# rhun
> rhun is a small, very fast code editor for Linux (x86-64), macOS (Apple silicon) and Windows (x64), written in assembly. It has tabs, a file explorer, syntax highlighting for 127 languages and file formats, find and replace, a built-in terminal, Git history and diffs, fuzzy search, an optional Vim mode, 40 color themes and an agents panel that shows Claude Code and Codex sessions live. Free and open source (MIT). Current version: 0.17.13.
Facts:
- One static binary under 700 KB on Linux (fonts, themes and grammars included), with no libc, toolkit or runtime. It draws every pixel itself and speaks Wayland and X11 directly; on macOS the same source is translated to native Apple silicon code and runs in an AppKit window. Windows uses an assembly Win32 adapter and ConPTY.
- Install on Linux and macOS: `curl -fsSL https://github.com/vshvedov/rhun/releases/latest/download/install.sh | sh` (or `wget -qO-`). No root; checks SHA-256 checksums and, on macOS, the developer signature. Uninstall: add `sh -s -- --uninstall`.
- Updates: rhun checks GitHub once a day in the background; the status bar offers a new version, installs it and restarts into it on Windows, Linux and macOS. Windows stages a checksum-verified release and installs it after the editor exits for restart; writable ZIP installations also update in place.
- Settings: `~/.config/rhun/config`, applied while running. Grammars: `~/.config/rhun/syntax/NAME.syn`. Themes: `~/.config/rhun/themes/NAME.theme`.
- Windows: Windows 10 version 1809 or later, x64. Extract the Windows ZIP and open rhun.exe, or use the one-command PowerShell installer shown on the website. No package manager is required. Settings are in %APPDATA%\rhun, sessions in %LOCALAPPDATA%\rhun. Native ARM64, code signing and the Unix control socket are not included.
