2015-12-14player: show "tracklist" hash with summary info with "current"
This allows clients to quickly query tracklist size/position/shuffle/random info.
2015-12-14tracklist: swap functionality
This (from the point of the client) will atomically swap two tracks. This should allow easily implementing of a tracklist editor.
2015-12-13player: dump state file asynchronously when requested
This avoids stalling when we have a gigantic tracklist.
2015-12-13player: support "tl clear" internally
It is orders of magnitude more efficient to implement this in the player and very noticeable when using large playlists.
2015-12-07player: 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.
2015-12-07player: 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.
2015-12-07tracklist: 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 :)
2015-12-07tracklist: 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.
2015-12-05tracklist: use lower number unique track IDs
This is easier for users to read and type; and _might_ help with race conditions due to fast object recycling from GC. We'll also be implementing playist versioning on top of this in the next commits for MPD protocol compatibility. Unfortunately this adds an additional 40 bytes of per-track overhead (on 64-bit systems, its only 20 bytes on 32-bit). However, we may be able to save memory in the future by supporting dtas-mlib node IDs if we integrate dtas-player with DTAS::Mlib. While we're at it, include a minor speedup for DTAS::Tracklist#remove_track by using Array#delete_at instead of relying on Array#compact! after assignment This should improve "dtas-tl cat" output readability dramatically. The state file (~/.dtas/player_state.yml) remains compatible between dtas-player before and after this change.
2015-10-04player: cleanup command dispatch
We can generate many command calls easily and dynamically, so avoid the code and cognitive overhead for the majority of commands.
2015-04-13cleanup: avoid redundant Array conversion for escapes
We already convert xs arg to be an Array, so avoid bloating our code with redundancy.
2015-01-28player: support the "trim" parameter
This feature is intended to allow users to "zoom-in" on a particular portion of a track to tweak parameters (either with dtas-sourceedit(1) or via playback of splitfx YAML files). This may be combined with looping the tracklist (via "tl repeat").
2015-01-20doc: describe most classes a bit
Hopefully this makes the code less daunting to newcomers
2015-01-19update copyright years and links to mailing list archives
The documentation part is managed by the new Documentation/update-copyright script. For the future, the rest may be managed by the update-copyright tool in gnulib
2015-01-19avoid aliasing global "spawn" method
This makes debugging, grepping, and following code confusing at times and also unexpected breaks usage of the global "spawn" method.
2015-01-19sinkedit: flesh out all parameters
dtas-sinkedit now shows default parameters in addition to user-changed parameters, allowing easier editing. Also, we need to be able to revert back to using the default pipe_size on Linux by setting pipe_size to nil (as an empty field in YAML).
2014-12-27player: support "source restart" command
This becomes useful for systems without inotify when we're editing YAML (or whatever) files frequently and want changes to be reflected right away during playback. This is a weaker version of the plain "restart" command, which restarts the entire playback chain.
2014-12-24restart "source ed" after env changes
Merely converting the `before' source information to a hash is not enough, as the `env' sub-hash is mosified in-place and shared with the `after' hash. So use `inspect' to serialize and snapshot the env and rely on a string comparison.
2014-10-21favor &:proc form instead of blocks in more places
This generates smaller bytecode and avoids unnecessary captures. Perhaps the Ruby optimizer can be taught to handle this automatically.
2014-08-26client_handler: minor cleanup (favor &:proc)
This reduces captures and is more consistent with our other code.
2014-06-06update copyrights and email address for 2014
I'm still normal, and still trolling, but 80x24.org will be epic :)
2013-12-06client_handler: style: prefer terser &:method form
We are Ruby 1.9+ only, so shorten our code just a little and hopefully make things easier-to-read.
2013-10-10player: "tl remove" properly stops current track
This simplifies the check for the current track and won't attempt to compare track IDs not on the tracklist.
2013-10-09player: "tl remove" drops the track from the queue
A paused/seeked track in the tracklist may end up in the queue.
2013-10-08player: "tl add" may trigger player start
The player should start playing the new track if the current tracklist is exhausted and not paused.
2013-10-06player: delay tracklist reset until asked to play
This prevents us from resetting the tracklist when we add new tracks and want to restart playback.
