Developed comprehensive Nu language support for the nvim-treesitter/nvim-treesitter repository by implementing a new parser and integrating syntax highlighting, indentation rules, and code injections tailored for Nu constructs. Leveraged Lua and tree-sitter to create robust highlighting queries and ensure accurate parsing behavior. Supplemented the feature with end-to-end and indentation tests to validate correctness and maintainability, while also providing clear parser installation instructions to streamline onboarding for Nu projects. The work focused on configuration and parser development, addressing the need for seamless Nu language integration and enhancing the extensibility of the nvim-treesitter ecosystem for future language support.
