HN 표시: Attn – <20MB 바이너리의 마크다운 뷰어 및 편집기(Rust)

A markdown viewer for people who live in the terminal. One command. Native window. No Electron. Install · Issues · Contributing attn . That's it. A native window opens with your project's markdown rendered beautifully — with live reload, a file tree, tabs, and a built-in editor. No config, no browser, no 200MB runtime. Most markdown previewers are either browser tabs you have to manually refresh, or Electron apps that eat your RAM for breakfast. attn is a single <20MB binary. It forks to background as a daemon, opens a native macOS window, and watches your files. Edit in Vim, VS Code, whatever — attn reloads instantly. Open another file? It joins the same window as a tab. What you get: - Live reload — save a file, see the change. No refresh button. - Interactive checkboxes — click a - [ ] task and it writes back to the file. - Built-in editor — hit Cmd+E to toggle a full ProseMirror editor with syntax highlighting, math, and mermaid diagrams. - File tree + fuzzy search — browse your project with Cmd+P . Lazy-loads folders so it's fast on huge repos. - Tabs + projects — open multiple files, switch between projects with Cmd+; . attn remembers your workspaces. - Mermaid diagrams — flowcharts, sequence diagrams, and more render inline from fenced code blocks. - Media support — images (with zoom/pan), video, and audio play natively. - Paper & ink themes — warm parchment light theme by default, cool dark theme with --dark . - Single instance — run attn from ten terminals. One daemon, one window, new tab each time. brew install lightsofapollo/attn/attn npx attnmd # or npm install -g attnmd && attn cargo install attn git clone https://github.com/lightsofapollo/attn.git cd attn && cargo install --path . Requires Rust 1.85+. For npm installs, Node 18+ is required. attn # open current directory attn README.md # open a file attn ~/projects/myapp # open a project attn --dark # force dark mode attn --status todo.md # print task progress: "3/5 tasks complete" attn --json spec.md # dump document structure as JSON | Shortcut | Action | |---|---| Cmd+P | Fuzzy file search | Cmd+E | Toggle editor | Cmd+F | Find & replace | Cmd+; | Switch project | Cmd+W | Close tab | Cmd+Tab / Cmd+Shift+Tab | Navigate tabs | Cmd+= / Cmd+- | Zoom in / out | Cmd+0 | Reset zoom | Cmd+/ | Show all shortcuts | The Svelte 5 frontend is compiled by Vite and embedded into the Rust binary at build time. No bundled web server, no extracted assets — it's a single self-contained executable. First launch forks a daemon to the background. The daemon opens a native window via wry (the same webview engine behind Tauri) and listens on a Unix socket. Subsequent attn calls connect to the socket and open new tabs in the existing window. If the binary changes (you rebuild), the old daemon is automatically replaced. src/ main.rs CLI, native window, keyboard shortcuts daemon.rs Unix socket IPC, single-instance daemon watcher.rs File system monitoring with debouncing markdown.rs Structure extraction (tasks, phases, file refs) ipc.rs Webview ↔ Rust messaging files.rs File tree, media type detection projects.rs Project registry web/src/ Svelte 5 frontend web/styles/ Tailwind CSS task dev # Vite HMR + Rust in foreground task dev ATTN_PATH=path/to/file.md # Open a specific file The task dev command starts Vite for hot module replacement and runs the Rust binary in foreground mode, pointed at the Vite dev server. scripts/build.sh # Debug build scripts/build.sh release # Release build scripts/build.sh prod # Production build
