Clojure Example2 Destructuring

clojure

(ns clojure.examples.hello
   (:gen-class))
(defn Example []
   (def my-vector [1 2 3 4])
   (let [[a b c d e] my-vector]
   (println a b c d e)))
(Example)

Clojure Destructuring

clojure

(ns clojure.examples.example
   (:gen-class))
(defn Example []
   (def my-vector [1 2 3 4])
   (let [[a b c d] my-vector]
   (println a b c d)))
(Example)

Clojure Predicates not-any

clojure

(ns clojure.examples.example
   (:gen-class))
(defn Example []
   (println (not-any? even? '(2 4 6))))
(Example)

Clojure Predicates some

clojure

(ns clojure.examples.example
   (:gen-class))
(defn Example []
   (println (some even? '(1 2 3 4))))
(Example)

Clojure Predicates every

clojure

(ns clojure.examples.example
   (:gen-class))
(defn Example []
   (println (every? even? '(2 4 6)))
   (println (every? odd? '(2 4 6))))
(Example)

Clojure Predicates every-pred

clojure

(ns clojure.examples.example
   (:gen-class))
(defn Example []
   (println ((every-pred number? even?) 2 4 6))
   (println ((every-pred number? odd?) 2 4 6)))
(Example)

Clojure Predicates

clojure

(ns clojure.examples.example
   (:gen-class))

;; This program displays Hello World
(defn Example []
   (def x (even? 0))
   (println x)
   
   (def x (neg? 2))
   (println x)
   
   (def x (odd? 3))
   (println x)
   
   (def x (pos? 3))
   (println x))
(Example)

Clojure Regular Expressions replace-first

clojure

(ns clojure.examples.example
   (:gen-class))

;; This program displays Hello World
(defn Example []
   (def pat (re-pattern "\\d+"))
   (def newstr1 (clojure.string/replace "abc123de123" pat "789"))
   (def newstr2 (clojure.string/replace-first "abc123de123" pat "789"))
   (println newstr1)
   (println newstr2))
(Example)

Clojure Regular Expressions replace

clojure

(ns clojure.examples.example
   (:gen-class))

;; This program displays Hello World
(defn Example []
   (def pat (re-pattern "\\d+"))
   (def newstr (clojure.string/replace "abc123de" pat "789"))
   (println newstr))
(Example)

Clojure re-find Regular Expressions

clojure

(ns clojure.examples.example
   (:gen-class))

;; This program displays Hello World
(defn Example []
   (def pat (re-pattern "\\d+"))
   (println (re-find pat "abc123de")))
(Example)
