Helios is the simultaneous release of 39 Eclipse projects. In terms of statistics, the Helios release includes 33 million lines of code developed by about 500 Eclipse.org committers from 44 companies. The important thing to remember about Helios and Eclipse simultaneous releases in general is that even though it's a simultaneous release, it doesn't mean these projects are unified. Each project is a separate open source project within Eclipse.org, operating with its own project leadership, its own committers and its own development plan. The simultaneous-release concept is designed to provide a transparent and predictable development cycle.

Get Helios

There are two main ways to get Helios-related projects. The first — and recommended — way is to just grab a package relevant to you. The other way is via the Helios software repository at Eclipse.org.

Go to the Eclipse Helios Packages site, which contains 12 pre-bundled versions of Helios projects specific to your needs.

Helios repository

To get Helios using a software repository, download the Eclipse V3.6 SDK. Then you can launch Eclipse and access the software-update mechanism via Help > Install New Software (see Figure 2). Enter the proper Helios repository information, if it isn't already available. Once you are connected, you should see the list of available projects that are part of the Helios release. It's as simple as that. Once you're connected, you can simply choose what features to install into your Eclipse.

Eclipse Marketplace

It's important to mention that the Eclipse Marketplace was launched as part of the Eclipse Helios release. It offers the Eclipse community a convenient portal that helps folks find open source and commercial Eclipse-related offerings. If you downloaded Helios via a package, you'll have access to the Eclipse Marketplace client via Help > Marketplace Client that allows you to easily browse the marketplace offerings and install them into Eclipse (see Figure 3).

Project showcase

Linux tools

"The Eclipse Linux Tools project is pleased to be a part of the Helios simultaneous release," said Andrew Overholt, project lead. "Our project aims to provide tools for Linux® C/C++ developers, building on top of the rich Eclipse toolset, including the Platform, the CDT, BIRT, and GEF.  We provide Eclipse plug-ins to integrate with native development tools, such as the GNU Autotools, LTTng, Valgrind, GCov, OProfile, RPM, GProf, and SystemTap. Our main goal is to provide a full-featured C and C++ IDE for Linux developers."

Overholt also said, "Helios includes our 0.6 release, which features improvements to many of our components. Our LTTng integration features a new histogram view to help with visualizing trace files and our GProf plug-ins now allow for easy viewing with BIRT-driven charts. Speaking only of 0.6 does not do justice to the work that has gone into our previous releases that have never been a part of the Eclipse simultaneous release:

  • GNU Autotools integration with the CDT allowing for the many existing projects that use the GNU Autotools to build from within Eclipse
  • a C/C++ call graph utility that is driven by SystemTap and visualized with Zest from GEF
  • an RPM .spec editor with rpmlint integration
  • display of GProf profiling data
  • GCov code coverage display and annotation
  • a framework for integrating native profiling tools with the CDT
  • simple launching and visualization of Valgrind memory usage analysis tools for CDT projects
  • single-click profiling with OProfile and integration with the CDT
  • ChangeLog management tools which integrate with various version control providers
  • plugins bridging the CDT's hover help functionality with various open source API documentation formats; called libhover

"On top of that, a lot of bug fixing has also gone into our 0.6 release."

And Overholt said, "The Linux Tools project also aims to increase the amount of Eclipse technology available in Linux distributions. We are working towards this goal by providing a build harness of the Eclipse SDK that is easy to consume for Linux distributions and already have a number of distribution consumers."

"Xtext is a language development framework that allows to easily develop your own domain-specific or full-fledged programming languages and corresponding Eclipse-based IDE support," said Sven Efftinge, Xtext committer. "Based on a grammar language and a set of modern APIs, one can describe the syntax and semantics of the language. Xtext provides a rich-featured and highly configurable IDE, including validation, code completion, an outline, formatting, syntax coloring, code-generation stubs, etc. In the Helios release, Xtext graduated to Version 1.0. It now features namespace-based scoping, builder infrastructure, validation and linking based on dirty state, quick fixes, linking to Java elements, enhanced serialization support, and much more. This makes Xtext amenable not only for domain-specific languages but also for full-fledged programming languages."

