Graal VM 0.28 changed a command to run Graal VM Shell

In 0.26 there was graalvm command in bin directory.

$ graalvm --shell
GraalVM MultiLanguage Shell 0.23
Copyright (c) 2013-7, Oracle and/or its affiliates
  JS version 0.9
  R version 0.1
  Ruby version 2.3.3
Usage: 
  Use Ctrl+L to switch language and Ctrl+D to exit.
  Enter -usage to get a list of available commands.
Ruby> 1 + 2
3

In 0.28 graalvm command has gone. Instead of it, we can use polyglot command.

$ polyglot --shell
GraalVM MultiLanguage Shell 0.28.2

  JavaScript version 0.9
  Ruby version 2.3.3
Usage: 
  Use Ctrl+L to switch language and Ctrl+D to exit.
  Enter -usage to get a list of available commands.

It's ok, but I can't use R in this shell. Why?

Participated in JavaOne 2017

I participated in JavaOne 2017 in San Francisco! This was the third time. I really enjoyed JavaOne. This Photo is with Japanese JUG members, Steven, Sebastian and Yolande.

I am in the middle in front of Steven.

Did you watch Developer Keynote? It was play like the movie Matrix. My friends take roles in play.

I heard sessions about Graal and OpenJ9. They are very interesting to me.

I'm a JUG leader, so I attend some parties, such as JCP party and APPDEV APPETIZERS AND DRINKS (I love beer of Thirsty Bear Brewing).

Next year I wish I could see you and talk with you!
