Goodbye Helma, hello Ringo!

If you have followed the Helma project in some closeness, you probably noticed that active development on Helma 1, which already had slowed down since the inception of Helma NG, has pretty much come to a standstill since the 1.7 release. After 12 years it just doesn't feel like a good idea to add new features to an already mature code base. Hence, Helma has now entered maintainance mode. We will still provide occasional bug fixes when necessary, but there will be no more major releases.

Of course Helma has a worthy successor in RingoJS, the project that started out as Helma NG. If you're starting out with a server-side JS project and like Helma be sure to give Ringo a try. Ringo is not as tightly integrated out of the box as Helma, but that should turn out to be one of its advantages: Due to its more open, CommonJS and command line oriented design, Ringo already has an number of packages that let you easily do things that were hard or impossible to do with Helma.

Whichever tool you choose, JavaScript on the Java VM will continue and improve to be a great and reliable platform for writing server-side applications for the years to come!

Helma NG

Please note: Helma NG has been relaunched as RingoJS. See the announcement on the mailing list for more information.

Helma NG stands for Helma Next Generation and is a version of Helma built from the ground up. The main differences between Helma 1 and Helma NG are that Helma NG has a much smaller and leaner Java core (mostly just runtime, shell, and the module and resource loader), and that Helma NG aims to provide full CommonJS interoperability.

This is a wiki space dedicated to Helma NG. Feel free to create new pages or edit existing ones.

Overview

Helma NG consists of several components that can be used together or alone:

A compact JavaScript runtime environment based on Mozilla Rhino. It adds to Rhino a reloading module system that is compatible to the CommonJS Securable Module proposal.
An interactive shell with support for autocompletion and history.
A module library implemented in JavaScript, covering basic functionality such as extensions to the built-in objects, file I/O, logging, persistence, unit testing, client and server side HTTP support and web framework.
