playlist

Parse playlist files

Install

In your mix.exs:

defp deps do
  [
    {:playlist, "~> 1.0.0"}
  ]
end

Then run mix deps.get.

Usage

This package can parse M3U and PLS files and exports two modules: Playlist.M3U and Playlist.PLS. Both of these export a parse/1 function, which takes a string representing a playlist file and returns a list of maps, each representing a track in the file.

Example

Let's assume we have a M3U file that looks like this:

#EXTM3U
#EXTINF:822,A - Track 1
~/Music/1.mp3
#EXTINF:272,B - Track 2
mp3/b/2.ogg
#EXTINF:381,C - Track 3
http://coolmusic.com/12345.m4a
#EXTINF:249,D - Track 4
ws://nice.com/54321.aac
#EXTINF:249,E - Track 5
wss://192.168.1.1/llllllll.mp3

We can parse it like this:

{:ok, file} = File.read("playlist.m3u")
{:ok, parsed} = Playlist.M3U.parse(file)

parsed will look like this:

[
  %{artist: "A ", file: "~/Music/1.mp3", length: "822", title: "Track 1"},
  %{artist: "B ", file: "mp3/b/2.ogg", length: "272", title: "Track 2"},
  %{artist: "C ", file: "http://coolmusic.com/12345.m4a", length: "381", title: "Track 3"},
  %{artist: "D ", file: "ws://nice.com/54321.aac", length: "249", title: "Track 4"},
  %{artist: "E ", file: "wss://192.168.1.1/llllllll.mp3", length: "249", title: "Track 5"}
]

Any error during the parsing will result in a {:error, reason} tuple.
