Hi!

I was thinking about how to interface mutt and org-mode for quite some
time now but didn't really get around to it.

I've tried to use many emacs MUAs for this purpose (mh-e, wanderlust,
mew and finally the great scary GNUs) but they're not quite to my
taste.

Your proposal gave me the necessary hacktivation energy to come up
with my version of this prototype. I also borrowed some of your code,
but backported it to perl 5.8.

Those are a few steps too many for me. I wanted to press <f9>t in the
index or pager and then pop up an emacs window with remember.

As org-annotation-helper.el does this already, I decided to use it.

Also mutt is able to search its own mailboxes, not as flexible as
mairix, because it can only search a single folder, but I only really
want to link back to a certain mail for now.

I also had a long conversation with pdmef on channel #mutt on
freenode.net, who gave me the two crucial ideas how to configure this
in mutt.

The main idea is to use the path-type variable record to get the name
of the current folder and store it in the two keyboard macros. The
keyboard macros change every time you change a folder in mutt.

This is a rough prototype still. I'd like to get rid of the (y/n)
prompt and therefore I'd like to have a link-type "mutt:" in org,
which means some of the functionality of the perl-script would have to
get implemented in emacs-lisp. But that would give me the benefit of a
customisable terminal and maybe get everything a bit less hairy...

You'll notice that calling mutt with a mail is not very straight
forward. In theory,

mutt -f $mailbox -e "push <search>~i$msgid<enter><display-message>"

should be sufficient. However if it's started via xterm -e, the
keystrokes don't arrive, maybe because xterm does some terminal
initialisations after mutt has started (or my window manager sends a
resize signal a bit too late, something like that). That's why I'm
writing the keystrokes to a temporary file. Not elegant, but does the
job.

Maybe we get the next guy inspired to hack on this now :)

set my_wait_key=\$wait_key; \

END

# 2) put this file into your $HOME/bin and make it executable.

# 3) make sure org-annotation-helper.el is loaded in your org config

# 4) optionally: set $terminal above to something you prefer.

# 5) press <f9>n in the pager or index to annotate a mail url,
#    press <f9>t to *remember* it

# 6) follow the generated link in emacs to open the mail in mutt.
