Just reviewing the docs on custom defnc and reflecting on this line: ~(merge default-opts opts). One major downside to this is that you can't do a partial override of the options, e.g. {:helix/features {:define-factory true}} will accidentally turn off fast-refresh. I was thinking of instead using ~(assoc (merge default-opts opts) :helix/features (merge (:helix/features default-opts) (:helix/features opts))) on the basis that all the helix features can be turned off as easily as on (e.g. the replace mode isn't required)

Just spotted https://github.com/lilactown/helix/blob/master/resources/clj-kondo.exports/lilactown/helix/config.edn#L1. This didn't work for us, and we ended up expanding to:

(defn ~name [& ~@args] ~@body)

ack, thanks!

I would accept PRs for both of those improvements

I'm still a little fuzzy on the clj-kondo config.

@dominicm @lilactown not sure if is the issue here, but I have two things that help me to make the foreign clj-kondo config works: 1. on the Helix side, make sure resources is present on classpath 2. on the project client side, use clj-kondo --copy-configs --dependencies --lint "$(clojure -Spath -A:provided:dev)" --parallel to make kondo copy over the configs
