Ethan Hayng developed Mach language support for the zed-industries/extensions repository, enabling Mach development within the editor through a comprehensive feature set. He implemented syntax highlighting using tree-sitter-mach, auto-indentation, bracket matching, and comment toggling, ensuring a smooth editing experience. By integrating Language Server Protocol (LSP) features such as diagnostics, hover, go-to-definition, completion, and document symbols, Ethan provided robust editor assistance for Mach code. His work leveraged Git and TOML, and extended the extension ecosystem with a dedicated Mach extension repository. The project demonstrated depth by addressing both core editing capabilities and advanced language tooling within a single release cycle.
February 2026: Mach language support in editor added for zed-industries/extensions, with syntax highlighting, auto-indentation, bracket matching, and comment toggling, plus LSP integration for diagnostics and navigation. This work enables Mach development in the editor and sets the foundation for broader language support.
