Free Software command-line tools for audio playback, mastering, and
whatever else related to audio. dtas follows the worse-is-better
philosophy and acts as duct tape to combine existing command-line tools
for flexibility and ease-of-development. dtas is currently implemented
in Ruby (and some embedded shell), but may use other languages in the
future.
Changes: dtas 0.12.0 - many player updates
Notable additions for dtas-player music listeners.
dtas-ctl queue cat - display the internal queue
dtas-tl shuffle [true|false] - toggle tracklist shuffle
dtas-tl edit - open tracklist in an editor
see dtas-tl(1) manpage for more details on this:
http://dtas.80x24.org/dtas-tl.txt
The player tracklist now uses sequential track IDs instead of Ruby
object IDs, so it should be easier to use existing commands such as
"dtas-tl goto" and "dtas-tl remove"
For people using dtas-player for applying real-time effects to
splitfx YAML files, dtas-player can now watch for changes in scripts
specified in the "command" field of the splitfx YAML file.
Previously, dtas-player could only read the splitfx YAML file
itself. This requires GNU/Linux and the sleepy_penguin RubyGem
installed.
dtas-splitfx also learned some switches to allow easier
interoperability with other processing tools:
-p/--sox-pipe - identical to the sox(1) option
-t/--trim - only expose part of the track, useful when
combined with the above -p switch
See http://dtas.80x24.org/dtas-splitfx.txt for more details.
There's also some work-in-progress stuff that's not well documented
at the moment. As with anything pre-1.0, expect the possibility
of incompatible changes.
Since I'm not good at designing protocols, I've also started working
on mpd compatibility layer to allow using the normal music playback
stuff with more clients (some of the clients I actually like, unlike
the seemingly GUI-only landscape of MPRIS :P).
Of course, dtas-player itself has most the capabilities of a
Unix shell; and those capabilities will certainly not be available
to mpd or MPRIS clients.

Will probably release the current tree in a day or two with a few minor
tweaks, and have the mpd emulation proxy as a separate release in a few
more weeks.
The work-in-progress "mpd" branch is also pushed and
will be frequently rebased against master.
There's actually a lot of documentation stuff I'll need to catch
up on for the release. I tend to be better at writing commit messages
:x
And so, commit messages available below:
commit 1a63ca046d42dc9d35fe656c034e0c791834ae67
Author: Eric Wong <e@80x24.org>
Date: Mon Dec 7 11:04:32 2015 +0000
player: tl (repeat|shuffle|max) and trim swap values
It makes more sense to return the previous value
rather than the newly-set one, since the user presumably
knows what they're setting and might care about the
previous value.
commit ebf129cb0e067c204343bfdd3c73c38abae7f335
Author: Eric Wong <e@80x24.org>
Date: Mon Dec 7 10:43:07 2015 +0000
player: refactor and document tracklist interface
The dpc_tl method was becoming too large, split it up into
sub-methods for easier readability. While we're at it,
at least make "tl repeat" consistent with "tl shuffle"
when setting new values.
commit b08fe09e296524daf4de7ed16e0bed224f5008a2
Author: Eric Wong <e@80x24.org>
Date: Mon Dec 7 09:50:26 2015 +0000
tracklist: support limiting maximum tracklist size
This defaults to 16384? This is what mpd uses by default as well.
Of course folks interacting with dtas-player directly can override
this:
dtas-tl max INTEGER
dtas-tl max
This is NOT meant to be a hard security measure for local users
talking to dtas-player directly. It is only to prevent
accidentally stupid things like flooding the playlist with
a broken script and to prevent remote users from DoS-ing
us via the to-be-written mpd proxy/emulation layer.
Remember: dtas-player itself will ALWAYS remain capable of
executing arbitrary code :)
commit 3e013d3f24f0f935dce985d4c6bd155889e05dbb
Author: Eric Wong <e@80x24.org>
Date: Mon Dec 7 03:51:33 2015 +0000
tracklist: shuffle support
This is in the MPRIS 2.0 TrackList spec and also in mpd (as "repeat"
mode), so we can probably support it directly in player to ease
implementations of future wrappers.
