[emacs-wiki-discuss] More flexibly named "Time" pages

[Greg Novak]

As it stands, the only time period Planner knows about are days.  There are 
Project pages and each task must be scheduled onto a specific day. I'd like 
Planner to know about weeks, months, etc, and so far I've been doing this by 
hand.

Specifically, I'd like pages like 2005.August, 2005.September.Week1, 2005.Year, 
etc, to be treated just like day pages are treated now.  I'd like to be able to 
use planner-copy-or-move-task to reschedule a task from 2005.September.Week1 to 
2005.September.Week2, for instance.  In a perfect world, these tasks would be 
swept forward onto the next week/month/whatever page just like uncompleted 
tasks on day pages are now, but let's leave that for the future...

The obvious way to achive this is to hack planner-date-regexp to recognize the 
more liberal date name format.  I looked into this a bit, and in many places it 
seems like this will work (the code is calling (string-match 
planner-date-regexp name) as a simple true/false test), but in other places 
(for example in planner-appt) the code uses match-string to extract years, 
months, and days after using planner-date-regexp.

My question for people more familiar with the internals of Planner is: Is there 
a slicker way to do this that I've just missed?  If not, does anyone have any 
opinions about how this should be done?  I'd imagine defining 
"planner-time-page-regexp" and then changing code that currently uses 
planner-date-regexp as a true/false test to use the new regexp.

Thanks for your help,
Greg
