Spfy is a command-line tool for generating XSPF playlists from metadata stored in several popular audio formats and is developed entirely in Ruby. It takes one or more local directory paths as input, extracts metadata tags from any audio files that it encounters, and generates a valid XSPF playlist.
A working Ruby installation (version 1.9 or greater) is required for Spfy to work, but this is outside the scope of this guide. For more information refer to the official installation procedure.
TagLib is also required. Follow the steps below (taken from the taglib-ruby installation guide) to install the necessary files for your respective system type:
| System: | Command: |
|---|---|
| Debian/Ubuntu | sudo apt-get install libtag1-dev |
| Fedora/RHEL | sudo yum install taglib-devel |
| Brew | brew install taglib |
| MacPorts | sudo port install taglib |
With the prerequisites above taken care of Spfy can be installed with the following command:
$ gem install spfy
By default, Spfy will output a formatted XSPF playlist to the standard output stream that will include location, title, creator, album, and trackNum elements for each audio file where available.
The general syntax for Spfy is spfy [options] dir1 ... dirN, where dir1 ... dirN is one or more paths to directories containing audio files.
For example:
$ spfy ~/music
..will produce the following output (where ~/music contains one audio file with valid metadata):
<?xml version="1.0" encoding="UTF-8"?>
<playlist version="1" xmlns="http://xspf.org/ns/0/">
<trackList>
<track>
<location>file:///Users/spfy/music/03%20A%20Stitch%20In%20Time.mp3</location>
<title>A Stitch In Time</title>
<creator>The Smashing Pumpkins</creator>
<album>Teargarden by Kaleidyscope</album>
<trackNum>3</trackNum>
</track>
</trackList>
</playlist>Spfy supports multiple directory paths (e.g. spfy /dir1 /dir2) and traverses each directory recursively by default. Unsupported files and empty directories in a directory tree are silently ignored and will not impact Spfy's output.
Command-line arguments allow you to control which elements Spfy outputs:
-f, --no-location Suppress file location output
-t, --no-title Suppress track title in output
-a, --no-artist Suppress artist name in output
-l, --no-album Suppress album name in output
-n, --no-tracknum Suppress track number in output
