[Feature proposal] add the scope limit to denote-missing-links

[jarofromel]

Hello,
I create the metanote (index) which contains the links to my denote files. Each heading in the metanote represents one tag and there are links to files with this tag. I use denote-org-extras-dblock-insert-backlinks to check that I had indexed all the tagged files. But in the case of files with two more tags the link can be already included in the metanote. See example below:

* tag DBMS
[[link to file1_dbms_emacs]]

* tag EMACS
#+BEGIN: denote-missing-links :regexp "_emacs"
nothing is found because there is already one link to the file1_dbms_emacs
#+END

The scope limiting parameter in the dynamic block would solve this situation (:scope heading/file). Thanks for potentially considering this.
Maybe there is simpler solution, but I didn't find it yet.

I see. Please help me understand this better. What kind of values do you think the scope should accept? Maybe file and heading? Is there another scenario?

[jarofromel]

From the similar functionalities:
org clock table dblock - :scope header arg
org column view dblock - :id header arg
org-ql dblock - :from header arg

I think current buffer (or file) and current subtree would be good enough for most usecases.
Other "nice to haves" (inspired by the links above) are (sorted by usefulness as I see it):

• region, treeN (surrounding trees), filename (other file than the current one), function (returning filenames), heading (returning heading)

[protesilaos]

This is a good idea. Though it will need to eventually be generalised for all the dynamic blocks we have. As such, I think we must first consolidate everything into a single denote block and then add the new feature.

Sure. I am not yet on the level to enhance denote codebase but I am happy to test and try.
