Hi all,
the following function has served me well for a few years, so I thought
I'd share it. I would even be happy to contribute it to the codebase of
org-mode (core or contrib); however in this case someone would have to
point me to a fool-proof guide for how to do this. I know that for
contributing code I will have to sign some FSF copyright forms, and I
know how to use git, but I don't know the exact org-mode specific steps
of doing so.
--- %< --- %< --- %< --- %< --- %< --- %< --- %< --- %< --- %< --- %< ---
(defun org-jump-to-id ()
"Asks for an identifier and searches for the first entry in the
current file that has this identifier as a CUSTOM_ID property."
(interactive)
(let* ((property "CUSTOM_ID")
(custom-id (org-icompleting-read "CUSTOM_ID of entry: "
(mapcar 'list
(org-property-values property)))))
(org-link-search (concat "#" custom-id))))
(define-key org-mode-map (kbd "\C-cj") 'org-jump-to-id)
--- %< --- %< --- %< --- %< --- %< --- %< --- %< --- %< --- %< --- %< ---
This implementation works efficiently in a 4 MB org file with 100 IDs.
Together with ido or helm I find it a very user-friendly way of jumping
to frequently used headlines.
I noticed that org-babel-ref-goto-headline-id does something similar, so
maybe some code could be shared among the two functions.
Cheers,
Christoph

The problem is that we're running out of interesting keybindings. "C-c
j" is not an option since it is reserved to users.
Another option would be to add it to Worg.

Note that you can use
(let ((h (org-find-property "CUSTOM_ID" custom-id)))
(when h (goto-char h)))
instead of
(org-link-search ...)
for one less level of indirection.

Indeed. I modified it so it uses `org-find-property'.

Let me ask the question differently: as all reasonable key bindings are
taken (a statement to which I tend to agree), is the suggestion of
interactive functions to be added to the core of org-mode no longer
appropriate? I.e. should I contribute them to Worg (with which I still need
to familiarise myself) rather than suggesting them here? Or, asking about a
middle course, what's the role of org's "contrib" directory? (Is it even
suitable for something that is not a complete plugin of its own right, but
rather just a single function?)
> "C-c

Sorry, this was unfortunate in my initial post. I didn't intend to
hard-code this as the "default" key binding, but it was rather meant to be
read as "if you like this function, you could bind it, for example, to ...".

Thanks - makes sense. However probably not if I write a tutorial in the
style of "if you want to do <something>, then copy the following lines to
your. emacs".
But I think I should rather aim at Worg's "contrib" directory, with a short
elisp file containing my function, plus a short HTML file explaining that
there exists an elisp file containing a function that does <a few words
about the functionality> - does this make sense?
Cheers, and thanks for your advice,
Christoph

IMO we can't afford maintaining all end-user functions imaginable in
"org.el". What is possible, however is to extend some existing
behaviour.
For example, `org-open-at-point' could be a good candidate: with C-u
C-u, it could offer to type in a link and open it. So, in order to jump
to a custom-id, you can use
C-u C-u C-o #my-custom RET
Of course, you lose completion, in this case, which is a serious
drawback.
Another option would be to extend `org-goto' (C-c C-j) and offer to jump
to custom-id.
> But I think I should rather aim at Worg's "contrib" directory,
There's no such thing as Worg "contrib" directory. There's Worg, OT1H,
and a contrib/ directory OTOH, but they are not related.
Worg is a good place to share useful code snippets.

* Non-technical feedback ::
- Thank you so much for sharing. I've been looking for something like this for a while.
- I hope it'll make it into org-mode some way or another, it seems like a valuable addition.
- imho the HELM integration is essential.
