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。

javaのバージョン確認

Java HotSpot(TM) 64-Bit Server VM (build 20.65-b04-466.1, mixed mode)

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。

activatorコマンドの確認

[dela@MacBook-Air dela] activator -help
Usage: activator <command> [options]

  Command:
  ui                 Start the Activator UI
  new [name] [template-id]  Create a new project with [name] using template [template-id]
  list-templates     Print all available template names
  -h | -help         Print this message

  Options:
  -v | -verbose      Make this runner chattier
  -d | -debug        Set sbt log level to debug
  -mem <integer>     Set memory options (default: , which is -Xms1024m -Xmx1024m -XX:MetaspaceSize=64m -XX:MaxMetaspaceSize=256m)
  -jvm-debug <port>  Turn on JVM debugging, open at the given port.

  # java version (default: java from PATH, currently java version "1.8.0_65")
  -java-home <path>  Alternate JAVA_HOME

  # jvm options and output control
  -Dkey=val          Pass -Dkey=val directly to the java runtime
  -J-X               Pass option -X directly to the java runtime
                     (-J is stripped)

  # environment variables (read from context)
  JAVA_OPTS          Environment variable, if unset uses ""
  SBT_OPTS           Environment variable, if unset uses ""
  ACTIVATOR_OPTS     Environment variable, if unset uses ""

In the case of duplicated or conflicting options, the order above
shows precedence: environment variables lowest, command line options highest.

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

[dela@MacBook-Air develop] activator new my-first-app play-scala
[dela@MacBook-Air develop] cd my-first-app/
[dela@MacBook-Air my-first-app] activator
#省略
[error] java.lang.UnsupportedClassVersionError: org/webjars/WebJarExtractor$Cache : Unsupported major.minor version 51.0

jdkを更新。使おうとしてるバージョンに合わせる。
Java SE - Downloads | Oracle Technology Network | Oracle
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

脇のメニューから大体できること想像がつく。サーバーのコードをブラウザから変更できそう。
使ってみないと判断できないけど、思想は進んでる。
