Afternoon. Does anyone know why a defrecord fails when implementing a protocol from another ns but not when one implementing one from its own ns?

$ nbb -v
nbb v1.2.179

$ nbb -e '(ns storage) (defprotocol IStorage (-store [_ foo])) (ns user [:require [storage]]) (defrecord Storage [] storage/IStorage (-store [_ foo] (prn :foo foo))) (-store (->Storage) :hoo)'
----- Error --------------------------------------
Message:  Could not resolve symbol: -store
Location: 1:157
Phase:    analysis

----- Stack trace --------------------------------
user - <expr>:1:157

Could not resolve symbol: -store

 $ nbb -e '(defprotocol IStorage (-store [_ foo])) (defrecord Storage [] IStorage (-store [_ foo] (prn :foo foo))) (-store (->Storage) :hoo)'
:foo :hoo

Asking about this because I’m trying to run https://github.com/logseq/datascript/blob/51fe8d3fc95056bb82553b3803e5994d194206b4/test/datascript/test/storage.cljs#L11-L13 through nbb’s sci and it also fails to resolve the protocol’s method name

The issue is not the protocol extension, but your call at the end, this should be:

(storage/-store (->Storage) :hoo)

borkdude 2023-12-06T22:05:41.898209Z

protocol functions/vars aren't automatically referred or so

Ah yep. Thanks. My mistake in trying to make the smallest repro. The original bug I’m seeing isn’t able to load the defprotocol:

bb test                                                                                   [16:34:51]

This is in the context of running datascript tests through a custom nbb in nbb-features

maybe you can make another repro?

2023-12-06T22:12:00.183569Z

Sure. I’ll open up a sci issue with full repro. I thought I’d sanity check ask before doing so but it sounds like this should work

borkdude 2023-12-06T22:12:27.655549Z

ok make a tiny repro that works 100% in CLJ(s) and not in SCI and I'll have a look tomorrow

2023-12-06T22:13:12.809879Z

Sure. Thanks
