Helix — A Post-Modern Modal Text Editor

Helix is a post-modern modal text editor inspired by Kakoune. Written in Rust with batteries-included defaults: Tree-sitter, LSP, multi-cursor, selection-first editing, and beautiful themes. Zero-config replacement for Vim for most users.

Quick Use

Use it first, then decide how deep to go

This block should tell both the user and the agent what to copy, install, and apply first.

# Install
brew install helix                       # macOS
sudo apt install helix                   # Debian/Ubuntu
cargo install --locked helix-term        # From source

# Launch
hx file.rs

Config ~/.config/helix/config.toml:

theme = "onedark"

[editor]
line-number = "relative"
mouse = true
bufferline = "multiple"
cursorline = true

[editor.cursor-shape]
insert = "bar"
normal = "block"
select = "underline"

[editor.indent-guides]
render = true

[editor.lsp]
display-messages = true

Key idea: selection first, then action (opposite of Vim).

  • w — select word
  • x — select line
  • s — select matching pattern
  • d — delete selection
  • c — change selection
  • % — select whole file
Intro

Helix is a post-modern modal text editor inspired by Kakoune and Neovim. Written in Rust with a batteries-included philosophy: Tree-sitter, LSP, multi-cursor, fuzzy file picker, and themes are all built in — no plugin manager needed for most workflows. Selection-first editing model where you pick targets before applying commands.

What Helix Does

  • Multi-cursor native — selection + cursors as first-class primitives
  • Tree-sitter — semantic selection via Alt+o/i (expand/shrink)
  • LSP — built-in client for any LSP server
  • Fuzzy picker — space+f file picker with preview
  • Pickers — buffers, symbols, workspace symbols, diagnostics
  • Themes — 100+ built in
  • Tutor — hx --tutor for interactive tutorial
  • No plugins yet — scheme-based plugin system WIP

Architecture

Rust terminal editor. Uses Ratatui for rendering, crossterm for events, Tree-sitter for parsing, tower-lsp for LSP. Selection-first model: every action operates on the current selection.

Self-Hosting

CLI editor, single Rust binary.

Key Features

  • Batteries-included (no plugin hunt)
  • Multi-cursor first-class
  • Tree-sitter semantic selections
  • Built-in LSP client
  • 100+ themes
  • Fuzzy file picker
  • Visual tutor
  • Fast startup
  • Crash-safe autosave

Comparison

Editor Model Config Plugins Batteries
Helix Kakoune-like TOML WIP Yes
Neovim Vim Lua Huge No (DIY)
Vim Vim Vimscript Large No
Kakoune Own kakrc Scripts Partial
VS Code Mouse + shortcuts JSON Huge Yes

常见问题 FAQ

Q: 没 plugin 可以吗？ A: 内置功能已经覆盖 80% Vim 插件生态（LSP、tree-sitter、pickers、git）。plugin system 正在开发中。

Q: Vim 用户能适应吗？ A: 需要一两小时：从 verb-noun（Vim）切到 noun-verb（Helix）。例：Vim dw → Helix wd。运行 hx --tutor 系统学习。

Q: 性能如何？ A: Rust 编写，启动 <50ms，大文件流畅。比 VS Code 快一个数量级。
