Helix Editor

Helix is a terminal-based text editor designed for efficient code editing, drawing inspiration from modal editors like Kakoune and Vim but built from scratch in Rust. It features multiple selections and cursors as a core editing primitive, allowing for concurrent code manipulation. A key differentiator is its deep integration with Tree-sitter, which provides robust syntax trees for enhanced syntax highlighting, intelligent indent calculation, and powerful code navigation, enabling users to select and manipulate syntax tree nodes rather than just plain text. The editor offers out-of-the-box support for Language Server Protocol (LSP) features like auto-completion, go-to definition, documentation, and diagnostics without additional configuration. It's built for the terminal, making it lightweight and efficient, suitable for use over SSH or in tmux, and avoids the overhead of Electron or JavaScript. Helix is ideal for developers seeking a modern, fast, and highly capable modal editor with powerful built-in features like a fuzzy finder, project-wide search, and themes, all while maintaining a small codebase and modern defaults.
