# lel

Python X11 STT daemon that records audio, runs Whisper, logs the transcript, and can optionally run AI post-processing before injecting text.

## Requirements

- X11 (Wayland support scaffolded but not available yet)
- `sounddevice` (PortAudio)
- `faster-whisper`
- `llama-cpp-python`
- Tray icon deps: `gtk3`, `libayatana-appindicator3`
- Python deps (core): `pillow`, `faster-whisper`, `llama-cpp-python`, `sounddevice`
- X11 extras: `PyGObject`, `python-xlib`

System packages (example names): `portaudio`/`libportaudio2`.

## Python Daemon

Install Python deps:

X11 (supported):

```bash
uv sync --extra x11
```

Wayland (scaffold only):

```bash
uv sync --extra wayland
```

Run:

```bash
uv run python3 src/leld.py --config ~/.config/lel/config.json
```

## Config

Create `~/.config/lel/config.json`:

```json
{
  "daemon": { "hotkey": "Cmd+m" },
  "recording": { "input": "0" },
  "stt": { "model": "base", "device": "cpu" },
  "injection": { "backend": "clipboard" }
}
```

Recording input can be a device index (preferred) or a substring of the device
name.

The LLM model is downloaded on first startup to `~/.cache/lel/models/` and uses
the locked Llama-3.2-3B GGUF model.
Pass `-v/--verbose` to see verbose logs, including llama.cpp loader logs; these
messages are prefixed with `llama::`.

## systemd user service

```bash
mkdir -p ~/.local/bin
cp src/leld.py ~/.local/bin/leld.py
cp systemd/lel.service ~/.config/systemd/user/lel.service
systemctl --user daemon-reload
systemctl --user enable --now lel
```

## Usage

- Press the hotkey once to start recording.
- Press it again to stop and run STT.
- The transcript is logged to stderr.

Wayland note:

- Running under Wayland currently exits with a message explaining that it is not supported yet.

Injection backends:

- `clipboard`: copy to clipboard and inject via Ctrl+Shift+V (GTK clipboard + XTest)
- `injection`: type the text with simulated keypresses (XTest)

AI provider:

- Generic OpenAI-compatible chat API at `ai_base_url` (base URL only; the app uses `/v1/chat/completions`)

Control:

```bash
make run
```
