DESCRIPTION
I have combined my favourite features from dcd, cdcd, and mpg123 to
create Yet Another Front-End For Mpg123. (YAFEFM)
From dcd, I derived the ability to fork itself into the background.
From cdcd, I derived its intuitive interface.
With mpg123, I do the CPU-intensive work of actually playing the mp3s.
The end result is an MP3 player that is compliant with the
UNIX::Philosophy. Note that mp3 does not have a Captive User Interface.
Requests are made by mp3 to an MP3::Daemon::Simple and mp3 returns
immediately after getting a reply. The commands that generate output do
so on STDOUT. This makes mp3 easy to combine with other Unix utilities
via pipes and filters.
COMMANDS
Most of these commands are self-explanatory. One thing that may confuse
some people is that the playlist has a zero-based index. Otherwise, if
you're familiar with the cdcd interface, this should feel vaguely
familiar.
add This adds mp3s to the playlist. Multiple files may be specified.
del This deletes items from the playlist by index. More than one
index may be specified. If no index is specified, the last mp3
in the playlist is removed. Indices may also be negative in
which case they count from the end of the playlist.
play This plays the current mp3 if no other parameters are given.
This command also takes an optional parameter where the index of
an mp3 in the playlist may be given.
next This loads the next mp3 in the playlist.
prev This loads the previous mp3 in the playlist.
pause This pauses the currently playing mp3. If the mp3 was already
paused, this will unpause it. Note that using the play command
on a paused mp3 makes it start over from the beginning.
rw This rewinds an mp3 by the specified amount of seconds.
ff This fastforwards an mp3 by the specified amount of seconds.
jump This will go directly to a part of an mp3 specified by seconds
from the beginning of the track. If the number of seconds is
prefixed with either a "-" or a "+", a relative jump will be
made. This is another way to rewind or fastforward.
stop This stops the player.
time This sends back the index of the current track, the amount of
time that has elapsed, the amount of time that is left, and the
total amount of time. All times are reported in seconds.
info This sends back information about the current track.
ls This sends back a list of all mp3s currently in the playlist.
The current track is denoted by a line matching the regexp /^>/.
quit This unloads the MP3::Daemon::Simple that was automagically
spawned when you first invoked mp3.
FILES
$HOME/.mp3/mp3_socket
This is the socket used to communicate with the daemon. In the event
that the daemon is not cleanly shut down, this file may need to be
deleted before another MP3::Daemon::Simple can be started up.

The UNIX Philosophy
If you want to know what UNIX is all about, check this book out.
It's only 151 pages, and it's really easy and fun to read. Some
parts are a little biased and/or dated, but there is still a lot of
wisdom in it. I highly recommend it.
