SVG export with semantic data [message #1734434]

Hi,

I'm using Sirius 3.1.4.
I'm trying to understand how I could export a Sirius diagram to SVG with semantic information attached to the SVG nodes.
More precisely, I want to have the name of the semantic elements as attributes of the corresponding SVG nodes:

<g name="semantic name" ...>
...
</g>

Is there a proper way to achieve that or something close to it ?

I've debugged the SVG export down to org.eclipse.sirius.diagram.ui.edit.api.part.AbstractDiagramEdgeEditPart.ViewEdgeFigure.paintFigure(Graphics)
in which the semantic element can be resolved. The corresponding SVG element exists but is not accessible: it's hidden in graphics.graphics.graphics2D.domGroupManager.currentGroup.
So if I manage to override ViewEdgeFigure.paintFigure somehow, I can hack with java reflection but it is far from a "proper" solution.

What would you advise ?

Hello,

Indeed, adding information in attributes during SVG is not a
functionality handled by Sirius. I do not have a better solution than
yours. You can check the following documentation presenting how to
override EditParts and figure:
https://www.eclipse.org/sirius/doc/developer/extensions-provide_custom_style.html

Steve
