From 7cb68807fbd2138bfc71ace3548e4366d15daacf Mon Sep 17 00:00:00 2001 From: Paul Beesley Date: Fri, 12 Jul 2019 11:56:58 +0100 Subject: [PATCH] doc: Generate PlantUML diagrams automatically Currently we have some pre-rendered versions of certain diagrams in SVG format. These diagrams have corresponding PlantUML source that can be rendered automatically as part of the documentation build, removing the need for any intermediate files. This patch adds the Sphinx "plantuml" extension, replaces references to the pre-rendered SVG files within the documents, and finally removes the SVG files and helper script. New requirements for building the docs are the "sphinxcontrib-plantuml" Python module (added to the pip requirements.txt file) and the Graphviz package (provides the "dot" binary) which is in the Ubuntu package repositories.
