Eclipse 3.4: state of affairs

Many technologies are now the reference

OSGi, Equinox : component/plug-in model

RCP : rich client

EMF : modeling

A very active Open Source community

Eclipse Foundation

e4: WHY?

Entry fee is too high for

plug-in developers

potential contributors

APIs are

hard to find

(sometimes) not documented well

(sometimes) redundant

Bad separation of concerns

The Eclipse platform is too closed

The e4 Plan

What e4 needs to address:

new UI directions

bring modeling to the IDE

improve p2 integration

keep on leveraging andpromoting OSGi andEquinox

Eclipse 4.0 SDK... built one4!

Developers eat their owndog's food!

The e4 Plan - UI

(More) separation of appearance from content

Scripting

Styling (CSS-like)

Declarative UI

Other (better?) look&feel

forget some IDE preconception

Web

8/14/2019 e4 web

17/29


lRightReserved

The e4 Plan - Modeling

Expose a DOM of the Workbench

secret dream: implement a CSS-like presentation layer

Leverage the EMF infrastructure?

code generation (with minimal footprint)

notifications

serialization

...

The e4 Plan - p2

Replace this good old Update Manager

Two kinds ofrepositories

artifacts

metadata

Much better management of

dependencies

profiles

installation/removal

8/14/2019 e4 web

19/29


The e4 Plan - RT

Eclipse is often seen as tools, but is in fact a platform

One platform to rule them all!

Consistent programming

Common component model set of basic services

...many implementations

Equinox

ECF

eRCPRAP

Riena

etc.

RAP

Bring the Workbench to the Web

Server-side: Equinox

Client-side: qooxdoo

The RAP widget toolkit is based on SWT

8/14/2019 e4 web

22/29


RAP vs. RCP

RCP RAP

Plugin Model OSGi

SWT

JFace

Workbench Web Workbench

OSGi on the server

(inside a webapp)

Widget

Toolkit

WWW Widget

Toolkit (W4T)

Model View

Controller

JFace (adapted, as

standard JFace has

references to SWT)

UI

Framework

8/14/2019 e4 web

From SWT 3.x to SWT 4

SWT

The Eclipse graphical toolkit

Efficient, portable, native

Native code, Java interface

Supported by many platforms Desktop : Windows, Macintosh, Linux, Solaris

Embedded : Windows Mobile, Nokia phones, ...

Web : RAP

8/14/2019 e4 web

24/29


Future of SWT

Be more webish

Because there are more and more web applications

Choose one (many?) target platform

RAP 2 qooxdoo, Dojo, ...

Flex ActionScript

Silverlight

.Net

8/14/2019 e4 web

25/29


Rethink the Application Model

Think in terms ofservices

Which service do I need? and the UI should not be seen as a service, thus not part of the AM

more than Is this the A, B, or whatever plug-in that will

help me to do such or such thing? strongly described

automatically generated documentation

The Twenty Things basic essential services Eclipse must address

SelectionService, Adapters, Undo/Redo, Menus, ...

Ensure backward compatibility

Strong business need for backward compatibility

1000+ plug-ins in EPIC

BUT e4 is the chance to clean-up fuzzy APIs

Eclipse 3.x experience

compatibilityplug-in fragments

Timeline

May 22-23, 2008: e4 Summit in Ottawa

Project proposal to come

Developments already started

e4-incubatorin the Eclipse CVS

Try to sync-up with 3.x changes when possible

Release in 2010!
