Worked on the zed-industries/zed repository to enhance TSX readability by refining the rainbow colorization feature. Focused on front end development and visual design, the developer used Scheme to exclude angle brackets from rainbow highlighting within TSX files, reducing visual noise and aligning TSX behavior with HTML for JSX tags. The technical approach involved updating the brackets.scm file to set exclusion flags for specific bracket patterns, ensuring more predictable syntax highlighting. This targeted change improved developer focus and consistency across languages, and was thoroughly documented in the release notes, laying a foundation for clearer code reviews and future colorization improvements.
