Today I finally got around to making
mailto: links and the Send Link command in
IceWeasel work with Gnus and Emacs the way I want.
Now when I click on a
mailto: link or select Send Link, I'm prompted in my
running Emacs session for a Gnus posting style, and a new message is started
with the headers and body populated according to that style and any parameters
in the link.
There are three steps to doing this.
First, put this function in your
(defun johnsu01/mailto (url)
"Follow a mailto URL as passed from Iceweasel, prompting for a posting style."
(completing-read "Use posting style of group: "
(setq url (url-unhex-string url))
;; message-mail does not do anything with the body argument, so we have to.
(if (string-match (regexp-quote "?") url)
(let* ((start (match-end 0))
(substring url start nil)))
(body (cadr (assoc-string "body" args t))))
(switch-to-buffer (car (message-buffers)))
I suspect that for the posting styles to work properly (along with other Gnus
goodness), you want to have this in your
~/.gnus if you don't already:
(setq mail-user-agent 'gnus-user-agent)
Second, write a tiny shell script to launch
emacsclient with the needed
arguments, and make it executable. This is what I use:
# $Id: mailto.sh,v 1.5 2007/02/04 07:03:32 johnsu01 Exp $
/usr/bin/emacsclient -e "(johnsu01/mailto \"$1\")"
Third, configure IceWeasel to use this script to handle
mailto: links. Browse
about:config. Search for "mailto:", to see if the parameter
network.protocol-handler.app.mailto is already defined. If it's not there
already, create it by right-clicking to New/String. The value should be the
path to your shell script. So, mine is
mailto: links should now be working (assuming you have a running Emacs server).
I was off on a wild goose chase for a while writing my own function to do what
browse-url-mail does, and then I was experimenting with
url-mailto, but I think in the end this way is the best. I'm not sure what's
going on with the body parameter (which is used when you click Send Link, to
mail a URL to someone). Things would be much simpler if it were handled
properly, but it's not. The body is passed as a an argument to the message
composition command, but none of the commands that fill that role that I
checked do anything with it. That's not surprising, given this note in
;; FIXME: message-mail should do something if YANK-ACTION is not
Well, when there is a body, YANK-ACTION is
insert-buffer. I thought
for a bit about what the right way to fix this would be, but I shelved it and
went with the the homegrown function above.
(I've since been pointed to
gnus-url-mailto, which does seem to do the right
thing with the body, but doesn't give me the posting styles option and doesn't
leave point where I would like.)
