Diagram User Experience

Resizing a container(1.0)

Resizing a container(2.0)

Positioning Things

• Snap To Shape enabled by default for new diagrams
• Snap To Grid now used when an element is created
• Resize no longer change ports or children's location
• Actions to distribute shapes
• Action to reset the diagram origin

Edges Layouting (1.0)

Edges Layouting (2.0)

Beautiful editors

Query languages

What is the type of var:source ?

Type analysis within the Action Language

Requires stronger type information from Interpreters

• Reference support in aql:
• Implemented in feature:, var:
• Improvements in [/]
• No support in legacy <%%> and ocl:

Definition Tooling : demo

• Workspace class loading is BACK
• Image path validation and selection wizard
• Quick Outline
• Prioritized sub menus
• ...

Goal : 1 Million Model Elements

Constant improvements

Big operations

• Models Footprint, ~20% improvement
  • use of MinimalEObject
  • Colors transformed from full-blown EObject to Immutable DataType
  • detection and correction of leaks
  • reduce usage of Adapters
• Save Strategy
• Improvements in the Image cache...

Latency

• Diagram Refresh
• UI Runtime
  • Model Element Selection Dialogs for big models
  • Right-click latency in the explorer
  • Better integration with EEF (property views)
• Tables
  • SWT Refreshes now done as a batch
  • Table model refresh improvements

Acceleo Query Language

Implementation specifically tailored for the Sirius use case

• Many variables for a given expression
• null values are common
• Navigation with many steps aggregating data
• Interactive use : context is constantly changing
• Complex or custom logic : Java Services
• Predictable ordering and performance overhead .

Language Characteristics

• You know OCL ? Then you know AQL
• No implicit variables

  [name/] is invalid become self.name [self.eContents()->select(name.startsWith('A'))/] is invalid and become self.eContents()->select(i | i.name.startsWith('A') self.referenceWithNoValue.someOtherAttribute has no evaluation error, returns "Nothing"

• Classic operations : filter, collect
• Convenient operations : eInverse(), eResource()..

Not strictly compatible* with MTL

*: but a subset of MTL works for both

Timeline for AQL

Starting now for deployement in Q4 : consider it

Still using <%%> :consider it

Using [/] : prepare your queries so that upgrading get easy

Demo

Me too !

• Performances depends on your .odesign specification
• Focus on queries wich would depend on the number of elements in the whole model
• Measure*, Improve, Repeat *: Sirius embedded profiler is one click away

Sirius 3.0 is a major version

Upgrading

• The runtime handles .odesign and .aird models for you
• Easy process :
  1. Check release notes for user-visible changes.
  2. Change update-site, versions
  3. In case of impacting API change, re-check the release notes for instructions

3.1 is planned for November

• Diagram UX improvements (specify selected elements after a tool application...)
• Compartments feature complete
• Bullet-proof AQL query engine
• More performance and scalability improvements

Potential other themes for 3.1

• Better SVG rendering
• Improve the i18n Story
• Prefered side for ports

Potential Themes for Eclipse Neon

• Customizable rich property views and edition wizards
• Edges from/to list elements
• Tighter integration with the workspace
• Scalability, Performance, Headless
• Your priority
