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.

# concat-bin - Concat (https://github.com/jub0t/Concat), a free and
|
|
# open-source CapCut replacement: a Tauri 2 shell around a Rust video engine.
|
|
#
|
|
# Upstream publishes a Linux .deb per release, so there is no build step
|
|
# here: on a new version only pkgver, the asset name and the checksums are
|
|
# refreshed and the PKGBUILD repackages the .deb.
|
|
#
|
|
# The project has no stable release yet. Its build workflow publishes a
|
|
# "v<version>-alpha.<n>" prerelease for every green push to main, so /latest
|
|
# is empty and every tag is a prerelease - the alphas are what there is to
|
|
# package. They arrive several times a day, which is also how often this
|
|
# package can move.
|
|
#
|
|
# The release list is not ordered by version: GitHub sorts it by creation
|
|
# time, and upstream's alpha numbering has already run out of step with it
|
|
# (v0.2.0-alpha.10 sits between alpha.2 and alpha.1). The newest release is
|
|
# therefore picked by publication date rather than by list position.
|
|
#
|
|
# The asset name carries tauri.conf.json's version, not the tag - every alpha
|
|
# of 0.2.0 ships WolfCut_0.2.0_amd64.deb - so it cannot be derived from
|
|
# pkgver and is resolved through the API into the _asset variable.
|
|
#
|
|
# pkgver drops the hyphens from the tag (v0.2.0-alpha.15 -> 0.2.0alpha.15).
|
|
# pacman sorts that older than a later plain 0.2.0 (`vercmp 0.2.0alpha.15
|
|
# 0.2.0` is -1), so the prereleases upgrade to the eventual stable release on
|
|
# their own and no epoch is needed.
|
|
|
|
# Not on the AUR yet. concat-git goes up first; these two follow once the
|
|
# alpha-per-push release cadence has been lived with for a while - upstream
|
|
# publishes several a day, and each one is an AUR push (and, for concat, a
|
|
# full Rust build in CI). Flip this to true to publish; until then the
|
|
# PKGBUILD is still kept current and test-built here.
