问题描述
我想根据我的代码是从REPL运行还是运行已编译的jar,以不同的方式格式化日志.
I would like to format my logs differently depending on whether my code is being run from a REPL or if I'm running the compiled jar.
有没有简单的方法可以做到这一点?我在想也许雷宁根在运行REPL时会留下痕迹.
Is there any simple way to do this? I was thinking maybe Leiningen leaves a trace somewhere when running the REPL.
推荐答案
(defn current-stack-trace []
(.getStackTrace (Thread/currentThread)))
(defn is-repl-stack-element [stack-element]
(and (= "clojure.main$repl" (.getClassName stack-element))
(= "doInvoke" (.getMethodName stack-element))))
(defn is-in-repl []
(some is-repl-stack-element (current-stack-trace)))
(defn my-log [msg]
(if (is-in-repl)
(prn (str "RUNNING IN REPL : " msg))
(prn msg)))
