Graphical PCM Editors

GMF-based

Development started 2006

Six diagrams

Last regeneration 2013


Component Model




Why Change a Running System?

New features should be supported

Regeneration cumbersome

Manual changes in generated code

No extensibility

GMF barely maintained

Last release in 2014

Almost no issues resolved since then

New frameworks emerging:


Component Model




New PCM Editors

-based

Work on first prototype started summer 2014

Current state

Almost feature complete

Currently being polished

Included in nightly built

Release in next stable

release spring 2017

User Benefits

Improved saving and synchronization

Layers

Better layouting out of the box


Component Model




Development Benefits

Efficiency

Dynamic evaluation

DSL-based (VSM tree)

Sufficient flexibility

Extensible

Maintainability

VSM tree enforces structure

Easy to learn, good documentation

Future proof

Actively maintained

Lively community


Component Model




Improvement Potential

Rotating border nodes

Discarding changes made on multiple models

Placement of services

Auto-completion

Debugging

Improved handling of additive extensions


Component Model




Extensibility

Ecore metamodels are extensible

Plain references

EMF Profiles

…

Editor “extensibility” in the past

Fork editor

New editor

No editor

Now

Sirius editors can be extended
