Subject: Contextual tag auto-exclusion
Date: Sun, 18 Oct 2009 23:48:22 -0400	[thread overview]
Message-ID: <34D54B2A-D7AD-4534-B95A-7C1C9EA7FBAF@gmail.com> (raw)

I've submitted a feature today which provide contextual auto-exclusion  
for tags in the Agenda view.  For example, I use the following tags  
for TODOs:

   Net      Needs internet access
   Call     Needs a phone
   Errand   Done in town
   Home     Done at home

Now, it's quite easy for my computer to figure out which of these are  
possible, based on my location:

   Net      Can I ping mail.gnu.org?
   Call     Am I outside of normal calling hours?
   Errand   Am I outside of business hours?
   Home     Does my IP address begin with 192.168.9?

With the patch I've submitted, I can now define this function to auto- 
exclude based on this type of context information:

(defun org-my-auto-exclude-function (tag)
   (and (cond
	((string= tag "Net")
	 (/= 0 (call-process "/sbin/ping" nil nil nil
			     "-c1" "-q" "-t1" "mail.gnu.org")))
	((string= tag "Home")
	 (with-temp-buffer
	   (call-process "/sbin/ifconfig" nil t nil "en0" "inet")
	   (goto-char (point-min))
	   (not (re-search-forward "inet 192\\.168\\.9\\." nil t))))
	((or (string= tag "Errand") (string= tag "Call"))
	 (let ((hour (nth 2 (decode-time))))
	   (or (< hour 8) (> hour 21)))))
        (concat "-" tag)))

All I have to do is type `/ RET' in the agenda view now, and it  
excludes based on my machine's current temporal and physical context.

This feature will be described in the manual under the section  
"Commands in the agenda buffer".
