Renders PlantUML code blocks in place, entirely in your browser. PlantUML In-Place Preview renders PlantUML code blocks as diagrams on the page. Rendering runs entirely in the browser. No PlantUML server is contacted, so diagram source never leaves your machine. The extension stores no user data. It is a maintained fork of Pegmatite. The store name was Pegmatite-gitbucket through 2.0.0. From 2.0.1 the name is PlantUML In-Place Preview. The extension ID is unchanged, so existing installs keep working after update. It renders a code block when the language is uml, puml, or plantuml, and the source starts with @start. On some sites, a missing @startuml is completed for you. Hover the diagram to show two icons. One toggles between the source and the rendered diagram. The other downloads the diagram as an SVG file, always in the light theme.
