View parameters expressions

Instead of injecting plain parameters, or dynamic settings into view variables, it is possible to use expressions that will be evaluated in context before being injected.

This feature is written on top of Symfony ExpressionLanguage component.

Example

ibexa:
    system:
        my_siteaccess:
            location_view:
                full:
                    article_test:
                        template: "@ibexadesign/full/article_test.html.twig"
                        params:
                            parentLocation:
                                expression: "loadLocation(location.parentLocationId)"
                            metadata:
                                expression: "{
                                    'contentTypeIdentifier': contentType.identifier,
                                    'section': repository.getSectionService().loadSection(content.contentInfo.sectionId),
                                    'owner': repository.getUserService().loadUser(content.contentInfo.ownerId),
                                    'secret': '%secret%'
                                }"
                        match:
                            Id\Location: 144
