Non-conforming function call does not show reason

[majnu]

Wow, ghostwheel is really great, thanks!

One thing that I don't get to work is this:

(>defn add-positives
  [a b]
  [pos-int? pos-int? => int?]
  (+ a b))

Calling (add-positives -1 1) rightfully detects a non-conforming argument, but does not show which argument did not conform and why:

Error: Call to #'shadow-cljs-browser-template.core/add-positives did not conform to spec.

My namespace is declared like this:

(ns shadow-cljs-browser-template.core
  #:ghostwheel.core{:check     true
                    :num-tests 10
                    :instrument true
                    }
  (:require
    [ghostwheel.core :as g :refer [>defn >defn- >fdef => | <- ?]]
    [ghostwheel.tracer]
    [clojure.pprint :as pp]))

Am I missing something?

I can reproduce this. I'm just tweaking a few things to make Ghostwheel play nice with the newest versions of Shadow CLJS and Figwheel and will look into this in the process.

P.S. In the meantime you can see the raw error including all relevant details in the JS console.

Great thanks! I am indeed having some more issues with ghostwheel and shadowCLJS. Will wait for that update before I try again.

👋 Hi. I'm posting this same comment to all issue threads to just give a quick heads up that the project, despite rumours and some evidence to the contrary, is not dead. It was hibernating for a little while and now nearing the long-awaited next release, which will fix some long-standing issues (and introduce some breaking changes to the config).

I'll be reviewing all open issues and PRs over the next couple of weeks, so stay tuned and thanks for the patience.
