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 - Concat (https://github.com/jub0t/Concat), a free and open-source
|
|
# CapCut replacement: a Tauri 2 shell around a Rust video engine.
|
|
#
|
|
# Source package: the PKGBUILD builds the Tauri binary from the release
|
|
# tarball - the same executable upstream wraps into the .deb that concat-bin
|
|
# repackages. Upstream's flake.nix is the reference for what that needs, and
|
|
# this follows it: JS toolchain plus cargo, and WOLFCUT_SYSTEM_TOOLS=1 to opt
|
|
# out of staging a private ffmpeg/whisper-cli into the bundle, because Arch
|
|
# packages both and the app falls back to PATH.
|
|
#
|
|
# sherpa-onnx-sys, the text-to-speech backend, ships no C++ build: its build
|
|
# script downloads a prebuilt static-lib archive from the sherpa-onnx release
|
|
# page. The PKGBUILD lists that archive as a source and points the build
|
|
# script at it (SHERPA_ONNX_ARCHIVE_DIR), so the binary is checksummed by
|
|
# makepkg rather than fetched unverified mid-build. Its version has to follow
|
|
# upstream's Cargo.lock, so refresh_checksums() reads it from the tarball and
|
|
# syncs the _sherpa variable in the PKGBUILD.
|
|
#
|
|
# Release/version handling is identical to concat-bin: every upstream release
|
|
# is a "v<version>-alpha.<n>" prerelease published on a push to main, the
|
|
# release list is ordered by creation rather than by version (v0.2.0-alpha.10
|
|
# sits between alpha.2 and alpha.1), so the newest is picked by publication
|
|
# date, and pkgver drops the hyphens - see concat-bin/pkg.sh.
|
|
|
|
# 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.
