在ns宏中使用：require和：use的最惯用方式是什么

Question

What's the most idiomatic way to use the :require and :use in the ns macro?

(ns app.core
  (:require [clojure.tools.logging :as log]
            [clojure.java.io :as io]
            [clojure.edn])
  (:use [compojure.core]
        [postal.core]
        [ring.adapter.jetty]
        [ring.middleware.multipart-params]))

or

(ns app.core
  (:require [clojure.tools.logging :as log])
  (:require [clojure.java.io :as io])
  (:require clojure.edn)
  (:use compojure.core)
  (:use postal.core)
  (:use ring.adapter.jetty)
  (:use ring.middleware.multipart-params))

or somehow else?

Is there any common guidelines or best practices?

Answer 1

Your first example is more idiomatic. However, the use of use or :use is discouraged, so the most idiomatic way would be this:

(ns app.core
  (:require [clojure.edn]
            [clojure.java.io :as io]
            [clojure.tools.logging :as log]
            [compojure.core :refer :all]
            [postal.core :refer :all]
            [ring.adapter.jetty :refer :all]
            [ring.middleware.multipart-params :refer :all]))
