2.2 Displaying MIME

It's not difficult to read a multipart message. As usual, just type ‘SPC’.

A multipart message is marked with ‘M’ on the left side of date as follows:

 
* 03/12 Hidenori Ohta  This weekend              |Let's go to StoneMagic
 M03/14 Momo-chan      The pictures of Noto      |Attached are the pictu
  03/15 Neat Sumikawa  Re: wine                  |OK. I vote for Wednesd

When you type ‘SPC’ on the message marked with ‘M’, its header is displayed in Message mode. Then its multipart structure is displayed in Summary mode as follows:

 
* 03/12 Hidenori Ohta  This weekend              |Let's go to StoneMagic
 M03/14 Momo-chan      The pictures of Noto      |Attached are the pictu
B    2  Image/Jpeg                   picture 1                noto1.jpg
Q    3  Application/Postscript       Note map                 map.ps

If the first part is Text/, the first part is not displayed in Summary mode but the first part is displayed with its header in Message mode.

Each line of multipart consists of

Content-Description can be considered Subject: for each part. This format is very similar to that of the attachment region in Draft mode.

If you type ‘SPC’ or ‘n’, the cursor moves onto part 2 and the content is displayed according to its data type. For instance, Text/Plain is showed in Message mode and PostScript is visualized with "ghostview".

Please note that ‘n’ and ‘p’ move lines including multipart. To display the message below skipping multipart, type ‘C-un’. Likewise, to display the message above (not this message), input ‘C-up’.

Mew processes MIME recursively. The following example is a forwarded multipart message.

 
 M03/15 Kazu yamamoto  Fw: The pictures of Noto  |Attached are the pictu
     2  Message/Rfc822               The pictures of Noto
B    2.2  Image/Jpeg                   picture 1              noto1.jpg
Q    2.3  Application/Postscript       Note map               map.ps

Note: We strongly recommend that you not embed any object other than text as a top level single part to a message directly. Instead, it is better to make a multipart message whose part 1 is a textual description of part 2 and part 2 is a non-text object.

A message which contains a single part other than text is displayed as multipart.

Since the syntax of MIME messages can be complex, it sometime takes a bit of time to analyze the syntax. However, Mew guesses the message to be read next and analyzes it beforehand while the user is reading the current message. Analyzed messages are temporarily cached.

To make it clear where the message ends, Mew displays the string "[End of message]" in the end of the message. At the end of each part, Mew displays the string "[Message is continued]". These strings are customized by ‘mew-end-of-message-string’ and ‘mew-end-of-part-string’, respectively.
