Get a list of pages that refer to the current page?

Questions & Help Queries
1

While the Linked References section is useful, it’s usually just too much information for my needs.
What would really help me is a simple list of page links.

Example: In a page called Page One, which is mentioned in pages A, B, and C the query would return something like: [[A]], [[B]], [[C]].

I have great trouble figuring out how to use queries, but I find it hard to believe that this isn’t possible.
Can someone help me out?

Would the Local Graph / Page Graph be a possible alternative?

Well, yeah, but it’d be “friction-y” for my workflow.
I’m used to seeing information arranged in a particular way, and I’d prefer to make the tool fit my preferences than the other way round.

Would this be a result you can use?

#+BEGIN_QUERY
{:query [:find ?tag
   :in $ ?current
   :where
     [?p :block/name ?current]
     [?b :block/refs ?p]
     [?b :block/page ?page]
     [?page :block/name ?tag]
 ]
 :inputs [:current-page]
 :result-transform (fn [result] (sort result))
 :view (fn [tags] [:div (for [tag (flatten tags)] [:a.tag.mr-1 {:href (str "#/page/" tag)} (str "#" tag)] )] )
}
#+END_QUERY

Wow. Yup, that’s basically it.
Don’t really need the links to appear as tags, but I’m pretty sure I can now figure any further tweaks myself.

Thanks very much!

(I feel compelled to add, however, that I really don’t understand how such a simple result requires so much weird code. But that’s a rant for another day.)

We can argue over “weird code” :joy:
But essentially the first part is just getting the actual data. We have a page, then we have a block that references that page, and finally we have a page that the block is on. We return the name of that last page in :find ?tag.
The :result-transform sorts the result, feel free to omit I guess.
And the :view determines how it is displayed.
You can change that view in any number of ways to change how the result is viewed.
Without the :view you get the raw data, basically one long string without spaces.
I was experimenting a little and you technically don’t need all aspects of the view.
(fn [tags] ...) is just defining a function with input labeled tags.
(for [tag (flatten tags)] ...) is basically flatten tags to a string and then for each of the items in tags.
[:a ...] is where the link is made with the type .tag.mr-1 actually ensure you have spaces between the tags.
(str ...) is a concert to string and also concatenate. Add #/page/ to the result, for the link url part and add # to the result for the link text part.
It’s just what you deem weird. The view transforms raw data into something readable.

If you want a simple vertical list you can try this query instead.

#+BEGIN_QUERY
{:query [:find (pull ?page [*])
   :in $ ?current
   :where
     [?p :block/name ?current]
     [?b :block/refs ?p]
     [?b :block/page ?page]
 ]
 :inputs [:current-page]
}
#+END_QUERY

Thanks for the explanation. I kind of figured it out just be reading the query, but I do appreciate you taking the time to provide such a lucid description.

Like I wrote earlier, I’ll leave discussions of syntax to another day. No point cluttering things up here.

what if my page has alias? I cannot use this query to find pages refer to alias.
Thanks!

Welcome. You may utilize attribute :block/alias (e.g. like here, but read about the mistake).
