Generalisation

PlantUML now can generate diagrams other than UML. In such cases the usual @startuml does not make sense anymore. So now we allow diagrams start with @startXYZ and finish with @endXYZ, where XYZ can change with the type of diagram and can be any characters (including spaces).

This means that plugin developers are encouraged to change their code to recognize @start instead of @startuml.

DITAA diagrams are usually formatted as @startditaa...@endditaa.

Ditaa

Ditaa (DIagrams Through Ascii Art) is an Open Source project that allows to generate general diagrams from a text descriptions. The idea is close to PlantUML, and it may be useful for documentation to generate other diagrams than UML.

So last version of PlantUML allows this :

If your plugin does not support @startditaa yet, a temporary feature has been set up : it is also possible to use Ditaa with @startuml by using ditaa keyword on the very first line of your description.

⚠ On PlantUML, only PNG generation is supported.

Option supported by PlantUML

You can also use some option, after the @startditaa or ditaa keyword:

  • -E or --no-separation to remove separator
  • -S or --no-shadows to remove shadow
  • scale=<XYZ> to scale up or down the diagram
