m3uMaker 1.5 is finally available (see the project’s page for downloads and more information).
m3uMaker is a bash script that allows command line creation of m3u playlists for files within a certain folder. It is very flexible and can create playlists of files with any given set of terminations and immediately enqueue it (and play it, if you want) on any scriptable audio player.
An auxiliary configuration file for Konqueror is provided so playlists can be created/enqueued/played while browsing.
Until today, the only supported player was XMMS, but version 1.5 allows user specified enqueue/play commands to be used. Native support for Amarok has been added (’cause this is currently my player of choice).
Needless to say: m3uMaker is free… enjoy
[edit: a bug related to dereferencing symbolic links has been crushed, so the available version is 1.5.1]
