# Runtime: Python 3 + SDL2 + a per-user pyxel install (created on first launch

%description
A graphical analog-stick calibration tool for SM8550-class Linux handhelds
(originally written by Cyril Deletre for the Retroid Pocket 5 / Mini, used by
ROCKNIX on the AYANEO Pocket DS via the rsinput driver).

The package installs the GPcal source under %{_datadir}/gpcal/ and a
/usr/bin/GPcal launcher that creates a per-user Python venv with pyxel on
first invocation, then runs main.py from that venv.

%prep
%setup -q -n GPcal-%{pkg_commit}

# Extract the pre-bundled application source tarball that the upstream uses
# for ROCKNIX. We then layer our launcher on top.
tar -xzf rocknix/gpcal.tgz

# Strip the pre-built Python venv that the upstream tarball ships under
# gpcal/pyxel/. It contains:
#   * x86_64-built native shared objects (would be Arch dependent in noarch)
#   * absolute symlinks /usr/share/gpcal/pyxel/bin/python3 -> /usr/bin/python3
# Both are RPM-build-blocking. Our launcher (/usr/bin/GPcal) creates a
# per-user pyxel venv on first invocation, so the embedded one is dead weight.
rm -rf gpcal/pyxel

# ROCKNIX's pre-build sed: the pocket-DS / pocket-EVO kernel exposes the
# joystick-tuning sysfs under /sys/module/rsinput/parameters, not the upstream
# /sys/module/retroid/parameters from the Retroid Pocket fork.
