File: rmailmm.el.html

Essentially based on the design of Alexander Pohoyda's MIME extensions (mime-display.el and mime.el).

This file provides two operation modes for viewing a MIME message.

(1) When rmail-enable-mime is non-nil (now it is the default), the
function rmail-show-mime is automatically called. That function shows a MIME message directly in RMAIL's view buffer.

(2) When rmail-enable-mime is nil, the command 'v' (or M-x
rmail-mime) shows a MIME message in a new buffer "*RMAIL*".

Both operations share the intermediate functions rmail-mime-process and rmail-mime-process-multipart as below.

rmail-show-mime
  +- rmail-mime-parse
  | +- rmail-mime-process <--+------------+
  | | +---------+ |
  | + rmail-mime-process-multipart --+
  |
  + rmail-mime-insert <----------------+
      +- rmail-mime-insert-text |
      +- rmail-mime-insert-bulk |
      +- rmail-mime-insert-multipart --+

rmail-mime
 +- rmail-mime-show <----------------------------------+
      +- rmail-mime-process |
           +- rmail-mime-handle |
                +- rmail-mime-text-handler |
                +- rmail-mime-bulk-handler |
                | + rmail-mime-insert-bulk
                +- rmail-mime-multipart-handler |
                     +- rmail-mime-process-multipart --+

In addition, for the case of rmail-enable-mime being non-nil, this file provides two functions rmail-insert-mime-forwarded-message and rmail-insert-mime-resent-message for composing forwarded and resent messages respectively.

Todo:

Make rmail-mime-media-type-handlers-alist usable in the first operation mode. Handle multipart/alternative in the second operation mode. Offer the option to call external/internal viewers (doc-view, xpdf, etc).
