RingoJS

RingoJS is a JavaScript runtime written in Java based on Mozilla Rhino.

It adds a number of features to Rhino that make it suitable for real-world, large-scale application development:

  • A fast, auto-reloading, and CommonJS-compliant module loader.
  • A rich set of modules covering I/O, logging, persistence, development tools and much more.
  • Scalable HTTP server based on the Jetty project.
  • Support for CommonJS packages to install or write additional software components.

For more information, visit the RingoJS web site: http://ringojs.org/

Building RingoJS

Ringo requires a recent version of Java. It uses Apache Ant as build tool and Ivy for managing dependencies.

If you have these installed, building Ringo is straightforward:

Check out Ringo using Git:

git clone git://github.com/ringo/ringojs.git

Change to the ringojs directory and run the ant update task to fetch dependencies:

ant update

Then run the jar task to compile the code and build the jar file:

ant jar

Run the docs task to build the documentation:

ant docs

Running RingoJS

It is recommended but not strictly required to add the ringojs bin directory to your PATH environment variable. If you don't you'll have to type the full path to the bin/ringo command in the examples below.

To start the Ringo shell, just run the ringo command without any arguments:

ringo

To run a script simply pass it to ringo on the command line. For example, to run the Ringo test suite:

ringo test/all.js

Use the ringo-admin command to create a new web application or install packages. To create a blank Ringo web app:

ringo-admin create [appdir]

To install a package from a zip URL:

ringo-admin install [packageurl]