Rich Ajax Platform (RAP)

RAP makes it easier to single-source desktop and web applications with Eclipse RCP and RAP.

RAP committer Benjamin Muskalla said, "The Rich Ajax Platform has grown into a mature platform for server-side OSGi development of rich Internet applications. As part of the Helios release, it not only offers many new state-of-the-art features like drag and drop, a GraphicsContext and rich theming capabilities but in addition tight integration with other Eclipse projects like EMF and Riena. Using RAP for single-sourcing existing RCP applications enjoys enormous popularity withtin the Eclipse community."

"Sequoyah was chartered in December 2009 to provide a project for mobile tools developers, regardless of which language or mobile platforms they use," said Eric Cloninger, project lead. "Our committers come from Motorola, Nokia, and Wind River. Sequoyah also has strong participation from RIM and the Symbian Foundation.

"We began the project by moving several narrowly focused subprojects from DSDP and took responsibility for the Pulsar package. For Helios, we've added new components and we will graduate as a mature project with this release. The future of Sequoyah is promising as we have several new proposals under way for supporting web applications and Android native development."

PHP Development Tools (PDT)

Project lead Roy Ganor said, "Summarizing a great year for both the Eclipse and PHP communities, the Eclipse PDT project provides even more source editing features for the PHP developers, such as new template content assist and advanced syntax coloring. Our focus on quality has proven to be immensely successful. With over 400 issues fixed and over 50 enhancements contributed by the community, PDT is more stable than ever."

C/C++ Development Tools (CDT)

"The CDT project is offering improved debug support for the Helios release," said Doug Schaefer, CDT project lead. "First off, the DSF/GDB debug interface reached sufficient parity with existing CDI/GDB interface to warrant switch in default launch configuration type. Furthermore, a new Eclipse C/C++ Debugger (EDC) is introduced as optional component that provides direct debugger interface to OS APIs for Windows and Linux. On top of that, we introduced the new Codan static analysis framework as optional component to provide semantic error reports ahead of compile time. Also, support for C++0x is progressing well as matching support provided by gcc 4.3+."

Mik Kersten, project lead, said, "Since last year's Galileo release, Mylyn's APIs, features and integrations have grown substantially. Popular features such as Mylyn's Connector Discovery are now reusable. We've created scheduled presentation that will help the growing number of Mylyn users that manage very large task lists. C/C++ developers now get one-click multitasking and workspace focusing out of the box, with support for CDT. But what's most exciting is how much the Mylyn ecosystem has grown during the Helios release. As of June, the majority of leading Agile and ALM tools provide Mylyn connectors, helping an increasingly large portion of the developer community get the productivity benefits of the task-focused interface."

Friend of Helios and Eclipse

There are many people that use Eclipse out there, from developers to just users who sometimes want to give back to the Eclipse community in some fashion. The Friends of Eclipse program allows you to contribute back to the Eclipse community. To celebrate the upcoming Helios simultaneous release, The Eclipse Foundation wants to recruit 360 new Friends of Eclipse. For a $35 contribution, you can become a Friend of Eclipse and get early access to the Helios release, direct from the download server at the Eclipse Foundation. Your contribution will also help support the Eclipse community in a variety of ways:

  • Providing more bandwith for users and developers
  • Purchasing additional servers to host Eclipse projects
  • Sending students to Eclipse conferences
  • Sponsoring Eclipse community events

Helios review contest

The Eclipse Foundation wants to hear what you think of the Eclipse Helios projects being shipped as part of Helios. The Eclipse Foundation is hosting a review contest so if you write a review about Helios you'll be entered to win some prizes. All qualified reviews get a Helios T-shirt. Since Eclipse is a global community, feel free to write or record your review in any language that you're comfortable with.


What's next after Helios?

The Eclipse community recently voted that the name of the next simultaneous release will be Indigo. See you in June 2011 for Indigo.

The goal of this article was to take you through the Helios simultaneous release and showcase some of the projects that are part of the release. I gave you a tour of the Helios projects with some information from Eclipse project leaders.

So what are you waiting for? Go grab Eclipse Helios and give it a try.
