# fluxer-bin - Fluxer Desktop (https://fluxer.app), an Electron app.

# Upstream hosts versioned prebuilt binaries itself, so there is no
|
|
# build_artifact() here: on a new version only pkgver and the checksums
|
|
# are refreshed and the result is pushed to the AUR.
|
|
#
|
|
# Versions are date-based: 2026.920.41303 is the build published at
|
|
# 2026-09-20 04:13:03 UTC, the last field being the time of day without
|
|
# leading zeros. vercmp orders those correctly both within a day and across
|
|
# days, and every one of them outranks the 0.0.x versions this package
|
|
# carried until upstream changed schemes.
|
|
#
|
|
# The download API has one URL shape per channel, and this package follows
|
|
# "stable". Every build publishes a JSON manifest and a .sha256 next to its
|
|
# artifacts, so neither the version check nor the checksum refresh has to
|
|
# pull the ~130 MB tarballs to look at them.
|
|
#
|
|
# Upstream keeps only its last few builds per channel - everything under the
|
|
# old scheme is already gone, which is how a pinned 0.0.8 turned into a 404
|
|
# for anyone installing from the AUR. The version named here stays fetchable
|
|
# only while this repository keeps pace with the channel.

|
# build is a nightly, not what a package called fluxer-bin ships, so that
|
|
# is EX_TEMPFAIL rather than a version - see scripts/update-package.sh.

# a channel name in there would be one.
