Contributed to the ggml-org/llama.cpp repository by addressing a nuanced issue in the web UI’s syntax highlighting during streaming mode. Focused on stabilizing color coding for non-common programming languages, the work involved updating the frontend JavaScript to ensure consistent highlighting both during and after streaming. This required passing the complete lowlight language set to rehype-highlight and rebuilding static UI assets to synchronize frontend and backend changes. By aligning the streaming and non-streaming code paths, the update improved reliability for users working with diverse languages, reduced confusion, and established a more robust foundation for future web development enhancements.
