Support for `plantuml` XML tag

[rdeterre]

Hello all,

Would it be feasible to add support for UML in breathe?

Doxygen has added support for this in version 1.8.8 with a "startuml" special command that generates <plantuml> XML tags, and sphinx has a "sphinxcontrib-plantuml" extension that adds uml directives.

Hi,

I think this is something that can be implemented without too much trouble. Just there should be some runtime checks for sphinxcontrib-plantuml, so we don't hard-depend on it. Good enhancement.

Right now Breathe is kind of having maintenance only due to a lack of active developers, so unless someone steps up I am afraid this will not be implemented for a while.

I second that idea.
