Helix
What Helix is
Helix is a free text editor for working in a terminal, available on Linux, macOS, and Windows. Its editing model uses multiple selections as a core tool, so commands can act on several selections at once. Multi-cursor editing and macro recording are supported. Tree-sitter integration provides syntax highlighting, indentation calculation, and code navigation, while built-in language server support offers completion, go to definition, documentation, and diagnostics. To use those language features for a preferred programming language, users need to install its language server.
The editor can navigate and select functions, classes, comments, and syntax tree nodes. Built-in tools include a fuzzy finder for files and symbols, project-wide search, themes, automatic bracket pairing, and surround integration. Written in Rust, Helix can be used in a terminal, over SSH, or in tmux. Settings can be configured globally or by project, including themes, keybindings, and language-specific options; language servers and formatters are configured through languages.toml files. Installation guidance recommends an operating system package manager and also links to pre-built binaries. Helix has no plugin system at present, though one is intended for the future.
