Serializers

Serializers in Grammarinator have the responsibility of generating string representations from Grammarinator trees. These string representations serve as the content for the output test cases. Serializers are implemented as functions that take the root node of the tree as input and construct the output string by traversing the tree.

When using the grammarinator-generate script, the serializer can be specified using the --serializer CLI flag. When using Grammarinator from the API, the serializer can be defined in the constructor of grammarinator.tool.GeneratorTool.

A default serializer implementation is available at grammarinator.runtime.simple_space_serializer(). This serializer produces output where tokens are separated by spaces.
