-c C-x a	enclose as multipart/alternative.
     C-c C-x p	enclose as multipart/parallel.
     C-c C-x m	enclose as multipart/mixed.
     C-c C-x d	enclose as multipart/digest.
     C-c C-x s	enclose as PGP signed.
     C-c C-x e	enclose as PGP encrypted.
     C-c C-x C-k	insert PGP public key.
     C-c C-x C-p	preview editing MIME message.
     ...
     
     So press `C-c C-x C-i' and specify file name you want to include.
     
       MIME encoding for binary file is normally Base64.

* content-body::
* content-separator::


File: tm-view-en.info,  Node: content-button,  Next: content-header,  Prev: MIME display,  Up: MIME display

content-button
==============

content-subject displays abstract for the part.  It is placed in top of
the part.

   In default, it is displayed following design:

             [1.3 test (text/plain)]

   First number field represents position of a content in the part.  It
is called *content-number*.  It can be considered as the chapter number
in the message.

   Second string part represents title.  It is created by following:

  1. name paramater or x-name parameter in Content-Type field (*Note
     (tm-en)Content-Type field::)

  2. Content-Description field (*Note (tm-en)Content-Description
     field::) or Subject field

  3.  filename of uuencode

   If they are not exists, space is displayed.

   Third parenthesis part represents content-type/subtype of the part.
If it is non-MIME part, `nil' is displayed.

   Content-button is used like icon when content-header (*Note
content-header::) and content-body (*Note content-body::) are hidden.
For example:

             [2  (image/gif)]

if you press `v' key, GIF image is displayed.

   If mouse operations are available, you can press content-button by
mouse button-2 (center button of 3 button-mouse) to play, similarly to
press `v' key. (cf. *Note mime/viewer-mode::)

   By the way, it is annoying to display content-button if
content-header is displayed.  So tm-view provides a mechanism to
specify conditions to display content-button.

 - Variable: mime-viewer/content-button-ignored-ctype-list
     List of content-types.

     If content-type of a part is a member of this list, its
     content-button is not displayed.


File: tm-view-en.info,  Node: content-header,  Next: content-body,  Prev: content-button,  Up: MIME display

content-header
==============

A content header displays the header portion of a part in the
preview-buffer.  However it is annoying to display header for every
parts, so tm-view provides a mechanism to specify its condition.

   When the function `mime-viewer/header-visible-p' returns `t' for
reversed-content-number of a part, content-header is displayed.

   This judge function returns `t' when a part is root or content-type
of its parent is a member of the variable
`mime-viewer/childrens-header-showing-Content-Type-list'.

   If you want to change this condition, please redefine it.  Notice
that it refers variable
`mime-viewer/childrens-header-showing-Content-Type-list', however if
you redefine function `mime-viewer/header-visible-p', it may not work.
So if you want to redefine it, it should be refer variable
`mime-viewer/childrens-header-showing-Content-Type-list'.

   When content-header is displayed, content-header are formated by the
program called by *content-header-filter*.  Content-header-filter is
searched from variable `mime-viewer/content-header-filter-alist'.  Its
key is major-mode of the raw-article-buffer (*Note
raw-article-buffer::).  If not found, function
`mime-viewer/default-content-header-filter' is called.

 - Variable: mime-viewer/childrens-header-showing-Content-Type-list
     List of content-types.  If content-type of parent of a part is a
     member of this variable, its content-header is displayed.  Default
     value is `'("message/rfc822" "message/news")'.

     This variable is referred by the function
     `mime-viewer/header-visible-p'.

 - Function: mime-viewer/header-visible-p rcnum cinfo &optional ctype
     Returns `t' if a part which reversed-content-number is RCNUM in
     content-info CINFO is displayed.

     If you know content-type, you can specify by CTYPE.

 - Variable: mime-viewer/content-header-filter-alist
     Association-list whose key is major-mode of a raw-article-buffer,
     value is content-header-filter.

 - Function: mime-viewer/default-content-header-filter
     It is called when content-header-filter is not found in variable
     `mime-viewer/content-header-filter-alist'.

     It refers `mime-viewer/ignored-field-regexp'.

 - Variable: mime-viewer/ignored-field-list
     List of regular expression to represent invisible fields even if
     content-header is displayed.

     Variable `mime-viewer/ignored-field-regexp' is created from it.

     Please use function `tm:add-fields' or `tm:delete-fields' to set
     it.


