Helix

What Helix is

Helix is a free text editor designed for terminal use on Linux, macOS and Windows. It treats multiple selections as a core editing tool, allowing commands to work on selections concurrently; multi-cursor editing and macro recording are supported. Tree-sitter integration provides syntax highlighting, indentation calculation and code navigation. Built-in language server support offers completion, go to definition, documentation and diagnostics, though users need to install language servers for their preferred programming languages. Helix can navigate and select functions, classes, comments and syntax tree nodes. Other 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 run in a terminal, over SSH or in tmux. Settings can be global or project-specific and include themes, keybindings and language-specific options; language servers and formatters can be configured through languages.toml files. Helix currently has no plugin system, although one is intended for the future. Its site describes a GUI frontend as a future possibility.
