Neomutt: notmuch: autocompletion of "to/cc/bcc" addresses

[anarcat]

Right now when you compose an email in Neomutt, the autocompletion command (TAB) in the To: field yields the list of aliases. Yet the Notmuch feature provides a way more powerful autocompletion system through the notmuch-address command. This is used in the Emacs notmuch client and I use it all the time, it's one of those things that make me go back to Emacs instead of switching back to mutt (along with #628).

I'm not sure how that completion works or how customizable it is, but it would seem to me like a key feature to add.

Thanks!

it seems this is already doable, by binding the query_command parameter. this worked for me:

set query_command = "notmuch-address %s"

although the output is trimmed at 25 columns for some odd reason...

by default, <Tab> runs the complete command which looks into aliases. to complete using the query_command, you need to use the ^T shortcut. to reverse the two, use this:

bind editor <Tab> complete-query
bind editor ^T complete

this means this is basically resolved. :) thanks!

If i recall correctly, you can fix that with:

set query_format="%4c %t %-70.70a %-70.70n %?e?(%e)?"

Confirmed, thanks!

I have a question regarding this issue - using notmuch address query (with minor changes) works for me when the search results contain multiple options, but the results always cut off the first address. When the search results in only one address, neomutt stays blank.

The difference can be seen when comparing the output in a shell between:

notmuch address from:<my-string>

and when using tab completion in neomutt after the To: prompt:

To: <my-string>

My neomutt config options related to notmuch are:

set query_command = "notmuch address from:%s"
bind editor <Tab> complete-query
bind editor ^T complete
set query_format="%4c %t %-70.70a %-70.70n %?e?(%e)?"

If I should open a new issue please let me know

It might be worth noting that notmuch can also query for a regex (see man 7 notmuch-search-terms):
notmuch address from:/<regex>/
This means that youre able to tab complete with only part of the recipients name if you
set query_command = "echo '' && notmuch address from:/%s/"
(applying the echo 'n-1' fix) or similar
