Origins of an OSS project

Going OSS

Mission Statement

“Lower the barrier of entry to create and deploy state of the art tools, for any domain language.”

Sirius 0.9

☑ renamed and on Eclipse.org

Sirius 1.0

☑ infrastructure and team 100% operational

Sirius 2.0

☑ up to speed

What happens next ?

A "few" relases

A "few" relases

Major versions!

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

Acceleo Query Language

Implementation specifically tailored for the Sirius use case

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

  aql:name is invalid and become aql:self.name

  aql:self.eContents()->select(name.startsWith('A')) is invalid and become aql:self.eContents()->select(i | i.name.startsWith('A')

  self.referenceWithNoValue.someOtherAttribute has no evaluation error, and returns "Nothing"

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

Not strictly compatible* with MTL

*: but a subset of MTL works for both

Queries engines -- Overhead bench

• in preference to Acceleo 3 or OCL
• simpler for querying EMF models
• more concise and very easy to learn
• improved code completion
• improved syntax errors detection

Recommended query language for Sirius 3.1.0

Diagram User Experience

Resizing a container (1.0)

Resizing a container (2.0)

Positioning Things

• Snap To Shape enabled by default for new diagrams
• Snape To All Shapes mode (F4)
• 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)

Edges label instability (3.0)

Edges labels stability (3.1)

Bi-directional link with editor

Selection after tool execution

Beautiful editors

Anchor on borders 1.0

Anchor on borders 3.0

Underlined and Strike-through style for labels

Customizable border style

Compartments

• 
• Full blown "Mapping"
  • static or dynamic number of compartments
  • leverage queries

Compartments

Complete with 3.1

• Corner cases and polish for 3.1
• Collapse

Compartments

Complete

First steps

Faster

Goal : 1 Million Model Elements

Demo

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

Sirius needs you !

• 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

A Bright Future

Sirius : Rich property views

Things we ♡ in Sirius ...

• Define your properties in the .odesign file
• Dynamic, no code generation involved
• Flexible even for complex Ecore models

... applied for the property views

Early adopters

Already in Sirius 4.0

• Possibility to contribute SVG shapes : stencils pack
• API to control the "tab-bar"
• Improvement on edge reconnection feedback

Other potential Themes for Eclipse Neon

• Bugfixes, Scalability, Performance, Headless
• Better SVG rendering
• Better integration with EMF Edit
• Prefered side for ports
• Improve the i18n Story
• Your priority

Long term, one step at a time

Push limits

Scalability, Improvements in underlying technologies

Sirius Everywhere

Embeddable, reduced dependencies
