# bottles-bin - prebuilt package of https://github.com/bottlesdevs/Bottles
# (GTK4 + LibAdwaita wine/proton prefix manager written in Python).
#
# Upstream only supports Flatpak officially and publishes no usable binary
# assets, so build_artifact() builds from the release tarball, carrying the
# same de-flatpak patch the AUR source package uses (upstream's meson refuses
# to configure outside a Flatpak sandbox and the code hard-requires the
# portal).

UPSTREAM_REPO="bottlesdevs/Bottles"

# fvs-lab/fvs2 (+ its core library) is AUR-only, so the binary is built here
# and bundled under /usr/lib/bottles. Versions pinned to the combination the
# AUR fvs2 package ships; bump on new fvs2 releases.
FVS2_VERSION=0.8.1
FVS2_CORE_VERSION=0.1.1

# Installed in CI (pacman) before build_artifact runs. blueprint-compiler
# resolves Gtk/Adw/GtkSource imports via their typelibs, hence the GUI libs.
