Reading html emails in mutt with links2

   Sometimes you get an email, which doesn't come with a plain text version,
   making it hard to read without a web browser. There are easier ways than
   the following, but they require more/different software. This method
   parses an email through links2 and displays it.

code

   Save the following as an executable. Preferably inside $PATH. I call it
   'mr', placed inside ~/bin.

 #!/bin/sh
 tmp=/tmp/muttmail.html
 cat - > $tmp
 [ "$1" = "" ] && (links -dump $tmp | less) || links -g $tmp
 :>$tmp

   Since links doesn't understand '-' redirection, this firstly cats the
   email into a temporary file 'muttmail.html'. The html extension ensures
   links knows to parse the html tags into a readable form (this can also be
   forced on any file with a -force-html flag).

   The test line checks if 'mr' is run with any arguments. If it is not, it
   dumps the email into less. Typing 'mr' with any argument - ie: 'mr g' opens
   the email in graphical links, with clickable urls and (depending on your
   links configuration) loads images. Lastly the temporary file is emptied.

in practice

   Select an email. Press v. Select the text/html file and press '|' and type
   'mr', the parsed email opens in less. Or type 'mr whatever', the email opens
   in graphical links.
