Worked on enhancing the Go language server in the zed-industries/zed repository by introducing semantic token highlighting for format string interpolations such as %s. This feature was implemented by adding a new semantic token rule and updating the semantic_token_rules.json configuration, leveraging Go, JSON, and the Language Server Protocol. The update improves code readability and navigation for Go developers by visually distinguishing format arguments within strings. Release notes were prepared to document the change, and performance considerations were reviewed to ensure minimal impact. No bugs were addressed during this period, with the primary focus on delivering this targeted feature enhancement.
