Footnotes

1. Due to the way that macros are expanded in ClojureScript, you'll need to configure Expound in Clojure. This does not apply to self-hosted ClojureScript.

   (Note the -e arg below)

   clj -Srepro -Sdeps '{:deps {expound/expound {:mvn/version "0.9.0"} org.clojure/test.check {:mvn/version "0.9.0"} org.clojure/clojurescript {:mvn/version "1.10.520"}}}' -e "(require '[expound.alpha :as expound]) (set! clojure.spec.alpha/*explain-out* expound.alpha/printer)" -m cljs.main -re node

   Now you will get Expound errors during macro-expansion:

   ClojureScript 1.10.520
   cljs.user=> (require '[clojure.core.specs.alpha])
   nil
   cljs.user=> (let [x])
   Execution error - invalid arguments to cljs.analyzer/do-macroexpand-check at (analyzer.cljc:3772).
