Resolves namespace-qualified sym per 'resolve'. If initial resolve fails, attempts to require sym's namespace and retries.

;; Resolve a qualified symbol (requiring-resolve 'clojure.java.shell/sh) ;; Resolve and evaluate ((requiring-resolve 'some-ns/some-fn)) ;; In deps.edn, replace all spaces with the "Corfield" comma, ;) ((requiring-resolve,'clojure.java.shell/sh))

(defn debug? [] (= (env :debug?) "true")) ;; If you need to do conditional requires such as the one below: (if (debug?) (do (require '[nrepl.cmdline :refer [-main] :rename {-main -nrepl-main}]) (resolve 'nrepl.cmdline)) (declare -nrepl-main)) (defn -main [& args] (when (debug?) (future (apply -nrepl-main args)))) ;; This is strictly better! (defn -main [& args] (when (debug?) ;; Swap to require and resolve in one step! (future (apply (requiring-resolve 'nrepl.cmdline/-main) args))))
