There exist functions to set tags, keywords, and priority values (org-set-tags-to, org-todo, and org-priority respectively), but what about setting the heading (item) itself?

For example:

*** TODO [#B] Some existing heading                      :URGENT:

(my/org-set-heading "The new heading")

*** TODO [#B] The new heading                            :URGENT:

Setting the heading is non-trivial; the logic needs to be mindful of outline folding, heading stars, the priority label, and tags-- at the very least. Is there an org function that accomplishes this (or a 3rd-party library that includes one)?

I haven't found any org functions that accomplish this, but my apropos-fu has certainly failed me before.

A fairly thorough search suggests that I'll need to employ org-complex-heading-regexp, special care to the subtree/folding, and possibly a patch request.

Here is a way to get there with org-dp (https://github.com/tj64/org-dp, and its on MELPA):

(require 'org-dp)

(let ((hl (progn
        (outline-previous-heading)
        (org-element-context))))

  (org-dp-rewire
   nil ;; type.
   (buffer-substring (org-element-property :contents-begin hl)
             (org-element-property :contents-end hl))
   t ;; replace
   '(:title "new headline")
   hl))

You could wrap this in a function that sets the title to what you want. I think org-dp-rewire is what you want.

  • This does the trick in setting the heading, but creates an issue of its own. It inserts an org 'NAME' keyword (#+NAME: ) line immediately before the modified heading. Do you observe this same behavior? – ebpa Dec 6 '16 at 1:40
  • no I don't see that. I am using org 9, and org-dp from MELPA today. – John Kitchin Dec 6 '16 at 2:05

    I just noticed if the headline has a NAME property then I see that. I am not sure what to do about that. Maybe raise it as an issue with org-dp. – John Kitchin Dec 6 '16 at 2:20
  • Nice catch! 👏👏 I was in the process of upgrading to 9 and hadn't started troubleshooting yet. Indeed the headings have "name" properties. I'll create an issue on org-dp. The org name keyword probably needs a prefixed syntax in org-dp. – ebpa Dec 6 '16 at 2:27

Out of the box org-mode provides a function called org-edit-headline, which changes the title and doesn't mess with todo state, priority or tags.

(org-edit-headline "The new heading")

Hope it helps.
