MarkdownTransformer + MarkdownPipeline#5

Description

opened on Aug 24, 2026

Implement the core composition types for the transformation pipeline.

Scope

  • MarkdownTransformer — functional interface (SAM) receiving and returning a MarkdownDocument
  • MarkdownPipeline — ordered composition of MarkdownTransformer instances; applies each in sequence

Notes

  • Transformers may mutate the AST in-place and return the same document, or return a new one — the interface should support both
  • MarkdownPipeline should be easy to construct both programmatically and from a Gradle task config

Acceptance criteria

  • Multiple transformers compose correctly and execute in declared order
  • An empty pipeline returns the document unchanged

                              Implement the core composition types for the transformation pipeline.
                              Scope
                              • MarkdownTransformer — functional interface (SAM) receiving and returning a MarkdownDocument
                              • MarkdownPipeline — ordered composition of MarkdownTransformer instances; applies each in sequence
                              Notes
                              • Transformers may mutate the AST in-place and return the same document, or return a new one — the interface should support both
                              • MarkdownPipeline should be easy to construct both programmatically and from a Gradle task config
                              Acceptance criteria
                              • Multiple transformers compose correctly and execute in declared order
                              • An empty pipeline returns the document unchanged
