Hi. Are custom query functions supported? I'm using the datalevin babashka pod and get the following error when trying to use a custom query function: Unknown function 'my-fn in [(my-fn) ?greeting]

(defn my-fn
    []
    "hello")

  (d/q '[:find ?greeting
         :in $
         :where
         [(my-fn) ?greeting]]
       (d/db conn))

Query function is supported in Datalevin if you use from Clojure. But if you are using babashka, you will need to make sure your function is available for Datalevin’s sci (https://github.com/babashka/sci)

i have not tried this use case, so if you want to do some investigation and figure out what’s missing, that would be great

datalevin uses its own copy of sci, so it does not know about your function that’s defined in babashka’s sci

i think that’s the issue

if you don’t have time to investigate, file an issue, i will see if I can get around to take a look

Thanks. I'll do some investigation later on and file an issue if I'm not able to figure it out
