Version 7 (modified by Ryan J Ollos, 7 years ago) (diff)

Fixed incorrect statement about development path, and added note about creating a tag when we reach the 2.0 milestone. Added request for feedback.

The trunk is a development version that works with Trac 0.11 and later. The code is thought to be stable, but please be ready to do some testing and report defects if you intend to install it on a production system. A tag will be created for version 2.0 when the code is known to be stable. Posting a note to #9958 about your experience using the plugin would be very appreciated.

Planned Enhancements

  • Work towards v2.0, improving documentation and fixing minor defects.
  • Render plantuml files from repository #7053.


  • 19-March-2012: License changed from GPL to BSD 3-Clause, which is the license used by Trac.

Render PlantUML Diagrams


PlantUML is a java utility that allows generation of different types of UML diagrams (sequence, activity, state, use cases, ...) from a simple text description file.

This plugin allows the integration of PlantUML on Trac Wiki pages, dynamically generating and embedding the diagrams.


The plugin depends on PlantUML compiled jar being installed on the system, a valid Java runtime, and Graphviz installed and correctly configured (these are dependencies for PlantUML itself)


The following entry must be added to trac.ini:

plantuml.* = enabled

plantuml_jar = /path/to/plantuml.jar
java_bin = /path/to/java_bin (optional, if Java binary is not on the search path)
