Q : select current org item as region

Q : select current org item as region

[Richard Riley]

What would be the best elisp way to select the current org entry? I want
a hot key to select the current item as current region (not into the
clipboard).

The problem I am having is that org-in-item-p is returning nil even
though the point is in an org-item. Is the docstring where it mentions
"hand-formatted item" more significant that I understand? As a result
org-beginning-of-item is failing

Currently the function I have is (not working but to give you the idea
of what I am trying to accomplish):

    (defun rgr/org-blog-entry ()
      (interactive)
      (save-excursion 
            (org-beginning-of-item)
            (set-mark-command)
            (org-end-of-item)
            (let((tmpbuf (make-temp-file)))
              (org-export-as-html nil nil tmpbuf t))))

OK, minus several million for me for not digging  deep enough. "item" is
not an org item per se but a list item. I need the entry functions. So
its taking shape (but not working yet ..) as 

  (defun rgr/org-blog-entry ()
    (interactive)
    (save-excursion 
          (goto-char (org-entry-beginning-position))
          (set-mark (org-entry-end-position))
          (let((tmpfile (make-temp-file "org-blog-html-")))
            (org-export-as-html nil nil (find-file-noselect tmpfile) t))))

I now have a working function to blog the current org-entry to google
blogs (blogger,blogspot) . See new thread "Blogging org entries using
google command line".

Could you elaborate on that? Could you give a minimal example? If
`org-in-item-p' is returning nil whereas you are in an item, there is
definitely a bug to fix.

Here is a suggestion to mark current item:

(defun mark-current-item ()
  (interactive)
  (when (org-in-item-p)
    (goto-char (org-get-item-beginning))
    (push-mark nil t t)
    (goto-char (org-get-end-of-item (org-list-bottom-point)))))

Interesting -- looks like a good candidate for worg/org-hacks.org

Maybe with variants like

- narrowing to the item
- selecting it (depending on transient-mark-mode)
- cloning it
- killing it*

... just a thought.

* Would people would find it to have C-k to kill a whole item if a
  certain option is set?  I think I would.  It's rare to have to kill 
  a line in a list item without having to kill the whole item.

This is mine:

--8<---------------cut here---------------start------------->8---
(defun stl/outline-mark-subtree ()
  "Mark the current subtree in an outlined document.
This puts point at the start of the current subtree, and mark at the start
of the next."
  (interactive)
  (let ((beg))
    (if (outline-on-heading-p)
	;; we are already looking at a heading
	(beginning-of-line)
      ;; else go back to previous heading
      (outline-previous-visible-heading 1))
    (setq beg (point))
    (outline-end-of-subtree)
    (outline-next-visible-heading 1) ; just before the next heading (stl)
    (push-mark (point) nil t)
    (goto-char beg)))
--8<---------------cut here---------------end--------------->8---

it's derived from the original outline-mark subtree but marks an empty
space before a next-same-level-heading.

Thanks for the replies.

Just for google completeness

      (goto-char (org-entry-beginning-position))
      (set-mark (org-entry-end-position))

seemed the most efficient after digging about a bit.

As a side note,

(goto-char (org-entry-beginning-position))

is in fact a convoluted way (if you don't need point value) of calling

(outline-back-to-heading t)

so I doubt this is the "most efficient" in this case.

Good spot - but I will probably stick to the org- functions in general
in case they are ever expanded for whatever reasons.

The speed overhead in an interactive environment is pretty much zero ;)

It's not the same, it does not include the subtree. Take for example:

--8<---------------cut here---------------start------------->8---
* Top 1
  Some text in the Top 1 node
** Bottom 1
   Some more text.
** Bottom 2
   No text at all
* Top 2
  Another toplevel entry.
--8<---------------cut here---------------end--------------->8---

If you place point on the second line of the above example,
(stl/)?outline-mark function will mark: Top 1, Bottom 1 and Bottom 2,
nodes with their content. While the org-entry-(beginning|end)-position
will provide you only with Top 1 heading and a text before Bottom 1.

Hi Lukasz,

You are right and sub trees should be included. I was just looking at that
while refitting the core blog part to be called more generally.

I used :

      (org-forward-same-level 1 t)

to do the same.

http://github.com/rileyrg/org-googlecl/blob/subtrees-0.01/org-googlecl.el

Seems to be working ok now.
