Eclipse Demo Camp 2010 - Eclipse e4 – The Status and the Future

Eclipse e4 – The Status and the Future Presentation by Tonny Madsen at Eclipse Demo Camp in Copenhagen 1. December 2010

The Eclipse Story
1994: IBM develops VisualAge for Smalltalk – programmed in Smalltalk
1995: Java is released to a select group
1996: IBM develops VisualAge for Java – still programmed in Smalltalk
November 1998: OTI (Object Technology International – part of IBM) is commissioned to develop new development platform for Java
First known as VisualAge Micro Edition (VAME) and later Eclipse
7. November 2001: Eclipse 2.0 made Open Source
25. June 2004: Eclipse 3.0 released introducing Eclipse RCP
Framework make-over introducing OSGi
2009: Eclipse 3.5 released – known as Galileo
27. June 2010: Eclipse 3.6 will be released
Also known as Helios
End of July, 2010: Eclipse SDK 4.0 Early Adopter Release
First release of e4 technology
June 2011: Eclipse 3.7 will be released
June 2011: Eclipse 4.1 will be released
June 2012: Eclipse 4.x will be released

The e4 History
5. Marts 2008: Later night at EclipseCon ’08
SWT Browser Edition
Eclipse IDE in a Browser
Separation of WB Model and View
Scripting
20. May 2008: Mail to e4-dev „A radical approach to explore new paths for e4“
Platform designed from Scratch
Based upon an EMF-Application-Model
No statics, no singletons, usage of Dependency Injection
Based on OSGi-Services
20. November 2009: 1.0M2 released

SWT Browser Edition
Technology worked really well
But not applicable without rewriting Java
We’d rather rewrite with HTML5, JavaScript, CSS

Why e4
Simplify the Eclipse programming model
This will reduce development and maintenance costs and enable a larger developer community to leverage the platform in their own Eclipse-based applications
Enable the platform for use on emerging web-based runtime technologies
This will ensure the platform remains a compelling and viable application framework in a rapidly changing web technology landscape, and it will allow e4-based applications to leverage web technologies, while remaining insulated from specific technology choices that may quickly become obsolete
Broaden participation in development of the platform
This reduces the risks associated with building on a platform largely funded from a single source. Having a large and diverse group of commercial backers, will ensure the platform remains vibrant and viable over the long term

Main Technical Differences between Eclipse 3.x and e4
Application Model in EMF
Complete live model for the application – changes are reflected immediately in the application
Rendering the Application
Maps the model to the UI
Allows for a completely new look and feel without touching the internals
Allows support for different widget sets – even Adobe Flash or Microsoft Silverlight
Context
Contains the context/environment for all contributions
Brokers interaction with the framework: service lookup, service registration
Dependency Injection
Allows for POJOs for all contributions

Application Model

Code for Parts
The code that provides the “parts” of the application is ordinary POJO
No special inheritance – e.g. IViewPart or IWizardPage
Services provided via Dependency Injection
public class Preview { public Preview(Composite parent, Realm workspace) { // Create UI ... } @In public void setSelection(final IFile input) { // React on Selection Changes } }

Open Social Gadgets
What are OpenSocialGadgets
Gadgets are web-based software components based on HTML, CSS, and JavaScript.
Open Eclipse for a new set of devlopers
Examples
