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console: workaround safe warnings in outdated `curses' gem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

This helps for folks creating and replacing many throwaway files
while editing with dtas-splitfx, or compulsive renamers.

"dtas-tl prune" can simplify life a bit for users who frequently
replace/rename tracks on their FS (I do it while editing audio
with dtas-splitfx).
Moving to Ruby 2.3 lets us depend on a bunch of newer APIs and
compatibility code can be dropped, since YARV instructions for
old versions still remain. The overall difference isn't very
noticeable, but the diffstat showing deleted lines is nice.
Eric Wong (9):
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
