Altering effect of deadline on priority calculation

Altering effect of deadline on priority calculation

Hi,

I would like to make deadlines have a larger impact on priority calculation
than scheduled date, but I can't figure out how to extract how many days
before or past deadline from an agenda entry.  I would also like to extract
how many days overdue a task is from its scheduled date.

Is there a function that gives me this information easily?

Alternatively, can anybody point me to where priority is increased by 1 for
each day late?

Thanks - I've looked and looked.

I'm not sure where do you want to get this information from:
from an agenda view? from a normal buffer?

What value of `org-agenda-sorting-strategy' comes closest to
what you are trying to achieve?

Let us know,

Actually, I have no complaints about the built-in sorting functions
themselves.  It's the priority calculation.  I guess priority-down would
show that problem most clearly.  I have a lot of tasks, so I've altered the
priority calculation to produce a larger number for each item, like this:

(defun org-get-priority (s)
  "Find priority cookie and return priority."
  (save-match-data
    (if (functionp org-get-priority-function)
    (funcall org-get-priority-function)
      (if (not (string-match org-priority-regexp s))
      (* org-custom-sorting-intensity (- org-lowest-priority
org-default-priority))
    (* org-custom-sorting-intensity (- org-lowest-priority
           (string-to-char (match-string 2 s))))))))

custom-sorting-intensity is usually around 4500, so I get large numbers and
therefore lots of gradations.  But this is just takes care of the
priority-cookie part of the calculation.

My issue is that incrementing the calculated priority by 1 for each day
past due is not dramatic enough when using these large numbers. I'd like it
to be 100 instead.  Or even, just to get crazy, 100 for each day past
deadline and 50 for each day past scheduled due date!

I know that I should be doing this as a user-defined-function for
org-agenda-sorting-strategy, but I don't understand how.  The documentation
is clear, I'm just not very good with lisp.  So I've copied the function
from org.el into my .org file and tweaked it a little.  That's why I'm
looking for the part of org.el or whichever file that increases calculated
priority according to number of days past deadline.


Thanks,
Inanna

Sorry, I misspoke.  What I meant to say was that I altered org-get-priority
to keep priority cookies more significant than due dates.
