Theme usage & specialized bundles¶

Beyond the universal gen2 bundle, specialized entry points exist for diagrams that benefit from extra tweaks.

Source files

Theme .puml sources live under doubleslash/ in this repository.

System / C4-style diagrams¶

!include https://raw.githubusercontent.com/doubleSlashde/umltheme/main/doubleslash/puml-theme-gen2-system.puml

Architectural levels via stereotypes¶

The system theme recognises stereotypes for layering:

rectangle "Online Shop System" <<context>> {
    rectangle "Web Application" <<container>> {
        rectangle "Order Management" <<component>> {
            rectangle "Order Service" <<module>> {
                rectangle "OrderController.java" <<code>>
            }
        }
    }
}

Stereotype	Typical C4 lens
`<<context>>`	System context
`<<container>>`	Containers
`<<component>>`	Components
`<<module>>`	Modules / subsystems
`<<code>>`	Code-level artefacts
`<<external>>`	External systems / third parties

Full sample: systemmodel_with_levels.puml (mirror under remote_testing/ with raw URLs).

Gantt diagrams¶

Wrap with @startgantt … @endgantt and include the Gantt-oriented theme:

@startgantt
!include https://raw.githubusercontent.com/doubleSlashde/umltheme/main/doubleslash/puml-theme-gen2-gantt.puml
' ...your tasks...
@endgantt

Legacy themes (deprecated)¶

Older per-diagram URLs under the repo root (e.g. puml-theme-doubleslash-*.puml, pgantt-theme-doubleslash.puml) still resolve but are deprecated—prefer gen2 URLs from getting-started.md.