File: tm-view-en.info,  Node: content-body,  Next: content-separator,  Prev: content-header,  Up: MIME display

content-body
============

*content-body* represents content of the part.

   tm-view does not display raw content body.  For example, if a content
has binary, it is hidden.  If a content has text/enriched, it is
formated.  Namely content body is hidden or formated.

   Function `mime-viewer/body-visible-p' is a judge function whether
content-body of a content is displayed.  If it returns `nil',
content-body is hidden.  In default, it returns non-`nil' when
content-type of a part is a member of variable
`mime-viewer/default-showing-Content-Type-list'.

   When content-body of a content is displayed, content-body is
formated by *content-filter*.  Content-filter is searched from variable
`mime-viewer/content-filter-alist'.  At this time, major-mode of the
raw-article-buffer (*Note raw-article-buffer::) is used as the key.

   If it is not found, function `mime-viewer/default-content-filter' is
called.

 - Variable: mime-viewer/default-showing-Content-Type-list
     List of content-type.  If content-type of a part is a member of
     this variable, its body is displayed.

 - Function: mime-viewer/body-visible-p rcnum cinfo &optional ctype
     Return non-`nil', if content-type of a part is displayed.  RCNUM
     is reversed-content-number of a part.  CINFO is content-info of
     the message.  If you know content-type of a part, you can specify
     it as argument CTYPE.

 - Variable: mime-viewer/content-filter-alist
     Association-list whose key is major-mode of a raw-article-buffer,
     value is content-filter.

 - Function: mime-viewer/default-content-filter rcnum cinfo ctype
          params subj
     It is called when content-body of a part should be displayed and
     content-filter is not found in `mime-viewer/content-filter-alist'.

     In default, it does nothing.


File: tm-view-en.info,  Node: content-separator,  Prev: content-body,  Up: MIME display

content-separator
=================

*content-separator* is displayed to represent boundary of contents.

   Content-separator is displayed by function
`mime-viewer/default-content-separator'.  In default, it displays
line-break when content-header and content-body are not displayed.

   If you want to change this condition, please redefine this function.

 - Function: mime-viewer/default-content-separator rcnum cinfo ctype
          params subj
     Display content-separator.  CNUM is content-number of a content.
     CINFO is content-info of the message.  CTYPE is content-type of a
     content.  PARAMS is Content-Type field parameters of a content.
     SUBJ is subject.

     In default, it displays line-break when content-header and
     content-body are not displayed.

Navigation in mime/viewer-mode
******************************

`mime/viewer-mode' has following functions:

`<u>'
     goes to the upper content (returns to the Summary mode if the
     cursor is sitting on the top content (*1))

`<p>'
     goes to the previous content

`<M-TAB>'
     goes to the previous content

`<n>'
     goes to the next content

`<TAB>'
     goes to the next content

`<SPC>'
     scrolls up

`<M-SPC>'
     scrolls down

`<DEL>'
     scrolls down

`<RET>'
     goes to the next line

`<M-RET>'
     goes to the previous line

`<<>'
     goes to the beginning of message

`<>>'
     goes to the end of message

`<v>'
     playbacks a part (*2)

`<e>'
     extracts a file from a part (*2)

`<C-c C-p>'
     prints a part (*2)

`<f>'
     displays X-Face in the message

`<mouse-button-2>'
     drives mouse button in preview-buffer.

     For content-button, it playbacks a part (*2)

     For URL-button, it drives WWW browser


*[Notice]*

     (*1) Not return to the Summary mode unless tm-view has been setup
     using tm-mh-e, tm-vm, gnus-mime, tm-gnus, tm-rmail etc.

     (*2) Actual playback/extract/print will be performed by a method.

Mechanism of decoding
*********************

In `mime/viewer-mode', you can do play (`v'), extract (`e'), or print
(`C-c C-p') for each parts.  These operations are called *decoding
operation(s) (for a part)*.  And kind of decoding operations are called
*decoding-mode*.

   When decoding operation is driven, tm-view calls a procedure matched
for the condition, such as content-type (*Note (tm-en)content-type::)
of the part or its environment.  This procedure is called *method*.

   There are two kinds of methods.  One is Emacs Lisp function, called
*internal method*.  Another one is external program, called *external
method*.

   Internal method operates in Emacs, so it can do carefully.

