Referencing TODO items

Referencing TODO items

[Paulo Matos]

Hi,

I have a TODO item that got stuck due to some unforseen circumstances.
Another TODO item is needed as a workaround therefore I have something like:

* TODO Implement using hash tables
  :LOGBOOK:
  - Note taken on ... \\
  Stuck because...
  :END:

* TODO Implement using hand written maps
  This is required because todo item REF was stuck. If unstuck, we can
remove this implementation.

How can I REF the first TODO item in the second?

Thanks,

do M-x org-store-link on the first TODO item and M-x org-insert-link
where you want to reference the first TODO item.

Interesting but it doesn't really work properly.

My TODO looks like:

* TODO add support for %lo and %hi operands in offsets

I create the link and the link has the name of the todo headline.
When I try to follow with C-c C-o, it says 'No match - create a new
heading?'. If I say yes, a new heading is created in my document that
looks like:

* *add support for ^@ and ^@ operands in offsets

I am curious why %hi and %lo would cause any troubles...

I can confirm that behaviour, but it doesn't bother me, because I use ;):

(setq org-id-link-to-org-use-id 'create-if-interactive)

When I looked at it, it sounded that the only thing it does it to
automatically create the heading without prompting, however I ran into
troubles when testing. My org-mode doesn't have that variable (9.1.2)
and even if it did it wouldn't solve the problem (assuming I am correct
about its intended behaviour since I don't want a new heading, I want to
follow the link to the existing heading.

it is from org-id. It gives the heading a unique id and uses that to
reference the heading instead of the heading's text. That way the
reference does not become invalid if the heading's text changes. And, as
a side effect, it works around the problem you found.

No, it doesn't solve the problem. I guess the problem is that the
heading's text is fed to a format form or something like that.

This is because % are not properly escaped, so `org-link-unescape'
turns %hi into ^@.

This is now fixed. Thank you.

This is a nice feature/solution but I'd like to point out to others reading it that there may be a better option that uses custom IDs if they exist:

(setq org-id-link-to-org-use-id 'create-if-interactive-and-no-custom-id)

  -k.

org-id should be part of the org package as well as of the
org-plus-contrib package.
