or is there a way to get subscription value for a given app db value? there are some subscriptions chains that have logic I would rather not duplicate

I made the following hack workaround to get the value of a sub:

(defn- get-subscription-value [db sub]
  (let [handler-fn (re-frame.registrar/get-handler :sub (first sub))]
    (handler-fn db sub)))

(defn subscribe-val
  "Get value of subscription for the given db."
  [db subv]
  (with-redefs [re-frame.subs/subscribe (partial get-subscription-value db)]
    @(rf/subscribe subv)))

That hack should still produce a warning if one of those subs uses a signal sub. And if it doesn't, it's not entirely correct because the cache wouldn't be purged. I think. I ended up writing my own wrappers or alternative variants for most of re-frame API that I use. Can definitely recommend - it gives great flexibility. E.g. for this particular case, I've introduced a dynamic variable that, when set, is just like subscribe but without caching.

it doesn’t with the redef

Oh, hmm. Does that work properly with advanced optimizations as well?

that remains to be seen

ah yes, it seems re-frame.subs/subscribe should have ^:dynamic meta for it to work in advanced compilation

Right. I pretty much never use with-redefs so my memory is always fuzzy when it comes to it.

I might need to make my own wrapper for subscribe and use that when I need this

Although, docstrings in both CLJ and CLJS don't mention :dynamic. How did you come to the conclusion that it's needed?

or setting static-fns to false, but I don’t want a performance hit everywhere

Thanks! Yeah, makes sense.

Make sure you're not falling for the "rookie mistake" described in this section: https://github.com/reagent-project/reagent/blob/master/doc/CreatingReagentComponents.md#form-2--a-function-returning-a-function

Same applies for a form-3 component.

@U2FRKM4TW a-HA, I just changed a form 1 to form 2!

That was precisely it
