# concat-bin - Concat (https://github.com/jub0t/Concat), a free and
|
|
# open-source CapCut replacement.
|
|
#
|
|
# Upstream builds the Linux release itself, so there is no build step here:
|
|
# on a new version the tag, the asset version and the checksums are refreshed
|
|
# and the PKGBUILD repackages upstream's .deb.
|
|
#
|
|
# 0.2.3 replaced the self-contained tarball this package used to take with a
|
|
# .deb, an .rpm and an AppImage, each for x86_64 and aarch64. Every release
|
|
# also carries a manifest.json listing each artifact with its sha256, so a
|
|
# new version costs two API calls and no download.
|
|
#
|
|
# The release list is not ordered by version: GitHub sorts it by creation
|
|
# time, and upstream's alpha numbering has run out of step with it before
|
|
# (v0.2.0-alpha.10 sat between alpha.2 and alpha.1). The newest release is
|
|
# therefore picked by publication date rather than by list position. Only
|
|
# tags that start with a version are considered, which is also what keeps the
|
|
# rolling "nightly" prerelease out.
|
|
#
|
|
# The asset name carries the workspace's version, not the tag - a prerelease
|
|
# of 0.2.4 ships Concat-0.2.4-linux-x86_64.deb whatever its tag says - so it
|
|
# cannot be derived from pkgver and is read from the manifest into _relver.
|
|
#
|
|
# pkgver drops the hyphens from the tag (v0.2.4-alpha.1 -> 0.2.4alpha.1).
|
|
# pacman sorts that older than a later plain 0.2.4 (`vercmp 0.2.4alpha.1
|
|
# 0.2.4` is -1), so prereleases upgrade to the eventual release on their own
|
|
# and no epoch is needed.
