Lars Vogel gives a presentation on the state of Eclipse. He discusses his background with Linux and Eclipse. The presentation covers the Eclipse ecosystem, including the Eclipse Foundation and projects. Vogel describes how Eclipse is highly modular and extensible via plugins. He discusses Eclipse 4.0 and the move to a more flexible and model-driven architecture. In conclusion, Vogel recommends resources for learning more about Eclipse plugin and RCP development.

1. Eclipse – State of the union- with a little, little focus on LinuxLars Vogelhttp://www.vogella.dehttp://www.twitter.com/vogella

2. Lars VogelWorking for SAP AG as a product managerPrivately contributing to in the Java and Eclipse ecosystemPublish programming tutorials on http://www.vogella.deWho am I ?

3. I used to use Linux / Unix quite a bit but this a while agoEmacs and KDE rules!My server for http://www.vogella.de runs on Ubuntu I still think that the command line is coolMe and Linux

4. Todays talk will be about Java and programming for and based on Eclipse

5. Eclipse is written in Javain little pieces (plugins)

6. Mini-Agenda The Eclipse EcosystemEclipse and modularityEclipse Plugin and RCP developmentEclipse 4.0 / Eclipse e4

7. The Eclipse Ecosystem

8. Successful Open Source Projects

9. Unlike other (successful) OpenSource Projects Eclipse has no mascotThis is NOT the animal representing Eclipse

10. ImpactEclipse – History BookVery disruptive for the pay IDE Eclipse is a vendor independent Open Source ProjectNov. 2001 – Code released as Open Source, still lead by companiesFebr. 2004 – Eclipse Foundation created

11. ImpactEclipse – History BookStart of Eclipse as a platform, e.g. NASA starts using Eclipse for it‘s Mars missionMarket leader with a strong ecosystemRe-gain innovation speedJuni 2004 – Eclipse 3.0 based on OSGi and enables Eclipse RCP 2010 - Current Eclipse 3.5.2 (aka Ganymede)06.2010 Release of Eclipse 3.607.2010 Planned first release of Eclipse 4.0

12. Eclipse Foundation The Eclipse Foundation is a not-for-profit, member supported corporation that hosts the Eclipse projects and helps cultivate both an open source community and an ecosystem of complementary products and services.

13. Eclipse Foundation does not pay developersMember companies and private persons develop the code

14. STRATEGIC MEMBERS

15. ALL MEMBERS

16. Members, there are 160 as of today.14 Strategic3 Enterprise74 Solutions69 Associate

17. Eclipse ProjectsOver 100 Eclipse projectsOriginally very IDE focused but start getting divershttp://www.eclipse.org/projects/listofprojects.php

18. CDT C and C++ developmentJDT Java Development Toolsand much, much more…EgitGit with JavaPHPRuntimeEquinox (OSGi)RAP…WebtoolsPlatformJSF JPAWebservicesHTMLJavaScriptPDE Plugin Development Tools

19. Eclipse Download StatisticsDownloads bundle several projects

20. All Eclipse.org source code is released under the Eclipse Public License (EPL)

21. EPL is business friendlyDo what you want with the codeModification of the original code must be contributed back NOT viral like the GPL which companies like

22. 22Eclipse & third partiesGoogleGWTGoogle App EngineAndroid Dev toolsZENDPHP Studio IBMWebspereJazzAnd many more

23. The Eclipse communityVery welcomingEclipse forumsPlanetEclipse.org#eclipse at IRCSeems to be individual driven rather then company driven

24. I use Eclipse for Kernel Development* Quote complete made up by Lars

25. The modular architecture of Eclipse

26. Extensible Application - FirefoxPluginsThe Browser

27. In Eclipse everything is a plugin (except the core runtime)PluginPluginPluginPluginPluginRuntime

30. Each Plugin defines its available API

31. Each Plugin defines also its dependencies

32. Runtime (OSGi) makes sure the API contacts are fulfilled

33. Plugin and RCP Development

34. Your pluginsEclipse IDE

35. MANIFEST.MF – Defines OSGi bundleplugin.xml – Defines Eclipse extensions and extension pointsPDE (Plug-in Development Environement) provides editors for these files.Configuration files

