Retrieving all invalid references

Questions & Help
1

Hi, sometimes when I edit my page, I would sometimes remove a block or two, which might cause some blocks’ references invalid.
I am wondering if there is some way to retrieve all invalid references. Thanks!

You can check out GitHub - logseq/graph-validator: Validate your logseq graphs

Agree this would be a nice feature. I have a python script to find invalid block references for now. It works for me and might be of some use to others

Hi, inspired by Advanced queries for Logseq - gist.github.com/, I found this query very helpful

#+BEGIN_QUERY 
{:title "Broken References"
:query [:find (pull ?b [*])
		:where
		[?b :block/refs ?t]
		[(missing? $ ?t :block/name)]
		[(missing? $ ?t :block/content)]]
}
#+END_QUERY

I didn’t check it further so I cannot say for sure that all broken references are catched by the query.

Thanks for sharing this @vou. Looks like the query is updated now.

Below is the updated query

#+BEGIN_QUERY 
{:title "Broken References"
 :query [:find (pull ?b [*])
         :in $ ?matcher
         :where
         [(re-pattern ?matcher) ?regex]
         [?b :block/content ?c]
         [(re-find ?regex ?c)]
         [(missing? $ ?b :block/refs)]]
 :inputs [ "\\([0-9a-f]{8}-[0-9a-f]{4}-[0-9a-f]{4}-[0-9a-f]{4}-[0-9a-f]{12}\\)"]
 }
#+END_QUERY

Also I had a similar question posted here - not for broken references, but for invalid references:
