Can I get match count?

Can I get match count?

[Osamu OKANO]

Hi.

I' like to know a count of search results.
(message
 "You have %s habits which are out of date."
 (org-agenda-match-count
  (tags-todo "STYLE=\"habit\"+SCHEDULED<=\"<now>\"")))
Is there any way?

Regards.

You could use org-map-entries to count the number of occurrences:

(length 
 (org-map-entries t "STYLE=\"habit\"+SCHEDULED<=\"<now>\"" 'agenda))

Best,

Hi!
Thank you for your advice.
I made a growl script and set to crontab.
It works correctly.

#+BEGIN_SRC sh
m=`emacsclient -e '(org-agenda-match-count
"TODO=\"TODO\"STYLE=\"habit\"+SCHEDULED<=\"<now>\"")'`
if [ "0" -ne $m ]
then
    growlnotify \
        /t:"org habit" \
        /s:true \
        /silent:true \
        "$m habits left."
fi
#+END_SRC

#+BEGIN_SRC emacs-lisp
(defun org-agenda-match-count (str)
 (length
  (org-map-entries t str 'agenda)))
#+END_SRC

Regards.
