NORMAL 42/200
```
## Features
- Captures text and images automatically (X11 polling & Wayland events)
- SQLite storage — images saved as JPEG (quality 70)
- Fuzzy search (`~`), regex search (`/pattern`), date filters (`after:2025-01` `before:2025-06-01`)
- Type filter: All / Text / Image (`t`)
- Per-entry AES-256-GCM encryption with Argon2 password (`e`)
- Syntax highlighting in preview (300+ languages via syntect)
- Image preview in terminal (sixel / kitty / halfblocks via ratatui-image)
- Undo last delete (`u`)
- IPC Unix socket — fully scriptable

## Build & Install
**Dependencies:** `libxcb` (X11) or Wayland libs, `libsqlite3`
```bash
# X11
cargo build --release --features x11 -p rklipd
cargo build --release -p rklip
# Wayland
cargo build --release --features wayland -p rklipd
cargo build --release -p rklip
# Install
sudo cp target/release/rklipd /usr/local/bin/
sudo cp target/release/rklip /usr/local/bin/
```
**Autostart (systemd user):**
```ini
# ~/.config/systemd/user/rklipd.service
[Unit]
Description=rklipd clipboard daemon
[Service]
ExecStart=/usr/local/bin/rklipd
Restart=on-failure
[Install]
WantedBy=default.target
```
```bash
systemctl --user enable --now rklipd
```
## Usage
```bash
rklipd [OPTIONS] # start daemon
rklip # open TUI
Options:
--max-entries <N> Max history entries (default: 500)
--max-entry-size-kb <N> Max text entry size in KB (default: 512)
--expiry-days <N> Auto-delete entries > N days
```
## Keybindings
| Key | Action |
|-----|--------|
| `j` / `↓` | Next entry |
| `k` / `↑` | Previous entry |
| `Enter` | Paste selected & quit |
| `/` | Fuzzy search mode |
| `t` | Cycle type filter (All → Text → Image) |
| `e` | Encrypt / Decrypt selected entry |
| `dd` | Delete selected (confirm) |
| `u` | Undo last delete |
| `gg` / `G` | Jump to top / bottom |
| `Ctrl+j/k` | Scroll preview |
| `:clear` | Clear entire history |
| `:p` | Set session password |
| `q` / `:q` | Quit |
**Search syntax:**
```
rust # fuzzy match
/fn\s+\w+\( # regex (prefix with /)
after:2025-01 before:2025-06 config # date filters + text
```
## Encryption
Two independent layers:
| Prefix | Method | Key source | Use case |
|--------|--------|-----------|----------|
| `enc:` | AES-256-GCM | Machine key (`master.key`) | Legacy / auto |
| `enc2:` | Argon2 + AES-256-GCM | User password | Sensitive entries |
Press `e` on any entry to encrypt/decrypt with a password. Encrypted entries show as `🔒 [Chiffré]` and require your password to paste.
## IPC (scripting)
The daemon exposes a JSON Unix socket. Example with `socat`:
```bash
# Fetch last 5 entries
echo '{"GetHistory":{"limit":5}}' | socat - UNIX-CONNECT:~/.local/share/com.zefad.rklipd/rklip.sock
# Set clipboard content
echo '{"SetClipboard":{"content":"hello"}}' | socat - UNIX-CONNECT:...
# Clear history
echo '"ClearHistory"' | socat - UNIX-CONNECT:...
```