36. Extensions Extension PointsProvide functionality to predefined slots (== extension points)Define places where others (== extensions) can provide functionality

37. Eclipse extensibility is a little bit like Emacs, you can add easily functionalityBut not in LISP

38. Thin layer upon the native GUI libraries JNI callsNot a lot of convenient functionalitySWT - Standard Widget ToolkitExample Gnome GTK+ for Linux*Screenshot from the Internet

39. Eclipse RCPHelpP2 Update………………Workbench…JFaceRuntime / Equinox (OSGi)SWT

40. JFaceUI toolkit that provides helper classes for developing UI featuresTables / TreeViewer / Dialogs / Can be based on modelsDatabindingWorkbench multi-window environment manages views, editors, perspectives JFace & Workbench

41. Viewer: Table / Treeviewer: Responsible for the UILabelProvider: How is the domain model representedModelProvider: Delivery the domain modelViewerSorter: Sorts values in the viewerViewerFilter: Filters valuesExample: JFace ViewerContentProvider – „Dao“ for viewer LabelProvider – Which data is represented howViewer – UI, shows data

42. The future of Eclipse – Problems & Solutions

43. All Eclipse code must be free of IP problemsIP Due Dilligence take a lot of time

44. Eclipse.org moving to git (jgit)Does Eclipse need a fork?Hope to enrich the ecosystem by making forking easy

45. Eclipse.org moving towards gitHope to enrich the ecosystem by making forking easy

46. Eclipse development got more and more complex over the years Eclipse 4.0 (aka e4)Developer Productivity

47. Eclipse 4.0

48. Eclipse e4 ScopeTargets developmentfor Eclipse (plugins) or based on Eclipse (Eclipse RCP).

49. Eclipse e4 TargetsMake Eclipse development more effective and the result more visual appealing.

50. Eclipse e4 – Building blocksDeclarative StylingRendering EngineModeled WorkbenchDependecy InjectionIEclipseContextCore Services

51. The Modeled Workbench

52. Eclipse 4.0 Application modelModels the Application (UI) and the behavior (commands)EMF basedModeled WorkbenchContent of the view not part of the e4 model

53. The e4 Workbench ModelEach application has it‘s live modelWorkbench window Menu with menu items Window Trim, e.g. toolbar with toolbar items Parts Sash ContainerPartsPart Stack (CTabFolder)PartsHandlersKey BindingsCommands

54. Model is FlexibleNo distinction between View and EditorPerspectives are optionalStack / Sash are optionalSeveral windows easily possibleFlexible Toolbars

55. Parts in Eclipse 4.0Plain Old Java Objects (POJO‘s)

56. InherianceHierachy of Views Parts before Eclipse 4.0ObjectEventManagerWorkbenchPartViewPartView

57. Model available at runtime

60. Renderer: flexible but complex

61. e4 CSS Styling

62. Eclipse3.X - IDE feelingEclipse e4 – CSS StylingExample from Kai ToedterSome elements cannot currently not be styled: Menu bar background

63. Table headers e4 supports theme switching during runtime

64. New Look & Feel for Eclipse e4 – SDK https://bugs.eclipse.org/bugs/show_bug.cgi?id=293481

65. The e4 Programming Model

66. Dependency InjectionInversion of control: The necessary functionality is injected into the classJava Class

67. Dependency Injection in e4JSR 330 compatible injection implementation@javax.inject.Inject – Field, Constructor and Method injection@javax.inject.Named – Specify a custom qualifier to context object (default is fully qualified classname of the injected type)e4 specific annotations, e.g. @Optional

68. Java Class Services are injected via the the e4 frameworkpublicclassListView { @Inject privateIEclipseContextcontext;@Inject private Loggerlogger; @Inject publicListView(Composite parent) {// ...

69. Eclipse and the webEclipse e4 targets to bring the Eclipse IDE closer to the webOne way would be to run Eclipse in the web, e.g. via Eclipse RAPAnother way would be to run the web inside Eclipse
