Worked on the racket/racket repository to enhance the raco command line interface by introducing Markdown documentation output alongside the existing PDF format. Focused on Racket programming and command line interface design, the work involved adding a --doc-markdown flag to raco setup, updating flag parsing logic to ensure the new option persisted through pre-flag parsing, and integrating Markdown generation into the documentation setup flow. This addition streamlined documentation workflows, enabling automated pipelines and Markdown-based publishing. The changes improved reliability and flexibility in documentation generation, reduced manual intervention, and aligned with common developer practices for multi-format documentation output in Racket projects.
