# Reef
> **AI 时代的最小开发者终端**
> **The minimal dev terminal for the AI coding era**
**Once AI writes your code, 90% of an IDE becomes dead weight. Reef is the other 10%.**
---
## Why
When AI writes most of your code, an IDE's surface shrinks to a handful of things: browsing files, reading files, searching, walking git diffs, and shipping the result. Reef is a terminal workbench for exactly that — and nothing else.
No autocomplete. No linter. No language server. Not even a text editor. Write with your AI tool of choice; come here to read, review, and ship — on your laptop or across an SSH connection.
## What's in the box
### Four tabs
- **Files** — tree navigator with a read-only preview: syntax-highlighted code, inline image rendering (Kitty / iTerm2 / halfblocks, auto-detected), and friendly metadata cards for binaries.
- **Search** — workdir-wide content search (ripgrep-powered, honours `.gitignore`) with live preview on the right; modal list / input modes, whole-row horizontal scroll, 1000-hit cap.
- **Git** — status with per-file `+N −M` numstat; stage / unstage per file **or per folder** (keyboard or double-click); unified or side-by-side diff; compact or full-file context; syntax-highlighted; discard (confirmed) and discard-all; push / force-push (`--force-with-lease`) behind a confirm banner.
- **Graph** — commit DAG with ref chips, inline commit detail and per-file diff. Vim-style visual mode (`V`) selects a range of commits and renders the merged diff across them; `Shift+↑/↓` or `Shift+Click` extends the range without entering visual mode.
### Palettes & overlays
- Space P — fuzzy quick-open by path.
- Space F — global content search overlay (shares the Search tab's backend; Alt+Enter pins the query into the tab).
- Ctrl+O — hosts picker: SSH hosts parsed from `~/.ssh/config` plus recently-used entries; swaps the backend live without restarting.
- h — help.
### Remote over SSH
Connect to a remote box and get the full Files / Search / Git / Graph UI — same keys, same feature set — driven through a tiny `reef-agent` daemon over SSH stdio.
```bash
reef --ssh user@host # open remote $HOME (agent auto-installed)
reef --ssh user@host:/path # open /path on host
```
- Auto-deploy: Reef detects the remote OS/arch and installs a version-matched `reef-agent` — downloaded from GitHub Releases, or uploaded from your local build as a fallback.
- One ControlMaster SSH session powers the whole thing: JSON-RPC over stdio for data, `scp` over the existing socket for drag-drop upload, `ssh -t` for `$EDITOR`.
- Content search, diff, graph, stage/unstage, file-tree create/rename/delete — all work identically remote.
### File operations
- Create, rename, move-to-trash, and hard-delete from the file tree — via toolbar, right-click context menu, or keyboard (`F2`, `d` / `Del`, `Shift+D` / `Shift+Del`).
- **Drag files from Finder / Explorer onto the terminal** to enter *place mode* — click any directory to copy the dropped files there, `Esc` or right-click to cancel. Works over SSH (uploads via the existing ControlMaster).
### Ergonomics
- **Keyboard first**, mouse where it earns its keep — drag to resize the split, double-click to toggle staging, scroll the panel under the cursor, right-click the tree for a context menu.
- **Vim-style in-panel search** — `/` and `?` open a prompt, `n` / `N` step matches, with `Alt`/`Ctrl` word-editing shortcuts in the prompt.
- **Navigation**: `↑` / `↓`, `j` / `k`, and `Ctrl+P` / `Ctrl+N` / `Ctrl+K` / `Ctrl+J` all move the selection on every tab.
- **Selection & clipboard** — `v` toggles mouse capture so the terminal's native text selection works; or drag inside a preview pane and Reef copies to the system clipboard via OSC 52 (no helper binary, works over SSH).
- **Auto-themes** — OSC 11 probe picks up terminal light/dark mode; locale auto-detects (English / 简体中文).
- **Persistent prefs** — diff layout, diff mode, recent SSH hosts, and friends survive restarts.
## Install
### Via npm (recommended)
```bash
# Run without installing
npx @reef-tui/cli
# Or install globally
npm install -g @reef-tui/cli
reef
```
The correct native binary for your platform is selected automatically.
Supported: macOS (arm64, x64), Linux (arm64, x64), Windows (x64).
### Build from source
```bash
cargo build --release
# Run from inside any git repo:
cd your-git-repo
/path/to/reef/target/release/reef
```
Reef works anywhere. Outside a git repo, the Git and Graph tabs show a "Not a git repository" placeholder; the Files tab still browses the current directory. If you start Reef in a non-repo with no recent hosts, the hosts picker opens so you always have a visible path forward.
## Keybindings
### Global
| Key | Action |
| --- | --- |
| `q`, `Ctrl+C` | quit |
| `1` / `2` / `3` / `4` | Files / Search / Git / Graph tab |
| `Tab` | cycle tabs |
| `Shift+Tab` | switch focused panel |
| `h` | help |
| `Space p` | quick-open file (fuzzy path) |
| `Space f` | global content search overlay |
| `Ctrl+O` | hosts picker (open SSH target) |
| `v` | toggle mouse capture (for terminal text selection) |

| `Ctrl+K` / `Ctrl+J` | navigate (alt) |
| `PgUp` / `PgDn` | page |

### Files tab
| Key | Action |

| `d` → `y` | discard unstaged file / folder (confirm) |
| `Enter` / `e` | open selected file in `$EDITOR` |

| `Esc` | exit visual mode / clear range |
| `m` / `f` | commit-file diff layout / mode |
| `t` | tree / flat changed files |
## Status
Alpha. Single-process Rust binary — no plugins, no IPC on the local path. Files, Git, and Graph are host-native; remote uses a thin `reef-agent` daemon over SSH stdio. One codebase, one UI, one key map — local and remote are feature-parity.
