6 Commits • 1 Features
Oct 1, 2025Delivered a focused set of diff-view improvements for metacraft-labs/codetracer in 2025-10, prioritizing reliability, navigation, and editor stability. Key features include a dedicated diff-file-path component, click-to-open editor, and color-coded indicators for added/changed/deleted files, enhancing review clarity and speed. Addressed UI reliability by reapplying diff indicators after view state changes, fixed edge-case rendering when the first line is deleted, and improved scroll/trace behavior. Strengthened editor lifecycle by preventing duplicate editors per line and ensuring unique selectors in multi-editor scenarios. Overall, these changes increase correctness of diffs, reduce reviewer friction, and improve maintainability of the diff-view codebase.
