Eclipse Sprotty™

Primary tabs

Scope:

Within the scope of Eclipse Sprotty™ are

Diagrams to browse and manipulate models in web applications.
Support for a distributed runtime: share the workload between a client and server.
An extensible protocol for the communication between client and server
Diagram authoring facilities: choosing the content of a diagram, arranging diagram elements manually, adding/removing diagram elements, exploring the neighborhood of an element, reconciling a diagram with changes of the underlying model, trigger auto-layout.
Diagram navigation facilities: open elements, drill up/down, zoom/scroll/center/fit, selection etc.
Graphical editing facilities: changing the underlying model via the diagram, create/delete/change/customize/connect elements, undo/redo etc.
Exporting diagrams to a vector-based graphics format.
Integration with Xtext and LSP to visualize programming artifacts.
Integration with IDE frontends like Eclipse Theia or Eclipse IDE.
Integration with auto-layout engines such as the ELK.

Out of scope are

Auto-layout algorithms for diagrams. We rely on existing frameworks like ELK instead.
Visualization of huge datasets, like statistical data or timeseries. These are much better handled with frameworks like D3.js. Sprotty focusses on models, i.e. connected elements with fewer properties.
3-dimensional visualization.
Specific model editors/views, e.g. for UML. Of course, Sprotty can be used to implement such a thing, but this should be done in separate downstream projects.
Tools to author specific diagram editors, like GMF Tooling or Sirius do.
