Worked on the mermaid-js/mermaid repository to deliver box-drawing character input support and parsing enhancements for treeView diagrams. Developed a dedicated preprocessor in TypeScript to convert box-drawing inputs into an indent-based internal format, integrating it with the existing parser while preserving error line mapping. Enhanced the parser to handle decorative characters and improved error reporting, contributing to more robust and ergonomic diagram creation. Maintained comprehensive test coverage with both unit and integration tests, updated documentation, and added UI demos to showcase new features. Focused on front end development, parser development, and testing using JavaScript, TypeScript, and HTML.
