Python client for the PlantUML server

Project description

Plantweb is a project that provides a command line interface, Sphinx directives and an API that allows to render powerful plain text UML diagrams, ASCII diagrams and complex graphs.

It is a Python client for the PlantUML server and thus it can render PlantUML, Graphviz and Ditaa diagrams without the need to install them.

Plantweb features a local cache that prevents requesting the server for previously rendered diagrams, speeding up building documentation with lots of diagrams.

Finally, being pure Python, non-local rendering, Plantweb is an excellent way to display and render PlantUML, Graphviz and Ditaa diagrams in ReadTheDocs published documentation.
