2015-12-27splitfx: fixup frozen_string_literal for spawn
This only affected splitfx when it used the command option, and only when calling dtas-splitfx (not when playing splitfx files through the player).
2015-12-26remove vestigial mentions of opusenc
We removed support for opusenc back in May as it was not really suitable for audio production and a maintenance burden. ref: commit 7ca5d0bfc714c254c374af9cbc2e024a8b439725 ("splitfx: remove support for encoding opus")
2015-12-25enable "frozen_string_literal: true"
While we're in the area, make a wording change from "GPLv3 or later" to "GPL-3.0+", as the latter is favored by SPDX.org
2015-12-20mlib: fix update
We cannot use "dirname" in queries, oops :x
2015-12-16mlib: wire up search/find/stats to the UI
Not in any way a stable interface, yet, and still incomplete. This should emulate parts of the mpd protocol which should make it easier to debug and develop.
2015-12-15nodoc internal classes
DTAS does not expose any sort of public API for external users, so it will not be documented using RDoc. Currently all of our documentation is in plain-text or Markdown (only for manpages).
2015-12-14rg_state: fixup replaygain normalization
Oops, normalization is probably a forgotten feature...
2015-12-14player: implement software volume control
This is on a linear scale from 0.0 (mute) to 1.0 (no change) This is in the MPRIS spec and mpd as well (scaled to 0-100) This changes dtas-console key bindings (0/9) slightly to match mplayer more closely. ReplayGain preamp adjustment has moved from '0'/'9' to '7'/'8' keys. The 'm' key also toggles mute state (the pre-mute volume is stored in the dtas-console instance, not in dtas-player itself).
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.
2015-12-13unix_accepted: enable checking for readability after emit
Oops...
2015-12-13parse_time: enable frozen_string_literal
This is a new feature in Ruby 2.3 which can reduce allocations without adding ugly ".freeze" calls everywhere. This is a small enough file that we shouldn't have to worry about inadvertant breakage.
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.
2015-12-13player: reduce I/O priority of connected clients
Do not batch processing of requests or buffered output. We cannot have clients running "dtas-tl cat" or similar to dump a gigantic playlist cause us to have gaps in our playback. Since we implemented a tunable tracklist limit, we can also remove the hardcoded 100 element limit for buffered messages while we're at it; now the tracklist limit affects maximum memory use.
2015-12-13mlib: split out the output format from the library
The caller should dictate how the output format goes, not the library.
2015-12-13mlib: add find/search functionality based on mpd
This allows fast-ish tag searching, but the internal API is still subject to change to ease emulation of mpd.
2015-12-13mlib: no kwargs for 1.9.3 compatibility
We'll continue supporting Ruby 1.9.3 as long as Debian wheezy is supported.
2015-12-13mlib: add stats support
These are the same stats used by the mpd "stats" command.
2015-12-13mlib: remove non-existent entries
Files in a music library may be deleted or renamed, so our library should not persist old data. Unfortunately this double-stats all files, but using a hash for temporary storage could also bloat memory/disk usage and probably isn't worth it at the moment.
2015-12-13switch to exception-free non-blocking I/O
Ruby 2.3 will have `exception: false' support in socket-related classes. Additionally, 2.3 will implement the existing IO#*_nonblock methods more efficiently than before by avoiding the hash allocation necessary for keywords. For users on older Rubies, we'll continue supporting them with compatibility wrappers; even Ruby 1.9.3 users (for now).
2015-12-13tracklist: fixup idempotent "tl shuffle false"
Disabling shuffle should be idempotent.
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.
2015-12-06tracklist: avoid needlessly building a hash for track IDs
Building this hash is a linear operation anyways, so there's no point in doing it when Array#index can stop early if the track is found, to avoid unnecessary work.
2015-12-05tracklist: do not mutate @list when serializing
This happens when "dtas-ctl state dump" is invoked manually; causing "dtas-tl cat" to break afterwards. Fixes: commit 7b065706d37df9e54c8b3299ce696545c6159fa4 ("tracklist: use lower number unique track IDs")
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.
