Scala Play activator on OSX
久しぶりにScala Play環境作ったらactivator というものが出てきたらしい。
"Typesafe Activator は activator ui と activator new という 2つのコマンドを追加するカスタム版の sbt だ。 つまり、activator は sbt のスーパーセットであると言える。"
始める sbt — Typesafe Activator (sbt を含む) のインストール
あ、はい。
以下を見ながらすすめた。

Scala 2.11.7はjdk1.6以上が必要。だから大丈夫な、はず。更新はあとでやろうと思う。
brew installで最新がインストールされる。

Scala Play アプリを新規作成して、activatorコンソールを起動する。

jdkを更新。使おうとしてるバージョンに合わせる。

ダウンロードして.zshrcのJAVA_HOMEを以下に変更
export JAVA_HOME=`/usr/libexec/java_home -v 1.8`
activatorコンソールを再起動する。

activator ui 使ってみた。
[dela@MacBook-Air my-first-app] activator ui

使ってみないと判断できないけど、思想は進んでる。
