Helix is a terminal-based modal text editor designed for efficient code manipulation and navigation. It centers on a selection-first editing model, where operations are performed on active ranges rather than individual cursor positions, allowing for precise control over text and code structures. The editor distinguishes itself through deep integration with structural parsing and language intelligence. By utilizing an incremental parsing library, it builds concrete syntax trees that enable advanced features like structural code navigation, intelligent indentation, and syntax-aware text object
Helix maps syntax nodes to selectable text objects like functions or classes by creating query files that enable precise code manipulation.