2015-11-28dtas-mlib: add dump support for debugging
Using an RFC-822-like format since YAML quoting rules aren't very human-friendly, and we already prevent newlines from entering our DB anyways.
2015-11-22introduce dtas-mlib for music library functions
Eventually this will support searching and be the basis of an mpd-compatible proxy in front of dtas-player
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.
2015-09-07player: add "queue cat" command
This will dump the contents of the current queue, including positional seeking information and commands. This is mainly intended for debugging and tools which rely on dtas internals.
2015-09-06use a common /dev/null
This allows us to avoid wasting time reopening the same device over and over again.
2015-07-18parse_freq: trivial new module for parsing frequencies
Seems a bit stupid, but oh well.
2015-07-18parse_time: pass through numeric types
This makes it easier to use in a user-friendly scripting interface we have coming up.
2015-06-16favor recv and recv_nonblock over recvmsg variants
We never use the full return value of the recvmsg* methods, so those allocations are wasted.
2015-06-15splitfx: set OUTFMT correctly for subenv if command is set
Oops!
2015-05-24splitfx: allow -p/--sox-pipe option
This allows splitfx YAML files to operate more seamlessly with external commands such as play(1) especially when combined with the -t/--trim option.
2015-05-21splitfx: simplify output display
No point in executing echo and wasting CPU cycles. We'll only waste cycles now during dry-runs
2015-05-20splitfx: documentation for subclasses
2015-05-20splitfx: drop unnecessary variable
We no longer use it since commit 7b47191aa4c88b3daa4c980013f0047cb7ae7f6d ("splitfx: avoid double-truncation with user command")
2015-05-19source/splitfx: allow watching extra external scripts
Since writing nested shell commands inside YAML is subject to all sorts of strange quoting rules, encourage users to rely on external scripts which the YAML file refers to instead. These scripts can be written in any reasonable scripting language capable of executing other commands. This allows transparently monitoring things such as `my-script.rb' in the below example when playing my-splitfx.yml via dtas-player: --------------------- my-splitfx.yml ----------------------- infile: input.flac command: $INDIR/my-script.rb "$INFILE" ... --------------------- my-script.rb -------------------------- #!/usr/bin/ruby require 'shellwords' infile = ARGV.shift ch = %W(sox #{infile} -p).concat((ENV['TRIMFX'] || '').shellsplit) fx = %W(highpass 25 gain 9) l = ch.dup.concat(%W(remix 1v1)).concat(fx).concat(%w(contrast 30)) r = ch.dup.concat(%W(remix 2v1)).concat(fx).concat(%w(contrast 0)) cmd = %W(sox -M |#{l.shelljoin} |#{r.shelljoin}) cmd.concat((ENV['SOXFMT'] || '-p').shellsplit) cmd.concat(%w(- stats)) warn cmd.inspect exec *cmd
2015-05-19splitfx: avoid double-truncation with user command
It's probably harmless as the sub (second) command is usually innocuous as fars a modifying dynamic range, but it makes the command-line output confusing.
2015-05-18splitfx: remove support for encoding opus
Lossy file encoding has too many tunable variables and it is not a good fit for an audio production tool such as dtas-splitfx. This was becoming a maintenance burden for me and is a sign of featuritis.
2015-05-18splitfx: show correct command for output
Oops...
2015-05-17process: implement array expansion to preserve spaces
This can make it easier to specify mcompand parameters in socks, as those require separate levels of parameter parsing and require quoting in shell.
2015-05-17dtas-splitfx: support --trim argument
It can often be useful to expose only part of a track for quick inspection. This lets us do that.
2015-05-17use monotonic clock on Ruby 2.1+
The monotonic clock is immune to stepping adjustments so it is more suitable for tracking elapsed time differences. Process.clock_gettime also generates less garbage on 64-bit systems due to the use of Flonum.
2015-05-10splitfx: fix non-generic, user-specified targets
Regression appeared in the previous commit, oops. commit ab63c7bb1b69423f8c39a60dd00230c560eecfc4 (splitfx: fix lossy output with player command is in use)
