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.
Some playlist files can be really big. I plan on adding support for incremental parsing and generating via io-streams  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
