Hi. I've been using Emacs since the 80's but I'm a new org mode user.
What a fantastic piece of software. I had used my own todo mode, but org
is orders of magnitude better. Thank you!
My main todo file defines various TODO keywords and initial state like this:
#+STARTUP: indent overview
#+TODO: @NOW @NEXT @WIP @PENDING
What I really want is to initially only see items noted with those TODO
keywords and also due items. Everything else should be hidden.
Since I didn't see an out-of-the-box way to do this, I hacked the following
together. The purpose of this email is to see if this is the right way (or
a good way).
The hack starts with this at the end of the org file:
* Local Variables
;; Local Variables:
;; eval: (save-window-excursion (my-org-show-sparse-todo-tree))
;; End:
That function is defined thus:
(defun my-org-show-sparse-todo-tree ()
(interactive)
(message
"%d TODO entries found"
(org-occur (concat "^" org-outline-regexp " *"
"\\("
(mapconcat 'identity org-todo-keywords-1 "\\|")
"\\)\\>")))
;; events due before 2 weeks from now:
(org-check-before-date
(format-time-string "%Y-%m-%d" (time-add nil (* 3600 8 14)))
t))
which relies on the redefined version of org-check-before-date, so
keep-previous is passed to org-occur:
(defun org-check-before-date (d &optional keep-previous)
"Check if there are deadlines or scheduled entries before date D.
Optional argument KEEP-PREVIOUS is passed directly to `org-occur'."
(interactive (list (org-read-date)))
(let* ((case-fold-search nil)
(regexp (org-re-timestamp org-ts-type))
(ts-type org-ts-type)
(callback
(lambda ()
(let ((match (match-string 1)))
(and (if (memq ts-type '(active inactive all))
(eq (org-element-type (save-excursion
(backward-char)
(org-element-context)))
'timestamp)
(org-at-planning-p))
(time-less-p
(org-time-string-to-time match)
(org-time-string-to-time d)))))))
(message "%d entries before %s"
(org-occur regexp keep-previous callback)
d)))
I find this shows me exactly what I want to see when I finish a task and
want to start something new.
If this is the right way and the maintainer wants me to submit a patch, I
would include these functions to get a new optional for keep-previous,
since they could all plausibly be used for the same thing that
org-check-before-date was:
* org-show-todo-tree
* org-check-deadlines
* org-check-before-date
* org-check-after-date
* org-check-dates-range
Thank you.
Kevin

I think you can use `org-match-sparse-tree'. It supports the general
match syntax. See 11.3.3 Matching tags and properties section for the
match syntax.

I think that it does make sense to support KEEP-PREVIOUS in these
functions. `org-occur' does support it and there is no reason not to
allow the same toggle in the listed functions.