   External method is called as asynchronous process, so Emacs does not
wait while method is running.  So it is good for big data, such as
audio, image or video.

* environment variables::       Environment variables

Setting decoding condition for parts
====================================

When decoding operation is driven, tm-view calls a method matched for
the condition searched from the variable
`mime/content-decoding-condition'.

   Variable `mime/content-decoding-condition' is defined as a list with
the following syntax:

             (condition_1 condition_2 ...)

   Each condition are association-list with the following syntax:

             ((field-type_1 . value_1)
              (field-type_2 . value_2)
              ...)

   For example, if you want to call the external method named tm-plain
to decode every text/plain (*Note (tm-en)text/plain::) type parts, you
can define the condition like:

             ((type . "text/plain")
              (method "tm-plain" nil 'file 'type 'encoding 'mode 'name))

   This condition definition will match all parts whose content-type
(*Note (tm-en)content-type::) are text/plain.  Here is an another
example:

             ((type . "text/plain")
              (method "tm-plain" nil 'file 'type 'encoding 'mode 'name)
              (mode . "play"))

   This will match the part whose type is text/plain and the mode is
play.

   Here is an another example:

             ((method "metamail" t "-m" "tm" "-x" "-d" "-z" "-e" 'file)
              (mode . "play"))

   This will match all parts which have a mode of play.

   The conditions defined in a variable
`mime/content-decoding-condition' are examined from top to bottom.  The
first matching condition becomes valid and the method specified in that
condition definition will be executed.

* method value::                Format of method value
* Example of decoding-condition::


File: tm-view-en.info,  Node: method value,  Next: Example of decoding-condition,  Prev: decoding-condition,  Up: decoding-condition

Format of method value
----------------------

You can specify the method field of the decoding-condition definition in
two different ways,

             (method . SYMBOL)

or

             (method  STRING  FLAG  arg1  arg2  ...)

can be accepted.

   When a symbol is specified in the method field, a function whose
name is SYMBOL will be called as an internal method.

   When a list is specified in the method field, it will be called as an
external method.

   The list below shows the meaning of the parameters when the external
method is specified in the method field.

`STRING'
     name of an external method

`FLAG'
     If `t', both the content-header and the content-body are passed to
     an external method.

     If `nil', only the content-body is passed to an external method.

`ARGUMENTs'
     list of arguments passed to an external method


   An argument passed to an external method can be in one of the
following formats:

`STRING'
     string itself

`'SYMBOL'
     value gotten using SYMBOL as a key from decoding-condition

`'STRING'
     value gotten using STRING as a key from decoding-condition


   `'SYMBOL' can be one of the following:

`'file'
     name of a file holding the original content

`'type'
     content-type/sub-type of Content-Type field

`'encoding'
     field body of Content-Transfer-Encoding field

`'mode'
     decoding-mode

`'name'
     name of a file created by decode operation


   `'STRING' is used to search a parameter of the Content-Type field
whose name matches with it, and pass the value of that parameter to the
external method.

Example of decoding-condition
-----------------------------

Following is an example of decoding-condition:

     (defvar mime/content-decoding-condition
       '(((type . "text/plain")
          (method "tm-plain" nil 'file 'type 'encoding 'mode 'name))
         ((type . "text/x-latex")
          (method "tm-latex" nil 'file 'type 'encoding 'mode 'name))
         ((type . "audio/basic")
          (method "tm-au"    nil 'file 'type 'encoding 'mode 'name))
         ((type . "image/gif")
          (method "tm-image" nil 'file 'type 'encoding 'mode 'name))
         ((type . "image/jpeg")
          (method "tm-image" nil 'file 'type 'encoding 'mode 'name))
         ((type . "image/tiff")
          (method "tm-image" nil 'file 'type 'encoding 'mode 'name))
         ((type . "image/x-tiff")
          (method "tm-image" nil 'file 'type 'encoding 'mode 'name))
         ((type . "image/x-xbm")
          (method "tm-image" nil 'file 'type 'encoding 'mode 'name))
         ((type . "image/x-pic")
          (method "tm-image" nil 'file 'type 'encoding 'mode 'name))
         ((type . "video/mpeg")`
          (method "tm-mpeg"  nil 'file 'type 'encoding 'mode 'name))
         ((type . "application/octet-stream")
          (method "tm-file"  nil 'file 'type 'encoding 'mode 'name))
         ((type . "message/partial")
          (method . mime/decode-message/partial-region))
         ((method "metamail" t
                  "-m" "tm" "-x" "-d" "-z" "-e" 'file)(mode . "play"))
         ))

   For example, if you want to use metamail to decode any contents,

     (setq mime/content-decoding-condition
           '(
             ((method "metamail" t "-m" "tm" "-x" "-d" "-z" "-e" 'file))
            ))

will work.

