Show backlinks from :PROPERTIES:

[zetashift]

So I have a reading list, with books for example:

* TOREAD Book Name
:PROPERTIES:
:author: [[id:734f176d-f598-460c-a2f9-c134e5d339ca][Author Name]]  
:END:

Now when I'm on the authors page I expect to see backlink to the that properties drawer/book name. Currently the quickfix window is completely empty.
Is it possible to do this or is there maybe a better way to organize this?

Does orgmode support links in the properties drawer? This plugin uses nvim-orgmode to find links within a file and then index id links, so it would need to be handled upstream in that plugin to support links there. In the meantime, you'd need to include your link somewhere else (heading or body) for it to be available.

So in Doom Emacs I can go to links in properties drawer, but from looking around this seems to be not-according-to-spec.

From: https://www.orgroam.com/manual.html

Org-roam relied on the obtained Org AST for the buffer to parse links. However, links appearing in some places (e.g. within property drawers) are not considered by the Org AST to be links. Therefore, Org-roam takes special care of additionally trying to process these links. Use org-roam-db-extra-links-elements to specify which additional Org AST element types to consider.

If the org AST doesn't support links in property drawers by default, then I don't believe nvim-orgmode will support them, either.

I'm totally happy to have this feature added to this plugin, but can't guarantee I'll get to this myself. Happy to review a pull request, though!

I believe that's completely fair!

Well it doesn't help that I'm new to orgmode/neovim as well :P.
I could atleast attempt it, I'm not sure where to start, wouldn't this require a change in the tree-sitter parser to identify links in the PROPERTIES drawer?

[kristijanhusak]

You can see how it's done in nvim-orgmode https://github.com/nvim-orgmode/orgmode/blob/master/lua/orgmode/files/file.lua#L679-L697.

Oh that is pretty cool!

That would entail something like this:

  local ts_query = ts_utils.get_query([[
      (paragraph (expr) @links)
      (drawer (contents (expr) @links))
      (property_drawer (value (value) @links))
      (headline (item (expr)) @links)
  ]])

The (property_drawer (value (value) @links)) got added in?

[kristijanhusak]

@zetashift yes, something like that, but you would need to write the surrounding logic also to get the links for org-roam.
