Emacs. +<p> +tm-view provides the major-mode called <a +node="mime/viewer-mode"><code>mime/viewer-mode</code> </a> to read +MIME message for MUA. <a file="tm-en" node="MUA">MUA</a> implementer +can use it to add MIME function. +<p> +tm-view is a user interface kernel to view and navigate MIME message. +tm-view drives some programs to navigate each <dref +file="tm-en">content-type</dref>s, they are called <a +node="method"><concept>method</concept></a>. tm-view calls some +programs to display each contents and headers in preview buffer, they +are called <a node="Two buffers for an +article"><concept>filter</concept></a>. Method and filters are +tm-view application program. They expand tm-view to treat various +kinds of MIME types. + + +<h1> Structure of display in mime/viewer-mode +<node> MIME display +<p> +In <a node="mime/viewer-mode">mime/viewer-mode</a>, following are +displayed for each parts: +<p> +<verb> + [content-button] + (content-header) + + (content-body) + (content-separator) +</verb> +<p> +You can change design or stop to display if you specify for each +conditions, such as content-types. +<p> +Example: + +<verb> +From: morioka@jaist.ac.jp (MORIOKA Tomohiko) +Subject: Re: Question +Newsgroups: zxr.message.mime +Date: 22 Oct 93 11:02:44 +Mime-Version: 1.0 +Organization: Japan Advanced Institute of Science and Technology, + Ishikawa, Japan + +[1 (text/plain)] + 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. + +[2 (image/gif)] + +[3 (text/plain)] + + In this way, it is finish a message attaching a picture. + +======================== A cup of Russian tea ======================== +============ * not by jam, not by marmalade, by honey * ============ +============ MORIOKA Tomohiko ============ +=============== Internet E-mail: <morioka@jaist.ac.jp> =============== +</verb> + + +<h2> content-button +<node> content-button +<p> +content-subject displays abstract for the part.

And kind of decoding operations are called +<concept>decoding-mode</concept>. +<p> +When decoding operation is driven, tm-view calls a procedure matched +for the condition, such as <dref file="tm-en">content-type</dref> of +the part or its environment. This procedure is called +<concept>method</concept>. +<p> +There are two kinds of methods. One is Emacs Lisp function, called +<concept>internal method</concept>. Another one is external program, +called <concept>external method</concept>. +<p> +Internal method operates in Emacs, so it can do carefully. +<p> +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. + + +<h2> Setting decoding condition for parts +<node> decoding-condition +<p> +When decoding operation is driven, tm-view calls a method matched for +the condition searched from the variable +<code>mime/content-decoding-condition</code>. +<p> +Variable <code>mime/content-decoding-condition</code> is defined as a +list with the following syntax: +<p> +<lisp> + (condition_1 condition_2 ...) +</lisp> +<p> +Each condition are association-list with the following syntax: +<p> +<lisp> + ((field-type_1 . value_1) + (field-type_2 . value_2) + ...) +</lisp> +<p> +For example, if you want to call the external method named tm-plain to +decode every <dref file="tm-en">text/plain</dref> type parts, you can +define the condition like: +<p> +<lisp> + ((type . "text/plain") + (method "tm-plain" nil 'file 'type 'encoding 'mode 'name)) +</lisp> +<p> +This condition definition will match all parts whose <dref +file="tm-en">content-type</dref> are text/plain.

Emacs. +<p> +tm-view provides the major-mode called <a +node="mime/viewer-mode"><code>mime/viewer-mode</code> </a> to read +MIME message for MUA. <a file="tm-en" node="MUA">MUA</a> implementer +can use it to add MIME function. +<p> +tm-view is a user interface kernel to view and navigate MIME message. +tm-view drives some programs to navigate each <dref +file="tm-en">content-type</dref>s, they are called <a +node="method"><concept>method</concept></a>. tm-view calls some +programs to display each contents and headers in preview buffer, they +are called <a node="Two buffers for an +article"><concept>filter</concept></a>. Method and filters are +tm-view application program. They expand tm-view to treat various +kinds of MIME types. + + +<h1> Structure of display in mime/viewer-mode +<node> MIME display +<p> +In <a node="mime/viewer-mode">mime/viewer-mode</a>, following are +displayed for each parts: +<p> +<verb> + [content-button] + (content-header) + + (content-body) + (content-separator) +</verb> +<p> +You can change design or stop to display if you specify for each +conditions, such as content-types. +<p> +Example: + +<verb> +From: morioka@jaist.ac.jp (MORIOKA Tomohiko) +Subject: Re: Question +Newsgroups: zxr.message.mime +Date: 22 Oct 93 11:02:44 +Mime-Version: 1.0 +Organization: Japan Advanced Institute of Science and Technology, + Ishikawa, Japan + +[1 (text/plain)] + 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. + +[2 (image/gif)] + +[3 (text/plain)] + + In this way, it is finish a message attaching a picture. + +======================== A cup of Russian tea ======================== +============ * not by jam, not by marmalade, by honey * ============ +============ MORIOKA Tomohiko ============ +=============== Internet E-mail: <morioka@jaist.ac.jp> =============== +</verb> + + +<h2> content-button +<node> content-button +<p> +content-subject displays abstract for the part.

And kind of decoding operations are called +<concept>decoding-mode</concept>. +<p> +When decoding operation is driven, tm-view calls a procedure matched +for the condition, such as <dref file="tm-en">content-type</dref> of +the part or its environment. This procedure is called +<concept>method</concept>. +<p> +There are two kinds of methods. One is Emacs Lisp function, called +<concept>internal method</concept>. Another one is external program, +called <concept>external method</concept>. +<p> +Internal method operates in Emacs, so it can do carefully. +<p> +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. + + +<h2> Setting decoding condition for parts +<node> decoding-condition +<p> +When decoding operation is driven, tm-view calls a method matched for +the condition searched from the variable +<code>mime/content-decoding-condition</code>. +<p> +Variable <code>mime/content-decoding-condition</code> is defined as a +list with the following syntax: +<p> +<lisp> + (condition_1 condition_2 ...) +</lisp> +<p> +Each condition are association-list with the following syntax: +<p> +<lisp> + ((field-type_1 . value_1) + (field-type_2 . value_2) + ...) +</lisp> +<p> +For example, if you want to call the external method named tm-plain to +decode every <dref file="tm-en">text/plain</dref> type parts, you can +define the condition like: +<p> +<lisp> + ((type . "text/plain") + (method "tm-plain" nil 'file 'type 'encoding 'mode 'name)) +</lisp> +<p> +This condition definition will match all parts whose <dref +file="tm-en">content-type</dref> are text/plain.