   Variable `mime/content-decoding-condition' provides you of very
flexible way to define the conditions of decoding.  It can be simple if
you only need the a few decoding methods, while it can be very
complicated if you want to use the separate decoding method for each
type/mode combination.

   Following function may be useful to set decoding-condition.  It is a
function of `tl-atype.el'.

 - Function: set-atype symbol alist
     Add condition ALIST to SYMBOL.

     *[Example]*

               (set-atype 'mime/content-decoding-condition
               	   '((type . "message/external-body")
               	     ("access-type" . "anon-ftp")
               	     (method . mime/decode-message/external-ftp)
               	     ))

Environment variables
=====================

Standard methods of tm-view reference some environment variables.  You
can specify them to customize.

TM_TMP_DIR
     Directory for temporary files or extracted files.  If it is
     omitted, `/tmp/' is used.

VIDEO_DITHER
     Dither for mpeg_play.  If it is omitted, `gray' is used.

TM_WWW_BROWSER
     WWW browser name.  If it is omitted, `netscape' is used.



File: tm-view-en.info,  Node: Two buffers for an article,  Next: API,  Prev: method,  Up: Top

raw-article-buffer and preview-buffer
*************************************

tm-view managements two buffers, one is for raw message called
*raw-article-buffer*, another one is to preview for user called
*preview-buffer*.  major-mode of raw-article-buffer is same as
major-mode for article of original MUA, major-mode of preview-buffer is
`mime/viewer-mode' (*Note mime/viewer-mode::).

   When called `mime/viewer-mode', tm-view analyzes raw-article-buffer,
and sets its result to the variable `mime::article/content-info'.

   After that, tm-view create a preview-buffer corresponded to the
raw-article-buffer.  As this time, tm-view modifies header and body of
each parts of the message by specified conditions.  Filter program for
header is called *header-filter* (*Note content-header::), filter
program for body is called *content-filter* (*Note content-body::), and
they are called *filter*.

   When preview-buffer is made, buffer local variable of preview-buffer
`mime::preview/content-list' is made to register structure of
preview-buffer.  tm-view manages message by
`mime::article/content-info' in raw-article-buffer and
`mime::preview/content-list' in preview-buffer.

*[Notice]*

     In this document, I call "content-type" as content-type/subtype of

buffer local variables of raw-article-buffer
============================================

 - Structure: mime::content-info rcnum point-min point-max type
          parameters encoding children
     structure to represent MIME content in raw-article-buffer.  It is
     called by *content-info*.

     Please use reference function `mime::content-info/SLOT-NAME' to
     reference slot of content-info.  Their argument is only
     content-info.

     Following is a list of slots of the structure:

    RCNUM
          "reversed content-number" (list)

    POINT-MIN
          beginning point of region in raw-article-buffer

    POINT-MAX
          end point of region in raw-article-buffer

    TYPE
          content-type/sub-type (string or nil)

    PARAMETERS
          parameter of Content-Type field (association list)

    ENCODING
          Content-Transfer-Encoding (string or nil)

    CHILDREN
          parts included in this part (list of content-infos)


     If a part includes other parts in its contents, such as multipart
     or message/rfc822, content-infos of other parts are included in
     CHILDREN, so content-info become a tree.

 - Variable: mime::article/content-info
     result of MIME parsing of raw-article-buffer (content-info)

 - Variable: mime::article/preview-buffer
     preview-buffer corresponded by this buffer

 - Function: mime-article/point-content-number point &optional cinfo
     In a region managed by content-info CINFO, it returns
     content-number corresponded by POINT.

     If CINFO is omitted, `mime::article/content-info' is used as
     default value.

 - Function: mime-article/rcnum-to-cinfo rcnum &optional cinfo
     In a region managed by content-info CINFO, it returns content-info
     corresponded by reversed-content-number RCNUM.

     If CINFO is omitted, `mime::article/content-info' is used as
     default value.