2013-10-05player: add factor out redundant condition check
The addition of a "need_to_queue" method should reduce the amount of cognitive overhead required to parse these conditions
2013-09-30player/client_handler: remove unused variables
Oops.
2013-09-30player (protocol): rename "tl previous" to "tl prev"
This gives us consistency with the "cue prev" command, is easier-to-type, and is consistent in length with "tl next". We'll just map "previous" -> "tl prev" when we implement the MPRIS bridge.
2013-09-30player: support seeking based on embedded cuesheet (FLAC)
This adds the ability to seek internally within FLAC file based on the internal CUE sheet. Other formats may be supported in the future, but FLAC is the only one I know of which supports embedded cue sheets. Note: flac 1.3.0 is recommended for users of non-CDDA-compatible formats. See updates to dtas-player_protocol(7) for details.
2013-09-30player: "tl goto" starts playback if idle (and not paused)
Using "tl goto" implies we start playback of the player is idle.
2013-09-28player: support bypass for rate, bits, channel
This may be used to avoid automatic: * resampling (rate) * down/upmixing (channel) * dither/truncation (bits) Using any bypass mode means we can no longer guarantee gapless playback for audio collections where rate, channel, or bits vary. This can however be useful when CPU usage is too high. This may also be useful in audio engineering situations.
2013-09-11player (tl add): do not repeat first track when idle
When a player is idle and a track is added to an empty tracklist, we should not repeat the first track added to the tracklist. Avoid that by advancing the tracklist to the current track.
2013-09-09player/client_handler: return count for list-style responses
This is necessary to handle the case where the tracklist is empty, clients get confused and timeout the response if we attempt to emit an empty string.
2013-09-09player: s/echo/wall/ for broadcasting to all watchers
"wall" is analogous to the wall(1) command, so we shall use that instead of echo.
2013-09-09tracklist: implement single-track repeat
Because sometimes a song is just stuck in our head. Or MPRIS 2.0 wants us to implement it this way...
2013-09-09player: "tl goto" takes optional offset arg in HHMMSS.SUBSEC
This should make implementing SetPosition in the MPRIS 2.0 spec possible.
2013-09-09player: implement previous/next commands
This means we can go back and forth in the tracklist like a normal music player. This will allow an easier MPRIS 2.0 implementation.
2013-09-09player/client_handler: prevent seek from excessive requeue
Otherwise we end up constantly pushing tracks to the top of the queue and getting surprising behavior if seek is called repeatedly.
2013-09-09player/client_handler: "tl add" returns track_id of added track
This allows easier scripting if we want to add a bunch of tracks
2013-09-09player: implement basic tracklist functionality
This should allow us to repeat through a list of tracks with relative ease. There is a rudimentary dtas-tl client implemented. This may be removed in the future.
2013-09-01player/client_handler: support for dumping individual env
This allows users to display the current env value for introspection
2013-09-01player/client_handler: cleanup to avoid redundant code
stop_sinks is already defined, so avoid repeating this loop
2013-09-01player: add "state dump" command to serialize state
This helps in case dtas-player is hit with SIGKILL or the system crashes. This does not fsync(2) as that could introduce delays on slow filesystems. Users should open the file manually and fsync themselves if they need to.
2013-08-29remove "encoding: binary" header use
We don't need it since IO#read(bytes, buf) will convert to ASCII-8BIT anyways. Everywhere else, we ensure path names are already binary. We do this mainly at the client layer before using Shellwords to escape the paths. We also must be careful about parsing output from soxi/avprobe which can show us metadata in whatever encoding is in the file. We must still handle data from parsing command output as binary, as the encoding of file metadata tends to vary. This also should buy us Syck compatibility for Ruby 1.9.3 users on Debian systems where Ruby 1.9.3 still uses Syck.
2013-08-28add license/copyright headers/footers to all files
All files we distribute in the tarball need to have a copyright/license specified for Savannah. We don't need the example state file anymore.
2013-08-27player: fix sink auto-restart on "sink ed" changes
I should really write a test case for this, maybe later.
2013-08-26client_handler: remove redundant checks for @current.pid
@current is only set if is active with a pid, now, so all of our checks for @current.pid are redundant and confusing.
2013-08-26player: restart sinks on "sink ed" modification
This is for consistency with source handlers.
2013-08-26player: sink ed pipe_size= disallows nils
While we're at it, add a test for this functionality, too.
