Custom Diagram

You can easily create custom diagrams based on the data in the model. You define the data collection, and the ´builders´ module takes care of the rest.

def _collector(
    target: m.ModelElement,
) -> cabc.Iterator[m.ModelElement]:
    visited = set()
    def collector(
        target: m.ModelElement,
    ) -> cabc.Iterator[m.ModelElement]:
        if target.uuid in visited:
            return
        visited.add(target.uuid)
        for link in target.links:
            yield link
            yield from collector(link.source)
            yield from collector(link.target)
    yield from collector(target)

model = capellambse.MelodyModel("tests/data/ContextDiagram.aird")
obj = model.by_uuid("c403d4f4-9633-42a2-a5d6-9e1df2655146")
diag = obj.context_diagram
diag.render("svgdiagram", collect=_collector(obj)).save(pretty=True)

To understand the collection have a look into the builders module.
