Interactive Console

Running the jep script

The setup.py script will provide a jep or jep.bat script to make launching Jep easier. The jep script is very similar to running python from a terminal/command line. If run with an argument of a file path, it will run the script at that path. If run with no arguments, it will provide an interactive console that combines the Python language with access to Java classes on the classpath.

    $ jep
    >>> from java.lang import System
    >>> System.out.println('hello, world')
    hello, world
    >>>

readline support

The jep script will attempt to use readline to remember previous commands. If readline is supported, you can press the up arrow key ↑ to cycle through commands from a previous jep session. If readline is not supported, the script will print an informative message and you can continue on without this functionality.

For Windows, you will need pyreadline to enable the ability to remember commands from a previous jep session. Make sure you get the latest pyreadline, preferably from their master branch on github, and not from the pypi website (and therefore not from pip).
