Stronger

A few relases

To sum up

• June 2014: 1.0.0(Luna)
• October 2014: Sirius 2.0.0
• June 2015: Sirius 3.0.0(Mars)
• October 2014: Sirius 3.1.0

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

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
• ...

Faster

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

  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

Implementation Characteristics

• Small: 100 classes of non-generated code
• Evaluation: fast and collect errors as it goes
• Validation: strong and precise
• Tiny dependency surface: ease integration and deployement in other contexts
• Compliant with dynamic use cases
• Extensible with simple Java classes

Queries engines -- Overhead bench

Experimental feature for Sirius 3.0.0

Recommended query language for Sirius 3.1.0

• 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

• 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
