## Description

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 selection. It also features a built-in client for the Language Server Protocol, providing real-time diagnostics, completion, and code analysis directly within the terminal interface.

Beyond its core editing capabilities, the project offers a highly customizable environment. Users can define complex keybindings, manage multiple cursors for simultaneous edits, and apply declarative styling rules to customize the visual appearance of the interface. The editor also includes robust support for file discovery, buffer management, and interactive fuzzy-matched picking for symbols and commands.

The editor includes a built-in diagnostic utility to verify the runtime environment and dependency configuration during setup.
