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, Perl5, and some embedded shell, but may use other languages in
the future.
Changes:
dtas 0.20.0 - ruby 3.1+ compatibility, splitfx improvements
This release catches up with Psych (YAML) changes in Ruby 3.1+
Ruby 2.3+ is now the minimum version, though keep in mind the
ruby-core team already dropped support for it long ago.
Most of the features are focused on audio engineering
capabilities of dtas-splitfx. dtas-splitfx gains the --filter
switch, along with per-track environment variables and comments.
These new features have made my workflow significantly better.
dtas-archive supports explicit comments, and omits the default
SoX comment. To better cope with temporary and modified files
during editing, dtas-player metadata now checks ctime before
reusing the cache, handy for frequently-modified files.
"dtas-tl prune" is now supported to cull temporary files from
the player tracklist.
There's a few dtas-console improvements, too.
28 changes since v0.19.0 (2021-09-05):
archive: support comments, default to none
splitfx: use Etc.nprocessors for jobs if unspecified
dtas-console: set X11 terminal title iff DISPLAY is set
dtas-console: add 'i' toggle to show comments (metadata)
splitfx: fix track_zpad with integer arg
doc: drop ordered map from examples
player: reduce syscalls when splicing to single target
dtas-console: support Wayland terminal titles, too
console: workaround safe warnings in outdated `curses' gem
require Ruby 2.3+
get rid of DTAS.dedupe_str wrapper
move dtas-graph into script/, support Perl for dtas.sh
use YAML.unsafe_load in Psych 4.x (Ruby 3.1+)
deduplicate and freeze pathnames + metadata
player: remove omap conversion
dtas: drop unnecessary "require 'yaml'" statements
dtas-tl prune: cull missing files from tracklist
dtas-tl: drop encoding hacks, use binary stdout+stderr
use IO#wait_readable consistently
get rid of DTAS::Nonblock wrapper for Ruby <= 2.0
unix_accepted: drop Ruby < 2.3 support code
do not check IO#closed? before calling IO#close
splitfx: support per-track environment variables
splitfx: add --filter option to limit match to comments
player: expire sox metadata cache on file st_ctime changes
readahead: do not call -@ on non-String
splitfx: disallow combining --trim and --filter
splitfx: document changes ahead of 0.20.0 release

* [PATCH 3/3] player: expire sox metadata cache on file st_ctime changes

We still need the TTL to deal with fuse.sshfs and maybe other weird
FSes which don't return the st_ctime properly.
