I actually got curious and gave this a try and here's what I came up with:
test.org:
* a
** b
*** h
** b
*** q
 h
** c
*** d

Elisp:
(defun goto-notes ()
  (interactive)
  (find-file "~/test.org")
  (org-goto-subtree '("a" "b" "q" "h"))
  (org-show-context)
  (org-show-entry)
  (show-children))

(defun org-goto-subtree (path)
  (let ((level 1))
(org-element-map
(org-element-parse-buffer 'headline)
'headline
(lambda (x)
  (if (< (org-element-property :level x) level)
  (setq level (org-element-property :level x)))
  (if (and (= level (org-element-property :level x))
   (string= (nth (- level 1) path) (org-element-property
:raw-value x)))
  (progn (setq level (+ level 1))
 (if (> level (list-length path))
 (goto-char (org-element-property :begin x))
nil t)))

My very first attempt at programming Elisp so any feedback is appreciated.

Best regards

Thanks alot! This is exactly what I was asking for. This will suffice for me 
now.
Maybe some day I will learn some LISP and teach it to navigate the hierarchical 
structure.

More specific example, let's say I want to bind keys in my .emacs file:

"C-c b" -> find "gtd.org" and jump to "Projects/Work/Bugs"
"C-c m" -> find "gtd.org" and jump to "Projects/Work/Meetings"

I've looked at that function aswell but it seems even harder to achieve 
what I want with: Call it from lisp without any user interaction. If you think
that is possible I would love an example.

[O] Go to heading using LISP

2013-06-08 Thread Alexander Wingård
Hi!

I want to create special key-bindings that use the org-refile goto
interface to jump to specific headings.

My initial attempt was:
(org-refile 4 "gtd.org" "Projects/Work/Bugs")

But it seems specifying RFLOC is not that simple.

Someone have any idea how to achieve this or another way to jump to a
heading?

Wonderful, thanks alot!

I can already see this becoming of great use to me.

Re: [O] Time range between now and timestamp

2011-09-15 Thread Alexander Wingård
Let's say I have this:

<2011-09-15 Thu>--<2011-09-16 Fri>

and I put my cursor over this and press C-c C-y my minibuffer will
spit out 1 day.

I would like a command that does the same thing if i execute it over
just <2011-09-16 Fri>.

Sometimes I'm interested in how much time there is left to a specific
appointment.

[O] Time range between now and timestamp

2011-09-15 Thread Alexander Wingård
Hi!

I really would want to have a command that given the cursor is over a timestamp 
would output the time-range from the current time to that timestamp.

I've been searching a lot for this but no luck and I even did an attempt to 
implement some hacked version of org-evaluate-time-range and org-days-to-time 
but since my experience with lisp is absolutely zero I failed miserably.

I imagine someone here could help me whip this up in a couple of lines or maybe 
such feature can already be achieved?

Best Regards /Alexander

Ps. I love org-mode
