Playlists is a library for working with media playlist files. The original motivation for the library was extracting URLs for streaming radio stations that use PLS and M3U playlist files.

The package also includes an executable that can dump the URLs from a playlist file and convert between playlist file formats.

• PLS
• M3U and M3U8

Some playlist files can be really big. I plan on adding support for incremental parsing and generating via pipes at some point in the future.

import qualified Data.ByteString as BS
import Text.Playlist

readPlaylist :: Format -> IO Playlist
readPlaylist fmt = do
  content <- BS.getContents
  case parsePlaylist fmt content of
    Left err -> fail $ "failed to parse playlist on stdin: " ++ err
    Right x  -> return x

$ playlist urls --format PLS < somefile.pls

$ playlist convert --from PLS --to M3U < somefile.pls
