Configuration editor

[ekuiter]

Editing configurations will make this editor much more useful.

Configurations are a new kind of editable object in a project (see #14), associated with a feature model.
They consist of a set of selected and a set of deselected features from the feature model.
The editor should provide an interface for determining these sets.

A first interface will be similar to FeatureIDE's editor, using checkboxes in a tree view and the decision propagation algorithm, but other interfaces (layouts) may be added. The editor verifies that a configuration is valid. A configuration can be exported in different formats and maybe forwarded in an automated fashion to other webservices (to allow for product generation).

Special consideration is necessary if the feature model is edited while an associated configuration is open (which may happen rather often).

In combination with roles (see #12), it may also be interesting to provide prepared templates (or "generation of configuration editors") that can be configured for public usage, or that can be exported into simple HTML (similar to ekuiter/feature-configurator).
