Lyricer is an addon for waybar to display lyrics.

1. Read media using mpris

2. Fast and lightweight (<0.1% cpu usage, 1.9M after stripping)

3. Completely compatiable with waybar

Use cargo to build and install it.

cargo install lyricer

or

cargo build --release

Add following lines to your waybar configuration:

"modules-center": ["custom/lyrics"],
"custom/lyrics": {
    "format": "♪ {}",
    "interval": 1, 
    "exec": "/usr/bin/cat /tmp/lyrics", 
    "exec-if": "test -f /tmp/lyrics",
    "return-type": "json"
}

And don't forget to start lyricer in the background, preferrably with sway configutation.

Contrast to common implementation, lyricer will stay idle whenever it can. This means that the lyrics will not change untill they "suppose" to change according to the lrc file. Thus, when user manually change the audio, lyricer will not change untill the current lyrics line is finished.

Sometime the lyric will also lag regardless user interaction. The reason behind this is being investigated. PRs or helpful issues are welcome.

The following features are either planning or currently unable to archive:

1. Control media (pause, resume, next, previous) with buttons

2. Colorful output

3. More lyrics support (less error-prone)

4. Fix laggy performance

5. Manual selection of lyric file

Pull requests are welcome.
