Concat (https://github.com/jub0t/Concat) is a Tauri 2 shell around a Rust
video engine, sold as a CapCut replacement. The project is mid-rename: the
binary, the desktop entry, the icons and the .deb asset all still say
WolfCut, so the packages install upstream's paths unchanged and add a
/usr/bin/concat symlink.
Upstream stages a static ffmpeg/ffprobe pair (180 MB) and whisper-cli
inside its bundle so the app runs on a machine with nothing installed.
Both lookups fall back to PATH, so concat-bin drops those two directories
and the source packages set WOLFCUT_SYSTEM_TOOLS=1 - the switch upstream
put in build.rs for exactly this case - leaving ffmpeg and whisper-cpp to
Arch. That is 17 MB installed instead of 225 MB.
!lto is not optional: makepkg's lto puts -flto=auto into CFLAGS, and ring
compiles hand-written assembly through cc, which then comes out as bitcode
and links to nothing.
sherpa-onnx-sys ships no C++ build; its build script downloads a prebuilt
static-lib archive. concat lists that archive as a checksummed source and
points the build script at it, with the version read out of upstream's
Cargo.lock by pkg.sh. concat-git cannot pin it - the version moves with
main - so there the build script fetches it.
Every upstream release is a v<version>-alpha.<n> prerelease published on a
push to main, several a day, and the release list is ordered by creation
rather than by version, so the newest is picked by publication date.
Only concat-git is published for now; concat and concat-bin are held back
with AUR_PUBLISH=false until that cadence has been lived with.
