再び Clojure

JDK 10 + Clojure 1.9.0 にしてみました。

leiningen は使わなくてもいいみたいです。まだよくわかっていません。

$ java -version
java version "10" 2018-03-20
Java(TM) SE Runtime Environment 18.3 (build 10+46)
Java HotSpot(TM) 64-Bit Server VM 18.3 (build 10+46, mixed mode)

$ brew install clojure

$ clj
Clojure 1.9.0
user=> (+ 2 3)
5
user=> (println "hello")
hello
nil

また気が向いたらあれこれ遊んでみます。

Clojure始めました

最近ちょっと勉強し始めています。

JDK 9 ではうまく動かなかったので8に入れ直し、brew install leiningen から。
