Hello,

I recently switched in-buffer completion from company [1] to
completion-at-point with corfu [2] as the UI.

As I wanted email address completion via completion-at-point in
message-mode too, I implemented a new EUDC function to go into
completion-at-point-functions [3].

[1] https://company-mode.github.io
[2] https://github.com/minad/corfu
[3] https://github.com/emacs-mirror/emacs/blob/master/lisp/net/eudc-capf.el

To close the loop, I also wrote an EUDC back-end to get candidates from
notmuch-address (which attached).

Now, with a eudc-server-hotlist value of

(("localhost" . notmuch-address)
 ("localhost" . macos-contacts))

and eudc-capf-complete among completion-at-point-functions in
message-mode, I get combined email address completion candidates from
both sources offered by completion-at-point when composing a new email.

Life can be a breeze at times... ;-)

I hope anyone else finds this useful.


Hoping to have helped, and looking forward to your thoughts,

  --alexander

I will have to leave to others to test this, since I'm personally still
running emacs 27 (and that is likely to continue for a while, at least
on some machines).

Is this something that you think should be included with notmuch? If so,
is it testable without requiring any extra packages?

Hello David,

thanks for your comments and questions.

You could do

     (require 'eudcb-notmuch-address)
     (eudc-notmuch-address-set-server "localhost")

and bind the function eudc-expand-inline to a key chord of your choice
in message-mode-map.

Then you'd no longer have to tweak message-completion-alist.

This assumes that eudc-expand-inline is present in Emacs 27, of course,
which I admittedly haven't checked.

What you'd probably lose (or no longer need, whichever way you view it)
is any company-mode integration.

Good question. From my point of view: why not?

Its added value would be "separation of concerns", i.e. you could drop
any company-mode integration (and resort to whatever UI
completion-at-point uses), you could stop modifying
message-completion-alist, and notmuch-address-command could stay set to
'internal in all configurations.

BUT, using the full potential depends on some core Emacs infrastructure,
which will not be released until Emacs 29.

Thus, from your point of view, it could be a two step process.

In the first step, you could describe in the documentation how to bind
eudc-expand-inline in message-mode-map, and how to set notmuch-address
as the eudc-server. Just as I described above for your Emacs 27 setup.
This would allow you to refrain from modifying message-completion-alist,
and you could also drop any company mode integration from
notmuch-address.el

In the second step, when Emacs 29 will be released, the need for using
eudc-expan-inline will be removed, and adding notmuch-address as an EUDC
server alone will be enough.

> If so, is it testable without requiring any extra packages?

The short answer is yes.

On an Emacs prior to version 29, there will be two restrictions: there
won't be any way of having EUDC contribute to completion-at-point, and
there won't be any multi-server query support in EUDC either. That said,
you can still use it in a less versatile way as I have described above
for your Emacs 27 setup.

On an Emacs 29 or better, both gaps are filled (EUDC multi-server query,
and completion-at-point), and message.el is updated to give the EUDC
completion-at-point function a "foot in the door", i.e. it will be
called _before_ message-completion-function when completion-at-point is
invoked. Thus, if you add notmuch-address to eudc-server-hotlist,
completion candidates from normuch-address will automagically show up
without any further tweaking of message-mode on your part.


Many thanks and looking forward to your thoughts,

  --alexander
