# LRX-CLI

A CLI tool for fetching LRC lyrics on Linux. Automatically detects the currently playing track via MPRIS/DBus and retrieves the best-matching lyrics from multiple sources, ranked by confidence scoring.

## Sources

Sources are queried in order. High-confidence results (exact match or manual insert) terminate the pipeline early; otherwise all sources are tried and the highest-confidence result wins.

1. **Local** — sidecar `.lrc` files or embedded audio metadata (FLAC, MP3)
2. **Cache Search** — fuzzy cross-album lookup in local cache
3. **Spotify** — synced lyrics via Spotify's API (requires `SPOTIFY_SP_DC` and Spotify trackid)
4. **LRCLIB** — exact match from [lrclib.net](https://lrclib.net) (requires full metadata)
5. **Musixmatch (Spotify)** — Musixmatch API with Spotify trackid (requires `MUSIXMATCH_USERTOKEN` and Spotify trackid)
6. **LRCLIB Search** — fuzzy search from lrclib.net (requires at least a title)
7. **Musixmatch** — Musixmatch API with metadata search (requires `MUSIXMATCH_USERTOKEN` and at least a title)
8. **Netease** — Netease Cloud Music public API
9. **QQ Music** — QQ Music via self-hosted API proxy (requires `QQ_MUSIC_API_URL` that provides the same interface as [tooplick/qq-music-api](https://github.com/tooplick/qq-music-api))

> I'm aware that Spotify's lyrics are provided by Musixmatch, but the fact is that Musixmatch's own search will yield different (and more) results than Spotify's, so I treat them as separate sources.

## Usage

See `lrx --help` for full command reference. Common use cases:

- Fetch lyrics for the currently playing track:

  ```bash
  lrx fetch
  ```

  targeting a specific player and a source to fetch from:

  ```bash
  lrx --player mpd fetch --method lrclib-search
  ```

- Search by metadata (bypasses MPRIS):

  ```bash
  lrx search -t "My Love" -a "Westlife"
  lrx search --trackid "5p0ietGkLNEqx1Z7ijkw5g"
  ```

  or by path to a local audio file:

  ```bash
  lrx search --path "/path/to/Westlife - My Love.flac"
  ```

- Export to sidecar `.lrc` file (or `.txt` with `--plain`):

  ```bash
  lrx export
  lrx export --plain
  lrx export --output /path/to/lyrics.lrc
  ```

- Cache management:

  ```bash
  lrx cache stats                    # statistics with source×status table and confidence distribution
  lrx cache query                    # inspect cache entries for current track
  lrx cache clear                    # clear cache of current track
  lrx cache clear --all              # clear entire cache
  lrx cache confidence spotify 100   # manually set confidence for a source
  ```

## Configuration

Set credentials via environment variable or `.env` file:

- `~/.config/lrx/.env` — user-level
- `.env` in working directory — project-local
- Shell environment — highest priority

```env
SPOTIFY_SP_DC=your_cookie_value
MUSIXMATCH_USERTOKEN=your_musixmatch_usertoken
QQ_MUSIC_API_URL=https://api.example.com
PREFERRED_PLAYER=spotify
```

- `SPOTIFY_SP_DC` — required for Spotify source. Defaults to empty (disabled Spotify source).
- `MUSIXMATCH_USERTOKEN` — required for Musixmatch sources ([Curators Settings Page](https://curators.musixmatch.com/settings) -> Login (if required) -> "Copy debug info")
- `QQ_MUSIC_API_URL` — required for QQ Music source. Defaults to empty (disabled QQ Music source).
- `PREFERRED_PLAYER` — preferred MPRIS player when multiple are active. Defaults to `spotify`. Only used when no `--player` flag is given and more than one player (or none of them) is currently playing.

Shell completion (zsh/fish/bash):

```bash
lrx --install-completion
```
