Clojure动态关键字构建器函数返回意外结果

当我在repl中定义我的函数时,它按预期工作。当我将它放入命名空间(即我的应用程序)并重新加载repl时,我丢失了关键字上的namespace组件。我不确定我在这里缺少什么。

;; Repl
(defn repl-keyword-gen [k str] (keyword (name k) str))

(repl-keyword-gen :test "example")
;;=> :test/example


;; App - example.core
(defn app-no-sym-keyword-gen [str] (keyword "test" str))
(defn app-with-sym-keyword-gen [k str] (keyword (name k) str))

(app-no-sym-keyword-gen "example")
;;=> :test/example

(app-with-sym-keyword-gen :test "example")
;;=> :example   <----- Not sure about this one right here

非常感谢有关此关键字构建器返回不同结果的原因的见解/解释。

我认为您的环境可能存在问题。

我使用普通的lein run测试并获得了namespaced关键字:

(ns clj.core
  (:require 
    [tupelo.core :as t]
    [clj-time.core :as tm] 
  ))
(t/refer-tupelo)

;; App - example.core
(defn app-no-sym-keyword-gen    [str]   (keyword "test"   str))
(defn app-with-sym-keyword-gen  [k str] (keyword (name k) str))

(spyx (app-no-sym-keyword-gen "example"))

(spyx (app-with-sym-keyword-gen :test "example"))

(defn -main [& args]
  (println "-main"))

结果:

~/clj > lein run    
(app-no-sym-keyword-gen "example") => :test/example
(app-with-sym-keyword-gen :test "example") => :test/example
-main

要使(spyx ...)部分起作用,您需要在project.clj中使用它:

:dependencies [
  [tupelo "0.9.9"] 
  ...
