class RemiAudio::Xspf::Playlist
- RemiAudio::Xspf::Playlist
- Reference
- Object
Overview
The Playlist
class contains general information about the playlist, as
well as a list of tracks. This also acts as the toplevel class for
XSPF/JSPF data, allowing you to read and write XSPF and JSPF files.
Reading an XSPF file:
playlist = File.open("/path/to/file.xspf", "r") do |file|
RemiAudio::Xspf::Playlist.read(file)
end
# Print the locations for every track
playlist.each do |trk|
puts trk.locations
end
Writing an XSPF file:
playlist = RemiAudio::Xspf::Playlist.new
playlist.title = "A Neat Playlist"
playlist.add(title: "Rabio", creator: "Partition 36", "/path/to/file/03 - Rabio.mp3")
playlist.add(title: "Searching for My Identity", creator: "Partition 36",
"/path/to/file/06 - Searching for My Identity.mp3")
puts playlist.write # Write XML to a String
playlist.write("/path/to/dest.xspf") # Write XSPF to a file
# Write JSPF to a file.
playlist.write("/path/to/dest.xspf", RemiAudio::Xspf::Playlist::Format::Json)
