What is EMF Parsley?

Parsley provides an easy way to get a User Interface for EMF models:

  • with built-in UI components
  • easy customizations
  • with a powerful DSL

@EmfParsely www.eclipse.org/emf-parsley

Five good reasons

  • very lightweight and straightforward to use
  • out-of-the-box integrations with XMI, Teneo and CDO
  • dependency Injection (via Google Guice) instead of

Extension Point mechanism

  • Eclipse/JDT integrated DSL with a static type system
  • code-generation oriented (debuggable!) instead of a

reflective approach (no bad runtime surprises)

Parsley Components

Basic components can be used

  • ut of the box:
  • Tree
  • Table
  • Form
  • Tree Form
  • Table Form
  • Dialog

@EmfParsely www.eclipse.org/emf-parsley

… and more!

  • All components are provided as Java APIs
  • There are some views as reference implementation
  • Project Wizards with initial templates
  • Many examples to import
  • A rich Eclipse tooling

Typical EMF boilerplate code

@EmfParsely www.eclipse.org/emf-parsley

Tree code example

@Inject ViewerFactory viewerFactory; (...) treeViewer = new TreeViewer(parent); viewerFactory.initialize(treeViewer, element);

Instead in EMF Parsley the code is very simple

Table code example

@Inject ViewerFactory viewerFactory; (...) tableViewer = viewerFactory.createTableViewer(composite,SWT.BORDER | SWT.FULL_SELECTION, object, eClass);

Form code example

@Inject FormFactory formFactory; (...) formComposite = formFactory.createFormDetailComposite(parent, SWT.NONE); formComposite.init(eObject);

  • Import First Example
  • Project structure
  • Dsl and generated code
  • Run
  • Show runtime features

How it works

  • Parsley UI is built on top of EMF.Edit reflective

framework,

  • the default behavior is delegated to EMF Edit
  • or your .edit project
  • Customizations are based on Dependency Injection:
  • no need to inherit parts and composites
  • change single behaviors / aspects
  • inject them in the runtime
  • purely Java

EMF Parsley DSL

  • Implemented in Xtext, using Xbase
  • Interoperable with the Java type system
  • IDE tooling (including Debugging)
  • Specify customizations in one single file in a

compact form

  • Generates the corresponding Java code
  • Generates the Guice bindings
  • You can use the DSL and manually written Java code

together

slide-14
SLIDE 14

@EmfParsely www.eclipse.org/emf-parsley

All expressions are statically type-checked / inferred

Static type checking

DSL Java interoperability

  • Access to all Java types
  • According to project dependencies/classpath
  • DSL elements can extends your Java classes
  • DSL fully debuggable!

Imports management

  • Automatic import
  • Quick fixes

JDT Integration

slide-18
SLIDE 18

@EmfParsely www.eclipse.org/emf-parsley

All artifacts are generated and kept in synch:

  • Java implementations
  • plugin.xml
  • Fully integrated with Eclipse Building mechanism
  • All files are generated on DSL save

Customizations

There are many levels of customizations:

  • EMF Edit – the default behaviour
  • DSL customizations – the easy way
  • Google Guice / Java – not only for the brave! 

Demo from scratch

  • Create a new Project with EMF Parsley wizard
  • Use a “On Selection Tree Form” view
  • Customize to visualize an Ecore
  • Show interactions with Ecore editor

Fully EMF compliance

  • EMF Resource Compliant
  • Editing Domain
  • Notification system, Undo/Redo, DnD, etc..
  • EMF standard persistence (CDO, Teneo, XMI)

Big App friendly

EMF Parsley helps you to organize big applications

  • All customizations related to a single view are in the

same plugin

  • The DSL collects all aspects configurations /

customizations in a compact form

  • You can use Ctrl-Shift-F3 to search across projects
slide-30
SLIDE 30

@EmfParsely www.eclipse.org/emf-parsley

When a new version is released, a simple project clean will upgrade your code

  • Purely Java runtime APIs
  • No migrations needed (no model underneath)
  • If runtime is updated the DSL will do the work for

you

Easy upgrading

@EmfParsely www.eclipse.org/emf-parsley

EMF Parsley is ready to be used in production!

  • Graduation release in Neon
  • It’s used in deployed applications with both RCP and RAP

implementations

  • You can switch between persistence implementations without

much effort

Production ready
