=== What is hplaylist? === This is a utility for extracting the contents of an iTunes playlist and copying the associated files to an external MP3 player. I've tested this with a Sansa Clip running Rockbox, but any player that mounts like a USB disk and uses a similar directory structure should work. It assumes that playlists live in a folder called "Playlists" in the root player directory and music files live in a folder called "Music" in the root player directory. The Music folder can be (and is) organized according to artist and album. It should be easy to change the code to reflect a different directory structure. Patches to make this configurable rather than requiring source modifications would be welcome. The AppleScript contained in Applescript.hs does all the real work of dumping the contents of an iTunes playlist to a file. This code is adapter from Bery Rinaldo's "Export Playlist to M3U" script, found at: http://homepage.mac.com/beryrinaldo/AudioTron/Export_Playlist_to_M3U/ Due to the use of AppleScript, I expect that this application is Mac- only. But I would welcome patches to make it work on other platforms. === Installation === $ runhaskell Setup configure --configure-option=--music-player-root=/Volumes/SANSA\ CLIP \ --configure-option=--m4a-dir=/Users/tjc/converted $ runhaskell Setup build $ sudo runhaskell Setup install In place of "/Volumes/SANSA\ CLIP", substitute where your machine mounts your music player. In place of /Users/tjc/converted, substitute a cache directory containing .mp3 files. If you supply this config-time option and your playlist contains .m4a files, hplaylist will look in the cache directory for a corresponding .mp3 files instead of in wherever iTunes claims the file is. This is meant to support devices that can't play .m4a files. You can omit the --m4a-dir option, but you must supply the --music-player-root option. === Usage === $ hplaylist "gym February 2011" where the name in quotes is the name of an iTunes playlist. You can also do: $ hplaylist --dry-run "gym February 2011" and instead of copying files directly to your device, hplaylist will generate a shell script that, when executed, copies all the files in the "gym February 2011" playlist. For example, hplaylist might print out: To copy the files, execute the script /var/folders/Ig/Ig9WMUQwHsWDznqEdIsAfU+++TI/-Tmp-/hplaylist_copyit5084 and then you could read the file /var/folders/Ig/Ig9WMUQwHsWDznqEdIsAfU+++TI/-Tmp-/hplaylist_copyit5084 before you execute it, to make sure everything looks OK. === Gotchas === hplaylist will not delete any existing files on your player. It also won't clobber files with the same name that already exist. I usually just delete everything using the Finder, and run hplaylist to set things up afresh. === Github page === https://github.com/catamorphism/hplaylist === Known issues === Filenames containing special characters do not currently get escaped correctly. Such files get ignored. You'll have to rename your Moxy Früvoustracks or copy them by hand. === Further questions === Patches, bug reports: Tim Chevalier <chevalier@alum.wellesley.edu>
