Twig extends WriterAbstract
in package
implements Initializable, WithCustomSettings uses IoTrait

FinalYes

A specialized writer which uses the Twig templating engine to convert templates to HTML output.

This writer support the Query attribute of a Transformation to generate multiple templates in one transformation.

The Query attribute supports a simplified version of Twig queries and will use each individual result as the 'node' global variable in the Twig template.

Example:

Suppose a Query indexes.classes is given then this writer will be invoked as many times as there are classes in the project and the 'node' global variable in twig will be filled with each individual

When using the Query attribute in the transformation it is important to use a variable in the Artifact attribute as well (otherwise the same file would be overwritten several times).

A simple example transformation line could be:

<transformation
    writer="twig"
    source="templates/twig/index.twig"
    artifact="index.html"
/>

This example transformation would use this writer to transform the index.twig template file in the twig template folder into index.html at the destination location. Since no Query is provided the 'node' global variable will contain the Documentation Set Descriptor of the Object Graph.

A complex example transformation line could be:

<transformation
    query="indexes.classes"
    writer="twig"
    source="templates/twig/class.twig"
    artifact="{{name}}.html"/>

This example transformation would use this writer to transform the class.twig template file in the twig template folder into a file with the 'name' property for an individual class inside the Object Graph. Since a Query is provided will the 'node' global variable contain a specific instance of a class applicable to the current iteration.
