# Lyrics
|
|
|
|
Lyrics adds a synchronized status-bar lyric display with album artwork, karaoke
|
|
highlighting, animated line changes, and configurable online or local sources.
|
|
|
|
## Plugin
|
|
|
|
| Field | Value |
|
|
| --- | --- |
|
|
| ID | `h465855hgg/lyrics` |
|
|
| Entries | Bar widget: `lyrics`; service: `service` |
|
|
|
|
## Requirements
|
|
|
|
Install `playerctl`, `python3`, `curl`, and `cp` on `PATH`. The active media
|
|
player must expose MPRIS metadata for automatic track and playback detection.
|
|
|
|
Noctalia installs the plugin files; it does not install system packages for you.
|
|
To check or install the runtime packages automatically, run:
|
|
|
|
```sh
|
|
sh scripts/setup-deps.sh --check
|
|
sh scripts/setup-deps.sh
|
|
```
|
|
|
|
Use `--yes` for unattended installs. The script supports `apt`, `dnf`,
|
|
`pacman`, `zypper`, `apk`, and `xbps-install`.
|
|
|
|
## Usage
|
|
|
|
Enable `h465855hgg/lyrics`, then add the `lyrics` bar widget in Noctalia's bar
|
|
settings. The background `service` detects the active MPRIS player, resolves
|
|
lyrics, downloads or caches album artwork, and publishes playback state to the
|
|
widget.
|
|
|
|
Left-click the widget to switch between lyrics and track information. Right-click
|
|
to pause or resume the active player. Paused content is dimmed and all lyric,
|
|
transition, and marquee animation stops until playback resumes.
|
|
|
|
When synchronized lyrics are unavailable, the widget displays
|
|
`track title + artist`. Long lines pause at each end while scrolling. Intro and
|
|
instrumental gaps can show a configurable cue such as `•••••`.

|
|
|
|
## IPC
|
|
|
|
External players can set `lyrics_source` to `external` and address the singleton
|
|
service with:
|
|
|
|
```sh
|
|
noctalia msg plugin h465855hgg/lyrics:service all <event> '<payload>'
|
|
```
|
|
|
|
Supported events:
|
|
|
|
- `push-lrc`: accepts synchronized or plain LRC text.
|
|
- `push-json`: accepts JSON with a `lines` timed array or a `lyrics` LRC string.
|
|
- `push-state`: also accepts `track`, `position`, `playing`, and `cover` fields.
|
|
- `clear`: clears the currently published lyrics.
|
|
|
|
Line timestamps and character timestamps are milliseconds. MPRIS track duration
|
|
and playback position are microseconds:
|
|
|
|
```json
|
|
{"lines":[{"time":1200,"duration":1800,"text":"Hello","chars":[1200,1500,1800,2100,2400]}]}
|
|
```
|
|
|
|
## Notes
|
|
|
|
Automatic mode requests LRCLIB first, then the public NetEase Music API. Custom
|
|
HTTP mode contacts only the configured endpoint. The plugin never reads browser
|
|
cookies or player credentials.
|
|
|
|
The service runs `playerctl` to read and control MPRIS playback, `python3` for the
|
|
LRCLIB helper and dynamic-lyric parser, `curl` for the public NetEase API, and
|
|
`cp` to preserve temporary local cover files. Query scratch files and downloaded
|
|
cover images are written inside the plugin runtime directory. Remote code is
|
|
never downloaded or executed.
