An ipython kernel for java 9

java9_kernel (forked for working with OpenJDK)

An ipython kernel for java 9 openjdk.

Expectation Setting

This is an experimental ipython kernel written with an experimental repl written for a unreleased java version. Don't expect this to be production ready.

Requirements

Install [java9-openjdk]

This kernel expects two environment variables defined, which can be set in the kernel.json (described below):

JAVA_9_HOME - like JAVA_HOME but pointing to a java 9 environment

Installing the kernel

Assuming you have cloned the repo and got all the requirements above setup

edit kernel.json replacing PATH_TO_javakernel to the location of the javakernel directory

mkdir ~/.ipython/kernels/java/

cp <location of your edited kernel.json> ~/.ipython/kernels/java/

For example a kernel.json might look like this:

{
 "argv": ["python3", "<javakernel_path>",
          "-f", "{connection_file}"],
 "display_name": "Java 9",
 "language": "java",
 "env" : {
     "JAVA_9_HOME": "<java_path>",
     }
 }       

If all worked you should be able to run the kernel:

[1] String a = "test"

|  Added variable a of type String with initial value "test"
