Plugins

Plugins can be used where more control or customisation is required, and provide access to the workspace via the Structurizr for Java library. For example, you could use a plugin to create model elements based upon an external data source, or perhaps define views programmatically. Plugins can be used at any point in the DSL.

To write a plugin, create a Java class that implements the com.structurizr.dsl.StructurizrDslPlugin interface (you will need to add a dependency on the DSL library, which can be found on Maven Central via com.structurizr:structurizr-dsl).

package com.example;

import com.structurizr.Workspace;

public class TestPlugin implements StructurizrDslPlugin {

    @Override
    public void run(StructurizrDslPluginContext context) {
        Workspace workspace = context.getWorkspace();
        workspace.setName("Name set by plugin");
    }

}

The compiled plugin packaged as a JAR file (plus any other JAR dependencies) should be placed in a directory named plugins next to your DSL file. You can then use your plugin from the DSL using the !plugin keyword.

``` workspace {

!plugin com.example.TestPlugin

}

Parameters can be specified in the plugin body, for example.

 ```
 workspace {

    !plugin com.example.TestPlugin {
        name value
    }

}

The named parameters are then available via the getParameter(name) method of the StructurizrDslPluginContextobject.

Please note that !plugin is currently an experimental feature.
