I recently managed to set up my mailcap so that Mutt can show HTML e-mails in the message window:

# ~/.mailcap text/html; lynx -dump '%s' | more; nametemplate=%s.html; copiousoutput;

which is automated by:

# ~/.muttrc auto_view text/html

Although I think Lynx does a decent job on converting the HTML to text, sometimes this doesn't cut it and I would like to be able to open the HTML attachment in my web browser Luakit.

Is there a way to transparently do this? A good workflow for me would look like:

  1. open mail (Lynx converts it)
  2. see that it is too complicated for Lynx
  3. press v
  4. navigate to HTML attachment
  5. press Enter to open the mail in Luakit.

You can do this with mutt's mime support.

In addition, you can use this with Autoview to denote two commands for viewing an attachment, one to be viewed automatically, the other to be viewed interactively from the attachment menu.

Essentially, you include two options in your mailcap file1.

text/html; luakit '%s' &; test=test -n "$DISPLAY"; needsterminal; text/html; lynx -dump %s; nametemplate=%s.html; copiousoutput;

The first entry tests that X is running, and if it is, it hands the file to luakit. The default, however, is determined by the copiousoutput tag, so it will be rendered in Mutt by lynx.

You will need these options in your .muttrc:

auto_view text/html # view HTML automatically alternative_order text/plain text/enriched text/html # save HTML for last

If you want to look at it in your browser, it is just a matter of hitting v to view the attached HTML and then m to send it to mailcap.

For convenience, I bind Enter to that function in muttrc:

bind attach <return> view-mailcap

1. Note, I don't use lynx or luakit, so these options are indicative only.

  • If you want to avoid the needsterminal for luakit have a look a Gary Johnsons mutt-netscape script. Commented Jul 12, 2012 at 22:49

    Does it really have to read text/html; text/html; luakit ... with the text/html repeated? Commented Apr 7, 2013 at 15:54

  • @a3nm That all depends on the settings in the browser you hand off to... Commented Aug 5, 2014 at 20:42
  • @jasonwryan Yes... I'm looking for a way to invoke Firefox in a way that would disallow any external lookups. Commented Aug 5, 2014 at 20:45

Borrowing from the ArchWiki, I have this in muttrc to open HTML in my $BROWSER (Firefox, really) when pressing V in the attachment view:

# pipe-entry pipes the current entry to iconv. iconv converts text from one character encoding to another # See this for a description of Mutt functions: https://muttmua.gitlab.io/mutt/manual-dev.html#functions set my_mail=/tmp/mutt/mail.html macro attach V "<shell-escape>mkdir -p $(dirname $my_mail)<enter><pipe-entry>iconv -c --to-code=UTF8 > $my_mail<enter><shell-escape>$BROWSER $my_mail<enter>" "Open attachment with $BROWSER"
