Simple lyrics plugin for the DeaDBeef Infobar plugin. All it does, however, is accept the artist and title of a song and print the lyrics to stdout, so it may be useful beyond this. It uses the Python package LyricsGenius by John Miller.
The dependencies are Python 3 and the lyricsgenius package. Unless you have a better way, install lyricsgenius like this:
sudo pip3 install lyricsgenius
Clone the git repository to wherever you want and cd into the new directory:
git clone https://github.com/MageJohn/genius-lyric-finder.git
cd genius-lyric-finder
You will also need an access token for the Genius API, for which you need a Genius account. Go to the Genius API Client management page, login, give an arbitrary name and a website (a link here will do), and click Save. Now get the Client Access Token and paste it into a file named access_token.txt next to the script.
To use the plugin from the Infobar plugin mark the script as executable:
chmod +x genius-lyric-finder.py
Then go into the Infobar preferences and set the "Lyric script path" option to point to genius-lyric-finder.py. You may want to disable the other lyric sources to make sure the script is used.
Using the script without the Infobar plugin is perfectly possible, though there's no command line interface to speak of. Just pass the name of the artist and the name of the song to the script. Extra arguments are ignored.
./genius-lyric-finder.py "Jethro Tull" "Broadsword"
The Infobar plugin encodes spaces with underscores, and so the script will replace underscores with spaces again; existing spaces are ignored.
