Worked on the DioxusLabs/dioxus repository to address a formatting issue affecting RSX commented-out blocks, focusing on preserving indentation within the autofmt workflow. Applied targeted changes to the Rust codebase, refining the logic for write_rsx_block and handling of trailing comments to ensure consistent child-level indentation and removal of stray tabs. Introduced regression tests for multiple RSX comment variants, validating idempotency and guarding against future formatting regressions. This work improved code readability and maintainability for developers working with RSX, leveraging skills in Rust, code formatting, and test-driven development to enhance the reliability and consistency of the Dioxus framework’s formatting tools.