 - Function: mime-article/cnum-to-cinfo rcnum &optional cinfo
     In a region managed by content-info CINFO, it returns content-info
     corresponded by content-number RCNUM.

     If CINFO is omitted, `mime::article/content-info' is used as

Buffer local variables of preview-buffer
========================================

 - Variable: mime::preview/mother-buffer
     Mother buffer of this preview-buffer.

 - Structure: mime::preview-content-info point-min point-max buffer
          content-info
     structure to represent MIME content in preview-buffer.  It is
     called by *preview-content-info*.

     Please use reference function
     `mime::preview-content-info/SLOT-NAME' to reference slot of
     preview-content-info.  Their argument is only preview-content-info.

     Following is a list of slots of the structure:

    POINT-MIN
          beginning point of region in preview-buffer

    POINT-MAX
          end point of region in preview-buffer

    BUFFER
          raw-article-buffer corresponding a part

    CONTENT-INFO
          content-info corresponding a part


 - Variable: mime::preview/content-list
     List of preview-content-info to represent structure of this
     preview-buffer.

 - Variable: mime::preview/article-buffer
     raw-article-buffer corresponded by this preview-buffer.

 - Variable: mime::preview/original-major-mode
     major-mode of original buffer.

 - Variable: mime::preview/original-window-configuration
     window-configuration just before made this preview-buffer.

 - Function: mime-preview/point-pcinfo point &optional pcl
     In a region of preview-buffer managed by preview-content-info PCL,
     it returns preview-content-info corresponded by POINT.

     If CINFO is omitted, `mime::preview/content-list' is used.

Functions to decode MIME message
********************************

tm-view provides some available functions to decode and navigate MIME
message to each MUA (*Note (tm-en)MUA::)s.

   There are 2 kinds of functions, one is for MIME preview, another one
is to decode RFC 1522 encoded-word (*Note (tm-en)encoded-word::).

* Menu:

* API about MIME preview::      Function to preview MIME message
* encoded-word decoding::       encoded-word decoder


File: tm-view-en.info,  Node: API about MIME preview,  Next: encoded-word decoding,  Prev: API,  Up: API

Function to preview MIME message
================================

 - Command: mime/viewer-mode &optional mother ctl encoding ibuf obuf
          mother-keymap
     Parse IBUF as a MIME message, and create preview-buffer into OBUF
     to display to user, then enter `mime/viewer-mode' (*Note
     mime/viewer-mode::).

     If IBUF is omitted, current buffer is used.

     MOTHER is used to specify original raw-article-buffer.  It may be
     useful when a raw-article-buffer is assembled from message/partial
     messages.

     CTL is used to specify Content-Type field (*Note
     (tm-en)Content-Type field::) information.  Its format is output
     format of `mime/Content-Type'.  When CTL is specified, tm-view
     uses it instead of Content-Type field of the raw-article-buffer.

     ENCODING is used to specify field-body of
     Content-Transfer-Encoding field.  When it is specified, tm-view
     uses it instead of Content-Type field of the raw-article-buffer.

     If MOTHER-KEYMAP is specified, keymap of `mime/viewer-mode'
     includes it.

encoded-word decoder
====================

tm-view has functions to decode RFC 1522 encoded-word (*Note
(tm-en)encoded-word::).

 - Command: mime/decode-message-header
     It decodes encoded-words in message header of current buffer.

     If an encoded-word is broken or invalid, or it has non supported
     MIME charset (*Note (tm-en)MIME charset::), it is not decoded.

 - Command: mime-eword/decode-region start end &optional unfolding
          must-unfold
     It decodes encoded-words in region START to END.

     If an encoded-word is broken or invalid, or it has non supported
     MIME charset (*Note (tm-en)MIME charset::), it is not decoded.

     If UNFOLDING is non-nil, it unfolds folded fields.

     If MUST-FOLD is non-nil and decoded result of an encoded-word has
     folding or raw CR or LF, it unfolds or delete raw CR or LF.

 - Function: mime-eword/decode-string string &optional must-unfold
     It decodes encoded-words in STRING and returns decoded string.

     If an encoded-word is broken or invalid, or it has non supported
     MIME charset (*Note (tm-en)MIME charset::), it is not decoded.

     If STRING is folded, it unfolds STRING before decoding.

     If MUST-FOLD is non-nil and decoded result of an encoded-word has
     folding or raw CR or LF, it unfolds or delete raw CR or LF.
