Hi,
Here are three functions related to todo and deadline highlighting is
the todo buffer. The first lets you highlight upoming deadlines and
todo items at the same time.
(defun org-check-deadlines-and-todos (ndays)
(org-check-deadlines ndays)
(flet ((org-remove-occur-highlights (&optional beg end noremove))
(org-overview ()))
(org-show-todo-tree nil)))
It would be nice to be able to tell the org-occur function not to
remove existing highlights in a less hacky way. Another suggestion:
explicit specification of the face used for highlighting so that
deadlines and todos could use a different face. Yet another
suggestion: the org-occur callback could return the face to use, so
that different faces could be used for deadline highlighting,
depending on the urgency of the deadline (ie. in 3 days vs. in 30
days).
The following two functions redefine org-show-todo-tree, so that TODO
items SCHEDULED for the future are not highlighted. Only
non-scheduled TODO items or TODO items scheduled for the past or
present are highlighted. The SCHEDULED directive must be on the same
line as the TODO keyword.
(defun org-todo-is-current ()
"Checks whether a TODO items is current."
(if (re-search-forward org-scheduled-time-regexp (point-at-eol) t)
(let ((today (calendar-absolute-from-gregorian
(calendar-current-date)))
(timestamp (time-to-days
(org-time-string-to-time (match-string 1)))))
(<= timestamp today))
t))
(defun org-show-todo-tree (arg)
"Make a compact tree which shows all headlines marked with TODO.
The tree will show the lines where the regexp matches, and all higher
headlines above the match.
With \\[universal-argument] prefix, also show the DONE entries.
With a numeric prefix N, construct a sparse tree for the Nth element
of `org-todo-keywords'."
(interactive "P")
(let ((case-fold-search nil)
(kwd-re
(cond ((null arg) org-not-done-regexp)
((equal arg '(4)) org-todo-regexp)
((<= (prefix-numeric-value arg) (length org-todo-keywords))
(regexp-quote (nth (1- (prefix-numeric-value arg))
org-todo-keywords)))
(t (error "Invalid prefix argument: %s" arg)))))
(message "%d TODO entries found"
(org-occur (concat "^" outline-regexp " +" kwd-re )
'org-todo-is-current))))
