Polyglot example

• Install the language engines for R, ruby and python with the following commands:

gu install R
gu install ruby
gu install python

NOTE: if you use the docker image as described below you don't have to install them as they are already installed.

• Navigate to the polyglot directory
• Run javac HelloPolyglot.java to compile HelloPolyglot.java with GraalVM.
• Run java HelloPolyglot to run the application on GraalVM.

GraalVM Workshop docker image

A fully configured GraalVM Docker image has been made for this workshop to play around with.

you can run it with the following command:

docker run -it --rm --name graalvm -v $(pwd):/project -v ${HOME}/.m2:/root/.m2 ivonet/graalvm:1.0.0-rc14

• Runs the GraalVM image in interactive terminal mode
• Names it graalvm
• Mounts the current folder into the /project folder of the container (which is the working dir)
• Mounts the maven config dir into the container maven config dir
• Removes itself (--rm) when closed (remove this if you want to save the state / container)

The command can of course be adjusted to your needs :-)
