来自Java并且熟悉Eclipse，我喜欢逆时针(用于Clojure开发的Eclipse插件)提供的功能:http://doc.ccw-ide.org/documentation.html#_debug_clojure_code

从2016年开始，你可以使用Debux，这是Clojure/Script的一个简单调试库，可以与repl以及浏览器的控制台一起工作。您可以在代码中添加dbg (debug)或clog (console.log)宏，并轻松观察各个函数的结果，等等，打印到您的REPL和/或控制台。

来自项目的Readme:

Basic usage This is a simple example. The macro dbg prints an original form and pretty-prints the evaluated value on the REPL window. Then it returns the value without interfering with the code execution. If you wrap the code with dbg like this, (* 2 (dbg (+ 10 20))) ; => 60 the following will be printed in the REPL window. REPL output: dbg: (+ 10 20) => 30 Nested dbg The dbg macro can be nested. (dbg (* 2 (dbg (+ 10 20)))) ; => 60 REPL output: `dbg: (+ 10 20) => 30` dbg: (* 2 (dbg (+ 10 20))) => 60

你也可以插入代码，使用Alex Osborne的debug-repl将自己放入一个带有所有本地绑定的REPL:

(defmacro local-bindings
  "Produces a map of the names of local bindings to their values."
  []
  (let [symbols (map key @clojure.lang.Compiler/LOCAL_ENV)]
    (zipmap (map (fn [sym] `(quote ~sym)) symbols) symbols)))

(declare *locals*)
(defn eval-with-locals
  "Evals a form with given locals. The locals should be a map of symbols to
values."
  [locals form]
  (binding [*locals* locals]
    (eval
     `(let ~(vec (mapcat #(list % `(*locals* '~%)) (keys locals)))
        ~form))))

(defmacro debug-repl
  "Starts a REPL with the local bindings available."
  []
  `(clojure.main/repl
    :prompt #(print "dr => ")
    :eval (partial eval-with-locals (local-bindings))))

然后要使用它，将它插入到你想要repl开始的地方:

(defn my-function [a b c]
  (let [d (some-calc)]
    (debug-repl)))

我把这个插入我的用户。clj，所以在所有REPL会话中都可用。

如果你使用emacs/slime/swank，那么在REPL试试这个:

(defn factorial [n]
        (cond (< n 2) n
              (= n 23) (swank.core/break)
              :else (* n (factorial (dec n)))))

(factorial 30)

它不像在LISP下那样为您提供完整的堆栈跟踪，但它很适合进行探查 周围。

这是优秀的工作:

正如上面的评论所提到的。

下面是一个调试复杂let表单的宏:

(defmacro def+
  "def with binding (def+ [{:keys [a b d]} {:a 1 :b 2 :d 3}])"
  [bindings]
  (let [let-expr (macroexpand `(let ~bindings))
        vars (filter #(not (.contains (str %) "__"))
               (map first (partition 2 (second let-expr))))
        def-vars (map (fn [v] `(def ~v ~v)) vars)]
    (concat let-expr def-vars)))

.．.以及一篇解释其用途的文章。

还有dotrace，它允许您查看所选函数的输入和输出。

(use 'clojure.contrib.trace)
(defn fib[n] (if (< n 2) n (+ (fib (- n 1)) (fib (- n 2)))))
(dotrace [fib] (fib 3))

产生输出:

TRACE t4425: (fib 3)
TRACE t4426: |    (fib 2)
TRACE t4427: |    |    (fib 1)
TRACE t4427: |    |    => 1
TRACE t4428: |    |    (fib 0)
TRACE t4428: |    |    => 0
TRACE t4426: |    => 1
TRACE t4429: |    (fib 1)
TRACE t4429: |    => 1
TRACE t4425: => 2
2

在Clojure 1.4中，dotrace已经移动了:

你需要依赖:

[org.clojure/tools.trace "0.7.9"]
(require 'clojure.tools.trace)

您需要将^:dynamic添加到函数定义中

(defn ^:dynamic fib[n] (if (< n 2) n (+ (fib (- n 1)) (fib (- n 2)))))

那鲍勃又成了你的叔叔了

(clojure.tools.trace/dotrace [fib] (fib 3))

TRACE t4328: (fib 3)
TRACE t4329: | (fib 2)
TRACE t4330: | | (fib 1)
TRACE t4330: | | => 1
TRACE t4331: | | (fib 0)
TRACE t4331: | | => 0
TRACE t4329: | => 1
TRACE t4332: | (fib 1)
TRACE t4332: | => 1
TRACE t4328: => 2
