Hi all,
If my cursor is in a description list item, what's the recommended way of
getting the point at the beginning of the description list text (i.e.,
after the bullet character)? To illustrate, given the following description
list item, I'd like to get the point represented by the pipe character "|":
- |foo :: bar
If I use something like `(org-element-property :contents-begin
(org-element-at-point))`, that gives me the point at the beginning of the
description, not the list item:
- foo :: |bar
How do I need to massage this to give me the beginning of the whole list
item? Is there a recommended solution that'd work for both description
lists *and* plain lists?
Thanks everyone :)
Calvin

This is very un-orgish but it seems to do it. (forward-word) goes to the
end the next recognized word, (backward-word) to the beginning of the
word you are now at the end of, and (backward-char) to get to a
space. You just need org to get you on the list ;)
It seems to work on these.
- foo :: bar (goto-char (org-element-property :contents-begin (org-element-at-point)))
- baz :: goo
- 1 egg
- 0.5 cups
- :punc
#+BEGIN_SRC emacs-lisp
(defun gg ()
(interactive)
(beginning-of-line)
(forward-word)
(backward-word)
(while (not (looking-at " "))
(backward-char)))
#+END_SRC

Ah, this makes sense. Unfortunately, an additional constraint I failed to
mention in the first email is that it'd be nice if the solution worked for
numbered lists as well. That solution unfortunately breaks on numbered
lists :(
Is there perhaps another way to accomplish this?
P.S. I just noticed the typo in "position" in the subject of this
thread...apols, how very embarrassing of me.

This seems to work for me:
(defun yf/org-beginning-of-item ()
(let ((element (org-element-at-point)))
;; 'plain-list is returned when at the beginning of the first item in the list.
(when (eq 'plain-list (org-element-type element))
(save-excursion
(forward-char)
(setq element (org-element-at-point))))
;; look ancestors to find an 'item element.
(while (and element
(not
(eq 'item
(org-element-type element))))
(setq element (org-element-property :parent element)))
(if (not element)
(error "Not in a list item")
(goto-char
(+ (length (org-element-property :bullet element))
(org-element-property :begin element))))))
Probably one could use the list API directly (from org-list.el) too.

Indeed, I'd definitely go for the org-list stuff. It's a bit confusing
at first, because it isn't like any of the other org code, but it works
well. Try calling `org-list-struct' on a list; that will probably give
you most of what you need.

See `org-special-ctrl-a/e'.
