Feb 1, 2025February 2025 — nvim-treesitter/nvim-treesitter: Delivered focused syntax highlighting and parsing improvements across Hyprlang, TypeScript, and Just recipes. Hyprlang parser now supports bash injection inside executable string literals, enhancing binding definitions and executable-string handling. TypeScript highlighting now covers awaited expressions (with type parameters) and abstract methods to improve readability. Just recipes highlighting was refined to better recognize default attributes, builtin attributes, and special attribute arguments. These changes collectively improve code understanding, reduce cognitive load for developers, and extend editor-level language support with minimal disruption.
