Add function for getting # of unread messages about mu HOT 11 CLOSED

@djcb, do you consider revisiting this issue?

It sounds like a great improvement, even the simplest scenario "display unread counter next to a bookmark" would make user interactions with mu4e:main page way more productive.

For example, if I have 5 bookmarks, being on mu4e:main page I can easily tell that there is something new only in one of them, so I don't need to open other 4.

from mu.

From the command-line, with mu-guile installed:
$ guile -c '(use-modules (mu) (mu stats)) (mu:initialize) (format #t "~s" (mu:count "flag:unread"))'

from mu.

I think it's worth adding that to documentation.

from mu.

or a little bit shorter,
$ mu script --script=msgs-count -- --query='flag:unread'

adding something for mu4e is a 'wontfix' for now, since e..g. having it in the views would require a bit too much extra complexity.

Well there is mu4e-alert which you might consider using. Personally I didn't get on too well with it and instead hacked together a simplistic modeline notification based on some of the mu4e-alert code:

(setq kzar/mu4e-activity-string "")
(add-to-list 'global-mode-string '((:eval kzar/mu4e-activity-string)) t)
(defun kzar/get-mu4e-incoming-count ()
  (let* ((query "flag:unread AND \(maildir:/INBOX or maildir:/INBOX.Eyeo\)")
         (command (concat mu4e-mu-binary " msgs-count --query='" query "'")))
    (string-trim (shell-command-to-string command))))
(defun kzar/format-mu4e-mode-string (count)
  (concat "📧[" (if (string= count "0") "" count) "]"))
(defun kzar/update-mu4e-activity-string (&rest args)
  (setq kzar/mu4e-activity-string
        (kzar/format-mu4e-mode-string (kzar/get-mu4e-incoming-count)))
  (force-mode-line-update))
(add-hook 'mu4e-main-mode-hook #'kzar/update-mu4e-activity-string)
(add-hook 'mu4e-view-mode-hook #'kzar/update-mu4e-activity-string)
(add-hook 'mu4e-index-updated-hook #'kzar/update-mu4e-activity-string)

It doesn't update immediately after I've read an email or when I've marked one as unread. I got stuck fixing that since the database hasn't been updated at that point, so these don't work:

(advice-add #'mu4e-mark-execute-all :after #'kzar/update-mu4e-activity-string)
(advice-add #'mu4e-context-switch :after #'kzar/update-mu4e-activity-string)
(advice-add #'mu4e-headers-view-message :after #'kzar/update-mu4e-activity-string)

I would also like my C-c space hotkey that switches to active rcirc buffers to switch to my inbox view when I have incoming messages, but I've not figured out how yet.

Finally I want the incoming message count number to be highlighted when I have messages to look at, but so far haven't figured that out either!

Anyway hope it helps, Dave.

Replying a little belatedly:

• the count seems to run off the end of my modeline (see attached). Any idea how to fix that?
• do you have a way to just get the total count for messages in the current folder/view?

Thank you! Really appreciate it.

from mu.

(can't figure out how to attach, sorry!)

Reviving this... if it's possible to do something like $ mu script --script=msgs-count -- --query='flag:unread' as @djcb suggested, wouldn't it be possible to put the output of this in the view somehow?

Also - that line doesn't work anymore on 1.3.5 unfortunately. On my gentoo system I get: mu: failed to open '/usr/share/mu/scripts/': No such file or directory (73)

I'm just beginning to use mu. Running into all sorts of issues, one which lead me to this page. Is it dead?

@permezel mu is far from being dead but, if you do not describe “all sorts of issues” you encounter (in separate issues, respecting the template), it is difficult to help you.

First, you must upgrade mu:

@Chris00 Fair enough. I thought I was uptodate, but apparently not.
Am now, though:

z8% mu --version
mu (mail indexer/searcher) version 1.6.6
Copyright (C) 2008-2021 Dirk-Jan C. Binnema

Still same issues:

z8% mu zot
error: failed to open '/usr/share/mu/scripts/': No such file or directory

The rest of my issues, I will attempt to clarify.

As far as what brings me here in particular: it appears various distributions have for years not been including the /usr/share/mu/ stuff. Does this matter? Too early to tell, but I consider spurious error messages to be a sign of bit rot, which is why I inquired after the health.
